----------------------------------------------------------------------------- This file is a supplement to README.arcnet. Please read that for general driver configuration help. ----------------------------------------------------------------------------- Because so many people (myself included) seem to have obtained ARCnet cards without manuals, this will be a quick listing of all jumper settings I can find. Please e-mail apenwarr@foxnet.net with any settings for your particular card. Even if your ARCnet model isn't listed, but has the same jumpers, please e-mail me to say so. If your model isn't listed, and has different settings, PLEASE PLEASE tell me. I had to figure mine out without the manual, and it WASN'T FUN!

The model # is listed right above specifics for that card. Don't forget to read "quick briefing" first, since it applies to all ARCnets. Unclassified Stuff ------------------ - Please send any other information you can find. - And some unknowns (other info is welcome!): From: root@ultraworld.xs4all.nl (Timo Hilbrink) To: apenwarr@foxnet.net (Avery Pennarun) Date: Wed, 26 Oct 1994 02:10:32 +0000 (GMT) Reply-To: timoh@xs4all.nl [...parts deleted...] About the jumpers: On my PC130 there is one more jumper, located near the cable-connector and it's for changing to star or bus topology; closed: star - open: bus On the PC500 are some more jumper-pins, one block labled with RX,PDN,TXI and another with ALE,LA17,LA18,LA19 these are undocumented.. [...more parts deleted...] --- CUT --- Quick Briefing: --------------- All ARCnet cards should have a total of four different settings: - the I/O address: this is the "port" your ARCnet card is on. Probed values, as of v0.14, 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 netconnections on my system otherwise. - 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. - Avery's favourite: IRQ2. - 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. 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. ** Standard Microsystems Corp (SMC) ** PC100, PC110, PC120, PC130 (8-bit cards) PC500, PC600 (16-bit cards) --------------------------------- - mainly from Avery Pennarun <apenwarr@foxnet.net>. Values depicted are from Avery's setup. - special thanks to Timo Hilbrink <timoh@xs4all.nl> for noting that PC120, 130, 500, and 600 all have the same switches as Avery's PC100. PC500/600 have several extra, undocumented pins though. (?) - PC110 settings were verified by Stephen A. Wood <saw@cebaf.gov> - On the other hand, John Edward Bauer <jbauer@badlands.NoDak.edu> said the PC110 settings are all wrong. In his case, you need to switch all the 1's with 0's. If you're having problems, try that. - Also, the JP- and S-numbers probably don't match your card exactly. Try to find jumpers/switches with the same number of settings - it's probably more reliable.

Since this board is designed both for point-to-point connection in star networks and for connection to bus networks, it is downwardly compatible with all the other standard boards designed for coax networks (that is, the PC120, PC110 and PC100 star topology boards and the PC220, PC210 and PC200 bus topology boards). The PC270E is an enhanced version of the PC260 board, is equipped with two modular RJ11-type jacks for connection to twisted pair wiring. It can be used in a star or a daisy-chained network. 8 7 6 5 4 3 2 1 ________________________________________________________________ | | S1 | | | |_________________| | | Offs|Base |I/O Addr | | RAM Addr | ___| | ___ ___ CR3 |___| | | \/ | CR4 |___| | | PROM | ___| | | | N | | 8 | | SOCKET | o | | 7 | |________| d | | 6 | ___________________ e | | 5 | | | A | S | 4 | |oo| EXT2 | | d | 2 | 3 | |oo| EXT1 | SMC | d | | 2 | |oo| ROM | 90C63 | r |___| 1 | |oo| IRQ7 | | |o| _____| | |oo| IRQ5 | | |o| | J1 | | |oo| IRQ4 | | STAR |_____| | |oo| IRQ3 | | | J2 | | |oo| IRQ2 |___________________| |_____| |___ ______________| | | |_____________________________________________| Legend: SMC 90C63 ARCNET Controller / Transceiver /Logic S1 1-3: I/O Base Address Select 4-6: Memory Base Address Select 7-8: RAM Offset Select S2 1-8: Node ID Select EXT Extended Timeout Select ROM ROM Enable Select STAR Selected - Star Topology (PC130E only) Deselected - Bus Topology (PC130E only) CR3/CR4 Diagnostic LEDs J1 BNC RG62/U Connector (PC130E only) J1 6-position Telephone Jack (PC270E only) J2 6-position Telephone Jack (PC270E only) Setting one of the switches to Off/Open means "1", On/Closed means "0". Setting the Node ID ------------------- The eight switches in group S2 are used to set the node ID. Each node attached to the network must have an unique node ID which must be diffrent from 0. Switch 1 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 -------|------- 1 | 1 2 | 2 3 | 4 4 | 8 5 | 16 6 | 32 7 | 64 8 | 128 Some Examples: Switch | Hex | Decimal 8 7 6 5 4 3 2 1 | 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 S1 are used to select one of eight possible I/O Base addresses using the followig table Switch | Hex I/O 1 2 3 | Address -------|-------- 0 0 0 | 260 0 0 1 | 290 0 1 0 | 2E0 (Manufactor'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. Refer to the COM9026 Data Sheet for alternate configurations. To select a hardware interrupt level set one (only one!) of the jumpers IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufactor'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.

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. IRQ2 - Use IRQ 2 (same as IRQ 9 as far as software is concerned) IRQ3 - Use IRQ 3 (used by COM2 or COM4 serial port if either exists) IRQ4 - Use IRQ 4 (used by COM1 or COM3 serial port if either exists) IRQ5 - Use IRQ 5 (used by LPT2 parallel port if one exists) IRQ6 - Use IRQ 6 (used by Floppy Disk Controller if one exists) IRQ7 - Use IRQ 7 (used by LPT1 parallel port if one exists) [Avery's note: This "unknown" set of two jumpers appears to be on all ARCnet cards by SMC as well. Putting jumpers on them seems to affect the status register, but only for the two "reserved" bits, ETS1 and ETS2. Any further information is welcome.] ET1 - What is this? (Not tested, no jumper put on it) ET2 - What is this? (Not tested, no jumper put on it) 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 -------> `-------' There is also a J4 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. DIP Switches: The dipswitches 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 dipswitch array of 8 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?)

This description was written by Vojtech Pavlik (vpav4328@diana.troja.mff.cuni.cz) using parts of the ARCNET-jumpers README file from Linux kernel 1.2.2. ____________________________________________________________ | 1 2 3 4 5 6 7 8 | | |o|o| JP1 o|o|o|o|o|o|o|o| ON | | + o|o|o|o|o|o|o|o| ___| | _____________ o|o|o|o|o|o|o|o| OFF _____ | | ID7 | | | SW1 | | | | ID6 | > RAM (2k) | ____________________ | H | | S | ID5 | |_____________| | || y | | W | ID4 | | || b | | 2 | ID3 | | || r | | | ID2 | | || i | | | ID1 | | 90C65 || d | |___| ID0 | SW3 | || | | | |o|o|o|o|o|o|o|o| ON | || I | | | |o|o|o|o|o|o|o|o| | || C | | | |o|o|o|o|o|o|o|o| OFF |____________________|| | _____| | 1 2 3 4 5 6 7 8 | | | |___ | ______________ | | | BNC |___| | | | |_____| |_____| | > EPROM SOCKET | | | |______________| | | ______________| | | |_____________________________________________| Legend: 90C65 ARCNET Chip SW1 1-5: Base Memory Address Select 6-8: Base I/O Address Select SW2 1-8: Node ID Select (ID0-ID7) SW3 1-5: IRQ Select 6-7: Extra Timeout 8 : Rom Enable JP1 Led connector BNC Coax connector Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not switches. 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 be diffrent from 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 | Label | Value -------|-------|------- 1 | ID0 | 1 2 | ID1 | 2 3 | ID2 | 4 4 | ID3 | 8 5 | ID4 | 16 6 | ID5 | 32 7 | ID6 | 64 8 | ID7 | 128 Some Examples: Switch | Hex | Decimal 8 7 6 5 4 3 2 1 | 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 last three switches in switch block SW1 are used to select one of eight possible I/O Base addresses using the followig table Switch | Hex I/O 6 7 8 | Address ------------|-------- ON ON ON | 260 OFF ON ON | 290 ON OFF ON | 2E0 (Manufactor's default) OFF OFF ON | 2F0 ON ON OFF | 300 OFF ON OFF | 350 ON OFF OFF | 380 OFF OFF OFF | 3E0 Setting the Base Memory (RAM) buffer Address -------------------------------------------- The memory buffer (RAM) requires 2K. The base of this buffer can be located in any of eight positions. The address of the Boot Prom is memory base + 0x2000. Jumpers 3-5 of jumper block SW1 select the Memory Base address. Switch | Hex RAM | Hex ROM 1 2 3 4 5 | Address | Address *) --------------------|---------|----------- ON ON ON ON ON | C0000 | C2000 ON ON OFF ON ON | C4000 | C6000 ON ON ON OFF ON | CC000 | CE000 ON ON OFF OFF ON | D0000 | D2000 (Manufactor's default) ON ON ON ON OFF | D4000 | D6000 ON ON OFF ON OFF | D8000 | DA000 ON ON ON OFF OFF | DC000 | DE000 ON ON OFF OFF OFF | E0000 | E2000 *) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON. The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM addres. Setting the Interrupt Line -------------------------- Jumpers 1-5 of the jumper block SW3 controll 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. ***************************************************************************** ** Tiara ** (model unknown) ------------------------- - from Christoph Lameter <clameter@netcom.com> Here is information about my card as far as I could figure it out: ----------------------------------------------- tiara Tiara LanCard of Tiara Computer Systems. +----------------------------------------------+ ! !
