REXGEN OEM: pinouts and multiconnect cables

Updated

Find the pin of every REXGEN OEM signal on the logger connector and the 25-way D-Sub breakout. This guide also covers each lead of the 2-way and 5-way multi-connect cables.

How the cables fit together

REXGEN OEM has one JAE compact automotive 34-way connector. A breakout cable turns it into a female 25-way D-Sub connector and an RJ45 Ethernet socket. The multi-connect cables split the 25-way D-Sub into separate D-Sub leads. The breakout and both multi-connect cables are sold separately.
