Overview
1.1. Description
The VideoEase Active VGA Balun Kit allows VGA video equipment to be
connected via Category 5 twisted pair cable (UTP or STP) in a point-to-point
configuration. It is ideally suited to commercial and institutional users who need to
send high quality VGA in a PC-based multi-room application, including boardrooms
and training environments. It can easily connect a remote VGA source to a display
(for example, projectors or LCD, plasma, or CRT monitors). This product features
gain adjustment switches to optimize performance according to cable length, support
for local monitor connection, and a compact form factor.
The kit works by converting the VGA signal from an unbalanced signal to a balanced
signal and amplifying and equalizing the signal at the receiving end. It provides
excellent image quality and minimizes distortions due to smearing, propagation delay
and phase deviation. There are two components as shown in the photos below: the
transmitter and the receiver. Both components require an external 12 VDC power
supply (included).

jumper cable (not included).
2. The transmitter is connected to the receiver by Category 5 (or higher) UTP
cable (not included).
3. A monitor can be connected to the transmitter by a VGA jumper cable (not
included).
4. The receiver is connected to the display equipment, usually a projector or
screen, by a VGA jumper cable (not included).
5. The both transmitter and receiver must be powered by a 12 VDC external
power supplies (included).
6. Verify that the desired image resolution is supported by the VGA source and
VGA display.
3.4. Installation Procedure

MuxLab specifications (see Technical Specifications). In order to install the
transmitter, please follow the steps below:
1. Connect the transmitter to the video source with a VGA jumper cable.
2. Connect a length of Category 5 (or higher) UTP cable to the transmitter.
3. (Optional) Connect a local monitor to the transmitter with a VGA jumper cable.
4. Connect the 12 VDC power supply first to the transmitter and then plug the
power supply into an AC power outlet. If power is present, then the green
power LED will be ON.
To install the receiver, please follow the steps below:
5. Connect the receiver to the display equipment with a VGA jumper cable.
6. Connect the UTP cable to the Video IN/UTP connector of the receiver.
