Muxlab PTZ Balun - Manual (Page 2)

Installation
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.
Troubleshooting
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.
