Masterlink -> RJ45 Cable (what is the right connector)

27 replies

Hello together,

 

as I now have completely set-up and tested my B&O Masterlink installation it is time to hide all the cabling. Therefore i installed CAT 7 into my house some time ago. To connect everything I need a bunch of ML -> RJ45 Cables (15 pieces). As these cables are quite expensive and I have enough masterlink cables I wondered if i could cut the ML Cables into two pieces and attach RJ45 connectors to each end.

 

I understand this is the right cabling:

 

PIN  CAT    Masterlink
 1 ws/or rt (16) 
2  or  ws/rt (15) 
3  ws/gr  pink + ws/bl (12+13) 
6  gr bl (11) 
5  ws/bl  ws/or (13) 
4  bl  or (14) 
7  ws/br  gr (2) 
8   br ws/gr (1) 
   gnd  gnd

 

Do you have recommendations for the right RJ45 pConnector as there have to be connected 2 wires to PIN 3.

I have just tested several RJ45 Plugs but the original one from B&O seems way longer than normal RJ45 plugs. Is there a recommendation how these cables are made right? Do you really crimp two cables on one pin or do you connect the cables first together and the connect this one cable into the plug? Any recommendations would be great.

Hello Tim, I cannot help you with your exact question from experience*, but I could imagine you go the other way: find some good patch cables, cut them to the right length and solder an 8 pin din connector to the loose end. There you can easily make the leads come together. Maybe an idea?

*I did make some powerlink cables myself using RJ45 wall sockets, RJ 45 crimp plugs, Lumberg 8 pin din plugs and Tasker c207 microphone cable. I used these same cables in the wall, and I did not respect the wiring scheme B&O recommends :-)

Having read your question properly now: I think it will not be possible to run two of the masterlink cable wires into one position of the rj45 plug. There will not be enough space and you risk to not having a proper connection as the little blades are made to cut through 1 plastic wire lining only.

I guess it will be most easy (as you said) to connect the two wires first. With help of some heat shrink tube you must be able to use any good quality rj45 plugs I would reckon (irrespective of their length)

Or (last post of today) you could strip the isolation of (only) these two wires and twist them so that together they get the thickness of one isolated wire.

Keep all other wires isolated and crimp the connector. This is what I would try, and it would result in an elegant cable. Let us know what you will do!

This is a great tip. I will try that tomorrow as this sounds like a good solution.

Thanks a lot Johan :-)

Hi Tim84, were you able to make some functioning cables?

This is what I made....can it help?

Hi Zeus72, I think this is exactly what Tim is after: make two masterlink cables from 1 (with a bit of diy magic). Regards, Johan
