(1) Ensure the gimbal servos are unobstructed, failure to do so may damage the servo.
(2) Clear the obstacles at once if the operating gimbal is being blocked.
(3) Always mount camera before powering on the gimbal.
3. Insert washers into securing pins to lock the damping unit in place.
4. Plug the 8-pin cable from the Phantom 2 to the Phantom 2 port on the anti-interference enhancement
board, then connect the H3-3D port on the anti-interference enhancement board with the 8-pin port on
the gimbal via the supplied 8-pin cable.
Caution:
(1) Aircraft and accessories are not included with gimbal.
(2) Camera must be aligned with the nose of the aircraft.
(3) Gimbal is calibrated before delivery. Do not attempt to adjust or calibrate it yourself.
(4) Do not attempt to remove screws in the gimbal, which may result in reduced performance or even
damages.
(5) Do not unplug any cable attaching to the gimbal ports, or change the mechanical structure of the gimbal.
Connect to G8 pin port on the gimbal for signal transmission
Connect to PC to upgrade firmware using Assistant Software
Connect to flight control system
Connect to wireless video downlink module
Notes:
(1) Skip this chapter if you purchase the Phantom 2 version of H3-3D gimbal, as it does not come with GCU.
(2) GCU must be connected to the flight control system before it is powered on.
(3) Be sure to mount the camera onto the gimbal before power on the aircraft and the gimbal. Otherwise it
might damage the servo due to the incorrect center of gravity setting.
(4) Re-calibrate the remote controller when NAZA-M firmware is upgraded.
(5) Ensure all the connection is correct, otherwise it might causes damage to the gimbal or the flight control
system.
2 GCU Connection
2.1 Connect GCU and Flight Control System
GCU can either be vertically or horizontally installed on the Phantom 2. Follow the procedure below to complete
the connection between the GCU and flight control system.
Step 1. Upgrade the firmware of the flight control and the Assistant Software to the latest version (as shown in the
1. Solder the Video Signal/GND cables to wireless video transmission module (air system).
2. Plug the gimbal video signal cable jack into the GCU video signal port.
Notes
(1) Ensure to connect the wireless video transmission unit to the GCU before powering on the aircraft.
(2) It is recommended to use standard gimbal video signal cable. Make sure you solder the gimbal video
signal cable to the wireless video transmission module firmly. Insulated all the cables to prevent short
circuiting.
Leave as-is
Video Signal Cable(AV)
GND Cable
(3) GCU does not provide power to the wireless transmission module. Refer to the wireless video
transmission module manual for details on the power supply connection.
Tips:
(1) The below diagram shows the how video signal flows from the on-board camera to the gimbal.
(2) Should error occurs, examine each checkpoints on the below diagram to locate the source of the
problem.

Wireless video transmission transfers video signal from the on-board camera to the GCU via the gimbal video
signal cable. Follow the figure below to complete the connection.
1. Ensure your computer has access to the internet.
2. Close all the other applications (anti-virus application or firewall) before upgrading the firmware.
3. Make sure the power supply is securely connected. DO NOT unplug the power supply before the
upgrade completes.
4. Connect the GCU to PC through a Micro-USB cable, DO NOT disconnect the cable until firmware
upgrade completes.
5. Launch the Assistant Software and wait until connection is established.
6. Select UpgradeMain Control, IMU and CMU.
7. DJI Innovations server will check the current firmware version,
8. If a newer firmware is detected, the Assistant Software will download the upgrade the firmware
automatically.
9. Wait until the firmware upgrade completes.
10. Click OK and power cycle the system to finish the upgrade process.
Notes:
(2) CMU stands for “Camera Multi Unit”, which is management module for the camera.
(3) To eliminate the interference from the master control, it is recommended to disconnect the CAN-Bus
cable between GCU and master control before you upgrade the IMU or CMU.
(4) Double check the parameters once you have finish upgrading the firmware.
(5) Repeat (1) to (4) when the DJI server experiences heavy traffics or firmware upgrade fails.
3.4 Firmware & Software Upgrade
3.4.1 Firmware Upgrade
Follow the below procedures to upgrade the firmware upgrade, failure to do so might damage the gimbal:
3.4.2 Software Upgrade
Click Info Software Info, if the latest version is higher than the current version, you are advised to upgrade the
Assistant Software.
Obtain the serial number of the gimbal by clicking the “Info”“SN”. SN is a 32 digits authorization code that is
used to activate the gimbal. This authorization code has been filled at the manufacturing site when before its
shipment. You might be prompted to fill a new SN if you purchase a new feature in the future. If you fills an invalid
SN for more than 30 times, the gimbal will be locked and you have to contact our customer support to unlock the
For safety reasons, check of the following items before each flight:
(1) Gimbal is firmly installed to aircraft, and camera mounted correctly. Make sure the camera is aligned
parallel with nose direction of the aircraft.
(2) All cables are firmly and correctly connected.
(3) Ensure gimbal video signal cable is in solid soldering condition.
(4) Make sure the wireless video transmission module is connected to GCU before powering on the system.
(5) Transmitter is properly configured.
(6) Camera connection is correct.
(7) GCU and flight control system connection is correct.
(8) Flight control firmware version is latest.
1. Ensure all the batteries are fully charged.
2. Switch on the transmitter.
3. Power on the camera first then power on the gimbal and wait until gimbal self-test completes.
4. Initialization completes, camera lens point to aircraft nose direction, that is, the three axes of gimbal
should be in the condition as the above diagram shows.
5. Toggle the tilt control switch on your transmitter, and make sure it is working properly. Then try to feel if
your gimbal moves to the corresponding direction. If not, check your settings.
6. When finishing test, power off the gimbal first then the camera.
