MAsterlink mess

[lenhi]

Dear B&O community

After dismantling my MCL system, I am now trying to get my 3500 to communicate with the system, consisting of Beovision7, and Beomaster 7000. It worked fine for a while, paralell to the MCL system, but after I had the Beomaster renovated, changing an old capacitor, the 3500 won´t communicate with the system. The Masterlink cable was installed by a tech from B&O, but it is an aftermarket issue, and has a blue, a red, a brown, and an orange wire, plus four white ones.

I am working with the multimeter, and have gotten as far as the 3500 responding for five seconds to the RADIO command, e.g.

The system is wired through a 1614 connection box, and I think – but cannot verify – that the Beovision is master. The wiring from the BW goes to a small, white connection box, B&O issue, where Masterlink cables to the Beovision, the 1614, and to the 3500 are inserted.

Now I have been told that the voltage from the Beovision should be around 10-14, and the Fluke 115 says 10.98-10.99 when I measure on  the ground to blue and ground to pink.

I have also been advised to go to the MENU in Beovision and from there to LINK, where I should find Masterlink, Beolink, but those options do not appear. I am at my wits end.

Have you changed the settings on the Beolab 3500 to ML ON?

If not press Menu+0+9+GO The display should now show ML ON or ML OFF. If it is off use up or down commands to change to ML ON

Afterwards you can check the connection by pressing Menu+0+2+GO The display should now show ML OK if it is working or else NO ML or an error code.

I just tried that one, pointing at 3500 with the system in standby, and then in with the TV on. No reaction at all on the display of the 3500. The only reaction I can get from the 3500 is the five second Radio, or TAPE, or PHONO display.

I think we previosuly discovered that on later software versions, there may be a need for pressing MENU twice, i.e: MENU MENU 0 9 GO

Worth a try!
