Hello,
If you are using LabVIEW 6.1, use the Example Finder (Help>>Find Examples...) and search for simultaneous. You'll find "Simul AIAO Buffer(1200).vi" which should get you started.
If you're in an earlier version of LabVIEW go to examples\daq\anlog_io\anlog_io.llb to find the same example.
Regards,
Doug
