RAA100 NMEA 2000® Periodic Data Transmitted PGNs
PGN 127245 – Rudder
The RAA100 uses this PGN to indicate the attached rudder instance and rudder angle.
Field 1: Rudder Instance – This field is used to identify the rudder instance number and ranges between 0 and 251.
2:Direction Order – This field identifies a directional command contained in this message. The RAA100 ships from the factory with a default value of 0x0 indicating that no direction order is contained in this message.
3:Reserved – This field is reserved by NMEA; therefore, the RAA100 sets all bits to a logic 1.
4:Angle Order – This field is used to indicate an angle order directed towards a rudder actuator The RAA100 ships from the factory with a default value of 0x7FFF indicating that no angle order is present in this message.
5:Position – This field is used to indicate the current angle of the rudder in units of 0.0001 radians.
6:Reserved – This field is reserved by NMEA; therefore, the RAA100 sets all bits to a logic 1.
