4. Setup Instructions
Follow these steps to set up your BDFFLY HDMI Extender:
- Connect the HDMI Source to the Transmitter (TX): Use an HDMI cable to connect your HDMI source device (e.g., PC, game console, Blu-ray player) to the HD IN port on the Transmitter unit.
- Connect the Display to the Receiver (RX): Use an HDMI cable to connect your display device (e.g., TV, monitor, projector) to the HD OUT port on the Receiver unit.
- Connect Transmitter and Receiver with Ethernet Cable: Connect the UTP port on the Transmitter to the UTP port on the Receiver using a single Cat5e, Cat6, or Cat7 Ethernet cable. For optimal performance and reliability, a high-quality Cat6 cable is recommended.
- Connect Power Adapters: Plug one power adapter into the DC 5-12V port on the Transmitter and the other into the DC 5-12V port on the Receiver. Connect both power adapters to a power outlet.
- Local Loop-out (Optional): The Transmitter unit also features an HD OUT port. You can connect a local display to this port to monitor the HDMI source signal directly at the source location.

This image visually represents the straightforward plug-and-play nature of the HDMI Extender, showing a direct connection from a source device (laptop) to the transmitter, an Ethernet cable connecting the transmitter and receiver, and the receiver connected to a display (TV).
5. Operating Instructions
Once all connections are made and power is supplied, the BDFFLY HDMI Extender operates automatically:
- Power On: Ensure both the Transmitter and Receiver units are powered on. The PWR indicator LED on each unit should illuminate.
- Signal Detection: The extender will automatically detect the HDMI signal from your source device. The STA (Status) indicator LED will illuminate when a stable HDMI signal is detected and transmitted.
- EDID Copy Function: The extender features an EDID copy function that automatically identifies the display device parameters and matches them. This enhances compatibility with various devices and adapts to complex application environments. No manual configuration is typically required for EDID.
- Plug and Play: The system is designed for plug-and-play functionality, meaning no additional drivers or software are needed for operation.
6. Maintenance
To ensure the longevity and optimal performance of your HDMI Extender, please observe the following maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the units. Avoid using liquid or aerosol cleaners, as they may damage the casing or internal components.
- Ventilation: The units are equipped with heat dissipation ports. Ensure these ports are not obstructed to allow for proper airflow and prevent overheating.
- Environment: Keep the extender in a cool, dry place, away from direct sunlight, high temperatures, and excessive humidity.
- Cable Management: Ensure all cables are securely connected and not under undue strain. Avoid bending HDMI or Ethernet cables sharply.
7. Troubleshooting
If you encounter issues with your HDMI Extender, please refer to the following troubleshooting steps:
- No Picture/Signal:
- Ensure both the Transmitter and Receiver units are powered on and their PWR indicator LEDs are lit.
- Verify that all HDMI and Ethernet cables are securely connected.
- Check the quality and length of your Ethernet cable. High-performance Cat5e/Cat6/Cat7 cables are recommended, and ensure the length does not exceed 492 feet (150 meters).
- Test the HDMI source and display directly with a short HDMI cable to confirm they are functioning correctly.
- Try restarting both the source device and the display device.
- Poor Picture Quality/Flickering:
- Ensure you are using a high-quality Ethernet cable (Cat6 is preferred).
- Check for any electromagnetic interference (EMI) sources near the Ethernet cable.
- Verify that the resolution and refresh rate of your source device are supported by the extender (up to 1080P@60Hz).
- EDID Handshake Issues:
- If your display takes an unusually long time to identify the signal, ensure the display device is fully powered on and ready before powering on the extender or source.
- In rare cases, some source devices or displays may have specific EDID requirements. The extender's automatic EDID copy function typically handles this, but ensure all devices are compliant with HDMI 1.3 and HDCP 1.2 standards.
- LED Indicators:
- PWR LED: Should be lit when power is supplied. If not, check power adapter and outlet.
- STA LED: Should be lit when a stable HDMI signal is detected and transmitted. If not, check HDMI connections and source device output.
