EIA/TIA 568B moving towards 568A

Seems that the EIA/TIA 568B wiring standard for Cat5 is possibly getting pushed out by in favor of EIA/TIA 568A. The only difference between the two is that flip pars 2 and 3 (OrangeWhite/Orange & Orange pair gets swapped with the Green/White & Green pair). My readings say that all new wiring installations should use 568A espically if your running Gigabit Ethernet. Most patch cables today in the US at least are using 568B. I doubt there will be any difference if either standard is used all things will still work the same. The other thing I did find out today is that CAT5 cable lenghts can be to small. None should be under 3FT and the minimum recommended length is is 7FT to avoid any problems at all. You can use some under 7FT and they will probally work fine but don't use any under 3FT. Gigabit seems to be effected by length more than any so try a longer cord if your having problems and make sure it is CAT 5e. I will note that I have made crossover cables 6 inches long and they worked fine. Just keep the length in mind if weird things start happening if your using under 3FT cat5 cables.

How to make a ethernet patch cable

These are instructions on how to make a cat 5 patch cable.

p>To make a "Patch" cable you just need to follow the EIA/TIA 568-B standard.

Pins 1 & 2 and 3 & 6 from one end are connected to pins 1 & 2 and 3 & 6 on the other end.

The pinouts looking from the bottom of the cat 5 ends (White/Orange starts on the left) are as follows:

     Standard End                          Standard End

       Pin 1 White/Orange                   Pin 1 White/Orange

       Pin 2 Orange                         Pin 2 Orange

       Pin 3 White/Green                    Pin 3 White/Green

       Pin 4 Blue                           Pin 4 Blue

       Pin 5 White/Blue                     Pin 5 White/Blue

       Pin 6 Green                          Pin 6 Green

       Pin 7 White/Brown                    Pin 7 White/Brown
 
       Pin 8 Brown                          Pin 8 Brown

How to make a crossover cable

These are instructions on how to make a cat 5 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 cat 5 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
