What is the part # and pin-out of the cable that came with my MVI serial module?

The part number for reordering the RJ45 to DB9 adapter cable provided with PLC serial modules is Cable 14.

Pinout for the DB9 side:

This is a straight thru adapter cable, pin 1-1, 2-2, 3-3, etc. Pin 9 on the DB9 side is not used.

For the RJ45 side, while facing the module, the pins are numbered from 1 at the top to 8 at the bottom.
