Connections:
1.
At the camera side, connect the balun’s coaxial cable lead into the BNC-F
connector of the CCTV camera.
2.
At the camera side, connect the balun’s red and black wires to the power input
of the camera.
3.
If the 500024 is being used, connect a 4-pair unshielded twisted pair cable to
the balun. The cable must be terminated with an RJ45 modular plug. Cross-
connection hardware such as wall outlets and patch panels may be used as
required. The 500024 supports TIA 568A and 568B wiring standards.
4.
If the 500029 is being used, connect one (1) twisted pair to the “R/T” terminals
for video. Connect three (3) twisted pairs to the “+/-“ terminals for remote
power , by connecting one wire from each twisted pair to each terminal. See
diagram below.
5.
Note: The CCTV Power-Thru 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.
6.
At the receiver side (i.e.; DVR side), repeat steps 1 to 4 for the second balun.
7.
Power-on the CCTV equipment and remote power supply. Verify image
quality.
8.
The following diagram shows a typical configuration using the 500024.
Troubleshooting
The following table describes some of the symptoms, probable causes and
possible solutions regarding the CCTV Power-Thru 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.
