I don't know of any graphical pin outs out there but do have instructions
which is easy to follow:
UTP CAT-5 wiring specs:
Four pair wire is the standard with Pair 1 as Blue, Pair 2 as
Orange, Pair 3 as Green and Pair 4 as Brown. Colors are always
shown with the Base Color first, then the Stripe Color. The
RJ-45 is wired as follows:
Pin 1 White/Orange Transmit -
Pin 2 Orange/White Transmit +
Pin 3 White/Green Receive -
Pin 4 Blue/White
Pin 5 White/Blue
Pin 6 Green/White Receive +
Pin 7 White/Brown
Pin 8 Brown/White
Two notes - First, holding the cable in your left hand, with the
RJ-45 pins facing up, Pin 1 is the furthest away from you. Second,
the blue and brown pair are unused and there is a big discussion
on whether you can use them or not. The feeling seems to be that
digital telephone is OK, but analog telephone (modem, fax) is not
due to the high ring voltage. I am running digital phone in the
blue and some System 36 emulation in the brown without problems but
most of my stations are on short ( < 150 feet ) cables. Still, the
safe money says to use the cable solely for one 10BaseT node and
put everything else in another cable.
To make a Cross Over patch cable for hub to hub connections, wire
one end as follows:
One End The Other End
Pin 1 White/Orange Pin 1 White/Green
Pin 2 Orange/White Pin 2 Green/White
Pin 3 White/Green Pin 3 White/Orange
Pin 6 Green/White Pin 6 Orange/White
Hope this helps
