The RUNCAM LINK Digital FPV Air Unit is an advanced video transmission module designed for use with racing drones. It facilitates wireless communication of video, control signals, and flight controller information, offering a comprehensive solution for drone piloting.

Function Description

The core function of the RUNCAM LINK Digital FPV Air Unit is to transmit a 5.8 GHz digital video signal, providing a high-quality 1280 x 720 60fps image transmission. This allows pilots to receive clear, real-time video feedback from their drone. The system boasts an impressive transmission range of up to 4 km and a remarkably low end-to-end latency, as little as 32 ms, ensuring a responsive and immersive piloting experience. This low latency is crucial for racing drones where split-second reactions are vital. The air unit is designed to be mounted on a racing drone and can be paired with DJI FPV Goggles for video display and a DJI remote controller for control. This integration allows for a seamless and intuitive piloting setup, where the pilot can view the drone's perspective and control its movements from a distance. The unit also transmits flight controller information wirelessly, providing essential data to the pilot for informed decision-making during flight.

Usage Features

The RUNCAM LINK Digital FPV Air Unit offers several features that enhance its usability and performance:

Connectivity: The air unit includes an IPEX Port Antenna for robust signal transmission, a Type-C Port for data transfer and activation, and a button for linking and other functions. It also features an LED indicator to provide status feedback.
Power and Ground Connections: The unit requires a power input ranging from 7.4-17.6 V, connected via a red wire. A black wire serves as the power ground.
UART Communication: It supports UART communication with the flight controller. A white wire connects to the Flight Controller OSD TX (0-3.3 V) for receiving data, and a gray wire connects to the Flight Controller OSD RX (0-3.3 V) for transmitting data. Another black wire is designated as the signal ground for these connections.
DJI HDL Integration: A yellow wire connects to the Flight Controller S.Bus (0-3.3 V), enabling seamless integration with DJI HDL for control signals.
Channel Management: The air unit supports up to eight channels, depending on the region (FCC: eight, CE/SRRC: four, MIC: three), each with a bandwidth of 20 MHz. Channel 8 is the default public channel upon power-on. Pilots can manually change channels to avoid interference from other devices, ensuring a clear and stable connection.
Activation: Before initial use, the air unit must be activated. This is done by connecting the powered-on air unit to a computer and running DJI ASSISTANTTM 2 software, which can be downloaded from the DJI website.
Linking Methods: The air unit supports three linking methods:
- Method A (Air Unit to DJI FPV Goggles): Power on both the air unit and the DJI FPV Goggles. Press the link button on both devices. A successful link is indicated by the air unit's linking status indicator turning solid green and the goggles ceasing to beep, with normal video display.
- Method B (Air Unit to DJI FPV Remote Controller): Power on both the air unit and the DJI FPV Remote Controller. Press the link button on the air unit, and simultaneously press the record button, C button, and right dial on the remote controller. Both linking status indicators will turn solid green upon successful linking.
- Method A+B: This method requires linking A before linking B, allowing the air unit to be connected to both the goggles and the remote controller.
Linking Indications: When ready to link, the air unit's linking status indicator turns solid red, the goggles beep continually, and the remote controller beeps continually with its status indicator blinking blue. These clear visual and auditory cues guide the user through the linking process.

Maintenance Features

While the manual primarily focuses on setup and operation, it includes important guidelines that contribute to the longevity and reliable performance of the device:

Soldering Precautions: When connecting cables, it is crucial to use an electric soldering iron and soldering tin. Users must ensure there are no short circuits or open circuits after soldering to prevent damage to the unit or other components.
Temperature Management: The air unit can become hot during or after operation. Users are advised not to touch the air unit until it has cooled down to prevent burns.
Overheating Prevention: To maintain optimal performance and prevent damage, the air unit should not be used for extended periods in high temperatures or areas with poor ventilation. Overheating can cause the unit to enter a low-power mode, affecting its performance. If this occurs, restarting the unit or allowing it to cool down will typically restore it to normal operation. This highlights the importance of proper ventilation and environmental considerations during use.
Technical Support: For any issues or questions, users are directed to the Runcam technical support website, providing a resource for troubleshooting and assistance.
