4. Opsætning og installation
Follow these steps for proper installation of your PWAYTEK 4K HDMI Extender:
4.1 Kontroller før installation:
- Ensure the output resolution of your HDMI source device is set to not exceed 3840x2160P@60Hz.
- Connect your HDMI source directly to your display to confirm that both devices are functioning correctly and producing an image output.
4.2 Connection Diagram:

4.3 Trin-for-trin installation:
- Tilslut HDMI-kilde: Connect an HDMI cable from your source device (e.g., PC, TV Box, Camera) to the HDMI-IN porten på senderenheden.
- (Optional) Local Display Connection: If a local display is desired, connect an HDMI cable from the HDMI-UDGANG (Loop-udgang) port on the Transmitter unit to your local monitor or TV. This allows you to view the content near the source.
- Tilslut Ethernet-kabel: Connect a single Cat5e/6/7 Ethernet cable between the UTP port on the Transmitter unit and the UTP port on the Receiver unit. Ensure the cable is properly terminated using the 5680B crimping method for optimal performance.
- Tilslut HDMI-skærm: Tilslut et HDMI-kabel fra HDMI OUT port on the Receiver unit to your remote display device (e.g., TV, Monitor, Projector).
- Tilslut IR-kabler (valgfrit): If using IR pass-through, connect the IR Blaster cable to the IR UD port on the Transmitter unit and position the emitter near your source device's IR sensor. Connect the IR Receiver cable to the IR IN port on the Receiver unit and position the receiver where your remote control will be used.
- Anvend strøm: Connect the provided 5V/1A power adapters to the DC 5V ports on both the Transmitter and Receiver units. Power indicators should illuminate.

5. Betjeningsvejledning
Once all connections are securely made and power is applied to both units, the PWAYTEK 4K HDMI Extender should automatically establish a connection and transmit the HDMI signal. No additional configuration is typically required due to its EDID auto-matching feature.
- Tænd: Ensure both the Transmitter and Receiver units are powered on. The power indicator lights should be active.
- Signaloverførsel: The video and audio signal from your source device will be transmitted to the remote display.
- IR kontrol: If IR cables are connected, you can use your source device's remote control from the remote display location to control the source.
6. Fejlfinding
If you encounter issues during operation, please refer to the following troubleshooting tips:
- Intet billede/signal:
- Verify that both the Transmitter and Receiver units are powered on and their power indicators are lit.
- Check all HDMI and Ethernet cable connections to ensure they are secure and correctly plugged in.
- Ensure the Ethernet cable is Cat5e/6/7 and is not exceeding the maximum recommended length (60m for 4K@60Hz).
- Confirm that the HDMI source device is outputting a signal and that its resolution is supported by the extender and the display (up to 4K@60Hz).
- Test the HDMI source directly connected to the display to rule out issues with the source or display.
- Poor Picture Quality/Flickering:
- Ensure high-quality HDMI cables are used, especially for connections between the source/display and the extender units. HDMI 2.0 cables are recommended, ideally within 3 meters (10 feet).
- Check the quality and termination of the Ethernet cable. A damaged or poorly terminated cable can affect signal integrity.
- Reduce the resolution of the source device to see if the issue persists.
- IR-kontrol virker ikke:
- Ensure the IR Blaster and IR Receiver cables are correctly connected to their respective ports (IR OUT on TX, IR IN on RX).
- Verify that the IR Blaster emitter is positioned directly over the IR sensor of the source device.
- Ensure the IR Receiver is positioned to receive signals from your remote control.
