RealPresence Touch monitors

Hi,

I found, that Group 310 needs additional licence for touch monitors integration (Group Series 300 or 310 Enhanced Display Software License. Enables two features.  1.) Enables 2nd monitor output (HDMI) on codec. 2.) Interop with supported touch monitors in either single or dual configurations.  Valid for Group 300 or 310 only).

Does Group 500 also need some licences or this feature is enabled by default?

Does anyone have some good/bad practice using touch monitors?

Thanks.
