Measuring IR wire when disconnected gives 0v at Essence, and 1.2V at sensor, the latter increases to approx 4V when IR transmitting.  It is behaving as if the Essence is expecting IR data on a different pin!

Yes I think your IR eyes are fine but the Essence is not putting the IR voltage out.

One thing i note when looking at the wirering diagrams for the IR eyes in the Beolink Handbook is that Essence and Core for that matter is not mentioned. I would expect the wirering to be as for the Beolink Converter NL/ML, but you never know.

I will find something else to connect the ML sensor to – maybe BL Active or Passive, and see how the voltages change.

Good idea to have the understanding of how it should work.

 

BTW. could there be a software issue with the Essence, like feature removal in newer versions og first added after ceartain software revision? Pure guesswork from here

So is the 5V at the IR data produced by the powered IR eye or does it come from the source (Essence or MCL2AV)?

I just tried to disconnect the IR data pin on the MCL2 AV. On the screw terminal of the MCL2AV I hav 4.95V. on the loose wire from the IR eye I have arround 2.6 volt. As I understand this type of signaling the tramitting part should try to pull the voltage down.

 

Where you are measuring the 1V and 0.4V could you try to disconnect the wires to see if voltage from the IR eye differes from that from the Essense?

Also when connected can you meassure a voltage around 5V between ground and IR data screw terminal of the IR eye?  No, it’s about 0.4V If yes can you see the voltage changing when pressing a key on the BEO4?  Pressing transmit shows momentary change from 0.4V to about 1V

That does not sound right. I just double checked on a MCL2AV, and the voltage between ground and IR data is normally 4.95V and drops to some place between 4 and 5 V depending on the key pressed. I have also seen this behaviour on other setups.

 

One thing you could do is to meassure on the bare ends of the rest of the wires in the network cable if any of them have a voltage arround 5V. That could indicate if the Essence has a different wirering.

I have connected exactly as in the diagram above, with just +5v, Gnd and IR data connected,

Not having any knowledge of the inner workings of the Essence I have a few thoughts regarding the cabeling, although I know you are pretty capable withe the B&O IR eyes.

• Have you used a cut over network cable to make the connection? I have seen some network cables that do not follow the standard color coding for example what comes first the white/orange or the orange.
• If possible can you check the connection between the RJ45 connector and the screw terminal in the IR eye for continuity?
• When connected can you measure 5V between Ground and +5V in the screw terminal of the IR eye?
• Also when connected can you meassure a voltage around 5V between ground and IR data screw terminal of the IR eye?
• If yes can you see the voltage changing when pressing a key on the BEO4?

 

Hope this can help you dertermine if it is an issue with the connection or the Essence itself

If I remeber correctly from another thread that I can’t find right now there is a possibility of a transistor and a diode in the datalink circuit that can fail. It is transistor TR1 and diode D5

C63 is directly connected to the data pins on the speaker 2 conections

Thanks – I’ve downloaded it ready for when it arrives. I’m using a Windows 10 PC (I’m a keen PC gamer, so Mac is no good for me!). I’ve held off on installing Windows 11 for now as it needs me to change some BIOS settings and then reinstall, and I simply can’t be bothered with all that just yet!

Great, if I remember correctly you have to run the setup as administrator for it to work

Another source for narrowing down when the button and LED was removed is to do an Ebay search for Beolink Passive and ML/MCL converter. A lot of sellers have pictures that show both the front and the sticker with the serial number.

Also be sure that the left and right speakerlink connector are in the left and right speaker 2 socket respectivly on the BM7000. One of the connectors are carrying power and the other data. If they are factory made connectors there should be left and right stickers on them.

As for the Beolink PC2, I missed out on the one that was on eBay but another will come up, and I am just too curious not to buy one now!  One thing I didn’t think of though – will I be able to get the software for it?

It is not official available from B&O anymore, but I was able to find it online on a random download site. Let me know when if you going to need it and I can supply you with it. I have i running on Windows 10 even though it is not official supported.

Not able to answer your questions, but have an input based on the Beolink Passive and ML/MCL converter I have:

My Beolink Passive has the LED and power button and the serial number is 142373xx, so from year 2000 (source https://forum.beoworld.org/forums/topic/serial-number-and-date-of-manufacture/ )

My ML/MCL converter does not have a visible LED (it is still in there and can be seen through the grill in the cabinet) and no power button. It has serial number 194461xx  so from year 2006

Hope this might be usefull, and maybe others can chime in with info from their products to narrow down the period where it was changed

There are some reel to reel threads on the archived forums that might be interesting for you to take a look at, for example this

Other that that I have almost zero experience with reel to reel

The Playmaker is working 🙂 It is missing the stand though. Could someone measure the dimension of the stand material and the lenghts of the standing and lying part? Then I think I can bend something out of steel wire. Thanks in advance

If you’re not using the masterlink port on your Ouverture you could connect a 1611 converter to it, and plug the tape or record deck into it’s aux in. You can pick these up for about £30 on ebay. The converter would configure itself as the video master, giving you an extra source on the ouverture. Whatever is plugged into the converters aux socket will then be accessible on the TV, SAT & V.MEM sources on the ouverture. Rob.

Thanks for the input. I am avare of this solution, however my goal is to be able to datalink control the 2 connected units. Therefore the specific question regarding the Y-cable to datalink AUX solution

It can be setup as s link room (option 5 or 6), but might not transmit the clock then. BTW it also need a connected running computer to work

Actually you know, there’s a very cheap Beolink PC2 going on eBay (which I believe is effectively the same as the Beoport?). Is there a way for me to have them all connected – Beolink PC2, Beolink Converter 1611, Beolab 3500 and Beocenter 8500? The Beolink PC2 on eBay has a Masterlink cable included which is split, so it can connect to two other Masterlink devices, so I’m thinking one connects to the BL3500, one connects to the 1611, and then of course my 1611 connects to my Beocenter 8500? Or am I simplifying it too much!? I’ve read that the Beolink PC2 acts as a master, so would this interfere with my Beocenter 8500?

the Beolink PC2/Beoport will conflict with the BC8500 as they have the same sources PHONO = N.RADIO, A.TAPE2 = N.MUSIC

So no that will not work

Nothing B&O is ever “completly dead”, maybe the Beosound 3 and still, not always. Correct your post unless I will have to moderate it!

Let’s call it dead on arrival then 😉

An excellent find – I am looking forward to hearing about lots of experiments with your new acquisitions, in particular the Video Link 1

I was also a little curious about that. I looks like it can send datalink signals between TV’s with datalink capability through the antenna cable, and that way a local room (I guess that means Link room in modern terms) can control the VCR in the main room. Clearly something for the MX and LX line of Beovisions, but might not be very usefull today. I will save it though if an idea pops up.

The DVD2 is a fantastic piece of engineering but just so very complicated in use – I had one for a while but gave it away free when I sold my BC6-23.  I now just use the far simpler DVD1.

It’s actually a HDR2, so again a thing that might not make much sence for modern TV’s. I will hook it up to the BC6 and test it though.

What’s the plan with the Playmaker?  (The main reason that I keep mine is in case I want to use the aux-in auto-sense to trigger PL speakers, perhaps for a non-B&O TV)

It is the autosense function I was going for, and might be primarely used in test setups

 

Btw. I have teted the 2 Beolab 3500. One is software 2.0 and is working, but the bass driveres are damaged. The other one is software 1.0. I ca not get it to activate my Ouverture, but it says ML is ok. But the SW 1.0 was also not fully working with Masterlink, so that might make sense.

As for the BC5000 it is completly dead, and the CD50 is ejecting the CD when I try to play one. It might be a small reapir.

I was in the market for a Playmaker when I stumbled upon this deal for ~150€

All untested so have to see how good of a deal it was, but there might be some working parts between. A bonus is the Beolab 3500 table stand on one of the BL3500’s which seems to be almost unobtanium

From top to bottom:

Beogram CD50

Beocord 5000

Playmaker

2 x Beolab 3500 MK1

Beolit 505

Beolit 707

MCP 6500

Beocom 6000 MK1 with extra handset

4 x MCL2AV

MVL2A

LC2

HDR2

2 x BL1000
