2. 4. 5. 4 DAQconfig

This function configures the acquisition of words
reading modes:
Blocking: Using the function
a blocking function that is released when the amount of words specified in DAQ-
points is acquired or when timeout elapses. This mode is enabled when a call-
back function is not specified (it is set to null).
Non-blocking: The user specifies a callback function which is called whenever
the DAQeventDataReady event is signaled or when
timeout elapses. In the latter condition, there may be words available, but less than the amount
specified in DAQpoints.

DAQ to configure
Trigger mode
(number of samples that trigger is delayed (or advanced if negative))
Number of acquisition cycles. Each cycle requires a trigger specified by triggerMode.
A negative number means continuous acquisition
