Adding An External Speed-Through-Water Sensor - Airmar PB200 Owner's Manual & Installation Instructions

The Importance of Understanding True Wind Direction
When the WeatherStation Instrument is stationary, the direction from which the
wind is blowing is known as the true wind. The WeatherStation Instrument is
programed to measure the direction based upon the specific orientation of the
sensor. For the WeatherStation Instrument to accurately calculate the true
direction of the wind, it must be installed and oriented correctly. (To learn more
about true and apparent wind direction, see Appendix A.)

Adding an External Speed-through-Water Sensor

The WeatherStation Instrument can receive data from an external sensor when it
is connected through an optional NMEA 0183 Combiner or connected to an
NMEA 2000 network. An external speed sensor processes additional received
data and transmits it to the WeatherStation Instrument for use in true wind
calculations. In the case of NMEA 0183 protocol, simply connect the sensor to an
NMEA 0183 Combiner or other NMEA 0183 repeater hardware. The data
provided can be seen on displays connected to the Combiner. An NMEA 2000
speed sensor can be connected to an NMEA 2000 network.
NOTE: When an external speed sensor is connected to both an NMEA 0183
device and an NMEA 2000 network, the WeatherStation Instrument will use
NMEA 2000 data.
Speed-through-water sensor—An external speed sensor can be installed, such
as an Airmar Smart™ Sensor. Airmar recommends installing the DST800V to
receive water depth, boat speed, and water temperature data.
