View Full Version : [SOLVED] RJ-45 Connector Problems...

So...today in my Networking class we were putting the RJ-45 connectors onto Cat 5 568B cables and I messed up both times. I hate connecting the connectors and cables! >_< Any advice/help on how to make them fit properly without bending or crossing over or anything so it works properly with the cable tester thing?

We're working on setting up a personal network for the classrooms. We have a lab station with 7 computers. 14 students, 2 to each group.

Patience and practice! You'll get to where you can do it above the ceiling grid in a restaurant at 3:00 AM when half the lights are off!

Well, we'll be trying again Friday. I think my lab partner and I are the only ones who weren't able to succeed. =/

It's a technique that comes from practice. (Can't learn to swim by reading a book). Straighten the wires and flatten them. A little long is OK - I presume your crimper has a section to cut wires to proper length. After you get the wires carefully inserted in the plug, give them a little wiggle whilst pushing. You should be able to see the copper wire touch the end of the connector. Although not easy to see, you can probably make out the wire color through the plug.

How do you "flatten" them?

I just pinch them between thumb and finger. Bending them back and forth a bit helps them "line up", but don't get carried away or the wires can break. Ideally, the wires should be straight and (relatively) parallel... and in the proper color sequence. It's usually easier to take the kinks out of the wires before you try to line them up.

Yeah, kind of like a hose when it has its kinks and twisted areas, right?

I have only done a few connectors, so I cannot offer advice on that.

But my Dad just taught me wind up extension cords or hoses over my elbow and I have always had the kinks. A while back I saw on Lifehacker instructions to create a loop in your hand and wrap the second loop on the outside but then the third on the inside of the existing loops, and keep alternating. I do not have kinks in hoses or electric cords anymore.:). (Video worked better than my explanation.)

Think you could link me to the video, oldfred?

I ended up Google this:
over under wrap cables

This was the one I remembered and use version 3.
