HDMI Over Dual Cat5 Extender Wallplate Kit is the perfect solution for those who need to extend a HDMI signal over a long distance over two Cat5/6 cables. Simply run two Cat5/6 cables between the local transmitter and remote receiver wallplates, and plug in standard Tripp Lite HDMI cables to the HDMI source and the display. The Green LED on the remote receiver wallplate lets you know that power from the source and monitor. When functioning properly, only the Green LED will be lit. If the Red LED is illuminated, it means that the remote receiver is not receiving a functional signal from the source.
