4. Setup Instructions

Follow these steps to set up your OREI UHD48-EX230-K HDMI Extender Matrix:

1. Prepare Cables: Ensure you have high-quality CAT5e/6/7 cables for extending the HDMI signal. For optimal performance, shielded CAT6 cable is recommended.
2. Connect HDMI Sources: Connect your HDMI source devices (e.g., Blu-Ray player, game console, streaming box, laptop) to the HDMI Input ports (INPUT 1-4) on the OREI Matrix using HDMI cables.
3. Connect Local Displays (Optional): If you wish to monitor any of the HDMI sources locally, connect a display to the corresponding HDMI Loop Out port (LOOP OUT 1-4) on the OREI Matrix.
4. Connect Receivers: Connect each of the four HDMI Receivers to the RJ45 Output ports (OUTPUT 1-4) on the OREI Matrix using your CAT5e/6/7 cables.
5. Connect Remote Displays: Connect your remote displays (TVs, projectors) to the HDMI Output port on each Receiver unit using HDMI cables.
6. IR Connections:
   • For controlling source devices from remote displays: Connect an IR Blaster cable to the IR OUT port on the Matrix and position the blaster head near the IR sensor of your source device. Connect an IR Receiver cable to the IR IN port on a Receiver unit and position the receiver head where it can receive signals from your remote control.
   • For controlling remote displays from the Matrix location: Connect an IR Blaster cable to the IR OUT port on a Receiver unit and position the blaster head near the IR sensor of your remote display. Connect an IR Receiver cable to the IR IN port on the Matrix and position the receiver head where it can receive signals from your remote control.
7. Connect Power: Connect the provided power adapter to the DC 12V port on the OREI Matrix. Only the main Matrix unit requires power, as the receivers are powered via Power over Cable (POC).
8. Power On: Power on all connected devices (sources, displays, and the OREI Matrix).

5. Operating Instructions

The OREI UHD48-EX230-K offers flexible control options to manage your HDMI sources and displays.

5.1. Front Panel Control

The front panel of the Matrix unit features buttons for selecting inputs and outputs. Use these buttons to route any of the four HDMI input sources to any of the four extended outputs or local loop-out ports.

5.2. Remote Control

Use the included IR remote control to switch between inputs and outputs. Point the remote towards the IR receiver window on the front panel of the Matrix unit.

5.3. IR Pass-Through

The bi-directional IR pass-through allows you to control source devices from the remote display locations or control remote displays from the Matrix location. Ensure IR blaster and receiver cables are correctly connected and positioned as described in the setup section.

5.4. RS-232 Control

For advanced control and integration with automation systems, connect a computer or control system to the RS-232 port on the Matrix using the provided RS-232 cable. Refer to the detailed RS-232 command set in the full product manual (if available) for specific commands.

5.5. EDID Management

The Matrix features advanced EDID management. This function helps ensure compatibility between your source devices and displays by communicating the optimal video and audio formats. Consult the full product manual for specific EDID settings and modes if you encounter display issues.

5.6. 1080P Downscaling

The unit supports automatic 4K to 1080P downscaling. If a connected display only supports 1080P, the Matrix will automatically convert the 4K signal to 1080P, ensuring compatibility without manual intervention.

6. Maintenance

To ensure the longevity and optimal performance of your OREI UHD48-EX230-K HDMI Extender Matrix, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the unit. Avoid using liquid or aerosol cleaners, as they may damage the enclosure or internal components.
• Ventilation: Ensure the unit is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Power: Disconnect the power adapter from the wall outlet if the unit will not be used for an extended period.
• Cable Management: Keep cables organized and free from kinks or excessive bending to prevent signal degradation or damage.
• Environment: Avoid exposing the unit to extreme temperatures, humidity, or direct sunlight.

7. Troubleshooting

If you encounter issues with your OREI UHD48-EX230-K, refer to the following common troubleshooting steps:

• No Picture/Signal:
  • Verify all HDMI and CAT cables are securely connected.
  • Ensure the Matrix unit is powered on and its indicator lights are active.
  • Check if the correct input source is selected on the Matrix and the correct HDMI input is selected on your display.
  • Test with shorter, certified HDMI cables directly connected to the source and display to rule out cable issues.
  • Try a different CAT cable, preferably a shielded CAT6/7 cable, as cable quality significantly impacts performance over distance.
  • Power cycle all devices (source, Matrix, receivers, display).
• Flickering or Intermittent Picture:
  • This often indicates a cable quality issue or signal degradation. Replace CAT cables with higher quality, shielded CAT6/7 cables.
  • Ensure the total cable length does not exceed the maximum recommended distance (230 feet).
  • Check for strong electromagnetic interference near the CAT cables.
• No Audio:
  • Verify audio settings on your source device and display.
  • Ensure HDMI cables support audio transmission.
  • Check EDID settings on the Matrix if configurable.
• IR Control Not Working:
  • Ensure IR blaster and receiver heads are correctly positioned and have a clear line of sight to the IR sensors of the devices they are controlling.
  • Check that IR cables are securely plugged into the correct ports (IR IN/OUT).
• 4K Signal Not Displaying on 4K TV:
  • Ensure your HDMI source is outputting a 4K signal.
  • Verify that your display supports 4K@60Hz and that its HDMI input is configured for enhanced format (e.g., HDMI 2.0, UHD Deep Color).
  • Use high-speed HDMI cables that support 4K@60Hz.

If these steps do not resolve the issue, please contact OREI customer support for further assistance.
