It should probably be moved out of + the kernel sources. Ideas? +----------------------------------------------------------------------------- + +Because so many people (myself included) seem to have obtained ARCnet cards +without manuals, this file contains a quick introduction to ARCnet hardware, +some cabling tips, and a listing of all jumper settings I can find. Please +e-mail apenwarr@worldvisions.ca with any settings for your particular card, +or any other information you have! + + +INTRODUCTION TO ARCNET +---------------------- + +ARCnet is a network type which works in a way similar to popular Ethernet +networks but which is also different in some very important ways. + +First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps +(slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact, +there are others as well, but these are less common. The different hardware +types, as far as I'm aware, are not compatible and so you cannot wire a +100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does +work with 100 Mbps cards, but I haven't been able to verify this myself, +since I only have the 2.5 Mbps variety. It is probably not going to saturate +your 100 Mbps card. Stop complaining. :) + +You also cannot connect an ARCnet card to any kind of Ethernet card and +expect it to work. + +There are two "types" of ARCnet - STAR topology and BUS topology. This +refers to how the cards are meant to be wired together. According to most +available documentation, you can only connect STAR cards to STAR cards and +BUS cards to BUS cards. That makes sense, right? Well, it's not quite +true; see below under "Cabling." + +Once you get past these little stumbling blocks, ARCnet is actually quite a +well-designed standard. It uses something called "modified token passing" +which makes it completely incompatible with so-called "Token Ring" cards, +but which makes transfers much more reliable than Ethernet does. In fact, +ARCnet will guarantee that a packet arrives safely at the destination, and +even if it can't possibly be delivered properly (ie. because of a cable +break, or because the destination computer does not exist) it will at least +tell the sender about it. + +Because of the carefully defined action of the "token", it will always make +a pass around the "ring" within a maximum length of time. This makes it +useful for realtime networks. + +In addition, all known ARCnet cards have an (almost) identical programming +interface. This means that with one ARCnet driver you can support any +card, whereas with Ethernet each manufacturer uses what is sometimes a +completely different programming interface, leading to a lot of different, +sometimes very similar, Ethernet drivers. Of course, always using the same +programming interface also means that when high-performance hardware +facilities like PCI bus mastering DMA appear, it's hard to take advantage of +them. Let's not go into that. + +One thing that makes ARCnet cards difficult to program for, however, is the +limit on their packet sizes; standard ARCnet can only send packets that are +up to 508 bytes in length. This is smaller than the Internet "bare minimum" +of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra +level of encapsulation is defined by RFC1201, which I call "packet +splitting," that allows "virtual packets" to grow as large as 64K each, +although they are generally kept down to the Ethernet-style 1500 bytes. + +For more information on the advantages and disadvantages (mostly the +advantages) of ARCnet networks, you might try the "ARCnet Trade Association" +WWW page: + http://www.arcnet.com + + +CABLING ARCNET NETWORKS +----------------------- + +This section was rewritten by + Vojtech Pavlik <vojtech@suse.cz> +using information from several people, including: + Avery Pennraun <apenwarr@worldvisions.ca> + Stephen A. Wood <saw@hallc1.cebaf.gov> + John Paul Morrison <jmorriso@bogomips.ee.ubc.ca> + Joachim Koenig <jojo@repas.de> +and Avery touched it up a bit, at Vojtech's request. + +ARCnet (the classic 2.5 Mbps version) can be connected by two different +types of cabling: coax and twisted pair. The other ARCnet-type networks +(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of +cabling (Type1, Fiber, C1, C4, C5). + +For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables +also work fine, because ARCnet is a very stable network. I personally use 75 +Ohm TV antenna cable. + +Cards for coax cabling are shipped in two different variants: for BUS and +STAR network topologies. They are mostly the same. The only difference +lies in the hybrid chip installed. BUS cards use high impedance output, +while STAR use low impedance. Low impedance card (STAR) is electrically +equal to a high impedance one with a terminator installed. + +Usually, the ARCnet networks are built up from STAR cards and hubs. There +are two types of hubs - active and passive. Passive hubs are small boxes +with four BNC connectors containing four 47 Ohm resistors: + + | | wires + R + junction +-R-+-R- R 47 Ohm resistors + R + | + +The shielding is connected together. Active hubs are much more complicated; +they are powered and contain electronics to amplify the signal and send it +to other segments of the net. They usually have eight connectors. Active +hubs come in two variants - dumb and smart. The dumb variant just +amplifies, but the smart one decodes to digital and encodes back all packets +coming through. This is much better if you have several hubs in the net, +since many dumb active hubs may worsen the signal quality. + +And now to the cabling. What you can connect together: + +1. A card to a card. This is the simplest way of creating a 2-computer + network. + +2. A card to a passive hub. Remember that all unused connectors on the hub + must be properly terminated with 93 Ohm (or something else if you don't + have the right ones) terminators. + (Avery's note: oops, I didn't know that. Mine (TV cable) works + anyway, though.) + +3. A card to an active hub. Here is no need to terminate the unused + connectors except some kind of aesthetic feeling. But, there may not be + more than eleven active hubs between any two computers. That of course + doesn't limit the number of active hubs on the network. + +4. An active hub to another. + +5. An active hub to passive hub. + +Remember that you cannot connect two passive hubs together. The power loss +implied by such a connection is too high for the net to operate reliably. + +An example of a typical ARCnet network: + + R S - STAR type card + S------H--------A-------S R - Terminator + | | H - Hub + | | A - Active hub + | S----H----S + S | + | + S + +The BUS topology is very similar to the one used by Ethernet. The only +difference is in cable and terminators: they should be 93 Ohm. Ethernet +uses 50 Ohm impedance. You use T connectors to put the computers on a single +line of cable, the bus. You have to put terminators at both ends of the +cable. A typical BUS ARCnet network looks like: + + RT----T------T------T------T------TR + B B B B B B + + B - BUS type card + R - Terminator + T - T connector + +But that is not all! The two types can be connected together. According to +the official documentation the only way of connecting them is using an active +hub: + + A------T------T------TR + | B B B + S---H---S + | + S + +The official docs also state that you can use STAR cards at the ends of +BUS network in place of a BUS card and a terminator: + + S------T------T------S + B B + +But, according to my own experiments, you can simply hang a BUS type card +anywhere in middle of a cable in a STAR topology network. And more - you +can use the bus card in place of any star card if you use a terminator. Then +you can build very complicated networks fulfilling all your needs! An +example: + + S + | + RT------T-------T------H------S + B B B | + | R + S------A------T-------T-------A-------H------TR + | B B | | B + | S BT | + | | | S----A-----S + S------H---A----S | | + | | S------T----H---S | + S S B R S + +A basically different cabling scheme is used with Twisted Pair cabling. Each +of the TP cards has two RJ (phone-cord style) connectors. The cards are +then daisy-chained together using a cable connecting every two neighboring +cards. The ends are terminated with RJ 93 Ohm terminators which plug into +the empty connectors of cards on the ends of the chain. An example: + + ___________ ___________ + _R_|_ _|_|_ _|_R_ + | | | | | | + |Card | |Card | |Card | + |_____| |_____| |_____| + + +There are also hubs for the TP topology. There is nothing difficult +involved in using them; you just connect a TP chain to a hub on any end or +even at both. This way you can create almost any network configuration. +The maximum of 11 hubs between any two computers on the net applies here as +well. An example: + + RP-------P--------P--------H-----P------P-----PR + | + RP-----H--------P--------H-----P------PR + | | + PR PR + + R - RJ Terminator + P - TP Card + H - TP Hub + +Like any network, ARCnet has a limited cable length. These are the maximum +cable lengths between two active ends (an active end being an active hub or +a STAR card). + + RG-62 93 Ohm up to 650 m + RG-59/U 75 Ohm up to 457 m + RG-11/U 75 Ohm up to 533 m + IBM Type 1 150 Ohm up to 200 m + IBM Type 3 100 Ohm up to 100 m + +The maximum length of all cables connected to a passive hub is limited to 65 +meters for RG-62 cabling; less for others. You can see that using passive +hubs in a large network is a bad idea. The maximum length of a single "BUS +Trunk" is about 300 meters for RG-62. The maximum distance between the two +most distant points of the net is limited to 3000 meters. The maximum length +of a TP cable between two cards/hubs is 650 meters. + + +SETTING THE JUMPERS +------------------- + +All ARCnet cards should have a total of four or five different settings: + + - the I/O address: this is the "port" your ARCnet card is on. Probed + values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If + your card has additional ones, which is possible, please tell me.) This + should not be the same as any other device on your system. According to + a doc I got from Novell, MS Windows prefers values of 0x300 or more, + eating net connections on my system (at least) otherwise. My guess is + this may be because, if your card is at 0x2E0, probing for a serial port + at 0x2E8 will reset the card and probably mess things up royally. + - Avery's favourite: 0x300. + + - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7. + on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15. + + Make sure this is different from any other card on your system. Note + that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can + "cat /proc/interrupts" for a somewhat complete list of which ones are in + use at any given time. Here is a list of common usages from Vojtech + Pavlik <vojtech@suse.cz>: + ("Not on bus" means there is no way for a card to generate this + interrupt) + IRQ 0 - Timer 0 (Not on bus) + IRQ 1 - Keyboard (Not on bus) + IRQ 2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU) + IRQ 3 - COM2 + IRQ 4 - COM1 + IRQ 5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP) + IRQ 6 - Floppy disk controller + IRQ 7 - FREE (LPT1 if you don't use the polling driver; PLIP) + IRQ 8 - Realtime Clock Interrupt (Not on bus) + IRQ 9 - FREE (VGA vertical sync interrupt if enabled) + IRQ 10 - FREE + IRQ 11 - FREE + IRQ 12 - FREE + IRQ 13 - Numeric Coprocessor (Not on bus) + IRQ 14 - Fixed Disk Controller + IRQ 15 - FREE (Fixed Disk Controller 2 if you have it) + + Note: IRQ 9 is used on some video cards for the "vertical retrace" + interrupt. This interrupt would have been handy for things like + video games, as it occurs exactly once per screen refresh, but + unfortunately IBM cancelled this feature starting with the original + VGA and thus many VGA/SVGA cards do not support it. For this + reason, no modern software uses this interrupt and it can almost + always be safely disabled, if your video card supports it at all. + + If your card for some reason CANNOT disable this IRQ (usually there + is a jumper), one solution would be to clip the printed circuit + contact on the board: it's the fourth contact from the left on the + back side. I take no responsibility if you try this. + + - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though. + + - the memory address: Unlike most cards, ARCnets use "shared memory" for + copying buffers around. Make SURE it doesn't conflict with any other + used memory in your system! + A0000 - VGA graphics memory (ok if you don't have VGA) + B0000 - Monochrome text mode + C0000 \ One of these is your VGA BIOS - usually C0000. + E0000 / + F0000 - System BIOS + + Anything less than 0xA0000 is, well, a BAD idea since it isn't above + 640k. + - Avery's favourite: 0xD0000 + + - the station address: Every ARCnet card has its own "unique" network + address from 0 to 255. Unlike Ethernet, you can set this address + yourself with a jumper or switch (or on some cards, with special + software). Since it's only 8 bits, you can only have 254 ARCnet cards + on a network. DON'T use 0 or 255, since these are reserved (although + neat stuff will probably happen if you DO use them). By the way, if you + haven't already guessed, don't set this the same as any other ARCnet on + your network! + - Avery's favourite: 3 and 4. Not that it matters. + + - There may be ETS1 and ETS2 settings. These may or may not make a + difference on your card (many manuals call them "reserved"), but are + used to change the delays used when powering up a computer on the + network. This is only necessary when wiring VERY long range ARCnet + networks, on the order of 4km or so; in any case, the only real + requirement here is that all cards on the network with ETS1 and ETS2 + jumpers have them in the same position. Chris Hindy <chrish@io.org> + sent in a chart with actual values for this: + ET1 ET2 Response Time Reconfiguration Time + --- --- ------------- -------------------- + open open 74.7us 840us + open closed 283.4us 1680us + closed open 561.8us 1680us + closed closed 1118.6us 1680us + + Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your + network. + +Also, on many cards (not mine, though) there are red and green LED's. +Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean: + GREEN RED Status + ----- --- ------ + OFF OFF Power off + OFF Short flashes Cabling problems (broken cable or not + terminated) + OFF (short) ON Card init + ON ON Normal state - everything OK, nothing + happens + ON Long flashes Data transfer + ON OFF Never happens (maybe when wrong ID) + + +The following is all the specific information people have sent me about +their own particular ARCnet cards.
