Warning & Disclaimer

No adjusting or amending is allowed to the H3-2D!!!

Before use, make sure to mount the camera to gimbal first, and then mount the

gimbal to aircraft. After this, you can power on the gimbal.

H3-2D is specialized for Camera and Lens before it leaves the factory. Please mount your camera to H3-2D when

get it. No adjusting or amending is allowed to H3-2D. Do not modify or add any other component/device (such as

filter, lens hood, etc.) to the camera; make sure to use the original battery; otherwise it may end up with worse

performance or even internal malfunction.

The gimbal can only work with Autopilot system specified by DJI Innovations (NAZA-M/NAZA-M V2/WooKong-M),

so as to ensure the highest stability and precision. Please download the corresponding assistant software and

upgrade the autopilot system MC firmware, otherwise may lead the gimbal work abnormally.

Make sure the Autopilot system operates in the safest manner when the main power battery is connected. We

strongly recommend customers to remove all propellers, use power supply from R/C system or flight pack battery,

and keep children away during gimbal calibration and parameter setup. Please strictly follow these steps to mount

and connect gimbal on your aircraft, as well as to install the assistant software on your computer. Please respect

the AMA’s National Model Aircraft Safety Code.

As DJI Innovations has no control over use, setup, final assembly, modification (including use of non-specified DJI

parts i.e. motors, ESCs, propellers, etc.) or misuse, no liability shall be assumed nor accepted for any resulting

damage or injury. By the act of use, setup or assembly, the user accepts all resulting liability. DJI assumes no

liability for damage(s) or injuries incurred directly or indirectly from the use of this product.

Product Profile

This product is an excellent gimbal designed for AP. Excellent job can be done by this gimbal. The gimbal has

built-in slip ring in the mechanical structure, preventing wire rod from winding up. It also has built-in

independent IMU (Inertial Measurement Unit) module, special servos drive module, etc.

In The Box

Gimbal×1

The gimbal has built-in special servos drive module, and

independent IMU module. It controls both the tilt and the roll axis,

to enhance the attitude stabilization.

Damping Unit×1

Connect the aircraft and the gimbal, in order to reduce the

mechanical vibration. There are three types of Vibration Absorber,

the White is softest, the Black is hardest, and the Grey is in the

middle. It is recommended to use the White on DJI F450, not use

any on DJI F550, and the DJI PHANTOM can use any type.

Gimbal Controller Unit (GCU)×1

Connect the gimbal controller to the autopilot system by

CAN-Bus. And Use the 3S~6S power cable to supply power for the

GCU and gimbal.

Screw Package ×1

M2.5x6.3: For fixing the camera to the gimbal.

M2.5x5: For fixing the gimbal to the damping unit.

M3x8 (with M3 nuts and M3 spacers): For mounting the damping

Gimbal Description

STEP1. Mount the Gimbal to the Aircraft or Landing Gear

The following procedure applies to DJI F450, DJI other type of aircraft or to your own aircraft. For DJI F450,

there are diagrams for your reference.

(1) This product does not include any extra aircraft, landing gear or camera, please prepare them by yourself. (2) Make sure the Camera Mounting Base is pointing to the aircraft nose direction. (3) The gimbal center of gravity has been set, whose position directly determine gimbal performance. Please

do not adjust the gimbal center of gravity by yourself.

(4) The gimbal is high-precision controlled. Do not remove any other screws in the gimbal, which may result

in bad performance or even damage.

(5) Do not unplug any cable attaching to the gimbal ports, or even change the mechanical structure. (6) The 8-pin port on the H3-2D gimbal should only be used for connecting to aircraft. Do not connect other

devices (such as a video downlink transmitter) to this port, otherwise the gimbal may be damaged.

SN is a 32 digits authorization code for unit function activations. We had already filled in the authorization code for

your unit after manufacture. You might be asking to fill in the new SN in the future if you brought new function

upgrades. Fill in the SN and then click Write button. If you filled in an invalid SN over 30 times, your product will be

locked and you have to contact our customer support.

Test

For safety reasons, please pay serious attention to all following items Before Every Flight.

(1) Gimbal is installed firmly to aircraft, and camera mounted correctly and stably. Make sure the Lens of

camera is pointing to the aircraft nose direction.

(2) All cables are in correct and firm connection, without anyone in backwards. (3) Gimbal video signal cable is in good soldered condition if wireless video transmission module used. Make

sure to connect Wireless Video Transmission Unit to GCU first, then power on.

(4) Correct TX settings. (5) Correct camera settings. (6) Normal connection between GCU and autopilot system. (7) Upgrade Autopilot System MC Firmware.

1. Make sure the batteries are fully charged for transmitter, GCU and all the other devices on your aircraft.

2. Switch on the TX.

3. Turn on the camera first then power up the gimbal and wait for gimbal self-testing.

4. After initializing, camera lens will 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, please power off the gimbal first then turn off the camera.

Note:

 If the gimbal is abnormal (unlike the diagram shows) after initializing, turn to

Trouble Shooting

in

Appendix

.

 Keep the power-on gimbal system still and horizontally during test. If you have to hold and move the

STEP1. Check List Before Every Flight

STEP2. Gimbal Test

aircraft with power-on gimbal, the inclination angle of the aircraft should not exceed 35°.

 Please do not land the aircraft with power-on gimbal on uneven ground (such as grass lawn or rocky

roads), in which environment there may have external forces act on the gimbal or the gimbal will get

shocked, then the gimbal will enter into Hibernation Mode.

 Hibernation Mode for gimbal protection. In the condition that the camera is not mounted on the gimbal

the gimbal will enter into Hibernation Mode, in which the gimbal is out of control from Transmitter. You

must mount the camera correctly and power cycle the system to activate the gimbal.

 Hibernation Mode for gimbal protection. When certain external forces act on the gimbal, it will enter

Hibernation Mode too. You must take notes to avoid too large forces affecting the normal working status

of gimbal and power cycle the system to activate the gimbal.

 It’s better to use separate battery pack to test the gimbal at the beginning to ensure functionality before

making steps to power on of flight controller, gimbal, OSD, FPV gears etc.

Settings Using with the A2 Flight Control System

Users should configure the H3-2D’s pitch control in the A2 assistant software when using with the A2 Flight

Control System. Map the H3-2D channel to a switch on the transmitter. It is recommended to use a Knob switch

channel, which is only used for H3-2D pitch control on the “Channel Map” page (as the following diagram shown).
