Does assigning the diagnostic bus to a specific bus do anything in a single master system? I've connected to systems with IQANrun and IQANgo on busses that are not designated diagnostic without any issue. As far as I could tell, they had full functionality within the apps. It seems more like whichever bus you connect to using IQANgo or IQANrun has full diagnostic ability, as long as it is not of a type that can't mix with a diagnostic bus.
