Finally, verify that your code is correct. For reference, see the
examples described in the NI-SWITCH Software User Manual.
The NI-SWITCH driver also ships with several examples in source
code. Compare your algorithm to the ones in the examples.

Do I need to program the switch card myself?

The NI 2565 comes with the NI-SWITCH driver software, which exports
the full functionality of the card. NI-SWITCH handles the complex issues
of direct memory access, interrupts, and operating system interfacing.
