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.
Troubleshooting
The following table describes some of the symptoms, probable causes and
possible solutions regarding the CCTV Power-Thru Converter Balun. If you
still cannot diagnose the problem, please call MuxLab Technical Support at
514-905-0588.
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.
No video image
1. Power-off.
Check power supplies of CCTV
equipment. Check power supply
fuse.
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 or
intermittent power
at camera
1. Wrong pin config.
Check wiring
2. Distance exceeded
Verify distance specifications for
remote power. Move power closer
to camera.
