DAQmx Read (Analog DBL 1Chan 1Samp) VI needs timing when it never has before?

[BrooksSRK]

I am using LV 2026 Q1. I replaced a 6212 with a 9178 chassis and several cards including a 9202 AI card.  I am getting an error I have never seen before. If I put a DAQmx timing vi before the read the error goes away. Not sure why I would suddenly need timing for a simple read. Please see screen shot. I am confused. Any help would be appreciated. 

Thx

Steve

Hi Steve,

the NI6212 is a simple multifunction DAQ device, while the NI9202 is a simultaneous AI card using a DeltaSigma ADC.

That ADC doesn't support "on demand" samples, it requires a sample rate defined by that huge list in the NI9202 specs!

So your question is answered by "RTFM!"… 😄

Thanks, I thought I did, but I guess not close enough.  Thanks for the response. Greatly apreciated.
