5. Configuration et installation
Follow these steps to set up your FeinTech HX240 HDMI Extender:
- Connect the HDMI Source: Connect an HDMI cable from your source device (e.g., PC, game console) to the HDMI IN port sur l'unité émettrice (TX).
- Connect the HDMI Display: Connect an HDMI cable from your display device (e.g., TV, projector) to the SORTIE HDMI port sur l'unité réceptrice (RX).
- Connectez le câble réseau : Use a single high-quality CAT6 or CAT7 network cable to connect the SORTIE RJ45 port on the Transmitter (TX) unit to the ENTRÉE RJ45 port on the Receiver (RX) unit. Ensure the cable is properly terminated and meets the required specifications for the desired distance and resolution.
- Connect IR Cables (Optional):
- To control the source device from the display location: Connect the IR Receiver cable to the IR DANS port on the Receiver (RX) unit and place its eye near your display. Connect the IR Transmitter cable to the Sortie infrarouge port on the Transmitter (TX) unit and place its emitter eye near the IR sensor of your source device.
- To control the display device from the source location: Connect the IR Receiver cable to the IR DANS port on the Transmitter (TX) unit and place its eye near your source device. Connect the IR Transmitter cable to the Sortie infrarouge port on the Receiver (RX) unit and place its emitter eye near the IR sensor of your display device.
- Appliquer la puissance : Connectez les deux adaptateurs secteur 12 V CC fournis à 12 V CC input ports on both the Transmitter (TX) and Receiver (RX) units. Plug the power adapters into electrical outlets.
- Mise sous tension : Power on your HDMI source device and display device. The extender units are plug-and-play and should establish a connection automatically.

IR cables are also shown connected for remote control pass-through.
6. Mode d'emploi
The FeinTech HX240 HDMI Extender operates on a plug-and-play principle, requiring no special software or drivers. Once all connections are made and power is supplied, the units will automatically detect the signal and begin transmission.
6.1. Transmission du signal
The extender will transmit the HDMI signal from the source to the display. Ensure your source device is outputting a compatible resolution and refresh rate for your display and the extender's capabilities (up to 4K 120Hz HDR).
6.2. Transmission IR
The IR pass-through function allows you to control your source device from the display location or your display device from the source location using your existing remote control. Point your remote at the IR receiver eye, and the signal will be transmitted through the network cable to the IR emitter at the other end, controlling the respective device.
