Hello!
Basicaly the PXI Bus (backplane) provides to share trigger and timing signals between the devices.
To do this, first you have to identify your PXI-System within the MAX (Measurement&Automation Explorer).
Then you can use the attached VI, which is a example for synchronize two AI, to build your application in the same way!
There are different ways to start AI synchronously, e.g for internal/external Trigger and to share clocks and rates, to get
sure they are running synchronously. You can search for examples under .../LabVIEWx.x/examples/DAQmx/Synchronization/MultiDevice.llb
Try the following example (for LabVIEW 8.x), if you have any questions further on, please post again!

Hi!
I'm sorry, i didn't kept the 4351 in mind while answering!
No, it's not possible to synchronize the 4351 via PXI, because it has no RTSI-Bus and only works with traditional DAQ.
So the only way would be to share the M-Series clock via a PFI Pin and try to use it as external trigger/timing for the 4351, but i didn't tried something like this!
Regards, Christian

Thanks Christian, that was my suspicion.
Also to start acq in sync with M series device, triggering AI acq from an M series device via one of the digital Input lines should be possible in this device, but not sure how close will it be to a PXI back-plane synchronised scenerio
