I would like to know if there's a way to control NI-9474 without using the cRIO chassis. I need its switching speed (1us) to carry 1.5A (1A per channel). I have a PXI system of 6259, 2566, DMM and PSU.
I just wanted to use the module, I hope anyone could help me.
With the hardware you currently own, it is not possible to use the 9474 without cRIO. Generally, it is possible to use the c-series module outside of cRIO. As you can see in the DAQmx read me file, the 9474 is supported by the DAQmx driver. As such, you are able to use this module in a Compact DAQ chassis (cDAQ-9172) by programming with DAQmx. The other option that you have is to use an R-series expansion chassis (cRIO-9151). You would need an R-series card in your PXI chassis that would interface with the 9151 chassis that contains your c-series module. I apologize that these do not seem like viable solutions for you, but I wanted you to know that they are options. Thanks,
