2.8 Connector Pin Assignment
The ACL-6126 is equipped with one 37-pin D-sub (CN3) and two 20-pin
insulation displacement connectors (CN1 and CN2). The CN3 is located
at the rear plate; the CN1 and CN2 are located on board.
CN3 is used for analog outputs and reference voltage input, while CN2
for digital inputs and CN1 for digital outputs. Each connector's pin
assignment is specified as follows:
