roaming | Can't find it in the 252 users manual, but I believe you only want power (12-32vDC) to one of the ports. I would hope, but wouldn't bet, that a piece of equipment this expensive is protected against overvoltage.
Not sure I understand the logic of what you want to do. Why not just supply switched power via a toggle or similar, and leave the switch closed all the time except when you want to shut everything down? Reading what you wrote, the switched power to Port A would be irrelevant, because the receiver would always be powered via the unswitched supply to Port B. | |
