I am using Labview 7.1 Full Development, on Win2000, with a PCI-6251 M-series device, and i'm using DAQmx.
I would like to synchronize the acquisition of analog inputs with a quadrature encoder based on a digitial reference trigger (with a specified # of pretrigger samples) on PFI0.
Everything works well, except that i can't figure out how to use a reference trigger with the position counter. It keeps giving me the error # -200452 "Specified property is not supported by the device or is not applicable to the task. Property: Ref.TrigType"
Is it possible to synchronize the position counters with a *triggered* analog input acquisition?
I've searched everywhere and i can't find any documentation on this topic.
If i didn't want to have a triggered acquisition, then the synchronization works great, but my application requires that this acquisition be triggered.
Any advice or workarounds would be greatly appreciated!
Thanks.
