Instead of buying the partner cable, can I just use a phone jack for the partner port on the Vex Controller?
I think as long as you use a handset cable that has all 4 conductors you should be good. I don’t think there is any special wiring in the vex ones compared to a replacement handset cord.
Ok thanks!
It’s definitely nothing custom, however you still might not have any lying around. It’s not a phone to wall cord, it’s an old-style handset to telephone-base cord. They are 4p4c modular connectors, straight wired. (4p4c means 4 position 4 conductor. Standard phone cord is 6p6c.) This is sometimes labeled rj9, rj22, and occasionally rj10.
Here’s some on amazon:
