After you have learned a good cable and measured a test cable,
summaries of both will appear. Start
1 +
| - If there are no
differences, you will see a green checkmark just above the "Print"
button in the Test Data summary box. In the example shown below,
however, the cables do not match and a red "X" appears
instead.
What can you tell about the differences between these two cable
using just the information in the summary boxes?
2 + | - Click on the "triangle" button (Greek letter Delta) to see a detailed list of all wiring differences (shown below).
3 +
| - In the
left column, a "+" indicates an extra connection (a
short), while a "" indicates a missing connection
(an open). In this case, we see a miswire between pins 7 on the
left and 15 on the right, and that the shield is missing.
4 + | - Look at the Test Data wiring to visualize the problems.
5 +
| - For batch
testing of cables, this entire process may be automated by using
a Macro (described in an upcoming topic Batch Testing of Cables).
In that case, you would press the TEST pushbutton once on the
test fixture and read the PASS/FAIL result on LED lamps.
