Author Topic:   "Command" nomenclature

I have asked this question before. Is the use of the word "Command" part of a NMEA-2000 proprietary requirement, or just a co-incidence, or one-copying-the-other situation? I think it's unusual that both Yamaha and Evinrude would use this word for their own Smartcraft-type systems.

I believe SMARTCRAFT, as it has been described on this site, is more appropriately described as "NMEA-2000-like" than the NMEA-2000 instruments from Evinrude and Yamaha would be described (rather inappropriately) as "Smartcraft-like".

This based on the technical aspects outlined by JimH in another excellent article on the subject, detailing the fundamental differences in the systems' expandability and networking abilities.

It seems that the NMEA standard allows for a very complex network of sensors and displays, while the SMARTCRAFT, while certainly a very nice and effective system, has a rather limited expandability.

Not that this matters much to those of us with an average, or even a larger-than-average outboard powered craft. The complexities that NMEA enables can't be fully realized unless implemented on a much larger craft - like a 50' Hatteras (which, by the way, is a Brunswick brand). For us, either system would give great functionality and are very nice systems.

It is curious that both Yamaha and Bombardier ended up with the word "Command" in their gauge model names. Evinrude had been using the name "Commander" in their gauges previously. I don't know if Yamaha had previously employed the word "command" in their instrument accessories or not.

As far as I know, there is nothing in the NMEA-2000 protocol which specifies use of particular trade names. This similarity in naming between Yamaha and Evinrude is just a coincidence. Yamaha has been know to emulate other manufacturers in the past.

Also, it is confusing to refer to a " NMEA-2000 proprietary requirement."

NMEA-2000 is not a proprietary system. It is an open standard which the marine electronics manufacturers have agreed to and published. Anyone can obtain a copy of the standard (although you can't get it for free, you have to buy it--and it is too damn expensive if you ask me--probably on purpose to keep experimenters out of the system). The information is openly divulged to interested parties.

Proprietary means private or protected, a secret. No one can obtain information about a proprietary electronic device unless the owner of that information wishes to divulge it. Generally, owners of proprietary information do not wish to divulge it.

Jim - What I had meant is that NMEA might own or trademarked the word "Command" and require that any Outboard manufacturer who uses this standard incorporate the word Command name?

What term is Honda and Suzuki using for their instrumentation using NMEA 2000 standard? Does anybody know? Maybe one them will use "SmartCommand"!
