parallel DAQs

[Dennisatwork]

I want to communicate to two DAQs(in parallel) using one computer in CVI.

What is the function(s) I need to call to direct the DAQmx functions to one or the other DAQ?

Is it DAQmxGetDeviceAttribute() ? Do I control it via the task name?

Which DAQ system to address is set while you are creating a channel, either interactively in MAX or programmatically with DAQmxCreateXxChan functions. Channels are then added to an acquisition task, which could eventually acquire measures from more than one device at a time. If you want to keep devices separate and independent, you must simply avoid to mix channels coming from different boards.
