CrossOver Cable

To make a “Crossover” cable you change the pinout connections on one end of the cable. If you do it on both ends of the cable you have crossed-over the crossover and now have a straight-through cable.

Pins 1 & 2 from one end are connected to pins 3 & 6 on the other end, and pins 3 & 6 from the first end are connected to pins 1 & 2 on the other end. Pins 4 & 5 and 7 & 8 don't change. The pinouts looking from the bottom of the cat5 ends (White/Orange starts on the left) are as follows:

Standard End Crossover End
Pin 1 White/Orange Pin 1 White/Green
Pin 2 Orange Pin 2 Green
Pin 3 White/Green Pin 3 White/Orange
Pin 4 Blue Pin 4 Blue
Pin 5 White/Blue Pin 5 White/Blue
Pin 6 Green Pin 6 Orange
Pin 7 White/Brown Pin 7 White/Brown
Pin 8 Brown Pin 8 Brown
