After working fine for several days, now I cannot connect and the "radio" unit shows no power LED indication. Switching the "control" unit to the same supply lights up the LED on the control unit and I can reach the control unit via IP. There is no power indicator or communications with the radio unit on either supply. I have confirmed +12VDC at the power connector, and also noticed that the device labeled "X100F RRB2" just behind the power connector is very warm, even with the unit not operating. I assume this is hardware/repair issue not a setup problem? 73 John N5CQ
