I guess it can be called open, because the spec is actually available
for anyone to use and implement, albeit for a hefty sum of money. 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).
