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.

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.

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
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!

Further to the above, if you have been swapping connections around it is always worth double-checking that you have got these correct!
In particular, I would double check that the BM7000 AUX/TV socket is connected (with a 7-pin DIN) to the Audio Aux Link (AAL) socket of the BL1614 converter.
If there are no speakers connected to the BM7000, you should also have a Powerlink connection from one of the BM7000’s PL sockets to the Powerlink socket on the BL1614.

The main speakers are Beolab Pentas, and they are both plugged into the Beovision 7. The left one is also plugged into the Beomaster powerlink, beacuse if it’s not, there is no sound from the Beomaster.

That could be part of the problem! The pentas should only be connected to the TV.
You should then put the TV in V.OPT 2, and the BM7000 in A.OPT 0. If correctly connected and in the correct option settings, pressing an audio command should result in the BM7000 playing through the speakers connected just to the TV. I would suggest that this part needs to be correct before adding the BL3500 into the mix.
EDIT: To add the Option setting procedures:
Turn system to standby/off.
For the TV: On a Beo4, press the POWER button and LIST together. Then press LIST until OPTION is shown, press GO (centre button), and then press LIST to show V.OPT. Then press 2. The power light on the device may blink to show that it has been accepted.
For the BM7000: Again using Beo4, press the POWER button and LIST together. Then press LIST until OPTION is shown, press GO (centre button), and then press LIST to show A.OPT. Then press 0. The power light on the device may blink to show that it has been accepted – actually the BM7000 may show a 0 in the display, I can’t recall.

When I set the OPTION on the BM to 0, it displays 0. When I set the OPTION to V2 on the BV, it displays nothing. The PC function on the BV (I only use Apple TV) has sound and vision, but nothing comes out of the BM.

This was a problem I solved by setting a powerlink between the BM and the left Penta, after everything else failed.

I assume that you have already disconnected the PL lead between BM7000 and Pentas. If not, please do so.
Does the TV’s standby light flash once when setting V.OPT 2?
If set up correctly (and with BL1614 between TV and Beomaster), you should be able to press (eg) RADIO on the Beo4 and the sound emits from the Pentas connected to the TV.

Yes, I disconnected the PL lead between BM7000 and Pentas. The TV’s standby light does not flash at all when setting V.OPT 2. So something else is off, apparently, since the same thing happens again, as before I connected the BM to the BV. I had the 1614 apart last time I tried to solve this, and it looks OK.
Can I draw the conclusion that something is wrong with the BV7? It has a HDMI converter… oldish…

Have you tried a different Masterlink lead between BL1614 and the TV? If possible replace and then try option setting again. Also try setting the TV’s V.OPT with no masterlink connected – it should still respond – try changing between V.OPT 1 and V.OPT 2 (leave it in the latter setting).
And check inside all masterlink sockets for any fluff or debris that could make for a poor connection.

Thank you! I will do that next week. Till then, have a good weekend and stay tuned!

So, here is the situation, so far:
I loosened the Masterlink from the 1614 and tried it in the 3500 socket. No sound.
I have acquired a teleplug to DIN from Steve, and have tried this with my phone and with my ipad. The phone plays on its own speaker, while the Ipad goes silent. Nothin comes out of the 3500.
Also, I checked the aftermarket Masterlink that was installed to join the 3500 to the system, using a Fluke 115 multimeter.2 and 3 do not beep against anything at the other end of the cable. 1 beeps against green and green-white
11 beeps against blue
12 does not beep against any of the leads in the other end of the cable
13 beeps against orange-white
14 beeps against orange
15 beeps against red-white
16 beeps against red
The Beomaster still needs to be connected to the the first Penta for any sound to emerge from them. The Beomaster and the 3500 respond to OPTION, by showing the number. The Beovision does not.
