Page 8: Nmea 2000® Interface
NMEA 2000® Interface The Airmar PB200 WeatherStation has a single NMEA 2000®-compliant network interface, and is expected to be certified as a Class 1 Level B device. The PB200 transmits and receives standard and proprietary NMEA 2000® Parameter Groups via this interface.
Page 9: Sequence Id (Sid)
In this case, the address of the destination device must be provided within the PGN. Query Support: If the parameter group supports queries, then the PB200 will transmit the parameter group if requested by another device on the bus. The request must be made using either the ISO Request PGN 59904, or the Complex Request Group PGN 126208.

Page 16: Pgn 065287 Proprietary: Access Level
Notes The Access Level proprietary PGN is a security mechanism that provides the PB200 with a method to limit access to certain functions to devices that understand the proper unlock sequence. Certain operations will not be possible unless the Access Level is first increased to the required value. A nonzero Access Level remains in effect until the unit powers down, or 15 minutes has elapsed, whichever comes first, after which the Access Level returns to zero.
Page 17 This PGN does not respond to ISO Requests (PGN 59904). When this PGN is transmitted, field 5 contains the current Access Level of the PB200, and field 7 contains a randomly-generated Seed that may be used in a subsequent Unlock operation.
Page 18 Access Level was in fact changed. Note that increasing the Access Level does not in and of itself allow global access to the secure functions of the PB200. The Access Level is changed only for subsequent commands and requests originating from the device with the source address originally used to specify the Access Level.

The programmed values are stored in nonvolatile EEPROM memory within the WeatherStation, and so remain programmed even after cycling power. The azimuth offset angle is used by the PB200 to adjust the apparent wind angle relative to the bow of the vessel, and the vessel’s heading measured by the internal compass.
Page 25 PB200 WeatherStation User Manual revision 1.000 Proprietary and Confidential The azimuth offset angle, along with the pitch and roll offset angles, are also used to adjust the reported pitch and roll values in the transmitted PGN 127257, and in the transmitted NMEA 0183 $WIXDR sentence.

Page 28 Calibration needs to be done in calm seas, away from other boats or ferrous objects (structures or aids to navigation). Trying to turn a 2-3 minute circle in strong currents or congested areas will be difficult, if not hazardous. The user calibration sequence for the PB200 is as follows: The weather station instrument is installed on the vessel. The unit under test is powered up.
Page 29 PB200 WeatherStation User Manual revision 1.000 Proprietary and Confidential Note: During user compass calibration, heading is not valid and will be output as DataNotAvailable. Also, air temperature is set to 0 degrees Celsius. After calibration is complete, heading will again be valid, and if successful, air temperature will also return to the current temperature, but if calibration fails, air temperature will be output as -10.0 degrees Celsius for 30 seconds.

The various types of data provided by the PB200 are sampled, or measured, at different rates, depending on the nature of the data being measured. For example, the GPS receiver in the PB200 provides new position fix data once per second, while the wind sensor provides new data twice per second. The rate at which a given source of data is measured is unrelated to the rate at which its corresponding PGN is transmitted.

Some of the data in this parameter group will only be available once the GPS has achieved a position fix. Other data will be available once satellites are being tracked. Fields 16, 17, 18 are repeated for each station indicated by field 15, and therefore are not present when field 15 is 0, which is the case for the PB200.
