DataShark Network Cable Tester - Cable Mapper, Check Continuity - Test Patch Cords or Installed Cable Runs

Bought this to test Cat5 connectors on a whole-house stereo installation. Ive left it to chance before and had a couple of bad connectors that resulted in unreliable operation of the keypads. This takes the guess work out of the project - you might be surprised how many of the male Cat5 connectors are bad - I had to replace 3 of 24 which would have resulted in headaches down the road when access was much more difficult. I also discovered a damaged length of Cat5 cable that must have been crushed and was causing intermittent shorts. For the small investment, this is a fantastic tool.

Works great! Helped me find the bad crimp and fix it without having to mess around with something that looks like I should be finding ghost with.Thank you!

This target has saved me some time and trouble. I made a few cat 5e cables and used this to test them. Of course I mucks up one of the cables and this saved me the time of using the cable and then ending up troubleshooting.

Great for running network cables through my house.

This RJ45 Network Cable Tester kit is essential if you need to make your own patch cables for connecting a home or business network. It is a must to the technicians networking tookkit. The Tester was used to determine if all conncetions were made correctly and or just how many of the wire connections you had right. If all the wires are not corrected in the same order on each end ot the patch cable, you will not have a successful connection. A good product and at a good price. Thanks DataShark for a tester that is practical, useful, and enconomical.

This tester works great for the money. I tried to test my Cat 5e runs with a laptop and my router, but I had enough issues with the connectors that I needed one of these to figure out what I had done wrong. I had a couple of connectors that I cut the wires too short to get a connection and a couple where I did not get the wires inserted in the right order. You really dont need more than this to verify data runs. Save the money versus the more expensive testers and use a multimeter to test your Coax runs. You can test Coax by checking continuity (or resistance) for a open circuit between the center wire and the outer wire on one end. Then short the other end (an alligator clip works) and test for continuity. You dont need any special adaptors to test coax with a multimeter.

Very nice. Works just how I wanted and in the correct price point. I use it every once in a while but it helps to keep from asking a friend if I can use his. Great investment for cable making.

Awesome product. Traced my wires quickly and cheaper than having it come out. Great product for the diy’er

I would like to have a test channel for the shield but it does the critical test on the 8 active wires just fine.

This is the go to tune for testing your Internet connections it is simple to use and very accurate
