Cat. No. 868 Remote fader (CP750)

Of which I've been trying to find more information on... there's a manual but it doesn't show the circuit board interface cable connection that it references (missing figure 2). Not using the CP750 so working on the wiring to connect one to a Crestron Pro3 (via RS422) and use an external 15v DC power supply

It is a standard ethernet cable RJ45 connector. The CP750 has an RJ45 for the cable, they ship with a jack locking plug so one doesn't connect a network cable to it. I don'y know what that would do but since they bother with the lockout, it probably isn't good.
No clue on the communication protocol or command structure, I don't know if it's published. Not TCP/IP, at least.

Thanks for the response Dave. I understand it's an RJ45 connection, have the pinout from the CP750 manual which I'll attach here. Just can't find much data for the connection on the fader end..

Worst case I'll just figure it out once I get the fader in hand but would like to prepare ahead of time if possible.

That pin-out looks like it follows the standard POE wiring plan,
which reserves pins 4&5 + 7&8 for power transport.
