 DAQ using one PC but two carts simultaneously

How can I do a DAQ, using one computer but two different carts, in the
same time? is there any example about?

Do you mean two different cards?  Because NI-DAQ (theoretically) makes
that pretty much transparent.  Of course, it gets more difficult if
you're talking about true simultaneity in sampling.

If you do mean carts, it'd be easier to answer if you told us what was
on your carts :)

Greetings,

It is quite simple to use two different DAQ cards in the same computer
at the same time.  The key to the task is synchronizing the two
devices.  This is accomplished using the RTSI bus.  Below is the link
to a tutorial which discusses Advanced Synchronization Techniques for
Data Acquisition:

Examples are definitely available to demonstrate the use of multiple
devices simultaneously.  If the two DAQ cards are E-Series, the
examples are shipped with labview and located in Hardware Input and
Output >> DAQ >> Multiple Devices.  This path refers to LabVIEW 6.1,
but these examples are also available in previous versions under
different paths.  Examples for other DAQ cards are available on NI's
Web Site at the following location:

Good luck with your application.
