Networking of Marine Electronic Devices available from NMEA.
Notes
Different instances of this parameter group may be simultaneously enabled to transmit with different selections for the Wind Reference field. This may be done using the Request
Group Function PGN 126208, specifying the Wind Reference field as one of the requested parameters. If the Wind Reference field is not specified in the Request Group Function
PGN 126208, the default wind reference (0x02, Apparent) is assumed. In addition, the update rate (transmission interval) may be individually specified for the different wind
references using the Request Group Function PGN 126208.
The Priority field of this parameter group may also be individually specified by Wind Reference using PGN 126208, Command Group Function.
Wind data using reference values 0x00, 0x01, and 0x03 will only be available once a GPS fix has been achieved. Wind data using reference value 0x04 will only be available if
Speed Water Referenced is available on the NMEA 2000® bus from a device transmitting PGN 128259, or from a water speed sensor providing the VHW sentence on the PB200
NMEA 0183 input.
By default, two different instances of this parameter group are transmitted: the first with field 4, Wind Reference, set to 0x02 (Apparent), and the second with field 4 set to 0x00
(True referenced to North).
