Good conclusion – if I do try anything similar with the BC9500 as a source I’ll post it here, but it’s only really the ‘timer’ functionality (with rectangular sensor) that may be worth testing. I vaguely remember having problems trying my BC9500 with a BL1611 and Passive many years ago but can’t remember what sensor I used. Performance may be related to the SW version of the BC9500 source of course, so I’ll check the config tool to see if there are any relevant notes.
Always great with extra input if you find the time for it.
It may be worth deciding terminology/names when talking about IR eye/sensor types. I tend to think of the four main types as follows: – MCL sensor (normal rectangular type with Timer and Mute buttons – 5 connections hard wired) – VX sensor (as MCL but no buttons – 3 connections only to 3.5mm plug) – ML sensor (normal round type with Timer, Vol and Play button – 5 connections – usually via 7 pin DIN) – BS3 sensor (as ML but with no button markings – 5 connections possible but only three used to 3.5mm plug)
That is a really good idea, also as it seems like type numbering of MCL IR sensors seems to be the same as the MCL boxes, and therefore can be more confusing to use.
I once had an IR sensor for BM5500 with a 6 pin DIN plug. It was looking like the VX sensor, so it might be the same type, but with more connections.
Looking forward to the new thread! I expect experimentation with all the above sensor types and full MCL/ML/NL integration – just think of the number of permutations once you add in Converter configuration settings!!
Yes that’s what I am going for. Gonna be lovely keeping track of settings. Might also end up in a big cable mess 😉
PS: It could be worth getting hold of some of these if you do want to try different sensors: https://www.amazon.co.uk/PENGLIN-Terminal-Ethernet-Extender-Connector/dp/B0BTYH9726
That’s an interesting solution, I might have the parts for making something like that myself. Thanks for the inspiration
Hello. No knowing if it is possible to modify the internals another idea comes to mind.
If you do not have the BS4 connected via Masterlink to a Beovision TV this solution should be possible:
Connect a Beolink converter type 1611 with a Masterlink cable to the BS4. you can then connect a audio cable with 5 Pin din plug (audio signal conncted to pin 2, 3 and 5)in one end to the AAL connector on the 1611.
The BS4 should be put in option 2, so it can receive both audio and video commands.
With a Beo4 remote, press Standby button (the red dot) and List at the same time. Press list again until option is shown and press GO. press list until A.opt is shown. Press 2 and Go
You should then be able to activate the input on the 1611 converter with any video command (TV, V.MEM, DVD etc.)
In conclusion my BL Passive / Ml-MCL converter seems to work for all functions 🙂
Next subject is my new NL/ML converter, and I probably will test the IR receiver with that also, but thats for another thread
On the setup with the MCL2AV pressing the play button on the round IR eye again will activate the Beolink passive, but not the BC3500.
Did this test again, but this time with the MCL2AV type 2026 with the newer software.
This time it will reactivate the BC3500 when the play button on the IR eye of the BL passive is pressed, so functioning as described in the manual and as it is when used with the BM5500.
So it seems the newer MCL2AV software version functions better for this setup

It has also been a while, but yes the same setup just with the passive instead of the BL3500
Madskp wrote: I can control my Beocord 3500 through 1611 + MCL2AV (with no IR eye) Sorry a further question from your earlier post: How exactly is this connected – and where does the Passive fit in?
Hi again it’s connected like this:
BL Passive – ML – 1611 – datalink – MCL2AV – datalink BC3500
Going back a few posts, it’s interesting about the functionality of the extra two wires on the rectangular IR eye. Being required for two-way IR would make sense, and potentially for the ‘timer’ function. I suppose that just because the timer light goes on, doesn’t mean a message has been sent to the Passive via the IR data connection – the IR sensor may still need to be interrogated by the system before the Passive responds to a Timer event.
Agree about the timer function not nesesarely working just because the light is on. I don’t think I can test that as I don’t have the MCP 5550 to program timer settings.
However If you take a look at the diagrams for the MCL2A only the yellow wire is in use (for the speaker on/off circiut), and on the MCL2AV the yellow and the grey wire seems to be connected on the screw terminal (will have to double check that on the actual unit), so a little in doubt about the actual function of them
Yes its the play button I meant. But as mentioned the behavior is not as stated in the manual
Ok, I might have to correct myself. Reading the instruction manual for the Beolink Passive again I can read that a press on play should turn of the passive, and a press again should activate the last played source, and that is working as it should when the BM5500 is used as Audio master.
So the Round IR eye is working as it should even thought it does not have the text and symbols on the front.
I think I just confused myself with the result of how the rectangular IR eye worked.
But the Mute button will put the whole system in standby with a single press regardless of the two setups.
So is the (round sensor) ‘Mute’ button actually the ‘Play’ button, or am I confused? Here’s the front of a normal ML sensor:
Yes its the play button I meant. But as mentioned the behavour is not as stated in the manual
Yes it is probably the same one for a group of different products, but with different wirering and button front.
Of course there is the mute anomily but I wonder if that could be related to my Audiomaster not being ML, and/or new enough software version. It was the type 2020 MCL2AV I tried with, so might also try with the newer on to see if the behaviour is any different.
His connection drawings is inded great for inspiration, and will hopefully continue to be.
To his credit many of them show up in google picture search even when I search in english.
I did not know him only followed his thread when he had one in the Nordic forum here on Beoworld.
May he rest in peace
23 April 2023 at 12:30 in reply to: The Future of BeoWorld Membership Levels – Your Thoughts? #45911Hello Lee and Keith
Im fine with the idea of reducing the memberships types to two, maybe it will make it more transparent what you pay for. No great ideas for naming.
I think it could be a good idea to have information about paying membership benefits presented up front, so it’s easy to see what you can get by paying, and prefereable also on the forum pages as a lot of people may not get to the forum by the main page but by Google.
It could also be worth to make mention that it is not only about benefits, but also the support of running Beoworld and keeping it alive.
I think someone mentioned it in the other thread, but I also think that a visible donation button on both the main page, and on the forum pages with a note about supporting Beoworld could be a great idea.
An other idea for added benefit for paying members could also be acces to unofficial solutions developed by the users. As an example of that is Matadors exelent diagram in this thread https://forum.beoworld.org/forums/topic/beolab-3500-and-1611-converter-settings/page/4/#post-14017
Of course that one is out in the wild, but I am working on something alike to document other solutions from that thread. This way people can choose not to pay and find the solution the hard way by going through the thread, or pay to get a nice and easy understandable (hopefully) page where it’s all shown.
Let me know if that is something that could be interesting?
Great idea about the hard copy manual’s. There will probably be something interesting in that archive.
Tried to disconnect the yellow and grey wire SCL,I2C and SDA,I2C in the round IR eye.
All remote control functions still working, but no lights, and no button functions working, so thats what they are for in the round version.
I also remembered I had a round IR eye that is used wtih my Beoport without any markings on the buttons. Will try to connect that and see if that also works.
Tried to wire the round IR eye up today with all 5 wires on it. Tried it with both the 1611-MCL2AV-BC3500 combination and also with 1611-BM5500-BC3500.
All functions from the remote works. The volume control buttons on the IR eye works, The timer button turns the red light on. The play button will put the whole system in standby with a single press regardless of the two setups.
On the setup with the MCL2AV pressing the play button on the round IR eye again will activate the Beolink passive, but not the BC3500.
Doing the same in the combination with the BM5500 will also reactivate the BC3500 as described in the manual (start playing the last source that was used)
Assuming it is Beosound 3000 you mean?
The pin numbers are correct for AUX input, and that is the case for all B&O AUX inputs, so that should not be a problem.
what is your AUX source? A mobile device usually has to have the volume turned up to max for the best result.
just to be sure, have you double checked that you have connected the cable to the AUX connector and not a Powerlink connector?
regarding the remote button you should be able to use A.MEM or A.TAPE depending on the model of remote
Ok, took some time to get here, had resolder some adapters to get hold on some 7Pin din connectors that wasn’t nessecary where they was used.
Tried hooking the rectangular IR eye from the MCL2AV up with just the three wires for ground, 5V and IR. And it’s working.
I can control my Beocord 3500 through 1611 + MCL2AV (with no IR eye), the mute button on the IR eye works, and holding it in for a couple of seconds make the system go to standby. The time butto makes the red light turn on, so I suppose this function will also work?
Tried hooking up the 2 remaining wires, but had no effect on the functionality from what I could test. I wonder if they only are for 2 way functions?
I also remembered I had a round IR eye that is used wtih my Beoport without any markings on the buttons. Will try to connect that and see if that also works.
Hello again
Another NL/ML converter showed up today at a local seller for 160€. The seller could tell that he hd used it himself recently in a larger system setup by a local B&O dealer, so I was not that afraid of the SW. version. At home now testing it, it has the newest SW onboard.
So n ow it’s time to play with this little box 🙂
In the OP, your first schematics are for Beogram 1800 (= Beogram 2000 but no datalink), and the next is for Beogram 2000 & 5000.
Ok it seems like the IC on the diagram for Beogram 1800 in the start of the servicemanual is a COP 410 where the diagram for the RX2 in the end of the servicemanual shows a ETL 9410 N. But other than that the two diagrams look very similar.
The RX-2 schematics shown in the same manual is wrong. It should’ve shown RCA plugs.
Yes I also see now when looking at pictures of the RX2 that it indeed has the RCA plugs.
Thanks for pointing it out.
The Beogram RX and TX (R for Radial. T for Tangential) models were intended primarily for customers having a non-B&O receiver/amplifier. They have twin RCA plugs from factory and none of them have datalink support. Martin
ok, but the diagram in the servicemanual shows the 5pin plug, but that might just be how it was shown on the diagrams at that time
Volume control seems a little unstable, but I think I have narrowed it down to the units not responding if I press the volume button to fast repeadetly , thus skipping the actual volume steps., but will have to look more in to this.
This I never experienced with the setup with the 1611 involved. Might have to do with the unoficial combination of communication protocols between the BL3500 and the MCL2AV
