National Instruments Software

National Instruments has developed several software kits you can use with the NI VXIpc-882. NI-VISA and NI-VXI are already installed on your hard drive; LabVIEW is optional.

Chapter 1 Introduction

NI-VISA is the National Instruments implementation of the VISA specification. VISA is a uniform API for communicating and controlling Serial, GPIB, VXI, and VME instruments. This API aids in the creation of more portable applications and instrument drivers.

NI-VXI is the name of the National Instruments VXI bus control library. You can create applications using NI-VXI to control both VXI and VME devices. NI-VXI gives you complete VXI/VME functionality, including an API for performing basic VXI/VME data transfers and handling VXI/VME interrupts as well as VXI-specific functionality, such as doing message-based communication and handling VXIbus triggers.

The NI-VISA/NI-VXI software includes an interactive configuration and troubleshooting program, libraries of software routines for test and measurement (T&M) programming, interactive control programs for both NI-VISA and NI-VXI, a logging utility you can use for debugging your applications, and a VXI Resource Manager. You can use this software to seamlessly program multiple-mainframe configurations and have software compatibility across a variety of controller platforms.

Chapter 1 Introduction

You can also use the National Instruments LabVIEW application program and instrument drivers to ease your programming task. This standardized program matches the modular virtual instrument capability of VXI and can reduce your VXI software development time. This program features extensive libraries of GPIB, Serial, and VXI instrument drivers written to take full advantage of direct VXI control. LabVIEW includes all the tools needed for instrument control, data acquisition, analysis, and presentation.

LabVIEW is an easy-to-use, graphical programming environment you can use to acquire data from thousands of different instruments, including IEEE 488.2 devices, VXI devices, serial devices, PLCs, and plug-in data acquisition boards. After you have acquired raw data, you can convert it into meaningful results using the powerful data analysis routines in LabVIEW. LabVIEW also comes with hundreds of instrument drivers, which dramatically reduce software development time, because you do not need to spend time programming the low-level control of each instrument.

ExpressCard/34

This section provides information on the installation and removal of ExpressCard/34 modules.

Installing an ExpressCard/34

You can install an ExpressCard/34 module while the NI VXIpc-882 is running. The NI VXIpc-882 will automatically detect the card. ExpressCard/34s are generally marked with a symbol or a label to indicate which end to insert into the slot. The cards are keyed to prevent incorrect insertion.

To install an ExpressCard/34, complete the following steps.

1. Hold the card so the top side is facing left.

2. Insert the card until it is completely seated in its connector. The connector has an automatic eject mechanism. If you insert the card and it is ejected, simply re-insert the card until it is seated.

If you encounter too much resistance, do not force the card. Check the card orientation and try again.

Chapter 2 Installation

The NI VXIpc-882 will automatically recognize the ExpressCard/34 and load the appropriate driver(s). Third-party cards may require that you install additional drivers. Contact your ExpressCard/34 vendor for more information.

Caution The ExpressCard/34 interface is ESD sensitive. An electrostatic shock on the

ExpressCard/34 module while it is inserted may cause the controller to lock-up or reboot.

Removing an ExpressCard/34

To remove the ExpressCard/34 module push in the module and then release to eject the card. Slide the card out of the slot.

Caution To avoid data loss and other potential issues, stop communication with your

ExpressCard/34 device before removing it from the NI VXIpc-882. In Windows, use the Safely Remove Hardware tool to safely stop the ExpressCard/34.

Slot 0 Detection

The NI VXIpc-882 controller is configured at the factory to automatically detect if it is installed in Slot 0 of a VXI mainframe. With automatic System Controller slot detection the NI VXIpc-882 controller can be installed in any VXIbus slot.

The NI VXIpc-882 controller can be manually configured for either System Controller or Non-System Controller operation by defeating the automatic detection circuitry. Use the three position jumper J2 as shown in Figure 3-2 to select between automatic detection, System Controller, or Non-System Controller.

than Slot 0. When installing into a slot other than Slot 0, first reconfigure it as either a Non-System Controller or for automatic detection. Failing to do so may result in damage to the NI VXIpc-882 controller and/or the backplane.

When the NI VXIpc-882 controller is installed in Slot 0 of a VXI system it becomes the VXIbus System Controller. As the System Controller, the NI VXIpc-882 controller has VXIbus Data Transfer Arbiter circuitry that accepts bus requests on all four VXIbus request levels, prioritizes the requests, and grants the bus to the highest priority requester. As the VXIbus System Controller, the NI VXIpc-882 controller also drives the 16 MHz VXIbus system clock via an onboard 16 MHz oscillator. As required by the specification, when installed in Slot 0, the NI VXIpc-882 controller drives CLK10, a differential ECL output, to the VXIbus backplane. When the system is not installed in Slot 0 it will only receive the CLK10 signal.

MITE EEPROM

User/Factory Configuration

The EEPROM is divided into two halves—one half is factory configured and one half is user configurable. Use jumper W5 to control whether the NI VXIpc-882 controller boots off the factory-configured EEPROM settings or the user-modified settings. In its default setting, the NI VXIpc-882 controller boots off the user-configurable half.

This jumper is useful in the event that the user-configured half of the EEPROM becomes corrupted in such a way that the NI VXIpc-882 controller boots to an unusable state. By changing this jumper setting, you can boot to the factory configuration and get up and running again. Use the procedure as described in the How to Fix an Invalid

EEPROM Configuration section of this manual.

Power-On Self Configuration

The NI VXIpc-882 controller has an onboard EEPROM, which stores default register values for the VXI circuitry. These values are loaded when you power up the computer. The values read from the EEPROM program the PCI interface and the VXIbus registers so that the VXI interface is ready to respond to Resource Manager accesses within the required 5 seconds of SYSRST# deasserting.

You can disable this power-on self-configuration (POSC) circuit by changing switch W8. Although this makes the VXI circuitry unusable, it is sometimes helpful in debugging address and interrupt conflicts with add-in boards. In general, however, you should leave W8 in its factory-default setting. Figure 3-4 shows the possible configurations for W8.

How to Fix an Invalid EEPROM Configuration

Use MAX under Windows to edit the NI VXIpc-882 controller configuration. Some of these settings are stored in files that the NI-VXI software reads, while other settings are stored directly in the NI VXIpc-882 controller EEPROM.

Certain EEPROM configurations, including invalid configurations, can lock up your computer while it is booting. Generally, only the size and

Chapter 3 Configuration and Default Settings

location of the memory windows can cause the NI VXIpc-882 controller to lock up your system. For example, many PCI-based computers will not boot if a board in its system requests more memory space than the computer can allocate. If you encounter this situation, you should reduce the size of the NI VXIpc-882 controller user memory window. The EEPROM can become corrupted if the NI VXIpc-882 controller is shut down while it is updating the EEPROM.

If one of these situations occurs after you change the configuration, complete the following steps to reconfigure the NI VXIpc-882 controller.

1. Power off your computer.

Caution To protect both yourself and the mainframe from electrical hazards,

the mainframe should remain off until you finish changing the settings on the NI VXIpc-882 controller.

2. Change jumper W5 to the position shown in Figure 3-3b to restore the factory configuration.

3. Power on the computer. The computer should boot this time because the factory-default configuration is being used to initialize the NI VXIpc-882 controller.

4. Run your software configuration utility to re-adjust the NI VXIpc-882 controller configuration.

5. After saving the configuration, exit Windows and power off the computer.

6. Change jumper W5 to the default position, as shown in Figure 3-3a.

7. Power on the computer. If the computer does not boot with this configuration, you will need to repeat these steps, modifying your configuration until a final configuration is reached.

VXIbus CLK10 Routing

When the NI VXIpc-882 controller is installed in Slot 0 of your mainframe, it supplies the VXIbus CLK10 signal. Three different sources for CLK10 are available with the NI VXIpc-882:

• The internal 10 MHz ±50 ppm CLK10 oscillator. This is the default CLK10 source.

• The front panel CLK10 SMB. When configured as an input the front panel SMB allows an external source to be used as the source for the VXIbus CLK10 signal.

NI VXIpc-882 User Manual 3-8 ni.com

• The front panel TRIG/CLK PORT A(B). CLK10 can be routed into the NI VXIpc-882 from another NI VXIpc-882 through the TRIG/CLK PORT A(B) on the front panel. Onboard jumpers are used to set this configuration.

Front Panel SMB Direction Control

W2—SMB CLK10 Direction

This jumper allows you to configure the front panel SMB connector on the NI VXIpc-882 controller.

The default jumper position, shown in Figure 3-5a, IN, shuts off CLK10 to the front panel SMB connector. Use jumpers W4 and W3 to configure the front panel SMB as an input for CLK10. In non-Slot 0 operation the SMB cannot be configured as an input as only the Slot 0 controller is allowed to supply CLK10 to the VXI backplane.

Setting the W2 jumper to OUT, as shown in Figure 3-5b, routes the VXIbus CLK10 to the front panel SMB connector. In non-Slot 0 operation this jumper will also route the VXIbus CLK10 out of the front panel SMB connector.

Selecting the CLK10 Source

W3—External CLK10 Source Select

When W4—CLK10 Source Select is set to select an external CLK10 source, W3 is used to select between two external CLK10 sources.

• The default setting, shown in Figure 3-6a, SMB, selects the front panel SMB connector as the external CLK10 source. There is no need to set the direction of the SMB with jumper W2 as the controller will set the SMB as an input for you.

Chapter 3 Configuration and Default Settings

• Set the W3 jumper to Trigger Card, shown in Figure 3-6b, to select

the CLK10 source as the TRIG/CLK PORTA(B) on the NI VXIpc-882 front panel. When selecting the trigger card as the CLK10 input source be sure to set jumper W7 to set the direction of CLK10 through the TRIG/CLK PORT A(B).

BIOS Configuration

You can change the NI VXIpc-882 configuration settings in the BIOS setup. The BIOS is the low-level interface between the hardware and PC software that configures and tests your hardware when you boot the system. The BIOS setup program includes menus for configuring settings and enabling NI VXIpc-882 controller features.

Most users do not need to use the BIOS setup program, as the NI VXIpc-882 controller ships with default settings that work well for most configurations.

Caution Changing BIOS settings may lead to incorrect controller behavior and possibly

an unbootable controller. If this happens, follow the instructions for restoring default settings in the System CMOS section. In general, do not change a setting unless you are absolutely certain what it does.

Entering BIOS Setup

stored in a battery-backed real-time clock. Most operating systems also include a way to change this setting. Use <+> and <–> in conjunction with <Enter> and <Tab> to change these values.

• Require Keyboard to Boot—When Enabled, a missing or

malfunctioning keyboard causes the BIOS to halt with an error. When Disabled, the BIOS allows booting without a keyboard. If you are using a USB keyboard, you may attach it at any time during the powered up state. To use this controller in a “headless” mode, you must set this option to Disabled. The default value is Enabled.

Note Attaching a USB-to-PS/2 keyboard adapter may allow the system to boot even if no

PS/2 keyboard is attached.

• Num Lock—This setting indicates whether you turn on Num Lock at boot time. The default value is On.

• SATA Port 0/1—This item displays the SATA devices detected in the system. Normally, you do not need to modify this item. However, if a SATA device is not autodetected properly, you can specify it manually by pressing <Enter> on the item.

NI VXIpc-882 User Manual 3-14 ni.com

Chapter 3 Configuration and Default Settings

Caution Changing settings in this menu may result in an unstable or unbootable controller.

If this happens, follow the procedures outlined in the System CMOS section to restore BIOS settings to their factory defaults.

The Advanced setup menu includes the following settings:

• Reset Configuration Data—A portion of the EEPROM on the

controller is designated as the Extended System Configuration Data region (ESCD). The BIOS and Plug-and-Play operating systems use this table to store the Last Known Good configuration of system peripherals. If you experience resource conflicts or peripheral malfunction, set this setting to Yes to force the BIOS to recreate the ESCD on the next reboot. This is rarely necessary.

• Integrated Peripherals—Use this setting to bring up the Integrated Peripherals submenu. (Refer to the Integrated Peripherals Submenu section.)

• Quick Boot Mode—When you enable this option, certain lengthy BIOS tests that rarely fail are skipped to shorten controller boot time. The default is Enabled.

• Summary Screen—This setting controls the display of the summary screen shown after BIOS completes its initialization, but before booting takes place. You can disable this screen in the interest of shortening controller boot time. The default is Disabled.

• PXE Network Boot—This setting enables the option for booting from a network PXE server on the subnet. The default is Disabled.

Integrated Peripherals Submenu

Use this submenu to apply nondefault configurations to the front panel peripherals of an NI VXIpc-882 controller. Normally, you do not need to modify these settings, as the factory default settings provide the most compatible and optimal configuration possible.

• Serial Port A—This setting enables or disables COM1. You also can change this setting to Enabled and modify the base address and Interrupt Request Level (IRQ) of a port. The default is Auto, which places COM1 at 0x3F8 IRQ 4.

• Parallel Port—Use this setting to enable or disable LPT1. You also can change this setting to Enabled and modify the base address, IRQ level, and ISA Direct Memory Access (DMA) channel of the port. The default is Auto, which places LPT1 at 0x378, IRQ 7, using ISA DMA Channel 3 if necessary.

Chapter 3 Configuration and Default Settings

• Parallel Port Mode—The PC industry has created several different

modes of operation for this port over the years. Usually, the default setting works for all applications. However, if a parallel port device specifically requires a nondefault setting, you can change it here. The default is Bidirectional, for full IEEE 1284 capabilities.

• Legacy USB Support—Use this setting to use a USB keyboard and

mouse as if they were standard PS/2-style peripherals. You must enable this setting to use these devices in operating systems with no USB support and to boot from a USB floppy or CD-ROM. The BIOS setup screen always works with USB keyboards regardless of this setting. The default is Enabled.

• SATA Mode—This setting determines whether the SATA controller operates in Enhanced or Compatible mode. Enhanced mode provides the advanced features of a SATA controller, while Compatible mode provides legacy backwards compatibility with standard ATA for operating systems that do not natively support SATA. The default setting is Enhanced.

• AHCI Configuration—This setting determines whether AHCI mode is Enabled or Disabled for the SATA port. Because some operating systems do not support AHCI mode, you can use this setting to disable AHCI mode so that non-compatible OSes function correctly. The default setting is Enabled.

• Multi-Core Processing—This setting determines whether or not the second core processor on the Intel The default setting is Enabled.

• Monitor DDC—This setting determines how the monitor DDC is routed. Use this setting to select whether or not the DDC is routed for an Analog monitor or a DVI monitor. In order to use a DVI monitor, this setting must be set to DVI. An analog monitor, however, will function with this option set to either Analog or DVI. The DDC communication path is only enabled when set to Analog for an analog monitor, so certain advanced features of your analog monitor may only be enabled when routing DDC to Analog. The default setting is DVI.

• Force IGD Primary—This setting determines how the BIOS prioritizes video controllers when external video cards are present in the system. During POST, only one device can act as the video display device. When set to Enabled, the BIOS allows the integrated graphics device to remain the video display device. When set to Disabled, the BIOS allows an external graphics card, if present, to act as the default video display device. Note that even when set to Disabled, the integrated graphics device still acts as the video display device if it is the only one available in the system. The default setting is Disabled.

Core™ 2 Duo T7400 is enabled.

4. Wait one second. Move the jumper back to pins 1–2.

5. Reinstall the controller in the chassis.

Caution Do not leave the jumper on pins 2–3. Doing so decreases battery life. In addition,

leaving the jumper on the pins prevents the controller from booting.

Chapter 3 Configuration and Default Settings

Default MAX Settings

The General tab for the VXIpc MAX hardware configuration contains two options for quickly configuring your VXIpc controller. You can use the Quick Configuration table to select from a few commonly used configurations. The default setting lists Current Board Configuration, which means the current hardware configuration is set according to the last user modifications made. Table 3-7 lists the configurations you can select.

Note Whenever you open the hardware configuration, MAX reports that the VXIpc is

in Current Board Configuration. This means that if you select one of the common configurations such as LA 5 Message Based and save the configuration, the next time you open MAX, it will not report that the Current Board Configuration is LA 5 Message Based as you might expect. If you have used a common configuration setting, closed and reopened MAX, and want to verify the current VXIpc configuration, you must check each tab for the current controller configuration.

In MAX, you can load a VXIpc configuration from a file or save the current configuration for future use. You may execute this option by selecting one of the options in the General tab in the MAX hardware configuration.

Front Panel SMB ExtClk Setup

The NI VXIpc-882 computers have an SMB connector on the front panel for an external clock. Onboard programmable logic can configure the NI VXIpc-882 to drive its 10 MHz VXI CLK10 signal to this connector as an output or to use this connector as an input for the 10 MHz VXI CLK10 signal. In this fashion, you can configure multiple mainframes to operate off a single 10 MHz system clock. Refer to the VXIbus CLK10 Routing section for information on properly configuring the hardware to use the CLK10 routing feature of the NI VXIpc-882.

Front Panel SMB TRGIN/TRGOUT

The NI VXIpc-882 gives programmers full hardware and software control over the VXI trigger lines. The NI VXIpc-882 has two SMB trigger I/O connectors on its front panel for routing any of the TTL trigger lines between the backplane and external devices. The VXI trigger interface is based on the advanced MANTIS ASIC developed by National Instruments. The MANTIS provides the complete NI VXIpc-882 VXI interface to the outer rows of the P2 backplane connector in a single chip. The NI VXIpc-882 can respond to all VXI-defined protocols on all P2 TTL and ECL trigger lines at the same time. The MANTIS features an internal cross-matrix switching system for routing between lines as well as to and from the front panel and onboard clocks. An internal counter gives sophisticated counting of events and interrupting on trigger edges and pulses, as well as generating pulse trains, variable length pulses, and pulse stretching.

Chapter 3 Configuration and Default Settings

You have the option to terminate the external trigger input SMB with 50 Ω to ground to match the driving source, if necessary. Use MAX to set this option.

Developing Your Application

This chapter discusses the software utilities you can use to start developing applications that use NI-VXI.

After installing the NI-VXI software, you can begin developing your VXI/VME application. Be sure to check the release notes for the latest application development notes and changes.

NI-VXI, NI-VISA, and Related Terms

Before you develop your application, it is important to understand the difference between NI-VXI, NI-VISA, and similar terms:

• NI-VXI is the software package that ships with National Instruments VXI and VME controllers. NI-VXI includes Measurement & Automation Explorer (MAX), NI-VISA, NI Spy, Resource Manager (Resman), VXI device drivers, and other utilities for configuring and controlling your VXI or VME system.

• NI-VISA is the native API for communicating with VXI/VME devices. NI-VISA is the National Instruments implementation of the VISA I/O standard, which is a common interface to many types of instruments (such as VXI, GPIB, PXI, Serial, TCP/IP, and so on). NI-VXI is optimized for use through NI-VISA, and we recommend using NI-VISA to develop all new VXI/VME applications.

• The NI-VXI API is an optional development environment that is not part of the default NI-VXI installation. The NI-VXI API was developed before NI-VISA; while NI-VXI still supports the NI-VXI API, we recommend using NI-VISA for all new VXI/VME applications. If you must develop an application using the older NI-VXI API, run the NI-VXI installer and select the appropriate option in the custom installation screen. Be sure to review the NI-VXI API

Notes section later in this chapter.

• The NI-VXI compatibility layer allows older programs that use the NI-VXI API to communicate with VXI devices through VISA. Using this compatibility layer, older programs can run in NI-VXI 3.0 or later without being rewritten to use the VISA interface. This layer installs with NI-VXI by default. It should be completely transparent and

Chapter 4 Developing Your Application

provide a high level of performance; however, there may be some slight changes in behavior for certain applications.

Your software features several system development utilities including MAX, Resman, NI Spy, VISA Interactive Control (VISAIC), and VXI Interactive Control (VIC, optional). You can also access help and a variety of examples to learn how to use NI-VXI for certain tasks.

Each component assists you with one of four development steps: configuration, device interaction, programming, and debugging.

You can access the utilities, help files, and release notes through the Windows Start menu by opening the National Instruments»VXI or National Instruments»VISA program groups.

Configuration

The configuration utilities in your software kit are Resman and MAX.

Resman performs VXI Resource Manager functions as described in the VXIbus specification. Resman configures all devices on the VXI backplane for operation and allocates memory for devices that request it. Resman does not require you to specify any settings; it automatically performs the VXI resource management whenever you run it.

Note Power cycling resets all devices, so you must run Resman to reconfigure your

system every time you cycle the power on the chassis.

MAX presents a graphical display of your entire test and measurement system to help you configure various components. When you launch MAX, you see all your devices (including VXI) on the screen. You can view the properties (such as logical address, address space, and so on) of each device by clicking the device in the configuration tree. To see additional configuration options for a given device, right-click the device in the configuration tree. When you access the properties of most National Instruments devices by right-clicking, you can configure the hardware settings by selecting Hardware Configuration.

MAX and Resman are designed to work together. You can run Resman through MAX by either clicking the Run VXI Resource Manager button in the toolbar or right-clicking a specific VXI system on which to run Resman (refer to Figure 4-1). You can also select Tools»NI-VXI»VXI

Resource Manager to run Resman on all VXI systems. From the VXI Options dialog in the Tools»NI-VXI menu, you can also use MAX to

NI VXIpc-882 User Manual 4-2 ni.com

Chapter 4 Developing Your Application

configure Resman to run on all VXI systems automatically when the computer boots. Resman reports to MAX all errors it finds in your system; when you view your VXI system in MAX, you can easily spot any errors that Resman found while configuring the system.

Figure 4-1. Right-Click a VXI System in MAX to Run Resman on that System

After Resman detects and configures all your VXI/VME devices, you can use MAX to view specific information about each device in your system. The default MAX view of a VXI system shows the General tab window, which contains a summary of key information about each device, including its device name, logical address, model name, and other data.

For more information about MAX, refer to its help by selecting the Help» Help Topics menu.

Device Interaction

You can interact with your VXI/VME devices using the VISA Interactive Control (VISAIC) utility. VISAIC allows you to control your VXI/VME devices without using a conventional programming language, LabVIEW, or Measurement Studio. You can also control your devices in MAX by right-clicking a device name and selecting Open VISA Session.

Chapter 4 Developing Your Application

Note You can also use VXI Interactive Control Program (VIC) to control your VXI/VME

devices and develop and debug VXI application programs. VIC is not included in the default NI-VXI installation; to install it, select NI-VXI API Development from the custom installation screen in the installer.

You can launch VISAIC (or VIC) from the Tools menu in MAX or from the VISA or VXI subgroups in Start»Programs»National Instruments.

Try the following in VISAIC: In the tree view, navigate using your mouse to the VISA resource for your controller—probably VXI1::0::INSTR, representing the VXI system 1, logical address 0 instrument resource (refer to Figure 4-2).

Figure 4-2. Select Your Controller in VISAIC

Open the selected resource and navigate to the Register I/O tab. In this tab, you can read registers on your device, such as the VXI device configuration registers. Execute the viIn operation (called In in LabVIEW compatibility mode) with the default parameters. The Data Value field shows the I/O operation result, such as function status, such as

NI VXIpc-882 User Manual 4-4 ni.com

0x9ff6. The Return Value field shows the

0 for VI_SUCCESS (see Figure 4-3).

Chapter 4 Developing Your Application

Figure 4-3. Successful viIn Access in the VISAIC Register I/O Tab

(This Dialog Box May Look Slightly Different for LabVIEW Users)

If the data value ends in ff6, you have successfully read the National Instruments manufacturer ID from your VXI/VME controller’s ID register.

You may now want to read the configuration registers from other VXI devices in your system by opening the devices in VISAIC. Try reading a register from each device listed in the MAX view of your VXI system. This way, you can verify that your VXI controller can access each device in your VXI system successfully.

You can also access VXI and VME devices configured in A16, A24, or A32 space by opening the VXI MEMACC resource, which is VISA’s representation of VXI memory. For more information about VISAIC operations and commands, refer to the help in the Help menu and the context-sensitive help (such as What’s This?) available by right-clicking in any panel.

Programming for VXI

NI-VISA and the NI-VXI API are the two National Instruments programming interfaces for accessing your VXI/VME instruments. With NI-VXI 3.0 or later, NI-VISA is the native API for communicating with a VXI or VME system, and we recommend using it for all new applications.

Chapter 4 Developing Your Application

Older programs that use the NI-VXI API now use the NI-VXI-to-NI-VISA compatibility layer to communicate with the VXI devices. Using this layer, older programs can run in NI-VXI 3.0 or later without being rewritten to use the VISA interface. For more information about programming with NI-VISA, refer to the NI-VISA Help, which you can find at

ni.com/support.

Note The NI-VXI API development environment is not installed by default as part of the

NI-VXI installation. If you must develop an application using the older NI-VXI API, run the NI-VXI installer and select the appropriate option in the custom installation screen. Be sure to review the NI-VXI API Notes section later in this chapter.

NI-VISA is the National Instruments implementation of the VISA API as the VXIplug&play standard defines. It provides a common interface to many types of instruments (such as VXI, GPIB, PXI, Serial, TCP/IP, and so on) and therefore is especially useful in situations where you are using multiple types of instruments.

Both NI-VISA and the NI-VXI API include functions for register-level access to VXI instruments and messaging capability to message-based devices. You can also use either interface to service asynchronous events such as triggers, signals, and interrupts, and also assert them. Compatibility with the NI-VXI API is included for legacy applications only—we recommend that you write all new VXI/VME applications in VISA.

The best way to learn NI-VISA programming is by reviewing the example programs your software includes. The examples directory contains working VISA programs that illustrate many different types of applications. You can find these examples in the

NIvisa\Examples

directory.

VXIpnp\WinNT\

If you are just getting started, you should learn how to access registers with high-level calls and send messages with word-serial functions. The NI-VISA examples for these tasks are

HighReg.c and RdWrt.c. Refer

to the other examples as you try more advanced techniques. Consult the NI-VISA Help for additional information on these topics.

Optimizing Large VXIbus Transfers

For best performance, keep the following in mind when using viMove() or

VXImove():

• Make sure your buffers are 32-bit aligned.

• Transfer 32-bit data whenever possible.

• Use VXI block access privileges to significantly improve performance to devices that are capable of accepting block transfers.

• To optimize move performance on virtual memory systems, lock the user buffer in memory yourself so the move operation does not need to lock the buffer.

• To optimize move performance on paged memory systems, use a contiguous buffer so the move operation does not need to build a scatter-gather list for the user buffer.

RdWrt.c VXIws.c

HighReg.c VXIhigh.c

LowReg.c VXIlow.c

Note viMemAlloc() or VXImemAlloc() returns 32-bit aligned, page-locked,

contiguous buffers which work efficiently with the move operations.

NI-VXI API Notes

The following notes apply only if you are using the NI-VXI API. We recommend that all new VXI/VME applications use the NI-VISA API, but you can still develop with the older NI-VXI API for compatibility with legacy code.

Compiler Symbols

You may need to define certain compiler symbols so that the NI-VXI library can work properly with your program. The required symbol indicates your operating system platform; for example, the application as a Windows Vista/XP/2000/Me/9x/NT application.

Note LabWindows/CVI automatically defines the correct symbol. You do not need to

VXINT designates

The additional symbol the resulting application is binary compatible with other National Instruments VXI controllers using the same operating system. This symbol may cause a slight performance degradation when you use low-level VXIbus access functions.

You can define these symbols using code or using the appropriate option in your compiler (typically either or

/D). If you use #define statements, they must appear in your code

before the line that includes the NI-VXI API header

BINARY_COMPATIBLE is optional. It ensures that

Compatibility Layer Options

Although NI-VXI supports multiple VXI controllers through NI-VISA, the NI-VXI API supports only a single controller. To specify which controller the emulation layer should use, run MAX. Select Tools»NI-VXI»VXI Options. Select the VXI system that will support the emulation layer.

In NI-VXI 3.0 or later, when you enable for triggers or interrupts, only the local controller is enabled. In the NI-VXI API functions for enabling

NI VXIpc-882 User Manual 4-8 ni.com

Chapter 4 Developing Your Application

triggers and interrupts, the controller parameter is ignored. If you need to enable a remote controller for triggers, use the MAX frame resource to map the trigger back to the local controller.

The interrupt and trigger routing in the NI-VXI 3.0 or later low-level drivers is somewhat different from the default routing in previous versions of NI-VXI. Therefore, the compatibility layer may behave differently than the original NI-VXI API with regard to these settings. In particular, if you are receiving triggers on an external controller, you may need to modify the trigger configuration on your extender module using MAX. In general, interrupts are routed automatically based on the interrupt configuration the resource manager detects. Whether the changed routing behavior affects your program is application dependent.

Because VISA is an instrument-centric API, certain functions from the more controller-centric NI-VXI API do not match perfectly with a VISA counterpart. When an application enables an event with the NI-VXI API compatibility layer, each logical address is enabled for that event separately. For example, if the application enables an interrupt level, VISA will enable the interrupt on each logical address, one at a time, until all the devices are enabled. This means that some interrupts could be lost from devices with higher numbered logical addresses. MAX provides an option for users to pick which logical address is enabled first. Select Tools»NI-VXI»VXI Options. Set Prioritized Signal LA to the logical address of the device that generates the events. This prevents possible loss of events from that device.

Debugging

NI Spy and VISAIC are useful utilities for identifying the causes of problems in your application.

NI Spy tracks the calls your application makes to National Instruments programming interfaces, including NI-VISA, NI-VXI, and NI-488. NI Spy highlights functions that return errors, so during development you can quickly spot which functions failed during a program’s execution. NI Spy can log the calls your program makes to these drivers so you can check them for errors at your convenience, or use the NI Spy log as a reference when discussing the problem with National Instruments technical support. Figure 4-4 shows an example of a normal error returned from a call to

viMemAlloc when no memory has been shared.

Chapter 4 Developing Your Application

VISAIC, discussed in the Device Interaction section of this chapter, is an excellent platform for quickly testing instruments and learning how to communicate with them. Refer to the NI-VISA Help for more information about using VISAIC.

• USB DVD/CD-ROM—Windows XP supports USB mass storage

devices. With most USB DVD/CD-ROM drives, once you plug the drive into the USB port, you should be able to access the drive through a drive letter.

• Mapped network drive—You can use the Ethernet to connect to

another computer. If you share the CD-ROM drive on the other computer, you can map the shared CD-ROM drive to a drive letter on the NI VXIpc-882.

How do I flash a new BIOS?

Follow the instructions for upgrading your BIOS by executing a search for VXI BIOS at

ni.com/support.

Where do I get the latest software and peripheral drivers?

Boot Options

Note There are some limitations when booting from a USB device. Windows does not

support booting from USB devices. Windows XP can be installed from a USB DVD/CD-ROM, but earlier versions of Windows cannot. The NI VXIpc-882 BIOS configures the USB devices so they will work in a DOS environment.

You can download the latest drivers from

vxisupp.htm

. For instructions on installing the latest peripheral drivers,

execute a search for VXI Peripherals at

ni.com/support/

ni.com/support.

What devices can I boot from?

The NI VXIpc-882 can boot from the following devices:

• The internal SATA hard drive.

• An external USB mass storage device such as a USB hard drive or CD-ROM.

• An external USB floppy drive.

• A network PXE server on the same subnet.

Chapter 6 Common Questions and Troubleshooting

How do I configure the controller to boot from these devices?

There are two methods:

• Enter Setup and select the Boot menu. You will see a list of all

bootable devices, ordered by device type. You can set the boot order using <+> and <–>. Set the order by device type and set the order for the devices listed within the device type.

• To boot from a different device without permanently changing the boot order, press <F10> during POST. After the BIOS completes the POST and just before the controller boots the OS, the Boot menu is displayed. You can select the device type you want to boot from.

Hard Drive Recovery

The NI VXIpc-882 controller includes two methods of restoring the original factory condition of your hard drive. Hard drive-based recovery stores a factory backup on a separate portion of your hard drive allowing you to restore your controller without additional media. The NI VXIpc-882 controller also ships with an OS Recovery CD that allows you to reinstall your operating system onto your hard drive through an external DVD/CD-ROM. For more information on these tools, refer to the documentation on your hard drive in the or KnowledgeBase 2ZKC02OK at

c:\Images\Recovery directory

ni.com/support.

Note Your system hot key is <F4>. To access the hard drive-based recovery tool, press and

hold <F4> when video first appears during the boot process.

If you need to recover your factory-installed operating system from a DVD/CD, you can use the included OS re-installation CD with an external DVD/CD-ROM drive such as a USB DVD/CD-ROM drive. Boot the controller using the OS re-installation CD to recover the OS. You also may need to reinstall other software after using the CD to recover the OS.

Note Recovering the OS erases the contents of your hard disk. Back up any files you want

to keep.

Installing an OS

The NI VXIpc-882 controller includes a pre-installed OS. In some cases, you may want to install a different OS. When doing so, consider the following guidelines.

NI VXIpc-882 User Manual 6-4 ni.com

Installing from a DVD/CD-ROM

The NI VXIpc-882 controller supports the installation of Windows XP from a USB DVD/CD-ROM. However, many other operating systems do not support installation from a USB DVD/CD-ROM. For example, Windows 2000 aborts during the install process because it does not have drivers for the DVD/CD-ROM device.

With DOS drivers, you can install Windows 9x operating systems. However, only a few USB DVD/CD-ROM drives have DOS drivers.

As an alternative to a USB DVD/CD-ROM drive, you can use an external SCSI DVD/CD-ROM with a VXI-SCSI adapter.

Chapter 6 Common Questions and Troubleshooting

My controller boots fine until I get to Windows, at which point I cannot read the screen. This may include garbled output, white screen, black screen, or an out of sync message from the monitor.

This problem usually results from having the video card output set past the limits of the monitor. You will need to boot Windows in Safe Mode. To do this, reboot the controller. As Windows begins to boot, hold down <F8>. You should now be able to reset the video driver to lower settings. Try setting the resolution to 640 × 480 and the refresh rate to 60 Hz. After you reboot, you can raise these values again, using the test option in Windows. These settings are accessible through the Advanced tab of the Display item in the Control Panel. Alternately, you can try a different monitor, preferably a newer and larger one.

My CMOS is corrupted. How do I set it back to default?

1. Enter the BIOS setup program as described in the BIOS Configuration section of Chapter 3, Configuration and Default Settings.

2. Press <F9> to load BIOS defaults.

3. Answer Y (Yes) to the verification prompt.

4. Select Save and Exit Setup.

I can’t change the display on the controller from 640 × 480 to 800 × 600. What’s wrong?

Using The Trigger Ports On The NI VXIpc-882

The NI VXIpc-882 allows you to extend the 8 TTL backplane triggers and CLK10 between chassis through convenient front panel connectors. Each trigger and the CLK are independently configurable as either inputs or outputs of the frame. The trigger bus is connected in a daisy chain topology and can support up to six (6) devices with a total of 19 m of cables.

Cautions The trigger bus uses the MXI-Express x4 cables, however these are not

MXI-Express x4 ports. Do not connect the trigger ports to a MXI-Express x4 or PCI Express x4 device.

The trigger bus may be able to support more devices and/or greater cable lengths, but these configurations have not been validated by National Instruments and are not currently supported.

Connecting the Trigger Port Cables

When connecting the cables between two devices on the trigger bus, always ensure you connect TRIG/CLK PORT A of one device to TRIG/CLK PORT B of the second device, or TRIG/CLK PORT B of one device to TRIG/CLK PORT A of the second device, as shown in Figure B-1. The front panel LED will blink red if the cables are not connected correctly. The LED will be lit steady state green if they are connected properly.

Note Trigger bus cables may be removed and inserted while power is on.

Appendix B Using The Trigger Ports On The NI VXIpc-882

1 TRIG/CLK PORT A 2 TRIG/CLK PORT B

Software Configuration

Triggers are mapped into and out of your NI VXIpc-882 though software using the following steps.

1. Open MAX.

2. Find your device under Devices and Interfaces.

3. Right click on your device and select Properties.

4. Click on the Signal Mappings Tab.

5. From each TTL Trigger select Into the Frame, Out of the Frame, or None.

6. Click OK and re-run the VXI Resource Manager (Resman) for the changes to take effect.

Note Do not map the same trigger out of the frame on more than one device on the trigger

bus. This will cause the bus to be driven by more than one device. Protection circuitry prevents this from causing physical damage, however your setup will not function properly.
