Button Functions
5-way Button
Ruby System: Push right to switch OSD interface. Press Down to confirm or open menu. Push up or down to navigate, and Push left to return to the previous menu.
OpenIPC System: Push up or down to change frequencies. Push right to adjust bandwidth (20MHz / 40MHz).
(Note: Button behavior may differ in future firmware versions.)
Record Button
Press to start or pause recording.
Flash Button
Press and hold the flash button, then connect DC power. After 2 seconds, release the button. The RX will enter flashing mode. Connect the RX to a computer via Type-C to begin the flashing process.
Connecting to Air Unit
Follow these steps to connect the WiFiLink-RX to an air unit and display:
- Install antennas for both WiFiLink 2 and WiFiLink-RX, then power both devices. Connect WiFiLink-RX to a display via HDMI cable.
- Once the device has booted up, use the 5-Way Button: push right to set the bandwidth to 20MHz, then push up/down to adjust the frequency to 5805MHz (this is the default frequency).
- Wait about 10 seconds. Once the connection is established, the video feed will be displayed.
System Flashing
Warning: Flashing the system will erase all files on the WiFiLink-RX's internal storage (eMMC) and TF card. Please back up important data in advance.
A. Obtaining the System Image file
- Open the provided link (e.g., GitHub repository) to select the target version and locate the image file with the `.img.xz` extension.
- Extract the downloaded compressed file to obtain a system image file.
B. Flashing Software
- Download the compressed Driver&Tool file from the provided link (e.g., Google Drive).
- Extract the downloaded compressed file to obtain flashing software and drivers.
C. Installing Driver
- Open the `DriverAssistant_v5.0` folder and double-click `DriverInstall.exe` to execute it.
- Click "Install" to continue. The process takes a few seconds to finish. A confirmation message will appear.
D. Flashing System Image File
- Open the `RKDevTool_Release_v2.96` folder and execute `RKDevTool.exe`.
- Initially, the RKDevTool flashing tool will display “No devices found” as the WiFiLink-RX is not yet connected.
- Ensure the WiFiLink-RX is properly connected to the antenna and that the TF card is removed to prevent data loss.
- Use a SIM eject tool or a small screwdriver to press and hold the flash button, then connect DC power. Wait for 2 seconds, then release the button.
- Connect the WiFiLink-RX to the computer via a Type-C data cable.
- If the previous steps were completed correctly, the WiFiLink-RX will enter flashing mode, and the tool will display "One MASKROM device found".
- When the RX is in flashing mode, you need to select the paths for the Loader and Image files. Click the designated area to select the "Loader" file (e.g., `rk356x_spl_loader_ddr1056_v1.10.111.bin`).
- Click the area for the "Image" file and select the system image file (e.g., `radxa_1-9-7_mdns_wifilink_rx_250311.img`).
- Tick the "Write by address" option.
- Click "Run" to execute the flashing process. The tool will start flashing the firmware.
- The flashing process takes about two minutes to finish. Monitor the progress indicators in the RKDevTool window. A "Download image OK" message indicates completion.
