  • Page 12: Introduction

    This chapter introduces you to MXI-2 and your MXI-2 kit. How to Use This Manual The factory default settings for your MXI-2 hardware are suitable for most typical applications. You may need this manual only to follow the installation instructions for each board. To try another configuration, use this manual for instructions on changing your hardware settings.

  • Page 13: Mxi-2 Description

    Because MXI-2 incorporates all these new signals into a single connector, the triggers, interrupts, and utility signals can be extended not only to other chassis but also to the local CPU in all MXI-2 products using a single cable. Thus, with MXI-2, CPU interface boards such as the PCI-MXI-2, PCI-MXI-2 Universal, and PXI-8320 perform as if they were plugged directly into the VXI/VME backplane.

  • Page 14: Hardware Description

    PCI-based computer. (The PCI-MXI-2 is for 5 V PCI systems, while the PCI-MXI-2 Universal is for 5 V or the newer 3.3 V PCI systems.) The PXI-8320 is a 3U-size, PXI/CompactPCI-compatible circuit board that plugs into one of the peripheral slots in your PXI/CompactPCI chassis.
  • Page 15 The C-size VXI-MXI-2 is housed in a metal enclosure to improve EMC performance and to provide easy handling. The B-size module does not require this enclosure. Unless otherwise noted, the term VXI-MXI-2 refers to both the C-size and B-size Note modules.

    The PCI-MXI-2 can accommodate one 72-pin DRAM SIMM. Table 2-1 lists the SIMM types you can use. You can use a 32- or 36-bit SIMM because DRAM parity is not required. The PCI-MXI-2 can hold up to 16 MB of onboard memory. The PCI-MXI-2 supports DRAM speeds of 80 ns or faster.

    However, you must remove the enclosure if you want to change the amount of DRAM installed on the VXI-MXI-2. Switch S6, which is directly related to the amount of DRAM you want to install, is also accessible only by removing the enclosure.
  • Page 33 (location designator U43) on the panel. The down position of the DIP switch corresponds to a logic value of 0 and the up position corresponds to a logic value of 1. Verify that the VXI-MXI-2 does not have the same logical address as any other statically configured VXIbus device in your system.

  • Page 34: Vxibus Slot 0/Non-Slot 0

    Figure 5-2. Logical Address Selection VXIbus Slot 0/Non-Slot 0 The VXI-MXI-2 is configured at the factory to detect if it is installed in Slot 0 of a VXIbus chassis automatically. With automatic Slot 0 detection, you can install the VXI-MXI-2 into any VXIbus slot.

  • Page 35: Vxibus Clk10 Routing

    CLK10 signal. VXIbus CLK10 Routing When you install it in Slot 0 of your chassis, the VXI-MXI-2 supplies the VXIbus CLK10 signal. The VXI-MXI-2 can use three different sources to generate this signal: an onboard oscillator, the external CLK SMB connector, and the MXIbus CLK10 signal.
  • Page 36 You must configure these switches as shown when using the corresponding CLK10 source setting of W3. You can also configure the VXI-MXI-2 to drive the external CLK SMB signal from the VXIbus CLK10 signal. Switch S3 controls whether the VXI-MXI-2 drives or receives the external CLK SMB signal.
  • Page 37 Chapter 5 VXI-MXI-2 Configuration and Installation When switch S3 is set so that the VXI-MXI-2 receives the SMB CLK10 signal, you have the option to add a 50 Ω termination to the signal by setting switch S4. S4 is unused—its setting does not matter—when S3 is configured to drive the external CLK SMB signal.

  • Page 39: Trigger Input Termination

    Chapter 5 VXI-MXI-2 Configuration and Installation The VXI-MXI-2 can also drive or receive the MXIbus CLK10 signal. Switch S7 controls whether the VXI-MXI-2 drives MXIbus CLK10 from the VXIbus CLK10 or receives MXIbus CLK10. As shown in Figure 5-4c, if W3 is configured to use the MXIbus CLK10 to generate the VXIbus CLK10 signal, switch S7 must be configured to receive MXIbus CLK10.

  • Page 40: Mxibus Termination

    MXIbus. Any MXIbus devices in the middle of a MXIbus daisy chain must not terminate the MXIbus. The VXI-MXI-2 automatically senses whether or not it is at either end of the MXIbus cable to terminate the MXIbus. You can manually control MXIbus termination by defeating the automatic circuitry.

  • Page 41: Configuration Eeprom

    Chapter 5 VXI-MXI-2 Configuration and Installation Use switch 2 of U35 to select whether the VXI-MXI-2 automatically controls termination of the MXIbus. Notice in Figure 5-8a that switch 1 has no effect when switch 2 is set for automatic MXIbus termination. To control termination manually, you must turn off switch 2.
  • Page 42 This is useful in the event that the user-configured half of the EEPROM becomes corrupted in such a way that the VXI-MXI-2 boots to an unusable state. The Change Factory Configuration switch (switch 3 of U35) lets you change the factory-default configuration settings by permitting writes to the factory settings section of the EEPROM.

  • Page 43: Onboard Dram

    Figure 5-9. EEPROM Operation Onboard DRAM The VXI-MXI-2 can accommodate up to two 1.35 in. 72-pin DRAM SIMMs. You must remove the metal enclosure to access the SIMM sockets and a switch that selects the SIMM size. To access these components, remove the four screws on the top, the four screws on the bottom, and the five screws on the right-side cover of the metal enclosure.
  • Page 44 Use Bank 0 first when installing the SIMMs, and use Bank 1 when you need to install a second, matching SIMM. As shown in Table 5-1, you can install up to 64 MB. The VXI-MXI-2 supports DRAM speeds of 80 ns or faster.

    Chapter 6 VXI-MXI-2/B Configuration and Installation Configuration EEPROM The VXI-MXI-2/B has an onboard EEPROM, which stores default register values that are loaded at power-on. The EEPROM is divided into two halves—a factory-configuration half and a user-configuration half—so you can modify the user-configurable half while the factory-configured half stores a back-up of the factory settings.

  • Page 93 Controlling the EEPROM Operation Use switch 1 (FOV) of the four-position switch (at location U17 on the PCI-MXI-2, SW1 on the PCI-MXI-2 Universal, or U6 on the PXI-8320) to control the operation of the EEPROM. Switch 1 determines whether the PCI-MXI-2, PCI-MXI-2 Universal, or PXI-8320 boots from the factory-configured half or the user-configurable half.
  • Page 94 Power off your computer or chassis. Caution To protect both yourself and the chassis from electrical hazards, leave the computer or chassis off while you change the settings on the PCI-MXI-2, PCI-MXI-2 Universal, or PXI-8320 module. Remove the PCI-MXI-2, PCI-MXI-2 Universal, or PXI-8320 from your PCI-based computer or PXI/CompactPCI chassis.

  • Page 96 Instruments, relating to our involvement with both the VXI Consortium and the VXIplug&play Systems Alliance. NI-VXI/NI-VISA If you ordered your MXI-2 hardware as part of a kit such as the VXI-PCI8000, you also received the NI-VXI/NI-VISA bus interface software. This software consists of interface-independent software (NI-VISA) for certain platforms addressed by VXIplug&play standards,...
  • Page 97 The bulk of this manual describes how to use hardware jumpers and switches to configure your MXI-2 boards. However, you can handle a substantial portion of your configuration task through the interactive configuration utilities that come with NI-VISA/NI-VXI. Refer to your getting started manual for more information about the NI-VISA/NI-VXI software.
  • Page 98 NI-VISA/NI-VXI software installation. LabVIEW, Measurement Studio, and LabWindows/CVI integrate the VXI and VISA libraries that are required to support your PCI-based MXI-2 products. You also get hundreds of complete instrument drivers, which are modular, source-code programs that handle the communication with your instrument to speed your application development.
