It is a 1636 with sw 1.6.

activation beo 4: Radio (BC2)

activation ir: „Play“

Are you sure, that you have used the PL output to connect the BL4000 (and not the PC input)?

MM

Yes - it is connected to the pl socket.

Good idea Ralf, i will see if I can  find an adapter for my phone and check PC Input tonight. 

For the time being:  Is there a special sequence how to  power up the system (e.g. TV first and link room thereafter ... or power up active first and plug in masterlink  thereafter .... or something else?)

Also: i joined the masterlink „like for like“. I somehow remember that zwo wires could (should ?) be joined together: pink and white/blue. Could this be a the problem? 

Thanks for your support. 

You know that you’ll need a special cable for this - not just an ordinary 5-pin DIN adapter!!!

I understood that you already have a ML network running

and

if the ML-plug works for a BS2000, it is not likely that the fault is in the ML connection.
