Hi.
I have a single screen AFS 5600 in my RV7. I will have AFS-GPS on serial port #4
I will have AFS-Pilot Autopilot on serial port # 2 I will have AF-ARINC module on serial port #3 I will have Garmin GTN 650 on serial port #1

I want to use a ZAON XRX for traffic display on the AFS 5600 as I am not in USA for TIS input.
How can I connect The ZAON when all the serial ports are already used?
Can I piggy back more than one input on a serial port and which serial port would you piggyback with for the ZAON?
Can you plug the ZAON into one of the USB ports?
Regards Morris.
