The contents of the SCXI-1121 kit (part number 776572-21) are listed as 
follows:

If your kit is missing any of the components, contact National Instruments.

This manual contains complete instructions for directly programming the 
SCXI-1121. You can order separate software packages for controlling the 
SCXI-1121 from National Instruments.

When you combine the PC, AT, and MC data acquisition boards with the 
SCXI-1121, you can use LabVIEW for Windows or LabWindows for DOS. 
LabVIEW and LabWindows are innovative program development software 
packages for data acquisition and control applications. LabVIEW uses 
graphical programming, whereas LabWindows enhances Microsoft C and 
QuickBASIC. Both packages include extensive libraries for data 
acquisition, instrument control, data analysis, and graphical data 
presentation.

Your National Instruments data acquisition board is shipped with the 
NI-DAQ software. NI-DAQ has a library of functions that you can call from 
your application programming environment. These functions include 
routines for analog input (A/D conversion), buffered data acquisition 
(high-speed A/D conversion), analog output (D/A conversion), waveform 
generation, digital I/O, counter/timer, SCXI, RTSI, and self-calibration. 
NI-DAQ maintains a consistent software interface among its different 
versions so you can switch between platforms with minimal modifications 
to your code.

You can also use the SCXI-1121, together with the PC, AT, and MC data 
acquisition boards, with NI-DAQ software for DOS/Windows/
LabWindows/CVI. NI-DAQ software for DOS/Windows/
LabWindows/CVI comes with language interfaces for Professional 
BASIC, Turbo Pascal, Turbo C, Turbo C++, Borland C++, and Microsoft C
