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 |

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. |
|
|
|

|
advantages) of ARCnet networks, you might try the "ARCnet Trade Association" |

Cabling ARCnet Networks |
|
======================= |
|
|
|
This section was rewritten by |
|
|
|
Vojtech Pavlik <[email protected]> |
|
|
|
using information from several people, including: |
|
|
|
- Avery Pennraun <[email protected]> |
|
- Stephen A. Wood <[email protected]> |
|
- John Paul Morrison <[email protected]> |
|
- Joachim Koenig <[email protected]> |
|
|
|
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 | |
|

|
|
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 <[email protected]>: |
|
|
|
("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 <[email protected]> |
|
sent in a chart with actual values for this: |
|
|
|
======= ======= =============== ==================== |
|
ET1 ET2 Response Time Reconfiguration Time |
|
======= ======= =============== ==================== |
|
open open 74.7us 840us |
|

|
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 <[email protected]> tells me this is what they mean: |

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.. |

The PC130E is an enhanced version of the PC130 board, is equipped with a |
|
standard BNC female connector for connection to RG-62/U coax cable. |
|
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. |

|
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 |
|
-------|-------- |
|

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. |

*) 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 |

PC500/PC550 Longboard (16-bit cards) |
|
------------------------------------ |
|
|
|
- from Juergen Seifert <[email protected]> |
|
|
|
|
|
.. 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 |
|
-------|------- |
|
1 | 1 |

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 |

|
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 |
|
|
|
|
|
PC710 (8-bit card) |
|
------------------ |
|
|
|
- from J.S. van Oosten <[email protected]> |
|
|
|
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 <[email protected]> |
|
- Marek Michalkiewicz <[email protected]> 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 <[email protected]> (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:: |
|
|
|

- 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 |
|
|
|

|
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. |
|
|

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?) |

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: |

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 |
|
6 7 8 | Address |
|
------------|-------- |
|

|
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 + 8K or memory base + 0x2000. |
|
Switches 1-5 of switch block SW1 select the Memory Base address. |
|
|
|
:: |
|
|

|
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 the Internal Terminator on CN120AB/TP/SBT |
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
The jumper JP12 is used to enable the internal terminator:: |
|
|
|
----- |
|
0 | 0 | |
|

Setting the Timeout Parameters |
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
The jumpers labeled EXT1 and EXT2 are used to determine the timeout |
|
parameters. These two jumpers are normally left open. |

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 |
|

|
|
|
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. |

|
|
- from Vojtech Pavlik <[email protected]> using portions of the existing |
|
arcnet-hardware file. |
|

This is a 90C26 based card. Its configuration seems similar to the SMC |
|
PC100, but has some additional jumpers I don't know the meaning of. |

|
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. |
|
|
|

This is another SMC 90C65-based ARCnet card. I couldn't identify the |

|
|
Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means |
|
shorted, OFF means open:: |

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.] |

|
- from Robert Michael Best <[email protected]> |
|
|
|
[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. |

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 |
|

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 |
|
------------|-------- |
|

|
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. |

|
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 |

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! |

8-bit cards ("Made in Taiwan R.O.C.") |
|
------------------------------------- |
|
|
|
- from Vojtech Pavlik <[email protected]> |
|
|
|
I have named this ARCnet card "NONAME", since I got only the card with |
|
no manual at all and the only text identifying the manufacturer is |
|
"MADE IN TAIWAN R.O.C" printed on the card. |

|
|
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 |
|
5 | ID4 | 16 |
|
6 | ID5 | 32 |
|
7 | ID6 | 64 |
|
8 | ID7 | 128 |
|
|
|

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 |
|
6 7 8 | Address |
|
------------|-------- |
|

|
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 (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 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 |
|
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. |
|
|
|

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 |

|
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... |

|
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 |
|
