I feel rich now, owning a BeoLab 3500 and TWO 1611s :-). Thanks Matador and Guy!

@matador: just a suggestion for the drawing. One or both sources can still be a BEO product with datalink. The datalink pin 6 can be relevant to show on the DIN pinout drawing for this usage.

It’ll be interesting to try connecting a few B&O sources (CD player, Beogram etc) and see if they can be controlled. At the very least, some will need an adaptor to move datalink from pin 7 to pin 6.

From an old post by Peter about datalink pins:

Tape and CD use pin 7, Phono uses pin 6 except when the record player has a built in RIAA when it too uses pin 7. However TV/AUX uses pin 6 as well just to complicate things.

[Madskp]

That is also what I have found out looking in several service manuals for older B&O products. The MX and LX Beovisions (and probably others) has datalink on pin 6, and audio out on pin 1 and 4.

As mentioned earlier in the thread I wanted to try with a Beocord 3500, but when I saw that both the audio pins and the datalink pin needed to be moved in postions i postphoned it. I will try to make a converter cable one of the comming days and repport if that will work.

I am considering making a little junction box with two 7 pin DIN input sockets and switchable datalink pins.

You could actually modify a BL1611 and turn the PL socket into the ‘Audio In’. You’d just need to disconnect pin 4, and then run internal jumper cables from PL pins 2, 3, 5 and 7 to AAL pins 2, 1, 4 and 6 respectively. It could be quite straightforward but I don’t like modifying original B&O eqpt, so I think the external box would be better, and more flexible if the datalink was switchable.

Et Voilà,

Thank you a thousand times Guy for your constant tries, everlasting curiosity and sharp ability to dig into any white paper.
Thank you Madskp for joining us and giving some clues that made us going forward.

This morning I tried this:

Converter 1611 turned up on first (I am maybe superstitious on that one) connect to the Beolab 3500 via Masterlink.
On the AAL socket on the converter, I have that adapter I use to convert DIN Line In/Line Out to 4 RCA from a Beomaster, 5 pins, I’ll check and post the exact wiring later.
Each pair of RCA connected to an iPod with a classic RCA to Jack Adapter.

And…

Audio sources (CD, A.TAPE, RADIO… AND PC) trigger iPod A,
Video sources (CDV, V.TAPE, TV…) trigger iPod B.

So, we now have a standalone Beolab 3500 with to remote switchable channels!

This is Beoworld!

Here you have:

Great news Matador – I am very pleased that it all works! To be honest when I discovered the Pin 1 and 4 audio-master trick I didn’t then consider a double/selectable source, and so straightforward to set up and control in the end!

I think that together we have doubled the value (and second-hand prices!) of BL1611 Converters, and probably BL3500 as well. I assume that the same would work with BL2000, and possibly also if the 1611 was connected to a Passive (with IR eye) – I might try the latter at some point.

Great diagram too – it looks like it comes from an official B&O manual! Maybe add a note to say that the BL3500 is in L.OPT 6.

(Actually, is it me or have you got the Audio and Video Beo4 sources reversed in the diag? Pins 3 and 5 (video source) were on the right hand side – source B.)

Also, have you tested what source (A or B) the PC command selects, if any? Some users may want the double setup in a study with their computers, and it would be good to see PC on the source display, if it does that.

Anyway, have a great day all!

Actually that was my main concern before posting, since I still need a second converter. 😀

Done.

They were reversed, corrected now.

Channel A (Audio side) can be triggered with a PC command. Beolab will display “PC”.

I’ve just seen the diagram corrections thanks, and good news that PC works too.

I have just tried the ‘double source’ with the BL1611 connected to my BeoPort (connected to Win PC) – there are no other ML connections. I put the Beoport in Opt 6 and added an audio source (RADIO) and video source (TV). I can select these using individually using the on screen remote or Beo4 – it’s very useful indeed to have the two additional analogue inputs:

[matador]

There is a Beoport around for not too much. I’m still hesitant to take it since I’m a Mac guy.
But after today, who knows how much fun we could have with it!

I know they’re is a driver for Mac Called BM-link that still can be found but it seems it was another one a little bit better and this one cannot be found anymore. That stops me.

Good it helps your setup Guy.

Cheers and again, thank you for being partner in crime.

A pleasure – it’s very satisfying to get it all working with a bit of long distance international teamwork!

I’ll probably do some more OneRemote/1611 testing (making my own ASNUT cable) and maybe 1611/Passive/IR as well, but may well start a new thread depending how I get on.

I am not sure that I would get a Beoport if I didn’t already have one. I suppose it’s quite useful in a stand-alone study system with Beolab speakers, but now you could just have a PC connected to a 1611 and BL3500, with less cable mess and a spare analogue input!

Please, name it differently!

[Guy]

For amusement, here’s the Beoport/1611 test rig!

 

[matador]

Who said B&O was all Look over substance? 😀

[Madskp]

Now I tried making a converter cable moving pin 3, 5 and 7 to 1, 4 and 6 and connectiong the Beocord 3500. Sound is going through. fine, but no controls via datalink. It might be that at Beomaster/Beosund has to be between to translate the signals.

But as a bonus I couldent resist to try something with the powerlink conenctor on the 1611.

I don’t have a beomaster with power link on hand, but since its only pin 4 (and 7 and 2 to ground) that is connected internally in the 1611 I made a cable where i could inject voltage on pin 4 and 7.

With the Beocenter 6 and 1611 connected via ML the TV turns on and are on and audio channel when I apply 3V to these pins, and I can play music through the AAL din on the 1611. When i turn of my 3V source the sound will stop, but the TV will stay on.

If the TV is on and on a Video channel to start with I got no reaction from applying the 3V.

So the Powerlink connecter might be usefull for some scenarios, dependent on how it reacts connected to a beolab 3500/2000/active

This site https://github.com/toresbe/datalink explains why I cant use the Beocords datalink with the 1611, as there are two versions of datalink, where one is between components in a stereo system (Beomaster, CD,tape etc. and the other is between systems, beomaster to 1611 or beovision with datalink. Also this seems to be the reason pin 6 and 7 vary although I cannnot see why a Beogram is not communicating on pin 7 like a CD and tape player. If I remember correctly something was mentioned in one of Steve’s videos about CD and Phono commands being the same. That could explain why the are on different pins.

[Guy]

Very useful experiments – thanks for sharing!

I didn’t think that PL pin 7 was connected to anything inside the BL1611. I presume that you were trying to use it as ground in conjunction with pin 2, or instead of?

Interesting. This may explain why my OneRemote Radio has a different 3-digit option code when connected to BL1611 to when it is connected to BC9500. (Eg to activate with N.MUSIC on my BC9500 it needs to be set as ‘302’ and with a BL1611 is needs to be ‘402’). I haven’t tested this yet as I need to make up a converter lead to move data to pin 6.

Madskp wrote:

… but a Beogram with RIAA does use pin 7 apparently. Thus if I connect my BG6500 (with RIAA) to the PHONO socket on my BC9500 (also with RIAA) the mismatch between data pins stops me from activating the Beogram and using a double-RIAA setup.

I remember this too – was it the video about controlled 15 Beograms from you bathtub? (I may have exaggerated the number!)

I found the video here: https://youtu.be/lWGir5kAVsE&t=7m15s

Although Steve states that the CD and PHONO IR codes are the same, I think he actually means that the datalink signal that results from pressing CD and PHONO are the same.
