It should probably be moved out of 7 the kernel sources. Ideas? 8 ----------------------------------------------------------------------------- 9 10 Because so many people (myself included) seem to have obtained ARCnet cards 11 without manuals, this file contains a quick introduction to ARCnet hardware, 12 some cabling tips, and a listing of all jumper settings I can find. Please 13 e-mail apenwarr@worldvisions.ca with any settings for your particular card, 14 or any other information you have! 15 16 17 INTRODUCTION TO ARCNET 18 ---------------------- 19 20 ARCnet is a network type which works in a way similar to popular Ethernet 21 networks but which is also different in some very important ways. 22 23 First 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, 25 there are others as well, but these are less common. The different hardware 26 types, as far as I'm aware, are not compatible and so you cannot wire a 27 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does 28 work with 100 Mbps cards, but I haven't been able to verify this myself, 29 since I only have the 2.5 Mbps variety. It is probably not going to saturate 30 your 100 Mbps card. Stop complaining. :) 31 32 You also cannot connect an ARCnet card to any kind of Ethernet card and 33 expect it to work. 34 35 There are two "types" of ARCnet - STAR topology and BUS topology. This 36 refers to how the cards are meant to be wired together. According to most 37 available documentation, you can only connect STAR cards to STAR cards and 38 BUS cards to BUS cards. That makes sense, right? Well, it's not quite 39 true; see below under "Cabling." 40 41 Once you get past these little stumbling blocks, ARCnet is actually quite a 42 well-designed standard. It uses something called "modified token passing" 43 which makes it completely incompatible with so-called "Token Ring" cards, 44 but which makes transfers much more reliable than Ethernet does. In fact, 45 ARCnet will guarantee that a packet arrives safely at the destination, and 46 even if it can't possibly be delivered properly (ie. because of a cable 47 break, or because the destination computer does not exist) it will at least 48 tell the sender about it. 49 50 Because of the carefully defined action of the "token", it will always make 51 a pass around the "ring" within a maximum length of time. This makes it 52 useful for realtime networks. 53 54 In addition, all known ARCnet cards have an (almost) identical programming 55 interface. This means that with one ARCnet driver you can support any 56 card, whereas with Ethernet each manufacturer uses what is sometimes a 57 completely different programming interface, leading to a lot of different, 58 sometimes very similar, Ethernet drivers. Of course, always using the same 59 programming interface also means that when high-performance hardware 60 facilities like PCI bus mastering DMA appear, it's hard to take advantage of 61 them. Let's not go into that. 62 63 One thing that makes ARCnet cards difficult to program for, however, is the 64 limit on their packet sizes; standard ARCnet can only send packets that are 65 up to 508 bytes in length. This is smaller than the Internet "bare minimum" 66 of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra 67 level of encapsulation is defined by RFC1201, which I call "packet 68 splitting," that allows "virtual packets" to grow as large as 64K each, 69 although they are generally kept down to the Ethernet-style 1500 bytes. 70 71 For more information on the advantages and disadvantages (mostly the 72 advantages) of ARCnet networks, you might try the "ARCnet Trade Association" 73 WWW page: 74 http://www.arcnet.com 75 76 77 CABLING ARCNET NETWORKS 78 ----------------------- 79 80 This section was rewritten by 81 Vojtech Pavlik <vojtech@suse.cz> 82 using 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> 87 and Avery touched it up a bit, at Vojtech's request. 88 89 ARCnet (the classic 2.5 Mbps version) can be connected by two different 90 types 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 92 cabling (Type1, Fiber, C1, C4, C5). 93 94 For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables 95 also work fine, because ARCnet is a very stable network. I personally use 75 96 Ohm TV antenna cable. 97 98 Cards for coax cabling are shipped in two different variants: for BUS and 99 STAR network topologies. They are mostly the same. The only difference 100 lies in the hybrid chip installed. BUS cards use high impedance output, 101 while STAR use low impedance. Low impedance card (STAR) is electrically 102 equal to a high impedance one with a terminator installed. 103 104 Usually, the ARCnet networks are built up from STAR cards and hubs. There 105 are two types of hubs - active and passive. Passive hubs are small boxes 106 with four BNC connectors containing four 47 Ohm resistors: 107 108 | | wires 109 R + junction 110 -R-+-R- R 47 Ohm resistors 111 R 112 | 113 114 The shielding is connected together. Active hubs are much more complicated; 115 they are powered and contain electronics to amplify the signal and send it 116 to other segments of the net. They usually have eight connectors. Active 117 hubs come in two variants - dumb and smart. The dumb variant just 118 amplifies, but the smart one decodes to digital and encodes back all packets 119 coming through. This is much better if you have several hubs in the net, 120 since many dumb active hubs may worsen the signal quality. 121 122 And now to the cabling. What you can connect together: 123 124 1. A card to a card. This is the simplest way of creating a 2-computer 125 network. 126 127 2. 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.) 132 133 3. 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. 137 138 4. An active hub to another. 139 140 5. An active hub to passive hub. 141 142 Remember that you cannot connect two passive hubs together. The power loss 143 implied by such a connection is too high for the net to operate reliably. 144 145 An 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 155 156 The BUS topology is very similar to the one used by Ethernet. The only 157 difference is in cable and terminators: they should be 93 Ohm. Ethernet 158 uses 50 Ohm impedance. You use T connectors to put the computers on a single 159 line of cable, the bus. You have to put terminators at both ends of the 160 cable. 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 168 169 But that is not all! The two types can be connected together. According to 170 the official documentation the only way of connecting them is using an active 171 hub: 172 173 A------T------T------TR 174 | B B B 175 S---H---S 176 | 177 S 178 179 The official docs also state that you can use STAR cards at the ends of 180 BUS network in place of a BUS card and a terminator: 181 182 S------T------T------S 183 B B 184 185 But, according to my own experiments, you can simply hang a BUS type card 186 anywhere in middle of a cable in a STAR topology network. And more - you 187 can use the bus card in place of any star card if you use a terminator. Then 188 you can build very complicated networks fulfilling all your needs! An 189 example: 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 203 204 A basically different cabling scheme is used with Twisted Pair cabling. Each 205 of the TP cards has two RJ (phone-cord style) connectors. The cards are 206 then daisy-chained together using a cable connecting every two neighboring 207 cards. The ends are terminated with RJ 93 Ohm terminators which plug into 208 the empty connectors of cards on the ends of the chain. An example: 209 210 ___________ ___________ 211 _R_|_ _|_|_ _|_R_ 212 | | | | | | 213 |Card | |Card | |Card | 214 |_____| |_____| |_____| 215 216 217 There are also hubs for the TP topology. There is nothing difficult 218 involved in using them; you just connect a TP chain to a hub on any end or 219 even at both. This way you can create almost any network configuration. 220 The maximum of 11 hubs between any two computers on the net applies here as 221 well. 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 232 233 Like any network, ARCnet has a limited cable length. These are the maximum 234 cable lengths between two active ends (an active end being an active hub or 235 a 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 242 243 The maximum length of all cables connected to a passive hub is limited to 65 244 meters for RG-62 cabling; less for others. You can see that using passive 245 hubs in a large network is a bad idea. The maximum length of a single "BUS 246 Trunk" is about 300 meters for RG-62. The maximum distance between the two 247 most distant points of the net is limited to 3000 meters. The maximum length 248 of a TP cable between two cards/hubs is 650 meters. 249 250 251 SETTING THE JUMPERS 252 ------------------- 253 254 All 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. 348 349 Also, on many cards (not mine, though) there are red and green LED's. 350 Vojtech 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) 361 362 363 The following is all the specific information people have sent me about 364 their own particular ARCnet cards. It is officially a mess, and contains 365 huge amounts of duplicated information. I have no time to fix it. If you 366 want to, PLEASE DO! Just send me a 'diff -u' of all your changes. 367 368 The model # is listed right above specifics for that card, so you should be 369 able to use your text viewer's "search" function to find the entry you want. 370 If you don't KNOW what kind of card you have, try looking through the 371 various diagrams to see if you can tell. 372 373 If your model isn't listed and/or has different settings, PLEASE PLEASE 374 tell me. I had to figure mine out without the manual, and it WASN'T FUN! 375 376 Even if your ARCnet model isn't listed, but has the same jumpers as another 377 model that is, please e-mail me to say so. 378 379 Cards Listed in this file (in this order, mostly): 380 381 Manufacturer Model # Bits 382 ------------ ------- ---- 383 SMC PC100 8 384 SMC PC110 8 385 SMC PC120 8 386 SMC PC130 8 387 SMC PC270E 8 388 SMC PC500 16 389 SMC PC500Longboard 16 390 SMC PC550Longboard 16 391 SMC PC600 16 392 SMC PC710 8 393 SMC?

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 746 MEMORY. This means the current Linux-ARCnet driver can't use these cards. 747 I have obtained a PC500Longboard and will be doing some experiments on it in 748 the future, but don't hold your breath.

PDI508Plus cards appear to be mainly 1116 software-configured. 1117 1118 Jumpers: 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: 1134 1135 .-------. 1136 o | o o | 1137 :-------: ------> Accessible end of card with connectors 1138 o | o o | in this direction -------> 1139 `-------' 1140 1141 Carl de Billy <CARL@carainfo.com> explains J3 and J4: 1142 1143 J3 Diagram: 1144 1145 .-------. 1146 o | o o | 1147 :-------: TWIST Technology 1148 o | o o | 1149 `-------' 1150 .-------. 1151 | o o | o 1152 :-------: COAX Technology 1153 | o o | o 1154 `-------' 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 1169 DIP 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.

The first 6 switches set the address, the 7th doesn't have any 2255 function, and the 8th switch is used to select "compatible" or "enhanced". 2256 When I got my two cards, one of them had this switch set to "enhanced". That 2257 card didn't work at all, it wasn't even recognized by the driver. The other 2258 card had this switch set to "compatible" and it behaved absolutely normally. I 2259 guess that the switch on one of the cards, must have been changed accidentally 2260 when the card was taken out of its former host. The question remains 2261 unanswered, what is the purpose of the "enhanced" position? 2262 2263 [Avery's note: "enhanced" probably either disables shared memory (use IO 2264 ports instead) or disables IO ports (use memory addresses instead). This 2265 varies by the type of card involved. I fail to see how either of these 2266 enhance anything. Send me more detailed information about this mode, or 2267 just use "compatible" mode instead.] 2268 2269 2270 ***************************************************************************** 2271 2272 ** Waterloo Microsystems Inc. ?? ** 2273 8-bit card (C) 1985 2274 ------------------- 2275 - from Robert Michael Best <rmb117@cs.usask.ca> 2276 2277 [Avery's note: these don't work with my driver for some reason.
