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 37expect it to work. 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" 77WWW page: 78 79 http://www.arcnet.com 80 81 82Cabling ARCnet Networks 83======================= 84 85This section was rewritten by 86 87 Vojtech Pavlik <vojtech@suse.cz> 88 89using information from several people, including: 90 91 - Avery Pennraun <apenwarr@worldvisions.ca> 92 - Stephen A. Wood <saw@hallc1.cebaf.gov> 93 - John Paul Morrison <jmorriso@bogomips.ee.ubc.ca> 94 - Joachim Koenig <jojo@repas.de> 95 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 115with four BNC connectors containing four 47 Ohm resistors:: 116 117 | | wires 118 R + junction 119 -R-+-R- R 47 Ohm resistors 120 R 121 | 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. 139 140 (Avery's note: oops, I didn't know that. Mine (TV cable) works 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. 147 1484. An active hub to another. 149 1505. An active hub to passive hub. 151 152Remember that you cannot connect two passive hubs together. The power loss 153implied by such a connection is too high for the net to operate reliably. 154 155An example of a typical ARCnet network:: 156 157 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 165 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 170cable. A typical BUS ARCnet network looks like:: 171 172 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 181hub:: 182 183 A------T------T------TR 184 | B B B 185 S---H---S 186 | 187 S 188 189The official docs also state that you can use STAR cards at the ends of 190BUS network in place of a BUS card and a terminator:: 191 192 S------T------T------S 193 B B 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 199example:: 200 201 S 202 | 203 RT------T-------T------H------S 204 B B B | 205 | R 206 S------A------T-------T-------A-------H------TR 207 | B B | | B 208 | S BT | 209 | | | S----A-----S 210 S------H---A----S | | 211 | | S------T----H---S | 212 S S B R S 213 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 218the empty connectors of cards on the ends of the chain. An example:: 219 220 ___________ ___________ 221 _R_|_ _|_|_ _|_R_ 222 | | | | | | 223 |Card | |Card | |Card | 224 |_____| |_____| |_____| 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 229even at both. This way you can create almost any network configuration. 230The maximum of 11 hubs between any two computers on the net applies here as 231well. An example:: 232 233 RP-------P--------P--------H-----P------P-----PR 234 | 235 RP-----H--------P--------H-----P------PR 236 | | 237 PR PR 238 239 R - RJ Terminator 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). 246 247 ========== ======= =========== 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 ========== ======= =========== 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. 261 262 263Setting the Jumpers 264=================== 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. 276 277 - Avery's favourite: 0x300. 278 279 - 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. 281 282 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>: 287 288 ("Not on bus" means there is no way for a card to generate this 289 interrupt) 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. 320 321 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! 331 332 :: 333 334 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 339 340 Anything less than 0xA0000 is, well, a BAD idea since it isn't above 341 640k. 342 343 - 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! 353 354 - 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.

The most important differences 767 are: 768 769 - 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. 772 773[Avery's note: pay special attention to that: the long board HAS NO SHARED 774MEMORY. This means the current Linux-ARCnet driver can't use these cards. 775I have obtained a PC500Longboard and will be doing some experiments on it in 776the future, but don't hold your breath.

PDI508Plus cards appear to be mainly 1154 software-configured. 1155 1156Jumpers: 1157 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. 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, 1166 since it was already there when I got the card. I don't know what 1167 this jumper is for though. 1168 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:: 1173 1174 .-------. 1175 o | o o | 1176 :-------: ------> Accessible end of card with connectors 1177 o | o o | in this direction -------> 1178 `-------' 1179 1180Carl de Billy <CARL@carainfo.com> explains J3 and J4: 1181 1182 J3 Diagram:: 1183 1184 .-------. 1185 o | o o | 1186 :-------: TWIST Technology 1187 o | o o | 1188 `-------' 1189 .-------. 1190 | o o | o 1191 :-------: COAX Technology 1192 | o o | o 1193 `-------' 1194 1195 - If using coax cable in a bus topology the J4 jumper must be removed; 1196 place it on one pin. 1197 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. 1202 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. 1206 1207 1208DIP Switches: 1209 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 1213 1214 ========== ========================= 1215 Switch No. ARCnet address 1216 12345678 1217 ========== ========================= 1218 00000000 FF (Don't use this!) 1219 00000001 FE 1220 00000010 FD 1221 ... 1222 11111101 2 1223 11111110 1 1224 11111111 0 (Don't use this!) 1225 ========== ========================= 1226 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. 1231 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. 1237 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. 1243 1244 ============= =========== 1245 IO Switch No. I/O address 1246 210 1247 ============= =========== 1248 111 0x260 1249 110 0x290 1250 101 0x2E0 1251 100 0x2F0 1252 011 0x300 1253 010 0x350 1254 001 0x380 1255 000 0x3E0 1256 ============= =========== 1257 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. 1261 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. 1266 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. 1271 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?) 1276 1277 ============= ============================================ 1278 MS Switch No. 1279 43210 Memory address 1280 ============= ============================================ 1281 00001 0xE100 (guessed - was not detected by QEMM) 1282 00011 0xE000 (guessed - was not detected by QEMM) 1283 00101 0xDD00 1284 00111 0xDC00 1285 01001 0xD900 1286 01011 0xD800 1287 01101 0xD500 1288 01111 0xD400 1289 10001 0xD100 1290 10011 0xD000 1291 10101 0xCD00 1292 10111 0xCC00 1293 11001 0xC900 (guessed - crashes tested system) 1294 11011 0xC800 (guessed - crashes tested system) 1295 11101 0xC500 (guessed - crashes tested system) 1296 11111 0xC400 (guessed - crashes tested system) 1297 ============= ============================================ 1298 1299CNet Technology Inc.

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.] 2338 2339Waterloo Microsystems Inc. ?? 2340============================= 2341 23428-bit card (C) 1985 2343------------------- 2344 - from Robert Michael Best <rmb117@cs.usask.ca> 2345 2346[Avery's note: these don't work with my driver for some reason.
