Hello, I am trying to synchronize 3 PCI-6052E cards via RTSI using LABView and the DAQ Assistant VI. I have set one card's (the master's) clock source as "Internal", and the other two to "External" and "RTSI0", however this doesn't work. Does anyone have an example or a way to set this up? And do my DAQ Assistant VIs need to be in a while loop, or can I wire them into an "AI Waveform 2D Read" type of VI?
