The Hall Research UV1-S is a Mini-Cat VGA Over CAT5 Sender. The sender converts a PC's VGA signal into a format that can be transmitted using a single inexpensive and commonly available Category-5 Unshielded Twisted Pair (UTP) cable with RJ45 connectors. The Cat5 signal is converted at the receiver back to VGA for connection to your monitor, projector or other display device. The UV1 can extend HD video up to 500 feet (150 meters) with little to no degradation of video quality.
The sender and receiver are each housed in a small plastic enclosure. Included with the pair of devices are: one small power adapter (can be powered at either end), and a short adapter cable for easy connection to the standard HD-15 connector of the PC.
