How to Wire Your Own Cables - Industry Standard CAT-5 Pin-out
The images below depict the cable pin-outs for straight-through and cross-over Cat-5 Ethernet cables that conform to EIA/TIA industry standard for 568 A and B. If the first and second pin are orange, the cable is 568B. If the first and second pins are green, the cable is 568A. If one end of the cable is A and the other end is B then you now have a cross-over.
