    Chapter 1 Introduction This chapter describes the VXIpc-486 Model 200 Series kit for Microsoft Windows, lists what you need to get started, and lists optional equipment and software. The VXIpc-486, an embedded computer based on the Industry Standard Architecture (ISA), is a high-performance, easy-to-use platform for VXIbus systems, featuring complete VXI functionality through interactive utilities and C function calls.

  • Page 15: Optional Equipment

    • LabVIEW for Windows/Sun VXI Instrument Library If you want to use LabWindows with your VXIpc-486, you can order either the LabWindows for DOS, VXI Development System, or the LabWindows/CVI for Windows, VXI Development System. The LabWindows for DOS, VXI Development System contains the following components.

  • Page 16: Hardware Description

    The VXIpc-486 Series computers are custom VXI computers that you install directly in your VXI mainframe to achieve the smallest possible physical size for a VXI system. An embedded computer can take full advantage of the VXI high-performance backplane capabilities and give you direct control of VXI registers, memory, and triggers.

    Non-Slot 0 Configurations If you will be installing the VXIpc-486 Model 200 Series in any slot other than Slot 0, use either configuration E or F. As a Non-Slot 0 device, the VXIpc-486 accepts the CLK10 signal from the backplane.

  • Page 22: Modid Signal Termination

    W7 configures the System Controller for Slot 0/Non-Slot 0 operation. When configured for Slot 0 operation (Figure 2-3a), W7 enables the VXIpc-486 Model 200 Series System Controller functions (SYSCLK and SYSRESET drivers, the Bus Arbiter and Bus Timer). When configured for Non-Slot 0 operation (Figure 2-3b), W7 disables the System Controller functions.

    How can I determine which version of the NI-VXI software I have installed? Run the NI-VXI interactive control utility program, either VIC or VICTEXT. (If you run VIC, stay in the Text Window.) At the prompt type ver, and the program will display the versions of VIC/VICTEXT and NI-VXI, and the hardware revision of the VXIpc-486 that the NI-VXI software supports.
  • Page 84 To test individual devices, you can use the VIC or VICTEXT program to interactively issue NI-VXI functions. You can use the VXIin() and VXIout() functions or the VXIinReg() and VXIoutReg() functions to test Register-Based devices by programming their registers. If you have any Message-Based devices, you can send and receive messages with the WSwrt() and WSrd() functions.

You need to have the monitor attached at boot time to get color. © National Instruments Corporation VXIpc-486 Model 200 Series for MS Windows...
  • Page 86 I configure my VXIpc-486? The VXIpc-486 Model 200 Series computers use the Chips & Technology 451 video chip set, which is compatible with the Standard VGA video output MS Windows video driver. Super VGA is available for VXIpc-486 computers in the Model 500 Series but it cannot be used for the Model 200 Series.
  • Page 87 To add more RAM to the VXIpc-486, you need have to change the SIMMs that reside in slots A1 and A2 of the VXIpc-486. The SIMMs used for the VXIpc-486 Model 200 Series differ from those used for the Model 500 Series. The maximum amount of RAM on a VXIpc-486 Model 200 Series is 16 MB.
  • Page 88 The VXIpc-486 needs upper memory from C800h to CFFFh and from E000h to EFFFh so that it can access the devices in VXI address space. See Appendix G, VXIpc-486 Hardware Configuration for information on the available port I/O register space, upper memory area, interrupts, and DMA channels.

Run the VXI Resource Editor program, either VXIEDIT or VXITEDIT, and select the Configuration Editor. 3. In the Logical Address Configuration Editor, change the Logical Address parameter from 0 to a non-zero value.
