Issue Details

I have a NI 9237 module and a RJ50 Cable with 10-pin modular plug to pigtail wires. How do I determine which pin of the 9237 corresponds to which color of the RJ50 cable?


You can verify the order of the colors by looking through the clear connector on the RJ50 cable. Refer to the NI 9237 Operating Instructions and Specifications for 9237 pin assignments.
