S I N G T H E Everything you need to know about running the software (once it is correctly installed) is explained in this chapter. E A T H E R T A T I O N Depending on which optional sensors you have connected to your station, certain information and options within the software may not function or display data.
S I N G T H E O F T W A R E File Menu I L E The file menu contains commands relating to station files and sta- tions. Each command is explained separately below. New Station Each station connected to the computer must have its own “station” within the software.
Open Station Only one station may be open at a time. That way the software knows into which database downloaded data should be saved, which communications settings to use, which database to use when plotting, etc. 1. Choose Open Station from the File menu. The Open Station dialog box appears.
S I N G T H E O F T W A R E File Menu View Log Information about the automatic download of your station(s) is automatically written to a file called “download.log” which is saved onto the hard disk in the directory “ahead”...
To compare databases archived on separate computers, copy the station configu- ration file, as well as the source files, from the source database. See “Database Organization” on page 97 for details on the station configura- tion and source files. The data merge does not change the time or data of merged data. This means that it can not solve the problem of weather stations that have been re-powered and thereby had their dates reset to January 1.
S I N G T H E O F T W A R E Setup Menu The commands in the Setup menu relate to station and soft- ware setup. Each of the commands is explained separately below. Walkthrough The station setup walkthrough automatically steps you through the entire station configuration procedure.

E C H N I C A L R E F E R E N C E This chapter covers several technical topics which may help you better under- stand and use the software. R C H I V E E M O R Y V S There are two places where the WeatherLink stores weather data: the archive memory and the database.
E C H N I C A L R E F E R E N C E Automatic Download The weather station actually reads atmospheric pressure not barometric pressure. When you set the barometric pressure from the station, the station automatically calculates the difference between the barometric pressure you enter and the atmo- spheric pressure it reads.
A T A B A S E R G A N I Z A T I O N Station Directory When you create a new station the software creates a station directory (using the first eight characters of the station name, not including any spaces and punctua- tion) in the root program directory.
E C H N I C A L R E F E R E N C E Modem String Database Files The software stores downloaded data in monthly files. Whenever you download, the software saves database files into the open station's directory. The file name which the software applies to database files indicates the year and month of the data.
The software can perform some troubleshooting of modem problems in the form of error messages. In order for the software to provide error messages, any modem initialization string you enter must contain the E, Q, and V strings. Note: If you use another communications program after using the modem with the WeatherLink Software, you may need to re-initialize the modem using the modem string expected by the other program.
