cat 5 networking wall socket problem
anthonymwright Aug-20-01 06:44 PM
I need to know how to wire up a wall socket for 586A without the internal colour card as i am am having the problem with figuring it out as some socket are No 1-6 and others are 1-1 2-2 3-3 4-4.

From your site I have learned the ethics of colours and TX-RX buth this does not help if I dont know which is the top or bottom, 1-8 pin when looking at the back of a wall socket.

I think your info is great on how to make cables but I cant find on the web any info as to ther wall socket and their colour codes with wiring.

Please, Please, Please, help me someone.

Wall jacks vary as to how the wires connect to the back of them. Wall jacks do not vary as to how the wires as seen from the front of the jack should be associated with the color of the wires attached to the back and should be arranged. There are two standards and they are shown below.


Looking from the front of the jacks. The only difference between the standards is that the green and orange pairs are swapped.
You can see that the jacks I use have different arrangement at the back than at the front, which conform to the standards if the wires at the back are attached according to the label on the back—hard to put in words…

If the back of the jacks are not color coded then I would suggest using multimeter or continuity checker (a few dollars at Radio Shack) to see what connects to what. I am writing an article at present to answer these questions in more detail. Larry

The key to fitting wall sockets as I have stated to Larry who is at present writing a whole chapter on this subject, is to disregard all colour codes on the socket, there is so many types and most with removable ID covers which are mostly put on the wrong way round.
You need to buy or borrow a LAN test kit usually around £60.00 in the UK, this may be a big outlay but you will forever be able to solve Network problems for yourself and others quickly as well as fitting wall sockets. I know this as I fit around 20 a week and every one was wired different.

1st: Print and keep hold off the 586A colour wiring codes from this fantastic sight.
2nd: At the Hub end make your own RJ45 plug corrctly and checkit,checkit,checkit, then put the Terminator end of your test kit on it.
3rd: cut the cable at the wall socket area with about 2 feet excess.
4th: Strip the cable back to 1 inch.
5th: Seperate and cut away the Brown and Blue pairs as they do nothing as Larry has stated, (he is right as well as God in my eyes).
6th: Put the remaining pairs into the socket and connect the tester to the outside.
7: Continue to remove and replace the 4 wires untill you have confimed with the tester which is wires 1,2,3,6.
8th: If your lucky then you will have 1,2,3,6, with Green lights and no Non-parity light (crossed T + R wires).
9th: Once you have 4 green light correctly showed then write down on paper, even draw a diagram of how that socket is wired, then pull them out and cut the cable back enough to fit the socket into the housing without squashing the wires.
10th: Before screwing down the wall plate chack again the socket from the outside.
11th: Once the socket is on the wall once again check it as you may have squashed a wire.


This is the only way to not waste time and to ensure you have a solid link to the Hub.

If you need more help then mail me through my web site. www.pcnetcomputers.com

All the best and good luck
