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:
