MadskpGOLD MemberThere are some pretty inexpensive logic analysers available. Search on Amazon for 8CH logic analyser. Should be more than enough for anything that might get send on the Data Out pin.
Found one on Ebay and ordered it. Should be nice to have for things like this

MadskpGOLD MemberAny idea of your parents’ BS1 SW version?No, did not check that. Will do next time I am there.You can also try to measure voltage on pin 6 and 7 on your devices just to see if you also have the 5V on pin 6Location: Denmark
MadskpGOLD Memberbut it could be an interesting test nevertheless.
Indeed
Perhaps we should try connecting the BS1’s Data + and Data – to a Masterlink device Data in/out (pins 1 and 2) and see what happens? If I am feeling brave I could try it with my BV10-32, but I wouldn’t know what to connect to the ‘ML sense’ pin 3.
Maybe not a good idea as the Masterlink data is something like 0.25V and I measured 5V in one of the pins on my parents BS1. But maybe @B3OHACK3R can elaborate on that

MadskpGOLD MemberHi again Sorry – I might not have been clear on my earlier post. I wonder the a Beoceter 9500 could be used as the slave unit instead of the Beomaster 4500? Thanks Alan
No unfortunately not. The first software versions of the Beomaster 4500 is the only units I know that are able to get the right option settings to works as a slave unit.

MadskpGOLD MemberHi Your examples are great – really helpful – thank you. Your 8th .pdf shows a Beomaster 4500 in a link room connected with a special aux cable – I assume this works as a slave unit only. Would this setup work with any other audio products that would normally be an audio master, eg Beocenter 9500? Thanks Alan
As far as I can tell it should work with other Audio master also. However there might be limitations since B&O never made it official. Note that it will only work with an older software revision on the Beomaster 4500.
In this other thread https://forum.beoworld.org/forums/topic/beosystem-4500-option-settings/#post-24550 I have tested it with a direct connection to a Beocenter 9300 with the crossed cable.

MadskpGOLD MemberI ‘won’ a spares-or-repair BeoSound 1 (my second!) yesterday on eBay, and collected it to avoid the risk of damage in the post. The listing stated that the CD player wasn’t working, so I was quite looking forward to stripping it down and attempting a repair.
Nice one, But now you will need an extra room for that in your new house 😉
Strangely I can’t help being disappointed that it wasn’t more of a challenge to fix!
Yes sometimes some of these fixes are just a matter of disassembling and re assembling. I have sometimes bought an item on the assumption that it wast just a matter of turning something on or adjust something, and been lucky more than once with that strategy
Location: Denmark
MadskpGOLD MemberNow that I have my second BeoSound 1 (see here), I wondered if it could be worth making a 7-pin DIN ‘crossover’ cable and joining the two together. Thus ‘audio out’ would become ‘audio in’ in the second, and more interestingly data-out would connect to data-in and vice versa. I don’t have time for the next few days but it could be worth a try!
I a pretty sure that the audio part will work, but more interesting if the data will.
For one thing which commands should be used? But you could try something like Link + CD or AV + CD.
Another thing is that it can only be set to option 0 or 1, so no way to select which is a link room. However if this is/was an attempt of a new type of link system, the role definition might not be the same as in the older systems

MadskpGOLD MemberIf I get a chance this week I will connect my OneRemote radio to my BS1 aux and do some further tests using my adaptor to switch data between the two pins, plus trying the OneRemote in ‘AAL’ mode as if connected to a BL1611 (I don’t think that I tried that before).
I experimented with various permutations of settings yesterday. I tried the OneRemote radio in various different cablelink ‘modes’, both for normal datalink and AAL and tried most of the source triggers (incl video, audio and PC). Each mode was tried with data to pin 7 and then separately to pin 6. There was no response in any of these setups.
Thanks for taking the time to test this. I think we can begin to rule out datalink as the format for this data in and out connection if it is actually active
Location: Denmark
MadskpGOLD MemberI think no audio master ever implemented Powerlink data Rx. I’m still wondering what they had in mind for it.
My best guess as also noted in the Beolink Active thread is for use with the ML/MCL converter where powerlink to MCL is also possible as shown in the ML/MCL user manual. For this sceneario commands from the link rooms has to be recieved through the Power Link connection.
However it might not work / being fully implemented on all Powerlink products, and definitely not the Beolink active as I tested in that other thread.
I guess it might have been a kind of a transitional feature when Beocenter/Beosystems/Beosounds began not having built in amplifiers to keep backwards support for the MCL link systems. However as soon as ML became standard in the music systems this feature might have been kind of redundant.

MadskpGOLD MemberBS3000 also has no datalink but shows ‘DL’ connections to pins 6 and 7 in the circuit diagram: Specification pages state pins 6 and 7 ‘not used’ EDIT: But for the BS3000 the manual does also say ‘N.C.’ no connection where it joins the microprocessor interface PCB.
Might be something like the BS9000 where the Plug PCB is prepared for the feature, but the functionality not implemented in the end for some reason (cost, time, etc.??)I think there is a mistake in the schematic.That would not be a firstSo probably those pins are a hidden microphone input for recording something on tape.
Yes that feature also seems likely given that the Century could record on tape
Location: Denmark
MadskpGOLD MemberAlso interesting regarding pin 6. If you connect it to ground it will unmute the analoge output on that connector. Haven’t seen that before on other devices.
I could have used that knowledge 23 years ago where I wanted to connect some extra speakers to the Century I had back then 🙂 But interesting that also the user manual says that the AUX on the Century is input only and the specssheet in the servicemanual also says pin 1, 4, 6 and 7 not connected.
I am wondering if it was developed as a way to connect a set of headphones with a special DIN connector as the first generation of the century did not have a headphone jack, but did not end up beeing official in the product.
Location: Denmark
MadskpGOLD MemberJust remembered that the Beosound Century that also does not have datalink.
It has the connections in the DIN connector for PIN 6 and 7 are wired like this:
G31 ends at a pin on the MCU called TEST. Could it be that the Beosound 1 had a similar circiut?
Location: Denmark
MadskpGOLD MemberInteresting that they actually routed it to the MCU on BS1. What confuses me a bit is that they are marked with “IN” and “OUT”. Datalink is bi-directional / half-duplex. So there are no separate signals for in/out.
Yes thats a little odd that it is separate IN an OUT. Off course the diagram is only a Block diagram so does not tell the whole story
Could also be that it’s an undocumented service port.
That would make sense in that is undocumented, but on the other hand shouldn’t it be mentioned in the service manual of all places.
I have no BS1 unfortunately but you could hook up an oscilloscope to see if there is being some data transmitted.
I have no oscilloscope at this point, but might end up getting one and see if I can learn something by using it 🙂
Location: Denmark
MadskpGOLD MemberOh yes I can see that now. Thanks for info
Location: Denmark
MadskpGOLD MemberStrange that the data connections are shown in the service manual. Perhaps they are disconnected internally and/or the software was never made compatible. If I get a chance this week I will connect my OneRemote radio to my BS1 aux and do some further tests using my adaptor to switch data between the two pins, plus trying the OneRemote in ‘AAL’ mode as if connected to a BL1611 (I don’t think that I tried that before).
Thanks for joining in. That would be a good test to indicate if something is ticking
Location: Denmark
MadskpGOLD MemberGreat info. Think i has been mentioned now and then, but with reference to the same IR circiut in other products and that it was the blank/shiny caps. So great with actual reference with values.

However the volume function seems to be stuck somehow so it will keep turning up the volume even if I turn of the TV volume functions in the ATV settings. I will have to look into a way to reset the Siri remote to see if this behavior does continue.
That’s strange – but if you can’t reset it and it’s less than a year old them you should be able to raise as a fault with Apple and get a replacement.
I’m at my parent again and have now tried to charge and restart the SIRI remote as described on Apples support pages. Now all functions seems to work, although I don’t have the same posiblities to do long time testing . I have nothing to add to GUY’s observations.

MadskpGOLD MemberBS9000 has no datalink on the aux connector. But the powerlink connector has data (DL86?) on pin 6. What do you think ?
I am not sure the data connection i the Powerlink connectors will be of much use depending on the goal.
If it is just to get an extra AUX input without datalink Usecase 6 above https://forum.beoworld.org/wp-content/uploads/2023/12/Beolik-Converter-Usecases-6.pdf can be used.
If it is to be able to control a B&O record player or tape deck it may require to set the BS9000 in opt. 5 or 6 (as a link room) and via Masterlink connect to a Beolink converter 1611 and the via datalink to a Beomaster 3500/4500/5500/6500/7000 or a MCL2AV (in option 0 or with the IR eye covered) where the record player and/or tape deck is connected. It should then be possible to use theses source with a LINK + PHONO/TAPE command from the BS9000

MadskpGOLD MemberExcellent work – you must have kept comprehensive notes from all the testing that you have been doing, and it’s great to see it presented so clearly!
Actually my notes was mostly the thread and in my head. Although I had to do some retesting when I began making the drawings as some questions regarding specific option settings and details like that arrised.
In the New Year I will have a more comprehensive look through all the combinations, but I really should prioritise looking for a new house to buy so I can settle down and use some of these setups for real.
Hope you do find a place with lots of extra rooms to enjoy your collection of B&O gear. You may need a seperate room just for your Beolink 1000 and BEO4 collection ?
Many thanks indeed for putting these together for the benefit of all!
No problem. Been meaning to do that for a while now. Also makes it easier to explain these unofficial setups to others
