The next section describes each test, including how to set test limits, how to read results screen and how to troubleshoot test results.

Wire Map

Wire Map easily diagnoses your communications link for crossed pairs, shorts, split pairs and opens.

Crossed pairs occur when two or more wires are reversed from end to end, thus resulting in a communication failure.

Split pairs occur when physical continuity is maintained but wires from logical pairs are split up. This error is more difficult to detect because there is still a pin-to-pin correspondence. Wire Map finds split pairs, and you can also suspect split pairs if the cable’s NEXT test result is less than 22 dB. For more information, refer to Microtest’s Category 5 Cable Testing Handbook.

Wire Map Test Results

To display this screen, press View (F1) from the AUTOTEST RESULTS screen, then press the

key until the WIRE MAP TEST RESULTS screen is displayed.

The wire map screen displays a graphical representation of the wiring in your cable. Near end wiring displays on the left side of the screen and far end wiring displays on the right side of the screen.

A >< between wire pairs indicates a crossed pair.

No line between wire pairs indicates an open.

A ] between wire pairs indicates a short.

A straight line between pairs indicates a good pair.

“PASS” or “FAIL” indicates if wiring is correct or incorrect.

Press Splits (F1) to display the SPLIT PAIRS screen, with the split status displayed to the right of the wire pair.

Press the arrow key to display the next test result screen or press the ESCAPE key to exit. Note: You can also generate a wire map by attaching the Injector to the far end of the twisted pair cable and pressing the Find Cable Faults key.
