3.7 Connector Diagram

The CIO-DAC##-I connector is a 37-pin D-type connector accessible from the rear
of the PC through the expansion backplate (Figures 3-5, 3-6).

The connector accepts female 37-pin, D-type connectors, such as those on the
C37FF-2, 2-foot cable with connectors.  

If frequent changes to signal connections or signal conditioning is required, refer to
the information on the CIO-TERMINAL, CIO-SPADE50 and CIO-MINI37 screw
terminal boards in the Measurement Computing catalog.
