3. คำแนะนำในการตั้งค่า

Follow these steps to set up your OREI EX-165C HDMI Extender:

1. เชื่อมต่อแหล่งสัญญาณ HDMI: Plug an HDMI cable from your source device (e.g., Blu-ray player, game console) into the HDMI IN port on the Transmitter unit.
2. Connect Local Display (Optional): If you wish to have a local display near your source, connect an HDMI cable from the HDMI OUT (Loop) port on the Transmitter unit to your local display.
3. เชื่อมต่อสายเคเบิลอีเทอร์เน็ต: Connect a single Cat5e/Cat6/Cat7 Ethernet cable (up to 165 feet / 50 meters) from the แมวออก port on the Transmitter unit to the กสท port on the Receiver unit. Note: For optimal performance, use high-quality shielded (STP) Cat6 cable. This device requires a direct point-to-point connection and will not work over your home network.
4. Connect Remote Display: Plug an HDMI cable from the เอาต์พุต HDMI port on the Receiver unit to your remote display (e.g., TV, projector).
5. Connect IR Cables:
   • For IR control of the source device from the remote display location: Connect the IR Receiver cable to the ไออาร์อิน port on the Receiver unit and position its eye to receive signals from your remote control. Connect the IR Transmitter cable to the ไออาร์ออก port on the Transmitter unit and position its emitter over the IR sensor of your source device.
   • For IR control of the remote display from the source location (bi-directional): Connect the IR Receiver cable to the ไออาร์อิน port on the Transmitter unit and position its eye to receive signals from your remote control. Connect the IR Transmitter cable to the ไออาร์ออก port on the Receiver unit and position its emitter over the IR sensor of your remote display.
6. เปิดเครื่อง: Connect the provided 5V DC power adapter to either the Transmitter unit or the Receiver unit. Due to Power over Cable (POC) functionality, only one power adapter is required. The other unit will receive power through the Ethernet cable.
7. การตั้งค่า EDID: The Transmitter unit features an EDID switch. Set the EDID switch to use the directly connected monitor as the source for resolution information, especially during initial setup or troubleshooting. Once a stable signal is achieved, you may switch it back to the remote monitor if desired, unless the pass-through monitor is permanently attached.

4. คู่มือการใช้งาน

Once all connections are made and power is supplied, the extender system should automatically detect and transmit the HDMI signal.

การส่งสัญญาณ:

• Ensure both the source device and the display devices are powered on.
• The extender units will establish a connection and transmit the video and audio signal to the remote display.
• If using the HDMI loop out, the local display will also show the source content.

การควบคุมอินฟราเรด:

• To control your source device from the remote display location, point your remote control at the IR Receiver eye connected to the Receiver unit. The signal will be transmitted via the Ethernet cable to the IR Transmitter connected to your source device.
• To control your remote display from the source location, point your remote control at the IR Receiver eye connected to the Transmitter unit. The signal will be transmitted via the Ethernet cable to the IR Transmitter connected to your remote display.

5. การบำรุงรักษา

The OREI EX-165C HDMI Extender is designed for reliable operation with minimal maintenance. To ensure longevity and optimal performance:

• Keep the units in a cool, dry environment, away from direct sunlight, heat sources, and moisture.
• Clean the units with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
• Ensure all cables are securely connected and not under strain.
• Avoid blocking ventilation openings on the units.

6 การแก้ไขปัญหา

If you encounter issues with your OREI EX-165C HDMI Extender, refer to the following common solutions:

• No Video/Audio Signal:
  • Verify all HDMI and Ethernet cables are securely connected.
  • Ensure both the transmitter and receiver units are powered on (check LED indicators).
  • Confirm the Cat5e/Cat6/Cat7 cable is a direct point-to-point connection and not routed through a network switch or router.
  • Test with a different, shorter Ethernet cable to rule out cable issues.
  • Check the EDID switch setting on the transmitter. Try setting it to use the local display's EDID for a stable signal, especially during initial setup.
  • Cycle power to both the extender units and connected source/display devices.
• Flickering or Poor Picture Quality:
  • Ensure you are using a high-quality Cat6 or Cat7 cable, especially for longer distances. Some Cat5e cables may not provide optimal performance for 1080p over 165 feet.
  • Adjust the EQ (equalization) settings if available on your specific model (refer to the physical unit for any small switches). For longer cables, start with higher strength settings and gradually reduce; for shorter cables, start low and increase. Cycle power after each adjustment and wait for signal sync.
  • Reduce the resolution of the source device to see if the signal stabilizes.
• ระบบควบคุมอินฟราเรดใช้งานไม่ได้:
  • Ensure the IR Receiver eye is positioned correctly to receive signals from your remote control.
  • Verify the IR Transmitter emitter is directly over the IR sensor of the device you intend to control.
  • Check that the IR cables are securely plugged into the correct ports (IR IN on the receiving end, IR OUT on the transmitting end).
• Power Issues (POC):
  • If only one power adapter is used, ensure it is connected to either the transmitter or receiver. Both units should power on.
  • If cycling power to the receiver unit when POC is active, unplug both its power adapter (if connected) and the Ethernet cable to ensure a full reset.

หมายเหตุสำคัญ: It is highly recommended to test your setup with all cables and devices before performing any permanent installation or routing cables through walls or ceilings.
