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.
