PTZ Balun

500007

Quick Installation Guide

Overview

The PTZ Balun allows CCTV video and “up-the-coax” Pan, Tilt, Zoom (PTZ) control
signals to be transmitted via a single unshielded twisted pair (UTP) cable for more
versatile cabling.

Used in pairs, the PTZ Balun allows CCTV security and surveillance equipment to be
integrated into structured cabling systems, enabling PTZ devices to be moved to any
convenient modular wall outlet. The PTZ Balun provides a versatile cabling solution for
CCTV security and surveillance by making use of standard UTP cabling techniques to
connect digital coax PTZ and video via a single unshielded twisted pair.

Installation

Troubleshooting

1. Power off equipment to be interconnected before installing the PTZ Baluns.

Note: The PTZ Balun has no user serviceable parts inside. Opening the

housing may damage the unit and void the warranty.

2. The PTZ Balun works in pairs.

3. Verify that the balun pin configuration corresponds to the pin configuration of your

modular outlets and plugs. The factory default is RJ45 pins 7 & 8 active.

4. The PTZ Balun standard connector is BNC-female. A coax cable with BNC-Male

comes with each balun for equipment with BNC-female.

5. Install one PTZ Balun at the PTZ controller near the camera. The PTZ Balun

comes with Velcro mounting pads. For maximum adhesion, ensure that mounting
surfaces are free of dust, oil, or other substances.

Note: Do not mount the unit on top of equipment ventilation openings.

6. Install the second PTZ Balun on the PTZ transmitter near the security center or

wiring distribution center.

7. Connect one end of the UTP connection to one PTZ Balun and the other end of the

UTP connection to the second PTZ Balun via RJ45 modular connectors, ensuring
that the pins match up on both ends. Remove any bridge taps from the line.

8. To avoid signal interference, keep CCTV equipment, baluns and cables away from

fluorescent lights, generators, motors, high voltage lines and other high frequency
signals.

9. Ensure that a twisted pair is used to transmit the signal. Do not split the twisted

pair.

10. Interconnect the baluns by connecting both ends of the same 4-pair UTP building

cable, which terminates to the RJ45 jacks of each balun. UTP patch cords may be
used if necessary.

11. Power on the PTZ transmitters and receivers and test the system according to the

equipment vendor’s instructions. The following diagram illustrates a typical
application.

If you experience problems with the PTZ Baluns, please follow the guidelines below:

 Ensure that the PTZ transmitter and receiver are functioning correctly.
 Replace the questionable balun(s) with known working units.
 Check all cables and connections and eliminate any split pairs or polarity problems.

The PTZ Balun is reverse polarity sensitive. Pin 7 must go to pin 7 and pin 8 to pin

8.

 Verify the quality of the UTP cable and the connections.
 Verify that distance limitations have not been exceeded.
 Verify that the equipment, baluns and cables are away from sources of EMI.
 If these steps fail to identify the source of your problem, please call an authorized

MuxLab Distributor or call MuxLab Technical Support at 1-877-689-5228.
