Universal Tester RJ12, RJ45, USB, BNC
This simple device is primarily used to check the correct wiring pairs (the Wire Map) Data cable for structured cabling components.
What is Wire Map (map diagram)?
This parameter controls the accuracy of the involvement of the individual pairs of outlet or patch panel, including linking the shield of STP cabling. It also checks the signal along the length of the cable - ie it is able to break one of the wires or. their fault. Wire Map parameter is very important, but by itself can not ensure correct functionality of the installed network. To measure the accuracy of maps involvement is sufficient and very simple measuring device.
What to do if the Wire Map parameter fails?
First, it is necessary to check the accuracy of the individual wires in the terminal. If the wiring is correct - that corresponds to the standardized schemes T568A or T568B and Wire Map still fails, there may be several causes: an incorrectly wire the terminal block inside the cable break or short circuit. Advanced testing devices are able to measure with relatively high accuracy the location of the fault, thus simplifying correct the problem.
