Now going through the list many small things are showing up that gives food to thoughts.

For example what is a Beolink Active type 1681, or a Beolink Converter to AV7000 BEO4 type 1612 (very specific product name by the way)?

Probably small differences from the normal product line that served a purpose on a specific market, but very interesting to dive into.

This one perhaps, at least it does has some BL Actives and passives? (Found it after first finding this which had a link).

Yes that was the one I was thinking of. Thank you very much 😀 Look like it was on the archived forum, but in the form of a WIKI page instead of a forum post.

Sadly no mention of Beomaster ROMs, I guess the list dates from 00’s or later (the comment says 2013) as the oldest products I could see were Beolab Penta, Beovision MXs and even a “8341140 MASTER CONTROL LINK 2AV 2020 2.3” still hanging in there.

Yes not going back as far as I thought, but it may be a usefull foundation for an updated version.

@Multicare is it possible that this WIKI list can somehow be integrated in the current Beoworld technical section so it’s easier to find for future reference?

In the best of all worlds it could be great with a list with all software revisions for each product with revision notes like those for the BM4500 update in this thread https://forum.beoworld.org/forums/topic/beomaster-4500-two-way-roms/

However unless official documents that explains the software update revisions can be found it can be hard to be sure what a software update does. I tried to make a revision list for the Beolab 3500 software versions in this post https://forum.beoworld.org/forums/topic/bl3500-and-the-mcl-pl-connector/page/3/#post-44591 based on forum post’s stating what an update did. However some of the information seems to be conflicting with each other and with what I have tested so hard to make such a revision list without official documentation to back it up.

Also there might be an issue documenting all subrevisions like the example in this thread https://forum.beoworld.org/forums/topic/beolink-active-sw-1-64/ where the sticker on the outside of the Beolink Active says 1.6, but the one on the chip says 1.64.

Not that one either, although a great reference for certain products.

no it was more of s comprehrnsive list with profuct names, type numbers, latest SW version, and it was everything from TV’s, music systems and Beolink converters, Beolinl Actives and Passives etc.

No it was the older era of products from the 80’s, 90’s and early 2000’s

I tried to look at Beoworld via Archive.org and can see that it was not a Part of the Beotech section, but remember it as being a subpage of some kind on Beoworld. Not a forum post

Then I used the Beo4 to press SHIFT 9 0 2 5 8 and was surprised when this opened the Service Menu – very strange because this is not how the Service Manual says that the Service Menu is entered.  (The manual says MENU GO, then 0 0 GO.)

(The SHIFT 9 0 2 5 8 sequence is actually the button sequence for Service Mode on a BeoSound 1, and possibly other systems).

Great work thinking out of the box, but very weird that this works. Maybe different software version did change something, but nok very smart in regards to servicing.

On thing that came to mind in this regard is, could it have been updated with a wrong software? Do you have a history of it being used before not working anymore?

NVEM: TP_MODULE_HW_ERROR_APOS (keeps re-appearing, even if I manually clear error)

VMEM:  As above plus MLSL_STATUS_ERROR (VMEM errors are cleared by unplugging)

I also looked in the BS4 servicemanual but could not find anything either. Then I tried a google search, and some references to the Beocenter 2 servicemanual came up.

Looking at that the MLSL_STATUS_ERROR seems to be ML related, but have different error types, so you might want to look that up to see if you can spot anything usefull.

Also a thread here with a BC2 with a similar error message, but no solution https://archivedforum2.beoworld.org/forums/t/36631.aspx

Being in the ML mindset I would suggest taking a good look at the ML connector to see if any legs are bent and touching each other. If not a survey of the ribbon cables between the socket board and the main board could be worth doing.

I’m pretty sure I’d have seen the black two-way terminal -stickers on somewhere else but can’t remember. Then again, I might be mistaking it for the similarily styled black BEOLINK sticker that can be seen on fe. BC9000’s back (no two-way IR there but I presume it hints to the device communications over the 7-pin DIN connectors and/or the MCL2 system).

Yeah it might be a one off on the 4500 since it was upgrade to the functionality. I just checked on my Beossytem 2500 that should be 2 Way (I have not have it functioning yet), and that does not have the sticker. Also I have 2 Beolink 7000 remotes where none of them have the sticker, and all the MCL2A and MCL2AV components does not either regardless of their 2 way comptability.

Very nice touch with the labels.

Do you know if these labels only was used for the 4500 since it got new functionality or if they were also used on other two way capable systems?

The chip in my unit (and the replacement) was a generic 27512 EPROM, which is still readily available. Mine was M27512FI, ie. by STMicroelectronics but any manufactorer should be fine (as long it’s the same 28-pin DIP package). I couldn’t find the speed rating for either chips, but in this case I’d guess the “slowest” 200ns part should work (elsewhere, like vintage computers the speed of the ROM might be important). You’ll also need an UV-eraser (for the old EPROMs with window on top) and an EPROM programmer. I’m sure there are also newer pin-compatible variants (EEPROMs, ie. no UV-erasing needed, or write-once chips if you just want to write a chip once and not re-use it).

Thanks for the info. I have the EPROM programmer, but might have to get the UV eraser.

I find it interesting that the BM4500 was shipped with the “limiting” software (if the 2-way IR hardware was fitted). Also the release notes telling a fix for “Beosystem 4500 may intermittently block and it is necessary to remove the mains plug” sounds pretty annoying bug, and surely would’ve caused calls to dealers! (I might have actually experienced this on my unit with the old ROM once or twice, I always thought it was just an effect of a low battery but apparently not!)

Yes something about the software for this systems is like B&O was not sure what to do with it. The link room functionality is only described as being in slave mode and for future use in the user manual, so not very official. I wonder why they didn’t mentione it instead of saying for future use

I first saw now that this was also posted here. Very great that you have made the software available :-). These softwares can be hard to track down if needed for a repair or an upgrade.

I might have a go at updating my BM4500 to 2way at one point in the future.

Would you happen to know if the eproms has to be the excact model or if other can be used?

Ah thank you – I didn’t know that ML to ML on a Beolink Wireless 1 was on later software only.  Mine are both earlier serial numbers than the one you have given, so I’m sure that’s it.

yes very likely then.

CharlieWednesday wrote:

It was only really for testing the capability of them anyway.  I’ll use them with PL speakers connected instead.

One thing to know is that there can be stability issues as they work on the 2.4Ghz waveband which is also used for WI-FI, Bluetooth, microwave owens, door bells, baby alarms, and probably a lot of other things. So inteference from one or more of the mentioned can happen. Again the servicetool is needed for changing the channel trying to avoid inteference, so not very user friendly on that account.

you might havea aolder software version on your BLW1 units

ML to ML on the BLW1 is supported from SW 2.1

This software version was introduced from serial number higher than 19956171. So if your units has a lower serial than that chances are you are on a lower software version.

As far as I know the only other way to check and update the software is with a dealer service tool.

And if you go for a higher software all wireless units has to be on the same version.

Hope this is helpfull

Another question do the Penta displays work when plugged into a BC9300. I have fully wired leads and they do work on the TV but not with my 9300. Is that a fault?

Not sure, but is it correct that there is a switch for selecting either Audio or Video on the socket panel of the Pentas?

If so maybe that will change the behaviour

Location: Denmark

[Madskp]

It sounds to me like both the TV and the BS9000 are set to option 2 (receiving both audio and video commands). If you change both to option 1 the V1 will only react to video commands and the BS9000 only to audio commands.

I think that would be the simplest in this setup

I dont know how to do the option settings with a BEO5, but if you have a BEO4 or s Beolink 1000 I can post the instructions

A little update to this thread as I have acqured an Almando Masterplay. More info about that in one of the first posts where this is mentioned as a solution for driving a BL3500 https://forum.beoworld.org/forums/topic/bl3500-and-the-mcl-pl-connector/#post-44537

But, when trying to play TuneIn (Radio) or Music (N.MUSIC) from the Moment then the BL3500 quickly indicate source and then powers off (including that it also powered off the BS6500 stereo) all other units in the ML-network.

I have not tried getting sources across 2 BLC’s myself as I only have one, but if thinking in ML termonlogy it sounds logical that if you switch to another source then you turn of the currently playing source, although that should not happen if the source is in use in another room. Does this happen both when the BS6500 has been started from another room and if has been started from the BL 3500, or only in one of the cases?

To be mentioned is that the Beolink 1611 has fw 1.3 and whether that is an issue or not…

I have yet to see or hear about another software version of the 1611 converter, so I would not think that as the issue.

You might want to set theBLC as A.master, V.Master or AV.master

On the tab: “sources visible to ML” you will have to define what ML source names your BV10and Moment sources should have when controlled from the BL3500

I wasn’t aware of that, so perhaps it’s a new product.  I assume it swaps the datalink across from pin 6 to 7.

I belive so.

I was aware of this older version, but I don’t think it’s available any longer:  http://www.iconic-av.co.uk/item/1321/RIAA+Pre-Amplifier+with+Datalink+for+BeoGrams/

Oneremote also had an other one before which I belive did the same. I found a picture of it here https://images.guloggratis.dk/listings/1280×1280/7002ab6a-e44c-455e-846e-f066e255c35b.webp

I have managed to find a used one of the brand Flint with the same feature, but I do not think that is available as new anymore.

Steve tells me he can make a datalink Din Bypass cable so hopefully this will solve the issue and I will have remote operation. Just waiting for him to get back to me and I’ll be placing the order.

Great to hear that is also an option. I wonder how that cable will look like.

An easy solution instead of making special cables could be the RIAA from Oneremote which also passes the datalink control signals
