The VGA extender SRN allows users to extend video signals far beyond the A/V rack. The VGA extender SRN can be used to extend an analog VGA signal to cover distances up to 150 feet. Industry standard category 5e (CAT-5e) cable is used for the extension. The VGA extender SRN sender unit connects to your computer using the supplied VGA cable. The SRN receiver connects to your monitor up to 150 feet away. One CAT-5 cable connects the sender and the receiver to each other, extending your video. The video transmitter and receiver boxes are small and unobtrusive, allowing installation in small spaces.
