5. Setup Instructions
Follow these steps to set up your OREI EX-170C HDMI Extender:
- Connect HDMI Source to Transmitter: Use an HDMI cable to connect your HDMI source device (e.g., DVD player, PC, game console) to the HDMI In port on the Transmitter (TX) unit.
- (Optional) Connect Local Display: If you wish to monitor the source signal locally, connect an HDMI cable from the HDMI Out (Loop-Out) port on the TX unit to a local display.
- Connect Remote Display to Receiver: Use an HDMI cable to connect your remote display (e.g., TV, projector) to the HDMI Out port on the Receiver (RX) unit.
- Connect Ethernet Cable: Connect a single CAT5e/6/7 Ethernet cable between the CAT5/6/7 Out port on the TX unit and the CAT5/6/7 In port on the RX unit. Ensure the cable is properly terminated and within the recommended length (up to 164 feet).
- Connect IR Cables:
- Plug the IR Blaster cable into the IR Out port on the TX unit and position the IR emitter eye near the IR sensor of your HDMI source device.
- Plug the IR Receiver cable into the IR In port on the RX unit and position the IR receiver eye where your remote control will be used.
- Apply Power: Connect one of the provided 5V DC power adapters to the DC5V port on the Transmitter (TX) unit. Due to Power over Cable (PoC) functionality, only the TX unit requires power, and it will power the RX unit through the Ethernet cable.
- Power On Devices: Power on your HDMI source device and all connected displays. The extender should automatically establish the connection.

6. Operation
6.1 Basic Operation
Once all connections are made and power is applied, the extender will automatically detect the HDMI signal and transmit it to the remote display. Ensure both the source and display devices are powered on and set to the correct HDMI input.
6.2 EDID Management (Transmitter Unit)
The EDID (Extended Display Identification Data) switch on the transmitter unit allows you to manage the display's capabilities reported to the source device. This can be useful in resolving compatibility issues or ensuring the desired resolution is outputted. Refer to the specific EDID settings in the full PDF manual if you encounter display issues.
6.3 EQ Adjustment (Receiver Unit)
The EQ (Equalization) switch on the receiver unit is used to compensate for signal degradation over long Ethernet cable runs. If you experience flickering, signal loss, or poor picture quality, adjust the EQ switch to optimize the signal. Start with the lowest setting and gradually increase it until a stable and clear picture is achieved.
6.4 IR Control
The IR pass-through feature allows you to control your HDMI source device from the remote display location. Point your source device's remote control at the IR Receiver eye connected to the RX unit. The signal will be transmitted back to the IR Blaster connected to the TX unit, which will then relay the command to your source device.

8. Troubleshooting
If you encounter issues with your OREI EX-170C HDMI Extender, please refer to the following common solutions:
- No Picture/Signal Loss:
- Ensure all HDMI and Ethernet cables are securely connected.
- Verify that the power adapter is correctly connected to the TX unit and that the power indicator light is on.
- Check if the HDMI source and display devices are powered on and set to the correct input.
- Try a different HDMI cable or Ethernet cable to rule out cable defects.
- Adjust the EQ switch on the receiver unit to compensate for signal loss over long distances.
- Test with a shorter Ethernet cable if possible.
- Poor Picture Quality (Flickering, Distortion):
- Ensure you are using high-quality CAT6/7 Ethernet cables for optimal performance.
- Adjust the EQ switch on the receiver unit.
- Check the EDID settings on the transmitter unit if resolution issues persist.
- Reduce the resolution of the source device to see if the issue is resolved.
- IR Control Not Working:
- Ensure the IR Blaster eye is directly aligned with the IR sensor on your source device.
- Ensure the IR Receiver eye is positioned correctly to receive signals from your remote control.
- Check that the IR cables are securely plugged into the correct ports (IR Out on TX, IR In on RX).
- Intermittent Signal:
- This can often be caused by poor quality or overly long Ethernet cables. Use shielded (STP) CAT6/7 cables for best results.
- Ensure there are no strong electromagnetic interference sources near the cable run.
9. Maintenance
To ensure the longevity and optimal performance of your OREI EX-170C HDMI Extender, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the units. Avoid using liquid cleaners or aerosols, which may damage the components.
- Environment: Keep the extender in a cool, dry place away from direct sunlight, heat sources, and excessive moisture.
- Ventilation: Ensure adequate airflow around the units to prevent overheating. Do not block ventilation openings.
- Cable Management: Avoid bending or kinking HDMI and Ethernet cables sharply, as this can damage the internal wires and affect signal quality.
- Power Off When Not in Use: If the extender will not be used for an extended period, it is advisable to disconnect the power adapter.
