Earlier on i this thread i did some testing where I connected the Beolab 3500 MK1 MCL connector on some of the products I had then.

I managed to do some control of a Beocord 3500 connected to a MCL2AV by controlling it from the Beolab 3500 IR eye.

However using the powerlink connection on my Beocenter 6 to connect to the Beolab 3500 I was not able to do anything

Since then I have got some more B&O stuff and have now tried to connect the Beolab 3500 MK1 to the powerlink connections on Both a Beomaster 4500 and a Beocenter 9300.

The cable for this connection is wired like this:

Powerlink pin 2 – > BL3500 pin 3, 5 and 7

Powerlink pin 3 – > BL3500 pin 1

Powerlink pin 5 – > BL3500 pin 4

Powerlink pin 6 – > BL3500 pin 6

In both cases I was able to control the sources on the Beomaster and the Beocenter, and the Beolab 3500 display was showing the source that was playing. When i blocked the IR eyes on the Beomaster and the Beocenter they would start up in a muted state like when the are controlled from a link room.

This setup more or less corosponds to the setup where a Beolink passive / ML-MCL converter is used to convert powerlink to MCL.

This explains why this works. In this case however the amplifier is not nessecary as the BL3500 is an active speaker.

Not the usual bottle opener design

Unfortnuatly corrosion is showing its signs on it.

My father tells me that is was given to the employes when 100.000 of the type 39xx series TV was made.

This my father used when he was doing layout sketches of PCB traces for B&O tv’s in the 80’s before it was compuerized.

I remeber he had some black tape in different withds and alsosome small round dots to use where the component legs should be.

One other thought: My original BeoSound 1 (used for tests) is at SW version 1.3, and my newer one at SW1.4. I think that the later BS1s (with built in clock) have SW versions 2.X. – I doubt that there are any differences and if anything B&O would probably reduce any link capability in the newer versions. Any idea of your parents’ BS1 SW version?

I just checked this as I am here. There are two different version numbers. The APP version is 2.5 and the OS version is 1.0.

I am at my parents now and have the logic analyzer hooked up to pin 6 and 7 on the AUX connector on their Beosound 1.

As might have been expected I don’t see any reaction to any commands I try to use on the remote including A.MEM which activates the AUX connection.

So i guess that we can put down any hopes of control options through this connection

I just wondered if there was any further progress on getting the CD working on your Ouverture?

Not more than described in this thread. I still have the issue where I have to press CD twice to make it play.

Guy wrote:

I also found a YouTube video that may be useful, here:  https://www.youtube.com/watch?v=0tmWOhNxZpI

I also used that video a lot when I disassembled the Ouverture. Very good althoug a few details I couldn’t see so had to find info elsewhere.

As I see it I can try three potential fixes: Deep cleaning of laser New laser kit Replacement of SMD caps on CD driver board I don’t have any time until next week at the earliest, but my current plan is to dismantle CD module and clean, and order/fit replacement capacitors.   Based on experiences earlier in this thread, I will try to avoid replacing the laser at this stage. Any thoughts?

Well I did not have any luck with the deep cleaning of the laser.

But the replacement laser also did not work that well before i replaced the SMD caps.

My tactic was that it couldn’t hurt to try the deep cleaning og the laser other that taking time, and now I have got some good practice in disassemebeling the unit.

Btw. I have also tried to put the original laser that was deep cleaned back in just to see if it would work with the new SMD caps, but it still had the original issues.

The connectors are actually a little strange – the external contact has a small plastic sleeve on it that will slide up and down. I am not sure of the purpose, but it does need a bit of force to push it into the MCL2P socket, whereupon there is a positive ‘click’ once fully inserted:

Interesting with the design of that connector as the connector I am using for mine is not sitting very well in the socket, and as the MCL2AV is designed to have the connections downwards this design would sure help to keep the the connector inside.

CD not working!!!  It tries to play and then I get the < > (no disc) display.  I took the back off and put it in test mode.  The CD tests all run smoothly will the laser coming on, trying to focus and full linear movement up/down.  Trying to play CD in TESTMODE then gives a Focus Error 2.  I’ll investigate further but possibly hijack your Ouverture CD thread, as I think it’s the same CD module

Sounds like some of the same issues I had. Although I dont thinkt the focus error appearead on my ouverture.

Sadly this will have to wait a few days due to my engaging in a silly concept known as ‘Dry January’!

Oh well then we must wait a little to hear about it 🙂

MCL2P with Original Instructions and the 15v cable for powering MCL2AV,

I did not expect the 15V cable to be gray, but what do you know. On the other hand these connectors was also used on the Beolit power supplies so they might have had plenty in stock.

All will be carefully tested over next few days and I will report back any interesting findings!

Very intererested to hear about the testing of the bottle opener and if that will bring interesting findings 😉

Thanks, will try to get a 1611 and MCL 2AV. Interestingly in this thread https://archivedforum2.beoworld.org/forums/p/23421/194049.aspx it is mentioned that the version number of the 1611 matters…..

None of my 1611 converters has that long type number, but have proven to work for several configurations from this and other threads.

I think the important thing is you do not get a type 1614 converter as it can not act as an audio master.

Both my 1611 converter has SW 1.3, and I have yet to see one with an other software version

Did somebody test 1611 with a beomaster 5 to get AUX-in? I`d like to connect a beogram 5500.

The Beomaster 5 I have is dead, so haven’t been able to test this scenario. However I can’t see no reason it shouldn’t work as it would be the same as having the Beomaster 5 and an other Beomaster/Beosound/Beocenter in the same masterlink network.

gebi wrote:

Is Datalink to control beogram also supported?

To control a Beogram you would also need a MCL2AV. The setup would be much like usecase 5 from my earlier post https://forum.beoworld.org/wp-content/uploads/2023/12/Beolik-Converter-Usecases-5.pdf

Not sure how the option settings on the Beomsater 5 should be as I have yet to use one.

Note that if a MCL2AV is used the Beogram is connected to the CD connection and controlled with the CD command. That is however a good thing as the phono command is the same as N.MUSIC and would introduce a conflict.

Although I have a hard time figuring out how you interpetered all that data from my screenshots 🙂

I have my doubts that the saleae software has a built-in decoder for such pulse/space length encoded protocols. It is not really commonly used.

Ok, good to know that it might not be the way to go for interpret datalink commands

I wondered if there’s any way this concept could be extended to receiving input from one of Beolink ‘black boxes’ to received input from a remote ML device.

Well I have had the same thought. The Beolink active has a fixed  audio output of whatever is playing on the ML network according to this post https://forum.beoworld.org/forums/topic/beolink-active-1636-pc-input/#post-14762

However activation is another thing. For the Beosound 1 to play sound from AUX the tape command has to be used. But when that is used the Beolink active will also switch to that source. Same problem if you wan’t to play CD from the Audio master on the ML network. By pressing CD you will also trigger the internal CD in the Besound 1.

A work arround could be to put the Beolink active in option 4 so it will only respond to Link + commands. This will of course make for some extra key presses to active both the AUX on the Beosund 1 and the source on the Beolink Active

Nice and now we know what’s the difference between the BW1 and a normal PL output. I see following in your BW1 capture (second screenshot equals the previous message): 0011 0001 1110 0111 1111 0000 0000 1001 0011 0011 0100 1100 1011 0000 0000 0101 0000 0000 0001 which equals those hex values: 31 E7 F0 09 33 4C B0 05 00 1 The Active kit sends the following: 0011 1011 1100 0000 0100 1000 0110 0100 0001 1000 1 0011 1011 1101 0001 0100 0000 0000 0000 0000 0000 1 which equals those hex values: 77 80 90 C8 31 77 A2 80 00 01 At least that “33 4C” data block I think I have seen before on AAL/MCL communication.

Would it be helpfull if I export the data to some binary files and upload them in a post?

Now I have a logic analyse and have tried connecting it up to the datalink pin 6 in the powerlink connection between the BW1 and the BL3500 MK2:

When activating the BL3500 MK2 via the BW1 with an ATAPE command I get this

Followed by this

Not that I am able to make sense of this command. But I have insted tried to compare it with the datasignal on pin 6 in a powerlink cable from a Beolink Active conencted to the BL3500 MK2

I can see that there are some differences in the structure of the first two parts of the signal, but also the part from the second picture from the BW1 data signal is not at all in the signal from the Beolink active, so clearly a different datasignal from the BW1 compared to a Beolink active

 

When presing standby with the BW1 connected to the BL3500MK2 I do not register any data at all. Probably the Bl3500 turn off because the powerlink on signal on pin 4 disappereas.

Hello guys and thanks for all the inputs.

Glad to hear that I am on the right track.

Now I will try with some different commands and see if I fully understand it.

I have got one now and it is working with the Saleae application with the excaption of the channel naming on device being 1-8 and ind the applicattion being 0-7, but I think I can mange that.

I wan’t to be comfortable using it before I am visiting my parents again next weekend and doing measurements on their BS1.

Therefor I have done some testing with different data sources, and can see that I might need some verification of what I am doing.

I have taken this screenshot from a recording of an A.TAPE command on the tape port on a MCL2AV:

What I need to know is does this look correct, or do I need to do some settings in the Saleae application?

Also if I export the data in binary format what is the best way to compare them to those datalink commands that are available in different online projects?

I have found a HEX editor, but unsure what format I must show the data in to be compareable (BInary, HEX, Decimal ??)

Thanks in advance

Is there a red LED with lights on?

If it is the later version of the BL3500 (MK2) it will not react to source commands if it is not connected to an audiomaster.

To check for signs of life you could try to press Menu, 0, 0, GO on your remote (is it a BEO4 remote you have?)

This should give som basic information in the display like sw version

Good to hear that the problem was solveable and your setup is working again ?

Sad to hear that it ha come to this point although I fully understand the reasoning behind it from your perspective Lee. Good luck on finding a buyer.

I just hope that the forums can continue to exist in some form in the future.

Regarding the Archived forums, the product pages, the FAQ’s and the Beotech sections, and also the current forums those can actually be acessed through the Wayback machine on archive.org.

However none of the search, and/or filtering functions seems to work in these archived versions of the pages, so a very manual process to find information that way.

One thing to notice. If my memory serves me well maybe the 0 button has to be pressed in and stay in for the TV to be off.
