cRIO 9237 and NI 9944

[Jimmy P]

I have read the "NI 9945 and NI 9237 Connection Guide" and it looks like it is for cRIO. This is in fact what I am using. In MAX, I tried to add a global virtual channel and it takes me through analog signals >> analog input >> strain. However the NI 9237 module connected to cRIO does not show up on the menu. The only hardware I can see here are under the category "physical" and that is all. I'm trying to calibrate and configure the strain gauges. Is this how I would do this or does using Real Time and FPGA take care of offset and null? If RT and FPGA do this, how do I configure the program in the block diagram?

Thank you,
Jimmy

Hi Jimmy,

Thanks for contacting National Instruments.  I have been looking into your question and it looks like the reason that you are not seeing the NI 9237 module when trying to set up the global virtual channel is because you are using the 9237 module with a cRIO and the connection guide that you are looking at involves using this module with a cDAQ chassis.  The global virtual channels only apply to modules that are listed as DAQmx devices inside of MAX and this module will not be one of those when using it in a cRIO chassis.  The best direction that I can point you in will be to look at an example in LabVIEW by going to Help>>Find Examples.  The name of the example that I believe will help you out is "NI 9237 Getting Started.lvproj."  You can find this example by going to the "Search" tab and typing in "9237."  I hope this helps and if you have more questions about the same issue, feel free to reply back.  Thanks!
