8 Port VGA Video Extender over Cat 5
Product ID: ST1218T
The ST1218T 8 Port VGA Video Extender over Cat 5 is designed for use with our ST121 VGA over Cat 5
extension series, offering convenient VGA video distribution at distances of up to 492 feet (150 meters)
using standard Cat 5 (or better) cabling.
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.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
