mlusmore001, In order to load in a spread sheet file (for example tab delimited) you should use the all functions>File I/O>Read From Spreadsheet File.vi. This VI will allow you to load the data in from file, you can also specify a different delimiting character. Then depending on the number of columns in your spreadsheet use the index array function to extract a column. You will then be able to pass this data to the DAQ assistant express VI or use the traditional DAQ VIs to output the data through the DAQ card.
I hope this helps Tristan J Applications Engineer National Instruments
