Wiring and Display Examples for Data Cable

Pass appears on the display indicating
a properly wired cable. The pin numbers
on the top row and bottom row are the
same indicating proper continuity.
The pairs cross over (transmit to
receive and receive to transmit).
Pass and X will appear on the display
and the pin numbers on the bottom row
indicate the corresponding cross over
to the pin numbers on the top row.
There is a split between the pairs on
pins 3, 4 and 5, 6. Fail and Split appear
on the display and the pin numbers
with the
split will flash indicating whic
h
pairs are split.
Note: The T568A wiring standard is the
same as T568B, except that T568A swaps
the green and orange pairs. Either standard
will test the same electrically, as long as the
same standard is used on both ends of the
cable.

T568B Data Cable With Split Pairs
Pins 1 and 2 are shorted and the pair
on pins 7 and 8 is open. Fail, Short
and Open appear on the display
and the pins with wiring errors will
flash.
Dash lines will appear below
the shorted pins and a blank space
will appear below the open pair.
The pair on pins 1 and 2 is reversed
and the wires on pins 5 and 6 are
crossed at one end of the cable.
Fail and Miswire will appear on the
display and the pins with wiring
errors
will flash. Pin
s 2 and 1 shown
below pins 1 and 2 indicate a reversal
on the Orange pair. Pins 6 and 5 shown
below 5 and 6 indicate a crossed
connection.
