Crossover Cables

In order to make what is commonly referred to as a "Crossover" cable one must 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, albeit a very non-standard one. In this case two negatives do make a positive.

You need to make a cable where 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 are unchanged.

The two ends look like this:
