Using RTSI With the DAQ Assistant?

[tritone]

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. I hit "Run" and nothing happens, and I have to use the Abort button to stop execution. It works great if I don't specify any sort of triggering options, however I need the cards to be synchronized. I have an RTSI cable installed, and it is shown in MAX also.

Do I need to set this up under the "trigger" tab instead? Any help would be GREATLY appreciated! Thanks!

Hi,

I have not used DAQ Assistant before. But maybe you can look under Help/Find Examples/Hardware Input and Output/DAQmx/Synchronization/Multi-Device/Muti-Device Synch-Shared Timebase-Finite(or Cont) Acqusition.vi.

The examples demonstrate how to acquire a finite (or continous) amount of data (Waveform) using the DAQ device's internal clock. It also shows how to share a timebase between two devices using RTSI.

Hope this helps,
Dan

The assistant won't allow you to synchronize multiple boards. Dan's suggestion is the best to use the existing example.
