I/O Bus Expansion Cables
(Includes Instructions for Building Custom Length Cables)
Description
I/O bus expansion cables (IC693CBL300, 301, 312, 313, 314), called “Wye cables,” have a single
male 25-pin D connector on one end and a two-headed (one male, one female) 25-pin D connector
on the other end as shown in (A) of the figure. The 50 foot (15m) (IC693CBL302) cable has a
single male connector on the CPU baseplate end and a single terminated male connector on the
expansion baseplate end. The 3 foot cable (IC693CBL300) can also be used as a WYE adapter
cable to simplify building custom length cables (see the section “Cable Application Suggestions”
later in this Chapter).

Function of Cables
The I/O Bus expansion cables are used to extend the I/O bus to expansion or remote baseplates in
a Series 90-30 I/O system when additional I/O slots are needed or baseplates are required some
distance from the CPU baseplate. The prewired I/O bus expansion cables can be used for
connecting either expansion or remote baseplates. Where required cable length is not available in a
