B&O Beomaster 5500 with MCP + Beogram 5005 and CD-50

Hi forum.

I've been using my Beomaster 5500 now for several months now and yesterday i bought a used but in really good condition CD-50 and Beogram 5005 - now the question is, that can my Master Control Panel 5500 control these devices without problem, since they are from different series than my receiver? Right now the panel only controls the Beomaster. searched little bit and found that 7DIN plug might be the answer but before i buy anything else, i"d like an opinion.

Thanks

Yes, they all use datalink to communicate. As you mention, you need the 7 pin connection to establish communication between the sources and the receiver.
