**Need help Fast: cat5 pin outs

I am about to run a cat5 cable between my basement to my bedroom. I have the cable, and wall connectors. Basically, I have two wall connectors and the cable connecting them. On one end I will use another cat5 cable between the wall to a hub in the basement. In my bedroom i will hook another cat5 cable between the wall to my computer.

Basically, what i want to know is, for the wall connector, how should I wire it? Do I use the straight through (A) wiring diagram, or should I use the crossover (B) wiring diagram.

Thanks for any help.
 
Straight through. If you need a crossover, use a corssover patch cable. Otherwise it will just add confusion if you need to do any modifications later.

Note that they have their numbers mixed up, the 568B is actually 568A. If you're not making a crossover cable, go with the one they list as 568B on both ends of the cable, because that's actually the standard one.

Can you clarify? The 568A looks like a straight through wiring as it says in the article, what is mised up again?

Also, I just want to make sure that is the same diagram if you want to make a female to female link?

Thanks.
 
Yes, use the same diagram no matter what, as long as you're doing straight through.

The 586A or the 586B will both work for straight through as long as you use the same one on either end. A crossover cable is made by using 586A on one end, and 586B on the other end.
However, a traditional straight through cable uses 586A on both ends -- 586B on both ends will work just fine, it's just not the "standard" way of doing it.
For some reason they have the images backwards on that site, so what they call 586B is actually 586A.
 
568A and 568B are both valid configurations. If you have both ends as "A" or both ends as "B" you have a straight -through configuration.

An Ethernet crossover swaps 1&2, 3&6....the same two pair are different between 568A and 568B. The effect is that a crossover cable is 568A on one end, and 568B on the other.

Good Luck
