You can use a long cable to connect the TX to the computer. For example if you
have the computer in the car, and want to run a few steps TX in hand to lauch
the plane.Two options :
1. Connect a 5 meters USB cable to the computer, and have the FTDI
adapter near the TX. (5 meter is the USB standard limit, else you’ll have
to insert an USB hub before going another 5 meters)
2. or you have the FTDI adapter on the computer, and have a long serial
cable. I’ve used 20 meters cable without issues.
IMPORTANT : disconnect the USB cable from APM when using telemetry
(when it’s connected, APM will default to 115200 bauds and we’re using the
same port for telemetry)
Remember that the Mission Planner communicates at 115200 bauds with the
OrangeRX TX module.
