WIREMAP TEST SCREEN
If more detail is required about the Wiremap Test, the Wiremap screen can be displayed
by highlighting the Wiremap Test icon on the HOME screen and pressing Enter.
Summary
Shows the status or result of the test. In this example, pins 1 and 2 are reversed,
resulting in a miswire fault. Ethernet is tolerant of such a fault, so the Data Test will pass
in this case. That is why it is important to perform both the data test and the wiremap
test to prove that the cable meets all of the required quality standards.

A split pair is a wiring error in which each pin is connected to the correct pin at the other end of
the cable, but the pairs of pins are connected using wires from different twisted pairs. Split pairs
can cause crosstalk and data failures, but are not reported as faults by simple wiremappers. The
advanced wiremapper in SignalTEK CT can detect split pairs that some other wiremappers can
not detect. Split pairs can start with a simple wiring error. In the example below, pins 3 and 4 are
reversed at one end of the cable:

If the error is repaired at end of the cable where the fault is located, the fault is removed:

If the error is repaired at the wrong end of the cable, the end-to-end continuity is
corrected, but a split pair is formed:

This cable may cause Ethernet data errors, and if so it will fail the SignalTEK CT Data Test.
