VGA Balun II

500040, 500041, 500042, 500043

© MuxLab Inc. 2006-2013 VGA Balun II

Overview

The VGA Balun II eliminates costly and bulky VGA cable,
allowing a VGA source to be connected to a VGA monitor via
one (1) 4-pair Cat5E/6 unshielded twisted pair (UTP) cable.
Used in pairs, the VGA Balun II allows VGA video to be
transmitted up to 350ft (107m) via Cat5E/6 at 800 x 600
resolution.

Each VGA connection requires p/n 500040 or 500043 at the
source and either p/n 500041 or 500042 at the display. 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. The product features a “reset” button that
may be required when used in conjunction with certain sync-
sensitive displays.

The VGA Balun II does not support VGA handshaking and control signals. Therefore it is
necessary to set the monitor attributes prior to installing the VGA baluns. In order to do this,
first connect the standard VGA cable directly from the PC to the monitor and then set the
monitor attributes to the required settings (i.e., resolution, color, etc.). Also, in order to
achieve optimum results via twisted pair, set the contrast and brightness levels to maximum.
