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.
