I have a BV 4-50 D10 panel working with a BeoSystem 3 MK II. I plan to exchange the BSys 3 with a BSys 4. I found two older threads mentioning that there are cables available for the connection of the BSys 4 to the BV panel. Or they may be made by one self, which is beyond my capability. It had not been specified which cables, which manufacturers those cables provide and where to get them. So I kindly ask for your support in answering the following questions: - Which cables do I need to connect the monitor control and the IR from the BSys 4 to the panel (article or order numbers would be nice 🤗) and where can I get them? - Is it possible to connect my DVD 2 to the BSys 4 and how? If someone is using this set-up or a similar one and has made the same endeavour happen, it would be nice and helpful to receive the experience made. Kind regards, Rolf P. S.: In parallel, I contacted B&O customer support and I am waiting for them getting back to me. I will of course share what information they provide.

Ah, I guess I should have placed this topic under „BeoSystem“. @Multicare: Please, move it there, if this would be the right place, thank you.

Other old thread suggest that you can also use HDMI to connect the DVD2 to a TV, but you will still need the start connection in order to get control. Not sure how this is setup on the Bsys 4 connection menu.

The biggest problem there will be to find this adapter (9 pin <-> scart female). I guess you could use an digital/coax connection for ‘better’ sound. The setup will be similar to setting up other external sources. As for using the HDMI….that will need some testing. MM

In the Beolink Handbook ver. 2.1 (available in the Beotech section) the whirring for the IR eye for both Bsys 3 and 4 is shown for IR eye's bot with and without auto contrast. From what I can you should be able to replace the existing cable in the IR eye with a standard network cable instead following the whirring diagrams in the Beolink handbook. Also in the Beolink handbook is the part numbers for the two types of 9 pin mini DIN to start cable. There is both one with a Female and a male scart. part numbers in the screenshot below:

Thanks a lot for the link to the respective thread. I will check with my dealer, if this cable will be still available. If not, maybe Steve can help. From my experience, the DVD 2 needs both connections, HDMI and Scart. The BSys 3 seems to connect them together automatically, if you choose the right connection plugs (in my case HDMI-In 3 and Scart 3). I do not know, if the BSys 4 does put the mini-AV and HDMI „XY“ automatically together, very likely not.

@Millemis: The cable from B&O can be found on the internet, e. g. a swedish seller. I would prefer to by at my dealer, which I will check, or maybe Steve can lend a hand. As mentioned before, the DVD 2 will need both connections, HDMI and Scart.

@Madskap: Thanks again for hinting me to the Beolink handbook. Did not think about that. The panel has a built in IR receiver, so I prefer to establish a direct connection between the BSys and the panel for IR control. There is also a specific cable for connecting the BSys 3 (Monitor control) and the panel. In this case I would need a rj-45 to DSUB9 cable for connecting to the BSys 4. I can find one from Panasonic on the internet, but it seems to be available on the Japanese market only, and I do not know, if it will be the right one.
