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

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).
