2.11 Connectors Pin Assignment
The ACL-8316/12 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 used for digital signal output, CN2 for digital signal input, CN3 for
analog input, analog output and timer/counter's signals. The pin assignment
of each connector is illustrated in Figure 2.10~2.12.
