Actually, there were 11 vendors showing off products at IBEX that were CAN
based and used the NMEA 2000(R) messaging protocols. 7 of those 11 have
already certified their products to NMEA 2000(R), but the others probably
won't be far behind.
At the Miami Boat show, look for the NMEA 2000(R) ConnectFest where
manufacturers of certified NMEA 2000(R) products are expected to demonstrate
multiple vendors products exchanging data on one network.
