Retrigger in M-Series possible ?

[Triple]

Hi,

since I am not able to acquire a number of sample sets with a NI PCI-6224 (M-Series) where each sample set should be started by a digital trigger : Is this card retriggerable at all ?

I tried to modify the example from the traitional DAQ : Acquire_N_-_Multi-Digital_Trig.zip (NI Developer zone) to DAQmx but did not get the code to acquire more than one sample set that starts really by the trigger itself.

Thanks,

Dirk

Dirk,

the trigger circuitry of the M-Series boards is not retriggerable but you can use the same "trick" that you can use with the E-Series board by using the counters of the board to create a retriggerable pulse-train that can be used as the analog input scanclock.
There is an example called "Multi-Function-Ctr Retrigg Pulse Train Generation for AI Sample Clock.vi" that ships with DAQmx that does exactly what you are looking for.
