Rated 4 out of 5 by from New tool for me This is a new tool for me and I have not had a chance to use it in the field. The first thing I noticed when I opened the package is that it comes in two pieces, but it does not come with a box or bag to keep everything together while stored. I will update performance as soon as I get a chance to use it.

Rated 5 out of 5 by from Great tool to have for low voltage Great product. Easy to use. Only draw back is that it does not come with a case to keep everything together. Also does not come with a cat5 or cat6 cable to use for patch panels, so you have to make your own but you can test them once you do!

Rated 5 out of 5 by from Great functionality! This cable mapper feels very solid in your hand. The functionality is awesome. I really like the ability to tone individual pairs within cables. I also appreciate the dial switch. Seems like they had Electricians in mind in the design phase.

Rated 4 out of 5 by from Innovative I was able to identify multiple lines at one time, so easy to use. Made my job easier and more efficient. The only complaint I have is that it could use a canvas case for the multiple tools that come with it, other than that I was impressed

Rated 5 out of 5 by from Reliable and Useful Highly reliable cable tester and mapper. The testing features for RJ-45 and RJ-11 cables have proven accurate. I haven't had a chance to use the coax test yet, but I am confident that it will work every it as well as the others.

Rated 5 out of 5 by from Got a cable -Map it! No matter if it is a phone line, cat 5 or 6 network line or coax, this tool will help you figure out the tangle mess of cables. Used this side by side with other name brand mapper and performed just as well as or better.

Rated 5 out of 5 by from Excellent Southwire Tool I got the M300P, Professional VDV Cable Mapper, Southwire Tool about one week ago and wanted to take my time using it to provide a proper evaluation. I read through the Operating Instruction Guide to make sure that I could appropriately conduct tests of COAX, Twisted Pair and Phone Cable using this tool. The tool is great although you need to purchase a separate amplifier probe like the Southwire Model T120AP in order to hear the tones generated depending on the type of testing you are doing or cables you are tracing. You can test individual RJ11, RJ45 (CAT3, CAT5E and CAT6), and COAX RG59, RG6, RG6Q cables which will indicate whether the cable had a Pass or Fail, Open, Short scenario. You'll see exactly what wires are Reversed or whether you have a cross over cable. It is great to see quickly exactly how the connectors are wired. You can additionally test cables indicated above in your home with the remote capability included. Testing your Phone, Ethernet or Video Cables is extremely easy with a nice easy to read screen. I'd recommend this product to anyone!

All of the RJ45 jacks, on 4 cables I've installed, test fine on pins 1,2,3 & 6. The other pin numbers do now show up on the lower line of the meter. Is this a problem with the meter or my installation?

Is here a case for the M300P?  And perhaps with the T120AP in the same case?  Hate to have them rattling around in the tool box.  If Southwire doesn't make one, has anyone found something that will work?

When in test mode, my M300P shuts off after 30 seconds. This can be very annoying if say, I am wiggling a cable to check for an intermittent contact. Is the 30s shutoff correct? Is there any way to disable this?

I just bought a M300P and tested three different patch cables to try it out and each of these known, good cables fail with only wires 1, 2, 7 & 8 showing up as connected and 3,4,5, & 6 as Open. Seems like it is defective. Is this common? Ordered online.

I have a long cable where the letter "U" shows up on the bottom row under the numbers 3 & 6. It should either be a number, blank or a dash. What does "U" mean?

Asked by: Seth
The ‘U’ would represent an ‘Unidentifiable Error’. From my interaction with customers, this has been a result of multiple wiring errors on one particular cable. Usually they terminated the ends again and the problem was resolved.

What is the maximum distance to test on twisted pairs? I often work with 700ft+ lengths of cat5/6.

Asked by: Marc Thiel
The max distance to test twisted pair is roughly 328’ (100 meters) for our M300P.

I bought the M300P. Does it have the capability to tell if a data cable is already plugged into something? I had one before that would indicate connectivity by lighting up numbers 1-8 to show that the cable was plugged into a switch, computer, router, etc

Asked by: Dave87
No. This unit will not be able to accurately inform if a data cable is currently plugged into something. This will primarily be used to map a cable’s wiring from the Main Tester to Detachable Remote.

Hello, I just purchased the southwire M300P. I’m curious to know if this unit has an auto sleep function 5-10 seconds?  After using it while still in my hand, the screen goes blank?  I usually have to push the mode button to bring the screen back.

Asked by: FrankCap
The M300P does have an auto-sleep function after a few seconds of not being used.

Does it have a "latching" feature to catch intermittent opens or shorts?

Asked by: Dr Pheelgood
This unit doesn’t not have a ‘latching’ feature for intermittent opens or shorts. The M300P will detect open or shorts after properly installing the tester and remote but this does not have a latching feature that can be left in place.
