The ST1212T 2-Port VGA over Cat 5 Extender is designed for use with our ST121 VGA over Cat 5 extension series, offering convenient video distribution at distances of up to 500 feet (150 meters) using standard Cat 5 (or better) Ethernet cabling. Comprised of the transmitter unit only, the ST1212T 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 & receiver by an additional 500 feet (150 meters), for a total extension distance of 1000 feet (300 meters). Similarly, up to 3 repeater units can be used between transmitter & receiver, enabling you to connect monitors at each repeater, while still extending the total distance. Backed by a Star Tech.com 2-year warranty & free lifetime technical support. Cat 5 extension enables you to make use of existing Ethernet infrastructure wiring to extend VGA video. A pure hardware design provides an easy installation & setup, with no software or drivers required. Support for cascading multiple transmitter units, & the use of repeaters for additional distance, providing a scalable system for VGA distribution. Use a combination of repeaters or receivers, to simplify adding more displays to your digital signage installation. Position displays where they will be most effective for viewing, but install the system equipment elsewhere in a clean & secure environment. Ideal for digital signage applications in financial, educational & corporate sectors, to deliver up to date, eye-catching content. Expand the range of your advertisements in auditoriums, trade-shows & retail environments.
