Great you found out and got it working ?

Thanks for the clarification. Looks like I need to talk to somebody who said: “1611 where replaced by 1636, same with added features”….

But think about the combination of 1611,1636 and a pair of speakers will give you three easy remote controlable sources (Audio, video and PC).

nearly the dream scenario for the BL3500

Type 1616 (and 1618 for USA) is the first version with 2 x PL output sockets – that is the service manual that is in the Service Manual database. Type 1636 is the later model with one of the PL sockets replaced with a PC input socket. I think that this version was introduced as the Beoport was phased out, hence the naming of the input. The input pins are definitely 4, 2 and 7 – I have it playing at the moment. The connections are mentioned in the Beolink handbook on page 116: (although it states to use the shield as ground – I used pin 7 as shown in some of Peter Pan’s diagrams)

Ok that makes sense. Odd that the pin configuration on this input has to be special, but maybe a way for B&O to reuse the PCB’s in the box without to much changes

I entered a few final notes (in blue) about my attempts to trigger BL3500 using 5v into the MCL socket

One more thought regarding this test. In this thread https://beoworld.dev.idslogic.net/forums/topic/beolab-3500-how-to-fix-ml-input-selection/#post-13452 where Matador got the info about the trigger Pin assignments it was pin 1 and 7.

This would make little sense for powerlink where Pin 1 is power up and pin 7 is data ground.

But for the MCL connctor that it must be for the confirmed working unit with the low serial number and old software version it makes not as much sense as pin 1 is signal left and pin 7 is data shield (ground).

What if this Curios Dreamer misinterperted the pin numbers and had reversed them? Then it Would be pin 3 Ground left channel and pin 6 Datalink which would make more sense in my head. Note that Pin 3 ground is not directly connected to ground but through a resistor and a capacitor, so not quite the same as pin 7.

Don’t know if you already tried that combination Guy or are willing to try it, but here is the idea

. I also made up a lead to test the PC input of the BL Active, only because I had never tried that before. The PC input worked fine using pins 2, 4, and 7 for Left, Right and Gnd respectively. I could select using ‘PC’ on Beo4 and it worked as a local source, but as soon as I disconnected the ML it stopped working – so there is no simple BL Active standalone option.

not knowing much about the Beolink active I am s little confused about thisPC connection. It is not mentioned in the user-, reference or servicemanual availeble on Beoworld, and this older thread https://archivedforum.beoworld.org/forums/p/15997/128504.aspx mentions it but with other pin numbers.

has there been different versions of this product?

Perhaps the shorting (or otherwise) of ML pins 4 and 12 in early model BL3500s is relevant to our investigations?

It doesn’t say why they have to be shorted, and weird since pin 4 is normally not connected in masterlink.

What I can’t make of it is in most normal B&O link use cases the activation of the speaker will be from the speaker it self (or via IR). So the turn on feature might be a non standard thing

Or maybe the BL3500 manual is not showing all the connectors on the W1

Ok, so I confused my self, and probably also you. I misunderstood the drawing in the Beolab 3500 manual thinking it was showing the connections on the Wireless 1, but it is of course the connections on the BL3500. Sorry for that.

It is mentioned i the specification list in the servicemanual for The BL3500 MK2, and I also have seen manuals for the wireless 1 with drawings where it has Two powerlinks sockets and one Ir socket, and in a user manual for Beolab 3500 it only has one DIN socket and is connected via ML. So guess there must have been at least two versions of the W1

But I’ve also read many times on the forum that the Powerlink socket on the 3500 is there for use with W1. I suppose they were different version of W1 over time, one of which uses Powerlink and the other Masterlink, right? But even then, Why would the Beolab react to a Powerlink connection from W1 only and not any other device?

Just a quick note about triggering the BL3500 with 5V. I did tentatively try 5V to various pins whilst I had a 7-pin cable attached to the MCL socket (ML was disconnected). I tried all voltage injections variations that have been mentioned with ML turned both on and off. BL3500 did not turn on. Given that we now have BL1611 working well, I give up!

Out of curiosity: Did you try the combination +5V on pin 6 (datalink) and -5V on pin 7 (datalink shield)? I have had some thought about this and cam to the conclusion that the rest of the pins are either not conencted or used for the sound part. Furthermore one of the olde manuals regarding datalink signals mentions high signals in the voltage range 2.1 to 5.5V. But again it is just a thought.

Of course the downside is that for some reason my Mac forgot it had a paid license to LinkPlayer (the battery died during the 8 long years of storage, so on restart it thought we were in 2000, and then jumped to 2023)… and now the required esellerate.net servers don’t work, so I can’t activate my LinkPlayer copy even though I have the original receipt with a code —this limits functionality to one hour.

I read some of the threads about Linkplayer back then, but didnt realize (or remember) that it was a paid software with activation. That makes it a little more difficalt to rely on if it is not possible to activate anymoreå

I don’t suppose it’s because there is no picture. I seem to remember something about no sound if there is no picture but I am probably completely wrong!

it should work ok without picture. I had music playing through the analog AV connector on my Beoplay V1 (which is the same platform) the other day.

I use the original B&O mini DIN to scart adapter in my setup.

Forgot to ask, did you connect the BeoCord’s datalink to the AAL pin 6, rather than the usual Beocord pin 7?

yes, i have made an adapter to reverse pin 3, 5 and 7 to 1, 4 and 6

That makes perfect sense. It also explains … … why my modified DVD1 turned off after a long press. DVD1 had full control when connected to AUX/TV socket of BC9500, because the BC9500’s AUX/TV socket must have AAL at Pin 6. Given that I used a modified SCART lead, the data within SCART must be AAL rather than Datalink. … why my OneRemote has to be programmed to a strange number (starting with 4XX) when connected to either BL1611 or a TV’s SCART socket. This makes it use AAL rather than Datalink.

Great. Then we at least seem to have figured out what will work and what will not for that part.

Beolink Handbook shows Masterlink and Obsolete Masterlink wiring, pin 12 is “+ supply voltage” in both case, pin 4 is not connected in Masterlink and “+ supply voltage” too in obsolete Masterlink. Shorting Pin 4 and 12 would therefore mean “the device expect positive voltage on pin 4 but because we have changed our wiring, you have to take it on pin 12”. Right?

I took a look at the diagrams in the servicemanual for LCS9000/Bl3500MK1, and it actually shows pin 4 being connected to whats called V ml instead of pin 12, so this explains the text from the product configurator. Why it is made this way I cant see a logical reason for

sounds more or less as the experience I had with the BV6, 1611 and Beocord 3500. Didnt try the long press off though. Will test that for my next testing session

I came around to try this test, but the Beocord keept playing even though i tried various lengths of long presses.

Might be the difference between AAL an AL.

I am now trying a few other things on the Beoport and will then do those BL3500 MCL socket pin measurements.

Another research regarding this from on of Peter Pans drawings on Hifi4all, all in danish, Both examples is for connection of a 3.5 minijack to the DIN socket but without any power on functions.

First example is the MCL socket in LCS9000/BL3500 MK1. Again pin 2 is unused, and ground are on other pins.

The second example for the same connections to the powerlink socket of af BL3500 MK2. It looks very much like af normal powerlink connction with pin 2 in use, He is writing that he has tried it on his own MK2 BL3500.

Connector wise you almost cannot do it wrong on the TV side. The worst that can happen there would be switching left and right channel. But what about the orher end of this cable? Do you have phono connectors or DIN connctor?

in the TV setup under advanced settings there is a possibility to choos S/P DIF on/off. If it is set to on you might not get analog sound through

[Madskp]

I see your frustration when things are not working as you think it should, and then even on an old and slow computer.

my earlier experience with the Beoport was with the Windows software from B&O which I found frustrating to use. At the time I didnt have any other Masterlink products, and was used to Winamp for listening to music on the PC, so I might not have seen the benefits.

My first impression with this BM link is much better, and from your pictures Linkplayer seems to have much more functionality (not that more is always better). So im optimistic.

One advantage in my system might be that I re installed the Imac a couple of years ago for some other experiment, so its almost a new installation

[Madskp]

I now have the BM link software (v1.5) up and running with the Beoport connected and a pair of headphones in the Beoport.

I can control Itunes music play/pause/skip/next album and volume with a BEO4, so guess my hardware part of the setup is working.

I just realized that the Built in speakers in the Imac is redundant in this setup when the sound output is connected to the Beoport, but then again a pair of Beolabs can do better than the built ins anyday
