MODULAR SMART SWITCH

B.2  Cable for IBM PC, PC/XT, AT, or Compatible

Parallel cables to connect from IBM compatibles to the Modular Smart Switch
require a 25-pin plug on both ends.  All lines should be connected “straight-
through” (that is, 1 to 1, 2 to 2, etc.).

B.3  Cable to 36-Pin Amphenol Connector

A standard IBM Centronics

®

cable with a DB25 plug and a 36-pin Centronics

plug is sufficient.
