6. Diagnostics
6.1 OMNIScanner’s Diagnostic Functions
OMNIScanner has several advanced diagnostic test functions to help you with the
identification of network cabling faults. Diagnostics allows you to locate opens,
breaks, and short circuits as well as NEXT and Return Loss cabling faults quickly
and easily.
Press the (Diagnostics) function key to display the Diagnostics screen.
6.2 Wiremap
Wiremap identifies the location of opens, breaks, and pairs that are shorted. This
allows quick identification of the fault location.
Select Wiremap to display the WIREMAP screen. The screen displays the wire
connections between OMNIScanner and OMNIRemote. The pairs that are being
tested are defined by the selected test standard. Shield continuity is tested if a
shielded cable type is selected. (See Chapter 4, Setup for further information
about shielded cables.)
For each of the 8 conductors and the Shield, Wiremap can indicate proper pin
termination on each end, continuity to OMNIRemote, shorts between any two or
more conductors, crossed pairs, reversed pairs, split pairs, and any other miswiring.
For each pair, Wiremap displays the length. When a pair is faulty the length
indicates the distance to the fault.
