4. Funcionament
Funcionament bàsic
Once all connections are made and devices are powered on, the extender will automatically detect the HDMI signal and transmit it to the remote display. The system is designed for plug-and-play functionality, requiring no additional software or complex configuration.
Control IR
The one-way IR control feature allows you to control your HDMI source device from the location of your remote display. Simply point your source device's remote control at the IR Receiver (IR Rx) connected to the extender's receiver unit. The signal will be transmitted back to the IR Blaster (IR Tx) connected to the transmitter unit, which will then relay the command to your source device.

Gestió EDID
The extender provides an option to copy the EDID (Extended Display Identification Data) signal. This allows the source device to recognize the capabilities of either the local display connected to the transmitter's loop-out or the remote display connected to the receiver. This ensures optimal video and audio compatibility.

6. Guia de resolució de problemes
If you encounter issues with your OREI HDMI Extender, please refer to the following table for common problems and their solutions.
| Problema | Causa possible | Solució |
|---|---|---|
| No video output on remote display. | Loose cable connections, incorrect power, incompatible resolution, faulty Cat cable. | Check all HDMI and Cat6/Cat7 cable connections. Ensure the power adapter is securely connected and providing power. Verify that the source resolution is supported (not 2K). Test with a different Cat6/Cat7 cable. |
| Poor video quality (flickering, distorted image). | Low quality or damaged Cat cable, excessive cable length, interference. | Use a high-quality Cat6/Cat7 cable, preferably shielded (STP). Ensure cable length does not exceed 164 feet (50 meters). Minimize electromagnetic interference by keeping cables away from power lines. |
| El control per infrarojos no funciona. | IR cables incorrectly connected, IR emitter/receiver not positioned correctly, remote control issues. | Ensure IR Tx is connected to the Transmitter's IR OUT and IR Rx to the Receiver's IR IN. Adjust the position of the IR emitter to directly face the source device's IR sensor. Ensure the IR receiver is in line of sight of your remote control. Check remote control batteries. |
| Sense àudio. | Audio format not supported, loose HDMI cable. | Verify that the audio format is supported by both the extender and the display. Check HDMI cable connections. |
| El LED d'alimentació està apagat. | Sense corrent, adaptador de corrent defectuós. | Ensure the power adapter is securely plugged into a working power outlet and the extender unit. Try a different power outlet. If possible, test with another compatible power adapter. |
