This manual is available from National Instruments by request. If you are using NI-DAQ, LabVIEW, or LabWindows/CVI, you should not need the register-level programmer manual.
  • Page 11 SCXI chassis kit. About the SCXI Chassis The SCXI-1000, SCXI-1000DC, and SCXI-2000 are four-slot SCXI chassis and the SCXI-1001 is a 12-slot SCXI chassis. All the chassis house National Instruments SCXI modules. The SCXI-1000, SCXI-1001, and SCXI-2000 chassis are powered with standard AC power.
  • Page 12 NI-DAQ for PC compatibles Your computer Software Programming Choices There are several options to choose from when programming your National Instruments plug-in DAQ and SCXI hardware. You can use LabVIEW, LabWindows/CVI, NI-DAQ, or register-level programming. LabVIEW and LabWindows/CVI Application Software LabVIEW and LabWindows/CVI are innovative program development software packages for data acquisition and control applications.

  • Page 14 Chapter 1 Introduction 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. Even if you are an experienced register-level programmer, consider using NI-DAQ, LabVIEW, or LabWindows/CVI to program your National Instruments DAQ hardware.
