VGA balun
- Product Number : Passive VGA Balun
- Product : VGA Balun offers an ideal link between data output equipment and VGA monitors
DESCRIPTION :
Our passive VGA balun offers an ideal link between data output equipment and VGA monitors using 4-pair Category 5 shielded cabling, eliminating the cost and clutter associated with heavier VGA cables. With VGA balun at both the transmission and receiving ends of your setup you can enjoy an impressive transmission distance of up to 135 m (450 ft.) and a clear 640 X 480 pixel resolution.
Designed for use with computers, LCD monitors and multimedia projectors, the balun is perfect for classrooms, public presentations and video information systems. For better quality performance always use this product in conjunction with shielded cabling.
The VGA balun works in conjunction with laptops, PCs, CRT and flat-screen LCD monitors and multimedia projectors. Typical applications include corporate projection systems, classroom video instruction and video information systems.
