40-pin to 37-pin signal mapping

Signal mapping on the C40-37F-x and the BP40-37 cables is not 1:1. Table 2-5lists 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-xor 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 2-10for a list of compatible boards.
