Examples of Common Results
Simple RJ11 Telephone Cord
This screen shot shows how a simple RJ11 to
RJ11 connection lead is tested. As the plugs are
connected the “same way up” either end of the
cable, there is effectively a polarity reversal. And
as only a single pair is connected, the other pairs
(2/5 and 1/6) are open.
CAT5 Crossover Cable
This screen shot shows how a typical two-
pair crossover cable is often used to connect
devices back to back, with the pairs 1/2 and 3/6
swapped. This is still shown as a “Miswire” as
the only condition to allow the “Pass” icon to be
set is a perfect straight through cable. As there
are several different types of crossover cable
currently in use, it was decided to show the con -
dition and allow the user to decide if the result is
what you require in your specific application.
