generating a TTL signal using NI-DAQ

[MABADIE63]

I’m currently trying to generate a TTL signal using LabVIEW with a NI 9263 module. The goal is to simulate a digital trigger signal that can be used to control a high-voltage power supply, specifically the 10HVA24-BP1 model

thx in adavance

Hi Mabadie,

and what is your question/problem?

[MABADIE63]

to make it simple i don't know how to do, like you see i've tried but when i start the program the DAQ sent 8 signals

You set the AO regeneration to Continues mode. (Echantillon Continus) This means DAQmx will regenerate the pulse until the DAQ task is stopped (or closed). Set that to Finite Sample or whatever it is called in French. You may also have to set the Regeneration mode explicitly, always a good thing is to use the Example Finder and go through the various samples that it will present you to get an idea how to do things in DAQmx.
