    AF5600 to GTN650 interface

    Is it possible to use the AF5600 com interface with a GTN650? If so, might you have a wiring diagram or info regarding how it needs to be wired?

    You would just need to wire a free serial port on the EFIS to a free serial port on the GTN. On the EFIS serial port assignment is GTR/GNC-2xx for pre 16.10.20 system software, or GTN COM for 16.10.20 and beyond. In the SET --> CAL --> COM radio menu radio type needs to be set to GNC-255 for pre 16.10.20 system software, or GTN COM for 16.10.20 and beyond.

    Lastly, on the GTN set the serial port that was wired to the EFIS as Radio CTRL Format 1.
