Exposing Individual Twisted Pairs
There is no single method when exposing the four individual pairs in twisted pair
cabling; however, it does help to have a cable stripping tool designed to strip the cable
jacket/insulation.
Begin by stripping back the cable’s outer jacket/insulation about an inch (or more
depending on whether multiple baluns will be connected to the pairs of a single cable)
so that the internal wires are exposed. Be careful not to cut the internal wires when
stripping the insulation/jacket. Eight twisted wires and a string should now be visible;
the string is unnecessary and may be removed. These eight wires, which when
combined form four pairs, connect directly to the 110 punch-down connector on the rear
of the balun.
Troubleshooting
If your equipment malfunctions with AVO-A4-WP110-EU baluns in place, follow
the troubleshooting procedures below:
1.
Perform diagnostics on source and destination equipment following the
manufacturer’s instructions.
2.
Check all connections and the twisted pair cabling system.
3.
Verify the 110 punch pattern conforms to EIA 568B.
4.
Verify the maximum recommended cable distances have not been exceeded.
5.
Verify that the twisted pair cable does not run parallel to any power cables.
6.
Verify no sources of high EMF interference, such as fluorescent lights or
motors are in the vicinity.
7.
Verify both the source and destination equipment are grounded on the same
ground plain. Verify both have three-prong power connectors.
8.
Replace the balun with another balun that is known to be operational.
