Could somebody please explain the "Open" in NMEA-2000??

Open is not the same as free. And I guess there are no per unit licensing fees that have to be paid if one implements NMEA2000 in one's product. Is this really true? I noted a reference to NEMA 2000 certification in the link posted by the OP. What are the terms of this certification? Can I purchase the spec, implement a product and get it certified if my product happens to be a reference implementation of the entire spec, complete with commented source code to be distributed with the product? Maybe something like a NEMA 2000 development kit (just a CAN development board with a documented NEMS 2000 protocol stack included). -- Paul Hovnanian ------------------------------------------------------------------ Q: Why do mountain climbers rope themselves together?
