CSAT3Cmd Commands 90 - 92 send a measurement trigger to the CSAT3 with the SDM
address specified by the SDMAddress argument. The CSAT3 also sends
data to the datalogger. Options 97 - 99 get data after a group trigger,
SDMTrigger(), from the CSAT3 specified by the SDMAddress parameter
without triggering a new CSAT3 measurements. The CSAT() instruction
must be preceded by the SDMTrigger() instruction in order to used Options
97 - 99.

Description
90 Trigger and Get wind & speed of sound data
91 Trigger and Get wind & sonic temperature data
92 Trigger and Get wind & speed of sound data minus 340 m/s
97 Get wind & speed of sound data minus 340 m/s after a Group
Trigger
98 Get wind & sonic temperature data after a Group Trigger
99 Get wind & speed of sound data after a Group Trigger
CSAT3Opt The CSAT3Opt argument sets the CSAT3’s execution parameter. This
parameter tells the CSAT3 which measurement parameters to use and what
frequency to expect the measurement trigger from the datalogger. See the
table below for a brief description of each of the parameter and the CSAT3
manual for a detailed description.

Set Execution Parameter to 60 Hz to 20 Hz Oversample Mode
SDMAO4 (Source, Reps, SDMAdress)
This instruction is used to set the voltage to an SDM-AO4 four-channel analog
output device.
The SDMAO4 instruction has the following parameters:
Parameter
& Data Type
Enter
Source
Variable
The Source parameter is the variable that holds the voltage, in millivolts,
which should be sent to the SDM-AO4. If multiple SDM-AO4s are to be
triggered with one instruction, this parameter must be an array dimensioned
to the size of the Reps.
Reps
Constant or
Expression
The Reps parameter determines the number of SDM-AO4 devices to supply
a voltage using this instruction. The SDM-A04s must have sequential SDM
addresses if the Reps parameter is greater than 1.
