VXR-7000 DSUB Channel Control

[iceman977th]

Out club has a VXR-7000 connected to an Arcom RC-210 controller. I have a macro set up for a power failure that changes the courtesy tone to let us know there has been a power failure, but we’d also like to reduce repeater power automatically to extend our runtime (we lasted about 2 and a half days at full power on two deep cycle batteries.. not bad, but with minimal use.. more batteries and a solar system on the way soon)

Ch 1 and 2 are set up the same, with Ch 2 being low power and Ch 1 being high power. However in Remote mode I know you cannot change the channel from the front panel. Pins 16-19 are channel control. Pulling Pin 19 to Ground would effectively change from Ch 1 to Ch 2 (in theory without needing 16-18 connected as they all stay high) but I do not know if that still works when in remote mode.

Does anyone know if the rear channel pins will work as intended while in Remote mode and this will work? I wanted to ask before I start wiring and programming the controller for it.

The only thing I'm familiar with is the Power dropped to 10W on DC, but I'll look.
CE27 for Windows
Common -> Radio Status -> DC TX Power Low = enabled

edit: It's channel steering only on pins 16-19. If you're running DC only the option above wouldn't work, but you could use a relay drop-out to steer to ch2.
Not a great idea, but you use a relay to switch the low power button on the front panel. I'm not familiar with your controller, but maybe an I/O of DC and momentary latch there?
