Auto-calibration Function / Video Signal Transmission

Video Signal Transmission

A wireless video transmission module is required for remote video.

A. AV Wireless Video Transmission

1. Solder the AV Video Signal and GND cables to the wireless video transmission module air unit as shown above.
2. Plug the AV video power cable into the GCU’s G7 port.
3. Toggle the HD/AV Switch to the AV position. (See Page 7 for the location of the HD/AV Switch)
4. Power on the gimbal. If the gimbal LED indicator blinks yellow, it is functioning normally. If the LED indicator

shows a continuous, unblinking yellow light, the video signal is lost. Check the connections between the
camera and the HDMI video input.

Complete the connection between the wireless video transmission module and the GCU before

powering on the gimbal.

A standard AV video power cable is recommended.

Be sure to solder the AV video power cable to the wireless video transmission module correctly. As the

cable carries power, ensure the cables are insulated or wrapped to prevent a short circuit.

Connect the wireless video transmission module to a power source, as the GCU cannot supply power.

Make sure the power source provides a safe voltage for your own devices, according to the wireless
video transmission module’s requirements.

Auto-calibration Function

The auto-calibration function is new to the Z15-5D III (HD) gimbal. It can help solve vibration problems that
may be caused by the gimbal sensor drifting.

You can use the auto calibrate function when the following conditions are met:
1. The aircraft is on flat, level ground.
2. The landing gear is parallel to the aircraft IMU.
3. The initialization of the gimbal and aircraft is complete, and the gimbal is properly connected to the flight

control system.

To auto-calibrate the gimbal:
1. Move the MODE channel control stick up and down quickly. After about 3 seconds, the gimbal will buzz

twice and then begin auto-calibrating.

2. This process will last about 90 seconds. Do not touch the gimbal or aircraft during this time.
3. When the gimbal buzzes four times, the auto-calibration is complete. You can continue to operate the

gimbal normally at this time.
