[TG11]EVO-1 Yaw,Pitch,Roll PGN Ranges

I have recently setup a NEMA2000 gateway so I can capture data from our EVO-1 autopilot. The autopilot is outputting nagivation.attitude PGN (127257) for yaw, pitch, and roll. The values seeing in basic testing at the dock in some light chop are showing under a 1.0 value for all three attributes.

My question what is the data range for this PGN as I would like to translate this to degrees. Because actual range can be measured in 360 degrees I would need to understand the max/min for the PGN and the neutral reference point.

The example would be for say roll. If the boat rolls 10 degrees port than to 0 degrees roll than 10 degrees to starboard what would those values look like.

Cheers and thanks for making the data available out of the EVO-1

Hello scurvydog,

Since this isn't a Raymarine-specific thing but a message that's defined within the copyrighted NMEA2000 specification I am sorry to say that we can't help you reverse-engineer that standard, but as a hint - other people have already done this. The answer to your question is online if you look for it.

Please don't PM me asking for direct support, please ask a public question instead so that others can see the question and answer. Forum posts will always be answered before PM requests.
