Configuration of multiple PCI-6110 boards for simultaneous sampling using LabVIEW.

[nasanole]

I am in the process of writing a LabVIEW program for acquiring multiple microphone signals. I am using a PC that has 3 PCI-6110 boards in it and I was wondering if it was possible to configure the boards in such a manner that they all sample at the same time. I believe that RTSI may be the way to go but I'm not very familiar with it--yet. Any suggestions would be appreciated. Thank you.

Yes i think that RTSI would be the best option to go with. So one board will act as master and will generate the CLK signal and pass that CLK over to the two slave boards. You can also have three boards start the acquisition at the same time using a trigger pulse on the master board and passing the trigger signal to the slaves over RTSI as well.
Here are links to two examples in labview that you might find helpful.

Happy coding!!

all the listed examples are for E series cards only.

This is a problem as I cannot find too many S series examples.
