I was looking through the Airmar website and found an interesting device. Their U200 is a NMEA 2000 to USB portal. They market the product as a way to monitor Airmar sensors on a NMEA 2000 network. Not very practical for a small open boat, but maybe useful for a large sportsfisherman or cruiser. However, I am curious--do you think that ETEC EMM data could be accessed through this connection? The data sheets are on pages 33 and 34 of the Airmar catalog at this address:
<http://www.airmartechnology.com/uploads/brochures/AIRMAR%20Transducer%20Guide%202009.pdf>. I am curious to see what the more tech savy among us will think.

I found information on page 34--a list of NMEA-2000 PGN's that can be translated. In order to get engine data from an E-TEC EMM, the U200 would have to translate the engine data PGN's. Most of the engine data is sent in:

--PGN 127488: Engine Parameters, Rapid Update, and

--PGN 127489: Engine Parameters, Dynamic

Cf.: http://continuouswave.com/whaler/reference/PGN.html

Compare the list of PGN's translated to the above list, and see if the device translates the engine parameter PGN's. At my first glance, I don't see those PGN's listed on the U200 document. On that basis, I don't think you will find the U200 to be useful as a way of getting engine data from an E-TEC EMM onto a USB connection using the AIRMAR U200. However, if you are interested in that device, I recommend you contact AIRMAR technical support and get their opinion.

Also, the document from AIRMAR you are referencing is from 2009. I suspect that the capabilities of the U200 may have been enhanced since then. This is another good reason to check with AIRMAR technical support to get the answer you are seeking.

Another gateway device that transports NMEA-2000 to USB is the Actisense NGT-1. See
