2.
To set the Triggering for
Digital Output
or
Analog Output
, follow the steps below:
Click in the Enabled
box to turn on Trigger digital/analog output.
For the Logic level, click the arrow to select a level (for digital output only).
For the parameter, select one of the sensors (
Note
: For air velocity, verify the sensor is
attached to the EVM and selected in the
General
panel of DMS.)
For the threshold, type in a value for the selected parameter or use the
to select.

To set the triggering setup, click on
or save and send to the EVM (for more details see
Saving and sending configurations
”).

Triggering
parameters
Explanation
Digital Output
Enables the digital output on the device when checked per the mode, parameter, and
threshold settings.
NOTE
: Only one of these parameters (Digital Output, Analog
Output, or Air Velocity) can be enabled at one time.
Analog Output
Enables the analog output on the device when checked. The analog output will vary
between 0-5 volts based upon the minimum and maximum levels for the particular
sensor.
Logic level (Also
called “Mode” on
the EVM)
The type of signal that will be triggered when the parameter and threshold are
satisfied. It may either be active high, active low, active high pulse, or active low pulse.
(Reference Table 3-3 for detailed information.)
Parameters
The sensor that is to trigger the digital/analog output.
Threshold
The threshold at which the sensor will be triggered for the given parameter.
Air velocity input
Enables the Air Velocity Input when checked.
NOTE
: This is mutually exclusive with
the digital out meaning that only one or the other can be enabled at any given time.
Units
Sets the units in which the wind speed will be measured, either meters per second or
feet per minute.
