Guys, unbelievable, I found the issue. Thanks again for the hint with the newest version of the Beolink Handbook v1.9.
I referred to the v1.5 handbook which I have saved a couple of years ago on my computer.

The RJ45 / masterlink pin occupation is on the RJ45 side wrong described. See the attached picture.

After I have changed the sequence all my problems are solved. The BL 3500 is working and my ML/NL BLC is working perfectly.

You are right, usually I should change the cable. However the cable is in the wall which is plastered. I will measure the wires at the end of the ML plug and check if pin 3 and 12 are connected.

Unfortunately it was not the resolution.

Must anything wrong with the cable and plugs or with the junction box.

Checking the ML status I got the error code “2”.

For masterlink to work, must pin 3 and 12 be connected to the masterlink plug?

Thank you for the hint! The shield is not really connected to the blank wires. I will try to connect and give an update.

Took now a couple of weeks to dive deeper in my installation.
I am not sure but I believe I faced an issue with my masterlink wiring. Unfortunately I have the cables in wall.
I have mixed the old ML world and new NL world by connecting with a ML/NL converter.
I bought a cable with a ML plug on one side and a RJ45 plug on the other side. Thought it would be good to connect to the converter.
Cut this cable into two halfs in order to have to ends for connecting my devices and used a junction box to connect all 4 devices.
The rooms with the standard old fashioned ML cable (9 wires) working perfectly, what means the BS 9000 delivers sound to the bathroom.
The devices (BL 3500 and ML/NL converter) connected by the cable with the ML /RJ45 plugs are not working.
The CAT7 cable provides only 8 wires and the ML cable provides 9 wires. I know the white / blue wire is bridged with the pink one.
Could it be that the ML sense is not working without all wire on the dedicated pins.
The BL 3500 shows no reaction (in the bathroom it is working properly) and the converter shows also no reaction.

I hope my english is good enough that you understand my concern. 🙂

Thank you for your support.

Thank you! I found the issue. Connected the Speaker to another Room. Works as expected. Seems I have a problem with the wiring in the junction box from where the cable goes to the place of the BL 3500.

Hi Johan,

Thanks for your reply! I have the manual however I find not the right setting.

I changed now to Source Center as I only need N.Radio or N.Music over ML.

Never the less nothing happens. The A6 is connected as primary. Secondary is non.

I will not get any sound from the A6 to my via BLC connected Beosound 9000.

Will try other settings but these makes for me the only one which make sense.
