Attaching power cables
Each RGB 400 Series interface requires an external voltage source of 12 to 24 volts AC or DC (250 mA maximum, 5 W). The interfaces are supplied with a power cord of twisted- pair wire soldered to the circuit board.
1.Splice these wires to the cord of a

Pre-installation testing/troubleshooting
Before installing the interface into the wall or furniture, test the system to make sure that the connections and interface settings are correct.
Turn on the input device(s) (computer, audio device) and output device(s) (projector and/or monitor, speakers). The image should now appear on the screen, and sound should be audible.
If the image does not appear or there is no sound
1.Ensure that all devices are plugged in.
2.Make sure that each device is receiving power. The interface’s Auto power indicator LED will light if the interface is receiving power and an active sync signal.
