I'm trying to add a DMC to an existing working system but when I connect the RJ45 cable leading to the remote panel the system shuts down. If I unplug the cable the system returns to life. Toggling the switch on the remote has no effect.
I've tried removing the short (small cable) that is connecting the left and middle points of the manual switch but that results in the system shutting down completely, remote or no remote.
The main switch on the Multiplus is set to 'on' as per the manual.
I'm using Cat 6 cable with 2 x RJ45 connectors.
Am I missing something?
