Hi,
i have one of these and really have two questions if anyone can help answer?
1. Does anyone know the protocol between the Beosystem 4 and the Beovision 12? Previous Beosystems used RS232 9600 8,n,1 - but I can’t figure out what this one is as I want to spoof the BS4 to think it has a BV12 attached
2. As I can’t communicate through this connector, I’m using the IR to send a Samsung On/Off command you the monitor. The issue I have is that the IR signal is sent quite a bit of time after the BS4 starts up, so the curtain opening and B&O logo aren’t shown. Is there a way to get the IR signal to be the first thing sent?
thanks in advance
I solved this problem using a Logitech Harmony control...you have a lot of flexibility to change sequence and add delays in the IR signals.
Have you gone into the system settings to adjust the timings? I wasn't aware that there was a B&O logo in regular use. I've only seen the logo when powering up after a power cycle.
Yes, I’ve tried the timing, but it seems that the IR command comes after the power link signal is sent - and I can’t see how to change that.
if I could understand the protocol for the cable connecting the BS4 to the BV12, then I could re-engineer a solution.
I use a Samsung tv with my BS4 and I always see the electronic curtains. I don't see a B&O logo, though. I don't think there's supposed to be a logo except when the BS4 is initially powered on.
BTW, I have an exceptionally long delay for the electronic screens so that the timing is perfect if I ever go into Cinema mode and then return to the TV out of Cinema mode.
I’m actually using a LG screen, so I use a raspberry to translate the Samsung IR to a signal injected through the HDMI cable (HDMI-CEC). Ideally, I’d like to understand the protocol in the BV12 - but the service manuals etc don’t describe what it is - I was hoping it was serial (like the previous BVs using Panasonic protocols) but that doesn’t seem to be the case.
Look for beovision 12 tech reference. The Beosystem 4 is described in there - in fact it is pretty much all the guide!
here’s one:

My AppleTV 4K works OK with the AppleTV 4 PUC. With regards the Sony TV, you can send them the remote and they code it and send you the file. That’s how I got a Freesat STB working.
I've been really surprised that there aren't more TVs in the PUC database for the Beosystem 4. I've found that Samsung is pretty consistent about using the same codes for on/off so I've always replaced my screen with another samsung screen when it's been time to upgrade. I just take the old screen's remote with me to the store to make sure it will control the new tv on/off. The big drawback with Samsung now, though, is that it does not support Dolby Vision. For my next tv, I might want to look for a Sony or LG if it's in the PUC database.
Didn’t cost anything except postage to Struer.
There is a LG TV PUC in the database, but I use HDMI CEC with a raspberry to turn the TV on and off using LIRC to get the request from the Beosystem to switch. I would like to find a way to speed up the switch on as the screen always comes on later than the audio. I could try experimenting with getting the request directly from the IR Eye - just haven’t got round to it.
Hi
I've used the Raspberry with LIRC directly connected to an IR eye via GPIO.
Used it for a different purpose but this should work for you as well and you should be able to turn on your TV with no delay at all.

I plan to use a lg oled g1 with my beosystem 4.
I am currently using a beovision 9 and I have exchanged the beosystem 3 with the beosystem 4. (with the exception of the motor-stand - which unfortunately only works with the beosystem 3) - I also have a projector with a screen running via a 2nd screen setup (atlona AT-HD4-V42). in addition, everything is integrated via a beoliving intelligence)
Yes the LG-G1 is 55”and the bv9 is 50” – but it will fit in the case of the beovision 9 an with a bit of luck the visible screen-size can be adjusted with the 4-way zoom function of the lg-g1 – (is my guess and has to be tested first)
The first step is to integrate the LG-G1 only with 1080p from the bs4. (a 4K solution and redirecting the sound to the bs4 is a future consideration)
the question is how do I control (on/off) the lg g1 oled with the beosystem 4?
1. with the puc of the bs4. LG 98UB9800 is the only tv-puc from lg in the bs4 (from lg). Are the ir-codes for ON and OFF the same as that for the lg G1? Or can I use a puc from a lg blu-ray player? The puc is sending approximately 10 seconds before the curtains open. So I think enough time to warm up the lg g1. further advantage: suitable control and timings in the cinema 2nd screen setup.
2. as in the first point but, if the puc from the LG 98UB9800 is not with the lg-g1 compatible: ir-code translator as ir-trans or lintronic.
3. with the beoliving intelligence with the LG webOS TV – driver and a trigger state update from the bs4 like source name. this trigger will come a little to late and so the curtains will not be seen. Timing for the cinema setup must be set in the bli.
I look forward to inputs and the discussion.

Doubt you can squeeze a 55" into the BV9 cabinet.
I've made screen replacements in the very similar build BV5 and the MDF cabinet will 'eat' the first inch of available space behind the aluminium frame/bezel.
Never the less ... interesting project ... Looking forward to read about your progress ... 👍
I'm finally did it. my BV9 has now got a LG-G1 evo 55 oled upgrade.
I am currently using a beovision 9 and I have exchanged the beosystem 3 with the beosystem 4. (with the exception of the motor-stand - which unfortunately only works with the beosystem 3) - I also have a projector with a screen running via a 2nd screen setup (Atlona AT-HD4-V42). in addition, everything is integrated via a beoliving intelligence)
The LG-G1 is 122,5x70,6x2,31cm and the space in the BV9 is 122,8x73,6cm (visible through the frame 113x65,2cm) so the new LG screen left and right each covered 4cm and above and below around 2cm through the frame of the bv9. most of the time the films also have black bars above and below and therefore not a big topic for me. (Unfortunately, the 4-way zoom function of the LG-G1 only can zoom the picture bigger and not smaller.)
The only bigger modification is the depth. i mounted a 5.4 cm thick wooden plate on the original bracket from the plasma screen of the BV9. the LG-G1 with its gapless wall bracket is then mounted directly on this plate. so the new screen ends exactly in depth with the BV9 frame.
switch on / off LG-G1: Unfortunately, no existing lg ir-puc of the beosystem 4 works for the LG-G1. that's why i'm doing a little work around. i use a macro in beoliving intelligence. if the beosystem 4 is online and the correct hdmi input is selected - the bli switches the LG-G1 on or off using the LG webOS TV driver. the whole thing also works with suitable timings when you switch to the cinema control. (With a little fine adjustment, the electronic curtains also work in this setup.)
1080p: here the LG-G1 works like a normal monitor. all devices and speakers are connected to beosystem 4 and everything works like in the original bv9. the LG-G1 then scales the 1080p image up to 4k. (it even works amazingly well!)
4K directly on the LG-G1: that is a little more complicated or more extensive. I decided not to use the LG-G1 internal apps. (Unfortunately, these cannot be controlled remotely with the beo4 via a puc.) So I decided on an additional apple tv-4k which is connected directly to the LG-G1. the sound is then transferred to the beosystem 4 via the e-arc output from the LG-G1 via an eARC audio extractor (including a black screen). there the audio hdmi cable is connected to a free hdmi port on the bs4 and set with the apple tv puc. the hdmi input switching from the LG-G1 is then again taken over by a macro on the beoliving intelligence. so everything can easily be remote-controlled via the beo4. (the overlay, the electronic curtains and the cinema control of the BS4 does not work in this setting!)
so, that was a quick summary - all in all, i'm very satisfied with the upgrade. compared to the old plama screen of the bv9, the LG-G1 has an unbelievably good and great picture.
attention: for the upgrade you need a basic technical understanding and the service manual of the bv9. you should also be able to program the beoliving intelligence. unfortunately only the LG-G1 evo 55 fits. the cheaper lg oled screens are a few mm wider and therefore not fit in the housing of the bv9. here are a few pictures of the upgrade.

Great job! Congratulations!
For the motor stand (BS3) you might be interested in this new product - the BM7 adapter - see:

And the BM7 adapter can also control the LG TV (not only on/off, but the whole TV.
Are you using the Atlona HD4 HDMI switch sold by Atlona or the B&O version?
And does the change beteween TV- and Cinema mode perform like it does with the BS3? (closing curtains on the BV and opening curtains on the cinema screen...including display on the cinema screen for volume setting, TV channel name..)

hi stefan! sounds promising. I'm curious when it will be available and more information will be available. (I only know the solution for the stand topic via lintronic)

I use the normal Atlona AT-HD4-V42 version. (According to b & o support there is no special firmware - at least that was the information I received) so I only made a firmware update from the atlona homepage. the Atlona AT-HD4-V42 is recognized by the beosystem 4 and a second output appears in the menu. there is also the timing menu in the service menu (as in beosystem 3)
yes, as I wrote, the 2nd screen setup works with the electronic curtain (on the lg and on the projector) including the overlays (volume, etc.) and cimena timing - but only if you use the beosystem 4 as a 1080p switch. exactly as described in the 2nd screen service manual. (in the 4K setting mentioned above, the 2nd screen setup does not work!)
Rudi should know more about the BM7 adapter - it seems that he is involved in this project.

Would you tell me what "fine adjustments" were necessary to get the electronic curtains work?
Thanks for all the information
stefan:Would you tell me what "fine adjustments" were necessary to get the electronic curtains work?
hi stefan
I meant the timing in the beoliving intelligence at the right time to switch the LG-G1 on or off. (so that the G1 starts before the electronic curtains are opened - but not too early so that there is no "no channel" overlay from the LG. Furthermore, the timings in the service menu of beosystem 4 and in beosystem 3 (for the stand) precisely adjusted (to control projector, screen, light, curtains, etc. in the 2nd. screen cinema setup)
The only disadvantage when using the LG-G1: when starting it briefly displays an overlay with "Hdmi1" this appears for a few seconds (before the electronic curtains open) and unfortunately cannot be deactivated in the LG menu.
