Using RTSI With the DAQ Assistant?

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?

Currently, the DAQ Assistant doesn't support synchronization of multiple devices. You'll have to use the API directly to accomplish this. Look at the Multi-Device Synch-Shared Timebase-Cont Acquisition.vi shipping example inside of Multi-Device.llb to see how this can be accomplished.
