Overview

1.1. Description

The Active CCTV Receiver Balun (Active Balun) allows CCTV video signals to be transmitted up to 1 mile (1.6 km) via a Category 5E/6 twisted pair cable when used in conjunction with MuxLab’s passive CCTV Balun (500000 or 500009) at the camera end. The Active Balun features Automatic Gain Control (AGC) and Ground Loop Blocking (GLB) for reliable and stable image quality. Once installed, no adjustments to the Active Balun are needed.

The Active Balun automatically adjusts the brightness, sharpness and color intensity of the video signal based on the actual cable conditions such as cable grade, distance, environmental effects on the cable, etc. Once installed, there is no further need to go on-site to check the video signal. Any further enhancements to the image may be made at the camera, monitor, multiplexer or DVR. The product requires a 24V, 2W AC power supply (not included) and connects directly to the video multiplexer or switcher. It features screw terminals with built-in strain relief for ease of installation.

Installation Procedure

3.1. Pre-Installation Checklist

Warning: Do not connect power supply to video signal or ground terminals. Unit can be damaged and warranty will be void.

The Active CCTV Receiver Balun is used to provide extended distance via a copper twisted pair. Before installing the product, please verify the following checklist to ensure that installation takes place smoothly.

1. The Active Balun is always connected to the

receiver side of a CCTV installation. For example, it is connected directly to the video input ports of the CCTV multiplexer, DVR or matrix switcher at the central monitoring location.

2. The Active Balun is used in conjunction with

MuxLab’s passive CCTV Balun (500009 or

500000). The passive CCTV Balun is connected at the CCTV source, which is usually the CCTV camera.

3. For best image quality and operator safety, the

multiplexer or DVR should be properly grounded. If this is not possible, then the Active CCTV Balun should be properly grounded. Please ensure that there is a building ground available. Note: If more

e 7

Pag

than one Active Balun is connected to the same multiplexer, only one balun needs to be properly grounded.

4. The Active Balun must be powered by a 24V, 2W

AC power supply (not supplied with the product).

5. The Active Balun is calibrated to work with CCTV

sources that conform to RS-343 (RS-170).

Pag

3.2. Installation Procedure

1. Connect the passive CCTV Balun (500000 or

500009) to the CCTV camera video output port.

2. Connect one twisted pair to the passive CCTV

Balun. If the balun is the 500009, use a small flathead screwdriver. If the balun is the 500000, crimp an RJ45 modular plug to the end of the cable, ensuring that Pins 7 & 8 of the RJ45 are connected to a twisted pair.

3. Identify the screw terminals on the Active Balun.

Warning: Do not connect power supply to video signal or ground terminals. Unit can be damaged and warranty will be void.

4. Ensure that the power is off on the CCTV

multiplexer or DVR. Connect the Active Balun to the appropriate video input port.

5. Connect the two power wires from the 24 VAC

supply. If power is present, then the green LED will be ON and dim. Multiple Active CCTV Baluns may be powered from the one 24 VAC power supply. Consult the power rating of the Active Balun in the Technical Specifications Section on page 6 to

e 9

Pag

determine how many units may be powered from one supply.

6. Using a small flat-head screwdriver, connect one

twisted pair for video. Please note that the baluns are polarity sensitive. Connect Ring (R) to Ring (R) and Tip (T) to Tip (T) as indicated by the label on each balun.

7. Power on the CCTV system. When a video signal is

detected, the green LED on the Active Balun will change from dim to bright.

8. Due to the Automatic Gain Control of the Active

Balun, the camera image may take a few seconds to stabilize. This is normal. The Active Balun automatically restores the video camera signal to its original quality, compensating for effects due to the presence of a UTP cable and electrical noise. Use the monitor’s standard controls to fine tune the final picture.

9. If there is visible low frequency background noise

(wood grain pattern) in the picture, connect the ground wire of the Active Balun to a true building ground.

10. If there is a severe ground loop problem in which the

voltage differential between the camera and the

e 10

Pag

Active Balun exceeds 1.5 VDC, the red LED will light up. If this occurs and there is image distortion, correct the problem by installing additional ground loop blocking equipment or eliminating the voltage differential. If there is no image distortion, the Active Balun will continue to function normally and there is no need to take corrective action.

11. The following diagram illustrates a typical

configuration.

12. The Active Balun is equipped with resettable fuses

to protect the circuitry. In the event of a power surge, the fuse(s) will trip and the green LED will dim. In order for the fuse(s) to reset, the power to the Active Balun must be turned OFF for 2-3 minutes. The fuse(s) will then reset and the power can be turned on again.

•Turn power off. Wait 2-3 minutes. Turn power on. Investigate cause of power surge.

•Check that wiring is not too close to transformers and lighting ballasts.

•Make sure that the wires on the signal pair are not reversed on one side.

•Check if the UTP pairs are correct (not split).

•Check DC loop resistance and verify if distance spec is exceeded.

•Reduce cable length or eliminate high-loss components

•Replace cable by one of higher grade.

•Connect ground of Active Balun to true building ground.

•Isolate remote camera power

entry and enclosure from local

ground.

•Ensure that camera is secured against static discharges (i.e., is

inside a metal, grounded cage).
