Introduction to ARCnet
22
======================
24
ARCnet is a network type which works in a way similar to popular Ethernet
25
networks but which is also different in some very important ways.
27
First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
28
(slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
29
there are others as well, but these are less common. The different hardware
30
types, as far as I'm aware, are not compatible and so you cannot wire a
31
100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
32
work with 100 Mbps cards, but I haven't been able to verify this myself,
33
since I only have the 2.5 Mbps variety. It is probably not going to saturate
34
your 100 Mbps card. Stop complaining. :)
36
You also cannot connect an ARCnet card to any kind of Ethernet card and
37
expect it to work.
39
There are two "types" of ARCnet - STAR topology and BUS topology. This
40
refers to how the cards are meant to be wired together. According to most
41
available documentation, you can only connect STAR cards to STAR cards and
42
BUS cards to BUS cards. That makes sense, right? Well, it's not quite
43
true; see below under "Cabling."
45
Once you get past these little stumbling blocks, ARCnet is actually quite a
46
well-designed standard. It uses something called "modified token passing"
47
which makes it completely incompatible with so-called "Token Ring" cards,
48
but which makes transfers much more reliable than Ethernet does. In fact,
49
ARCnet will guarantee that a packet arrives safely at the destination, and
50
even if it can't possibly be delivered properly (ie. because of a cable
51
break, or because the destination computer does not exist) it will at least
52
tell the sender about it.
54
Because of the carefully defined action of the "token", it will always make
55
a pass around the "ring" within a maximum length of time. This makes it
56
useful for realtime networks.
58
In addition, all known ARCnet cards have an (almost) identical programming
59
interface. This means that with one ARCnet driver you can support any
60
card, whereas with Ethernet each manufacturer uses what is sometimes a
61
completely different programming interface, leading to a lot of different,
62
sometimes very similar, Ethernet drivers. Of course, always using the same
63
programming interface also means that when high-performance hardware
64
facilities like PCI bus mastering DMA appear, it's hard to take advantage of
65
them. Let's not go into that.
67
One thing that makes ARCnet cards difficult to program for, however, is the
68
limit on their packet sizes; standard ARCnet can only send packets that are
69
up to 508 bytes in length. This is smaller than the Internet "bare minimum"
70
of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
71
level of encapsulation is defined by RFC1201, which I call "packet
72
splitting," that allows "virtual packets" to grow as large as 64K each,
73
although they are generally kept down to the Ethernet-style 1500 bytes.
75

76
advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

Cabling ARCnet Networks
83
=======================
85
This section was rewritten by
87
Vojtech Pavlik <[email protected]>
89
using information from several people, including:
91
- Avery Pennraun <[email protected]>
92
- Stephen A. Wood <[email protected]>
93
- John Paul Morrison <[email protected]>
94
- Joachim Koenig <[email protected]>
96
and Avery touched it up a bit, at Vojtech's request.
98
ARCnet (the classic 2.5 Mbps version) can be connected by two different
99
types of cabling: coax and twisted pair. The other ARCnet-type networks
100
(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
101
cabling (Type1, Fiber, C1, C4, C5).
103
For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
104
also work fine, because ARCnet is a very stable network. I personally use 75
105
Ohm TV antenna cable.
107
Cards for coax cabling are shipped in two different variants: for BUS and
108
STAR network topologies. They are mostly the same. The only difference
109
lies in the hybrid chip installed. BUS cards use high impedance output,
110
while STAR use low impedance. Low impedance card (STAR) is electrically
111
equal to a high impedance one with a terminator installed.
113
Usually, the ARCnet networks are built up from STAR cards and hubs. There
114
are two types of hubs - active and passive. Passive hubs are small boxes
115
with four BNC connectors containing four 47 Ohm resistors::
117
| | wires
118
R + junction
119
-R-+-R- R 47 Ohm resistors
120
R
121
|
123
The shielding is connected together. Active hubs are much more complicated;
124
they are powered and contain electronics to amplify the signal and send it
125
to other segments of the net. They usually have eight connectors. Active
126
hubs come in two variants - dumb and smart. The dumb variant just
127
amplifies, but the smart one decodes to digital and encodes back all packets
128
coming through. This is much better if you have several hubs in the net,
129
since many dumb active hubs may worsen the signal quality.
131
And now to the cabling. What you can connect together:
133
1. A card to a card. This is the simplest way of creating a 2-computer
134
network.
136
2. A card to a passive hub. Remember that all unused connectors on the hub
137
must be properly terminated with 93 Ohm (or something else if you don't
138
have the right ones) terminators.
140
(Avery's note: oops, I didn't know that. Mine (TV cable) works
141
anyway, though.)
143
3. A card to an active hub. Here is no need to terminate the unused
144
connectors except some kind of aesthetic feeling. But, there may not be
145
more than eleven active hubs between any two computers. That of course
146
doesn't limit the number of active hubs on the network.
148
4. An active hub to another.
150
5. An active hub to passive hub.
152
Remember that you cannot connect two passive hubs together. The power loss
153
implied by such a connection is too high for the net to operate reliably.
155
An example of a typical ARCnet network::
157
R S - STAR type card
158
S------H--------A-------S R - Terminator
159
| | H - Hub
160
| | A - Active hub
161
| S----H----S
162
S |
163
|
164
S
166
The BUS topology is very similar to the one used by Ethernet. The only
167
difference is in cable and terminators: they should be 93 Ohm. Ethernet
168
uses 50 Ohm impedance. You use T connectors to put the computers on a single
169
line of cable, the bus. You have to put terminators at both ends of the
170
cable. A typical BUS ARCnet network looks like::
172
RT----T------T------T------T------TR
173
B B B B B B
175
B - BUS type card
176
R - Terminator
177
T - T connector
179
But that is not all! The two types can be connected together. According to
180
the official documentation the only way of connecting them is using an active
181
hub::
183
A------T------T------TR
184
| B B B
185
S---H---S
186
|
187
S
189
The official docs also state that you can use STAR cards at the ends of
190
BUS network in place of a BUS card and a terminator::
192
S------T------T------S
193
B B
195
But, according to my own experiments, you can simply hang a BUS type card
196
anywhere in middle of a cable in a STAR topology network. And more - you
197
can use the bus card in place of any star card if you use a terminator. Then
198
you can build very complicated networks fulfilling all your needs! An
199
example::
201

A basically different cabling scheme is used with Twisted Pair cabling. Each
215
of the TP cards has two RJ (phone-cord style) connectors. The cards are
216
then daisy-chained together using a cable connecting every two neighboring
217
cards. The ends are terminated with RJ 93 Ohm terminators which plug into
218
the empty connectors of cards on the ends of the chain. An example::
220
___________ ___________
221
_R_|_ _|_|_ _|_R_
222
| | | | | |
223
|Card | |Card | |Card |
224
|_____| |_____| |_____|
227
There are also hubs for the TP topology. There is nothing difficult
228
involved in using them; you just connect a TP chain to a hub on any end or
229
even at both. This way you can create almost any network configuration.
230
The maximum of 11 hubs between any two computers on the net applies here as
231
well. An example::
233
RP-------P--------P--------H-----P------P-----PR
234
|
235
RP-----H--------P--------H-----P------PR
236
| |
237
PR PR
239
R - RJ Terminator
240
P - TP Card
241
H - TP Hub
243
Like any network, ARCnet has a limited cable length. These are the maximum
244
cable lengths between two active ends (an active end being an active hub or
245
a STAR card).
247
========== ======= ===========
248
RG-62 93 Ohm up to 650 m
249
RG-59/U 75 Ohm up to 457 m
250
RG-11/U 75 Ohm up to 533 m
251
IBM Type 1 150 Ohm up to 200 m
252
IBM Type 3 100 Ohm up to 100 m
253
========== ======= ===========
255
The maximum length of all cables connected to a passive hub is limited to 65
256
meters for RG-62 cabling; less for others. You can see that using passive
257
hubs in a large network is a bad idea. The maximum length of a single "BUS
258
Trunk" is about 300 meters for RG-62. The maximum distance between the two
259
most distant points of the net is limited to 3000 meters. The maximum length
260
of a TP cable between two cards/hubs is 650 meters.
263
Setting the Jumpers
264
===================
266
All ARCnet cards should have a total of four or five different settings:
268
- the I/O address: this is the "port" your ARCnet card is on. Probed
269
values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
270
your card has additional ones, which is possible, please tell me.) This
271
should not be the same as any other device on your system. According to
272
a doc I got from Novell, MS Windows prefers values of 0x300 or more,
273
eating net connections on my system (at least) otherwise. My guess is
274
this may be because, if your card is at 0x2E0, probing for a serial port
275
at 0x2E8 will reset the card and probably mess things up royally.
277
- Avery's favourite: 0x300.
279
- the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
280
on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
282
Make sure this is different from any other card on your system. Note
283
that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
284
"cat /proc/interrupts" for a somewhat complete list of which ones are in
285
use at any given time. Here is a list of common usages from Vojtech
286
Pavlik <[email protected]>:
288
("Not on bus" means there is no way for a card to generate this
289
interrupt)
291
====== =========================================================
292
IRQ 0 Timer 0 (Not on bus)
293
IRQ 1 Keyboard (Not on bus)
294
IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
295
IRQ 3 COM2
296
IRQ 4 COM1
297
IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
298
IRQ 6 Floppy disk controller
299
IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP)
300
IRQ 8 Realtime Clock Interrupt (Not on bus)
301
IRQ 9 FREE (VGA vertical sync interrupt if enabled)
302
IRQ 10 FREE
303
IRQ 11 FREE
304
IRQ 12 FREE
305
IRQ 13 Numeric Coprocessor (Not on bus)
306
IRQ 14 Fixed Disk Controller
307
IRQ 15 FREE (Fixed Disk Controller 2 if you have it)
308
====== =========================================================
311
.. note::
313
IRQ 9 is used on some video cards for the "vertical retrace"
314
interrupt. This interrupt would have been handy for things like
315
video games, as it occurs exactly once per screen refresh, but
316
unfortunately IBM cancelled this feature starting with the original
317
VGA and thus many VGA/SVGA cards do not support it. For this
318
reason, no modern software uses this interrupt and it can almost
319
always be safely disabled, if your video card supports it at all.
321
If your card for some reason CANNOT disable this IRQ (usually there
322
is a jumper), one solution would be to clip the printed circuit
323
contact on the board: it's the fourth contact from the left on the
324
back side. I take no responsibility if you try this.
326
- Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
328
- the memory address: Unlike most cards, ARCnets use "shared memory" for
329
copying buffers around. Make SURE it doesn't conflict with any other
330
used memory in your system!
332
::
334
A0000 - VGA graphics memory (ok if you don't have VGA)
335
B0000 - Monochrome text mode
336
C0000 \ One of these is your VGA BIOS - usually C0000.
337
E0000 /
338
F0000 - System BIOS
340
Anything less than 0xA0000 is, well, a BAD idea since it isn't above
341
640k.
343
- Avery's favourite: 0xD0000
345
- the station address: Every ARCnet card has its own "unique" network
346
address from 0 to 255. Unlike Ethernet, you can set this address
347
yourself with a jumper or switch (or on some cards, with special
348
software). Since it's only 8 bits, you can only have 254 ARCnet cards
349
on a network. DON'T use 0 or 255, since these are reserved (although
350
neat stuff will probably happen if you DO use them). By the way, if you
351
haven't already guessed, don't set this the same as any other ARCnet on
352
your network!
354
- Avery's favourite: 3 and 4. Not that it matters.
356
- There may be ETS1 and ETS2 settings. These may or may not make a
357
difference on your card (many manuals call them "reserved"), but are
358
used to change the delays used when powering up a computer on the
359
network. This is only necessary when wiring VERY long range ARCnet
360
networks, on the order of 4km or so; in any case, the only real
361
requirement here is that all cards on the network with ETS1 and ETS2
362
jumpers have them in the same position. Chris Hindy <[email protected]>
363
sent in a chart with actual values for this:

Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
375
network.
377
Also, on many cards (not mine, though) there are red and green LED's.

Even if your ARCnet model isn't listed, but has the same jumpers as another
408
model that is, please e-mail me to say so.

578
The PC130E is an enhanced version of the PC130 board, is equipped with a
579
standard BNC female connector for connection to RG-62/U coax cable.
580
Since this board is designed both for point-to-point connection in star
581
networks and for connection to bus networks, it is downwardly compatible
582
with all the other standard boards designed for coax networks (that is,
583
the PC120, PC110 and PC100 star topology boards and the PC220, PC210 and
584
PC200 bus topology boards).
586
The PC270E is an enhanced version of the PC260 board, is equipped with two
587
modular RJ11-type jacks for connection to twisted pair wiring.
588
It can be used in a star or a daisy-chained network.

637
Setting the Node ID
638
^^^^^^^^^^^^^^^^^^^
640
The eight switches in group S2 are used to set the node ID.
641
These switches work in a way similar to the PC100-series cards; see that
642
entry for more information.
645
Setting the I/O Base Address
646
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
648
The first three switches in switch group S1 are used to select one
649
of eight possible I/O Base addresses using the following table::
652
Switch | Hex I/O
653
1 2 3 | Address
654
-------|--------

665
Setting the Base Memory (RAM) buffer Address
666
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
668
The memory buffer requires 2K of a 16K block of RAM. The base of this
669
16K block can be located in any of eight positions.
670
Switches 4-6 of switch group S1 select the Base of the 16K block.
671
Within that 16K address space, the buffer may be assigned any one of four
672
positions, determined by the offset, switches 7 and 8 of group S1.

*) To enable the 8K Boot PROM install the jumper ROM.
720
The default is jumper ROM not installed.
723
Setting the Timeouts and Interrupt
724
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
726
The jumpers labeled EXT1 and EXT2 are used to determine the timeout
727
parameters. These two jumpers are normally left open.
729
To select a hardware interrupt level set one (only one!) of the jumpers
730
IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
733
Configuring the PC130E for Star or Bus Topology
734
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
736
The single jumper labeled STAR is used to configure the PC130E board for
737
star or bus topology.
738
When the jumper is installed, the board may be used in a star network, when
739
it is removed, the board can be used in a bus topology.
742
Diagnostic LEDs
743
^^^^^^^^^^^^^^^
745
Two diagnostic LEDs are visible on the rear bracket of the board.
746
The green LED monitors the network activity: the red one shows the
747
board activity::
749
Green | Status Red | Status
750
-------|------------------- ---------|-------------------
751
on | normal activity flash/on | data transfer
752
blink | reconfiguration off | no data transfer;
753
off | defective board or | incorrect memory or
754
| node ID is zero | I/O address
757
PC500/PC550 Longboard (16-bit cards)
758
------------------------------------
760
- from Juergen Seifert <[email protected]>
763
.. note::
765
There is another Version of the PC500 called Short Version, which
766
is different in hard- and software! The most important differences
767
are:
769
- The long board has no Shared memory.
770
- On the long board the selection of the interrupt is done by binary
771
coded switch, on the short board directly by jumper.
773
[Avery's note: pay special attention to that: the long board HAS NO SHARED
774
MEMORY. This means the current Linux-ARCnet driver can't use these cards.
775
I have obtained a PC500Longboard and will be doing some experiments on it in
776
the future, but don't hold your breath. Thanks again to Juergen Seifert for
777
his advice about this!]

845
Setting the Node ID
846
^^^^^^^^^^^^^^^^^^^
848
The eight switches in group SW3 are used to set the node ID. Each node
849
attached to the network must have an unique node ID which must be
850
different from 0.
851
Switch 1 serves as the least significant bit (LSB).
853
The node ID is the sum of the values of all switches set to "1"
854
These values are::
856
Switch | Value
857
-------|-------
858
1 | 1
859

Setting the I/O Base Address
887
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
889
The first six switches in switch group SW1 are used to select one
890
of 32 possible I/O Base addresses using the following table::
892
Switch | Hex I/O
893

Setting the Interrupt
930
^^^^^^^^^^^^^^^^^^^^^
932
Switches seven through ten of switch group SW1 are used to select the
933
interrupt level. The interrupt level is binary coded, so selections
934
from 0 to 15 would be possible, but only the following eight values will
935
be supported: 3, 4, 5, 7, 9, 10, 11, 12.

952
Setting the Timeouts
953
^^^^^^^^^^^^^^^^^^^^
955
The two jumpers JP2 (1-4) are used to determine the timeout parameters.
956
These two jumpers are normally left open.
957
Refer to the COM9026 Data Sheet for alternate configurations.
960
Configuring the PC500 for Star or Bus Topology
961
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
963
The single jumper labeled JP6 is used to configure the PC500 board for
964
star or bus topology.
965
When the jumper is installed, the board may be used in a star network, when
966
it is removed, the board can be used in a bus topology.
969
Diagnostic LEDs
970
^^^^^^^^^^^^^^^
972
Two diagnostic LEDs are visible on the rear bracket of the board.
973
The green LED monitors the network activity: the red one shows the
974
board activity::
976
Green | Status Red | Status
977
-------|------------------- ---------|-------------------
978
on | normal activity flash/on | data transfer
979
blink | reconfiguration off | no data transfer;

------------------
987
- from J.S. van Oosten <[email protected]>
989
Note: this data is gathered by experimenting and looking at info of other
990
cards. However, I'm sure I got 99% of the settings right.
992
The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
993
LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::

|||||||||||||||||||||
1014
The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
1015
labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
1016
IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
1018
S1 and S2 perform the same function as on the PC270, only their numbers
1019
are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
1021
I know it works when connected to a PC110 type ARCnet board.

LCS-8830(-T) (8 and 16-bit cards)
1030
---------------------------------
1032
- from Mathias Katzer <[email protected]>
1033
- Marek Michalkiewicz <[email protected]> says the
1034
LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
1035
only (the JP0 jumper is hardwired), and BNC only.
1037
This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
1038
nowhere else, not even on the few Xeroxed sheets from the manual).

PDI507 (8-bit card)
1149
--------------------
1151
- from Mark Rejhon <[email protected]> (slight modifications by Avery)
1152
- Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
1153
are mostly the same as this. PDI508Plus cards appear to be mainly
1154
software-configured.
1156
Jumpers:
1158
There is a jumper array at the bottom of the card, near the edge
1159
connector. This array is labelled J1. They control the IRQs and
1160
something else. Put only one jumper on the IRQ pins.
1162
ETS1, ETS2 are for timing on very long distance networks. See the
1163
more general information near the top of this file.
1165
There is a J2 jumper on two pins. A jumper should be put on them,
1166
since it was already there when I got the card. I don't know what
1167
this jumper is for though.
1169
There is a two-jumper array for J3. I don't know what it is for,
1170
but there were already two jumpers on it when I got the card. It's
1171
a six pin grid in a two-by-three fashion. The jumpers were
1172
configured as follows::
1174

- If using coax cable in a bus topology the J4 jumper must be removed;
1196
place it on one pin.
1198
- If using bus topology with twisted pair wiring move the J3
1199
jumpers so they connect the middle pin and the pins closest to the RJ11
1200
Connectors. Also the J4 jumper must be removed; place it on one pin of
1201
J4 jumper for storage.
1203
- If using star topology with twisted pair wiring move the J3
1204
jumpers so they connect the middle pin and the pins closest to the RJ11
1205
connectors.
1208
DIP Switches:
1210
The DIP switches accessible on the accessible end of the card while
1211
it is installed, is used to set the ARCnet address. There are 8
1212
switches. Use an address from 1 to 254
1214
========== =========================
1215
Switch No. ARCnet address
1216

11111110 1
1224
11111111 0 (Don't use this!)
1225
========== =========================
1227
There is another array of eight DIP switches at the top of the
1228
card. There are five labelled MS0-MS4 which seem to control the
1229
memory address, and another three labelled IO0-IO2 which seem to
1230
control the base I/O address of the card.
1232
This was difficult to test by trial and error, and the I/O addresses
1233
are in a weird order. This was tested by setting the DIP switches,
1234
rebooting the computer, and attempting to load ARCETHER at various
1235
addresses (mostly between 0x200 and 0x400). The address that caused
1236
the red transmit LED to blink, is the one that I thought works.
1238
Also, the address 0x3D0 seem to have a special meaning, since the
1239
ARCETHER packet driver loaded fine, but without the red LED
1240
blinking. I don't know what 0x3D0 is for though. I recommend using
1241
an address of 0x300 since Windows may not like addresses below
1242
0x300.
1244

1254
001 0x380
1255

1256
============= ===========
1258
The memory switches set a reserved address space of 0x1000 bytes
1259
(0x100 segment units, or 4k). For example if I set an address of
1260
0xD000, it will use up addresses 0xD000 to 0xD100.
1262
The memory switches were tested by booting using QEMM386 stealth,
1263
and using LOADHI to see what address automatically became excluded
1264
from the upper memory regions, and then attempting to load ARCETHER
1265
using these addresses.
1267
I recommend using an ARCnet memory address of 0xD000, and putting
1268
the EMS page frame at 0xC000 while using QEMM stealth mode. That
1269
way, you get contiguous high memory from 0xD100 almost all the way
1270
the end of the megabyte.
1272
Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
1273
on my card. It could be malfunctioning on my card. Experiment with
1274
it ON first, and if it doesn't work, set it to OFF. (It may be a
1275
modifier for the 0x200 bit?)

1374
Setting the Node ID
1375
^^^^^^^^^^^^^^^^^^^
1377
The eight switches in SW2 are used to set the node ID. Each node attached
1378
to the network must have an unique node ID which must be different from 0.
1379
Switch 1 (ID0) serves as the least significant bit (LSB).
1381
The node ID is the sum of the values of all switches set to "1"
1382
These values are:

Setting the I/O Base Address
1417
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1419
The last three switches in switch block SW1 are used to select one
1420
of eight possible I/O Base addresses using the following table::
1423
Switch | Hex I/O
1424
6 7 8 | Address
1425
------------|--------
1426
ON ON ON | 260
1427

1428
ON OFF ON | 2E0 (Manufacturer's default)
1429
OFF OFF ON | 2F0
1430
ON ON OFF | 300
1431
OFF ON OFF | 350
1432
ON OFF OFF | 380
1433
OFF OFF OFF | 3E0
1436
Setting the Base Memory (RAM) buffer Address
1437
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1439
The memory buffer (RAM) requires 2K. The base of this buffer can be
1440
located in any of eight positions. The address of the Boot Prom is
1441
memory base + 8K or memory base + 0x2000.
1442
Switches 1-5 of switch block SW1 select the Memory Base address.
1444

1455
ON ON ON OFF OFF | DC000 | DE000
1456
ON ON OFF OFF OFF | E0000 | E2000
1458
*) To enable the Boot ROM install the jumper JP1
1460
.. note::
1462
Since the switches 1 and 2 are always set to ON it may be possible
1463
that they can be used to add an offset of 2K, 4K or 6K to the base
1464
address, but this feature is not documented in the manual and I
1465
haven't tested it yet.
1468
Setting the Interrupt Line
1469
^^^^^^^^^^^^^^^^^^^^^^^^^^
1471
To select a hardware interrupt level install one (only one!) of the jumpers
1472
JP2, JP3, JP4, JP5, JP6. JP2 is the default::
1474
Jumper | IRQ

Setting the Internal Terminator on CN120AB/TP/SBT
1484
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1486
The jumper JP12 is used to enable the internal terminator::

1585
Setting the Node ID
1586
^^^^^^^^^^^^^^^^^^^
1588
The eight switches in SW2 are used to set the node ID. Each node attached
1589
to the network must have an unique node ID which must be different from 0.
1590
Switch 1 (ID0) serves as the least significant bit (LSB).
1592
The node ID is the sum of the values of all switches set to "1"
1593
These values are::
1595
Switch | Label | Value
1596
-------|-------|-------
1597
1 | ID0 | 1
1598
2 | ID1 | 2
1599
3 | ID2 | 4

Setting the I/O Base Address
1626
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1628
The first six switches in switch block SW1 are used to select the I/O Base
1629
address using the following table::
1631
Switch | Hex I/O
1632

1644
combinations are documented.
1647
Setting the Base Memory (RAM) buffer Address
1648
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1650
The switches 7-10 of switch block SW1 are used to select the Memory
1651
Base address of the RAM (2K) and the PROM::
1653
Switch | Hex RAM | Hex ROM
1654

1660
.. note::
1662
Other MEM-Base addresses seem to be selectable, but only the above
1663
combinations are documented.
1666
Setting the Interrupt Line
1667
^^^^^^^^^^^^^^^^^^^^^^^^^^
1669
To select a hardware interrupt level install one (only one!) of the jumpers
1670
JP3 through JP13 using the following table::
1672
Jumper | IRQ
1673
-------|-----------------
1674
3 | 14
1675
4 | 15
1676

1681
10 | 5
1682
11 | 6
1683
12 | 7
1684
13 | 2 (=9) Default!
1686
.. note::
1688
- Do not use JP11=IRQ6, it may conflict with your Floppy Disk
1689
Controller
1690
- Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
1691
Hard Disk, it may conflict with their controllers
1694
Setting the Timeout Parameters
1695
------------------------------
1697
The jumpers labeled JP1 and JP2 are used to determine the timeout
1698
parameters. These two jumpers are normally left open.

It seems that the bits are considered in reverse order. Also, you must
1756
observe that some of those addresses are unusual and I didn't probe them; I
1757
used a memory dump in DOS to identify them. For the 00000 configuration and
1758
some others that I didn't write here the card seems to conflict with the
1759
video card (an S3 GENDAC). I leave the full decoding of those addresses to
1760
you.

Setting the Node ID
1863
^^^^^^^^^^^^^^^^^^^
1865
The eight switches in SW2 are used to set the node ID. Each node attached
1866
to the network must have an unique node ID which must not be 0.
1867
Switch 1 (ID0) serves as the least significant bit (LSB).
1869
Setting one of the switches to OFF means "1", ON means "0".
1871
The node ID is the sum of the values of all switches set to "1"
1872
These values are::
1874
Switch | Value
1875
-------|-------
1876
1 | 1
1877
2 | 2
1878

5 | 16
1881
6 | 32
1882
7 | 64
1883
8 | 128
1885
Don't set this to 0 or 255; these values are reserved.
1888
Setting the I/O Base Address
1889
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1891
The switches 1 to 6 of switch block SW1 are used to select one
1892
of 32 possible I/O Base addresses using the following tables::
1894
| Hex
1895
Switch | Value
1896
-------|-------
1897
1 | 200
1898
2 | 100
1899
3 | 80
1900
4 | 40
1901
5 | 20
1902
6 | 10
1904
The I/O address is sum of all switches set to "1". Remember that
1905
the I/O address space below 0x200 is RESERVED for mainboard, so
1906
switch 1 should be ALWAYS SET TO OFF.
1909
Setting the Base Memory (RAM) buffer Address
1910
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1912
The memory buffer (RAM) requires 2K. The base of this buffer can be
1913
located in any of sixteen positions. However, the addresses below
1914
A0000 are likely to cause system hang because there's main RAM.
1916
Jumpers 7-10 of switch block SW1 select the Memory Base address::
1918
Switch | Hex RAM
1919
7 8 9 10 | Address
1920
----------------|---------
1921
OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
1922
OFF OFF OFF ON | E0000
1923
OFF OFF ON OFF | D0000
1924
OFF OFF ON ON | C0000 (conflicts with video BIOS)
1925
OFF ON OFF OFF | B0000 (conflicts with mono video)
1926
OFF ON OFF ON | A0000 (conflicts with graphics)
1929
Setting the Interrupt Line
1930
^^^^^^^^^^^^^^^^^^^^^^^^^^
1932
Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
1933
shorted, OFF means open::
1935
Jumper | IRQ
1936
1 2 3 4 5 |
1937
----------------------------
1938
ON OFF OFF OFF OFF | 7
1939
OFF ON OFF OFF OFF | 5
1940
OFF OFF ON OFF OFF | 4
1941
OFF OFF OFF ON OFF | 3
1942
OFF OFF OFF OFF ON | 2
1945
Unknown jumpers & sockets
1946
^^^^^^^^^^^^^^^^^^^^^^^^^
1948
I know nothing about these. I just guess that J16&J17 are timeout
1949
jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
1950
J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
1951
guess the purpose.
1953

1961
This is another SMC 90C65-based ARCnet card. I couldn't identify the

2050
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2052
The memory buffer (RAM) requires 2K. The base of this buffer can be
2053
located in any of eight positions. The address of the Boot Prom is
2054
memory base + 0x2000.
2056

Setting the Node ID
2153
^^^^^^^^^^^^^^^^^^^
2155
The eight switches in SW2 are used to set the node ID. Each node attached to
2156
the network must have an unique node ID which must not be 0. Switch 1 (ID0)
2157
serves as the least significant bit (LSB).
2159
Setting one of the switches to Off means "1", On means "0".
2161
The node ID is the sum of the values of all switches set to "1"
2162
These values are::
2164
Switch | Label | Value
2165
-------|-------|-------
2166
1 | ID0 | 1
2167
2 | ID1 | 2

8 | ID7 | 128
2175
Setting the I/O Base Address
2176
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2178
The last three switches in switch block SW1 are used to select one
2179
of eight possible I/O Base addresses using the following table::
2182
Switch | Hex I/O
2183
6 7 8 | Address
2184
------------|--------
2185
ON ON ON | 260 (Manufacturer's default)

ON ON OFF | 300
2190
OFF ON OFF | 350
2191
ON OFF OFF | 380
2192
OFF OFF OFF | 3E0
2195
Setting the Base Memory (RAM) buffer Address
2196
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2198
The memory buffer (RAM) requires 2K. The base of this buffer can be
2199
located in any of eight positions. The address of the Boot Prom is
2200
memory base + 0x2000.
2202
Jumpers 3-5 of switch block SW1 select the Memory Base address.

2218
*) To enable the Boot ROM short the jumper J2.
2220
The jumpers 1 and 2 probably add 0x0800 and 0x1000 to RAM address.
2223
Setting the Interrupt Line
2224
^^^^^^^^^^^^^^^^^^^^^^^^^^
2226
Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
2227
shorted, OFF means open::
2229

2239
Setting the Timeout Parameters
2240
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2242
The jumpers J3 are used to set the timeout parameters. These two
2243
jumpers are normally left open.

There is a DIP-switch with 8 switches, used to set the shared memory address
2324
to be used. The first 6 switches set the address, the 7th doesn't have any
2325
function, and the 8th switch is used to select "compatible" or "enhanced".
2326
When I got my two cards, one of them had this switch set to "enhanced". That
2327
card didn't work at all, it wasn't even recognized by the driver. The other
2328
card had this switch set to "compatible" and it behaved absolutely normally. I
2329
guess that the switch on one of the cards, must have been changed accidentally
2330
when the card was taken out of its former host. The question remains
2331
unanswered, what is the purpose of the "enhanced" position?
2333
[Avery's note: "enhanced" probably either disables shared memory (use IO
2334
ports instead) or disables IO ports (use memory addresses instead). This
2335
varies by the type of card involved. I fail to see how either of these
2336
enhance anything. Send me more detailed information about this mode, or
2337
just use "compatible" mode instead.]

- from Robert Michael Best <[email protected]>
2346
[Avery's note: these don't work with my driver for some reason. These cards
2347
SEEM to have settings similar to the PDI508Plus, which is
2348
software-configured and doesn't work with my driver either. The "Waterloo
2349
chip" is a boot PROM, probably designed specifically for the University of
2350
Waterloo. If you have any further information about this card, please
2351
e-mail me.]
2353
The probe has not been able to detect the card on any of the J2 settings,
2354
and I tried them again with the "Waterloo" chip removed.

I have named this ARCnet card "NONAME", since there is no name of any
2455
manufacturer on the Installation manual nor on the shipping box. The only
2456
hint to the existence of a manufacturer at all is written in copper,
2457
it is "Made in Taiwan"

Setting the Node ID
2508
^^^^^^^^^^^^^^^^^^^
2510
The eight switches in group SW1 are used to set the node ID.
2511
Each node attached to the network must have an unique node ID which
2512
must be different from 0.
2513
Switch 8 serves as the least significant bit (LSB).
2515
The node ID is the sum of the values of all switches set to "1"
2516
These values are::
2518

Setting the I/O Base Address
2549
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2551
The first three switches in switch group SW2 are used to select one
2552
of eight possible I/O Base addresses using the following table::
2554
Switch | Hex I/O
2555
1 2 3 | Address
2556
------------|--------
2557
ON ON ON | 260

2567
Setting the Base Memory (RAM) buffer Address
2568
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2570
The memory buffer requires 2K of a 16K block of RAM. The base of this
2571
16K block can be located in any of eight positions.
2572
Switches 4-6 of switch group SW2 select the Base of the 16K block.
2573
Within that 16K address space, the buffer may be assigned any one of four
2574
positions, determined by the offset, switches 7 and 8 of group SW2.

*) To enable the 8K Boot PROM install the jumper ROM.
2622
The default is jumper ROM not installed.
2625
Setting Interrupt Request Lines (IRQ)
2626
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2628
To select a hardware interrupt level set one (only one!) of the jumpers
2629
IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
2632
Setting the Timeouts
2633
^^^^^^^^^^^^^^^^^^^^
2635
The two jumpers labeled ET1 and ET2 are used to determine the timeout
2636
parameters (response and reconfiguration time). Every node in a network
2637
must be set to the same timeout values.
2639
::
2641
ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
2642
--------|--------------------|--------------------------
2643
Off Off | 78 | 840 (Default)
2644
Off On | 285 | 1680
2645
On Off | 563 | 1680
2646
On On | 1130 | 1680
2648

16-BIT ARCNET
2652
-------------
2654
The manual of my 8-Bit NONAME ARCnet Card contains another description
2655
of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
2656
because there are missing two pages in the manual booklet. (The table
2657
of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
2658
the booklet there is a different way of counting ... 2-9, 2-10, A-1,
2659
(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
2660
Also the picture of the board layout is not as good as the picture of
2661
8-Bit card, because there isn't any letter like "SW1" written to the
2662
picture.
2664
Should somebody have such a board, please feel free to complete this
2665
description or to send a mail to me!

Setting one of the switches to Off means "1", On means "0".
2703
Setting the Node ID
2704
^^^^^^^^^^^^^^^^^^^
2706
The eight switches in group SW2 are used to set the node ID.
2707
Each node attached to the network must have an unique node ID which
2708
must be different from 0.
2709
Switch 8 serves as the least significant bit (LSB).
2711
The node ID is the sum of the values of all switches set to "1"
2712
These values are::
2714
Switch | Value
2715
-------|-------
2716
8 | 1
2717
7 | 2
2718
6 | 4

Setting the I/O Base Address
2745
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2747
The first three switches in switch group SW1 are used to select one
2748
of eight possible I/O Base addresses using the following table::
2750
Switch | Hex I/O
2751

2763
Setting the Base Memory (RAM) buffer Address
2764
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2766
The memory buffer requires 2K of a 16K block of RAM. The base of this
2767
16K block can be located in any of eight positions.
2768
Switches 6-8 of switch group SW1 select the Base of the 16K block.
2769
Within that 16K address space, the buffer may be assigned any one of four
2770
positions, determined by the offset, switches 4 and 5 of group SW1::
2772

8-bit cards ("Made in Taiwan R.O.C.")
2829
-------------------------------------
2831
- from Vojtech Pavlik <[email protected]>
2833
I have named this ARCnet card "NONAME", since I got only the card with
2834
no manual at all and the only text identifying the manufacturer is
2835
"MADE IN TAIWAN R.O.C" printed on the card.

Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
2877
switches.
2879
Setting the jumpers to ON means connecting the upper two pins, off the bottom
2880
two - or - in case of IRQ setting, connecting none of them at all.
2882
Setting the Node ID
2883
^^^^^^^^^^^^^^^^^^^
2885
The eight switches in SW2 are used to set the node ID. Each node attached
2886
to the network must have an unique node ID which must not be 0.
2887
Switch 1 (ID0) serves as the least significant bit (LSB).
2889
Setting one of the switches to Off means "1", On means "0".
2891
The node ID is the sum of the values of all switches set to "1"
2892
These values are::
2894
Switch | Label | Value
2895
-------|-------|-------
2896
1 | ID0 | 1
2897

Setting the I/O Base Address
2925
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2927
The last three switches in switch block SW1 are used to select one
2928
of eight possible I/O Base addresses using the following table::
2931
Switch | Hex I/O
2932

2944
Setting the Base Memory (RAM) buffer Address
2945
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2947
The memory buffer (RAM) requires 2K. The base of this buffer can be
2948
located in any of eight positions. The address of the Boot Prom is
2949
memory base + 0x2000.
2951
Jumpers 3-5 of jumper block SW1 select the Memory Base address.

2969
The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
2971
Setting the Interrupt Line
2972
^^^^^^^^^^^^^^^^^^^^^^^^^^
2974
Jumpers 1-5 of the jumper block SW3 control the IRQ level::

SW1: Timeouts, Interrupt and ROM
3048
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3050
To select a hardware interrupt level set one (only one!) of the dip switches
3051
up (on) SW1...(switches 1-5)
3052
IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
3054
The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
3055
are used to determine the timeout parameters. These two dip switches
3056
are normally left off (down).
3058
To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
3059
The default is jumper ROM not installed.
3062
Setting the I/O Base Address
3063
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3065
The last three switches in switch group SW2 are used to select one
3066
of eight possible I/O Base addresses using the following table::
3069
Switch | Hex I/O
3070

Setting the Base Memory Address (RAM & ROM)
3083
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3085
The memory buffer requires 2K of a 16K block of RAM. The base of this
3086
16K block can be located in any of eight positions.
3087
Switches 1-3 of switch group SW2 select the Base of the 16K block.

Setting the Node ID
3108
^^^^^^^^^^^^^^^^^^^
3110
The eight switches in group SW3 are used to set the node ID.
3111
Each node attached to the network must have an unique node ID which
3112
must be different from 0.
3113
Switch 1 serves as the least significant bit (LSB).
3114
switches in the DOWN position are OFF (0) and in the UP position are ON (1)

ARCnet 소개
21-81ARCnet 소개
ARCnet은 널리 쓰이는 Ethernet과 비슷하게 동작하지만 몇 가지 매우 중요한 차이가 있는 network 형식입니다.
ARCnet card는 적어도 2.5 Mbps와 100 Mbps 두 속도로 나옵니다. 다른 속도도 있지만 덜 흔합니다. 서로 다른 hardware 형식은 호환되지 않으므로 100 Mbps card와 2.5 Mbps card를 직접 연결할 수 없습니다. 작성자의 driver가 100 Mbps card에서도 동작한다는 보고는 있었지만 작성자는 2.5 Mbps card만 보유해 직접 검증하지 못했고, 100 Mbps를 포화시킬 가능성도 낮다고 설명합니다.
ARCnet card를 어떤 Ethernet card와 연결해도 동작하지 않습니다.
ARCnet에는 배선 방식에 따라 STAR topology와 BUS topology 두 형식이 있습니다. 일반 문서는 STAR card끼리, BUS card끼리만 연결할 수 있다고 설명하지만 실제로는 배선 절에서 설명하는 예외가 있습니다.
ARCnet은 `modified token passing`을 사용합니다. 이름이 비슷한 Token Ring card와는 완전히 호환되지 않지만 Ethernet보다 전송 신뢰성이 높습니다. 패킷이 목적지에 안전하게 도착함을 보장하고, cable 단선이나 없는 목적지처럼 전달할 수 없는 경우에도 적어도 sender에게 실패를 알립니다.
Token의 동작 시간이 세밀하게 정의되어 있어 token이 정해진 최대 시간 안에 ring을 한 바퀴 돌며, 이 특성은 realtime network에 유용합니다.
알려진 ARCnet card는 거의 동일한 programming interface를 사용하므로 driver 하나로 여러 제조사의 card를 지원할 수 있습니다. Ethernet은 제조사마다 interface가 크게 달라 비슷한 driver가 많이 필요합니다. 반면 공통 interface를 고수하면 PCI bus-mastering DMA 같은 고성능 기능이 나왔을 때 이를 활용하기 어렵습니다.
표준 ARCnet 패킷은 최대 508 byte로 제한되어 Internet의 최소 576 byte와 Ethernet MTU 1500보다 작습니다. 이를 보완하기 위해 RFC 1201은 문서에서 `packet splitting`이라 부르는 추가 encapsulation 계층을 정의합니다. 가상 패킷은 최대 64 KiB까지 커질 수 있지만 일반적으로 Ethernet과 같은 1500 byte로 유지합니다.
ARCnet 장단점에 관한 당시 자료로 ARCnet Trade Association의 `http://www.arcnet.com`을 제시합니다.
Introduction to ARCnet
======================
ARCnet is a network type which works in a way similar to popular Ethernet
networks but which is also different in some very important ways.
First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
(slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
there are others as well, but these are less common. The different hardware
types, as far as I'm aware, are not compatible and so you cannot wire a
100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
work with 100 Mbps cards, but I haven't been able to verify this myself,
since I only have the 2.5 Mbps variety. It is probably not going to saturate
your 100 Mbps card. Stop complaining. :)
You also cannot connect an ARCnet card to any kind of Ethernet card and
expect it to work.
There are two "types" of ARCnet - STAR topology and BUS topology. This
refers to how the cards are meant to be wired together. According to most
available documentation, you can only connect STAR cards to STAR cards and
BUS cards to BUS cards. That makes sense, right? Well, it's not quite
true; see below under "Cabling."
Once you get past these little stumbling blocks, ARCnet is actually quite a
well-designed standard. It uses something called "modified token passing"
which makes it completely incompatible with so-called "Token Ring" cards,
but which makes transfers much more reliable than Ethernet does. In fact,
ARCnet will guarantee that a packet arrives safely at the destination, and
even if it can't possibly be delivered properly (ie. because of a cable
break, or because the destination computer does not exist) it will at least
tell the sender about it.
Because of the carefully defined action of the "token", it will always make
a pass around the "ring" within a maximum length of time. This makes it
useful for realtime networks.
In addition, all known ARCnet cards have an (almost) identical programming
interface. This means that with one ARCnet driver you can support any
card, whereas with Ethernet each manufacturer uses what is sometimes a
completely different programming interface, leading to a lot of different,
sometimes very similar, Ethernet drivers. Of course, always using the same
programming interface also means that when high-performance hardware
facilities like PCI bus mastering DMA appear, it's hard to take advantage of
them. Let's not go into that.
One thing that makes ARCnet cards difficult to program for, however, is the
limit on their packet sizes; standard ARCnet can only send packets that are
up to 508 bytes in length. This is smaller than the Internet "bare minimum"
of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
level of encapsulation is defined by RFC1201, which I call "packet
splitting," that allows "virtual packets" to grow as large as 64K each,
although they are generally kept down to the Ethernet-style 1500 bytes.

advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

ARCnet network 배선
82-262ARCnet network 배선
이 절은 Vojtech Pavlik이 Avery Pennraun, Stephen A. Wood, John Paul Morrison, Joachim Koenig 등의 정보를 바탕으로 다시 작성했고 Avery가 다듬었습니다.
고전적인 2.5 Mbps ARCnet은 coax와 twisted pair 두 배선 형식을 사용할 수 있습니다. 100 Mbps TCNS와 320 kbps~32 Mbps ARCnet Plus 같은 다른 ARCnet 계열 network는 Type 1, fiber, C1, C4, C5 등 다른 cable을 사용합니다.
Coax network에는 원칙적으로 93 Ohm RG-62 cable을 사용해야 하지만 ARCnet은 안정적이어서 다른 cable도 동작할 수 있습니다. 작성자는 75 Ohm TV antenna cable을 사용했습니다.
Coax용 card는 BUS와 STAR topology variant로 나옵니다. 대부분 같고 설치된 hybrid chip만 다릅니다. BUS card는 high-impedance output을, STAR card는 low-impedance output을 사용합니다. STAR의 low-impedance card는 terminator를 설치한 BUS high-impedance card와 전기적으로 같습니다.
일반적으로 ARCnet network는 STAR card와 hub로 구성합니다. Passive hub는 BNC connector 네 개와 47 Ohm resistor 네 개를 junction에 연결한 작은 box이며 shield는 서로 연결됩니다. Active hub는 전원을 사용하고 signal을 증폭해 다른 segment로 보내는 전자 회로가 있으며 보통 connector 여덟 개를 가집니다.
Active hub에는 dumb와 smart variant가 있습니다. Dumb hub는 증폭만 하고 smart hub는 통과하는 모든 packet을 digital로 decode한 뒤 다시 encode합니다. Dumb active hub를 여러 개 쓰면 signal 품질이 나빠질 수 있어 hub가 많은 network에는 smart 방식이 더 좋습니다.
연결 가능한 조합은 다음과 같습니다.
- Card와 card: computer 두 대 network를 만드는 가장 단순한 방법입니다.
- Card와 passive hub: 사용하지 않는 hub connector를 93 Ohm terminator로 올바르게 종단해야 합니다. 정확한 부품이 없으면 다른 terminator도 동작할 수 있습니다.
- Card와 active hub: 사용하지 않는 connector는 종단할 필요가 없습니다. 두 computer 사이에는 active hub를 최대 11개까지만 둘 수 있지만 network 전체 active hub 수를 제한하는 것은 아닙니다.
- Active hub와 다른 active hub를 연결할 수 있습니다.
- Active hub와 passive hub를 연결할 수 있습니다.
Passive hub 두 개를 직접 연결하면 power loss가 너무 커 network를 안정적으로 운용할 수 없으므로 연결하면 안 됩니다.
BUS topology는 Ethernet과 비슷하지만 cable과 terminator가 93 Ohm이어야 합니다. Ethernet은 50 Ohm을 사용합니다. T connector로 computer를 한 줄의 bus cable에 붙이고 cable 양 끝을 terminator로 종단합니다.
공식 문서는 STAR와 BUS를 active hub로 연결하거나 BUS 끝의 BUS card+terminator 대신 STAR card를 쓰도록 설명합니다. 작성자의 실험에서는 STAR topology cable 중간에 BUS card를 매달 수 있었고 terminator를 함께 사용하면 BUS card를 STAR card 대신 쓸 수도 있었습니다.
Twisted-pair 배선은 방식이 다릅니다. TP card마다 RJ connector 두 개가 있고 이웃한 card끼리 cable로 daisy chain을 만듭니다. Chain 양 끝 card의 빈 connector에는 RJ 93 Ohm terminator를 꽂습니다.
TP topology에도 hub가 있으며 TP chain의 한쪽 끝이나 양쪽 끝을 hub에 연결해 거의 모든 구성을 만들 수 있습니다. 이 경우에도 두 computer 사이 hub 최대 11개 규칙이 적용됩니다.
Network cable 길이에는 한계가 있습니다. Active hub나 STAR card처럼 두 active end 사이의 최대 길이는 RG-62 93 Ohm 650 m, RG-59/U 75 Ohm 457 m, RG-11/U 75 Ohm 533 m, IBM Type 1 150 Ohm 200 m, IBM Type 3 100 Ohm 100 m입니다.
Passive hub에 연결된 모든 cable의 총 길이는 RG-62에서 65 m이며 다른 cable은 더 짧습니다. 큰 network에서 passive hub는 좋지 않습니다. RG-62 단일 BUS trunk는 약 300 m, network 최원점 간 거리는 3000 m, card·hub 사이 TP cable은 650 m가 최대입니다.
Cabling ARCnet Networks
=======================
This section was rewritten by
Vojtech Pavlik <[email protected]>
using information from several people, including:
- Avery Pennraun <[email protected]>
- Stephen A. Wood <[email protected]>
- John Paul Morrison <[email protected]>
- Joachim Koenig <[email protected]>
and Avery touched it up a bit, at Vojtech's request.
ARCnet (the classic 2.5 Mbps version) can be connected by two different
types of cabling: coax and twisted pair. The other ARCnet-type networks
(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
cabling (Type1, Fiber, C1, C4, C5).
For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
also work fine, because ARCnet is a very stable network. I personally use 75
Ohm TV antenna cable.
Cards for coax cabling are shipped in two different variants: for BUS and
STAR network topologies. They are mostly the same. The only difference
lies in the hybrid chip installed. BUS cards use high impedance output,
while STAR use low impedance. Low impedance card (STAR) is electrically
equal to a high impedance one with a terminator installed.
Usually, the ARCnet networks are built up from STAR cards and hubs. There
are two types of hubs - active and passive. Passive hubs are small boxes
with four BNC connectors containing four 47 Ohm resistors::
| | wires
R + junction
-R-+-R- R 47 Ohm resistors
R
|
The shielding is connected together. Active hubs are much more complicated;
they are powered and contain electronics to amplify the signal and send it
to other segments of the net. They usually have eight connectors. Active
hubs come in two variants - dumb and smart. The dumb variant just
amplifies, but the smart one decodes to digital and encodes back all packets
coming through. This is much better if you have several hubs in the net,
since many dumb active hubs may worsen the signal quality.
And now to the cabling. What you can connect together:
1. A card to a card. This is the simplest way of creating a 2-computer
network.
2. A card to a passive hub. Remember that all unused connectors on the hub
must be properly terminated with 93 Ohm (or something else if you don't
have the right ones) terminators.
(Avery's note: oops, I didn't know that. Mine (TV cable) works
anyway, though.)
3. A card to an active hub. Here is no need to terminate the unused
connectors except some kind of aesthetic feeling. But, there may not be
more than eleven active hubs between any two computers. That of course
doesn't limit the number of active hubs on the network.
4. An active hub to another.
5. An active hub to passive hub.
Remember that you cannot connect two passive hubs together. The power loss
implied by such a connection is too high for the net to operate reliably.
An example of a typical ARCnet network::
R S - STAR type card
S------H--------A-------S R - Terminator
| | H - Hub
| | A - Active hub
| S----H----S
S |
|
S
The BUS topology is very similar to the one used by Ethernet. The only
difference is in cable and terminators: they should be 93 Ohm. Ethernet
uses 50 Ohm impedance. You use T connectors to put the computers on a single
line of cable, the bus. You have to put terminators at both ends of the
cable. A typical BUS ARCnet network looks like::
RT----T------T------T------T------TR
B B B B B B
B - BUS type card
R - Terminator
T - T connector
But that is not all! The two types can be connected together. According to
the official documentation the only way of connecting them is using an active
hub::
A------T------T------TR
| B B B
S---H---S
|
S
The official docs also state that you can use STAR cards at the ends of
BUS network in place of a BUS card and a terminator::
S------T------T------S
B B
But, according to my own experiments, you can simply hang a BUS type card
anywhere in middle of a cable in a STAR topology network. And more - you
can use the bus card in place of any star card if you use a terminator. Then
you can build very complicated networks fulfilling all your needs! An
example::
S
|
RT------T-------T------H------S
B B B |
| R
S------A------T-------T-------A-------H------TR
| B B | | B
| S BT |
| | | S----A-----S
S------H---A----S | |
| | S------T----H---S |
S S B R S
A basically different cabling scheme is used with Twisted Pair cabling. Each
of the TP cards has two RJ (phone-cord style) connectors. The cards are
then daisy-chained together using a cable connecting every two neighboring
cards. The ends are terminated with RJ 93 Ohm terminators which plug into
the empty connectors of cards on the ends of the chain. An example::
___________ ___________
_R_|_ _|_|_ _|_R_
| | | | | |
|Card | |Card | |Card |
|_____| |_____| |_____|
There are also hubs for the TP topology. There is nothing difficult
involved in using them; you just connect a TP chain to a hub on any end or
even at both. This way you can create almost any network configuration.
The maximum of 11 hubs between any two computers on the net applies here as
well. An example::
RP-------P--------P--------H-----P------P-----PR
|
RP-----H--------P--------H-----P------PR
| |
PR PR
R - RJ Terminator
P - TP Card
H - TP Hub
Like any network, ARCnet has a limited cable length. These are the maximum
cable lengths between two active ends (an active end being an active hub or
a STAR card).
========== ======= ===========
RG-62 93 Ohm up to 650 m
RG-59/U 75 Ohm up to 457 m
RG-11/U 75 Ohm up to 533 m
IBM Type 1 150 Ohm up to 200 m
IBM Type 3 100 Ohm up to 100 m
========== ======= ===========
The maximum length of all cables connected to a passive hub is limited to 65
meters for RG-62 cabling; less for others. You can see that using passive
hubs in a large network is a bad idea. The maximum length of a single "BUS
Trunk" is about 300 meters for RG-62. The maximum distance between the two
most distant points of the net is limited to 3000 meters. The maximum length
of a TP cable between two cards/hubs is 650 meters.
일반 jumper 설정
263-444Jumper 설정
ARCnet card에는 일반적으로 I/O address, IRQ, shared-memory address, station address, 선택적으로 ETS1·ETS2라는 네다섯 종류 설정이 있습니다.
I/O address는 ARCnet card의 port입니다. Linux ARCnet driver가 probe하는 범위는 0x200~0x3F0이며 다른 system device와 겹치면 안 됩니다. Novell 문서는 MS Windows가 0x300 이상을 선호한다고 설명합니다. 예를 들어 card가 0x2E0이면 0x2E8 serial port probe가 card를 reset할 수 있습니다. 작성자가 선호한 값은 0x300입니다.
IRQ는 8-bit card에서 2(9), 3, 4, 5, 7일 수 있고 16-bit card에서는 여기에 10~15가 추가될 수 있습니다. 다른 card와 겹치면 안 됩니다. Linux에서는 IRQ2와 IRQ9가 같으며 `/proc/interrupts`에서 현재 사용 상태를 확인할 수 있습니다.
당시 일반 용도는 IRQ0 timer, IRQ1 keyboard, IRQ2 second IRQ controller, IRQ3 COM2, IRQ4 COM1, IRQ5 여유(LPT2·COM3·PLIP 가능), IRQ6 floppy, IRQ7 여유(LPT1·PLIP 가능), IRQ8 realtime clock, IRQ9 대체로 여유(VGA vertical sync 가능), IRQ10~12 여유, IRQ13 numeric coprocessor, IRQ14 fixed disk, IRQ15 여유 또는 두 번째 fixed disk였습니다. `Not on bus`인 interrupt는 card가 생성할 수 없습니다.
일부 video card는 IRQ9를 vertical retrace interrupt로 사용하지만 원래 VGA부터 이 기능이 취소되어 modern software는 거의 사용하지 않습니다. 지원된다면 대체로 안전하게 끌 수 있습니다. 문서는 비활성화할 수 없는 card의 board contact를 자르는 극단적 방법도 언급하지만 결과에 책임지지 않는다고 명시합니다. 작성자가 선호한 IRQ는 IRQ2, 즉 IRQ9였습니다.
ARCnet은 buffer copy에 shared memory를 사용합니다. 다른 system memory와 충돌하지 않아야 합니다. A0000은 VGA graphics, B0000은 monochrome text, C0000 또는 E0000 중 하나는 보통 VGA BIOS, F0000은 system BIOS입니다. 0xA0000 아래는 640 KiB 아래이므로 피해야 하며 작성자가 선호한 값은 0xD0000입니다.
각 ARCnet card는 0~255의 network station address를 jumper·switch 또는 일부 card에서는 software로 설정합니다. 8 bit이므로 network에는 최대 254개 card를 둘 수 있습니다. 0과 255는 reserved이므로 사용하지 말고 다른 card와 중복해서도 안 됩니다.
ETS1·ETS2는 computer가 network에서 켜질 때 사용하는 delay를 바꾸며 약 4 km의 매우 긴 ARCnet network에서만 필요합니다. Open/open은 response 74.7 us와 reconfiguration 840 us, open/closed는 283.4 us·1680 us, closed/open은 561.8 us·1680 us, closed/closed는 1118.6 us·1680 us입니다. Network의 모든 card에서 두 jumper 위치를 같게 해야 합니다.
LED 상태는 green/red가 모두 off면 전원 꺼짐, green off와 red 짧은 flash면 cable 단선·미종단, green 짧게 off와 red on이면 card 초기화, 둘 다 on이면 정상 idle, green on과 red 긴 flash면 data transfer, green on과 red off는 보통 발생하지 않으며 잘못된 ID일 수 있습니다.
이어지는 card별 정보는 여러 사람이 보낸 자료를 그대로 모아 중복과 불확실성이 많습니다. Model 번호로 검색하거나 board diagram을 비교해 card를 식별해야 합니다. 목록에는 SMC PC100·110·120·130·270E·500·550·600·710, LCS-8830, PureData PDI507, CNet CN120·CN160, Lantech UM9065L, Acer 5210-003, LAN-ARC-8, Topware TA-ARC/10, Thomas-Conrad 500-6242-0097, Waterloo, 여러 무명 card, model 9058, Tiara 등이 포함됩니다.
Setting the Jumpers
===================
All ARCnet cards should have a total of four or five different settings:
- the I/O address: this is the "port" your ARCnet card is on. Probed
values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
your card has additional ones, which is possible, please tell me.) This
should not be the same as any other device on your system. According to
a doc I got from Novell, MS Windows prefers values of 0x300 or more,
eating net connections on my system (at least) otherwise. My guess is
this may be because, if your card is at 0x2E0, probing for a serial port
at 0x2E8 will reset the card and probably mess things up royally.
- Avery's favourite: 0x300.
- the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
Make sure this is different from any other card on your system. Note
that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
"cat /proc/interrupts" for a somewhat complete list of which ones are in
use at any given time. Here is a list of common usages from Vojtech
Pavlik <[email protected]>:
("Not on bus" means there is no way for a card to generate this
interrupt)
====== =========================================================
IRQ 0 Timer 0 (Not on bus)
IRQ 1 Keyboard (Not on bus)
IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
IRQ 3 COM2
IRQ 4 COM1
IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
IRQ 6 Floppy disk controller
IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP)
IRQ 8 Realtime Clock Interrupt (Not on bus)
IRQ 9 FREE (VGA vertical sync interrupt if enabled)
IRQ 10 FREE
IRQ 11 FREE
IRQ 12 FREE
IRQ 13 Numeric Coprocessor (Not on bus)
IRQ 14 Fixed Disk Controller
IRQ 15 FREE (Fixed Disk Controller 2 if you have it)
====== =========================================================
.. note::
IRQ 9 is used on some video cards for the "vertical retrace"
interrupt. This interrupt would have been handy for things like
video games, as it occurs exactly once per screen refresh, but
unfortunately IBM cancelled this feature starting with the original
VGA and thus many VGA/SVGA cards do not support it. For this
reason, no modern software uses this interrupt and it can almost
always be safely disabled, if your video card supports it at all.
If your card for some reason CANNOT disable this IRQ (usually there
is a jumper), one solution would be to clip the printed circuit
contact on the board: it's the fourth contact from the left on the
back side. I take no responsibility if you try this.
- Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
- the memory address: Unlike most cards, ARCnets use "shared memory" for
copying buffers around. Make SURE it doesn't conflict with any other
used memory in your system!
::
A0000 - VGA graphics memory (ok if you don't have VGA)
B0000 - Monochrome text mode
C0000 \ One of these is your VGA BIOS - usually C0000.
E0000 /
F0000 - System BIOS
Anything less than 0xA0000 is, well, a BAD idea since it isn't above
640k.
- Avery's favourite: 0xD0000
- the station address: Every ARCnet card has its own "unique" network
address from 0 to 255. Unlike Ethernet, you can set this address
yourself with a jumper or switch (or on some cards, with special
software). Since it's only 8 bits, you can only have 254 ARCnet cards
on a network. DON'T use 0 or 255, since these are reserved (although
neat stuff will probably happen if you DO use them). By the way, if you
haven't already guessed, don't set this the same as any other ARCnet on
your network!
- Avery's favourite: 3 and 4. Not that it matters.
- There may be ETS1 and ETS2 settings. These may or may not make a
difference on your card (many manuals call them "reserved"), but are
used to change the delays used when powering up a computer on the
network. This is only necessary when wiring VERY long range ARCnet
networks, on the order of 4km or so; in any case, the only real
requirement here is that all cards on the network with ETS1 and ETS2
jumpers have them in the same position. Chris Hindy <[email protected]>
sent in a chart with actual values for this:
======= ======= =============== ====================
ET1 ET2 Response Time Reconfiguration Time
======= ======= =============== ====================
open open 74.7us 840us
open closed 283.4us 1680us
closed open 561.8us 1680us
closed closed 1118.6us 1680us
======= ======= =============== ====================
Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
network.
Also, on many cards (not mine, though) there are red and green LED's.
Vojtech Pavlik <[email protected]> tells me this is what they mean:
=============== =============== =====================================
GREEN RED Status
=============== =============== =====================================
OFF OFF Power off
OFF Short flashes Cabling problems (broken cable or not
terminated)
OFF (short) ON Card init
ON ON Normal state - everything OK, nothing
happens
ON Long flashes Data transfer
ON OFF Never happens (maybe when wrong ID)
=============== =============== =====================================
The following is all the specific information people have sent me about
their own particular ARCnet cards. It is officially a mess, and contains
huge amounts of duplicated information. I have no time to fix it. If you
want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
The model # is listed right above specifics for that card, so you should be
able to use your text viewer's "search" function to find the entry you want.
If you don't KNOW what kind of card you have, try looking through the
various diagrams to see if you can tell.
If your model isn't listed and/or has different settings, PLEASE PLEASE
tell me. I had to figure mine out without the manual, and it WASN'T FUN!
Even if your ARCnet model isn't listed, but has the same jumpers as another
model that is, please e-mail me to say so.

cable-connector and it's for changing to star or bus topology;
closed: star - open: bus
On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI
and another with ALE,LA17,LA18,LA19 these are undocumented..

PC100·PC110·PC120·PC130 8-bit card와 PC500·PC600 16-bit card
주요 자료는 Avery Pennarun의 설정에서 왔습니다. Timo Hilbrink는 PC120·130·500·600이 PC100과 같은 switch를 쓴다고 확인했고, PC500·600에는 문서화되지 않은 pin이 더 있습니다. PC110 설정은 Stephen A. Wood가 검증했습니다. 실제 card의 JP·S 번호는 다를 수 있으므로 설정 수가 같은 switch를 찾는 편이 더 신뢰할 만합니다.
`JP5`는 IRQ2·3·4·5·7 중 하나를 고르며 정확히 한 pin pair에 jumper 하나만 설치합니다.
`S1`의 두 bit `a`는 I/O address 첫 hex digit 0~3, 네 bit `b`는 둘째 digit 0~F를 정해 `ab0` 형식을 만듭니다. 예를 들어 a=2, b=E이면 0x2E0입니다. 0x200보다 낮게 설정하면 안 됩니다. Card를 잡은 방향과 switch의 1 방향을 잘못 해석하기 쉬우므로 동작하지 않으면 방향을 뒤집거나 switch 의미를 반대로 확인해야 합니다.
`S1`의 네 bit `m`은 memory address 첫 digit을 정해 `m0000` 형식을 만듭니다. m=D이면 0xD0000입니다. C0000, F0000 또는 A0000 아래로 설정하면 안 됩니다.
`S2`의 8 bit는 station address를 정하며 binary digit 순서가 반대입니다. 00000000은 00, 10000000은 01, 01111111은 FE, 11111111은 FF입니다. 0과 255를 사용하면 안 됩니다.

Juergen Seifert가 SMC manual `Configuration Guide for ARCNET-PC130E/PC270 Network Controller Boards`, publication 900.044A, 1989년 6월판을 바탕으로 작성했습니다. ARCNET은 Datapoint, SMC는 Standard Microsystems의 registered trademark입니다.
PC130E는 PC130의 개선형으로 RG-62/U coax용 BNC female connector가 있습니다. STAR point-to-point와 BUS 모두를 지원하므로 PC120·110·100 STAR card와 PC220·210·200 BUS card 등 표준 coax board와 하위 호환됩니다. PC270E는 PC260 개선형으로 twisted pair용 RJ11 jack 두 개가 있으며 STAR 또는 daisy-chain network에 쓸 수 있습니다.
Board legend에서 S1 1~3은 I/O base, 4~6은 memory base, 7~8은 RAM offset을 정합니다. S2 1~8은 node ID입니다. EXT1·EXT2는 timeout, ROM은 boot ROM, STAR jumper는 PC130E topology, CR3·CR4는 LED, J1·J2는 model별 BNC 또는 telephone jack입니다. Switch OFF/open은 1, ON/closed는 0입니다.
S2 node ID는 PC100 series와 같은 방식입니다. S1 1~3의 I/O 선택은 260, 290, 2E0(제조사 기본), 2F0, 300, 350, 380, 3E0입니다.
Memory buffer는 16 KiB block 안의 2 KiB를 사용합니다. S1 4~6이 C0000부터 E0000 사이 16 KiB base를 선택하고 S1 7~8이 0x0000, 0x0800, 0x1000, 0x1800 offset을 고릅니다. 원문 표는 모든 RAM·ROM address 조합을 보존합니다. 8 KiB boot PROM은 `ROM` jumper를 설치해 켜며 기본은 미설치입니다.
EXT1·EXT2는 timeout을 정하고 보통 open입니다. IRQ2·3·4·5·7 중 정확히 하나를 선택하며 제조사 기본은 IRQ2입니다.
PC130E의 `STAR` jumper를 설치하면 STAR, 제거하면 BUS topology입니다.
Rear bracket의 green LED는 network activity를, red LED는 board activity를 표시합니다. Green on은 정상, blink는 reconfiguration, off는 board 결함 또는 node ID 0입니다. Red flash/on은 data transfer, off는 전송 없음 또는 잘못된 memory·I/O address입니다.

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in group S2 are used to set the node ID.
These switches work in a way similar to the PC100-series cards; see that
entry for more information.
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The first three switches in switch group S1 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
1 2 3 | Address
-------|--------
0 0 0 | 260
0 0 1 | 290
0 1 0 | 2E0 (Manufacturer's default)

1 1 0 | 380
1 1 1 | 3E0
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer requires 2K of a 16K block of RAM. The base of this
16K block can be located in any of eight positions.
Switches 4-6 of switch group S1 select the Base of the 16K block.
Within that 16K address space, the buffer may be assigned any one of four
positions, determined by the offset, switches 7 and 8 of group S1.

*) To enable the 8K Boot PROM install the jumper ROM.
The default is jumper ROM not installed.
Setting the Timeouts and Interrupt
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The jumpers labeled EXT1 and EXT2 are used to determine the timeout
parameters. These two jumpers are normally left open.
To select a hardware interrupt level set one (only one!) of the jumpers
IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
Configuring the PC130E for Star or Bus Topology
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The single jumper labeled STAR is used to configure the PC130E board for
star or bus topology.
When the jumper is installed, the board may be used in a star network, when
it is removed, the board can be used in a bus topology.
Diagnostic LEDs
^^^^^^^^^^^^^^^
Two diagnostic LEDs are visible on the rear bracket of the board.
The green LED monitors the network activity: the red one shows the
board activity::
Green | Status Red | Status
-------|------------------- ---------|-------------------
on | normal activity flash/on | data transfer
blink | reconfiguration off | no data transfer;
off | defective board or | incorrect memory or
| node ID is zero | I/O address
SMC PC500·PC550 longboard
757-983PC500·PC550 longboard 16-bit card
Juergen Seifert가 SMC publication 900.033 Rev. A, 1989년 11월판을 바탕으로 작성했습니다. PC500 short version은 hardware와 software가 다릅니다. Longboard에는 shared memory가 없고 interrupt를 binary-coded switch로 고르며, short board는 jumper로 직접 고릅니다.
Longboard에 shared memory가 없으므로 당시 Linux ARCnet driver는 이 card를 사용할 수 없었습니다. 작성자는 향후 실험할 계획이라고 기록했습니다.
PC500은 RG-62/U BNC를 사용하며 STAR point-to-point와 BUS를 지원합니다. PC550은 twisted pair용 RJ11 두 개를 사용하고 STAR 또는 daisy-chain BUS에 쓸 수 있습니다.
SW1 1~6은 I/O base, 7~10은 interrupt입니다. SW2 1~6은 reserved, SW3 1~8은 node ID, JP2는 timeout, JP6은 PC500 STAR/BUS, CR3·CR4는 LED입니다. OFF/open은 1, ON/closed는 0입니다.
SW3 node ID는 switch 1이 LSB이며 1·2·4·8·16·32·64·128 값을 합산합니다. 0은 허용하지 않습니다. 원문은 1~255의 예를 제공합니다.
SW1 1~6은 0x200~0x3F0의 32개 I/O base를 0x10 단위로 선택하며 제조사 기본은 0x2E0입니다.
SW1 7~10은 binary-coded IRQ를 정하며 지원값은 3, 4, 5, 7, 9(=2, 기본), 10, 11, 12입니다.
JP2의 두 jumper는 timeout을 정하고 보통 open입니다. 다른 값은 COM9026 data sheet를 참조합니다. PC500의 JP6을 설치하면 STAR, 제거하면 BUS입니다. LED 의미는 PC130E와 같습니다.
PC500/PC550 Longboard (16-bit cards)
------------------------------------
- from Juergen Seifert <[email protected]>
.. note::
There is another Version of the PC500 called Short Version, which
is different in hard- and software! The most important differences
are:
- The long board has no Shared memory.
- On the long board the selection of the interrupt is done by binary
coded switch, on the short board directly by jumper.
[Avery's note: pay special attention to that: the long board HAS NO SHARED
MEMORY. This means the current Linux-ARCnet driver can't use these cards.
I have obtained a PC500Longboard and will be doing some experiments on it in
the future, but don't hold your breath. Thanks again to Juergen Seifert for
his advice about this!]

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in group SW3 are used to set the node ID. Each node
attached to the network must have an unique node ID which must be
different from 0.
Switch 1 serves as the least significant bit (LSB).
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Value
-------|-------
1 | 1
2 | 2
3 | 4
4 | 8

Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The first six switches in switch group SW1 are used to select one
of 32 possible I/O Base addresses using the following table::
Switch | Hex I/O
6 5 4 3 2 1 | Address
-------------|--------
0 1 0 0 0 0 | 200

Setting the Interrupt
^^^^^^^^^^^^^^^^^^^^^
Switches seven through ten of switch group SW1 are used to select the
interrupt level. The interrupt level is binary coded, so selections
from 0 to 15 would be possible, but only the following eight values will
be supported: 3, 4, 5, 7, 9, 10, 11, 12.
::
Switch | IRQ
10 9 8 7 |
---------|--------
0 0 1 1 | 3
0 1 0 0 | 4
0 1 0 1 | 5
0 1 1 1 | 7
1 0 0 1 | 9 (=2) (default)
1 0 1 0 | 10
1 0 1 1 | 11
1 1 0 0 | 12
Setting the Timeouts
^^^^^^^^^^^^^^^^^^^^
The two jumpers JP2 (1-4) are used to determine the timeout parameters.
These two jumpers are normally left open.
Refer to the COM9026 Data Sheet for alternate configurations.
Configuring the PC500 for Star or Bus Topology
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The single jumper labeled JP6 is used to configure the PC500 board for
star or bus topology.
When the jumper is installed, the board may be used in a star network, when
it is removed, the board can be used in a bus topology.
Diagnostic LEDs
^^^^^^^^^^^^^^^
Two diagnostic LEDs are visible on the rear bracket of the board.
The green LED monitors the network activity: the red one shows the
board activity::
Green | Status Red | Status
-------|------------------- ---------|-------------------
on | normal activity flash/on | data transfer
blink | reconfiguration off | no data transfer;
off | defective board or | incorrect memory or

SMC PC710
984-1025PC710 8-bit card
J.S. van Oosten이 다른 card 정보와 실험으로 설정을 모았으며 99% 정도 맞다고 판단했습니다. SMC710은 PC270과 닮았지만 LED와 RJ11 jack이 없는 더 단순한 8-bit card입니다.
JP1의 8개 jumper는 위에서 아래로 EXT2, EXT1, ROM, IRQ7, IRQ5, IRQ4, IRQ3, IRQ2이며 PC270과 같습니다.
S1·S2 기능도 PC270과 같지만 번호가 서로 바뀌었습니다. S1은 node address, S2는 I/O·RAM address를 설정합니다. PC110 계열 ARCnet board와 연결해 동작함을 확인했습니다.

Note: this data is gathered by experimenting and looking at info of other
cards. However, I'm sure I got 99% of the settings right.
The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::

The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
S1 and S2 perform the same function as on the PC270, only their numbers
are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
I know it works when connected to a PC110 type ARCnet board.

LCS-8830(-T)
1026-1144제조사가 SMC일 가능성이 있는 LCS-8830(-T) 8·16-bit card
Mathias Katzer의 자료입니다. Marek Michalkiewicz에 따르면 LCS-8830은 LCS-8830-T와 조금 다르며 8-bit, BUS 전용, JP0 hardwired, BNC 전용입니다. 설명 대상 LCS-8830-T는 PLCC에만 SMC 표기가 있어 SMC 제품으로 추정됩니다.
SW1은 station address, SW2는 memory·I/O base입니다. JP0을 닫으면 internal termination, JP1은 IRQ, JP2는 boot ROM, JP3은 response timeout이고 U3는 boot ROM socket입니다.
ET1·ET2 open/open은 response 78, idle 86, reconfiguration 840이며 ET1만 closed는 285·316·1680, ET2만 closed는 563·624·1680, 둘 다 closed는 1130·1237·1680입니다. X는 closed jumper를 뜻하고 DIP switch 아래쪽은 0입니다.
Station address는 SW1 binary code입니다. SW2 6~8은 I/O base 260, 290, 2E0, 2F0, 300, 350, 380, 3E0을 고릅니다.
SW2 1~5는 RAM·ROM address range를 정합니다. 원문 표는 C:0000~E:1fff RAM과 대응 ROM range를 모든 bit 조합별로 보존합니다.

LCS-8830(-T) (8 and 16-bit cards)
---------------------------------
- from Mathias Katzer <[email protected]>
- Marek Michalkiewicz <[email protected]> says the
LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
only (the JP0 jumper is hardwired), and BNC only.
This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
nowhere else, not even on the few Xeroxed sheets from the manual).

PureData PDI507
1145-1298PureData Corp PDI507 8-bit card
Mark Rejhon의 자료를 Avery가 조금 수정했습니다. PDI508은 대체로 비슷할 수 있지만 PDI508Plus는 software 구성 방식이라 다릅니다.
Card 아래 edge connector 근처 J1 array는 IRQ와 다른 기능을 제어하며 IRQ pin에는 jumper 하나만 둡니다. ETS1·ETS2는 매우 긴 network timing용입니다. J2에는 원래 있던 jumper를 유지하는 편이 좋지만 기능은 알려지지 않았습니다.
J3는 2x3 pin에 jumper 두 개를 쓰며 Carl de Billy의 설명에 따르면 coax bus에서는 J4를 제거합니다. Twisted-pair bus에서는 J3가 middle pin과 RJ11 쪽 pin을 연결하도록 옮기고 J4를 제거합니다. Twisted-pair STAR도 J3를 같은 방향으로 옮깁니다.
설치 후 접근 가능한 8-bit DIP는 ARCnet address를 정하며 1~254를 사용합니다. Bit 의미가 반대라 00000000은 FF, 11111111은 0이며 둘 다 사용하면 안 됩니다.
Card 위쪽의 다른 8-bit DIP에는 memory를 정하는 MS0~MS4와 I/O base를 정하는 IO0~IO2가 있습니다. 시험은 switch 변경 후 reboot하고 여러 address로 ARCETHER를 load해 red TX LED가 blink하는지 보는 방식이었습니다. 0x3D0은 driver가 load되지만 LED가 blink하지 않는 특수 동작이 관찰됐습니다. Windows 호환성을 위해 0x300을 권장합니다.
IO bit 210은 111=0x260, 110=0x290, 101=0x2E0, 100=0x2F0, 011=0x300, 010=0x350, 001=0x380, 000=0x3E0입니다.
Memory switch는 4 KiB address 영역을 reserve합니다. QEMM386 stealth와 LOADHI를 사용해 제외 영역을 확인했습니다. 0xD000을 ARCnet memory, 0xC000을 EMS page frame으로 권장합니다. MS0 OFF가 제대로 동작하지 않았을 수 있으므로 먼저 ON으로 시험합니다. 원문 표의 일부 C400~E100 값은 추정이며 C400~C900 일부는 시험 system을 crash시켰다고 표시되어 있습니다.

PDI507 (8-bit card)
--------------------
- from Mark Rejhon <[email protected]> (slight modifications by Avery)
- Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
are mostly the same as this. PDI508Plus cards appear to be mainly
software-configured.
Jumpers:
There is a jumper array at the bottom of the card, near the edge
connector. This array is labelled J1. They control the IRQs and
something else. Put only one jumper on the IRQ pins.
ETS1, ETS2 are for timing on very long distance networks. See the
more general information near the top of this file.
There is a J2 jumper on two pins. A jumper should be put on them,
since it was already there when I got the card. I don't know what
this jumper is for though.
There is a two-jumper array for J3. I don't know what it is for,
but there were already two jumpers on it when I got the card. It's
a six pin grid in a two-by-three fashion. The jumpers were
configured as follows::
.-------.
o | o o |
:-------: ------> Accessible end of card with connectors
o | o o | in this direction ------->
`-------'
Carl de Billy <[email protected]> explains J3 and J4:

- If using coax cable in a bus topology the J4 jumper must be removed;
place it on one pin.
- If using bus topology with twisted pair wiring move the J3
jumpers so they connect the middle pin and the pins closest to the RJ11
Connectors. Also the J4 jumper must be removed; place it on one pin of
J4 jumper for storage.
- If using star topology with twisted pair wiring move the J3
jumpers so they connect the middle pin and the pins closest to the RJ11
connectors.
DIP Switches:
The DIP switches accessible on the accessible end of the card while
it is installed, is used to set the ARCnet address. There are 8
switches. Use an address from 1 to 254
========== =========================
Switch No. ARCnet address
12345678
========== =========================
00000000 FF (Don't use this!)

...
11111101 2
11111110 1
11111111 0 (Don't use this!)
========== =========================
There is another array of eight DIP switches at the top of the
card. There are five labelled MS0-MS4 which seem to control the
memory address, and another three labelled IO0-IO2 which seem to
control the base I/O address of the card.
This was difficult to test by trial and error, and the I/O addresses
are in a weird order. This was tested by setting the DIP switches,
rebooting the computer, and attempting to load ARCETHER at various
addresses (mostly between 0x200 and 0x400). The address that caused
the red transmit LED to blink, is the one that I thought works.
Also, the address 0x3D0 seem to have a special meaning, since the
ARCETHER packet driver loaded fine, but without the red LED
blinking. I don't know what 0x3D0 is for though. I recommend using
an address of 0x300 since Windows may not like addresses below
0x300.
============= ===========
IO Switch No. I/O address

100 0x2F0
011 0x300
010 0x350
001 0x380
000 0x3E0
============= ===========
The memory switches set a reserved address space of 0x1000 bytes
(0x100 segment units, or 4k). For example if I set an address of
0xD000, it will use up addresses 0xD000 to 0xD100.
The memory switches were tested by booting using QEMM386 stealth,
and using LOADHI to see what address automatically became excluded
from the upper memory regions, and then attempting to load ARCETHER
using these addresses.
I recommend using an ARCnet memory address of 0xD000, and putting
the EMS page frame at 0xC000 while using QEMM stealth mode. That
way, you get contiguous high memory from 0xD100 almost all the way
the end of the megabyte.
Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
on my card. It could be malfunctioning on my card. Experiment with
it ON first, and if it doesn't work, set it to OFF. (It may be a
modifier for the 0x200 bit?)

Juergen Seifert가 CNet manual P/N 12-01-0007 Revision 3.00을 바탕으로 작성했습니다. 120A는 STAR, 120AB는 BUS, 120TP는 twisted pair, 120ST는 STAR+twisted pair, 120SBT는 STAR+BUS+twisted pair입니다.
90C65 ARCnet chip을 사용합니다. SW1 1~5는 memory, 6~8은 I/O, SW2 1~8은 node ID입니다. JP1은 ROM, JP2~JP6은 IRQ2·3·4·5·7, JP7·JP8은 ET1·ET2, JP10·JP11은 coax·twisted pair, JP12는 terminator입니다. J1은 BNC, J2는 model에 따라 telephone jack입니다. OFF는 1, ON은 0입니다.
SW2 switch 1(ID0)이 LSB이며 OFF인 switch의 1·2·4·8·16·32·64·128 값을 합산합니다. Node ID는 unique하고 0이 아니어야 합니다.
SW1 6~8은 I/O base 260, 290, 2E0(기본), 2F0, 300, 350, 380, 3E0을 선택합니다.
2 KiB RAM buffer base는 SW1 1~5가 정하며 boot PROM은 memory base+8 KiB입니다. 지원 RAM base는 C0000, C4000, CC000, D0000(기본), D4000, D8000, DC000, E0000이고 JP1로 boot ROM을 켭니다. 항상 ON인 switch 1·2가 2·4·6 KiB offset을 더할 가능성이 있지만 manual에 없고 시험하지 않았습니다.
IRQ는 JP2~JP6 중 정확히 하나를 설치하며 JP2=IRQ2가 기본입니다.
JP12는 internal terminator를 켜고 끕니다. JP10·JP11은 CN120ST·SBT에서 coax(기본) 또는 twisted pair connector를 선택합니다. EXT1·EXT2 timeout jumper는 보통 open입니다.

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in SW2 are used to set the node ID. Each node attached
to the network must have an unique node ID which must be different from 0.
Switch 1 (ID0) serves as the least significant bit (LSB).
The node ID is the sum of the values of all switches set to "1"
These values are:

Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The last three switches in switch block SW1 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
6 7 8 | Address
------------|--------
ON ON ON | 260
OFF ON ON | 290
ON OFF ON | 2E0 (Manufacturer's default)
OFF OFF ON | 2F0
ON ON OFF | 300
OFF ON OFF | 350
ON OFF OFF | 380
OFF OFF OFF | 3E0
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer (RAM) requires 2K. The base of this buffer can be
located in any of eight positions. The address of the Boot Prom is
memory base + 8K or memory base + 0x2000.
Switches 1-5 of switch block SW1 select the Memory Base address.

Since the switches 1 and 2 are always set to ON it may be possible
that they can be used to add an offset of 2K, 4K or 6K to the base
address, but this feature is not documented in the manual and I
haven't tested it yet.
Setting the Interrupt Line
^^^^^^^^^^^^^^^^^^^^^^^^^^
To select a hardware interrupt level install one (only one!) of the jumpers
JP2, JP3, JP4, JP5, JP6. JP2 is the default::
Jumper | IRQ
-------|-----
2 | 2
3 | 3
4 | 4
5 | 5
6 | 7
Setting the Internal Terminator on CN120AB/TP/SBT
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The jumper JP12 is used to enable the internal terminator::
-----
0 | 0 |
----- ON | | ON
| 0 | | 0 |
| | OFF ----- OFF
| 0 | 0
-----
Terminator Terminator

Juergen Seifert가 CNet manual P/N 12-01-0006 Revision 3.00을 바탕으로 작성했습니다. CN160A는 STAR, CN160AB는 BUS, CN160TP는 twisted pair model입니다.
SW1 1~6은 I/O base, 7~10은 memory base, SW2 1~8은 node ID입니다. JP1·JP2는 ET1·ET2, JP3~JP13은 interrupt, J1은 model별 BNC 또는 telephone jack입니다. OFF는 1, ON은 0입니다.
Node ID는 SW2 switch 1(ID0)이 LSB이며 OFF bit 값을 합산합니다. 0은 허용하지 않습니다.
문서화된 I/O base 조합은 260, 290, 2E0(기본), 2F0, 300, 350, 380, 3E0입니다. 다른 조합도 선택 가능해 보이지만 manual에는 없습니다.
SW1 7~10의 문서화된 RAM·ROM base는 C0000·C8000, D0000·D8000(기본), E0000·E8000입니다. 다른 memory base도 가능해 보이나 문서화되지 않았습니다.
Interrupt는 JP3~JP13 중 정확히 하나로 IRQ14, 15, 12, 11, 10, 3, 4, 5, 6, 7, 2(=9, 기본)를 고릅니다. JP11=IRQ6은 floppy controller와 충돌할 수 있어 쓰지 말아야 하며, JP3=IRQ14는 IDE·MFM·RLL disk가 없을 때만 사용합니다.
JP1·JP2 timeout jumper는 보통 open입니다.

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in SW2 are used to set the node ID. Each node attached
to the network must have an unique node ID which must be different from 0.
Switch 1 (ID0) serves as the least significant bit (LSB).
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Label | Value
-------|-------|-------
1 | ID0 | 1
2 | ID1 | 2
3 | ID2 | 4
4 | ID3 | 8
5 | ID4 | 16
6 | ID5 | 32
7 | ID6 | 64
8 | ID7 | 128
Some Examples::
Switch | Hex | Decimal
8 7 6 5 4 3 2 1 | Node ID | Node ID
----------------|---------|---------
0 0 0 0 0 0 0 0 | not allowed
0 0 0 0 0 0 0 1 | 1 | 1
0 0 0 0 0 0 1 0 | 2 | 2
0 0 0 0 0 0 1 1 | 3 | 3
. . . | |
0 1 0 1 0 1 0 1 | 55 | 85
. . . | |
1 0 1 0 1 0 1 0 | AA | 170
. . . | |
1 1 1 1 1 1 0 1 | FD | 253
1 1 1 1 1 1 1 0 | FE | 254
1 1 1 1 1 1 1 1 | FF | 255
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The first six switches in switch block SW1 are used to select the I/O Base
address using the following table::
Switch | Hex I/O
1 2 3 4 5 6 | Address
------------------------|--------
OFF ON ON OFF OFF ON | 260
OFF ON OFF ON ON OFF | 290
OFF ON OFF OFF OFF ON | 2E0 (Manufacturer's default)
OFF ON OFF OFF OFF OFF | 2F0
OFF OFF ON ON ON ON | 300
OFF OFF ON OFF ON OFF | 350
OFF OFF OFF ON ON ON | 380
OFF OFF OFF OFF OFF ON | 3E0
Note: Other IO-Base addresses seem to be selectable, but only the above
combinations are documented.
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The switches 7-10 of switch block SW1 are used to select the Memory
Base address of the RAM (2K) and the PROM::
Switch | Hex RAM | Hex ROM
7 8 9 10 | Address | Address
----------------|---------|-----------
OFF OFF ON ON | C0000 | C8000
OFF OFF ON OFF | D0000 | D8000 (Default)
OFF OFF OFF ON | E0000 | E8000
.. note::
Other MEM-Base addresses seem to be selectable, but only the above
combinations are documented.
Setting the Interrupt Line
^^^^^^^^^^^^^^^^^^^^^^^^^^
To select a hardware interrupt level install one (only one!) of the jumpers
JP3 through JP13 using the following table::
Jumper | IRQ
-------|-----------------
3 | 14
4 | 15
5 | 12
6 | 11
7 | 10
8 | 3
9 | 4
10 | 5
11 | 6
12 | 7
13 | 2 (=9) Default!
.. note::
- Do not use JP11=IRQ6, it may conflict with your Floppy Disk
Controller
- Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
Hard Disk, it may conflict with their controllers
Setting the Timeout Parameters
------------------------------
The jumpers labeled JP1 and JP2 are used to determine the timeout
parameters. These two jumpers are normally left open.
Lantech 무명 8-bit card
1701-1782Lantech 8-bit card, model 미상
Vlad Lungu가 제공한 UM9065L ARCnet controller card 정보입니다.
SW1은 shared-memory와 I/O base를 정하며 ON=0입니다. Memory bit 12345의 확인값에는 D4000, CC000, D0000, D1000, D9000, CC800, DC800, D1800이 있습니다. Bit 순서가 뒤집힌 것으로 보이고 일부 address는 probe하지 않고 DOS memory dump로 확인했습니다. 00000 등 일부 설정은 S3 GENDAC video card와 충돌했습니다.
SW1 678의 I/O 값은 000=260, 010=2E0, 011=380, 100=290, 101=350, 111=3E0이며 001과 110은 probe에 실패했습니다.
SW2는 binary-coded node ID, JP4는 closed일 때 boot PROM enable, open일 때 disable입니다. JP6은 IRQ2~IRQ6 중 하나만 선택합니다.

It seems that the bits are considered in reverse order. Also, you must
observe that some of those addresses are unusual and I didn't probe them; I
used a memory dump in DOS to identify them. For the 00000 configuration and
some others that I didn't write here the card seems to conflict with the
video card (an S3 GENDAC). I leave the full decoding of those addresses to
you.

Acer 5210-003
1783-1952Acer 8-bit card model 5210-003
Vojtech Pavlik이 기존 자료 일부를 이용해 작성했습니다. 90C26 기반이며 SMC PC100과 비슷하지만 의미를 모르는 jumper가 더 있습니다.
SW1 1~6은 I/O, 7~10은 memory, SW2 1~8은 node ID입니다. J1~J5는 IRQ이고 J6~J21은 아마 timeout·ROM 관련 추가 jumper지만 미확인입니다. LED1은 activity, BNC는 STAR coax, RAM은 2 KiB SRAM, ROM은 boot socket, UFS는 기능 미상의 socket입니다.
SW2 switch 1(ID0)이 LSB이고 OFF=1, ON=0입니다. OFF bit 값을 합산해 node ID를 만들며 0과 255는 reserved입니다.
SW1 1~6의 OFF bit 값 0x200, 0x100, 0x80, 0x40, 0x20, 0x10을 합산해 I/O address를 만듭니다. 0x200 아래는 mainboard reserved 영역이므로 switch 1은 항상 OFF로 두어 0x200 bit를 포함해야 합니다.
2 KiB RAM은 16개 위치를 선택할 수 있지만 A0000 아래는 main RAM과 겹쳐 system hang 가능성이 큽니다. 문서화된 SW1 7~10 조합에는 F0000(BIOS 충돌), E0000, D0000, C0000(video BIOS 충돌), B0000(monochrome video 충돌), A0000(graphics 충돌)이 있습니다.
J1 1~5 중 하나를 short해 IRQ7, 5, 4, 3, 2를 선택합니다.
J16·J17은 timeout, J18~J21 중 하나는 ROM 선택일 가능성이 있지만 확인되지 않았습니다. J6~J10과 J11~J15는 IRQ2~7을 UFS pin에 연결하나 목적은 알 수 없습니다.

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in SW2 are used to set the node ID. Each node attached
to the network must have an unique node ID which must not be 0.
Switch 1 (ID0) serves as the least significant bit (LSB).
Setting one of the switches to OFF means "1", ON means "0".
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Value
-------|-------
1 | 1
2 | 2
3 | 4
4 | 8
5 | 16
6 | 32
7 | 64
8 | 128
Don't set this to 0 or 255; these values are reserved.
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The switches 1 to 6 of switch block SW1 are used to select one
of 32 possible I/O Base addresses using the following tables::
| Hex
Switch | Value
-------|-------
1 | 200
2 | 100
3 | 80
4 | 40
5 | 20
6 | 10
The I/O address is sum of all switches set to "1". Remember that
the I/O address space below 0x200 is RESERVED for mainboard, so
switch 1 should be ALWAYS SET TO OFF.
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer (RAM) requires 2K. The base of this buffer can be
located in any of sixteen positions. However, the addresses below
A0000 are likely to cause system hang because there's main RAM.
Jumpers 7-10 of switch block SW1 select the Memory Base address::
Switch | Hex RAM
7 8 9 10 | Address
----------------|---------
OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
OFF OFF OFF ON | E0000
OFF OFF ON OFF | D0000
OFF OFF ON ON | C0000 (conflicts with video BIOS)
OFF ON OFF OFF | B0000 (conflicts with mono video)
OFF ON OFF ON | A0000 (conflicts with graphics)
Setting the Interrupt Line
^^^^^^^^^^^^^^^^^^^^^^^^^^
Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
shorted, OFF means open::
Jumper | IRQ
1 2 3 4 5 |
----------------------------
ON OFF OFF OFF OFF | 7
OFF ON OFF OFF OFF | 5
OFF OFF ON OFF OFF | 4
OFF OFF OFF ON OFF | 3
OFF OFF OFF OFF ON | 2
Unknown jumpers & sockets
^^^^^^^^^^^^^^^^^^^^^^^^^
I know nothing about these. I just guess that J16&J17 are timeout
jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
guess the purpose.
LAN-ARC-8
1953-2098제조사가 Datapoint일 가능성이 있는 LAN-ARC-8 8-bit card
Vojtech Pavlik이 제공했습니다. SMC 90C65 기반이며 제조사는 확인하지 못했지만 우측 상단의 원래 arcNet logo 때문에 DataPoint일 수 있습니다.
SW1 1~5는 memory, 6~8은 I/O, SW2 1~8은 node ID, SW3 1~5는 IRQ, 6~7은 timeout, 8은 ROM enable입니다. BNC, 20 MHz crystal, 2 KiB RAM, EPROM socket이 있습니다.
원문 node-ID 절은 SW3라고 적지만 board legend는 SW2를 node ID로 지정합니다. Switch 1이 LSB이고 OFF=1, ON=0이며 OFF bit 값을 합산합니다.
SW1 6~8 I/O base는 260, 290, 2E0(기본), 2F0, 300, 350, 380, 3E0입니다.
2 KiB RAM base는 C0000, C4000, CC000, D0000(기본), D4000, D8000, DC000, E0000이며 boot PROM은 base+0x2000입니다. SW3 switch 8을 ON으로 해 boot ROM을 켭니다. SW1 1·2는 RAM base에 0x0800·0x1000을 더할 가능성이 있습니다.
SW3 1~5는 IRQ3, 4, 5, 7, 2 중 하나를 선택합니다. SW3 6~7 timeout switch는 보통 OFF입니다.
Datapoint?

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in SW3 are used to set the node ID. Each node attached
to the network must have an unique node ID which must not be 0.
Switch 1 serves as the least significant bit (LSB).
Setting one of the switches to Off means "1", On means "0".
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Value
-------|-------
1 | 1
2 | 2
3 | 4
4 | 8
5 | 16
6 | 32
7 | 64
8 | 128
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The last three switches in switch block SW1 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
6 7 8 | Address
------------|--------
ON ON ON | 260
OFF ON ON | 290
ON OFF ON | 2E0 (Manufacturer's default)
OFF OFF ON | 2F0
ON ON OFF | 300
OFF ON OFF | 350
ON OFF OFF | 380
OFF OFF OFF | 3E0
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer (RAM) requires 2K. The base of this buffer can be
located in any of eight positions. The address of the Boot Prom is
memory base + 0x2000.
Jumpers 3-5 of switch block SW1 select the Memory Base address.
::
Switch | Hex RAM | Hex ROM
1 2 3 4 5 | Address | Address *)
--------------------|---------|-----------
ON ON ON ON ON | C0000 | C2000
ON ON OFF ON ON | C4000 | C6000
ON ON ON OFF ON | CC000 | CE000
ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
ON ON ON ON OFF | D4000 | D6000
ON ON OFF ON OFF | D8000 | DA000
ON ON ON OFF OFF | DC000 | DE000
ON ON OFF OFF OFF | E0000 | E2000
*) To enable the Boot ROM set the switch 8 of switch block SW3 to position ON.
The switches 1 and 2 probably add 0x0800 and 0x1000 to RAM base address.
Setting the Interrupt Line
^^^^^^^^^^^^^^^^^^^^^^^^^^
Switches 1-5 of the switch block SW3 control the IRQ level::
Jumper | IRQ
1 2 3 4 5 |
----------------------------
ON OFF OFF OFF OFF | 3
OFF ON OFF OFF OFF | 4
OFF OFF ON OFF OFF | 5
OFF OFF OFF ON OFF | 7
OFF OFF OFF OFF ON | 2
Setting the Timeout Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The switches 6-7 of the switch block SW3 are used to determine the timeout
parameters. These two switches are normally left in the OFF position.

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in SW2 are used to set the node ID. Each node attached to
the network must have an unique node ID which must not be 0. Switch 1 (ID0)
serves as the least significant bit (LSB).
Setting one of the switches to Off means "1", On means "0".
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Label | Value
-------|-------|-------
1 | ID0 | 1
2 | ID1 | 2
3 | ID2 | 4
4 | ID3 | 8
5 | ID4 | 16
6 | ID5 | 32
7 | ID6 | 64
8 | ID7 | 128
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The last three switches in switch block SW1 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
6 7 8 | Address
------------|--------
ON ON ON | 260 (Manufacturer's default)
OFF ON ON | 290
ON OFF ON | 2E0
OFF OFF ON | 2F0
ON ON OFF | 300
OFF ON OFF | 350
ON OFF OFF | 380
OFF OFF OFF | 3E0
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer (RAM) requires 2K. The base of this buffer can be
located in any of eight positions. The address of the Boot Prom is
memory base + 0x2000.
Jumpers 3-5 of switch block SW1 select the Memory Base address.
::
Switch | Hex RAM | Hex ROM
1 2 3 4 5 | Address | Address *)
--------------------|---------|-----------
ON ON ON ON ON | C0000 | C2000
ON ON OFF ON ON | C4000 | C6000 (Manufacturer's default)
ON ON ON OFF ON | CC000 | CE000
ON ON OFF OFF ON | D0000 | D2000
ON ON ON ON OFF | D4000 | D6000
ON ON OFF ON OFF | D8000 | DA000
ON ON ON OFF OFF | DC000 | DE000
ON ON OFF OFF OFF | E0000 | E2000
*) To enable the Boot ROM short the jumper J2.
The jumpers 1 and 2 probably add 0x0800 and 0x1000 to RAM address.
Setting the Interrupt Line
^^^^^^^^^^^^^^^^^^^^^^^^^^
Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
shorted, OFF means open::
Jumper | IRQ
1 2 3 4 5 |
----------------------------
ON OFF OFF OFF OFF | 2
OFF ON OFF OFF OFF | 3
OFF OFF ON OFF OFF | 4
OFF OFF OFF ON OFF | 5
OFF OFF OFF OFF ON | 7
Setting the Timeout Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The jumpers J3 are used to set the timeout parameters. These two
jumpers are normally left open.

2245-2338Thomas-Conrad model 500-6242-0097 REV A 8-bit card
Lars Karlsson의 자료입니다.
Board에는 I/O용 SW3, base address용 SW1, station-address switch, boot PROM socket, IRQ jumper, BNC, 110 Ohm terminator가 있는 RJ connector, 사용하지 않는 RJ jack, red diagnostic LED가 있습니다.
I/O switch 1~8 예로 2E0=00010001, 2F0=00010000, 300=00001111, 350=00001110입니다. 이 표에서 0은 OFF, 1은 ON입니다.
Shared-memory switch는 C/D segment와 X000·X400·X800·XC00 offset을 조합합니다. Switch 8은 `ENHANCED`=1 또는 `COMPATIBLE`=0을 선택합니다. IRQ jumper는 3, 4, 5, 7, 2용 pin입니다.
실물 두 장 중 enhanced로 설정된 card는 driver가 인식하지 못했고 compatible card는 정상 동작했습니다. Enhanced의 목적은 확인되지 않았습니다. Avery는 shared memory 또는 I/O port 중 하나를 끄는 mode일 수 있다고 추정하며 자세한 정보가 없다면 compatible mode를 사용하라고 권합니다.

There is a DIP-switch with 8 switches, used to set the shared memory address
to be used. The first 6 switches set the address, the 7th doesn't have any
function, and the 8th switch is used to select "compatible" or "enhanced".
When I got my two cards, one of them had this switch set to "enhanced". That
card didn't work at all, it wasn't even recognized by the driver. The other
card had this switch set to "compatible" and it behaved absolutely normally. I
guess that the switch on one of the cards, must have been changed accidentally
when the card was taken out of its former host. The question remains
unanswered, what is the purpose of the "enhanced" position?
[Avery's note: "enhanced" probably either disables shared memory (use IO
ports instead) or disables IO ports (use memory addresses instead). This
varies by the type of card involved. I fail to see how either of these
enhance anything. Send me more detailed information about this mode, or
just use "compatible" mode instead.]
Waterloo Microsystems 1985 card
2339-2445Waterloo Microsystems일 가능성이 있는 1985년 8-bit card
Robert Michael Best의 자료입니다.
당시 driver에서는 동작하지 않았습니다. PDI508Plus처럼 software-configured card와 설정이 비슷해 보입니다. `Waterloo` chip은 University of Waterloo 전용 boot PROM일 가능성이 있습니다. J2의 어떤 설정에서도 probe하지 못했고 Waterloo chip을 제거한 뒤에도 같았습니다.
Board에는 COM9026, Waterloo EPROM, COM9032, 여러 74LS, 20 MHz M-TRON oscillator, MOSTEK MK6116N-20, 미표기 C7, PAL10L8CN, PAL16R4A-2CN, M8640 NMC 9306N과 resin-coated daughterboard가 있습니다.
J2는 1~6 번호의 jumper bank이며 4·5는 solder point 때문에 stamp가 없습니다. J3는 IRQ2~7입니다. Board에는 maple leaf, `ASS 'Y 300163`, `@1986 CORMAN CUSTOM ELECTRONICS CORP.`, `MADE IN CANADA` 표기가 있습니다.

-------------------
- from Robert Michael Best <[email protected]>
[Avery's note: these don't work with my driver for some reason. These cards
SEEM to have settings similar to the PDI508Plus, which is
software-configured and doesn't work with my driver either. The "Waterloo
chip" is a boot PROM, probably designed specifically for the University of
Waterloo. If you have any further information about this card, please
e-mail me.]
The probe has not been able to detect the card on any of the J2 settings,
and I tried them again with the "Waterloo" chip removed.

Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in group SW1 are used to set the node ID.
Each node attached to the network must have an unique node ID which
must be different from 0.
Switch 8 serves as the least significant bit (LSB).
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Value
-------|-------
8 | 1
7 | 2
6 | 4
5 | 8
4 | 16

Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The first three switches in switch group SW2 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
1 2 3 | Address
------------|--------
ON ON ON | 260
ON ON OFF | 290
ON OFF ON | 2E0 (Manufacturer's default)
ON OFF OFF | 2F0
OFF ON ON | 300
OFF ON OFF | 350
OFF OFF ON | 380
OFF OFF OFF | 3E0
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer requires 2K of a 16K block of RAM. The base of this
16K block can be located in any of eight positions.
Switches 4-6 of switch group SW2 select the Base of the 16K block.
Within that 16K address space, the buffer may be assigned any one of four
positions, determined by the offset, switches 7 and 8 of group SW2.

*) To enable the 8K Boot PROM install the jumper ROM.
The default is jumper ROM not installed.
Setting Interrupt Request Lines (IRQ)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To select a hardware interrupt level set one (only one!) of the jumpers
IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
Setting the Timeouts
^^^^^^^^^^^^^^^^^^^^
The two jumpers labeled ET1 and ET2 are used to determine the timeout
parameters (response and reconfiguration time). Every node in a network
must be set to the same timeout values.
::
ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
--------|--------------------|--------------------------
Off Off | 78 | 840 (Default)
Off On | 285 | 1680
On Off | 563 | 1680
On On | 1130 | 1680
On means jumper installed, Off means jumper not installed

같은 8-bit NONAME manual에는 16-bit coax·twisted-pair card 설명도 있지만 booklet에서 두 page가 빠져 있어 불완전합니다. Board 그림에도 `SW1` 같은 label이 없어 품질이 낮습니다. Juergen Seifert가 원 manual을 바탕으로 작성했고 보유자는 정보를 보완해 달라고 요청합니다.
Switch OFF는 1, ON은 0입니다.
SW2 8-bit가 node ID를 정하고 switch 8이 LSB입니다. 0은 허용하지 않으며 OFF bit 값을 합산합니다.
SW1 1~3은 I/O base 260, 290, 2E0(기본), 2F0, 300, 350, 380, 3E0을 선택합니다.
SW1 6~8은 16 KiB memory block base, 4~5는 2 KiB buffer offset을 고릅니다. 원문 표는 C0000~E1800 RAM과 대응 ROM address를 모두 보존합니다.
IRQ와 timeout 절은 원문 자체가 물음표만으로 남아 있어 설정 정보가 없습니다.
16-BIT ARCNET
-------------
The manual of my 8-Bit NONAME ARCnet Card contains another description
of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
because there are missing two pages in the manual booklet. (The table
of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
the booklet there is a different way of counting ... 2-9, 2-10, A-1,
(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
Also the picture of the board layout is not as good as the picture of
8-Bit card, because there isn't any letter like "SW1" written to the
picture.
Should somebody have such a board, please feel free to complete this
description or to send a mail to me!

Made in Taiwan R.O.C. 8-bit card
2828-2993`MADE IN TAIWAN R.O.C.` 8-bit card
Vojtech Pavlik이 manual 없이 card만 보고 작성했습니다. Manufacturer 식별 문구가 해당 표기뿐이라 NONAME이라 불렀습니다.
90C65를 사용하며 SW1 1~5는 memory, 6~8은 I/O, SW2는 node ID, SW3 1~5는 IRQ, 6~7은 timeout, 8은 ROM, JP1은 LED connector입니다. BNC coax connector가 있습니다.
SW1과 SW3은 `SW`라고 표시됐지만 switch가 아니라 jumper입니다. ON은 위쪽 두 pin 연결, OFF는 아래쪽 두 pin 연결이며 IRQ에서는 아무 pin도 연결하지 않는 상태입니다.
SW2 switch 1(ID0)이 LSB이고 OFF=1, ON=0입니다. 0은 허용하지 않습니다.
SW1 6~8 I/O base는 260, 290, 2E0(기본), 2F0, 300, 350, 380, 3E0입니다.
2 KiB RAM base는 C0000, C4000, CC000, D0000(기본), D4000, D8000, DC000, E0000이며 boot PROM은 base+0x2000입니다. SW3 jumper 8을 ON으로 해 ROM을 켭니다. SW1 1·2는 0x0800, 0x1000, 0x1800 offset을 더할 가능성이 있습니다.
SW3 1~5는 IRQ2, 3, 4, 5, 7을 선택하고 6~7 timeout jumper는 보통 OFF입니다.

- from Vojtech Pavlik <[email protected]>
I have named this ARCnet card "NONAME", since I got only the card with
no manual at all and the only text identifying the manufacturer is
"MADE IN TAIWAN R.O.C" printed on the card.

SW2 1-8: Node ID Select (ID0-ID7)
SW3 1-5: IRQ Select
6-7: Extra Timeout
8 : ROM Enable
JP1 Led connector

Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
switches.
Setting the jumpers to ON means connecting the upper two pins, off the bottom
two - or - in case of IRQ setting, connecting none of them at all.
Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in SW2 are used to set the node ID. Each node attached
to the network must have an unique node ID which must not be 0.
Switch 1 (ID0) serves as the least significant bit (LSB).
Setting one of the switches to Off means "1", On means "0".
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Label | Value
-------|-------|-------
1 | ID0 | 1
2 | ID1 | 2
3 | ID2 | 4
4 | ID3 | 8
5 | ID4 | 16
6 | ID5 | 32
7 | ID6 | 64
8 | ID7 | 128
Some Examples::
Switch | Hex | Decimal

----------------|---------|---------
0 0 0 0 0 0 0 0 | not allowed

1 1 1 1 1 1 1 0 | FE | 254
1 1 1 1 1 1 1 1 | FF | 255
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The last three switches in switch block SW1 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
6 7 8 | Address
------------|--------
ON ON ON | 260
OFF ON ON | 290
ON OFF ON | 2E0 (Manufacturer's default)
OFF OFF ON | 2F0
ON ON OFF | 300
OFF ON OFF | 350
ON OFF OFF | 380
OFF OFF OFF | 3E0
Setting the Base Memory (RAM) buffer Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer (RAM) requires 2K. The base of this buffer can be
located in any of eight positions. The address of the Boot Prom is
memory base + 0x2000.
Jumpers 3-5 of jumper block SW1 select the Memory Base address.
::
Switch | Hex RAM | Hex ROM
1 2 3 4 5 | Address | Address *)
--------------------|---------|-----------
ON ON ON ON ON | C0000 | C2000
ON ON OFF ON ON | C4000 | C6000
ON ON ON OFF ON | CC000 | CE000
ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
ON ON ON ON OFF | D4000 | D6000
ON ON OFF ON OFF | D8000 | DA000
ON ON ON OFF OFF | DC000 | DE000
ON ON OFF OFF OFF | E0000 | E2000
*) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
Setting the Interrupt Line
^^^^^^^^^^^^^^^^^^^^^^^^^^
Jumpers 1-5 of the jumper block SW3 control the IRQ level::
Jumper | IRQ
1 2 3 4 5 |
----------------------------
ON OFF OFF OFF OFF | 2
OFF ON OFF OFF OFF | 3
OFF OFF ON OFF OFF | 4
OFF OFF OFF ON OFF | 5
OFF OFF OFF OFF ON | 7
Setting the Timeout Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
parameters. These two jumpers are normally left in the OFF position.

Andrew J. Kroll의 자료입니다.
SL90C65 controller를 사용합니다. SW1 1~5는 IRQ3·4·5·7·2, 6은 ET1, 7은 ET2, 8은 ROM enable입니다. SW2 1~3은 memory buffer·PROM address, 4~6은 I/O map, SW3 1~8은 node ID입니다. BNC RG62/U connector가 있으며 제공자는 RG59B/U를 terminator 없이 사용해도 동작했다고 기록했습니다.
IRQ는 SW1 1~5 중 정확히 하나만 ON으로 두며 제조사 기본은 IRQ2입니다. EXT1·EXT2는 보통 OFF이고 SW1 8을 UP으로 하면 8 KiB boot PROM을 켭니다.
SW2 4~6 I/O base는 260, 290, 2E0(기본), 2F0, 300, 350, 380, 3E0입니다.
SW2 1~3은 memory block base를 정하지만 E0000·E2000과 D0000·D2000(기본) 두 설정만 검증됐고 나머지는 원문에서 `?????`로 남아 있습니다.
SW3 switch 1이 LSB이고 DOWN=OFF(0), UP=ON(1)입니다. ON bit 값을 합산하며 0과 255를 사용하면 안 됩니다.

What gives?!
SW1: Timeouts, Interrupt and ROM
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To select a hardware interrupt level set one (only one!) of the dip switches
up (on) SW1...(switches 1-5)
IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
are used to determine the timeout parameters. These two dip switches
are normally left off (down).
To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
The default is jumper ROM not installed.
Setting the I/O Base Address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The last three switches in switch group SW2 are used to select one
of eight possible I/O Base addresses using the following table::
Switch | Hex I/O
4 5 6 | Address
-------|--------
0 0 0 | 260
0 0 1 | 290

1 0 0 | 300
1 0 1 | 350
1 1 0 | 380
1 1 1 | 3E0
Setting the Base Memory Address (RAM & ROM)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The memory buffer requires 2K of a 16K block of RAM. The base of this
16K block can be located in any of eight positions.
Switches 1-3 of switch group SW2 select the Base of the 16K block.
(0 = DOWN, 1 = UP)
I could, however, only verify two settings...

1 0 1 | ????? | ?????
1 1 0 | ????? | ?????
1 1 1 | ????? | ?????
Setting the Node ID
^^^^^^^^^^^^^^^^^^^
The eight switches in group SW3 are used to set the node ID.
Each node attached to the network must have an unique node ID which
must be different from 0.
Switch 1 serves as the least significant bit (LSB).
switches in the DOWN position are OFF (0) and in the UP position are ON (1)
The node ID is the sum of the values of all switches set to "1"
These values are::
Switch | Value

1 | 1
2 | 2
3 | 4
