I got this from http://216.167.29.60/faqs/token-ring/ it works for my
PCMCIA to 8228 MAU connection
A DB-9 connector uses four wires (two pairs) for token ring networking:
Pin 1 - Red - Receive +
Pin 5 - Black - Transmit -
Pin 6 - Green - Receive -
Pin 9 - Orange - Transmit +
A RJ-45 connector is an eight wire twisted pair cable:
Pin 3 - Blue/White - Transmit -
Pin 4 - White/Orange - Receive +
Pin 5 - Orange/White - Receive -
Pin 6 - White/Blue - Transmit +
RJ45 DB9
3 9
4 6
5 1
