MCC		 21Introduction to ARCnet
22======================
1da177e4
LT		 23
24ARCnet is a network type which works in a way similar to popular Ethernet
25networks but which is also different in some very important ways.
26
27First 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,
29there are others as well, but these are less common. The different hardware
30types, as far as I'm aware, are not compatible and so you cannot wire a
31100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
32work with 100 Mbps cards, but I haven't been able to verify this myself,
33since I only have the 2.5 Mbps variety. It is probably not going to saturate
34your 100 Mbps card. Stop complaining. :)
35
36You also cannot connect an ARCnet card to any kind of Ethernet card and
aa92320b 37expect it to work.
1da177e4
LT		 38
39There are two "types" of ARCnet - STAR topology and BUS topology. This
40refers to how the cards are meant to be wired together. According to most
41available documentation, you can only connect STAR cards to STAR cards and
42BUS cards to BUS cards. That makes sense, right? Well, it's not quite
43true; see below under "Cabling."
44
45Once you get past these little stumbling blocks, ARCnet is actually quite a
46well-designed standard. It uses something called "modified token passing"
47which makes it completely incompatible with so-called "Token Ring" cards,
48but which makes transfers much more reliable than Ethernet does. In fact,
49ARCnet will guarantee that a packet arrives safely at the destination, and
50even if it can't possibly be delivered properly (ie. because of a cable
51break, or because the destination computer does not exist) it will at least
52tell the sender about it.
53
54Because of the carefully defined action of the "token", it will always make
55a pass around the "ring" within a maximum length of time. This makes it
56useful for realtime networks.
57
58In addition, all known ARCnet cards have an (almost) identical programming
59interface. This means that with one ARCnet driver you can support any
60card, whereas with Ethernet each manufacturer uses what is sometimes a
61completely different programming interface, leading to a lot of different,
62sometimes very similar, Ethernet drivers. Of course, always using the same
63programming interface also means that when high-performance hardware
64facilities like PCI bus mastering DMA appear, it's hard to take advantage of
65them. Let's not go into that.
66
67One thing that makes ARCnet cards difficult to program for, however, is the
68limit on their packet sizes; standard ARCnet can only send packets that are
69up to 508 bytes in length. This is smaller than the Internet "bare minimum"
70of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
71level of encapsulation is defined by RFC1201, which I call "packet
72splitting," that allows "virtual packets" to grow as large as 64K each,
73although they are generally kept down to the Ethernet-style 1500 bytes.
74
75For more information on the advantages and disadvantages (mostly the
76advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

1da177e4 89using information from several people, including:

LT		 96and Avery touched it up a bit, at Vojtech's request.
97
98ARCnet (the classic 2.5 Mbps version) can be connected by two different
99types 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
101cabling (Type1, Fiber, C1, C4, C5).
102
103For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
104also work fine, because ARCnet is a very stable network. I personally use 75
105Ohm TV antenna cable.
106
107Cards for coax cabling are shipped in two different variants: for BUS and
108STAR network topologies. They are mostly the same. The only difference
109lies in the hybrid chip installed. BUS cards use high impedance output,
110while STAR use low impedance. Low impedance card (STAR) is electrically
111equal to a high impedance one with a terminator installed.
112
113Usually, the ARCnet networks are built up from STAR cards and hubs. There
114are two types of hubs - active and passive. Passive hubs are small boxes
aa92320b 115with four BNC connectors containing four 47 Ohm resistors::
1da177e4 116

118 R + junction
119 -R-+-R- R 47 Ohm resistors
120 R
121 |
1da177e4
LT		 122
123The shielding is connected together. Active hubs are much more complicated;
124they are powered and contain electronics to amplify the signal and send it
125to other segments of the net. They usually have eight connectors. Active
126hubs come in two variants - dumb and smart. The dumb variant just
127amplifies, but the smart one decodes to digital and encodes back all packets
128coming through. This is much better if you have several hubs in the net,
129since many dumb active hubs may worsen the signal quality.
130
131And now to the cabling. What you can connect together:
132
1331. A card to a card. This is the simplest way of creating a 2-computer
134 network.
135
1362. 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.
aa92320b
MCC		 139
140 (Avery's note: oops, I didn't know that. Mine (TV cable) works
1da177e4
LT		 141 anyway, though.)
142
1433. 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.
aa92320b 147
1da177e4
LT		 1484. An active hub to another.
149
1505. An active hub to passive hub.
151
84eb8d06 152Remember that you cannot connect two passive hubs together. The power loss
1da177e4
LT		 153implied by such a connection is too high for the net to operate reliably.
154
aa92320b 155An example of a typical ARCnet network::
1da177e4 156

1da177e4
LT		 166The BUS topology is very similar to the one used by Ethernet. The only
167difference is in cable and terminators: they should be 93 Ohm. Ethernet
168uses 50 Ohm impedance. You use T connectors to put the computers on a single
169line of cable, the bus. You have to put terminators at both ends of the
aa92320b 170cable. A typical BUS ARCnet network looks like::

172 RT----T------T------T------T------TR
173 B B B B B B
174
175 B - BUS type card
176 R - Terminator
177 T - T connector
178
179But that is not all! The two types can be connected together. According to
180the official documentation the only way of connecting them is using an active
aa92320b 181hub::

189The official docs also state that you can use STAR cards at the ends of
aa92320b 190BUS network in place of a BUS card and a terminator::

192 S------T------T------S
aa92320b 193 B B
1da177e4
LT		 194
195But, according to my own experiments, you can simply hang a BUS type card
196anywhere in middle of a cable in a STAR topology network. And more - you
197can use the bus card in place of any star card if you use a terminator. Then
198you can build very complicated networks fulfilling all your needs! An

LT		 214A basically different cabling scheme is used with Twisted Pair cabling. Each
215of the TP cards has two RJ (phone-cord style) connectors. The cards are
216then daisy-chained together using a cable connecting every two neighboring
217cards. The ends are terminated with RJ 93 Ohm terminators which plug into
aa92320b 218the empty connectors of cards on the ends of the chain. An example::

1da177e4
LT		 225
226
227There are also hubs for the TP topology. There is nothing difficult
228involved in using them; you just connect a TP chain to a hub on any end or
aa92320b 229even at both. This way you can create almost any network configuration.
1da177e4 230The maximum of 11 hubs between any two computers on the net applies here as
aa92320b 231well. An example::

240 P - TP Card
241 H - TP Hub
242
243Like any network, ARCnet has a limited cable length. These are the maximum
244cable lengths between two active ends (an active end being an active hub or
245a STAR card).
246
aa92320b 247 ========== ======= ===========
1da177e4

252 IBM Type 3 100 Ohm up to 100 m
aa92320b 253 ========== ======= ===========
1da177e4
LT		 254
255The maximum length of all cables connected to a passive hub is limited to 65
256meters for RG-62 cabling; less for others. You can see that using passive
257hubs in a large network is a bad idea. The maximum length of a single "BUS
258Trunk" is about 300 meters for RG-62. The maximum distance between the two
259most distant points of the net is limited to 3000 meters. The maximum length
260of a TP cable between two cards/hubs is 650 meters.

MCC		 263Setting the Jumpers
264===================
1da177e4
LT		 265
266All ARCnet cards should have a total of four or five different settings:
267
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.
aa92320b 276
1da177e4
LT		 277 - Avery's favourite: 0x300.
278
279 - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
aa92320b
MCC		 280 on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
281
1da177e4
LT		 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 <vojtech@suse.cz>:
aa92320b
MCC		 287
288 ("Not on bus" means there is no way for a card to generate this
1da177e4 289 interrupt)
aa92320b
MCC		 290
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 ====== =========================================================
309
310
311 .. note::
312
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.
320
1da177e4
LT		 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.
325
326 - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
327
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!
aa92320b
MCC		 331
332 ::
333
1da177e4 334 A0000 - VGA graphics memory (ok if you don't have VGA)
aa92320b
MCC		 335 B0000 - Monochrome text mode
336 C0000 \ One of these is your VGA BIOS - usually C0000.
337 E0000 /
338 F0000 - System BIOS
1da177e4
LT		 339
340 Anything less than 0xA0000 is, well, a BAD idea since it isn't above
341 640k.
aa92320b 342
1da177e4
LT		 343 - Avery's favourite: 0xD0000
344
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!
aa92320b 353
1da177e4
LT		 354 - Avery's favourite: 3 and 4. Not that it matters.
355
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 <chrish@io.org>
363 sent in a chart with actual values for this:

477 - special thanks to Timo Hilbrink <timoh@xs4all.nl> for noting that PC120,
aa92320b 478 130, 500, and 600 all have the same switches as Avery's PC100.
1da177e4
LT		 479 PC500/600 have several extra, undocumented pins though. (?)
480 - PC110 settings were verified by Stephen A. Wood <saw@cebaf.gov>
481 - Also, the JP- and S-numbers probably don't match your card exactly. Try
482 to find jumpers/switches with the same number of settings - it's
483 probably more reliable.

aa92320b 724^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1da177e4 725
aa92320b 726The jumpers labeled EXT1 and EXT2 are used to determine the timeout
1da177e4
LT		 727parameters. These two jumpers are normally left open.
728

aa92320b 734^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1da177e4 735
aa92320b 736The single jumper labeled STAR is used to configure the PC130E board for
1da177e4 737star or bus topology.
aa92320b 738When the jumper is installed, the board may be used in a star network, when
1da177e4
LT		 739it is removed, the board can be used in a bus topology.

761
762
aa92320b 763 .. note::
1da177e4 764
aa92320b 765 There is another Version of the PC500 called Short Version, which
1da177e4
LT		 766 is different in hard- and software! The most important differences
767 are:
aa92320b 768
1da177e4
LT		 769 - The long board has no Shared memory.
770 - On the long board the selection of the interrupt is done by binary
aa92320b
MCC		 771 coded switch, on the short board directly by jumper.
772
1da177e4 773[Avery's note: pay special attention to that: the long board HAS NO SHARED
aa92320b 774MEMORY. This means the current Linux-ARCnet driver can't use these cards.
1da177e4
LT		 775I have obtained a PC500Longboard and will be doing some experiments on it in
776the future, but don't hold your breath. Thanks again to Juergen Seifert for
777his advice about this!]

aa92320b 961^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1da177e4 962
aa92320b 963The single jumper labeled JP6 is used to configure the PC500 board for
1da177e4 964star or bus topology.
aa92320b 965When the jumper is installed, the board may be used in a star network, when
1da177e4
LT		 966it is removed, the board can be used in a bus topology.
967

969Diagnostic LEDs
aa92320b 970^^^^^^^^^^^^^^^
1da177e4

992The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
aa92320b 993LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::

1014The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
1015labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
1016IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
1017
1018S1 and S2 perform the same function as on the PC270, only their numbers
1019are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
1020
1021I know it works when connected to a PC110 type ARCnet board.

1152 - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)

1154 software-configured.
1155
1156Jumpers:
aa92320b 1157
1da177e4 1158 There is a jumper array at the bottom of the card, near the edge
aa92320b
MCC		 1159 connector. This array is labelled J1. They control the IRQs and
1160 something else. Put only one jumper on the IRQ pins.
1da177e4
LT		 1161
1162 ETS1, ETS2 are for timing on very long distance networks. See the
1163 more general information near the top of this file.
1164
1165 There is a J2 jumper on two pins. A jumper should be put on them,
aa92320b
MCC		 1166 since it was already there when I got the card. I don't know what
1167 this jumper is for though.
1da177e4
LT		 1168
1169 There is a two-jumper array for J3. I don't know what it is for,
aa92320b
MCC		 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::

1195 - If using coax cable in a bus topology the J4 jumper must be removed;
1196 place it on one pin.
1197
aa92320b 1198 - If using bus topology with twisted pair wiring move the J3
1da177e4
LT		 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

1208DIP Switches:
1209
1210 The DIP switches accessible on the accessible end of the card while
aa92320b
MCC		 1211 it is installed, is used to set the ARCnet address. There are 8
1212 switches. Use an address from 1 to 254

aa92320b 1225 ========== =========================
1da177e4
LT		 1226
1227 There is another array of eight DIP switches at the top of the
aa92320b
MCC		 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.
1da177e4
LT		 1231
1232 This was difficult to test by trial and error, and the I/O addresses
aa92320b
MCC		 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.
1da177e4
LT		 1237
1238 Also, the address 0x3D0 seem to have a special meaning, since the
aa92320b
MCC		 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.

aa92320b 1256 ============= ===========
1da177e4
LT		 1257
1258 The memory switches set a reserved address space of 0x1000 bytes
aa92320b
MCC		 1259 (0x100 segment units, or 4k). For example if I set an address of
1260 0xD000, it will use up addresses 0xD000 to 0xD100.
1da177e4
LT		 1261
1262 The memory switches were tested by booting using QEMM386 stealth,
aa92320b
MCC		 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.
1da177e4
LT		 1266
1267 I recommend using an ARCnet memory address of 0xD000, and putting
aa92320b
MCC		 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.
1da177e4
LT		 1271
1272 Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
aa92320b
MCC		 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?)

1755It seems that the bits are considered in reverse order. Also, you must
1756observe that some of those addresses are unusual and I didn't probe them; I
1757used a memory dump in DOS to identify them. For the 00000 configuration and
1758some others that I didn't write here the card seems to conflict with the
1759video card (an S3 GENDAC). I leave the full decoding of those addresses to
1760you.

1862Setting the Node ID
aa92320b 1863^^^^^^^^^^^^^^^^^^^
1da177e4
LT		 1864
1865The eight switches in SW2 are used to set the node ID. Each node attached
1866to the network must have an unique node ID which must not be 0.
1867Switch 1 (ID0) serves as the least significant bit (LSB).
1868
1869Setting one of the switches to OFF means "1", ON means "0".
1870
1871The node ID is the sum of the values of all switches set to "1"
aa92320b 1872These values are::
1da177e4
LT		 1873
1874 Switch | Value
1875 -------|-------

1891The switches 1 to 6 of switch block SW1 are used to select one
aa92320b

1904The I/O address is sum of all switches set to "1". Remember that
a266ef69 1905the I/O address space below 0x200 is RESERVED for mainboard, so
aa92320b 1906switch 1 should be ALWAYS SET TO OFF.

1909Setting the Base Memory (RAM) buffer Address
aa92320b 1910^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1da177e4
LT		 1911
1912The memory buffer (RAM) requires 2K. The base of this buffer can be
1913located in any of sixteen positions. However, the addresses below
1914A0000 are likely to cause system hang because there's main RAM.
1915
aa92320b 1916Jumpers 7-10 of switch block SW1 select the Memory Base address::

aa92320b 1946^^^^^^^^^^^^^^^^^^^^^^^^^
1da177e4
LT		 1947
1948I know nothing about these. I just guess that J16&J17 are timeout
1949jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
1950J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
1951guess the purpose.

2323There is a DIP-switch with 8 switches, used to set the shared memory address
2324to be used. The first 6 switches set the address, the 7th doesn't have any
2325function, and the 8th switch is used to select "compatible" or "enhanced".
2326When I got my two cards, one of them had this switch set to "enhanced". That
2327card didn't work at all, it wasn't even recognized by the driver. The other
2328card had this switch set to "compatible" and it behaved absolutely normally. I
2329guess that the switch on one of the cards, must have been changed accidentally
2330when the card was taken out of its former host. The question remains
2331unanswered, what is the purpose of the "enhanced" position?
2332
2333[Avery's note: "enhanced" probably either disables shared memory (use IO
2334ports instead) or disables IO ports (use memory addresses instead). This
2335varies by the type of card involved. I fail to see how either of these
2336enhance anything. Send me more detailed information about this mode, or
2337just use "compatible" mode instead.]

2346[Avery's note: these don't work with my driver for some reason. These cards
2347SEEM to have settings similar to the PDI508Plus, which is
2348software-configured and doesn't work with my driver either. The "Waterloo
2349chip" is a boot PROM, probably designed specifically for the University of
2350Waterloo. If you have any further information about this card, please
2351e-mail me.]
2352
2353The probe has not been able to detect the card on any of the J2 settings,
2354and I tried them again with the "Waterloo" chip removed.

2510The eight switches in group SW1 are used to set the node ID.
2511Each node attached to the network must have an unique node ID which
2512must be different from 0.
2513Switch 8 serves as the least significant bit (LSB).
2514
aa92320b
MCC		 2515The node ID is the sum of the values of all switches set to "1"
2516These values are::

2570The memory buffer requires 2K of a 16K block of RAM. The base of this
257116K block can be located in any of eight positions.
2572Switches 4-6 of switch group SW2 select the Base of the 16K block.
2573Within that 16K address space, the buffer may be assigned any one of four
2574positions, determined by the offset, switches 7 and 8 of group SW2.
