No devices detected

I am running a 7831R DAQ. I followed the software installation order. I installed labview 7.1 first, then the drivers, and the FPGA module. When I go to build a VI, and want to prompt for a analog input using the DAQ assistant, no physical devices were found. For other DAQs, I saw disscussions referring to downloading a DAQmx file, but my model, the 7831R was not listed. Any ideas? Thanks,
Gregg

Hello Gregg,

The 7831R board doesn't use the DAQ driver. Even though it is used for Data Acquisition, it is not really a DAQ board. It is an FPGA board. So the driver that it uses is the NI-RIO. The DAQ Assistant uses DAQmx driver which is not used for the FPGA boards.
For the FPGA boards you need to use the Device I/O VIs when targeted to the FPGA. Please remember that when using a RIO (Reconfigurable I/O) board you need to create a VI for the FPGA and most of the time, another VI for the host computer that will communicate to the FPGA VI.
Thank you
