2 SIGNAL CONNECTION
2.1 CONNECTOR DIAGRAM
The CIO-DAS16 analog connector is a 37-pin, D-type connector accessible from the rear of the PC through the expansion
backplate (Figure 2-1). The signals available are identical to the DAS-16, or optionally, an additional signal, SS&H
OUT, may be accessed at pin 26.
Figure 2-1. Analog Connector
If frequent changes to signal connections or signal conditioning is required, please refer to the information on one of the
following:
O CIO-TERMINAL screw terminal board
O CIO-EXP16, 16-channel analog multiplexer
O CIO-SSH16 16-channel simultaneous sample & hold board
O ISO-RACK16, 16-module 5B isolation module interface rack
The CIO-DAS16 digital connector is identical to the CIO-DIO24 connector except for the
−
12V and +12V power signals
and interrupt input brought out on the CIO-DIO24. These are no-connect pins on the CIO-DAS16.
The digital connector is mounted at the rear of the CIO-DAS16 and will accept a 37-pin, D-type female connector such as
those on the C73FF-2, two-foot cable with connectors.
