How can I wire the RMC-190 and PTC-120 via RS-422?
A: The RMC-190 and the PTC-120 have terminal block connectors (Phoenix connectors) which can be utilized for RS-422. We recommend using CAT5e or higher twisted pair (ethernet) cable to wire RS-422 camera control to each PTC-120 camera. The wiring diagram for RS-422 control is provided below.
Also,another way to look at the wiring is:
RMC pins 2345 go to PTC pins 9876
PTC pins 1234 go to 8967 for each camera
