The first answer is at http://alltechdevelopment.netfirms.com/main/pc_medic/pinoutnetwork.htm

Be careful as the first information on the page is incorrect and will give you a cable with "crossed-pairs" that will only work on 10BaseT. Also the first crossed-pair diagram is for half-duplex only. The diagrams are useful, but use the ones at the bottom of the pages. The important thing to remember is that PCs use wires 1,2,3, and 6 for half-duplex and use these as well as 4,5,7, and 8 for full duplex. The color convention is usually 568-B or 568-A. Most use 568-B which when looking down thru the connector's flat side is orange-s, orange, green-s, blue, blue-s, green, brown-s, brown.

Usually you use a straight cable which is the same connection on both ends. If you need a cross-over cable, usually for connecting 2 PCs without a hub or switch, then switch the orange and green wire pairs at the other end as well as the blue and brown pairs if you need full-duplex. Think of the second PC recieving info from the orange pair on pins 3 and 6 and transmitting back to the first PC on the green pair on pins 1 and 2.

Also, the 569-A color scheme merely swaps the orange and green pairs.

This is for straight through cable
If you want to make a crossover cable, have the above on one end and on the other end switch 1 and 3, and switch 2 and 6
Good luck!

Just wire it soa that the wires are the same on both ends. I usually use wh blue, blue, wh green green...etc. This is the standard straight-thru cables you use to plug in to a switch or hub. There are also patch pannel standard wiring at
