The Gefen VGA Extender SRN is a distribution system that allows you to extend VGA signals by transporting them over CAT-5 Ethernet cable. The system consists of a transmitter that connects to your VGA source, which transports the signal over CAT-5 cable. The receiver then accepts this signal and translates to its original format for output. This unit supports transmission distances of up to 150'. Resolutions up to 1080p or 1920 x 1200 are also supported.
