    I/O lines. If you require more advanced triggering or additional I/O lines (either digital or analog), you can use the PCI-1408 and NI-IMAQ with the National Instruments data acquisition (DAQ) product line. A common problem with image acquisition boards is that you cannot easily synchronize several functions to a common trigger or timing event.

    Introduction Software Programming Choices You have several options to choose from when programming your National Instruments IMAQ hardware. You can use National Instruments application software such as LabVIEW, National Instruments image analysis software such as IMAQ Vision, or the NI-IMAQ driver software.

  • Page 15: Ni-Imaq Driver Software

    The NI-IMAQ software does not perform any image analysis. For image analysis functionality, refer to the National Instruments Application Software section earlier in this chapter. NI-IMAQ has both high-level and low-level functions for maximum flexibility and performance.
