Default When is a different start code allowed?

Hello all
I have 2 products here that state that they both comply with RDM but when I try to detect the responder with my controller, nothing happens.

In fact, my sniffer does not even detect any RDM packets if these 2 units communicate.
I then looked at the data manually and found a start code that is not 0xCC.

Could someone please clarify when it is allowed to state RDM on a product but use a non RDM start code for all packets?

If this is permissable, then who assigns these other start codes and under what conditions?

Kind Regards
