The COM 2000, because it emulates a Garmin SL40 via its serial port, should work fine with SkyView:
* Display primary and standby frequency on the top bar
* SkyView can send a standby frequency to the COM 2000
Note that while you can wire both COM 2000s to SkyView, SkyView will only interact with one of the two - you'll have to designate that one during setup.
The degree of compatibility with the INS 429 is uncertain. If it emulates a Garmin SL 30 via serial port, it should work fine with SkyView.
For wiring and setup of the COM 2000, follow the directions for Garmin SL40.
IF the INS 429 emulates a Garmin SL30 via serial port, follow the wiring and setup of the Garmin SL30.
I have a pair of VAL Avionics Com 2000 radios and a Val INS429. Are these compatible with Skyview?
