HDE RJ45 RJ11 RJ12 Cat5 Cat6 UTP Network Cable Tester for LAN Phone Wire Test Tool

This has helped me to add ethernet to every room in my house. The instructions don't really help much. It seems to be a fairly standard type of tester, since I found many YouTube videos showing how to use it. When I plugged both ends of a store-bought cable into the testers, both ran through the numbers 1 through 8 in synchronized order. I used two kinds of outlets - one that is built in to a faceplate, and makes you connect the colors to different colors (orange doesn't connect to orange, for example). The other end of the cable is wired to plugs which then fit into a faceplate with squares for the plugs. These had the wire colors connect to the same colors. I plugged the master into one end, and the remote into a far away room. The master lights up in order 1 through 8. The remote lights up in a crazy pattern. The switch on the master has 3 positions: off (left), middle, right. The middle setting was too fast to see the order of the lights. I finally realized that the far right was the "slow" mode. Once I slowed things down, I could see that some lights did not go on. I went back to those plugs, found loose wires, fixed them, and all the lights went on. I am still trying to determine if the crazy order is a problem. I have installed an Apple TV on one, and it works great. I have not tried the tester on phone lines. I am using Cat6 cables, and at least I know when it is not working correctly. (So far, I am still pretty inconsistent with crimping connectors on to the cable - this tester has really helped me to know each time I mess up.)

I have security cameras wired around the house with CAT5 and CAT6 cable connected between the cameras and a NVR (Network Video Recorder) Because one of my cameras has been intermittent, I started troubleshooting using one CAT6 cable from the suspect camera directly to the NVR bypassing the existing installed cable. With this setup, the camera reported properly. I then used the same CAT6 cable to test the installed cable and during the Network Cable Tester (NCT) operation, the scan process detected dimmer than usual indications on two conductors. I then went to the camera jack and existing cable plug and found a black substance on male and corresponding female copper conductors.Without this NCT, I may have found the cause of the intermittent problems but with a lot more time expended. With the dimming of the leds on the NCT, I quickly determined that most likely the cause of the intermittent operation was due to 2 conductors trying to conduct through corrosion e.g. resistance. The cameras operated properly when I used the bypass CAT6 cable but the resistance between the male and female conductors was basically 1/2 of the existing connection enough to result in continuity and proper operation.I have at least 2 choices: 1. to physically scrape the corrosion off the two conductors or 2. to use a material that will remove the corrosion. Most likely I will choose option 2 due to my shaky hands and the size of each tiny conductor. Failing that, I'll have to replace the cable.There you have it, how my morning went with the use of the Network Cable Tester. I’m very happy I purchased this tool.

I bought two of these 4 1/2 months ago and use them fairly lightly. They work well for just checking continuity but if you work with Ethernet cabling you know this is not a tester that will confirm quality. I had something very similar before that cost around $75.00 but its no longer manufactured so I bought these. I had very little expectation because of the price. but they seem to work well. 1 of the 2 units now will not light up for Pin #4 and looks to be a problem with the transmit side. For $8.00 its hardly worth dealing with a return. I would buy them again for I need them to do.

Our house came pre-wired with network cabling, but nothing was connected. During our internet installation, the installer showed me that you just need to find which wire comes from the connection where the internet router is hooked up, then connect your other cables, and voila. Home hooked up.This device worked like a charm. You plug a cat cable into the receiver, connect to the network wall connection, go to your network hub and keep plugging in various cables until you see the device light up. The whole house was figured out in about 20 minutes. Do yourself a favor and label those cables at your network hub. You'll save yourself some time in the future.

I was pleased to get this unit fo r the cost I got it at and even more pleased that it worked. I was a but weary about "buy cheap, get cheap" but I needed something less costly and functional so I could test all my Ethernet runs I was doing for a basement finish project, and to my wonderful surprise, when it came to testing, this worked like a charm. I was even able to test all the cable runs from the previous install to the rest of the house. IT works, it simple, its worth the $$.
