The UV1 is a single channel UTP (CAT5) VGA video extender consisting of a sender (UV1-S) and a receiver (UV1-R) sold together as a pair. 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, which is used in most Local Area Networks. At the receiving (remote) end the Cat5 signal is converted back to VGA for connection to your monitor, projector or other display device. The sender and receiver are each housed in a small plastic enclosure and include a HD15 video connector and a RJ45 connector for the Cat-5 cable. 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.
