VGA Extender   

Model: VB100VK

The VGA Extender allows VGA video signals to be transmitted up to 500ft / 135m via 4-pairs CAT5 

STP or UTP cable. Used in pairs, the VGA Extender can be used in home or commercial applications 

as a smart, fast and cost-effective solution. It eliminates costly and bulky VGA cable, allowing VGA 

monitors to be connected extended distances from the PC via standard twisted pair cable. This 

product is ideal for classrooms, lecture halls, retail kiosks, video information displays, overhead 

projector systems, PC-training systems, and tradeshows PC demo systems.
