WindSonic node address
The default setting is ‘Q’. If required the WindSonic M can be configured to show a
different alphabetical node letter (A to Z), so as to identify the WindSonic M.
It is recommended that ID’s A to F and K, M, N and P are not used, as these characters can
be present in the data string.
Wind direction
Indicated in degrees, from 0 to 359
, with respect to the WindSonic North marker.
Whilst the wind speed is below 0.05 metres/sec (K50), then in Comma Separated Variable
mode no direction value will be output (e.g. Q,,000.03,M,00,1C). In Fixed Field mode wind
direction output will freeze at the last known valid direction value (e.g. Q,133,
000.02,M,00,1A) until a new valid value can be calculated.
Wind speed and units
Shows the Wind Speed in the Measurement Plane
(See Figure 3 Alignment & Mounting
details)
in one of the following units:
Units
Identifier
Metres per second (default)
M
Knots
N
Miles per hour
P
Kilometres per hour
K
Feet per minute
F
Low Wind Speeds (below 0.05ms)
Whilst the wind speed is below 0.05 metres/sec, the wind direction will not be calculated.
In CSV mode no direction value will be output (e.g. Q,,000.03,M,00,1C). In Fixed Field
mode wind direction output will freeze at the last known valid direction value (e.g. Q,133,
000.02,M,00,1A) until a new valid value can be calculated.
The above applies with the K command set for K50. If K for instance is set for 100 then the
above applies at 0.1m/s.
