Finally, I have programmmed all the step and i can do data acquisition. But there is a problem, i have a limit of 200 Hz. In fact, if frequency is more important than this limit, the file (where there is data) is more important and have some false value. If someone have an explain to this phenomen , i accept it with pleasure.

I had to acquier data from 3 DIO-32HS in synchronising the acquisition with "change detection". Next i had to write these data in a file. It is for this second step, i have some difficulties (for the first, i took one of the example, an i adapted it). For example, I don't exactly know, if i had to work with a circular buffer, or with a normal, or if i must change my parameters of synchronisation(to increase frequency, ....) Oups, i forget saying that i must work in continue at a 2 kHz frequency. So, if you have an idea to begin or more, thanks to answer.

I have three PCI-DIO- 32HS and i had to read data from these cards when one of the bit of the second card change of level. Do you know how i had to do ? When there is only one card, it is not a problem, we can use one of the property of DIO.config.vi, but I don't know how trigger the two others. Thanks.
