5. Installatie en installatie
Follow these steps to set up your J-Tech Digital HDMI Extender:
- Kabels voorbereiden: Ensure you have a high-quality Cat5e, Cat6, or Cat7 Ethernet cable of the appropriate length (up to 120m/394ft). Also, have your HDMI cables ready.
- Sluit de HDMI-bron aan op de zender: Connect an HDMI cable from your source device (e.g., DVD player, game console, PC) to the HDMI-ingang poort op de zendereenheid.
- Sluit het HDMI-scherm aan op de ontvanger: Connect an HDMI cable from your display device (e.g., HDTV, projector) to the HDMI-uitgang poort op de ontvangereenheid.
- Ethernetkabel aansluiten: Connect one end of the Cat5e/6/7 cable to the Ethernet-poort on the Transmitter unit and the other end to the Ethernet-poort on the Receiver unit.
- IR-kabels aansluiten (optioneel):
- Sluit de IR TX Cable naar de IR TX Port on the Transmitter unit. Position the IR emitter head near the IR sensor of your source device.
- Sluit de IR RX Cable naar de IR RX Port on the Receiver unit. Position the IR receiver head in a location where it can receive signals from your remote control.
- Vermogen toepassen: Connect the two included 5V power adapters to the Power Ports (DC/5V) on both the Transmitter and Receiver units, then plug them into power outlets. The Power Indicator LEDs on both units should illuminate.
- Controleer de verbinding: Once all connections are made and power is supplied, turn on your HDMI source and display devices. The Status Indicator LEDs on both units should show a stable connection, and the video should appear on your display.

5.1 Multi-Receiver Application (via Ethernet Switch)
This extender supports a one-to-many configuration using an Ethernet switch. To achieve this, connect the HDMI Transmitter to an Ethernet switch, and then connect multiple HDMI Receivers to the same Ethernet switch. Each Receiver will then connect to its respective display.
Image: Diagram showing the J-Tech Digital HDMI Extender in a multi-receiver setup. A laptop (source) connects to the Transmitter, which then connects to an Ethernet switch. Multiple Receiver units are connected to the switch, each feeding a separate display, extending the signal up to 400ft.
6. Gebruiksaanwijzing
Once the setup is complete, the extender operates automatically. Ensure all devices are powered on in the correct sequence (source, then extender units, then display) for optimal performance.
6.1 IR Control Functionality
The IR extension feature allows you to control your HDMI source device from the location of your display. Point your remote control at the IR Receiver head connected to the Receiver unit. The signal will be transmitted through the Cat cable to the IR Emitter head connected to the Transmitter unit, which then relays the command to your source device.

7. Onderhoud
- Clean the unit with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Keep the unit free from dust and debris to ensure proper ventilation.
- Controleer regelmatig of de kabelverbindingen goed vastzitten.
8. Probleemoplossing
If you encounter issues with your HDMI Extender, refer to the following common problems and solutions:
| Probleem | Mogelijke oorzaak | Oplossing |
|---|---|---|
| No video or audio on display. | Loose cable connections, power issue, incorrect input selection on display. | Check all HDMI and Ethernet cable connections. Ensure both Transmitter and Receiver units are powered on. Verify the display is set to the correct HDMI input. Try restarting all devices. |
| Poor video quality (flickering, distortion). | Low quality or damaged Cat cable, excessive cable length, interference. | Use a high-quality Cat6 or Cat7 cable. Ensure cable length does not exceed 120m (394ft). Avoid running Cat cable near strong electrical interference sources. |
| De infrarood afstandsbediening werkt niet. | IR emitter/receiver misaligned, IR cables not connected properly. | Ensure the IR emitter is directly over or very close to the IR sensor of the source device. Confirm the IR receiver is positioned to receive signals from your remote. Check that both IR cables are securely plugged into their respective ports. |
| Power indicator not lit. | De voedingsadapter is niet aangesloten, het stopcontact is defect. | Ensure the power adapter is securely connected to the unit and a working power outlet. Try a different power outlet. |
