2.9.1Pin Assignments of PCI-9112

The PCI-9112 comes equipped with two 20 -pin insulation displacement connectors - CN1 and CN2 and one 37-pin D -type connector - CN3. The CN1 and CN2 are located on board and CN3 located at the rear plate.

CN1 is for digital signal input, CN2 for digital signal output, CN3 for analog input, analog output and timer/counter's signals. The pin assignments for each connector are illustrated in the Figure 2.9.1~ Figure 2.9.3.
