WMS-16 Weather Station Operator’s Manual

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

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

Station Setup

Press “Esc” to get to the main menu. Press “1” at the main
menu to initiate the Station Setup procedure. This procedure
allows you to specify certain operational parameters that the
WMS-16 uses in its calculations and on its display. Run
Station Setup when using the weather station for the first time.
After that, ignore it – unless you wish to change one or more
of the settings.

When you press “1” at the main menu, the parameters
available for customizing appear as items 1 through 8. 

Station Name

1.

 

Type the name of the station. 

2.

 

The station name may be any series of alphanumeric
characters up to 50 characters long. After the station
name is entered press “Enter” and select the next
item.

Units of Measure

Press 2, Units of measure. A warning message will appear
stating, “ Changing units will cause data to be logged in the
new units of measure”. You should clear logging memory to
avoid mixed data values. Do you want to continue? [Y or N]:
If you want to change units of measure press ”Y” and the
menu will ask you English or Metric? Select E or M and press
“Enter”.

The menu will ask if you are sure you want to delete log file
[Y or N] if you have changed units then answer “Y” if not
“N”. and press “ Enter”.

Averaging Period

Press 3, Averaging period. The averaging period is user
selectable over the range from 1 minute to 60 minutes.  The
stored data will be the average of the data measured at five-
second intervals over the user selected averaging period. If the
