40-pin to 37-pin signal mapping

Signal mapping on the C40-37F-x and the BP40-37 cables is not 1:1. The following table lists the pin numbers
of the signals on the 40-pin end and the pin numbers of the associated signals on the 37-pin end.

For digital signal conditioning, you can connect the BP40-37 cable to a C37FF-x or C37FFS- x cable, and then
connect one of these cables to the 37-pin connector on MCC’s digital signal conditioning boards. Refer to page
16 for a list of compatible boards.
