VideoEase CCTV Pass-Thru Balun (500022)

Quick Installation Guide

Introduction

The VideoEase CCTV Pass-Thru Balun (500022) allows video, remote power and
2-wire pan, tilt, zoom (PTZ) control signals to be transmitted via one 4-pair Cat 5
cable, thus eliminating the need to install multiple cables for more efficient cabling.

The Pass-Thru Balun may be used in pairs or it may be installed at the camera and
connected to standard twisted pair cross connect devices at the remote end. The
product is fully compatible with other MuxLab CCTV baluns such as the 500000,
500009, 500023 and 500015.

Installation

The CCTV Pass-Thru Balun supports connectivity for video, remote power and control

via one four-pair twisted pair cable. It is not mandatory that all signals be present. One
or more of these signals may be present. To install the VideoEase CCTV Pass-Thru
Balun at the camera, perform the following steps:

Connect Video:

1. Identify the pin configuration of the CCTV Pass-Thru Balun. One twisted pair

is required for each camera video signal. Note: The CCTV Balun is reverse
polarity sensitive. Please ensure that “Ring” is connected to “Ring” and “Tip”
is connected to “Tip”.

2. Plug the Pass-Thru Balun into the BNC connector of the CCTV camera

Connect PTZ Control (optional):

3. If pan,tilt, zoom (PTZ) control signals (i.e.; RS422) are being sent to the

camera, first ensure that PTZ controls are turned off before making any
connections.

4.

Connect the Blue/White-Blue wires to the control input of the camera. Please
ensure straight-through polarity between the CCTV camera and the remote
control device.

Remote Low Voltage Power (optional):

5. If remote low voltage power is being sent to the camera, first ensure that the

power supply is off before making any connections.

6. Connect the red and black wires to the power input of the camera. Please

ensure straight-through polarity between the CCTV camera and the remote
control device. Remote power is transmitted via two twisted pairs up to the
camera. MuxLab provides a guideline for maximum distance based on camera
power requirement as stated in the specification section. Please consult the
CCTV equipment manufacturer for more detailed performance specifications.

7. Complete the connection between the two baluns, using straight-through 4-pair

unshielded twisted pair cable and cross-connect blocks as required. The
CCTV Balun is reverse polarity sensitive. Please ensure that straight-through
wiring is maintained.

8. At the remote end, the video, power and control signals are ungrouped

following the specified pair assignment and respecting the signal polarity. The
following diagram shows a typical configuration.

Symptom Probable Causes Possible Solutions

Poor picture quality,
distortion, interference

1. EMI interference. Check that wiring is not too close

to transformers and ballasts.

2. Wires reversed on signal

pair on one side

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

3. Split pair Check if the UTP pairs are split

and correct. Each signal pair
must be twisted.

Symptom (cont’d) Probable Causes Possible Solutions

No video image 1. Power-off. Check power supplies of CCTV

equipment.

2. Wrong pin configuration Check pin configuration and

verify straight-through wiring.

3. Defective CCTV Balun Change CCTV baluns for another

pair.

Picture faded or weak 1. Exceeded distance

specifications

Check DC loop resistance and
verify if distance spec is
exceeded. Reduce cable length or
eliminate high-loss components.

2. Lower grade UTP cable is

introducing high signal
losses.

Use signal repeater for extended
distance or replace cable by
higher grade.

No power at camera 1. Wrong pin config. Check wiring

2. Distance exceeded Move power closer to camera.

PTZ controls not

1. Wrong pin config Check wiring.

9. Power-on the CCTV equipment and check the picture quality. The video

should be clear and sharp within the maximum specified distances.
