This VGA extender transmits VGA and audio signals over CAT5e network cables over distances of up to 300 m when a high-quality, solid network cable is used. The extender system is easy to install and consists of a local sending unit and a remote receiving unit, which are connected with a CAT5e cable (not included); a high-quality, solid installation cable is recommended. The local sending unit connects to the VGA port of the computer system and features a VGA output for connecting a local monitor, while the receiving unit connects to the remote monitor or projector. The extender includes both gain and skew controls, allowing you to adjust the brightness and sharpness of the image to your liking. Both extender units are housed in a robust metal casing, making them ideal for use in factories and other industrial applications.
