3. Setup Instructions
The PWAYTEK Wireless HDMI system is designed for simple plug-and-play operation. Follow these steps for quick setup:
- Step 1: Connect the Receiver (RX)

Plug the Wireless HDMI Transmitter (TX) into the HDMI output port of your source device (e.g., laptop, PC, game console, camera). Connect the TX unit to a 5V/1A power supply using its USB cable. This can be a USB port on your source device or a separate USB power adapter. - Step 3: Automatic Connection
After connecting both the TX and RX units and ensuring they are powered, the product will automatically enter the connection page. Please wait approximately 10 seconds for the units to pair. Do not press any buttons during this process. - Step 4: Enjoy Your Video
