Workstation Connection Cables
For RJ-45 connectors, use the standard AM-359-50 cable set or straight RJ-45 patch cords. The
RJ-45 connectors use the same pin-outs as DB-9 connectors.
RS-232 pin assignments for connecting an IBM PC-compatible workstation to the Alpha Micro
computer are listed in the tables below.
