First make sure have the UTP connected correctly. The jack labelled CMD STA should be connected to a UTP upstream back towards the command station or connected directly to the cab bus jack on the command station or a jack on the rear of the Power Cab Panel (PCP). If it is connected correctly and still does not work please continue reading below.
