Pinout - Main I/O Connector - Measurement Computing PCI-DUAL-AC5 User Manual

PCI-DUAL-AC5 User's Guide
If you need direct access to the digital I/O, use the C100FF-x series cables to connect two CIO-MINI50s,
an SCB-50 or a CIO-TERM100. These combinations bring all I/O connections out to convenient, easy-
to-use screw terminals
Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections (available at www.mccdaq.com/signals/signals.pdf).
Pinout – main I/O connector
The I/O connector for the board is a 100-pin header connector accessible from the rear of the PC through
the expansion backplate. See
The connector accepts 100-pin connectors, such as on the C100FE-2, a 2-foot cable with two edge-
connectors, or the C-100FF-2, a two-foot cable with two 50-pin header connectors.
