Crossover pin configuration:
In order to make what is commonly referred to as a "Crossover" cable one must change the pin out connections on ONLY 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.
