VGA Balun
(500010, 500011 & 500014)
Quick Installation Guide
Overview
The VGA Balun allows VGA video signals to be transmitted up to 450ft (132m) via 4-pair Cat
5 twisted pair cable for more cost-effective and more versatile cabling. Used in pairs, the VGA
Balun eliminates costly and bulky VGA cable, allowing VGA monitors to be connected at
extended distances from the PC via standard Cat 5 twisted pair cable. Used in pairs, one VGA
Balun (500010) connects to the VGA source (ie; output) and one VGA Balun (500011 or
500014) connects to the VGA destination (ie; 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.
Note:
CAT5E/6 SHIELDED TWISTED PAIR CABLE (STP) IS REQUIRED
In case Cat5e/6 unshielded twisted pair cable (UTP) is used, please order instead:
VGA Balun II: 500040/41/42/43
VGA Balun II Kit: 500040-42-PK
VGA Wall Balun II: 500041-WP-US/43-WP-US/41-WP-UK/43-WP-UK
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.
Installation
To install the VGA Balun, perform the following steps:
Caution: Do not attempt to open the housing. There are no user-serviceable parts inside
the VGA Balun. Opening the unit will void your warranty.
1. 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.
2. Since the VGA Balun does not support VGA handshaking and control signals 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 (ie; resolution, color, etc). Also, in order to achieve optimum results via
twisted pair, set the Contrast and Brightness levels to maximum.
