2-4 General Description KPCI-PIO24 User’s Manual
Bus control
The KPCI series of data acquisition boards use the AMCC S5933 PCI bus controller, which is
universally recognized as an industry standard. Its PCI bus interface includes all the components
necessary for optimal PCI bus utilization. The AMCC S5933 provides two modes of operation:
bus mastering and target. The KPCI-PIO24 normally only implements the target mode. The target
mode, also referred to as passthrough operation, provides a simple register access port to the PCI
bus. High speed data transfer via bus mastering is unnecessary for the simple digital I/O of the
KPCI-PIO24 board.
The KPCI-PIO24 maps these AMCC S5933 registers as a memory mapped peripheral, though
not all are used for operation of the KPCI-PIO24:
• All sixteen 32 bit operation registers (64 bytes total)
• All eight 32 bit specific functional registers
All memory addresses of registers are automatically assigned by the PCI bus Plug and Play
feature upon system power-up.
Software
The user can select a fully integrated data acquisition software package (e.g., TestPoint or
LabVIEW) or write a custom program supported by DriverLINX. DriverLINX software is
included with the hardware.
DriverLINX supports programmers who wish to create custom applications using Visual C/C++,
Visual Basic, or Delphi. DriverLINX accomplishes foreground and background tasks to perform
data acquisition. TestPoint is a fully featured, integrated application package with a graphical
drag-and-drop interface, which can be used to create data acquisition applications without
programming. LabVIEW is a fully featured graphical programming language used to create
virtual instrumentation.
Refer to Section 3, “Installation,” for more information about those programs.
