Connecting cat5 plug to cable, Help? (1 Viewer)

[Lisa Space]

I have cat5 cable thru out the house, and now am upto the part of connecting the cat5 plugs to the wires. I have heard that there are two different ways to line up the wires in the plug before you crimp it. And it all depends on what you are going to do with the wires. Is there a web site that shows you what wires go where in the plug. Thanks for the help. This site has really been a big help in other projects.

If you're connecting computers to a hub, switch, or router, use the "straight thru" configuration (same colors on the same pins on both ends). For connecting two computers or two hubs directly, you'll use the "crossover" configuration (some colors are switched on one end).

Do a Yahoo search on "10base-T pinouts" and you'll find numerous sites with the color configuration.

The color order, when facing the end of the plug, from left to right is: brown, brown/white, green, blue/white, blue, green/white, orange, orange/white. If you're going to a hub, you'd wire both ends this way. Looking at it this way, pin 8 is on the left and pin 1 is on the right, so a pinout listing may show the colors in the opposite order.

For a crossover cable, you'd swap the following pins on one end of the cable: 1 & 3 (orange/white and green/white), and 2 & 6 (orange and green). So the pinout would be: brown, brown/white, orange, blue/white, blue, orange/white, green, green/white.

I assume you are wiring for ethernet (token ring or ATM are different). The proper term for the plugs would be RJ45 connectors. You can do a search on google for "RJ45 wiring" and find a lot of webpages with wiring diagrams. http://www.netspec.com/helpdesk/wiredoc.html looks pretty good, nice illustrative graphics.
Most of the diagrams show the male connectors so if you need to wire the female part just mirror the order so that the two connectors will line up the colors.

If you are asking which *standard* to follow:
T568A ..or.. T568B
it doesn't really matter, as long as both ends have the same standard.

This site also has some tips/hints:
NETWORKING CABLES
If you were asking if you needed a "Straight-Thru" cable versus a "Cross-Over" cable ...then disregard this whole post.

Good luck,

The setup is this: I will be connecting the cat5 cable from the modem to a Linksys Router, then the other cat5 cablings will go from the router to their located outlets. Was not sure what to use crossover cable or straightforward cable. Thanks

There's nothing unusual in that setup. Use a straight cable for everything.

Switch to switch you have to crossover the transmit/receive, but switch to PC or router to modem you should be able to use a straight cable.
