The CONNEX Gimbal Control feature enables an operator on the ground to control the drone's camera gimbal using various remote controls over the video uplink channel. Only gimbals that can input S.BUS are supported. Gimbal control is supported for up to 500 meters.

This feature is supported only when an Air Unit is paired with a single Ground Unit. Before beginning the procedure below, verify that this is the case by using the CONNEX Management application to check the Ground Units that are registered to the Air Unit (see Checking the Ground Units Registered to an Air Unit (Windows / MAC) and Configuring Fail Safe Parameters (Android)).

To enable the CONNEX Gimbal Control feature:

  1. Connect the Air Unit S.BUS/CTRL port to the S.BUS or D.BUS port on the camera’s gimbal using the provided Air Unit MAVLink Telemetry and S.BUS cable or Air Unit CAN bus Telemetry and S.BUS cable.

  2. Connect the gimbal remote control’s Trainer port to the Ground Unit’s S.BUS/PWM/PPM port using the S.BUS/PWM/PPM Port cable.

  3. The default gimbal command transmission bit rate is FASSTest 12CH Mode (6.3m sec). If this bit rate is not supported by the gimbal controller, use the CONNEX Management application to configure the S.BUS Bit Rate manually (see Checking the Ground Units Registered to an Air Unit (Windows / MAC) and Configuring Fail Safe Parameters (Android)).

The Ground Unit automatically detects the S.BUS/PWM/PPM and transmits the gimbal commands over the wireless return channel to the Air Unit’s S.BUS/CTRL port.

For a list of supported remote controls and gimbals, see Supported Remote Controls, Gimbals and Telemetry Flight Controllers.
