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

1. เตรียมสายเคเบิล: Ensure you have high-quality CAT5e/6/7 cables for extending the HDMI signal. For optimal performance, shielded CAT6 cable is recommended.
2. เชื่อมต่อแหล่งสัญญาณ HDMI: 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. เชื่อมต่อตัวรับสัญญาณ: 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. เชื่อมต่อพลังงาน: 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. เปิดเครื่อง: Power on all connected devices (sources, displays, and the OREI Matrix).

7 การแก้ไขปัญหา

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

• ไม่มีภาพ/สัญญาณ:
  • 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.
• ไม่มีเสียง:
  • ตรวจสอบการตั้งค่าเสียงบนอุปกรณ์ต้นทางและจอแสดงผลของคุณ
  • Ensure HDMI cables support audio transmission.
  • Check EDID settings on the Matrix if configurable.
• ระบบควบคุมอินฟราเรดใช้งานไม่ได้:
  • 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.
