MavLink PIn-out and CableSubmit a request
This article describes the pin-out of the MavLink cable.
The wiring is as follows:
Red wire-Tx (CONNEX transmitting)
Black wire-Rx (CONNEX receiving)
Note: In order to connect the CONNEX unit to another unit, there must be a cross between the Tx and the Rx of the other unit (i.e., the Tx of the CONNEX must be connected to the Rx of the other unit).
