I have pixracer with GPS to GPS port, telemetry to telemetry1, OSD to telemetry2 and I want to connect second GPS. At http://ardupilot.org/copter/docs/common-pixracer-serial-names.html is the second GPS port on SERIAL4_ What is the label of this hardware connector?
Thank you
It should be the FrSky port labeled on the board.
I’ve tried to connect a second GPS to the Serial 4 / FrSky port but even though the serial mapper says the port is configurable, I cannot connect the GPS unit successfully. I can connect the GPS to serial 1-3 (TELEM1, TELEM2, and GPS labeled ports on the board).
Have you successfully connected a GPS to FrSky on Serial 4?
I think the Pixracer FrSky port has an internal inverter, unlike the other serial ports.
