Configurable Parameters
Table 53 below lists the configurable parameters and their
allowed and default values for the SDI-12 profile.
Table 53 Configurable Parameters for SDI-12 Profile
Parameter Default
Value Profile-Specific
Allowed Values Description
address 1 1, 2, 3, 4, 5, 6, 7, 8, 9 Address for WMT700
autoPort 1 1 = COM1 port
2 = COM2 port Serial port to which WMT700 sends automatic
data messages
autoSend 0 0 = Automatic messages
disabled Automatic data message number. Selects the
data message format for automatic messages
com1_protocol 0* 1 = SDI-12 Profile for serial port COM1
com2_baud 1 1 = 1200 Baud rate for serial port COM2.
Changes take effect only after reset or the
RESET command.
Note that low bit rate can affect measurement
timing, if WMT700 cannot send the data message
before new measurement starts
com2_data 7 7 = 7 data bits Data bits for serial port COM2.
Changes take effect only after reset or the
RESET command
com2_interf 0** 2 = SDI-12 Interface for serial port COM2
com2_parity 1 1 = Even Parity for serial port COM2.
Changes take effect only after reset or the
RESET command
com2_protocol 1 1 = SDI-12 Profile for serial port COM2
com2_stop 1 1 = 1 bit Stop bits for serial port COM2.
Changes take effect only after reset or the
RESET command
wndAvg 1 0.25 … 3600
Resolution: 0.25 Averaging time for wind measurement in seconds
wndOrientation 0 0 = Array facing up
1 = Array facing down Orientation of the array of WMT700
wndUnit 0** 0 = Meters per second
1 = Miles per hour
2 = Kilometers per hour
3 = Knots Wind speed unit
wndVector 0 0 = Scalar averaging Wind averaging method
* The parameter has no protocol-specific default value. It is determined
separately in the configuration code.
** Wind speed unit and COM2 digital communication interface are defined in
the order form. Default setting may be any of the allowed options, and it can be
verified from the unit’s configuration code.
To start continuous measurement, use the START command.
You can stop the measurement with the STOP command. For
instructions, refer to sections START — Start Continuous
Measurement and STOP — Stop Wind Measurement on page
115.
