connection from one wire of the pair to the
other wire of the pair or to any other wire in
the cable or the shield. A short is indicated
by the Short icon being on and flashing -’s in
the appropriate pin positions on the second
line for the pin numbers involved in the
shorts plus a flashing S icon if the shield is
shorted to a pin.
Miswire
- A wire or both wires of a pair
are not connected to the correct pins at the
other end of the cable. The wire map shows
the pin numbers from line (main) to line
(remote). A reverse pair is a special case
of a miswire in which the pair is wired to the
correct pair of pins or to another designated
pair of pins, but the two leads are reversed.
The Testifier™ is able to test for split pair
errors as long as the wiring errors are in
pairs. The Fail icon and the pin numbers,
which are miswired, will be flashing.
Split Pair
- A split pair is an error in the
twisting of the wires together within the
cable. The cables generally are made up
of eight wires twisted together in pairs.
These pairs are designated as pairs by the
wiring standards and are intended to carry
a signal and its return. &, &6, &5 and
&8 are the pairs designated by T568A/B for
a RJ5 jack or plug. A cable can be wired
