There really isn't anyway to fake having a DAQ board, and w/o a DAQ board, you're going to get errors when trying to communicate to it.
You can either:
1) Remove the hardware commands and use simulated dsta.

2) Use an "alternative DAQ" such as a serial/parallel port or even a sound card

3) Connect to the PC w/ the DAQ remotely to test the program (Remote Data Acquisition or RDA).
