    Default Cannot make a cat5 cable (GEEZ)

    I bought 1000 ft of cat5 cable, crimper, connectors and tester. I worked a couple of hours and only got 1 connection out of 8 with connectivity. ? Ok maybe the basketball game had something to do with it, but it should not be that hard, or maybe it is....
    I used the cutter to square the wire and then I stripped 1/2 in of the pvc cover and then I got the conductors in a sequence and pushed them as far as I could into the rj45 plug and then crimped. Bad result
    cut off the plug, repeat, cut off plug, repeat, cut off plug, I hope I get this to work.
    Maybe I should have bought the cables already made?
    Jesus is the Reason....

    Maybe…

    After untwisting the wires and ordering the wires, make sure that they’re flat, very flat. Squeeze them together so they’re parallel and tight up against each other. Then cut the end straight with sharp cutters; you don’t want to be smashing or fraying the wires. Then push them into the connector, making sure that they truly go all the way in. Double check one more time, that they’re in the correct order. Insert into the crimper, forcing the wires in tight and crimp.

    Yeah, I made a few bad ones also, but the majority was good. You feel more confident with each one. Believe me after awhile, you’re pretty sure that you could do this in your sleep.

    I think a Cat 5 video is in order! Give me couple days and I will make one.
    Thanks,

    You DON'T strip off any insulation off the ends, Just cut them straight, get the colors correct, and seat them into the connector and crimp.
    The crimping cuts through the insulation for you. If you pre strip them, it's too loose and can be intermitent at best.

    That is true. I could not follow if you stripped the individual wires and the jacket or just the jacket. I strip the wire so 1" of it is out and I order them then I use my fingers to flatten them and cut them straight ans carefully and fast I push them in the connector making sure they are still in order, crimp, repeat on the other side. Remember that what you do to one side you do to the other.

    I'm reading this and laughing and I'm probably the only one who has this trouble, but my biggest pain when making these is separating the green-green/white and getting them on either side of the blue-blue/white. For our use, couldn't I just flatten each pair in any order that I want as long as I do the same on both ends. I'll bet half my time is spent on spreading the individual conductors, making sure they go around another pair, and then get them all flat.

    You know like 568B be damned just stuff them in the RJ45 in an order they lay naturally. I will never ever use these cables for anything else, so do I have to stick to that standard?

    Yes and no...

    You are correct that as long as they are the same on both ends, then it will be a straight through cable and be electricly correct, But...

    For longer runs (RS-485) and preffered for most data applications, the data pairs should be twisted (If I remember correctly we're using 4 and 5 - Blue pair - My gear is in the garage at the moment - Someone correct me if I'm wrong.)

    The problem with what you are suggesting would be this:
    If you laid out 4 colored pairs in order, and stuck them into the connector, pin 4 and 5 would each have one wire from a twisted pair, and not be twisted together themselves.

    Does that make sense?

    (If I'm wrong about using 4 and 5 for data - Then repeat this in your best Gilda Radner voice - "Never Mind" )

    That makes perfect sense. I'm just not smart enough to know if 4&5 carry data as I just follow the directions that I can read. I just blindly make cables never giving any thought to it until I read this thread and I found myself laughing about it for some odd reason.

    What kind of crimper do you have.
    Your crimper should also have a tool for striping the insulation jacket.

    I was told to that most bad connections were due to under crimping so you were to squeeze as hard as you could and then squeeze some more.
    My result was that I was actually over crimping. Driving the pins so deep they could not make contact in the socket.

    If you do not have one look into getting a ratcheting crimper. As soon as you hear the click you know enough pressure has been applies to correctly drive all the pins to the correct depth.

    Can you give more information on which part is giving you problems.
    Are the wires in the correct order?
    Are all the wires fully seated?
    Does the crimp look good?

    If you got it on line, can you give us the website?

    Lets get serious, I have over 10,000 channels on my back, just where do you want to start counting.

    I found some that click when its crimped all the way and has some thing that I have to pull the RJ45 connector out of thecrimper before it snaps back to insert another connector. Pretty cool I think, the downside is once you start crimping on one you can't stop if you notice something its 100% crimp or 0%
