WMS-16 Weather Station Operator’s Manual 7
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
Handshaking Xon/Xoff
