For the above explained application we are using NI USB-8451.
Now for reading the data , should i use VISA vis or DAQmx VIs.

HI
How can we configure the spi frequency of operation for NI-USB-8451
I am developing a testing tool which requires the data to come from PC instead of a card reader which speaks to the testing device on spi.
however different card readers speak on different spi frequency and i need that to be configurable. Can this be done in lab view. And I need some more i/o signalling along with the spi. Is this possible.

The 8451 SPI frequency is set the "NI-845x SPI Script Clock Rate" VI. Check out Chapter 8 of the software manual.
In terms of "more I/O signaling" the 8451 has 8 general purpose digital I/O lines. This information is in the User Guide and Specifications.
