# Gimbal Description

To avoid motor damage, ensure there is nothing blocking the rot ation of the servo drive modules. Clear obstacles or immediately cut off the power if any blockag e occurs. The servo drive modules have two motor command input ports and one private encoder port. The HDMI-HD/AV module converts HDMI to HD (or AV) using a cable connected to the camera HDMI port; it also transforms the TX signal into a shutter control s ignal by using a shutter control cable. The camera shutter control cable is removable. Unplug it if thi s functionality is not needed.

rudder control. Also, connect the TX’s AUX2 for aircraft control modes (Please refer to your Flight Control System’s user manual). 3. Choose three 3-position switches to use for the gimbal ROLL, TILT, and PAN rotation control. The center

position of each switch is 0 velocity, and the end point positi ons are maximum velocity. 4. Choose one 3-position switch/channel as the gimbal’s Working Mo des switch (MODE). 5. Choose one 2-position switch/channel as the camera shutter cont rol switch (SHUT). 6. Connect the receiver to the GCU and Flight Control System Main Controller correctly.

# 25 Troubleshooting

NO. The Problem The Cause What to Do

1 The gimbal keeps drifting after initialization. (1) The TX trims are too high. (2) The GCU and Flight Control System have been disconnected. (3) The gimbal direction is not pointing in the same direction as the aircraft’s nose. (1) Adjust the TX trims. (2) Connect the GCU and Flight Control System. (3) Ensure the gimbal direction is pointing in the same direction as the aircraft’s nose.

2 The gimbal is in an incorrect position after initializing. Abnormal calibration after manufacturing. Please contact your local dealer or DJI customer service.

3 Cannot distinguish the gimbal’s direction when in use. BVR (Beyond Visibility Range) flight. Switch to FPV Mode first, then to another Working Mode as needed.

4 The gimbal LED is blinking red. (1) There is a disconnected cable between the gimbal and camera. (2) The camera is off. (3) Camera setup failure. (1) Make sure all cables are securely connected. (2) Power on the camera. (3) Set the HDMI resolution to 1080i.

5 The gimbal’s green or yellow LED is continuously on, but no video is displayed. (1) The HDMI-HD/AV transmission module is disconnected from the camera. (2) The camera is powered off. (3) In HD mode, the DJI Lightbridge App video source has been set to “HDMI/AV”. (1) Check HDMI-HD/AV transmission module connection. (2) Power on the camera. (3) Change the DJI Lightbridge App video source to "HD Gimbal".Appendix
