To be honest, I have no preference, I just followed whatever order guide was on my crimper. Didn't seem to matter.
Practically it doesn’t matter. I use type A because I memorized that order and it’s never caused a problem so I stuck with it.
It’s kind of a weird joke that type A and B exist at all. Both work. Neither solve a problem the other couldn’t.
Crimp both ends the same and it’s fine. But is funny to have this silly little debate.
There is a reason they exist. It called crossover cables from the days before Auto MID-X.
The days before 100Mb NICs you had to crossover somewhere for connecting 2 like devices otherwise both devices would tx and Rx on the same pins.
Yea I remember old crossover cables. But was the crossover type A on one end and type B on the other?
Yep
Neat!
I used a little self motivator to memorize B. "If you're blue inside, it ends in shit." That puts solid brown at the end, and keeps straight the blue/green pairs in the middle.
