Smart port – telemetry
FrSky's series of sensors are a hub-less design. Smart Port (S.Port) uses a three wire physical bus comprising of Gnd, V+ and Signal. S.Port telemetry devices are daisy chained together in any sequence and plugged into the S.Port connection on compatible X and S and later series receivers. The receiver can achieve half duplex communication at a rate of 57600bps (F.Port and FBUS are faster) with many compatible devices through this connection with little or no manual set up.
