I would just set the one port to 'On' when it looses communication, and have the other 3 to 'Off' so they don't draw down the UPS

Yes I've tested it a few times. I've even unplugged the head unit as a test, and it takes maybe 20 seconds to revert to defaults but it works great, and it hand failed during testing. We had a power outage a few weeks back and the 'real' test was good too.
