These baluns eliminates costly and bulky VGA cable, allowing a VGA source to be connected to a VGA monitor via one (1) 4-pair Cat 5 unshielded twisted pair (UTP) cable. Used in pairs, the VGA Baluns allow VGA video to be transmitted up to 350ft (107m) via Cat 5 at 800 x 600 resolution. Each VGA connection requires p/n MU-500040 at the source and either p/n MU-500041 or MU-500042 at the display. The product features a "reset" button that may be required when using certain displays. More information may be found in the product Installation Guide. The VGA Balun II works in conjunction with laptops, PCs, plasmas, CRT, LCD monitors and DLP projectors. Typical applications include digital signage, boardroom systems, classroom video instruction and custom audio-video systems.
