Ethernet patch leads RJ45 Jibber flibber....
As the title really!!
The village I live in has it's own wifi network. To get it I need an out door antenna and other thingy. I've got all the gear but I need
to run an ethernet cable from the outside of the house to the PC, which is, unusually, inside the house.
The guy who got me the gear could sell me a 20m ethernet cable for £6 which would do the job but it would mean drilling big holes to get the
connectors through. These holes go through two outside walls and then two internal brick walls. Instead I've got a roll of cat5 cable and a
bundle of RJ45 plugs and some plug squeezy pliers. WHat I'm struggling to get my fuzzy fat head round, is wiring up the plugs. I look on the
tinterweb throws up cross over and patch cables. I need patch cables. But there seems to be no definate colour order for the twisted apirs. I thought
as long as you wired both ends the same, then it wouldn't matter but the common theme is having pin 3 and 6 crossing over. Is this right and
why? If you're crossing both ends, then it's the same as not having them crossed. Or isn't it?
TIA, Owelly.

Hello,
Unless it says otherwise you will need a straight cable, so pin one goes to pin one, pin two to pin two etc.
Colours don't matter although there are conventions as to which normally go where.
The plugs can be quite fiddly to fit, so make sure you leave yourself plenty of spare cable at each end.

Easy ways of doing it would be to use a pre-made patch cable and cut it, then pass the cable through the wall and either punch it down into a
standard rj45 wall socket or just do a soldered spice on the cable.

Have a look at :http://www.alatec.com/info/rj45.html
have a practise getting the cable in the right order and at the right length, after you have done it a few times it's fairly easy.

The key thing in the link above is that the pairs used for Ethernet are 1,2 and 3,6 so as long as those are wired correctly it should work

i'd do one end, then use this as the outside the house end, drill the holes, feed through and do the other end in the nice warmth of the house,
not up a ladder / sat on a toad stool etc.
I've done them before and practice, test and leave some spare cable for doing it again

if i had to do this i would buy a long, moulded patch lead, chop one end off and pass through from the outside so the outside end is the moulded one
as they are more durable and will help keep water out of the plug.
pass the cable though and make off onto a patch panel or jack, i hate the crimped ends, into a switch and then plug your pc (s) into the switch, this
means you can connect multiple pcs, if anything is going to go pop (lightening) its just the switch and you dont have to worry about the crossover
(although your pc will probably do auto mdix)
im not keen on that though, cable should be outside rated (weatherproof) and you are at risk from lightening strike.
the 'proper' way to do it it antenna on the building, coax back to the access point with a lightening arrest or as it enters the building,
nice short run of cat5e from the access point to your switch / pc.

i wouldnt put a plug on the end, terminate both ends with rj45 modules in faceplates, gives you more flexibility and means that even if you damage the
plug you can just change the patch lead and not have to chop back the cable every time, if you need a couple of modules etc drop me a u2u i think i
have some lying around

Might be a daft question, but can't you put the antenna in the loft (assuming you have one)?
Different set-up granted, but I've got my wireless router installed in the loft along with a network HDD and Vodafone SureSignal.

one thing to bear in mind is that patch leads fail!
we install networks for business's and the best way to do it is to run the cat5 and terminate each end in RG45 wall plates / modules. use pre
made short patch leads at each end. easy to replace the patch leads if they ever go faulty. easier to fault find too.
if you are going to fit your own RJ45 plugs buy a good quality crimp tool. A £10.00 is a waste of time. if you dont have a test tool then you will not
know if the plug is good.
dont try to use a pair of pliers to do it

Contrary to what has been said here, the colour code DOES matter, the twist in the cable are different which result in a different interference
pattern. I alway go with the standard wiring I was taught and that goes.

Crimp the 6m RJ45 cable onto the back of the wall plug matching colours, then just run a second lead from the plug to your equipment

Cheers guys.
The antenna screws onto a 'Bullet2' thingy which is POE and has a waterproof gland for the ethernet cable so that end should be sound.
I'll wire uo the plugs as advised. I have a good set of crimpy things and out of the ten practise plugs, i've not had a bad one
yet.......or so the testery thing says.
I'll be off up my ladder later and i'll report back.
Cheers again guys.

Fitting an rj45 plug is easy just follow this vid
http://www.youtube.com/watch?v=v7H8OoKA4F8&feature=PlayList&p=5C7BB8584DE0E48E&index=0&playnext=1
But instead of untwisting the pairs after removing the outer sheath put a jewellers screw driver between each twisted pair at the sheath end and pull
it towards the end of the wire, this will remove the twist and leave you with fairly straight wires which make insertion easier.
Failing the above nip down to maplins and get a bag of 2 piece plugs, these have a little plastic doofah that you thread the wire into and insert all
8 wires into the plug as a whole which is easier for a newbie.
The vid shows the pinouts which are looking at the plug with the pins towards you.
Tridents method would be easier the only iffy bit would be the connectors at the rj45 socket end are made for solid cable and might not terminate
properly if you were using a multi strand patch lead.
You can get away without using an IDC tool just use the back edge of a stanley knife lead the wire from the inside of the terminal to the outside push
it into the connector then cut it off flush at the outside edge.
568b is the standard wiring plan.
Cheers,
Bob

Thanks guys.
I wired the plugs on as per T568b and job done. No grief with fitting the plugs and I'm now playing with 5megatrumpets for £5 a month!
