  • Page 13: About The 611X E Boards

    The 611X E board is a completely switchless and jumperless data acquisition (DAQ) board for the PCI bus. This feature is made possible by the National Instruments MITE bus interface chip that connects the board to the PCI I/O bus. The MITE implements the PCI Local Bus Specification so that the interrupts and base memory addresses are all software configured.

  • Page 14: What You Need To Get Started

    To set up and use the 611X E board, you will need the following: Software Programming Choices You have several options to choose from when programming your National Instruments DAQ and SCXI hardware. You can use National Instruments application software, NI-DAQ, or register-level programming.

    LabVIEW Data Acquisition VI Library, a series of VIs for using LabVIEW with National Instruments DAQ hardware, is included with LabVIEW. The LabVIEW Data Acquisition VI Library is functionally equivalent to NI-DAQ software. LabWindows/CVI features interactive graphics, state-of-the-art user interface, and uses the ANSI standard C programming language. The...

  • Page 16: Figure 1-1. The Relationship Between The Programming Environment

    NI-DAQ driver software, as illustrated in Figure 1-1. Register-Level Programming The final option for programming any National Instruments DAQ hardware is to write register-level software. Writing register-level programming software can be very time-consuming and inefficient, and is not recommended for most users.

    The 611X E board can measure and correct for almost all of its calibration-related errors without any external signal connections. Your National Instruments software provides a self-calibration method. This self-calibration process, which generally takes less than a minute, is the preferred method of assuring accuracy in your application. Initiate self-calibration to minimize the effects of any offset, gain, and linearity drifts, particularly those due to warmup.

Programming the DMA controller and servicing interrupts can take several milliseconds in some cases. During this time, data accumulates in the FIFO for future retrieval. With a larger FIFO, longer latencies can be tolerated. In the case of analog output, a FIFO permits faster update rates, because the waveform data can be stored in the FIFO ahead of time.
