I think that is how it could be described. Mayby the sound is passing through some passive components instead through the supposed way through the circitry

Next I am going to dig out my OneRemote radio and see how that behaves connected straight to the 1611 and to the TV (without an ASNUT cable!) When my OneRemote was connected to my BC9500 it had to be connected to the Tape 2 socket, which uses datalink pin 7. Perhaps the ASNUT cable just moves the datalink to pin 6 for the 1611? I may try a pin 6 to 7 bridge …

I tried my OneRemote Internet Radio connected to the TV via the 1611 and it didn’t work (needs ASNUT cable!). I tried setting the radio to several different modes, both video and audio, direct and cable link. Nothing worked. I also tried bridging AAL pins 6 and 7, with no change. I may try swapping pins 6 and 7, but I really need to buy a 7 pin socket to make a lead and try that.

How much pins do your internet radio have ?

7 pins, but I think the OneRemote data is going to pin 7 which is not connected inside the 1611. Hence why I think I need to swap 6 and 7 (or use an adaptor)

[Madskp]

Found this thread from the older forums regarding the power link socket on the 1611. Seems its an input, and might give some on off functionality maybe?

what are your thoughts? The manual for the 1611 only mentions it briefly

Yes and that’s where I think B&O like to keep us in the blind…

From my diggings in the old forum, the powerlink socket is of no use at all for us. It just tell the converter when you turn up the system or change volume from the keyboard of an AAL unit like the Beocenter 2300. It carries no sound and accept no sound, just “meta commands” if I can call it like this.

That would be a very dirty trick from OneRemote.

[matador]

Ok Gentlemen,

Why can’t we (almost) not use the converter as an something-master when connected to a Beovision?

Guy succeed when using his Beosound 1 but why didnt I when connection my 2300?

Tomorrow I will connect again the 1611 with the 3500 and start it last to see if it reverts to the need of AV+key to open is AUX port. I mean, are we struggling with a lack of procedure testing or against an autoconfig devil? That will be a long night…

If you look at my photo of the underside of the 1611’s PCB (back a page in the thread) you can see that only PL pin 4 is connected. PL pin 4 is speaker on/off – as I think some of the posts in your linked thread confirm.

But my BC9500 TAPE 2 input (where I previously connected the OneRemote) needs the datalink to be pin 7, so you can see OneRemote’s problem!

I also once connected my BC2300 to my BV10-32 using a 1611, and it played fine through the TV, including the connected Beogram. (I had to use an a.aux Y adaptor, so the Beogram and 1611 shared the BC2300’s AUX socket)

Perhaps something in the ML cable tells it how to behave? Connect to a TV and it becomes an audiomaster, to a BeoSystem (or BL3500) and it becomes a videomaster.

That’s an interesting theory. Right now the only Masterlink TV I have has its plug out of reach but it worth a try.

So after staring at a 7-pin DIN to DIN cable for several hours I have made progress!

Basically I realised that the 7-pin DIN to DIN is not a crossover cable, it maps identical pins between the two devices. Thus when I connected my BS1 to the 1611, I was connecting pins 3 and 5 of the BS1 (i.e the input pins) to pins 3 and 5 of the 1611 (also what I thought were the input pins). But that had worked, so it was not logical. The BS1 was sending its audio output via pins 1 and 4, hence the 1611 must have been getting its input from pins 1 and 4.

So I just tried the iPad connected to the 1611 AAL socket (pins 1 and 4) and by ML to the TV, and I could select the iPad by selecting any audio source on the TV! So it is working as an audiomaster!

It would seem therefore that the 1611 uses pins 3 and 5 as input when it is a video-master, but pins 1 and 4 when an audio-master. This starts to explain the OneRemote ASNUT cabling, but may still not help with the connection to a BL3500.

(Luckily I found one of these cables (and a 3.5mm to twin phono socket) so I was able to test without any soldering!)

EDIT: And your BC2300 should work in exactly the same was as my BS1 because the AUX socket pins 1-5 are connected the same way.

[Guy]

And to confirm the above logic I just checked the Audio Aux Link circuit diagram for a non-ML equipped MX TV. The outputs are on pins 3 and 5.

This also explains how this sort of setup works (from ML handbook):

… because the TV can receive the Audio from the BeoCenter, and vice versa, but the BL1611 ‘chooses’ whether the TV or BC audio is being sent over Masterlink, according to the source selected elsewhere in the ML network.

Could it be as simple (and stupid) as that? I’ll try tomorrow since I have one of these 4 RCA cable too or could make one if needed.

Could that mean tant you could have two sources connected to a 1611? Say Ipad on TV and Airplay on A.AUX?

Can’t wait to go out of the bed tomorrow! Exciting progress! Thanks Guy!

Looks like my study but most of it is hidden behind the PC screen.

[Madskp]

Hello again. Very great findings, glad that it was actual more simple than it seamed. very nice to know how this can be used for other things than it was meant to be.

@Guy: Nice Beocom 6000 you have there ?

Thanks Matador,

Here is a link to a “Dual source” RCA cable that will let you use a “Video source” and an “Audio source” via the Aux input of the Beolink converter (I can supply 3.5mm minijack adapters with the cable on request):-

Kind regards, Steve.

@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.
