11without manuals, this file contains a quick introduction to ARCnet hardware,
12some cabling tips, and a listing of all jumper settings I can find. Please

17INTRODUCTION TO ARCNET
18----------------------
19
20ARCnet is a network type which works in a way similar to popular Ethernet
21networks but which is also different in some very important ways.
22
23First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
24(slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
25there are others as well, but these are less common. The different hardware
26types, as far as I'm aware, are not compatible and so you cannot wire a
27100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
28work with 100 Mbps cards, but I haven't been able to verify this myself,
29since I only have the 2.5 Mbps variety. It is probably not going to saturate
30your 100 Mbps card. Stop complaining. :)
31
32You also cannot connect an ARCnet card to any kind of Ethernet card and
33expect it to work.
34
35There are two "types" of ARCnet - STAR topology and BUS topology. This
36refers to how the cards are meant to be wired together. According to most
37available documentation, you can only connect STAR cards to STAR cards and
38BUS cards to BUS cards. That makes sense, right? Well, it's not quite
39true; see below under "Cabling."
40
41Once you get past these little stumbling blocks, ARCnet is actually quite a
42well-designed standard. It uses something called "modified token passing"
43which makes it completely incompatible with so-called "Token Ring" cards,
44but which makes transfers much more reliable than Ethernet does. In fact,
45ARCnet will guarantee that a packet arrives safely at the destination, and
46even if it can't possibly be delivered properly (ie. because of a cable
47break, or because the destination computer does not exist) it will at least
48tell the sender about it.
49
50Because of the carefully defined action of the "token", it will always make
51a pass around the "ring" within a maximum length of time. This makes it
52useful for realtime networks.
53
54In addition, all known ARCnet cards have an (almost) identical programming
55interface. This means that with one ARCnet driver you can support any
56card, whereas with Ethernet each manufacturer uses what is sometimes a
57completely different programming interface, leading to a lot of different,
58sometimes very similar, Ethernet drivers. Of course, always using the same
59programming interface also means that when high-performance hardware
60facilities like PCI bus mastering DMA appear, it's hard to take advantage of
61them. Let's not go into that.
62
63One thing that makes ARCnet cards difficult to program for, however, is the
64limit on their packet sizes; standard ARCnet can only send packets that are
65up to 508 bytes in length. This is smaller than the Internet "bare minimum"
66of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
67level of encapsulation is defined by RFC1201, which I call "packet
68splitting," that allows "virtual packets" to grow as large as 64K each,
69although they are generally kept down to the Ethernet-style 1500 bytes.
70

72advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

77CABLING ARCNET NETWORKS
78-----------------------
79
80This section was rewritten by
81 Vojtech Pavlik <vojtech@suse.cz>
82using information from several people, including:
83 Avery Pennraun <apenwarr@worldvisions.ca>
84 Stephen A. Wood <saw@hallc1.cebaf.gov>
85 John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
86 Joachim Koenig <jojo@repas.de>
87and Avery touched it up a bit, at Vojtech's request.
88
89ARCnet (the classic 2.5 Mbps version) can be connected by two different
90types of cabling: coax and twisted pair. The other ARCnet-type networks
91(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
92cabling (Type1, Fiber, C1, C4, C5).
93
94For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
95also work fine, because ARCnet is a very stable network. I personally use 75
96Ohm TV antenna cable.
97
98Cards for coax cabling are shipped in two different variants: for BUS and
99STAR network topologies. They are mostly the same. The only difference
100lies in the hybrid chip installed. BUS cards use high impedance output,
101while STAR use low impedance. Low impedance card (STAR) is electrically
102equal to a high impedance one with a terminator installed.
103
104Usually, the ARCnet networks are built up from STAR cards and hubs. There
105are two types of hubs - active and passive. Passive hubs are small boxes
106with four BNC connectors containing four 47 Ohm resistors:
107
108 | | wires
109 R + junction
110-R-+-R- R 47 Ohm resistors
111 R
112 |
113
114The shielding is connected together. Active hubs are much more complicated;
115they are powered and contain electronics to amplify the signal and send it
116to other segments of the net. They usually have eight connectors. Active
117hubs come in two variants - dumb and smart. The dumb variant just
118amplifies, but the smart one decodes to digital and encodes back all packets
119coming through. This is much better if you have several hubs in the net,
120since many dumb active hubs may worsen the signal quality.
121
122And now to the cabling. What you can connect together:
123
1241. A card to a card. This is the simplest way of creating a 2-computer
125 network.
126
1272. A card to a passive hub. Remember that all unused connectors on the hub
128 must be properly terminated with 93 Ohm (or something else if you don't
129 have the right ones) terminators.
130 (Avery's note: oops, I didn't know that. Mine (TV cable) works
131 anyway, though.)
132
1333. A card to an active hub. Here is no need to terminate the unused
134 connectors except some kind of aesthetic feeling. But, there may not be
135 more than eleven active hubs between any two computers. That of course
136 doesn't limit the number of active hubs on the network.
137
1384. An active hub to another.
139
1405. An active hub to passive hub.
141
142Remember, that you can not connect two passive hubs together. The power loss
143implied by such a connection is too high for the net to operate reliably.
144
145An example of a typical ARCnet network:
146
147 R S - STAR type card
148 S------H--------A-------S R - Terminator
149 | | H - Hub
150 | | A - Active hub
151 | S----H----S
152 S |
153 |
154 S
155
156The BUS topology is very similar to the one used by Ethernet. The only
157difference is in cable and terminators: they should be 93 Ohm. Ethernet
158uses 50 Ohm impedance. You use T connectors to put the computers on a single
159line of cable, the bus. You have to put terminators at both ends of the
160cable. A typical BUS ARCnet network looks like:
161
162 RT----T------T------T------T------TR
163 B B B B B B
164
165 B - BUS type card
166 R - Terminator
167 T - T connector
168
169But that is not all! The two types can be connected together. According to
170the official documentation the only way of connecting them is using an active
171hub:
172
173 A------T------T------TR
174 | B B B
175 S---H---S
176 |
177 S
178
179The official docs also state that you can use STAR cards at the ends of
180BUS network in place of a BUS card and a terminator:
181
182 S------T------T------S
183 B B
184
185But, according to my own experiments, you can simply hang a BUS type card
186anywhere in middle of a cable in a STAR topology network. And more - you
187can use the bus card in place of any star card if you use a terminator. Then
188you can build very complicated networks fulfilling all your needs! An
189example:
190
191 S
192 |
193 RT------T-------T------H------S
194 B B B |
195 | R
196 S------A------T-------T-------A-------H------TR
197 | B B | | B
198 | S BT |
199 | | | S----A-----S
200 S------H---A----S | |
201 | | S------T----H---S |
202 S S B R S
203
204A basically different cabling scheme is used with Twisted Pair cabling. Each
205of the TP cards has two RJ (phone-cord style) connectors. The cards are
206then daisy-chained together using a cable connecting every two neighboring
207cards. The ends are terminated with RJ 93 Ohm terminators which plug into
208the empty connectors of cards on the ends of the chain. An example:
209
210 ___________ ___________
211 _R_|_ _|_|_ _|_R_
212 | | | | | |
213 |Card | |Card | |Card |
214 |_____| |_____| |_____|
215
216
217There are also hubs for the TP topology. There is nothing difficult
218involved in using them; you just connect a TP chain to a hub on any end or
219even at both. This way you can create almost any network configuration.
220The maximum of 11 hubs between any two computers on the net applies here as
221well. An example:
222
223 RP-------P--------P--------H-----P------P-----PR
224 |
225 RP-----H--------P--------H-----P------PR
226 | |
227 PR PR
228
229 R - RJ Terminator
230 P - TP Card
231 H - TP Hub
232
233Like any network, ARCnet has a limited cable length. These are the maximum
234cable lengths between two active ends (an active end being an active hub or
235a STAR card).
236
237 RG-62 93 Ohm up to 650 m
238 RG-59/U 75 Ohm up to 457 m
239 RG-11/U 75 Ohm up to 533 m
240 IBM Type 1 150 Ohm up to 200 m
241 IBM Type 3 100 Ohm up to 100 m
242
243The maximum length of all cables connected to a passive hub is limited to 65
244meters for RG-62 cabling; less for others. You can see that using passive
245hubs in a large network is a bad idea. The maximum length of a single "BUS
246Trunk" is about 300 meters for RG-62. The maximum distance between the two
247most distant points of the net is limited to 3000 meters. The maximum length
248of a TP cable between two cards/hubs is 650 meters.
249
250
251SETTING THE JUMPERS
252-------------------
253
254All ARCnet cards should have a total of four or five different settings:
255
256 - the I/O address: this is the "port" your ARCnet card is on. Probed
257 values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
258 your card has additional ones, which is possible, please tell me.) This
259 should not be the same as any other device on your system. According to
260 a doc I got from Novell, MS Windows prefers values of 0x300 or more,
261 eating net connections on my system (at least) otherwise. My guess is
262 this may be because, if your card is at 0x2E0, probing for a serial port
263 at 0x2E8 will reset the card and probably mess things up royally.
264 - Avery's favourite: 0x300.
265
266 - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
267 on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
268
269 Make sure this is different from any other card on your system. Note
270 that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
271 "cat /proc/interrupts" for a somewhat complete list of which ones are in
272 use at any given time. Here is a list of common usages from Vojtech
273 Pavlik <vojtech@suse.cz>:
274 ("Not on bus" means there is no way for a card to generate this
275 interrupt)
276 IRQ 0 - Timer 0 (Not on bus)
277 IRQ 1 - Keyboard (Not on bus)
278 IRQ 2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
279 IRQ 3 - COM2
280 IRQ 4 - COM1
281 IRQ 5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
282 IRQ 6 - Floppy disk controller
283 IRQ 7 - FREE (LPT1 if you don't use the polling driver; PLIP)
284 IRQ 8 - Realtime Clock Interrupt (Not on bus)
285 IRQ 9 - FREE (VGA vertical sync interrupt if enabled)
286 IRQ 10 - FREE
287 IRQ 11 - FREE
288 IRQ 12 - FREE
289 IRQ 13 - Numeric Coprocessor (Not on bus)
290 IRQ 14 - Fixed Disk Controller
291 IRQ 15 - FREE (Fixed Disk Controller 2 if you have it)
292
293 Note: IRQ 9 is used on some video cards for the "vertical retrace"
294 interrupt. This interrupt would have been handy for things like
295 video games, as it occurs exactly once per screen refresh, but
296 unfortunately IBM cancelled this feature starting with the original
297 VGA and thus many VGA/SVGA cards do not support it. For this
298 reason, no modern software uses this interrupt and it can almost
299 always be safely disabled, if your video card supports it at all.
300
301 If your card for some reason CANNOT disable this IRQ (usually there
302 is a jumper), one solution would be to clip the printed circuit
303 contact on the board: it's the fourth contact from the left on the
304 back side. I take no responsibility if you try this.
305
306 - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
307
308 - the memory address: Unlike most cards, ARCnets use "shared memory" for
309 copying buffers around. Make SURE it doesn't conflict with any other
310 used memory in your system!
311 A0000 - VGA graphics memory (ok if you don't have VGA)
312 B0000 - Monochrome text mode
313 C0000 \ One of these is your VGA BIOS - usually C0000.
314 E0000 /
315 F0000 - System BIOS
316
317 Anything less than 0xA0000 is, well, a BAD idea since it isn't above
318 640k.
319 - Avery's favourite: 0xD0000
320
321 - the station address: Every ARCnet card has its own "unique" network
322 address from 0 to 255. Unlike Ethernet, you can set this address
323 yourself with a jumper or switch (or on some cards, with special
324 software). Since it's only 8 bits, you can only have 254 ARCnet cards
325 on a network. DON'T use 0 or 255, since these are reserved (although
326 neat stuff will probably happen if you DO use them). By the way, if you
327 haven't already guessed, don't set this the same as any other ARCnet on
328 your network!
329 - Avery's favourite: 3 and 4. Not that it matters.
330
331 - There may be ETS1 and ETS2 settings. These may or may not make a
332 difference on your card (many manuals call them "reserved"), but are
333 used to change the delays used when powering up a computer on the
334 network. This is only necessary when wiring VERY long range ARCnet
335 networks, on the order of 4km or so; in any case, the only real
336 requirement here is that all cards on the network with ETS1 and ETS2
337 jumpers have them in the same position. Chris Hindy <chrish@io.org>
338 sent in a chart with actual values for this:
339 ET1 ET2 Response Time Reconfiguration Time
340 --- --- ------------- --------------------
341 open open 74.7us 840us
342 open closed 283.4us 1680us
343 closed open 561.8us 1680us
344 closed closed 1118.6us 1680us
345
346 Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
347 network.
348
349Also, on many cards (not mine, though) there are red and green LED's.
350Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean:
351 GREEN RED Status
352 ----- --- ------
353 OFF OFF Power off
354 OFF Short flashes Cabling problems (broken cable or not
355 terminated)
356 OFF (short) ON Card init
357 ON ON Normal state - everything OK, nothing
358 happens
359 ON Long flashes Data transfer
360 ON OFF Never happens (maybe when wrong ID)
361
362
363The following is all the specific information people have sent me about
364their own particular ARCnet cards. It is officially a mess, and contains
365huge amounts of duplicated information. I have no time to fix it. If you
366want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
367
368The model # is listed right above specifics for that card, so you should be
369able to use your text viewer's "search" function to find the entry you want.
370If you don't KNOW what kind of card you have, try looking through the
371various diagrams to see if you can tell.
372
373If your model isn't listed and/or has different settings, PLEASE PLEASE
374tell me. I had to figure mine out without the manual, and it WASN'T FUN!
375
376Even if your ARCnet model isn't listed, but has the same jumpers as another
377model that is, please e-mail me to say so.

551The PC130E is an enhanced version of the PC130 board, is equipped with a
552standard BNC female connector for connection to RG-62/U coax cable.
553Since this board is designed both for point-to-point connection in star
554networks and for connection to bus networks, it is downwardly compatible
555with all the other standard boards designed for coax networks (that is,
556the PC120, PC110 and PC100 star topology boards and the PC220, PC210 and
557PC200 bus topology boards).
558
559The PC270E is an enhanced version of the PC260 board, is equipped with two
560modular RJ11-type jacks for connection to twisted pair wiring.
561It can be used in a star or a daisy-chained network.

607
608
609Setting the Node ID
610-------------------
611
612The eight switches in group S2 are used to set the node ID.
613These switches work in a way similar to the PC100-series cards; see that
614entry for more information.
615
616
617Setting the I/O Base Address
618----------------------------
619
620The first three switches in switch group S1 are used to select one
621of eight possible I/O Base addresses using the following table
622
623
624 Switch | Hex I/O
625 1 2 3 | Address
626 -------|--------
627 0 0 0 | 260

635
636
637Setting the Base Memory (RAM) buffer Address
638--------------------------------------------
639
640The memory buffer requires 2K of a 16K block of RAM. The base of this
64116K block can be located in any of eight positions.
642Switches 4-6 of switch group S1 select the Base of the 16K block.
643Within that 16K address space, the buffer may be assigned any one of four
644positions, determined by the offset, switches 7 and 8 of group S1.

689*) To enable the 8K Boot PROM install the jumper ROM.
690 The default is jumper ROM not installed.
691
692
693Setting the Timeouts and Interrupt
694----------------------------------
695
696The jumpers labeled EXT1 and EXT2 are used to determine the timeout
697parameters. These two jumpers are normally left open.
698
699To select a hardware interrupt level set one (only one!) of the jumpers
700IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
701
702
703Configuring the PC130E for Star or Bus Topology
704-----------------------------------------------
705
706The single jumper labeled STAR is used to configure the PC130E board for
707star or bus topology.
708When the jumper is installed, the board may be used in a star network, when
709it is removed, the board can be used in a bus topology.
710
711
712Diagnostic LEDs
713---------------
714
715Two diagnostic LEDs are visible on the rear bracket of the board.
716The green LED monitors the network activity: the red one shows the
717board activity:
718
719 Green | Status Red | Status
720 -------|------------------- ---------|-------------------
721 on | normal activity flash/on | data transfer
722 blink | reconfiguration off | no data transfer;
723 off | defective board or | incorrect memory or
724 | node ID is zero | I/O address

736=====================================================================
737
738Note: There is another Version of the PC500 called Short Version, which
739 is different in hard- and software! The most important differences
740 are:
741 - The long board has no Shared memory.
742 - On the long board the selection of the interrupt is done by binary
743 coded switch, on the short board directly by jumper.
744
745[Avery's note: pay special attention to that: the long board HAS NO SHARED
746MEMORY. This means the current Linux-ARCnet driver can't use these cards.
747I have obtained a PC500Longboard and will be doing some experiments on it in
748the future, but don't hold your breath. Thanks again to Juergen Seifert for
749his advice about this!]

817Setting the Node ID
818-------------------
819
820The eight switches in group SW3 are used to set the node ID. Each node
821attached to the network must have an unique node ID which must be
822different from 0.
823Switch 1 serves as the least significant bit (LSB).
824
825The node ID is the sum of the values of all switches set to "1"
826These values are:
827
828 Switch | Value
829 -------|-------
830 1 | 1
831 2 | 2

858Setting the I/O Base Address
859----------------------------
860
861The first six switches in switch group SW1 are used to select one
862of 32 possible I/O Base addresses using the following table
863
864 Switch | Hex I/O
865 6 5 4 3 2 1 | Address

901Setting the Interrupt
902---------------------
903
904Switches seven through ten of switch group SW1 are used to select the
905interrupt level. The interrupt level is binary coded, so selections
906from 0 to 15 would be possible, but only the following eight values will
907be supported: 3, 4, 5, 7, 9, 10, 11, 12.
908
909 Switch | IRQ
910 10 9 8 7 |
911 ---------|--------
912 0 0 1 1 | 3
913 0 1 0 0 | 4
914 0 1 0 1 | 5
915 0 1 1 1 | 7
916 1 0 0 1 | 9 (=2) (default)
917 1 0 1 0 | 10
918 1 0 1 1 | 11
919 1 1 0 0 | 12
920
921
922Setting the Timeouts
923--------------------
924
925The two jumpers JP2 (1-4) are used to determine the timeout parameters.
926These two jumpers are normally left open.
927Refer to the COM9026 Data Sheet for alternate configurations.
928
929
930Configuring the PC500 for Star or Bus Topology
931----------------------------------------------
932
933The single jumper labeled JP6 is used to configure the PC500 board for
934star or bus topology.
935When the jumper is installed, the board may be used in a star network, when
936it is removed, the board can be used in a bus topology.
937
938
939Diagnostic LEDs
940---------------
941
942Two diagnostic LEDs are visible on the rear bracket of the board.
943The green LED monitors the network activity: the red one shows the
944board activity:
945
946 Green | Status Red | Status
947 -------|------------------- ---------|-------------------
948 on | normal activity flash/on | data transfer
949 blink | reconfiguration off | no data transfer;
950 off | defective board or | incorrect memory or

960
961Note: this data is gathered by experimenting and looking at info of other
962cards. However, I'm sure I got 99% of the settings right.
963
964The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
965LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing:

985
986The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
987labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
988IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
989
990S1 and S2 perform the same function as on the PC270, only their numbers
991are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
992
993I know it works when connected to a PC110 type ARCnet board.

1001 - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
1002 - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
1003 LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
1004 only (the JP0 jumper is hardwired), and BNC only.
1005
1006This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
1007nowhere else, not even on the few Xeroxed sheets from the manual).

1111PDI507 (8-bit card)
1112--------------------
1113 - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
1114 - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
1115 are mostly the same as this. PDI508Plus cards appear to be mainly
1116 software-configured.
1117
1118Jumpers:
1119 There is a jumper array at the bottom of the card, near the edge
1120 connector. This array is labelled J1. They control the IRQs and
1121 something else. Put only one jumper on the IRQ pins.
1122
1123 ETS1, ETS2 are for timing on very long distance networks. See the
1124 more general information near the top of this file.
1125
1126 There is a J2 jumper on two pins. A jumper should be put on them,
1127 since it was already there when I got the card. I don't know what
1128 this jumper is for though.
1129
1130 There is a two-jumper array for J3. I don't know what it is for,
1131 but there were already two jumpers on it when I got the card. It's
1132 a six pin grid in a two-by-three fashion. The jumpers were
1133 configured as follows:

1155
1156 - If using coax cable in a bus topology the J4 jumper must be removed;
1157 place it on one pin.
1158
1159 - If using bus topology with twisted pair wiring move the J3
1160 jumpers so they connect the middle pin and the pins closest to the RJ11
1161 Connectors. Also the J4 jumper must be removed; place it on one pin of
1162 J4 jumper for storage.
1163
1164 - If using star topology with twisted pair wiring move the J3
1165 jumpers so they connect the middle pin and the pins closest to the RJ11
1166 connectors.
1167
1168
1169DIP Switches:
1170
1171 The DIP switches accessible on the accessible end of the card while
1172 it is installed, is used to set the ARCnet address. There are 8
1173 switches. Use an address from 1 to 254.
1174
1175 Switch No.
1176 12345678 ARCnet address
1177 -----------------------------------------
1178 00000000 FF (Don't use this!)
1179 00000001 FE
1180 00000010 FD
1181 ....
1182 11111101 2
1183 11111110 1
1184 11111111 0 (Don't use this!)
1185
1186 There is another array of eight DIP switches at the top of the
1187 card. There are five labelled MS0-MS4 which seem to control the
1188 memory address, and another three labelled IO0-IO2 which seem to
1189 control the base I/O address of the card.
1190
1191 This was difficult to test by trial and error, and the I/O addresses
1192 are in a weird order. This was tested by setting the DIP switches,
1193 rebooting the computer, and attempting to load ARCETHER at various
1194 addresses (mostly between 0x200 and 0x400). The address that caused
1195 the red transmit LED to blink, is the one that I thought works.
1196
1197 Also, the address 0x3D0 seem to have a special meaning, since the
1198 ARCETHER packet driver loaded fine, but without the red LED
1199 blinking. I don't know what 0x3D0 is for though. I recommend using
1200 an address of 0x300 since Windows may not like addresses below
1201 0x300.
1202
1203 IO Switch No.
1204 210 I/O address
1205 -------------------------------
1206 111 0x260
1207 110 0x290
1208 101 0x2E0
1209 100 0x2F0
1210 011 0x300
1211 010 0x350
1212 001 0x380
1213 000 0x3E0
1214
1215 The memory switches set a reserved address space of 0x1000 bytes
1216 (0x100 segment units, or 4k). For example if I set an address of
1217 0xD000, it will use up addresses 0xD000 to 0xD100.
1218
1219 The memory switches were tested by booting using QEMM386 stealth,
1220 and using LOADHI to see what address automatically became excluded
1221 from the upper memory regions, and then attempting to load ARCETHER
1222 using these addresses.
1223
1224 I recommend using an ARCnet memory address of 0xD000, and putting
1225 the EMS page frame at 0xC000 while using QEMM stealth mode. That
1226 way, you get contiguous high memory from 0xD100 almost all the way
1227 the end of the megabyte.
1228
1229 Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
1230 on my card. It could be malfunctioning on my card. Experiment with
1231 it ON first, and if it doesn't work, set it to OFF. (It may be a
1232 modifier for the 0x200 bit?)
1233
1234 MS Switch No.
1235 43210 Memory address
1236 --------------------------------
1237 00001 0xE100 (guessed - was not detected by QEMM)
1238 00011 0xE000 (guessed - was not detected by QEMM)
1239 00101 0xDD00

1332
1333
1334Setting the Node ID
1335-------------------
1336
1337The eight switches in SW2 are used to set the node ID. Each node attached
1338to the network must have an unique node ID which must be different from 0.
1339Switch 1 (ID0) serves as the least significant bit (LSB).
1340
1341The node ID is the sum of the values of all switches set to "1"
1342These values are:
1343
1344 Switch | Label | Value
1345 -------|-------|-------
1346 1 | ID0 | 1
1347 2 | ID1 | 2
1348 3 | ID2 | 4
1349 4 | ID3 | 8

1373
1374Setting the I/O Base Address
1375----------------------------
1376
1377The last three switches in switch block SW1 are used to select one
1378of eight possible I/O Base addresses using the following table
1379
1380
1381 Switch | Hex I/O
1382 6 7 8 | Address
1383 ------------|--------
1384 ON ON ON | 260
1385 OFF ON ON | 290
1386 ON OFF ON | 2E0 (Manufacturer's default)
1387 OFF OFF ON | 2F0
1388 ON ON OFF | 300
1389 OFF ON OFF | 350
1390 ON OFF OFF | 380
1391 OFF OFF OFF | 3E0
1392
1393
1394Setting the Base Memory (RAM) buffer Address
1395--------------------------------------------
1396
1397The memory buffer (RAM) requires 2K. The base of this buffer can be
1398located in any of eight positions. The address of the Boot Prom is
1399memory base + 8K or memory base + 0x2000.
1400Switches 1-5 of switch block SW1 select the Memory Base address.
1401
1402 Switch | Hex RAM | Hex ROM
1403 1 2 3 4 5 | Address | Address *)
1404 --------------------|---------|-----------
1405 ON ON ON ON ON | C0000 | C2000
1406 ON ON OFF ON ON | C4000 | C6000
1407 ON ON ON OFF ON | CC000 | CE000
1408 ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
1409 ON ON ON ON OFF | D4000 | D6000
1410 ON ON OFF ON OFF | D8000 | DA000
1411 ON ON ON OFF OFF | DC000 | DE000
1412 ON ON OFF OFF OFF | E0000 | E2000
1413
1414*) To enable the Boot ROM install the jumper JP1
1415
1416Note: Since the switches 1 and 2 are always set to ON it may be possible
1417 that they can be used to add an offset of 2K, 4K or 6K to the base
1418 address, but this feature is not documented in the manual and I
1419 haven't tested it yet.
1420
1421
1422Setting the Interrupt Line
1423--------------------------
1424
1425To select a hardware interrupt level install one (only one!) of the jumpers
1426JP2, JP3, JP4, JP5, JP6. JP2 is the default.

1549Switch 1 (ID0) serves as the least significant bit (LSB).
1550
1551The node ID is the sum of the values of all switches set to "1"
1552These values are:
1553
1554 Switch | Label | Value
1555 -------|-------|-------
1556 1 | ID0 | 1
1557 2 | ID1 | 2
1558 3 | ID2 | 4
1559 4 | ID3 | 8
1560 5 | ID4 | 16
1561 6 | ID5 | 32
1562 7 | ID6 | 64
1563 8 | ID7 | 128
1564

1584Setting the I/O Base Address
1585----------------------------
1586
1587The first six switches in switch block SW1 are used to select the I/O Base
1588address using the following table:
1589
1590 Switch | Hex I/O
1591 1 2 3 4 5 6 | Address
1592 ------------------------|--------
1593 OFF ON ON OFF OFF ON | 260
1594 OFF ON OFF ON ON OFF | 290
1595 OFF ON OFF OFF OFF ON | 2E0 (Manufacturer's default)
1596 OFF ON OFF OFF OFF OFF | 2F0
1597 OFF OFF ON ON ON ON | 300
1598 OFF OFF ON OFF ON OFF | 350
1599 OFF OFF OFF ON ON ON | 380
1600 OFF OFF OFF OFF OFF ON | 3E0
1601
1602Note: Other IO-Base addresses seem to be selectable, but only the above
1603 combinations are documented.
1604
1605
1606Setting the Base Memory (RAM) buffer Address
1607--------------------------------------------
1608
1609The switches 7-10 of switch block SW1 are used to select the Memory
1610Base address of the RAM (2K) and the PROM.
1611
1612 Switch | Hex RAM | Hex ROM
1613 7 8 9 10 | Address | Address
1614 ----------------|---------|-----------
1615 OFF OFF ON ON | C0000 | C8000
1616 OFF OFF ON OFF | D0000 | D8000 (Default)
1617 OFF OFF OFF ON | E0000 | E8000
1618
1619Note: Other MEM-Base addresses seem to be selectable, but only the above
1620 combinations are documented.
1621
1622
1623Setting the Interrupt Line
1624--------------------------
1625
1626To select a hardware interrupt level install one (only one!) of the jumpers
1627JP3 through JP13 using the following table:
1628
1629 Jumper | IRQ
1630 -------|-----------------
1631 3 | 14
1632 4 | 15
1633 5 | 12
1634 6 | 11
1635 7 | 10
1636 8 | 3
1637 9 | 4
1638 10 | 5
1639 11 | 6
1640 12 | 7
1641 13 | 2 (=9) Default!
1642
1643Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
1644 Controller
1645 - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
1646 Hard Disk, it may conflict with their controllers
1647
1648
1649Setting the Timeout Parameters
1650------------------------------
1651
1652The jumpers labeled JP1 and JP2 are used to determine the timeout
1653parameters. These two jumpers are normally left open.

1706It seems that the bits are considered in reverse order. Also, you must
1707observe that some of those addresses are unusual and I didn't probe them; I
1708used a memory dump in DOS to identify them. For the 00000 configuration and
1709some others that I didn't write here the card seems to conflict with the
1710video card (an S3 GENDAC). I leave the full decoding of those addresses to
1711you.

1808Setting the Node ID
1809-------------------
1810
1811The eight switches in SW2 are used to set the node ID. Each node attached
1812to the network must have an unique node ID which must not be 0.
1813Switch 1 (ID0) serves as the least significant bit (LSB).
1814
1815Setting one of the switches to OFF means "1", ON means "0".
1816
1817The node ID is the sum of the values of all switches set to "1"
1818These values are:
1819
1820 Switch | Value
1821 -------|-------
1822 1 | 1
1823 2 | 2
1824 3 | 4
1825 4 | 8
1826 5 | 16
1827 6 | 32
1828 7 | 64
1829 8 | 128
1830
1831Don't set this to 0 or 255; these values are reserved.
1832
1833
1834Setting the I/O Base Address
1835----------------------------
1836
1837The switches 1 to 6 of switch block SW1 are used to select one
1838of 32 possible I/O Base addresses using the following tables
1839
1840 | Hex
1841 Switch | Value
1842 -------|-------
1843 1 | 200
1844 2 | 100
1845 3 | 80
1846 4 | 40
1847 5 | 20
1848 6 | 10
1849
1850The I/O address is sum of all switches set to "1". Remember that
1851the I/O address space bellow 0x200 is RESERVED for mainboard, so
1852switch 1 should be ALWAYS SET TO OFF.
1853
1854
1855Setting the Base Memory (RAM) buffer Address
1856--------------------------------------------
1857
1858The memory buffer (RAM) requires 2K. The base of this buffer can be
1859located in any of sixteen positions. However, the addresses below
1860A0000 are likely to cause system hang because there's main RAM.
1861
1862Jumpers 7-10 of switch block SW1 select the Memory Base address.
1863
1864 Switch | Hex RAM
1865 7 8 9 10 | Address
1866 ----------------|---------
1867 OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
1868 OFF OFF OFF ON | E0000
1869 OFF OFF ON OFF | D0000
1870 OFF OFF ON ON | C0000 (conflicts with video BIOS)
1871 OFF ON OFF OFF | B0000 (conflicts with mono video)
1872 OFF ON OFF ON | A0000 (conflicts with graphics)
1873
1874
1875Setting the Interrupt Line
1876--------------------------
1877
1878Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
1879shorted, OFF means open.
1880
1881 Jumper | IRQ
1882 1 2 3 4 5 |
1883 ----------------------------
1884 ON OFF OFF OFF OFF | 7
1885 OFF ON OFF OFF OFF | 5
1886 OFF OFF ON OFF OFF | 4
1887 OFF OFF OFF ON OFF | 3
1888 OFF OFF OFF OFF ON | 2
1889
1890
1891Unknown jumpers & sockets
1892-------------------------
1893
1894I know nothing about these. I just guess that J16&J17 are timeout
1895jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
1896J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
1897guess the purpose.

1994--------------------------------------------
1995
1996The memory buffer (RAM) requires 2K. The base of this buffer can be
1997located in any of eight positions. The address of the Boot Prom is
1998memory base + 0x2000.
1999Jumpers 3-5 of switch block SW1 select the Memory Base address.

2113Setting the I/O Base Address
2114----------------------------
2115
2116The last three switches in switch block SW1 are used to select one
2117of eight possible I/O Base addresses using the following table:
2118
2119
2120 Switch | Hex I/O
2121 6 7 8 | Address
2122 ------------|--------
2123 ON ON ON | 260 (Manufacturer's default)
2124 OFF ON ON | 290
2125 ON OFF ON | 2E0
2126 OFF OFF ON | 2F0
2127 ON ON OFF | 300
2128 OFF ON OFF | 350
2129 ON OFF OFF | 380
2130 OFF OFF OFF | 3E0
2131
2132
2133Setting the Base Memory (RAM) buffer Address
2134--------------------------------------------
2135
2136The memory buffer (RAM) requires 2K. The base of this buffer can be
2137located in any of eight positions. The address of the Boot Prom is
2138memory base + 0x2000.
2139Jumpers 3-5 of switch block SW1 select the Memory Base address.
2140
2141 Switch | Hex RAM | Hex ROM
2142 1 2 3 4 5 | Address | Address *)
2143 --------------------|---------|-----------
2144 ON ON ON ON ON | C0000 | C2000
2145 ON ON OFF ON ON | C4000 | C6000 (Manufacturer's default)
2146 ON ON ON OFF ON | CC000 | CE000
2147 ON ON OFF OFF ON | D0000 | D2000
2148 ON ON ON ON OFF | D4000 | D6000
2149 ON ON OFF ON OFF | D8000 | DA000
2150 ON ON ON OFF OFF | DC000 | DE000
2151 ON ON OFF OFF OFF | E0000 | E2000
2152
2153*) To enable the Boot ROM short the jumper J2.
2154
2155The jumpers 1 and 2 probably add 0x0800 and 0x1000 to RAM address.
2156
2157
2158Setting the Interrupt Line
2159--------------------------
2160
2161Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
2162shorted, OFF means open.
2163
2164 Jumper | IRQ
2165 1 2 3 4 5 |
2166 ----------------------------
2167 ON OFF OFF OFF OFF | 2
2168 OFF ON OFF OFF OFF | 3
2169 OFF OFF ON OFF OFF | 4
2170 OFF OFF OFF ON OFF | 5
2171 OFF OFF OFF OFF ON | 7
2172
2173
2174Setting the Timeout Parameters
2175------------------------------
2176
2177The jumpers J3 are used to set the timeout parameters. These two
2178jumpers are normally left open.

2252
2253There is a DIP-switch with 8 switches, used to set the shared memory address
2254to be used. The first 6 switches set the address, the 7th doesn't have any
2255function, and the 8th switch is used to select "compatible" or "enhanced".
2256When I got my two cards, one of them had this switch set to "enhanced". That
2257card didn't work at all, it wasn't even recognized by the driver. The other
2258card had this switch set to "compatible" and it behaved absolutely normally. I
2259guess that the switch on one of the cards, must have been changed accidentally
2260when the card was taken out of its former host. The question remains
2261unanswered, what is the purpose of the "enhanced" position?
2262
2263[Avery's note: "enhanced" probably either disables shared memory (use IO
2264ports instead) or disables IO ports (use memory addresses instead). This
2265varies by the type of card involved. I fail to see how either of these
2266enhance anything. Send me more detailed information about this mode, or
2267just use "compatible" mode instead.]

2276
2277[Avery's note: these don't work with my driver for some reason. These cards
2278SEEM to have settings similar to the PDI508Plus, which is
2279software-configured and doesn't work with my driver either. The "Waterloo
2280chip" is a boot PROM, probably designed specifically for the University of
2281Waterloo. If you have any further information about this card, please
2282e-mail me.]
2283
2284The probe has not been able to detect the card on any of the J2 settings,
2285and I tried them again with the "Waterloo" chip removed.

2433
2434
2435Setting the Node ID
2436-------------------
2437
2438The eight switches in group SW1 are used to set the node ID.
2439Each node attached to the network must have an unique node ID which
2440must be different from 0.
2441Switch 8 serves as the least significant bit (LSB).
2442
2443The node ID is the sum of the values of all switches set to "1"
2444These values are:
2445
2446 Switch | Value
2447 -------|-------
2448 8 | 1
2449 7 | 2
2450 6 | 4
2451 5 | 8

2474
2475
2476Setting the I/O Base Address
2477----------------------------
2478
2479The first three switches in switch group SW2 are used to select one
2480of eight possible I/O Base addresses using the following table
2481
2482 Switch | Hex I/O
2483 1 2 3 | Address
2484 ------------|--------
2485 ON ON ON | 260
2486 ON ON OFF | 290
2487 ON OFF ON | 2E0 (Manufacturer's default)
2488 ON OFF OFF | 2F0
2489 OFF ON ON | 300
2490 OFF ON OFF | 350
2491 OFF OFF ON | 380
2492 OFF OFF OFF | 3E0
2493
2494
2495Setting the Base Memory (RAM) buffer Address
2496--------------------------------------------
2497
2498The memory buffer requires 2K of a 16K block of RAM. The base of this
249916K block can be located in any of eight positions.
2500Switches 4-6 of switch group SW2 select the Base of the 16K block.
2501Within that 16K address space, the buffer may be assigned any one of four
2502positions, determined by the offset, switches 7 and 8 of group SW2.

2547*) To enable the 8K Boot PROM install the jumper ROM.
2548 The default is jumper ROM not installed.
2549
2550
2551Setting Interrupt Request Lines (IRQ)
2552-------------------------------------
2553
2554To select a hardware interrupt level set one (only one!) of the jumpers
2555IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
2556
2557
2558Setting the Timeouts
2559--------------------
2560
2561The two jumpers labeled ET1 and ET2 are used to determine the timeout
2562parameters (response and reconfiguration time). Every node in a network
2563must be set to the same timeout values.
2564
2565 ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
2566 --------|--------------------|--------------------------
2567 Off Off | 78 | 840 (Default)
2568 Off On | 285 | 1680
2569 On Off | 563 | 1680
2570 On On | 1130 | 1680
2571
2572On means jumper installed, Off means jumper not installed

2575NONAME 16-BIT ARCNET
2576====================
2577
2578The manual of my 8-Bit NONAME ARCnet Card contains another description
2579of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
2580because there are missing two pages in the manual booklet. (The table
2581of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
2582the booklet there is a different way of counting ... 2-9, 2-10, A-1,
2583(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
2584Also the picture of the board layout is not as good as the picture of
25858-Bit card, because there isn't any letter like "SW1" written to the
2586picture.
2587Should somebody have such a board, please feel free to complete this
2588description or to send a mail to me!

2621Setting one of the switches to Off means "1", On means "0".
2622
2623
2624Setting the Node ID
2625-------------------
2626
2627The eight switches in group SW2 are used to set the node ID.
2628Each node attached to the network must have an unique node ID which
2629must be different from 0.
2630Switch 8 serves as the least significant bit (LSB).
2631
2632The node ID is the sum of the values of all switches set to "1"
2633These values are:
2634
2635 Switch | Value
2636 -------|-------
2637 8 | 1
2638 7 | 2
2639 6 | 4

2665Setting the I/O Base Address
2666----------------------------
2667
2668The first three switches in switch group SW1 are used to select one
2669of eight possible I/O Base addresses using the following table
2670
2671 Switch | Hex I/O
2672 3 2 1 | Address
2673 ------------|--------

2683
2684Setting the Base Memory (RAM) buffer Address
2685--------------------------------------------
2686
2687The memory buffer requires 2K of a 16K block of RAM. The base of this
268816K block can be located in any of eight positions.
2689Switches 6-8 of switch group SW1 select the Base of the 16K block.
2690Within that 16K address space, the buffer may be assigned any one of four
2691positions, determined by the offset, switches 4 and 5 of group SW1.

2755
2756I have named this ARCnet card "NONAME", since I got only the card with
2757no manual at all and the only text identifying the manufacturer is
2758"MADE IN TAIWAN R.O.C" printed on the card.

2797Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
2798switches.
2799
2800Setting the jumpers to ON means connecting the upper two pins, off the bottom
2801two - or - in case of IRQ setting, connecting none of them at all.
2802
2803Setting the Node ID
2804-------------------
2805
2806The eight switches in SW2 are used to set the node ID. Each node attached
2807to the network must have an unique node ID which must not be 0.
2808Switch 1 (ID0) serves as the least significant bit (LSB).
2809
2810Setting one of the switches to Off means "1", On means "0".
2811
2812The node ID is the sum of the values of all switches set to "1"
2813These values are:
2814
2815 Switch | Label | Value
2816 -------|-------|-------
2817 1 | ID0 | 1
2818 2 | ID1 | 2

2845Setting the I/O Base Address
2846----------------------------
2847
2848The last three switches in switch block SW1 are used to select one
2849of eight possible I/O Base addresses using the following table
2850
2851
2852 Switch | Hex I/O
2853 6 7 8 | Address

2862 OFF OFF OFF | 3E0
2863
2864
2865Setting the Base Memory (RAM) buffer Address
2866--------------------------------------------
2867
2868The memory buffer (RAM) requires 2K. The base of this buffer can be
2869located in any of eight positions. The address of the Boot Prom is
2870memory base + 0x2000.
2871Jumpers 3-5 of jumper block SW1 select the Memory Base address.
2872
2873 Switch | Hex RAM | Hex ROM
2874 1 2 3 4 5 | Address | Address *)
2875 --------------------|---------|-----------
2876 ON ON ON ON ON | C0000 | C2000
2877 ON ON OFF ON ON | C4000 | C6000
2878 ON ON ON OFF ON | CC000 | CE000
2879 ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
2880 ON ON ON ON OFF | D4000 | D6000
2881 ON ON OFF ON OFF | D8000 | DA000
2882 ON ON ON OFF OFF | DC000 | DE000
2883 ON ON OFF OFF OFF | E0000 | E2000
2884
2885*) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
2886
2887The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
2888
2889Setting the Interrupt Line
2890--------------------------
2891
2892Jumpers 1-5 of the jumper block SW3 control the IRQ level.

2967up (on) SW1...(switches 1-5)
2968IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
2969
2970The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
2971are used to determine the timeout parameters. These two dip switches
2972are normally left off (down).

3020Setting the Node ID
3021-------------------
3022
3023The eight switches in group SW3 are used to set the node ID.
3024Each node attached to the network must have an unique node ID which
3025must be different from 0.
3026Switch 1 serves as the least significant bit (LSB).
3027switches in the DOWN position are OFF (0) and in the UP position are ON (1)
3028
3029The node ID is the sum of the values of all switches set to "1"
3030These values are:
3031 Switch | Value
3032 -------|-------
3033 1 | 1
3034 2 | 2
