TSN Evaluation kit


I am currently studying TSN application and find EVAL-RapID-TSNEK kits in ADI. Documents show these Kits can be a TSN gateway for connecting non-TSN devices.

If I would like to set up a Ring Topologies Network, would 3pcs of eval kits be enough for the testing?

Besides, might I know where I can find software / firmware codes and datasheet in Fido5000? Any NDA require for accessing these information?

Thank you.
