Follow step-by-step installation instructions for the DJI O4 Air Unit and O4 Air Unit Pro.
Ensure proper power input and wiring to maintain stable performance and avoid damage.
Optimise video transmission module placement for better heat dissipation and signal reception.
Secure cables and antennas correctly to prevent interference and maximise transmission quality.
Use vibration absorbers and a lens bracket to improve image stability and protect components.
Proper installation of the DJI O4 Air Unit and DJI O4 Air Unit Pro ensures optimal performance and video transmission quality.
Follow these step-by-step instructions to correctly install and set up the unit while maintaining safe and efficient operation.
Pre-installation precautions
Handle with care: Avoid scratching electronic components on the circuit board to prevent damage.
Remove the lens protector before installation.
Use a lens bracket: A bracket is included, but you can install your own if preferred.
Add vibration absorbers to the video transmission module for improved stability.
Power input requirements
Air Unit | Power input range | Recommended power source |
|---|---|---|
O4 Air Unit | 3.7 to 13.2V | 5V output from the built-in BEC of the flight controller board. |
O4 Air Unit Pro | 7.4 to 26.4V | 9V output from the built-in BEC of the flight controller board. |
Cable connection guidelines
Check the cable sequence as different flight controllers may have varying wiring configurations.
Follow the wiring sequence instructions when connecting the 3-in-1 cable to the flight controller.
Installing the video transmission module
Position the module inside the aircraft body in a well-ventilated area.
Install near the propeller (within 1 cm) to improve heat dissipation.
Ensure contact with carbon fibre parts or heat dissipation accessories for better cooling.
Avoid overtightening screws to prevent stripping or damaging components.
Cable management
Organise and secure the coaxial cable to avoid interference.
Do not intertwine it with other wires or pull cables forcefully.
Avoid bending the end of the coaxial cable at a 180° angle, as this may impact video transmission performance.
Camera module installation
Position the camera module correctly, ensuring the side close to the coaxial cable faces up.
Enable Electronic Image Stabilisation (EIS): Note that mechanical vibrations may cause image shaking.
Use a vibration-absorbing bracket or soft rubber to reduce unwanted movement and stabilise footage.
Antenna positioning
Extend the antenna outside the aircraft frame for optimal signal reception.
Keep the antenna away from:
The video transmission module.
The camera module.
Metal or carbon fibre structural parts.
For DJI O4 Air Unit Pro: Position the two antennas at a 90° angle to enhance signal quality.
Installing a microSD Card
Insert a microSD card into the DJI O4 Air Unit Pro video transmission module for storage and recording capabilities.
Summary
Correct installation of the DJI O4 Air Unit and O4 Air Unit Pro ensures stable video transmission and improved performance.
By following these steps, you can achieve optimal heat dissipation, secure cable management, and strong signal reception.
