Ok many things going wrong it sound like, but it may be related to one single thing.
To get a better understanding of your system I have made this little sketch. SOme og the things I am unsure of is the role of the television you mention and if the Beolab Pentas are connected to that. or to the Beomaster 7000?
The black box you do mention is called a Beolink converter probably type 1611.
If my assumption of how your system is connected is somewhat correct I will suggest that you try to isolate the problem. I think we should not take the CD player and PC connection into account at first as these problems might be affected by link issues.
Before every step power off all components in the system to avoid anything breaking in the proces:
- Disconnect the the Powerlink wire between the BM7000 and the Beolink Converter. This is only nessecary for certain situation and testing what is wrong can be done without it, so better leave this disconnected. Verify if the problems persist?
- Disconenct the AAL wire between the BM7000 and the Beolink Converter do the Bedroom, Kitchen and Pentas work now?
- If not now disconnect the MCL wire and connect the AAL wire again and see if the BL3500 and the Pentas work now?
Some years ago, mice had gnawed the wires in the attic, and I had a technician from B&O over to solder that and check the system
This could of course also cause problems if there is a new problem with the wirering, but lets start with isolating the problem
My Playmaker let out the magic dmoke one day. Turned out it was one of the filter caps in the power supply that exploded
It smelled a lot like smoke and the smell was not gone before a week. I can still smell something inside it.
Today I replaced both filter caps snd it looks like it is running again
Just did a wire up of a MCL82 box with IR tranceiver and the MCL-Beolab kit.
I set the jumper in the MCL-Beolab kit to 8V as the other option of 5V did not give enough power to the MCL82, so also the role of the MCL-Beolab kit is to power the MCL network. As I only have a Terminal 5000 remote i set the switches in the MCL82 to Beomaster 5000
So what I can do is to activate the speaker relay in the MCL82 box with the speaker button on the tranceiver so the relay part is working. With the remote all buttons except mut seems to active the relay to active, and the mute button will turn the relay to inactive.On the MCL-Beolab Kit I can measure that the data signal from the MCL82 is dropping in voltage when a button is pressed, and also on the pins for the IR diode I can see a little drop in voltage when a button is pressed, so it is probably working.
I wonder why all button presses except mute makes the speaker realy go active but of course the terminal 5000 remote was not intended for use with the Beolab MCL kit, so with the right data connection to a Beomaster 5000 it might react different.
I do not have anymore ideas for testing it right now as I do not have any of the other remote types and/or music systems for this to work with. I still have it wired up so can try to test something if you have any ideas
I hope that I’m not hijacking your thread. If so, I’ll “cease and desist” and maybe start a new thread.
Very ok, and also very relevant to the subject 🙂
My (likely incomplete) understanding is that it just supports a subset of the remote commands that are relayed via a IR->wired->IR chain
Yes something like that as the BM 6000 and 8000 does not have any data communication for link rooms, so the MCL-Beolab Kit with an IR sender is needed to activate and make control commands to the Beomaster.
The documentation that I’ve found isn’t exactly clear and concise. I’ve found this old thread, https://archivedforum2.beoworld.org/forums/p/14327/126573.aspx which answers some questions.
I have also looked into that thread and there seems to be some confusion which I can understand as the document about the code converter not is 100% clear in relation to product names and numbers.
It looks like the port for the “IR eye” is a simple 3.5mm jack. If so, do you think that a generic IR emitter would work? It seems possible if all it needs to do is pass IR commands into the BM8000.
I think it is actually a 2.5mm jack and probably only with two pins (I will look further into that). I do no have that much knowledge about IR emitters, if they have to be for a certain frequency. The Code converter manual mentions a cable with mini plug and a blue LED.
Could the box be the “code converter” mentioned in the old thread?
Pretty sure it is not. The code converter do have more connectors. Having looked deeply into the code converter manual I am almost sure the box I have is the MCL-Beolab kit.
To my best of understanding this is how it works:
The Code converter can make it possible to use a Beolink 1000 to control the mentioned systems. If used with a BM6000/8000 a IR emitter has to be connected to the code converter to get the control signals to them. This can be done with or without a MCL30/82 link system
The MCL Beolab Kit is used to get data control signals from MCL82 or MCL30 link rooms into a BM8000 or BM6000 as none of them have the MCL data connection.
The Code converter ad the MCL Beolab kit can be used in parralel as I read, and that is what is shown on a drawing in the code converter manual. This way the main room can be controlled with a Beolink 1000 and the link rooms will still use the relevant remote intended for the Beomaster.
I have tried to isolate the code converter part and the MCL Beolab kit part here with the code converter in the red box. The green line indicates a connection to MCL rooms when the code converter is not used.
Hope this makes sense.
I might try to hook up a MCL82 link room unit and the MCL-Beolab kit with a LED connected to see if remote commands are passed through to the LED.
So what I can do is to activate the speaker relay in the MCL82 box with the speaker button on the tranceiver so the relay part is working. With the remote all buttons except mut seems to active the relay to active, and the mute button will turn the relay to inactive.
