Trying to install UR92 to Loconet. Everytime I try to insert the Loconet cable from the Command Station or PR3 to the UR92, the trains shut down. The track voltage drops to zero. The DCS100 peeps 4 times. The UR92 green LED heartbeat blinks as normal. The DT402D throttle is functioning normally. I am able to throw turnouts. Tested and tried many different cables thinking the wires were reversed. All wires check out. The problem occurs whether the UR92 is plugged into its power supply (PS14) or not. Again, the problem begins as soon as I insert the Loconet cable to the back of the UR92. As soon as I remove the cable, voltage to the tracks is restored and the trains function normally. I have reset the UR92 to factory settings many times. Please help...I'm stumped.
