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.

See the - more general information near the top of this file. - - There is a J2 jumper on two pins. A jumper should be put on them, - since it was already there when I got the card. I don't know what - this jumper is for though. - - There is a two-jumper array for J3. I don't know what it is for, - but there were already two jumpers on it when I got the card.

There are five labelled MS0-MS4 which seem to control the - memory address, and another three labelled IO0-IO2 which seem to - control the base I/O address of the card. - - This was difficult to test by trial and error, and the I/O addresses - are in a weird order. This was tested by setting the DIP switches, - rebooting the computer, and attempting to load ARCETHER at various - addresses (mostly between 0x200 and 0x400). The address that caused - the red transmit LED to blink, is the one that I thought works. - - Also, the address 0x3D0 seem to have a special meaning, since the - ARCETHER packet driver loaded fine, but without the red LED - blinking. I don't know what 0x3D0 is for though.

For example if I set an address of - 0xD000, it will use up addresses 0xD000 to 0xD100. - - The memory switches were tested by booting using QEMM386 stealth, - and using LOADHI to see what address automatically became excluded - from the upper memory regions, and then attempting to load ARCETHER - using these addresses. - - I recommend using an ARCnet memory address of 0xD000, and putting - the EMS page frame at 0xC000 while using QEMM stealth mode. That - way, you get contiguous high memory from 0xD100 almost all the way - the end of the megabyte. - - Memory Switch 0 (MS0) didn't seem to work properly when set to OFF - on my card.
