Is it possible to synchronise two USB DAQ cards

[viswa]

Hi all,

               I have a USB6221 and USB6229 DAQ cards. I want to implement two different DAQmx tasks using these two cards in sync. Please follow the thread to see my problem(http://forums.ni.com/ni/board/message?board.id=250&thread.id=53046). To resolve the problem i would like to synchronise the DAQ boards.

If any body has idea please let me know.

Hi viswa,

There is an article on the NI Developer Zone that describes how synchronize multiple USB Data Acquisition devices. If you scroll down to the section headlined Multi-Device Synchronization there should be a screenshot of a VI. This VI should programmatically synchronize your devices. The article also has a diagram detailing how to wire the two devices together.

Have a go with that, if you have any problems then post again and I'll help you out.

Kind Regards,
