Chapter 2 Function Reference — SCAN_to_Disk
NI-DAQ FRM for PC Compatibles 2-318

when you enable pretrigger mode. If you do not apply the stop trigger, SCAN_to_Disk
eventually returns control to your application because you eventually run out of disk space.
In any case, you can use
Timeout_Config to establish a maximum length of time for
SCAN_to_Disk to execute.
Note Simultaneous sampling devices do not use the sampleRate parameter. Because
these devices use simultaneous sampling of all channels the scanRate parameter
controls the acquisition rate; therefore, a scanRate of 0 is not allowed.
