The VGA Balun eliminates costly and bulky VGA cable, allowing a VGA source to be connected to a VGA monitor via 4-pair Cat5e/6 twisted pair cable. In order to ensure a commons signal ground, shielded twisted pair is highly recommended.Used in pairs, the VGA Balun allows VGA video to be transmitted up to 350ft (107m) via Cat5e/6 at 800 x 600 resolution. Each VGA connection requires a VGA Balun at the source (500010) and a VGA Balun (500011 or 500014) at the display. The VGA Balun works in conjunction with PCs, laptops, plasma, LCD monitors and DLP projectors.
