Additional Data Available from the WeatherStation Instrument

There are parameters that the WeatherStation instrument can make available to

the user. Usually, more data is available from the WeatherStation instrument than

can be displayed in a reasonable format on a screen. Also, if all the data was

continuously transmitted to the display, the update rate would be too slow and

could not keep up with WeatherStation measurements. Consequently, some

parameters are transmitted while others are not, based on a pre-selected list (the

NMEA 0183 sentences with an asterisk). Note that those parameters not

transmitted are, nevertheless, retained in the WeatherStation instrument. For

more detailed information, see the “Technical Manual” on the WeatherStation CD.
