Rj45 cable plugs and sockets

[nethystevo]

I have just finished wiring a house in cat5e cable and have connected up all the plugs and sockets, but after testing it with the continuity tester it comes up with non-parallel, this happens when the green and orange cores are connected in the socket, but when I take them out it says connected? Really confused with this.

Sounds like you have connected it incorrectly.

 

[nethystevo]

The connections are exactly what's marked onto the socket, this is why I'm struggling to understand why it is not working. I'll triple check my connections but I'm more than positive that they are the right way around.

Are you using a network tester, or a multimeter...?

 

[Plonker 3]

What markings does the module have on it, 568a or 568b?

also have you proved the test leads youmare using are working correctly?

 

[Lucien Nunes]

Sounds like one end is connected to 568A and the other to 568B, which are basically similar but have the green and orange pairs in opposite places. Most connectors show pinouts for both so you might have followed the wrong legend compared to the way you have done the plugs.

E: And Dillb is thinking along the same lines

remember there is 2 standards to connect to 586a and 586b
both of these will probably be marked on the outlet
it is very easy to get mixed up if they are both marked up on the outlet

 

[Dcf]

great minds think alike lucien

Null crosswork could be the answer, but a network tester would show they null pair

 

[nethystevo]

Right I've just had a thought, I have one end a socket and one end a plug, will this still work? Also I'm using both 568A on both ends.

 

[nethystevo]

this is the tester I'm using.

 

[tazz]

Looks like a null paired there....now which pair 1-8 are either not in sequence or not showing..?

 

[nethystevo]

Im afraid that's all the info this tester gives me that can be seen in the picture,

 

[Plonker 3]

Have you proved you both your test leads by plugging them directly into the tester and recieving unit?

 

[nethystevo]

I've taken a shop bought cable and tested that just incase but it says that cable is fine, would it mater that it's a plug on one end and a socket on the other?

 

[Plonker 3]

You need to prove the cable you are plugging into the ends you have made off

 

[nethystevo]

I'll swap the socket for a plug quickly and test it

 

[Plonker 3]

But the socket needs to be connected up exactly the same as the plug, you may correct the fault without actually realising it by doing that.

 

[nethystevo]

I have the socket connected up in the "a" terminals but I have already tried it in the "b" as well.

ok first thing, prove your test cables, plug test rj45 cable in transmitter and receiver and hopefully all should show connected. if all ok then move on to your installation, remove pairs one at a time until connected shows, but 2 pair numbers do not lite....swop the non lite pairs, to hopefully show connect.
