Port: Allows selection of the SmartPort on the receiver to use either S.Port, F.Port or the FBUS (F.Port2) protocol. The F.Port protocol was developed with the Betaflight team to integrate the separate SBUS and S.Port signals. FBUS (F.Port2) also enables one Host device to communicate with several Slave devices on the same line. For more information about the port protocol, please refer to the protocol explanation on the official FrSky website.
