CCTV Power-Thru Converter Balun (500024-CNV)

Quick Installation Guide

Introduction

The CCTV Power-Thru Converter Balun (500024-CNV) allows video and remote
power to be transmitted via one 4-pair Cat 5e/6 cable, thus eliminating the need to
install multiple cables for more efficient cabling in the analog CCTV security and
surveillance environment. Furthermore the product converts 24VAC to 12VDC @
400mA to allow 12VDC cameras to be remotely powered from a central 24VAC
CCTV power supply. The CCTV Power-Thru Converter Balun works in
conjunction with MuxLab’s CCTV Power-Thru Balun (500024), Passive CCTV
Power Integrator Hub (500136), Passive CCTV Hub (500130) and LongReach II
Active Balun (500124) and Hub (500126, 500127) for a complete cabling solution.

Installation

Pre-Installation Checklist:

Note: For regulatory reasons, use of a Class II power supply is
recommended and may be required with the use of this product in some
regions.

1. The CCTV Power-Thru Converter Balun (500024-CNV) is designed to be

installed at the camera side.

2. Ensure the CCTV equipment and remote power supply is turned off.

3. One (1) twisted pair is required for the camera video signal. Three (3) twisted
pairs are required for remote power.

4. Verify that the cable length is within MuxLab specifications. The
maximum distance for 24VAC and remote power is 795 ft. (242m) at the
maximum allowable power consumption of 400mA.

5. Identify the pin configuration of the balun by checking the product label or the
specification section of this installation guide.

Installation:

1. At the camera side, connect the coaxial cable lead of the 500024-CNV into the
BNC-F connector of the CCTV camera.

2. At the camera side, connect the balun’s red and black wires to the 12VDC
power input terminals of the camera.

3. Connect a 4-pair Cat5e/6 cable to the balun. The cable must be terminated
straight-through with an RJ45 modular plug according to either the EIA 568A
or 568B wiring standard. Cross-connection hardware such as wall outlets and
patch panels may be used as required.

4. Note: The CCTV Power-Thru Converter Balun is reverse polarity

sensitive. When connecting the baluns, ensure that “Ring [R]” is
connected to “Ring [R]” and “Tip [T]” is connected to “Tip [T]”. Verify
that there are no split pairs or crossed wires.

5. At the head end (DVR or IP encoder), repeat steps 1 to 3 for the receiver side
balun or hub (i.e. 500024, 500130, 500124, 500126, 500127, 500136).

6. Power-on the CCTV equipment and central CCTV power supply. Verify
image quality.

7. The following diagrams show typical configurations using the 500024-CNV.
