WD/SMC 8003 Ethernet Card Jumper Settings

Don't you just hate searching for the jumper settings for your old Ethernet card? I got sick of losing my ratty photo copy page, so I have put it up on my own web page for the SMC8003 or the WD8003.

I/O Base Address - W1

There are 5 jumper positions, but the left most one is not used.

Address	Jumpers
0x200	`:XXXX`
0x220	`::XXX`
0x240	`:X:XX`
0x260	`:::XX`
0x280	`:XX:X`
0x2A0	`::X:X`
0x2C0	`:X::X`
0x2E0	`::::X`
0x300	`:XXX:`
0x320	`::XX:`
0x340	`:X:X:`
0x360	`:::X:`
0x380	`:XX::`
0x3A0	`::X::`
0x3C0	`:X:::`
0x3E0	`:::::`

The jumper settings are read with the card in the upright position. A ':' means that the jumper is removed, and a 'X' means that there is a jumper in that position.

IRQ Selection - W2

IRQ	Jumpers
2	`X:::::`
3	`:X::::`
4	`::X:::`
5	`:::X::`
6	`::::X:`
7	`:::::X`

Ethernet Jumper Options - W3

This is a block of jumpers that should either all be on or all be off.

All Jumpers	Ethernet Type
On	Thin (BNC) Ethernet
Off	Thick (AUI) Ethernet

Ethernet Version - W4

This jumper selects whether you are using the old Ethernet Version 1, or the current Ethernet Version 2.

Jumper	Version
Off	2 - Default
On	1

Segment Length - W5

The 8003 was able to be used on over-length Ethernet segments if this jumper was removed. I would recomend against this as I guess all other Ethernet cards on the same segment would have to be configures the same.

Jumper	Cable Length
Off	Optional 300-meter segment
On	Standard Thin Ethernet segnemt - Default
