Overview

1.1. Description

The Active VGA/Audio Balun Kit allows VGA or component video, analog stereo audio and/or digital audio, one IR-emitter signal, and one RS232 signal to be transmitted via a cost-effective unshielded copper twisted cable in a point-to-point configuration.

The product supports remote power pass-thru and is DDC compliant with all “plug-and-play” laptops, PCs and displays. The product supports up to 1920 x 1200 pixels and 1080p resolution, and features manual gain adjustment and local monitor output for added versatility.

The product supports simultaneous stereo audio and digital audio transmission. The product provides IRemitter pass-through connectivity, supports up to 1080p resolution, and features manual brightness and sharpness adjustments.

The product converts the VGA signal from an unbalanced to balanced signal, and amplifies and equalizes the signal at the receiving end. It provides excellent image quality and minimizes distortions due to smearing, propagation delay, and phase deviation. The transmitter and receiver are shown on page 9.

Applications include digital signage, residential, boardroom, classroom, and home theater video systems.

3.3. Pre-Installation Checklist

There are two (2) components that must be verified before installation can begin: The transmitter and the receiver.

1. The transmitter is connected to the VGA video

source, usually a PC or Laptop computer, via VGA video & audio cables (not included).

2. The transmitter is connected to the receiver by a Cat

5e/6 (or higher) unshielded twisted pair cable (not included).

3. The receiver is connected to the display equipment,

usually a projector or screen, via VGA video & audio cables (not included).

4. Verify that the desired image resolution is within the

specifications of the Active VGA/Audio Balun Kit.

e 10

Pag

3.4. Installation Procedure

Verify that the distance between the Active VGA/Audio Balun 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 audio-video source

with the appropriate VGA video & audio cables.

2. If the Analog Audio (AA) interface is used (Stereo

3.5 mm), toggle the Audio switch to the “AA” position. If the Digital Audio (DA) interface is used (RCA), toggle the Audio switch to the “DA” position.

Figure 2: Position of the Audio Switch on the Transmitter

3. (Optional) Connect an infrared transmitter to the

3.5 mm connector.

4. (Optional) Connect the RS232 to the control source

with the appropriate DB9 to DB9 cables. Note: If the infrared 3.5 mm connector is plugged, the RS232 interface is disabled.

e 11

Pag

5. Connect a length of Cat 5e/6 (or higher) UTP cable

to the transmitter. Ensure that the wiring is in accordance with EIA-568A or EIA-568B standards and is straight-through.

Figure 3: Wiring Configuration

6. Connect the 12 VDC power supply to the

transmitter.

7. Plug the power supply into an AC power outlet. If

power is present, the green power LED will be ON.

e 12

Pag

To install the receiver, please follow the steps below:

8. Connect the Active VGA/Audio Balun receiver to

the display equipment with the appropriate VGA video & audio cables.

9. If the Analog Audio (AA) interface is used (Stereo

3.5 mm), toggle the Audio switch to the “AA” position. If the Digital Audio (DA) interface is used (RCA), toggle the Audio switch to the “DA” position.

Figure 4: Position of the Audio Switch on the receiver

10. (Optional) Connect an infrared receiver to the 3.5

mm connector.

11. (Optional) Connect the RS232 to the equipment with

the appropriate DB9 to DB9 cables. Note: If the infrared 3.5 mm connector is plugged, the RS232 interface is disabled. Set the RS232 interface as follows:

BAUD Rate: 9600 Data bits: 8 Stop bits: 1 Parity: None Flow control: Hardware

e 13

Pag

12. Connect the UTP cable to the Video IN/UTP

connector of the receiver.

13. Connect the second 12 VDC power supply to the

receiver.

14. Plug the power supply into an AC power outlet. If

power is present, the green power LED will be ON.

15. The brightness rotary switch adjusts the luminance

level to compensate for low frequency signal loss due to the Cat 5e/6 cable.

16. The sharpness potentiometer adjusts the equalization

to compensate for high frequency signal loss due to the Cat 5e/6 cable.

17. The skew (R G B potentiometers) adjust the delay

between the red, green, and blue colors to compensate for the delay differences due to the Cat 5e/6 cable.

18. To adjust the picture quality, rotate the brightness

rotary switch and/or sharpness and/or skew potentiometers on the rear panel of the Active VGA/Audio Balun receiver. The factory default position for the brightness (“Bright”) is “None,” and the factory default position for the sharpness (“Sharp”) and skew (R G B) is zero (rotated completely counterclockwise).

switch settings for adjusting picture brightness.

Adjustment

20. To adjust picture sharpness, begin with the

sharpness potentiometer (“Sharp”) rotated completely counterclockwise, and slowly rotate it in the clockwise direction until picture details become clear.

Note: For display equipment with automatic brightness control (for example, certain models of projectors), complete all installation procedures and ensure that the brightness rotary switch (“Bright”) is set to “None” and the sharpness potentiometer (“Sharp”) is rotated completely counterclockwise before turning the display equipment on. Otherwise, the display could override the brightness adjustment feature of the Active VGA/Audio Balun Kit.

e 15

Pag

21. After sharpness and brightness have been adjusted,

adjust the skew in order to align the red green and blue bars. To do this, open the electronic version of this manual and look at the skew correction pattern on the screen (see Figure 6). The R G B potentiometers adjust the red, green and blue colors horizontally. Using the potentiometer, move the three colored lines so they align perfectly. To move a color to the right of the screen, turn the corresponding potentiometer clockwise.
