as I am just playing around with some toys (Beo4, IR sensors, arduino) I just have to revive this thread, as I found out that the wiring stated above seems not to be correct regarding the MCL IR receivers (I hope that is the correct „type“), it may be another at that VX sensor: 5V power supply – green ground – brown data – white

I can confirm the colors in regards to the rectangular MCL IR eye. In case of the MCL IR eyes you should be able to count on the wire colors being correct as the connection to MCL2A and MCL2AV is with srew terminals where the wire colors are printed on the PCB next to the screw terminals.

For the Newer round type IR eye where the conenction on the IR eye is with screew terminals the color coding can vary depending on the product type it is used with and wheether a twisted pair ethernet cables is used for it, so in case of these IR eye’s it is better to look up a wirering diagram than depend on the color coding. This might also apply to the VX sensor IR eye.

The white will emit data: the pulses are high to low with a voltage of ~1.5V (instead the 5V of more modern IR eyes)

That sounds odd as the IR data signals are compatible across the different IR eye’s as tested in this thread https://forum.beoworld.org/forums/topic/beolink-passive-ir-eye/

Hi, I bought a truly as new BeoCom 6000 mk2 handset, to use daily. It must have been rarely used: the texture of the back cover feels really new, and the white texts on the buttons is really white still. I put a new battery in it and it works fine. Happy with it!

yeah the Beocom 6000 is a wonderfull landline phone. I had one as my primary phone for several years, but in the end it was not used anymore and was given away to another forum member.

Got two again recently that was part of a larger LOT of B&O. They are just placed as art pieces in my Beocave, but I might get to utilising the built in volume control

You are very welcome, and glad to hear that it did help even though it was not logical why.

I just did some testing both with a Beolab 3500 MK1 SW 2.0 and a Beolab 3500 MK2 SW 3.1 connected to my NL/ML converter setup as V.Master. I assigned the PC source to the Line in on the NL/ML converter. I used a Beolink converter type 1611 to power the ML network.

In my first testing I could not get sound, but then after changing the role of the NL/ML converter to A.Master and back to V.Master it now works for both Beolab 3500.

So it is possible use the PC command, I was just in doubt.

But one thing that came to mind, Which components do you have on the ML side of the converter besides the BL3500? Do you have a ML audio master, or a ML Powerbox or as I did here a type1611 converter?

Just asking to be sure as I don’t know if this is a setup you had for a long time or a new setup.

The role of th NL/ML converter is V.Master (I have a beosound 5 in the system too. In the NL/ML gateway, I assigned Line In – and I know it works because the Beosystem 4 can stream. I’ve tried assigning it to PC and while I can switch the beolab to PC, it doesn’t stream.

I am actually a little unsure how the Beolab 3500 handles the PC command. I can try to do a test of it tonight.

Do you know if your BL3500 is a MK1 or MK2? MK1 has the MCL engraving under the 8 pin DIN connector on the back?

Have you tried assigning another video source to the Line in that is not in use on the BS4 (provided the BS4 is in the same room)?

I am not sure if I understand your question correctly. But if you want to stream with a Chromecast through a BeoLab 3500, it is possible. If this is what you want … I do this via the DIN-connector and a Mini-Jack-to-DIN cable. In this case you need a cable that connects the right way to the pins in the DIN-connector. Then you have to use the Beo remote to activate the ML on the BeoLab 3500, and streaming works.

The soultion you are refering to is for stand alone use of a Beolab 3500 with a Chromecast directly connected to it. What Frog is asking about is a usecase in a combined NL and ML network where the chromecast should be available to more than 1 device.

what I can’t do though is get the Line-In output to play out on any ML device. I know that the NL/ML converter configuration is fine as I can select it from the Beosystem 4 – just can’t get a Beolab 3500 to stream.

What role have you given the NL/ML converter?

Have you assigned a source to the Line in that is visible on the ML network and is not used by other sources on the ML network?

It makes me a little worried if your Penta’s are connected to both the BM7000 and the BV7 with Powerlink. This could potentially make issues. Has it always been like that?

If the BV and the BM7000 is in the same room best practice is to connect the Penta’s to the BV7 and let the music from the BM7000 be played though the TV.

You will still need the preamp. The beolink converter only convert the signal types, no amplification

So cable-wise there is some hope but remote-wise it’s a different story? The fact that there’s no online evidence of someone who’s been able to pull this off on an old unit like this, seems like a bad sign.

Right. Of course there might be somewhere inside the control center were it can be switched on, but that would require both the service manual an some understanding of the circuits to figure out I guess.

With a cable to the other Penta, and that one connected to the other one, they suddenly work

Do the displays also work or is it only sound from them? If no display then It could very well be a fault on the datalink circuit on the Beomaster 7000. There is a transistor and a diode that can fail.

I am beginning to suspect theat there is something wrong with the Masterlink; according to your drawing, the powerlink is not used at all here, so I pulled that out when I needed the second plug in the Penta to connect to the other Penta. Since then, no sound at all from the BV7. And I have nowhere to connect it.

Remember my drawing is just how I imanginge that your setup is/was connected based on what I can read in your post’s to better understand your problem. As I have not seen your connections I can have misinterpeted some information, so the drawing is best guess based on how things usually are connected  Therefor the best would be for you to try to verify if the drawing resemble how your system was connected before the problems arised.

About the BV7 that should be connected via Masterlink so conenction to the Black Beolink converter Box. You might have a junction somewhere on the Masterlink connection where it is split to the BL3500.

I have just been experimenting with a NL/ML Converter connected to BC2300 via BL1611.  I can start the CD and skip through tracks, but my BC2300 also starts in a muted state.

I think the reason for this behaviour is that the way the NL/ML converter connect to a B&O music system is in many ways how it would work with a connected Beovision or a Link room where it is the speakers on the controlling unit (in this case the NL/ML converter just controlled via App or another NL device instead of a remote) that is started and not the speakers connected to the the music system

Unlike you, I can then use the Beo4 remote to unmute and control the volume

Do you still use the Beolink Passive for local speaker? That may give an other result than “real” Powerlink speakers

Hi again. I just tested the setup with a Beolink converter type 1614 and that also works. A type 1612 is identical to 1611 but for the US market so that would also work.

Hope this help to narrow it down

I just tested this again with the BS5 setup as Audio master in option 2 connected to a Beolink Converter type 1611, and I can indeed get audio input from the 1611 AAL connection when I press TV or any other video command on a remote.

With these settings eventual link rooms should also work in this setup

Location: Denmark

[Madskp]

It should be possible to get extra sources via Masterlink by the use of a Beolink Converter type 1611.

If you connect the converter via Masterlink the BS5 should be able to get the input from the AAL conector by using video commands like TV, V.MEM, DTV (it does not matter which video command is used) etc. This of course require that you do not have a B&O TV in the same room that also use these commands.

I did some testing of it int this thread https://forum.beoworld.org/forums/topic/beosound-5-a-mem/ where I also tested other possibilities.

If you need more info I can try to do a new test just to verifiy that I was not overlooking something when I did the testing in that thread.

Was a little curious about the BLC 1610 so I had to open one up to see what is ticking inside:

All pins in use on the two ML connectors are wired in parallel, so just kind of an internal junction box. What is unusual with the ML connectors is that pin 3, 4, 5, 6 and 12 is all connected where pin 12 is supply voltage +, and most of the others are normally no used. This however explains where this box is getting power as the same pins are supplying +12V on the diagram for the AV9000

One other curiosity is that next to the external 1-2-3 switch is an internal switch with 2 positions:

These are named:

• Central 1610
• Local 1611

Not really sure if that means it will function like a 1611 if it is in that position. Might do some more testing around that at a later point.

I found a MCL service manual on Archive.org that besides all the MCL2 stuff (also for the newer MCL2AV) also has the service documentation for the 1610 AV9000 Audio kit.

This reveals what both the internal and the external the switch do:

However a little disapointing for those settings where it is for future use.

With this knowlede I had to do a test to see if I could get it working. I have tried with my BC6-23 as Videomaster (V.opt 2) and my BC9300 as Audio system in A.Opt 0 and the 1610 with the external switch in position 3.

No result I could not get the TV to start the BC9300. Also tried to add more power from an external 12V power supply as the 1610 use som extra pins in the Masterlink connector for power, but still no result. I tried with 2 of the 1610 boxes I have with no luck.

And just to verifiy that the TV and the beocenter worked togheter I tested the connection between them with a Beolink Conveter 1614 in between and that worked flawlessly. I guess the 1610 boxes probably either only will work with the AV9000 ore are defective.

Just adding my 2 cents to this topic as I also think it would be cool to be able to repurpose this piece of art.

Looking at the service manual for the TV part of the AV9000 ( I have not seen on for the control center) I can see that the Masterlink connector for the control centre use a different pinout than the normal. For example the data +  and data – are on pin 8 and 9 instead of pin 1 and 2. They are interconnected in the TV though, so it is Masterlink data. Also the Audio part is on different pins and instead of being balanced audio in normal Masterlink it just looks like a left and right analog audio signal with a ground, so it it could be activated it should be fairly easy to supply an analog audio signal to it.

However the biggest issue is probably how to turn it on since the IR receiver is in the TV part of the AV9000, and is the probably transmitted as Masterlink data to active the control center. And since this principle has not be used for other products I have a hard time seeing what could substitute the TV part of the AV9000.

 

Speaking of AV9000 I have four AV9000 Audio kits in my collection. It is much like a Beolink Converter 1611 for connection to a audiosystem with datalink, but with two masterlink plugs and feed with power from the TV via some extra pins in the Masterlink cable. I have not been able to verify if they work since it’s a little special.

A little thought from me: what role is the NL/ML converter setup to? I am not sure it can work if the converter is setup as Source center as this will make source collission on the ML part.

This will not be the case for the BC2 if it is N.music compatible.

BS Ouverture does have Datalink yes, but it is what is called Datalink 80 and is used for controlling Beogram record and CD players, and Boecord tapeplayers.

Without knowing much about theLintronic box I think that it use the Datalink 86 protocol for communication and that is not available in the Ouverture’s AUX connection as the Ouverture has Masterlink. It is however available on the Beocenter 9300 AUX socket.
