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@bond.net 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: 2.5Mbps (slower than Ethernet) and 100Mbps (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 100Mbps card to a 2.5Mbps card, and so on. From what I hear, my driver does work with 100Mbps cards, but I haven't been able to verify this myself, since I only have the 2.5Mbps variety. It is probably not going to saturate your 100Mbps 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 busmastering 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.Pavlik@st.mff.cuni.cz> using information from several people, including: Avery Pennraun <apenwarr@bond.net> 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 can not 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.Pavlik@st.mff.cuni.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.Pavlik@st.mff.cuni.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. It is officially a mess, and contains huge amounts of duplicated information. I have no time to fix it. If you want to, PLEASE DO! Just send me a 'diff -u' of all your changes. The model # is listed right above specifics for that card, so you should be able to use your text viewer's "search" function to find the entry you want. If you don't KNOW what kind of card you have, try looking through the various diagrams to see if you can tell. If your model isn't listed and/or has different settings, PLEASE PLEASE tell me. I had to figure mine out without the manual, and it WASN'T FUN! Even if your ARCnet model isn't listed, but has the same jumpers as another model that is, please e-mail me to say so.

Setting the Node ID ------------------- The eight switches in group S2 are used to set the node ID. These switches work in a way similar to the PC100-series cards; see that entry for more information. Setting the I/O Base Address ---------------------------- The first three switches in switch group S1 are used to select one of eight possible I/O Base addresses using the following table Switch | Hex I/O 1 2 3 | Address -------|-------- 0 0 0 | 260 0 0 1 | 290 0 1 0 | 2E0 (Manufacturer's default) 0 1 1 | 2F0 1 0 0 | 300 1 0 1 | 350 1 1 0 | 380 1 1 1 | 3E0 Setting the Base Memory (RAM) buffer Address -------------------------------------------- The memory buffer requires 2K of a 16K block of RAM. The base of this 16K block can be located in any of eight positions. Switches 4-6 of switch group S1 select the Base of the 16K block. Within that 16K address space, the buffer may be assigned any one of four positions, determined by the offset, switches 7 and 8 of group S1.

The default is jumper ROM not installed. Setting the Timeouts and Interrupt ---------------------------------- The jumpers labeled EXT1 and EXT2 are used to determine the timeout parameters. These two jumpers are normally left open. To select a hardware interrupt level set one (only one!) of the jumpers IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2. Configuring the PC130E for Star or Bus Topology ----------------------------------------------- The single jumper labeled STAR is used to configure the PC130E board for star or bus topology. When the jumper is installed, the board may be used in a star network, when it is removed, the board can be used in a bus topology. Diagnostic LEDs --------------- Two diagnostic LEDs are visible on the rear bracket of the board.

The interrupt level is binary coded, so selections from 0 to 15 would be possible, but only the following eight values will be supported: 3, 4, 5, 7, 9, 10, 11, 12. Switch | IRQ 10 9 8 7 | ---------|-------- 0 0 1 1 | 3 0 1 0 0 | 4 0 1 0 1 | 5 0 1 1 1 | 7 1 0 0 1 | 9 (=2) (default) 1 0 1 0 | 10 1 0 1 1 | 11 1 1 0 0 | 12 Setting the Timeouts -------------------- The two jumpers JP2 (1-4) are used to determine the timeout parameters. These two jumpers are normally left open. Refer to the COM9026 Data Sheet for alternate configurations. Configuring the PC500 for Star or Bus Topology ---------------------------------------------- The single jumper labeled JP6 is used to configure the PC500 board for star or bus topology. When the jumper is installed, the board may be used in a star network, when it is removed, the board can be used in a bus topology. Diagnostic LEDs --------------- Two diagnostic LEDs are visible on the rear bracket of the board. The green LED monitors the network activity: the red one shows the board activity: Green | Status Red | Status -------|------------------- ---------|------------------- on | normal activity flash/on | data transfer blink | reconfiguration off | no data transfer; off | defective board or | incorrect memory or | node ID is zero | I/O address ***************************************************************************** ** SMC ** PC710 (8-bit card) ------------------ - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl> Note: this data is gathered by experimenting and looking at info of other cards. However, I'm sure I got 99% of the settings right. The SMC710 card resembles the PC270 card, but is much more basic (i.e. no LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing: _______________________________________ | +---------+ +---------+ |____ | | S2 | | S1 | | | +---------+ +---------+ | | | | +===+ __ | | | R | | | X-tal ###___ | | O | |__| ####__'| | | M | || ### | +===+ | | | | ..

I know it works when connected to a PC110 type ARCnet board. ***************************************************************************** ** Possibly SMC ** LCS-8830(-T) (8 and 16-bit cards) --------------------------------- - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE> - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS only (the JP0 jumper is hardwired), and BNC only. This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC, nowhere else, not even on the few xeroxed sheets from the manual).

PDI508Plus cards appear to be mainly software-configured. Jumpers: There is a jumper array at the bottom of the card, near the edge connector. This array is labelled J1. They control the IRQs and something else. Put only one jumper on the IRQ pins. ETS1, ETS2 are for timing on very long distance networks. 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. It's a six pin grid in a two-by-three fashion. The jumpers were configured as follows: .-------. o | o o | :-------: ------> Accessible end of card with connectors o | o o | in this direction -------> `-------' Carl de Billy <CARL@carainfo.com> explains J3 and J4: J3 Diagram: .-------. o | o o | :-------: TWIST Technology o | o o | `-------' .-------. | o o | o :-------: COAX Technology | o o | o `-------' - If using coax cable in a bus topology the J4 jumper must be removed; place it on one pin. - If using bus topology with twisted pair wiring move the J3 jumpers so they connect the middle pin and the pins closest to the RJ11 Connectors. Also the J4 jumper must be removed; place it on one pin of J4 jumper for storage. - If using star topology with twisted pair wiring move the J3 jumpers so they connect the middle pin and the pins closest to the RJ11 connectors. DIP Switches: The DIP switches accessible on the accessible end of the card while it is installed, is used to set the arcnet address. There are 8 switches. Use an address from 1 to 254. Switch No. 12345678 Arcnet address ----------------------------------------- 00000000 FF (Don't use this!) 00000001 FE 00000010 FD .... 11111101 2 11111110 1 11111111 0 (Don't use this!) There is another array of eight DIP switches at the top of 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. I recommend using an address of 0x300 since Windows may not like addresses below 0x300. IO Switch No. 210 I/O address ------------------------------- 111 0x260 110 0x290 101 0x2E0 100 0x2F0 011 0x300 010 0x350 001 0x380 000 0x3E0 The memory switches set a reserved address space of 0x1000 bytes (0x100 segment units, or 4k). 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. It could be malfunctioning on my card. Experiment with it ON first, and if it doesn't work, set it to OFF. (It may be a modifier for the 0x200 bit?)

LED1 Activity LED BNC Coax connector (STAR arcnet) RAM 2k of SRAM ROM Boot ROM socket UFS Unidentified Flying Sockets Setting the Node ID ------------------- The eight switches in SW2 are used to set the node ID. Each node attached to the network must have an unique node ID which must not be 0. Switch 1 (ID0) serves as the least significant bit (LSB). Setting one of the switches to OFF means "1", ON means "0". The node ID is the sum of the values of all switches set to "1" These values are: Switch | Value -------|------- 1 | 1 2 | 2 3 | 4 4 | 8 5 | 16 6 | 32 7 | 64 8 | 128 Don't set this to 0 or 255; these values are reserved. Setting the I/O Base Address ---------------------------- The switches 1 to 6 of switch block SW1 are used to select one of 32 possible I/O Base addresses using the following tables | Hex Switch | Value -------|------- 1 | 200 2 | 100 3 | 80 4 | 40 5 | 20 6 | 10 The I/O address is sum of all switches set to "1". Remember that the I/O address space bellow 0x200 is RESERVED for mainboard, so switch 1 should be ALWAYS SET TO OFF. Setting the Base Memory (RAM) buffer Address -------------------------------------------- The memory buffer (RAM) requires 2K. The base of this buffer can be located in any of sixteen positions. However, the addresses below A0000 are likely to cause system hang because there's main RAM. Jumpers 7-10 of switch block SW1 select the Memory Base address. Switch | Hex RAM 7 8 9 10 | Address ----------------|--------- OFF OFF OFF OFF | F0000 (conflicts with main BIOS) OFF OFF OFF ON | E0000 OFF OFF ON OFF | D0000 OFF OFF ON ON | C0000 (conflicts with video BIOS) OFF ON OFF OFF | B0000 (conflicts with mono video) OFF ON OFF ON | A0000 (conflicts with graphics) Setting the Interrupt Line -------------------------- Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means shorted, OFF means open. Jumper | IRQ 1 2 3 4 5 | ---------------------------- ON OFF OFF OFF OFF | 7 OFF ON OFF OFF OFF | 5 OFF OFF ON OFF OFF | 4 OFF OFF OFF ON OFF | 3 OFF OFF OFF OFF ON | 2 Unknown jumpers & sockets ------------------------- I know nothing about these. I just guess that J16&J17 are timeout jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't guess the purpose. ***************************************************************************** ** Datapoint? ** LAN-ARC-8, an 8-bit card ------------------------ - from Vojtech Pavlik <Vojtech.Pavlik@st.mff.cuni.cz> This is another SMC 90C65 based arcnet card.

There is a DIP-switch with 8 switches, used to set the shared memory address to be used. The first 6 switches set the address, the 7th doesn't have any function, and the 8th switch is used to select "compatible" or "enhanced". When I got my two cards, one of them had this switch set to "enhanced". That card didn't work at all, it wasn't even recognized by the driver. The other card had this switch set to "compatible" and it behaved absolutely normally. I guess that the switch on one of the cards, must have been changed accidently when the card was taken out of its former host. The question remains unanswered, what is the purpose of the "enhanced" position? [Avery's note: "enhanced" probably either disables shared memory (use IO ports instead) or disables IO ports (use memory addresses instead). This varies by the type of card involved. I fail to see how either of these enhance anything. Send me more detailed information about this mode, or just use "compatible" mode instead.] ***************************************************************************** ** Waterloo Microsystems Inc. ?? ** 8-bit card (C) 1985 ------------------- - from Robert Michael Best <rmb117@cs.usask.ca> [Avery's note: these don't work with my driver for some reason. These cards SEEM to have settings similar to the PDI508Plus, which is software-configured and doesn't work with my driver either. The "Waterloo chip" is a boot PROM, probably designed specifically for the University of Waterloo. If you have any further information about this card, please e-mail me.] The probe has not been able to detect the card on any of the J2 settings, and I tried them again with the "Waterloo" chip removed. _____________________________________________________________________ | \/ \/ ___ __ __ | | C4 C4 |^| | M || ^ ||^| | | -- -- |_| | 5 || || | C3 | | \/ \/ C10 |___|| ||_| | | C4 C4 _ _ | | ?? | | -- -- | \/ || | | | | || | | | | || C1 | | | | || | \/ _____| | | C6 || | C9 | |___ | | || | -- | BNC |___| | | || | >C7| |_____| | | || | | | __ __ |____||_____| 1 2 3 6 | || ^ | >C4| |o|o|o|o|o|o| J2 >C4| | || | |o|o|o|o|o|o| | || C2 | >C4| >C4| | || | >C8| | || | 2 3 4 5 6 7 IRQ >C4| | ||_____| |o|o|o|o|o|o| J3 | |_______ |o|o|o|o|o|o| _______________| | | |_____________________________________________| C1 -- "COM9026 SMC 8638" In a chip socket.

Setting the Node ID ------------------- The eight switches in group SW2 are used to set the node ID. Each node attached to the network must have an unique node ID which must be different from 0. Switch 8 serves as the least significant bit (LSB). The node ID is the sum of the values of all switches set to "1" These values are: Switch | Value -------|------- 8 | 1 7 | 2 6 | 4 5 | 8 4 | 16 3 | 32 2 | 64 1 | 128 Some Examples: Switch | Hex | Decimal 1 2 3 4 5 6 7 8 | Node ID | Node ID ----------------|---------|--------- 0 0 0 0 0 0 0 0 | not allowed 0 0 0 0 0 0 0 1 | 1 | 1 0 0 0 0 0 0 1 0 | 2 | 2 0 0 0 0 0 0 1 1 | 3 | 3 . . . | | 0 1 0 1 0 1 0 1 | 55 | 85 . . . | | 1 0 1 0 1 0 1 0 | AA | 170 . . . | | 1 1 1 1 1 1 0 1 | FD | 253 1 1 1 1 1 1 1 0 | FE | 254 1 1 1 1 1 1 1 1 | FF | 255 Setting the I/O Base Address ---------------------------- The first three switches in switch group SW1 are used to select one of eight possible I/O Base addresses using the following table Switch | Hex I/O 3 2 1 | Address ------------|-------- ON ON ON | 260 ON ON OFF | 290 ON OFF ON | 2E0 (Manufacturer's default) ON OFF OFF | 2F0 OFF ON ON | 300 OFF ON OFF | 350 OFF OFF ON | 380 OFF OFF OFF | 3E0 Setting the Base Memory (RAM) buffer Address -------------------------------------------- The memory buffer requires 2K of a 16K block of RAM. The base of this 16K block can be located in any of eight positions. Switches 6-8 of switch group SW1 select the Base of the 16K block. Within that 16K address space, the buffer may be assigned any one of four positions, determined by the offset, switches 4 and 5 of group SW1.

Setting the jumpers to ON means connecting the upper two pins, off the bottom two - or - in case of IRQ setting, connecting none of them at all. Setting the Node ID ------------------- The eight switches in SW2 are used to set the node ID. Each node attached to the network must have an unique node ID which must not be 0. Switch 1 (ID0) serves as the least significant bit (LSB). Setting one of the switches to Off means "1", On means "0".

The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders. Setting the Interrupt Line -------------------------- Jumpers 1-5 of the jumper block SW3 control the IRQ level. Jumper | IRQ 1 2 3 4 5 | ---------------------------- ON OFF OFF OFF OFF | 2 OFF ON OFF OFF OFF | 3 OFF OFF ON OFF OFF | 4 OFF OFF OFF ON OFF | 5 OFF OFF OFF OFF ON | 7 Setting the Timeout Parameters ------------------------------ The jumpers 6-7 of the jumper block SW3 are used to determine the timeout parameters. These two jumpers are normally left in the OFF position. ***************************************************************************** ** No Name ** (Generic Model 9058) -------------------- - from Andrew J.

What gives?! SW1: Timeouts, Interrupt and ROM --------------------------------- To select a hardware interrupt level set one (only one!) of the dip switches up (on) SW1...(switches 1-5) IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2. The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7) are used to determine the timeout parameters. These two dip switches are normally left off (down). To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM. The default is jumper ROM not installed. Setting the I/O Base Address ---------------------------- The last three switches in switch group SW2 are used to select one of eight possible I/O Base addresses using the following table Switch | Hex I/O 4 5 6 | Address -------|-------- 0 0 0 | 260 0 0 1 | 290 0 1 0 | 2E0 (Manufacturer's default) 0 1 1 | 2F0 1 0 0 | 300 1 0 1 | 350 1 1 0 | 380 1 1 1 | 3E0 Setting the Base Memory Address (RAM & ROM) ------------------------------------------- The memory buffer requires 2K of a 16K block of RAM. The base of this 16K block can be located in any of eight positions. Switches 1-3 of switch group SW2 select the Base of the 16K block. (0 = DOWN, 1 = UP) I could, however, only verify two settings...
