Once the main menu is present proceed with the station setup procedures as described in the next section.

OPERATION

The WMS-16 Weather Station collects and logs data automatically, requiring little user input. Ultimate control, however, is provided by the interactive user interface, which allows the user to direct the WMS-16 to perform certain specific functions by choosing one of the six options offered on the main menu

(Figure 3).

Software

The firmware contained in the WMS-16 has all of the programs required to use the weather station with a P.C. operating in the communications mode (such as HyperTerminal in Windows). Communication between the WMS-16 and the P.C. is made by connecting the RS-232 cable to either COMPORT 1 or COMPORT 2. In order to facilitate getting started if you are using Windows you may open the HyperTerminal program with all of the proper communication settings for communicating with the WMS-16.

The communications parameters required to interface the WMS-16 to an RS-232 data link are as follows:

Baud rate	9600
Data Bits	8
Stop Bits	1
Parity	None
