3. Setup Guide
Follow these steps to set up your URayCoder HDMI encoder for operation.
3.1 Hardware Connection
- Connect HDMI Source: Use an HDMI cable to connect your video source (e.g., camera, set-top box, laptop) to the HDMI In port on the encoder.
- Connect Display (Optional): If you require a local display, connect an HDMI cable from the HDMI Out (loop-out) port on the encoder to your display monitor.
- Connect Audio (Optional): If using external audio, connect your audio device to the Audio In 3.5mm jack.
- Connect Network: Connect an Ethernet cable from the LAN port on the encoder to your router or network switch.
- Connect Power: Plug the 12V DC power adapter into the DC 12V port on the encoder and then into a power outlet. The Power LED should illuminate.

3.2 Accessing the Web Interface
After connecting the hardware, you can access the encoder's web interface for configuration.
- Ensure your computer is on the same network as the encoder.
- Open a web browser (e.g., Chrome, Firefox).
- Enter the encoder's default IP address in the address bar. (Refer to the device label or included documentation for the default IP address, typically 192.168.1.168 or similar).
- Log in using the default username and password (usually 'admin' for both, refer to documentation).
4. Operating Instructions
This section guides you through configuring the encoder via its web interface.
4.1 Status Page
Upon logging in, the Status page provides an overview of the encoder's current operation, including running time, input resolution, collected frames, and network status.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your URayCoder encoder.
5.1 General Care
- Keep the device in a cool, dry, and well-ventilated area.
- Avoid exposing the device to direct sunlight, high temperatures, or excessive humidity.
- Clean the exterior with a soft, dry cloth. Do not use liquid cleaners or aerosols.
- Ensure all cables are securely connected and not under strain.
5.2 Firmware Updates
Periodically check the URayCoder official website for firmware updates. Firmware updates can improve performance, add new features, or fix bugs. Follow the instructions provided with the firmware update package carefully to avoid damaging the device.
6. Troubleshooting
This section addresses common issues you might encounter and provides solutions.
6.1 No Video Output/Signal
- Check HDMI Cables: Ensure all HDMI cables are securely connected to both the source and the encoder. Try different HDMI cables if necessary.
- Verify HDMI Source: Confirm that your HDMI source is powered on and outputting a signal. Test the source with a direct connection to a display.
- Input Resolution: Ensure the input resolution from your source is supported by the encoder.
- HDCP: The encoder supports HDCP 1.4. If your source uses a higher HDCP version, it might cause compatibility issues.
6.2 Network Connection Issues
- Check Ethernet Cable: Ensure the Ethernet cable is properly connected to the encoder's LAN port and your router/switch.
- Network Configuration: Verify that the encoder's IP address, subnet mask, and gateway settings are correct and compatible with your network. If unsure, try resetting the encoder to factory defaults (refer to the reset button on the front panel).
- Firewall/Router: Check your network firewall or router settings to ensure they are not blocking the encoder's communication.
6.3 Streaming Problems (Buffering, Disconnections)
- Network Bandwidth: Ensure your internet connection has sufficient upload bandwidth for your chosen video bitrate and resolution.
- Encoder Bitrate: Reduce the video bitrate in the encoder settings if your network bandwidth is limited.
- Streaming Platform Settings: Verify that the streaming settings (stream key, server URL) on the encoder match those provided by your streaming platform.
- Router/Switch Performance: A congested or underperforming router/switch can cause issues. Try connecting the encoder directly to a high-performance network port if possible.
