User Manual

This example is based on a Z15-GH4 gimbal and the A2 flight control system.
1. Connect the Gimbal Port on the Lightbridge Air System to the G7 port on the Z15-GH4 GCU using the

supplied HD video power cable (7-pin cable).

2. Connect the DBUS port on the Lightbridge Air System to the DBUS port (X2 port) on the A2 flight control

system. Toggle the HD/AV switch to the HD position.

3. Refer to the Lightbridge and A2 flight control system manuals to complete the connection.

The HD video power cable is included with the Z15-GH4 gimbal. To transmit gimbal and aircraft

signals, connect the RC receiver to the DJI Lightbridge ground system when connecting the GCU.

Always connect the wireless video transmission module to the GCU before powering on.

A standard HD video power cable (7-pin cable) is recommended.

Complete the other connections according to the Lightbridge user manual.

If the gimbal LED indicator blinks red continuously, please power cycle the gimbal. (Power it off,

then power it back on)

If the video signal does not transmit, check each step.

Make sure to connect the wireless video transmission module and the iOSD Mark II cable to the GCU
before powering on.
