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).

3.3. Pre-Installation Checklist

There are two components: the transmitter and the receiver.

1. The transmitter is connected to the video source, usually a PC, by a VGA

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

Verify that the distance between the VGA transmitter and receiver are within

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.

7. Connect the 12 VDC power supply first to the receiver and then plug the power

supply into an AC power outlet. If power is present, then the green power LED

will be ON.

8. To adjust the picture quality, toggle the gain adjustment DIP switches on the rear

panel of the receiver. The factory default position is “all OFF” (up position).
