Try connecting to the 12V terminals on the SEM instead of the 4 way connector

When connected to 12V of the Slave if there is no power measure the voltage at the 12V terminals before connection and after connection of the UCMs and RIO

The wires to the UCM and RIO may be shorted or something on the UCM or RIO may be shorting

Remove the RIO and UCM one by one and see if the voltage recovers
