CIO-EXP32 User's Guide Installing the CIO-EXP32
Connecting to the A/D board
There are two 37-pin D type connectors on the CIO-EXP32 — P1 and P2. They are wired 1:1. Connector P1 is
labeled
NEXT EXP , and is provided to daisy chain additional CIO-EXP32 boards. Use a C37FF-x cable to daisy
chain the CIO-EXP32 boards together. Do not exceed 50 feet in length.
Signals may be connected from the CIO-EXP32 board to the A/D board through one of two types of cables. The
cable used depends upon the type of A/D board you are connecting to. The table below lists the CIO-EXP32
board's connectors and compatible cables.
