5. Setup and Installation
Follow these steps to properly set up your HDMI extender:
- Identify Units: Locate the Transmitter (Tx) unit and the Receiver (Rx) unit. The Tx unit has an HDMI input and a CAT6 output. The Rx unit has a CAT6 input and an HDMI output.
- Connect Source to Transmitter: Connect your HDMI source device (e.g., Blu-ray player, gaming console) to the HDMI INPUT port on the Transmitter (Tx) unit using a high-quality HDMI cable.
- Connect Display to Receiver: Connect your HDMI display device (e.g., TV, projector) to the HDMI OUTPUT port on the Receiver (Rx) unit using a high-quality HDMI cable.
- Connect CAT Cable: Connect a single CAT-6/6A/7 network cable (not included) between the CAT6 OUT port on the Transmitter (Tx) unit and the CAT6 IN port on the Receiver (Rx) unit. Ensure the cable is properly terminated and meets the specified category for optimal performance.
- Connect IR Cables (Optional):
- For controlling the source device from the display location: Connect the IR Receiver cable to the IR IN port on the Receiver (Rx) unit. Position the IR receiver eye where it can receive signals from your remote control. Connect the IR Emitter cable to the IR OUT port on the Transmitter (Tx) unit and place the emitter eye near the IR sensor of your source device.
- For controlling the display device from the source location: Connect the IR Receiver cable to the IR IN port on the Transmitter (Tx) unit. Position the IR receiver eye where it can receive signals from your remote control. Connect the IR Emitter cable to the IR OUT port on the Receiver (Rx) unit and place the emitter eye near the IR sensor of your display device.
- Apply Power: Connect one of the provided 5V DC power adapters to the DC 5V port on the Transmitter (Tx) unit. Due to Power over Cable (PoC) functionality, only the Transmitter requires external power.
- Power On: Power on all connected devices (source, extender units, display).
