Please 13e-mail apenwarr@worldvisions.ca with any settings for your particular card, 14or any other information you have! 15 16 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 71For more information on the advantages and disadvantages (mostly the 72advantages) of ARCnet networks, you might try the "ARCnet Trade Association" 73WWW page: 74 http://www.arcnet.com 75 76 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.

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. 378 379Cards 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 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.

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: 1134 1135 .-------. 1136 o | o o | 1137 :-------: ------> Accessible end of card with connectors 1138 o | o o | in this direction -------> 1139 `-------' 1140 1141Carl 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 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.

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.
