WA — Fetch Averaged Wind Speed and
Direction
This command requests the averaged wind speed and direction
message with peak winds.
WA <CR><LF>
The response to the WA command consists of the averaged wind
speed and direction data, peak wind speed, and associated
direction. The average wind speed is a scalar running average of
the fundamental
1-second interval wind speed measurement made by WMT700.
For a description of the data message, see section WS425 F/G
ASOS Data Message on page 152.
You can set the wind averaging time and gust time with the
wndAvg and wndGustTime parameters. Set the wndVector
parameter to 0 to use scalar averaging.
The command also fetches the WMT700 status, the averaging
time for average and peak wind speed and wind direction, and
signal quality.
WS — Fetch Internal Diagnostics Information
This command requests the verbose Built-In Test (BIT) results.
WS<CR><LF>
The command gives a textual run down of the results of all Built-
In Tests (BITs). In every line, except the bad reading counter, the
pass/fail indication is given with the single character P or F. This
is followed by the description of the measured parameter, which
is followed by the actual measured value.
The Bad 1 second readings counter is a running total of the
number of fundamental 1-second readings that the sensor flagged
as bad. This number rolls over to zero after reaching the count
value of 65535. It is initialized to zero on each power-up or any
other activity that performs a re-initialization of the sensor. The
time measurement quality indices are given for path numbers as
follows:
- Path 0 is from south transducer to north transducer
- Path 1 is from north transducer to south transducer
- Path 2 is from north transducer to east transducer
- Path 3 is from east transducer to north transducer
- Path 4 is from east transducer to south transducer
- Path 5 is from south transducer to east transducer
