33670 2002-01-31 03:01:00 i was wondering if i can convert a normal cat5 rj45 ethernet cable into a crossover cable!
i was told that it can be done!
i got a rj45 cable and wishes to change the wires to make it a crossover cable

The wires should be as followed. 1st connector should be as is. Only need to change the 2nd connector.

1st connector 2nd connector
1 white/green white/orange
2 green orange
3 white/orange white/green
4 blue blue
5 white/blue white/blue
6 orange green
7 white/brown white/brown
8 brown brown

Hopefully you can understand that and hopefully I can get reassurance that it's correct as I only had the normal cable to go by.

Easier/cheaper than buying the tools etc you need to make your own.

33673 2002-01-31 03:22:00 Yes you can, I have done it myself, only because the crossover cable I bought once, although clearly marked, was not a crossover at all.

Here's a link to the wiring, scroll down for the crossover.

33674 2002-01-31 03:31:00 The cables have four pairs of wires, two of which are used.
The wires in each pair are twisted together -- that's why it is called 'twisted pair'. Doh. The two pairs used are from pins 1&2, 3&6.
The crossover cable swaps these two pairs. The spare pairs 4&5, 7&8 are not changed.

I think that KK's list is correct for the colours to be connected ... but check with these pin numbers:

1 crosses to 3; 2 crosses to 6;
3 crosses to 1; 6 crosses to 2;
4,5,7,8 stay as is.
