- Connect Transmitter: Connect your HDMI source device (e.g., laptop, Blu-ray player) to the HDMI IN port of the transmitter unit using an HDMI cable.
- Connect Receiver: Connect your HDMI display device (e.g., TV, projector, monitor) to the HDMI OUT port of the receiver unit using an HDMI cable.
- Power On: Connect the provided DC 12V power adapters to both the transmitter and receiver units, then plug them into power outlets. The PWR LED on both units should illuminate.
- Establish Link: The transmitter and receiver units will automatically attempt to establish a wireless link. Once connected, the LINK LED on both units will illuminate steadily.
- KVM Setup (Optional): If using KVM functionality, connect your keyboard and mouse to the USB ports on the receiver unit. Connect the USB PC port on the receiver to your computer (source) via a USB cable.
- Verify Signal: Ensure your display device is set to the correct HDMI input. The video and audio from your source device should now be displayed wirelessly.
