    Multi-Function F-Type, RJ-12, and RJ-45 Cable Tester

    Cable testing cannot get any easier than with the Monoprice EZchecker 008 Cable Tester.

    This tester is a quick and easy continuity checker for RJ45 (STP and UTP), RJ11/12, and F-type and BNC Coax cables. It tests each conductor on RJ cables and instantly provides a pass or fail result, with an indication of which conductor is faulty in the event of a failure.

    The tester consists of two pieces: the Master unit and the Remote Terminator, which can be detached from the Master unit by sliding it off to the right. There is no on/off switch or test button, simply connect the wires and get your result. Nothing could be easier!

    WARNING!!! Do not test live circuits as it could cause damage to the tester unit or personal injury.

    Note: This product has a universal card packaging that is used for PIDs 8129, 8130, and 8131, with the individual model marked on the back. The front of the packaging includes functionality tags for all three testers combined. Therefore, the packaging erroneously indicates that this tester is capable of HDMI cable testing, which it is not designed to do. For HDMI cable testing, please usePID 8131.

    Also note that the back of the card indicates that this unit can test USB cables. While it is electrically capable of doing so, the necessary adapters are not included with the tester.

    Looks good...
    Great looking unit and priced well...wish I have bought a different one since it is not reliable

    PROS: Nice, neat compact unit easy to use.

    CONS: Not always accurate. I have had it test cables and outlet connections as good but they must have been weak. Tested with another unit, showed bad. Replaced connectors and they worked fine. Too bad...otherwise I like it.

    CONS: Can't tell if you have a crossover cable.

    Response from Monoprice

    Thank you for your review and my apologies for the issues you have experienced with PID 8129. Unfortunately, it sounds like you may have received a defective product.
    Now if you'd like, I can help setup an RMA for a replacement. If you would like me to proceed with the RMA, all I would need is the order # this cable tester is under. Sorry again for the trouble and thanks in advance!

    Quick and simple
    The lights on this tool was quickly able to indicate where in the connection from the switch to the computer I was having issues. Specifically it has helped identify a loose punch-down on a drop and a couple of bad Cat-5E from drops to computers.

    This is a simple tool, as the price indicates. Advanced features for detailed troubleshooting and identifying issues should look at other tools. Those tools should be used for Full Time Network Admins and Engineers.

    PROS: Quick Simple

    CONS:, wish it came with some short RJ-45's for checking Patch to Drop.

    PROS: This is a steal at the price works great. Tests cable wire, RJ45, and Telephone wire.

    CONS: None

    A Must Have when rewiring
    When rewiring a building's network cable runs, I used this for testing. It was invaluable not only for checking specific wires, but also for diagnosing which wires go where as they were not labelled by whoever installed them in the past and were very disorderly.

    PROS: Great price, easy to use, comes with battery and case, works for multiple cable types

    CONS: none

    works just fine
    The house was wired with Cat 5e cable but none of the cables had crimped ends. I wanted to distribute ethernet across the house via a router in the laundry room and so was born a project. Crimping ends on cable isn't as obvious as it seems so the cable checker is a need-to-have to reduce frustration. What I did find out, though, was that all of the wires in the cable have to terminate at the same connector for the checker to work.
    I had to carry my DSL line on pins 4 and 5 (unused for Ethernet) across the house to the router. These were soldered to an RJ-11 cable and plugged into the input on the router. The remaining 6 strands were crimped RJ-45 (maintaining the standard pin-out config) plugged into a slot on the router and sent back the other way.
    The correct pin-out configuration was maintained and the wiring was straight-through . The tester would not recognize that Pins 1,2,3 and 6,7,8 were connected properly because pins 4 and 5 were not wired into the harness. The cable failed at the tester (showed no connections) but the cable was good because the router got signal and the computer connected to thje router without problem. Just an FYI in case anyone wants to try to use the unit to test individual pins - it doesn't seem to work that way. But it's not supposed to so it's not a criticism.

    PROS: You need one if you're going to make cables - don't even think that you don't.

    CONS: Not a multiplexer. ALL strands have to be active for it to register

    Tests Continuity Alright
    If you are going to primarily use this for network cables, I would recommend product ID 8130 instead.

    PROS: Quick and easy to use.

    CONS: Does not test for short or crossed lines. Therefore, if the cable shows that it passes, it may still not be ok to use.
