Great to have that confirmed. Just for fun I did a voltage measurement on this pin and it reads 0.4V and fluctates when a command is pressed on the remote control
SL-config is not connected to ML-sense
You can see in the schematic that SL_Config is actually an output. The “CPU CARD” can set it’s SL_CONFIG pin low which will then provide a logic high signal (5V) on PC pin 1. SL probably stands for slave. Maybe to tell a peripheral connected to the PC socket that the PC source was activated?
The original peripheral for this connection was the first Beolink PC office box, shown in one of the first posts in this thread. The ML data pins and the SL_config pin was then connected to that. But if it makes sense that the BL Active should send some kind of signal to the BL PC office box when there was also the ML data I don’t know.
But if you can tell from the diagram that SL_config is and output then we might not have much use for that for input applications
One thing I will try to test is if it will run with a BLC 1614 connected on Masterlink, just to check if a Audio- or videmoster is required, or if its just the presence of Masterlink voltage, and or signals
Tried to test the BL Active with a 1611 Converter connected as an audiomaster on the ML side just to get a baseline of things working. BL active in option 6.
All functions works as expected, I can choose all audio and video source from the ML side and get sound through powerlink, and I can use the PC input and get sound through powerlink.
Replacing the 1611 converter with a 1614 converter on the other hand will not make any functions work at all. The red standby LED on the IR eye will just keep lighted. SO no luck there
Just redid my measurements, and I must have followed a wrong trace when I did my measurements last, as there is no connection between Pin 1 SL-config and the Masterlink connector.
But still as the diagram also shows:
Pin 6 Data – is Masterlink Data –
Pin 8 Data + is Masterlink Data +This afternoon I have spent some time searching my boxes of manuals related to all the B&O converters. I have found a circuit diagram for type 1636 which is attached.
Great to have this diagram to do back up our testing. I can already see that I will have to revisit my measurements as SL-config is not connected to ML-sense (which doesn’t seem to be there at all).
Thanks for the 1636 schematic Keith!
I should also point out that the type 1636 (EU) replaced the 1611. In fact, all type 161x converters were replaced with 163x units when one was purchased. In other words if a 1611 (EU) converter failed, it must be replaced by a 1636 (EU)
I must admit that I don’t understand this! I can imagine the BL Active 1616 (two PL sockets) being replaced with Active Type 1636 (PL and PC sockets). However surely the BL Converter 1611 is used for a totally different purpose with PL and AAL inputs? Or is there another ‘EU’ version of the 1611 out there?
I am also a little puzzled about that as the 1610, 1611, 1612, 1614 and 1615 all converts between Masterlink and AAL datalink where the 1616, 1618, 1636, 1637, 1638 and 1639 all are link room products with IR and Powerlink connection + the added PC connection on the 163x series. Could it be that it was only units from 1616 onwards that was replaced by 163x? Maybe a text written in a cryptic way?
Anyway some followup testing to do with the functionality and many thanks to Keith for locating the diagram 🙂
Looking at the PCB drawing in the servicemanual the burnt spot could look like its above a diode. The diode could be shorted, but it could also have affected other components. The Diode is in the part of the circiut that amplifies the data signal
That’s a good idea – I don’t think I have a 1614 but I guess yours arrived as part of that large pile of black boxes you acquired!
Yes there are 10 of them as part of the mountain 🙂
Haven’t got any luck dealing any of them on, but then again the 1611 is a better option
I will do some testing when I have time this week. There have been unsuccessful attempts to use BL Active stand-alone in the past, such as here: https://archivedforum.beoworld.org/forums/t/31173.aspx My BL Actives are all SW1.1.
I will try that too. I have both a SW 1.1 and 1.6 as far as I remember.
One thing I will try to test is if it will run with a BLC 1614 connected on Masterlink, just to check if a Audio- or videmoster is required, or if its just the presence of Masterlink voltage, and or signals
The setup manuals for OneRemote’s latest devices just show the code to make the OneRemote respond to the PC source key, without saying whether this is received directly (IR to OneRemote) or indirectly via the PCSNUT.
It says that indirectly as it is a direct mode code.
Also the description in you manual is that it is a setup for a link room which I read as part of a link system, and therefor the masterlink signals will be in use, hence the Oneremote radio can not be an audio master in that context.
What we don’t know is if there has been some update og Oneremotes products that is not described in the setup manuals we can find.
I found this setup manual from Oneremote https://doc.oneremote.dk/Vejledninger/30012002S5dk.pdf Only in Danish though.
On page 27 it describes that it can be connected to the PC connector in all Link rooms which does not correspond with my theory about it acting like and audio Master.
However the setup is also described as direct mode which is via an IR reciever, so there might not be any data connection in place. That makes sense when used in a Masterlink system with other unit.
It does however not explain how it should be used with the Beolink Active as a stand alone unit which as far as I know does not work under normal circumstances
One other thing that intrigues me is that some OneRemote documentation implies that the BL Active can be used stand-alone with the OneRemote radio as an input – look at the ‘tip’ in the diagram below: I wonder if the adaptor cable does something funny to make stand-alone operation possible?
Yes thats intriguing. Looking at the adapter itself (PCSNUT) https://shop.oneremote.dk/shop/69053-oneremote-/4271-pcsnut-adaptor-cable/ it doesn’t seem like something special, and based on our knowledge about the ASNUT and VSNUT adapters from Oneremote they are just passive adapters.
I wonder if the setup manual describes a speciel setup code for this setup?
My best guess is that this setup could change the signals from the Oneremote radio from datalink to Masterlink. We already know it can change between the two different datalink formats.
If it does change the signals to Masterlink then the Beolink active will get a Masterlink signal from the Oneremote radio via the PC DIN connector which as mentioned earlier has its data pins directly connected to the Masterlink connector. If the Oneremote radio the work as a Audio Master it should be sufficient to drive the Beolink Active.
Hope this makes sense
And of course we still don’t have the service manual for the Beolink Active 1636

Data + So my first question before I start experimenting: Does anyone know what pins 1, 6 and 8 are for? I can confirm that these connections are correct. Data – and Data + are the differential data lines and are the same as pin 1 & 2 on the Masterlink socket. The SL_config works like the ML_config in defining direction of data.
Hawing done som continuity Measurements inside the Beolink Active I can confirm that the data pins and the SL_config Pin has direct connections to the Masterlink connector as follows, and must be Masterlink data in a DIN connector.
Pin 1 SL-config is Masterlink ML sense
Pin 6 Data – is Masterlink Data –
Pin 8 Data + is Masterlink Data +On a related subject, I do want to do some further experiments with the BL Active’s PC input at some stage. I know audio L & R go to PC pins 2 & 4 but I wondered about pins 6 and 8 and whether they could be used for datalink (or AAL) control of a local source. PC input pins as listed in this thread: https://archivedforum.beoworld.org/forums/p/15997/281594.aspx
According to Keiths post here https://beoworld.dev.idslogic.net/forums/topic/beolink-active-1636-pc-input/#post-14712 those are Masterlink data. More so I can confirm that as I have done some continuity measurements at one point where I found that there is a direct connection between the data pins in the PC 8 pin DIN connector and the data pins in the Masterlink connector. I will do an update of that other thread with this observation as I for some reason never got around to do that.
However I have also been thinking what could be don with that port, and maybe some kind of adapter to take the sound from the PC DIN and if usefull the data from a Powerlink connector as they sometimes use the same datalines as MCL/AAL connections.
Might get arround to do some more digging into that subject in that other thread
I am at my parents house at the moment, and looking into their Apple TV the remote seems to be the 3rd generation with USB-C and sw. 0X33.
It does turn on their Beoplay V1, and do control the volume. 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.
Oh yes that was the function of the ASNUT adapter from Oneremote that was discussed in the beginning of this thread.
To make your adapter/Switchbox really universal you could make data connections to both pin 6 and 7 at the input end.
Of course you might need another box of chocolates to prepare you for the extra soldering ?Nice little project for making easier to use dual inputs to the BL1611. And also the design is more interesting than another black box.
I am just wondering why you are using pin 7 as datapin on the 2 inputs? Is that what the oneremote radio is using?
For other AAL compatible connections like the MCL2AV or a Beomaster/Beocenter/Beovision the data is on pin 6.
Ok, now I understand. I thought you meant that it should be possible to have both a Beogram and the Oneremote radio connected to the BC2300 at the same time and send audio commands to both
Guy wrote: It can even use both these pins at the same time if both a Beogram and BL1611 are connected using a Y-adaptor. Yes, but not sure that you are able to use a audio source command for the BL1611 in that case? At least it’s not possible on the ouverture.
Just remembered that the Ouverture has Masterlink and the BC2300 has Audio Aux Link, so each connect a different way to the BL1611, so different setups.
However I’ am still not sure if the BC2300 will be able to send audio source commands to the Audio Aux Link Pin 6 as well as the Data link Pin 7, but it would be nice if I can be proven wrong
