It’s ensuring that pin 1 is wired to pin 1 and 2 to 2, 3 are together, 4, 5 etc. Next we’ll push the button and it goes out and it tests the cable. We will plug the ends into the tester (we already know this is a good cable) but we always want to make sure we test our cable tester with a known good to make sure that we are using good cables. It also shows us the actual T568‑A and the 568‑B, the actual way the cable should be wired. It’s going to show us whether or not we’re wired correctly. You’ll notice on the blue one, we’ve got a series of cables here and it’s got lights. The first one we are going to look at is this blue LinkMaster. You can pick these up at most of your computer shops anywhere you go. These simple cable testers are inexpensive. Let’s take a look at a simple cable tester. It also allows us to check connectivity from one end to the other end.

One of the things we can look at is are we properly wired using this cable tester. Since you may find yourself creating your own cables such as installing our own RJ45 or BNCs ends, we want to make sure those cables have been correctly wired. We have previously covers cables and connectors so now let’s look at some tools that we can use to test our different cables in our environment. In this post, CompTIA Network + instructor Rick Trader demonstrates common cable tester and how to use them in network configurations.
