Quick Installation Guide
Overview
The VGA Balun allows VGA video signals to be transmitted up to 450 ft (137 m) via a 4-pair Cat
5E/6 twisted pair cable for more cost-effective and versatile cabling. Used in pairs, the VGA Balun
eliminates costly and bulky VGA cables, enabling VGA monitors to be connected at extended
distances from the PC via standard Cat 5E/6 twisted pair cable. Used in pairs, one VGA Balun
(500010) connects to the VGA source (i.e. output) and one VGA Balun (500011 or 500014)
connects to the VGA destination (i.e. monitor input). The VGA Balun transmits the RGB video,
horizontal and vertical synchronization pulses. Since the VGA Balun is a passive device and uses
only 8 wires, it does not support VGA handshaking/control signals.
In order to ensure reliable signal continuity between the equipment, it is recommended to use
shielded twisted pair (STP) cable terminated with shielded RJ45 connectors.
Applications
The VGA Balun allows pre-existing twisted pair cable to be used in such applications as classroom
video distribution, overhead projector systems, PC-training systems, and tradeshow PC-demo
systems.
