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.

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.

Dillen wrote:

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

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

Also added data in form of >> and << on the BL3500 display when using FFW and RW on the Beocord. Might be due to the newer software version on the 2026. Will also check if this is the case when used with the 1611 converter and the BL3500.

Just tried a test with BL3500 – ML – 1611 – AAL – MCL2AV – AL -Beocord 3500.

For the older type 2020 MCL2AV A.TAPE is just shown on the BL3500 display.

For the newer type 2026 MCL2AV << or >> or <> is shown next to A.tape when in RW, FF or stop mode. So it’s defenatliy something in the software of this MCL2AV that gives this information.

Thanks for the input. Will try to wire up a cable, and great Idea with and adapter, Have actually also thought of making something for easy unplugging of the IR eye on the MCL2AV boxes, so might as well make a solution that works for more units.

I have made a test with the MCL2AV that I have, although it’s unstable at the moment, so the result will have to be verified. But using the same cable that I used for the BM5500 I tried to connect the BL3500 directly to the MCL2AV’s AUC connector, and my Beocord 3500 to the tape connector of the MCL2AV. No IR eye or speakers connected to the MCL2AV. I was then able to start the Beocord 3500 through the BL3500 and play/stop/FF/RW/step forward and backward, so datalink commands was passed through from AAL to AL signals. However I got no sound through. Tried again with the BM5500 just to check that my cables were ok and it still worked. I have to get my MCL2AV going stable again or get another one, but I think the control signal part is interesting.

So after the repair of my MCL2AV Type 2020 and the addition of and type 2026 it is time to revisit this test.

Again with the type 2020 no sound, but I could control the Beocord 3500.

However trying the same setup with the type 2026 gave me sound, control. Also added data in form of >> and << on the BL3500 display when using FFW and RW on the Beocord. Might be due to the newer software version on the 2026. Will also check if this is the case when used with the 1611 converter and the BL3500.

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.

I just found a Type number 2076 on UK eBay: https://www.ebay.co.uk/itm/255750627132 From reading the instruction page in the advert, it seems to have been originally packaged with a mains adaptor and a wall unit/transceiver that also served as a charging unit for a BL7000.  I vaguely remember reading about this rare item in the old forum.

Yes it seems to be for the LCS 7000 that could also  act as a wall charger for the Beolink 7000

manuals here https://www.beoworld.org/manuals_view.asp?pid=975

But I think that just confirms that the MCL2AV got different type numbers depending on what kind of kit it was used for.

Also had a look insidd the IR eye. Some signs of corrosion, but most of it could be scrubed of with a brush and some IPA.

the item numbe on this one is 1202625 so it seems to corrospond with the type number on the MCL2AV. Also the serial number is the same.

No problem, just post again if you need more info

Perhaps like mine but packaged with EU power lead.

Oh yes things like that could also be the reason for different numbering.

Guy wrote:

I did mistakenly call mine a 2023 earlier in the thread, but I just re-checked the photo and it’s actually a 2032

Ok that also makes more sense as the type number 2023 is used for the power supply for the MCL2AV type 2020 in some of the B&O documentation.

I wonder if the difference between type 2026 and 2032 could just if the were part of and extra active speaker kit or a extra TV kit, and maybe being preprogrammed for the correct options in theses setups

Yours appears to have a screw missing at the back of the CD socket – this probably makes the socket more secure when pulling leads out

Yes, I’ll have to see if I can find some replacements as an other one of the screws is also not in a very well condition.

A little update to this thread. I just bought an extra MCL2AV, and it’s type 2026 SW 2.3. It costed less than 20 Euros including shipment, so I couldn’t resist, and then I also have a backup if the other on fails again.

@Guy: You have called one of yours type 2023 with SW 2.3 also. I wonder if its actually the same box just for different markets?

Let me know if you come up with any scenario to test out with this unit.

Ok, so it said DVT, so I ended up not buying it. But thanks again for the info, could be usefull if I find another one at a good price.

Hello again

My answer is assuming you do not have an other audiomaster product connected to the Masterlink of the Beosystem 3

chrisworks wrote:

Thanks a lot of the info and yes, I ideally would like to control the beogram with my remote. If I were to source a BeoSound Ouverture would it needed to visible to the remote or would that be handled by normal BeoSystem IR interaction? I would really like to go for a minimalistic look, basically just the BeoGram visible. Today everything is hidden away in my cellar and so only cables are run for IR and speakers.

The advantage of using datalink and masterlink is that the control signals are transmitted in the cables, and therefore you don’t need the IR eye on the BS overture to be visible, and don’t need separate IR cables. You do however need to setup the Beossytem 3 to accept both video and audio commands by putting in in option 2. With a BEO4 press: Standby + list at the same time. the press list unitil option? is shown in the display, and press go. It will now show V.opt, the press go and 2. The Beosystem 3 should now be in option 2 and accept both audio and video IR commands.

Depending on how, or if you want to use the Overture in the room it is going to be placed it could be set at different options. Option 0 it will not react to IR commands. Option 1 it will only react to audio commands, and option 2 it will react to both audio and video commands, and thereby let you have sources from the Beosystem 3 played through speakers connected to the overture if you want to do that.

chrisworks wrote:

BS3 -> ML -> BeoSound Ouverture -> DL -> Beogram X?

That is the correct setup. You might need a 7 Pin datalink extender cable if you place the Beogram and Overture in different rooms.

chrisworks wrote:

I am not looking for the most exclusive, rare, etc – just a very nice sounding Beogram. They are all pleasing to the eye, so I am less concerned about the visual differences between the Beograms.

As the Overture doesn’t have an integrated RIAA amplifier, the easyest solution would be to get af Beogram with integrated RIAA. Datalink compatible Beograms with integrated RIAA is Beogram 3500/4500/6500/7000. For difference in quality on the Beograms others might chime in. Of course you could use another Beogram without RIAA, but the you will also need and external RIAA amplifier with transfer of datalink signals.

Thanks thats a great tip.

BTW my own says FM on the label, but I think that my father might have got it without at a discount when he bought it at the B&O employe sale
