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

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.

The DataShark RJ45 Network Tester (70025) is an incredibly simple but essential tool. You can quickly and easily test everything from short patch cables to long through-the-wall data runs. This tester continuously pulses each of the 8 wires in succession and successively illuminates each of the 8 LEDs one at a time on both the sender end and the remote units. If there is a bad connection, the LED will not illuminate on the remote unit identifying the bad wire. If there is a cross wiring problem, the LEDs on the remote unit will illuminate out of succession so you can tell which wires are crossed. This makes it very easy to identify and fix any wiring problems.

Great for running network cables through my house.

Its simple and works really well. Tells you which lines are not terminated properly. Great product especially for the price.

Cheap, reliable, does the job, what else can you ask for?

worked just fine, found error I had made quickly. Worked on a cable + - 300 long. 4 stars because Im sure it had a fault I just didnt detect.

Does exactly what I needed, simple to use and the price is right. My house is wired with cat5e to most rooms and but the switch in the bell atlantic box was acting up. I needed something to be able to check connections and locate connections. This worked great!

Works great. Allowed me to check each run of CAT6 in new construction to make sure they were correctly connected. More importantly, it allowed me to find a cross connect error and fix it. The device only tells you what type of error you have. You still need a VOM to identify the location on the cable run.

I purchased this item to assist me with the wiring of CAT 5 cable throughout my home. Unfortunately however the device wasnt able to determine a crossed wire. I had alot of troubles with the crossed wire port. So I borrowed a more advanced system from work - it was able to determine the issue. I was a little disappointed. I would say however that the device would work really well for just ensure that ports map. But leave it to the advanced equipment for intense troubleshooting.

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.
