Extend and distribute a VGA signal to up to 8 displays over Cat5 cable.

Comprised of the transmitter unit only, the ST1218T requires one Receiver Unit (ST121R) per display that you are connecting. For added versatility, the VGA over Cat 5 Repeater (ST121EXT) can be used to extend the distance between the transmitter and receiver by an additional 492-feet (150 meters), for a total distance of 984-feet (300 meters). Similarly, up to 3 repeater units can be used between transmitter and receiver, enabling you to connect monitors at each repeater, while still extending the total distance.
