Reaching out to the brain trust here as I contemplate some changes to my instrument panel setup.
Am currently using the Trig TC20 control head to control the remote-mounted TT22 transponder. This is working fine, other than what i perceive to be a challenge of legibility of the TC20's display. A future upgrade may well expand into the panel space currently occupied by the TC20.
At the moment the Mini-X is my stand-by EFIS, always left in PFD mode. It backs up a 6.5" HX which I use in PFD and split PFD/HSI/MAP modes. I don't have the GRT RS232/RS485 adapter to allow the HX to control the TT22 and I don't think I want to go that route as the HX is already very busy when I'm flying.
Bob Turner kindly informed me the most recent HX software includes a right-knob-hold feature to quickly access transponder controls so that might make using the HX to control the transponder.
I'll shortly be installing a third GRT EFIS, a Sport EX, over on the right side of the panel. It, too has the requisite RS485 interface to directly control the TT22 transponder, thus opening up the possibility to use the Sport EX as my transponder controller, but it will be located in front of the copilot.
I would like to hear from folks who use the GRT Mini-X to control the Trig TT22. Particularly I'd like to hear your impressions of the GRT transponder user interface.
Thanks for sharing your experiences!
