All you have to do is simply plug the Networx® RJ45 loopback tester into the jack that you want to test or the one you are suspicious about.
#Loopback tester rj45 portable#
It looks like a simple plug at first glance but the compact, rugged design makes it highly portable and usable in the tightest corners. An RJ45 Loopback Tester is an exceedingly user friendly cable tester.
