Is GTR 200 Stndby freq flip/flop from two GPS possible?
Garmin GTR 200 Standby
I have tandem seating and a GPS 660 mounted in the rear and a GPS 796 mounted up front. The only radio is a GTR 200. I plan to use the RS232 (out) from the 660 and use the touch screen to input frequencies to the standby freq via the RS232 in (pin 24) on the GTR 200 for the rear seat person.
The GPS 796 has the same capability for inserting into standby. It would be useful to have the same standby freq change capability from the 796 but there is only one RS232 In on the GTR 200.
1. Would it be possible to use ?On-Off-On? toggle switch to change which GPS is sending standby freq info to the GTR 200?
2. If it were feasible, would it be a problem to switch between the two GPS while all the electronics are turned on during flight? (The 232 signal interruption from one GPS to another would not "confuse" the GTR 200?)
Thanks, George
