Fluke DSX-600 CableAnalyzer Troubleshooting Handbook page 10

If the cabling link fails to pass the wire map test - the test which verifies that all 8
wires connect the right pins at either end of the cable - the tester halts and presents a
window saying 'Warning Bad Wire Map". If you press OK, then the wire map diagram is
shown with the option to turn 'SCAN ON' which may help find intermittent connection,
or 'FIX LATER' which enables you to save the results then go to then next link to be
tested. Alternatively, you can 'CONTINUE' which continues the test with the bad wire
map, this may allow you to find other issues to help you troubleshoot the problem in the
link. Figure 4 shows such a wire map failure. The DSX-600 main unit is always assumed
at the left hand side of these screens, i.e. the near end. The wire map diagram shows
Wire 6 of pair 3/6 and Wire 7 of pair 7/8, both are open at 1.4 Meters at the near end
and 4.7 Meters from the far end. The software halts and asks the operator whether or
not to continue the test. It often makes more sense to tackle the wire map error before
continuing the test. The open wire causes the results for some test parameters to fail. In
this case we continued and the DSX shows a FAIL. At this point we could inspect the link
at 1.4M from the near end to discover the cause of the failure. We could also select the
DIAGNOSTICS tab which enables us to see the results of the HDTDR or HDTDX results.

Figure 4
Shows a wire map failure on wires 6
and 7. Both are open at 1.4 m from
the near end and 4.7 m from the
far end, suggesting the cable has
been severed or not connected at
the same points. Inspect the link at
these points to identify the issue.
