Cyp cat 5 cable problem

[ses]

Hello
I have a customer that has a CYP 1H2HBTE system
With a sky plus hd box

The system has two tv sets in different rooms

I was asked to check the cat5e rj45 connections between the transmitter and receiver for the lounge and the connector seemed a bit loose so i said i would put new rj45 plugs on the ends

However once done this stopped working completely

I spent 5 hours with 3 types of RJ45 cat5e plugs and 3 sets of crimping tools trying to get this to work again but to no avail

Ive used my cat 5 tester to check my connections and all ok

I purchased a pre made cat 6 patch cable and it all works again


The cat 5 rj45 plugs seem loose when connected to the equipment
The cat 6 patch lead is nice and tight when fitted so i can only think my connectors are too small or not making contact properly

Can someone help me im a bit out of my depth now

Can cat6 rj45 connectors be slightly bigger externally?

Is there a special rj45 for this equipment

Help

Ok
Thanks for your help Dillb
I may have to pay the av installers £200 to come and have a look

The numbers seem to go not 1/2/3/4 etc

then you have crossed a core or two.

check the whites its easy for them to slip unnoticed into wrong slot in rj45 plugs (no such thing as cat5/6 plugs there rj45 or rj11 for telephone)

as long as both ends use the same order then it doesnt matter what colour you use.

No ive remade the ends 10 times and deffinately not crossed the cores in the rj45's

What i meant by the numbers quote is i can never understand how to make off cat5 modules

Just carry out a simple test by plugging both part together witha short lead and watch the numbers light up sequentially.

Im going to buy a 1meter patch lead tomorrow
Chop it in half and join it to my cat 5e cable via bt crimps
If that works i know its the connectors i was using

are you sure that cable is good? it wouldnt be the first time anyone has had a bad cable

Well the existing cable was fine before i messed with it
The problem was that the infa red receiver thing had got wedged under the sky box so couldnt communicate

I didnt realise this i thought it was the rj45 connectors that were dodgy hence how i started getting myself in this mess
