How to synchronize two NI9215 DAQmx cards?

[_EMG_]

Hi there,

I'm using two NI9215 DAQmx cards (4ch simultaneous sampling analog inputs) in a chassis type cDAQ-9174.

Since I need to aquire 8 channels simultaneously I've two NI9215 cards.

My question is how do I configure these cards to be synchonized?

I'm using LabVIEW2009 SP1 Dev. Suite

Thanks for answers!

One of the beautiful things about CompactDAQ is that you can put multiple modules of the same time (Analog, Digital, etc.) into the same task and they are automatically synchronized.  So, to synchronize the two modules, create one Analog Input task and reference the channels as "cDAQ1Mod1/ai0:3, cDAQ1Mod2/ai0:3".  This will automatically synchronize the two modules together.
