RE: Using RJ45 crimp tool

Can you clarify on the X-Over Wiring Order? Would It Be Like This :

> 1 White-orange	-----> White-green
> 2 Orange       -----> Green
> 3 White-green  -----> White-orange
> 4 Blue         -----> Blue
> 5 White-blue   -----> White-blue
> 6 Green        -----> Orange
> 7 White-brown  -----> White-brown
> 8 Brown        -----> Brown

TIA !

Yeah, this is a good point.  If you notice that on the 568B standard the
blue pair separates the green.  This is to prevent crosstalk.
Ethernet(10Mbps) and FastEthernet(100Mbps) both only use 4 pins which
correspond to 4 wires.  Pins 1,2,3 and 6.  I believe that TX are 1,2 and
RX are 3 and 6.  So it really doesn't matter what color you use where,
as long as there is a pair separating the 1,2 from the 3,6 (although it
would be silly to deviate from the standard).

Of course, I have been in some buildings where they just seem to make up
their own wiring standard!
