National Instruments Corporation

DAQ devices because it lets multiple devices operate at their peak

performance.

NI-DAQ also internally addresses many of the complex issues between

the computer and the DAQ hardware such as programming interrupts

and DMA controllers. NI-DAQ maintains a consistent software

interface between its different versions so that you can change

platforms with minimal modifications to your code.

Instrument Drivers

National Instruments distributes VXI

plug&play

instrument drivers free

of charge. VXI

plug&play

instrument drivers are one level above the

NI-DAQ device driver and contain high-level software functions whose

architecture is specified by the VXI

plug&play

Systems Alliance. The

VXI

plug&play

standards increase interoperability with other vendors,

and ensure that drivers are designed and presented in a consistent

fashion that facilitates ease of use. Refer to Figure 1-1 to see the

relationship between your software components.
