condition in the above descending order before
detecting other fault conditions. The detection and
indication of the presence of a fault is handled on a
“one-per-test” basis. Once a fault is corrected, it is
recommended the cable be tested again for other
faults.
OPEN There is no “OPEN” indication. A typical
cable may have 2, 3, or 4 pairs. OPENS are
displayed as an unlit symbol. The user will
determine if a pair is present and continuous or
OPEN by comparing the illuminated symbol to the
expected number of pairs that should be good.
SHO. A short circuit condition exists (see Fig.1).
MIS. Indicates the improper assignment of
individual wire pairs to pins for the wiring schemes
tested (see Fig.2).
REV. Reverse wiring means the pin for one wire
in a pair is connected to the opposite pin for the
pair in the remote jack (see Fig.3).
SPL. Split pairs occur when the tip (positive
conductor) and ring (negative conductor) of two
twisted pairs are interchanged (see Fig.4).
