How to synchronize signal generation in three different modules(cDAQ)

[Kumar_B]

I am using cDAQ (USB type) -9178 chassis with two NI-9264 & one 9265 cards. I am generating three different signals for 3sec duration on all the three cards. How to synchronize all the three cards signal generation ?  I am attached the code .I am using LabVIEW 2009.

Hi Kumar,

Your attached VI creates three different tasks, one for each module.  The cDAQ-9178 only supports one continuous analog output task at a time, and in order to synchronize them, you want all the modules in the same task anyway.  Create one task and call DAQmx Create Channel sequentially for the channels from each module.
