Serial cable pinout for MTX-L over CAN

Post by WestfieldMX5 » Mon Mar 27, 2017 5:27 pm

I would like to read the MTX-L serial data over CAN but I'm not sure on the pinout.
The MTX-L has a 4pin Molex connector and a matching cable with DB9 as follows:
MTX-L black to DB9 pin 5 (GND)
MTX-L blue to DB9 pin 5 (GND)
MTX-L red to DB9 pin 3 (TXD)
MTX-L white to DB9 pin 2 (RXD)

If I cut off the DB9 and replace with a 2.5mm jack, do I connect like this?

MTX-L black and blue to the sleeve
MTX-L red to the tip
MTX-L white to the barrel
