Introduction
This document is a supplement to the Airmar PB200 WeatherStation Owner's Guide.
The PB200 WeatherStation is a multifunctional device that integrates several sensors into
a single compact housing. These sensors include:
•
Ultrasonic anemometer, providing apparent wind speed and direction
•
Thermistor, providing air temperature
•
Piezoresistive pressure sensor, providing barometric pressure
•
Magnetoinductive XYZ sensors, providing tilt-compensated magnetic compass
heading
•
3-axis MEMS
1
accelerometer, providing pitch and roll angles
•
MEMS rate gyro, providing rate-of-turn of the vessel
•
Global Positioning System (GPS) receiver, providing position, and speed and
course over ground
In addition to the above directly measured parameters, the PB200 WeatherStation is able
to calculate the following values as well, if the necessary data are available:
•
True wind speed and direction
•
Heading relative to true north
•
Apparent wind chill temperature
•
True wind chill temperature
•
True wind speed relative to water (with optional Airmar® Smart™ speed sensor,
not included)
The PB200 WeatherStation has two separate communication interfaces: one compliant
with the NMEA 2000®
2
protocol, and the other with the NMEA 0183 protocol. Both
interfaces are able to operate simultaneously and independently from one another.
This document provides detailed descriptions of the communications protocols for the
NMEA 2000® and NMEA 0183 interfaces used by the PB200 WeatherStation.
For further information about the NMEA 2000® protocol, refer to the document, NMEA
2000® Standard for Serial-Data Networking of Marine Electronic Devices, version
1.200. For further information about the NMEA 0183 protocol, refer to the document,
NMEA 0183 Standard for Interfacing Marine Electronic Devices, v3.01. Both of these
documents are available from the National Marine Electronics Association
(
