The ST128UTPE 8 Port VGA Video Extender over Cat 5 (UTPE Series) allows up to 9 (1 local & 8 remote) monitors to be connected to a single VGA source. The video signal is carried to the remote monitors over standard 4 pair Category 5 & Category 6 UTP cable using RJ45 connectors & supports distances of up to 300m / 950ft. At each remote monitor an STUTPRXL receiver (see accessories) is required. The receiver unit converts the signal from the UTP cable back into VGA video for the monitor. Backed by a Star Tech.com 2-year warranty & free lifetime technical support. Works with the STUTPRXL receiver, or the STUTPRXWAL (wall-plate receiver) for flexibility in your setup. Extends the connection distance of VGA displays by up to 950 feet (300 meters) offering flexibility in the placement of your equipment. Cat 5 extension design means that you can make use of existing Cat 5 or better wiring infrastructure.
