The VGA+3.5mm Audio over Cat5 Box Transmitter, when used in conjunction with a receiver (29366 or 29368 - not included), allows you to extend a VGA signal over two Cat5/Cat5e/Cat6 unshielded twisted pair cables up to 300ft without signal degradation at 1920x1200 or 1920x1080 resolutions. This solution is compatible with any operating system and is truly plug and play with no drivers or software required. The transmitter and receiver come in either wall plate or box form factors and are interoperable allowing you to choose the form factors that are best suited for the application.

Built-In power surge protection and high ground loop immunity ensure high performance signal extension.
