Preparing to Test ControlNet Trunk Cables
6.1.1
Before you begin
Two tests are covered here:
l
Testing using an Ohmmeter, and
l
Testing using a Time Domain Reflectometer (TDR).
6.1.2
When to use these tests
These tests have two primary uses:
l
after building ControlNet trunk cable segments from certified raw cable, or
l
when troubleshooting your ControlNet network and a cable segment is determined to be suspect.
6.2
Testing using an Ohmmeter
This procedure is used to test completed sections of trunk cable for electrical shorts and continuity. It is
identical to the procedure performed after cutting and stripping raw cable lengths, except that the
connectors have now been attached.
