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?

I haven't read the actual spec, since it costs money, but I was under the impression that there are no extra licensing fees. If you want to be sure, you'd better ask the NMEA folks themselves. Getting one's product officially certified probably incurs some costs anyway. Tapio |
