Synchronising Sampling Across Multiple X-Series Cards

http://digital.ni.com/public.nsf/allkb/78E44565FD87E7D686257108007F94F8 

 

talks about synchronising data acquisition across X-series cards in a PXI rack by specifying a comma separated list of physical channels when creating the DAQmx task.

 

I need to add individual custom scales and min/max input values for each of my inputs.  

 

If I have a number of DAQmx Create Channel blocks connected together to add physical channels to the same task, will acquisition of these physical inputs be automatically synchronised?  Will DAQmx work it out "intelligently" in the same way as if I'd presented a comma separated list of channel names to a single Create Channel block?  Or do I need to resort to the more complex method shown in the article?

 

Cheers,

 

Andy

Hi Andy,

 

Yes, DAQmx will work it out. The important part is to add all of the channels to the same task, and chaining the task wire through multiple DAQmx Create Channel VIs will do that.
