Parameter
& Data Type
Enter
Command 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.
Code 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
Rate The Rate 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.

12 Set Execution Parameter to 12 Hz
20 Set Execution Parameter to 20 Hz
30 Set Execution Parameter to 30 Hz
60 Set Execution Parameter to 60 Hz
61 Set Execution Parameter to 60 Hz to 10 Hz Oversample Mode
62 Set Execution Parameter to 60 Hz to 20 Hz Oversample Mode
INT8 (Dest, Address, Config8_5, Config4_1, Funct8_5, Funct4_1,
OutputOpt, CaptureTrig, Mult, Offset )
This Instruction allows the use of the SDM-INT8, 8 Channel Interval Timer,
with the CR5000. The INT8 is a (S)ynchronous (D)evice for the
(M)easurement of intervals, counts between events, frequencies, periods,
and/or time since an event. See the INT8 manual for more information about
its capabilities.
