1) This file is a supplement to arcnet.txt. Please read that for general
driver configuration help.

2) This file is no longer Linux-specific. 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"

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.
Fix "can not" in Documentation and Kconfig Randy brought it to my attention that in proper english "can not" should always be written "cannot". I donot see any reason to argue, even if I mightnot understand why this rule exists. This patch fixes "can not" in several Documentation files as well as three Kconfigs.

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. 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.

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 labeled with RX,PDN,TXI
and another with ALE,LA17,LA18,LA19 these are undocumented..

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

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.

*) To enable the 8K Boot PROM install the jumper ROM.
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 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

- from Juergen Seifert <seifert@htwm.de>
STANDARD MICROSYSTEMS CORPORATION (SMC) ARCNET-PC500/PC550 Long Board
=====================================================================
Note: There is another Version of the PC500 called Short Version, which
is different in hard- and software! The most important differences
are:
- The long board has no Shared memory.
- On the long board the selection of the interrupt is done by binary
coded switch, on the short board directly by jumper.
[Avery's note: pay special attention to that: the long board HAS NO SHARED
MEMORY. This means the current Linux-ARCnet driver can't use these cards.
I have obtained a PC500Longboard and will be doing some experiments on it in
the future, but don't hold your breath. Thanks again to Juergen Seifert for
his advice about this!]

Setting the Node ID
-------------------
The eight switches in group SW3 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 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
-------|-------

Setting the I/O Base Address
----------------------------
The first six switches in switch group SW1 are used to select one
of 32 possible I/O Base addresses using the following table
Switch | Hex I/O
6 5 4 3 2 1 | Address
-------------|--------

Setting the Interrupt
---------------------
Switches seven through ten of switch group SW1 are used to select the
interrupt level. 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

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:
_______________________________________

|||||||||||||||||||||
The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
S1 and S2 perform the same function as on the PC270, only their numbers
are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
I know it works when connected to a PC110 type ARCnet board.

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).

PDI507 (8-bit card)
--------------------
- from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
- Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
are mostly the same as this. 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:

- 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?)
MS Switch No.

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 + 8K or memory base + 0x2000.
Switches 1-5 of switch 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 (Manufacturer'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 install the jumper JP1
Note: Since the switches 1 and 2 are always set to ON it may be possible
that they can be used to add an offset of 2K, 4K or 6K to the base
address, but this feature is not documented in the manual and I
haven't tested it yet.
Setting the Interrupt Line
--------------------------
To select a hardware interrupt level install one (only one!) of the jumpers
JP2, JP3, JP4, JP5, JP6. JP2 is the default.

Setting one of the switches to Off means "1", On means "0".
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 different from 0.
Switch 1 (ID0) 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 | 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:

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 six switches in switch block SW1 are used to select the I/O Base
address using the following table:
Switch | Hex I/O
1 2 3 4 5 6 | Address
------------------------|--------
OFF ON ON OFF OFF ON | 260
OFF ON OFF ON ON OFF | 290
OFF ON OFF OFF OFF ON | 2E0 (Manufacturer's default)
OFF ON OFF OFF OFF OFF | 2F0
OFF OFF ON ON ON ON | 300
OFF OFF ON OFF ON OFF | 350
OFF OFF OFF ON ON ON | 380
OFF OFF OFF OFF OFF ON | 3E0
Note: Other IO-Base addresses seem to be selectable, but only the above
combinations are documented.
Setting the Base Memory (RAM) buffer Address
--------------------------------------------
The switches 7-10 of switch block SW1 are used to select the Memory
Base address of the RAM (2K) and the PROM.
Switch | Hex RAM | Hex ROM
7 8 9 10 | Address | Address
----------------|---------|-----------
OFF OFF ON ON | C0000 | C8000
OFF OFF ON OFF | D0000 | D8000 (Default)
OFF OFF OFF ON | E0000 | E8000
Note: Other MEM-Base addresses seem to be selectable, but only the above
combinations are documented.
Setting the Interrupt Line
--------------------------
To select a hardware interrupt level install one (only one!) of the jumpers
JP3 through JP13 using the following table:
Jumper | IRQ
-------|-----------------
3 | 14
4 | 15
5 | 12
6 | 11
7 | 10
8 | 3
9 | 4
10 | 5
11 | 6
12 | 7
13 | 2 (=9) Default!
Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
Controller
- Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
Hard Disk, it may conflict with their controllers
Setting the Timeout Parameters
------------------------------
The jumpers labeled JP1 and JP2 are used to determine the timeout
parameters. These two jumpers are normally left open.

It seems that the bits are considered in reverse order. Also, you must
observe that some of those addresses are unusual and I didn't probe them; I
used a memory dump in DOS to identify them. For the 00000 configuration and
some others that I didn't write here the card seems to conflict with the
video card (an S3 GENDAC). I leave the full decoding of those addresses to
you.

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.

. . . . .
. . . . .
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 accidentally
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.]

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.

NONAME 8-BIT ARCNET
===================
I have named this ARCnet card "NONAME", since there is no name of any
manufacturer on the Installation manual nor on the shipping box. The only
hint to the existence of a manufacturer at all is written in copper,
it is "Made in Taiwan"

Setting the Node ID
-------------------
The eight switches in group SW1 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

Setting the I/O Base Address
----------------------------
The first 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
1 2 3 | 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 4-6 of switch group SW2 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 SW2.

*) To enable the 8K Boot PROM install the jumper ROM.
The default is jumper ROM not installed.
Setting Interrupt Request Lines (IRQ)
-------------------------------------
To select a hardware interrupt level set one (only one!) of the jumpers
IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
Setting the Timeouts
--------------------
The two jumpers labeled ET1 and ET2 are used to determine the timeout
parameters (response and reconfiguration time). Every node in a network
must be set to the same timeout values.
ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
--------|--------------------|--------------------------
Off Off | 78 | 840 (Default)
Off On | 285 | 1680
On Off | 563 | 1680
On On | 1130 | 1680
On means jumper installed, Off means jumper not installed
NONAME 16-BIT ARCNET
====================
The manual of my 8-Bit NONAME ARCnet Card contains another description
of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
because there are missing two pages in the manual booklet. (The table
of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
the booklet there is a different way of counting ... 2-9, 2-10, A-1,
(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
Also the picture of the board layout is not as good as the picture of
8-Bit card, because there isn't any letter like "SW1" written to the
picture.
Should somebody have such a board, please feel free to complete this
description or to send a mail to me!

Setting one of the switches to Off means "1", On means "0".
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:

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 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 | Label | Value
-------|-------|-------
1 | ID0 | 1
2 | ID1 | 2
3 | ID2 | 4
4 | ID3 | 8

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 following table
Switch | Hex I/O

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 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 adders.
Setting the Interrupt Line
--------------------------
Jumpers 1-5 of the jumper block SW3 control the IRQ level.
Jumper | IRQ

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.

---------------------------------
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

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...
Switch| Hex RAM | Hex ROM
1 2 3 | Address | Address
------|---------|-----------
0 0 0 | E0000 | E2000
0 0 1 | D0000 | D2000 (Manufacturer's default)
0 1 0 | ????? | ?????
0 1 1 | ????? | ?????
1 0 0 | ????? | ?????
1 0 1 | ????? | ?????
1 1 0 | ????? | ?????
1 1 1 | ????? | ?????
Setting the Node ID
-------------------
The eight switches in group SW3 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 1 serves as the least significant bit (LSB).
switches in the DOWN position are OFF (0) and in the UP position are ON (1)
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 |
. . . | | + Don't use 0 or 255!
1 0 1 0 1 0 1 0 | AA | 170 |
