?? Command Help list
6.4.1 SET01nn SET OUTPUT MODE
This enables and disables 0-5000 mV output, 4-20 mA current
output, RS-232, and RS-485. Only one of the two analog output
types (voltage or current) may be enabled at one time. Both RS-232
and RS-485 can be enabled at the same time but only one serial
output may be used.
Add together values shown in 6.4 COMMANDS SET01 to configure
multiple compatible modes. For example, to enable voltage output
and RS-232, add the code for each one: 01 + 04 = 05, SET0105 . To
enable only RS-232, SET0104 .
To conserve power, enable only those modes that are needed
6.4.2 SET02n OUTPUT FORMAT
This parameter determines the serial output format.
6.4.3 SET03nn BAUD RATE
Sets the baud rate for RS-232 and RS-485 serial communication.
Make sure this baud rate is the same as the connected device.
6.4.4 SET04n ASCII and NMEA WIND SPEED UNITS
Sets wind speed units for polar ASCII, ASCII POLLED, and NMEA
serial outputs.
6.4.5 SET05c POLL ADDRESS CHARACTER
Sets the sensor address for ASCII POLLED serial format. The default
is '0' (ASCII 48). This is the address recognized when the 'Ma!' polling
command is received ('a' is the address character). Valid address
characters include 0-9, A-Z, and a-z.
6.4.6 SET06nn WIND SPEED THRESHOLD
Sets the wind speed threshold for polar outputs (wind speed and
direction) to minimize erratic wind direction indications at very low
wind speeds. This allows the sensor output to mimic a mechanical
wind vane that retains its orientation when there is no wind.
Wind below the threshold is reported as zero, while the wind direction
angle is held at the last value when wind speed was above threshold.
Set threshold in centimeters per second (m/s x 100). The default
setting is 25 cm/s (0.25 m/s, 0.56 mph).
6.4.7 SET07nnnnn WIND SPEED MULTIPLIER
All wind speed measurements are multiplied by this parameter. The
default value is 10000 for a multiplier of 1.0000.
6.4.8 SET08nnnnn WIND DIRECTION OFFSET
Use this parameter to add or subtract a wind direction offset. Value
is degrees x 10 and may be positive or negative. Wind direction is
always re-scaled to a 0-360 range after offset is applied. The default
value is 00000.
6.4.9 SET09nn DAMPING FACTOR
Wind measurement outputs are damped using the following formula:
S
damped
= [(d-1) * S
damped
+ S
sample
] / d
where:
S
damped
= New or last damped wind speed
S
sample
= New wind speed speed
d = Damping factor
The default value is 00. This means no damping is applied. High
damping values at long output intervals can slow the rate at which
indicated wind values change.
6.4.10 SET10nnnn OUTPUT INTERVAL
Sets the time interval between measurements in one millisecond
increments. Lower values increase power consumption when
continuous measurements are taken.
6.4.11 SET11nn ANALOG DIRECTION SCALE
Sets wind direction analog output scale to 0-360 or 0-540 degrees.
Use the 0-540 scale whenever possible to avoid full-scale analog
output swings between 0 and 360 in variable north wind. (Data
loggers or display systems may otherwise obtain samples midpoint
during these transitions causing erroneous readings.)
Logged data in 0-540 form may be re-scaled to 0-360 by subtracting
360 degrees from any value greater than or equal to 360. The
default parameter setting is 0-360 for systems that cannot re-scale
the 0-540 output.
6.4.12 SET12nnn SAMPLE COUNT
The rate at which the sensor internally takes complete sonic wind
samples is greater than 200 times per second. This command
sets the number of internal samples used to calculate the median
measurement result.
More internal samples consume more power while providing greater
immunity to conditions like turbulent high-speed wind. Fewer
samples consume less power while providing less immunity to
disruptive conditions.
This command interacts with the OUTPUT INTERVAL setting. More
samples may require a longer output interval.
