DAQ (4474) : reading the buffer only when it reachs a defined size ?

[Math_]

Hello,

I need help with a DAQ device (4474).

I want to start a finite acquisition (256 samples@44KHz) every time I have a rising edge of an external trigger. I want to be able to read my buffer after 5 rising edge of the trigger (for exemple). So, I will read 256 * 5 = 1280 Samples.

Any suggestions on how to code that thing with DAQ ?

Thx !
