NI-DAQ FRM for PC Compatibles

apply a pulse at the STOPTRIG* input of the MIO-16/16D or the EXTTRIG* input of 
the AT-MIO-16F-5, AT-MIO-64F-5, or AT-MIO-16X or the EXTTRIG input of Lab and 
1200 Series devices, NI-DAQ acquires an additional number of data points specified by 
ptsAfterStoptrig before the acquisition terminates. 

DAQ_Check

 or 

Lab_ISCAN_Check

 will 

rearrange the data into chronological order (from oldest to newest) and return with the status 
parameters equal to one when called after termination.

Calling 

DAQ_StopTrigger_Config

 with stopTrig set to 0 returns the acquisition mode to 

its default, acyclical setting.

You cannot use pretrigger mode in conjunction with the external conversion method on the 
MIO-16/16D devices.

(E Series devices only) If you use this function with stopTrig = 1, the device uses an active 
high signal from the PFI1 pin as the stop trigger. This selection is consistent with the 
MIO-16/16D boards. After calling this function, you can use the 

Select_Signal

 function 

to take advantage of the DAQ-STC signal routing and polarity selection features.
