Specifying input limits for multi-channel DAQ

[KoenVDA]

Now that I am using the DAQmx on Vista, I had to convert old LabVIEW programs. One thing I could not figger out till now is how to specify individual input limits for a multi-channel data acquistion. I need to acquire two voltage signals (sample rate specified, number of samles too, triggered on the first one) with potentially huge difference in magnitudes. Formarly, I used "AI waveform scan". It allows to set the input limits for each chanel individually. Now, the only thing I could find in the new examples is: "Cont Acq&Graph Voltage-Analog SW trigger.vi", but it uses the same maximum value and Minimum value for all channels. Is there an elegant alternative/solution ? Best regards, Koen

You use a separate DAQmx Create Channel function for each range you want, passing the task between them. Or you use a for loop and pass an array of channels and settings. To see this, create a DAQ Assistant task with multiple channels and open the block diagram.
