J1      Two 6-position Telephone Jack   (CN160TP only)

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:

    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 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.

UM9065L : ARCnet Controller

SW 1    : Shared Memory Address and I/O Base

        ON=0

        12345|Memory Address
        -----|--------------
        00001|  D4000
        00010|  CC000
        00110|  D0000
        01110|  D1000

        10010|  CC800
        10011|  DC800
        11110|  D1800

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.

** Acer **
8-bit card, Model 5210-003
--------------------------
  - from Vojtech Pavlik <[e-mail]> 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.
