S.BUS: Control port for the gimbal, which can be connected to a flight controller compatible with
the S.BUS protocol or directly to an Air Unit receiver for the purpose of controlling the camera
gimbal. S.BUS properties can be configured using the CONNEX Management application, which runs
on the computer connected to the Ground Unit, as described in
Chapter 4, CONNEXTM

This port should only be connected to the gimbal’s S.BUS of D.BUS port.

MAVLink-supported flight controller overlaid on an On Screen Display (OSD). Telemetry information
includes flight mode, number of connected GPS satellites, speed, height and more. To receive
telemetry data on Ground Unit, the Air Unit should be connected to the aircraft’s telemetry port.
