Product Information：



Overview
The VGA Balun eliminates costly, 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. The VGA Balun works in conjunction with PCs, laptops, plasma, LCD monitors and DLP projectors.

Applications

Boardroom systems, classroom projection systems digital signage, custom residential AV, DVR monitor extension, medical display systems

Quick Setup Guide

Plug your VGA cable coming from your PC into the Transmit Baluns HD15 connector. Secure the cables using the lock down screws. Make a similar connection between the Receive Baluns HD15 connector and your display. Insert the CAT5 cable into both ends of the Baluns. You may use standard EIA 568A/B termination
