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
