Description and Features

The NI VXI-8360T/LT controller is a C-size, VXIbus, Slot 0-capable device that can reside in any C-size or D-size VXI mainframe.

Note

D-size VXI mainframes have connections for a P3 connector. The NI VXI-8360T/LT controller, however, does not have this connector and cannot provide the necessary control for VXI devices that need P3 support.

The NI VXI-8360T/LT controller links a PCI Express-based host computer to the VXIbus using the National Instruments MXI-Express x1 interface. The MXI-Express x1 link enables your computer to perform as though it were plugged directly into the VXI backplane, giving it the capabilities of an embedded computer.

With MXI-Express x1, you can do the following:

• Control a VXI backplane with a PCI Express or ExpressCard-based PC or laptop/mobile host adapter.

• Physically separate the measurement or automation system from a host PC or laptop.

• Combine VXI, PCI Express, CompactPCI, CompactPCI Express, PXI, PXI Express, and CompactRIO devices into the same system.

Several different MXI-Express x1 interfaces are compatible with the NI VXI-8360T/LT controller. Refer to the Set Up Your MXI-Express x1 System Guide included in this kit for information about connectivity support.

The NI VXI-8360T incorporates functionality allowing the extension of the 8 TTL backplane triggers and CLK10 between multiple chassis through convenient front panel connectors. Refer to Appendix C, Using the Trigger

Ports on the NI VXI-8360T, for more information about using the

The NI VXI-8360T/LT is, by factory default, hardware configured to automatically detect if it is in Slot 0, and will supply a CLK10 sourced from an onboard oscillator. Refer to Appendix B, Advanced Hardware

Configuration Settings, for additional hardware configuration options.

MXI-Express x1 Functional Overview

The NI VXI-8360T/LT controllers enable control of a VXI mainframe with a host computer using MXI-Express x1 technology.

MXI-Express x1 is based on PCI Express technology. A MXI-Express x1 kit may use a combination of PCI Express switches or PCI Express-to-PCI bridges to enable control of a VXI chassis from a PC with an available PCI Express or ExpressCard slot.

The link between the PC and the chassis is a x1 cabled MXI-Express link. This link is a dual-simplex communication channel comprised of a low-voltage, differentially driven signal pair. The link can transmit at a rate of 2.5 Gbps in each direction simultaneously. This port is not compatible with the cabled PCI Express specification developed by the PCI-SIG.

The BIOS of some host machines may not support the extension of the PCI-Express fabric or PCI bus. Since this is the primary function of MXI-Express x1 products, those systems may not boot or function correctly. To address this issue, certain MXI-Express x1 products have additional functionality intended to hide all PCI or PCI-Express resources that are connected to the host machine allowing NI MXI-Express BIOS Compatibility Software to handle the enumeration process of these resources.

In the cases where this software is required, there may be a dip switch on the MXI-Express x1 host adapter that needs to be toggled as instructed by the documentation for the software.

Larger MXI-Express x1 Systems

By leveraging the PCI Express technology used in MXI-Express x1 products, you can connect more than a single chassis to a host controller.

The NI PCIe-8362, for example, has two MXI-Express x1 ports. This allows for connecting two targets simultaneously, also known as a star configuration or star topology. Also, if multiple PCI or PCI Express slots are available in the host PC, additional chassis can be connected by installing additional NI MXI-Express x1 host boards to achieve the same star topology.

You can also daisy-chain from a PXI or PXI Express chassis that is already controlled by an embedded controller, host PC, or laptop to a VXI mainframe using MXI-Express x1 products.

Figure 1-4. Example MXI-Express x1 System Expansion Topologies

Note The NI VXI-8360T/LT controller cannot be used to daisy-chain the MXI-Express

x1 link from one VXI mainframe to another VXI mainframe.

Chapter 2 Installation and Configuration

restore them to the TBL subdirectory of your NI-VXI directory before running MAX.

Note If you save and restore the TBL files from an older version of NI-VXI, the software

will use TBL files that do not have the latest updates from National Instruments and may not include recent hardware releases. If you added additional manufacturer or model names to your TBL files, we recommend merging those changes with the latest updates included with this version of NI-VXI, so that all your devices are properly identified.

For more information about the NI-VXI API, refer to Chapter 3,

Developing Your Application.

Hardware Installation and Configuration

Prior to installation of the NI VXI-8360T/LT controller, determine if any onboard jumper settings need to be changed. The NI VXI-8360T/LT controllers’ default configuration of onboard jumpers should be acceptable for most systems. Refer to Appendix B, Default Jumper Settings, only if your system uses the front-panel CLK10 and trigger SMB connectors.

Caution To guard against electrostatic discharge, touch the antistatic plastic packages to a

metal part of your computer or chassis before removing the boards from their packages. Your computer or chassis should be plugged in but powered off.

Caution The protection provided by the NI VXI-8360T/LT device can be impaired if it is

used in a manner not described in this document.

Installing Your NI VXI-8360T/LT Controller

4. Firmly press the NI VXI-8360T/LT controller into the mating connectors to ensure the module is fully inserted and seated in the connector.

5. Tighten the two ejector handle screws.

Chapter 2 Installation and Configuration

6. Verify that any other VXI devices with system controller capability that are in the same chassis are not configured as system controller.

7. Ensure that no other VXI devices in your system are manually configured for the same logical address as your controller.

Note Although the NI VXI-8360T/LT controllers are typically installed in Slot 0 of the

VXI chassis, they may operate in other slots of the chassis. If you choose to install the controller in a slot other than Slot 0, the automatic detection circuitry on the controller will detect the slot and configure the controller appropriately, as long as the J2 jumper is set to Auto-detect.

Caution Having more than one device configured as system controller can damage the

VXI system. For VXI systems that include VME devices, ensure that the VME devices are not configured in the upper 16 KB (starting from 0xC000) of the A16 address space. This region is reserved for VXI device configuration registers, which are used for initializing, configuring, and interacting with VXI devices. The NI VXI-8360T/LT controller also uses this region for this purpose.

Developing Your Application

This chapter discusses the software utilities you can use to start developing applications that use NI-VXI. Be sure to check the release notes for the latest application development notes and changes.

Your software features several system development utilities including MAX, Resman, NI I/O Trace, VISA Interactive Control (VISAIC), and optionally VXI Interactive Control (VIC). You can also access online 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.

National Instruments Application Software

In addition to the NI-VISA/NI-VXI software, you can use the National Instruments LabVIEW, Measurement Studio, and LabWindows application programs and instrument drivers to ease your programming task. These standardized programs match the modular virtual instrument capability of VXI and can reduce your VXI/VME software development time. These programs are fully VXIplug&play compliant and feature extensive libraries of VXI instrument drivers written to take full advantage of direct VXI control. LabVIEW, Measurement Studio, and LabWindows/CVI include 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.

™

/CVI™

Chapter 3 Developing Your Application

Measurement Studio allows you to choose from standard environments such as Microsoft Visual Basic, Visual C++, and Visual Studio .NET to create your application, using tools specific for each language. With Measurement Studio, you can write programs quickly and easily and modify them as your needs change.

LabWindows/CVI is an interactive ANSI C programming environment designed for building virtual instrument applications. LabWindows/CVI delivers a drag-and-drop editor for building user interfaces, a complete ANSI C environment for building your test program logic, and a collection of automated code generation tools, as well as utilities for building automated test systems, monitoring applications, or laboratory experiments.

To use any of these application programs, install them before installing the NI-VISA/NI-VXI software. LabVIEW, Measurement Studio, and LabWindows/CVI integrate the VXI and VISA libraries required to support your NI VXI-8360T/LT controller. 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.

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/NI-VISA CD is the software package that ships with National Instruments VXI and VME controllers. This software CD includes Measurement & Automation Explorer (MAX), NI-VISA, NI I/O Trace, 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 NI recommends using NI-VISA to develop all new VXI/VME applications.

•The NI-VXI API is an optional development environment that was developed before NI-VISA. Although NI-VXI still supports the NI-VXI API, NI recommends using NI-VISA for all new VXI/VME applications. Refer to the NI-VXI API Notes section for more information regarding the NI-VXI API.

VXI-MXI-Express Series User Manual 3-2 ni.com

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

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 NI recommends using it for all new applications. Older programs that use the NI-VXI API now use the NI-VXI-to-NI-VISA compatibility layer to communicate with the VXI devices.

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— NI recommends that you write all new VXI/VME applications in VISA.

Chapter 3 Developing Your Application

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 Windows Start menu under Programs» National Instruments»VISA»Examples.

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

Table 3-1 summarizes the topics the example programs address. All NI-VISA files are found through the Windows Start menu under Programs»National Instruments»VISA»Examples, in the subdirectories listed below.

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 can accept block transfers, and likewise use D64 access privileges for devices that can accept the VME64 64-bit data transfer protocol.

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

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

continuous buffers that work efficiently with the move operations.

NI-VXI API Notes

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

define

VXINT when using LabWindows/CVI.

Chapter 3 Developing Your Application

The following notes apply only if you are using the NI-VXI API. National Instruments recommends 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, VXINT designates the application as a Windows 2000/NT/XP/Me/98 application.

The additional symbol that 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 on some controllers.

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

#define statements in your source

–D

nivxi.h.

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 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. Refer to the NI-VISA Help for additional information.

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

Chapter 3 Developing Your Application

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. Consult the manual for your extender module for details. 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.

Device Interaction and Debugging Tools

NI I/O Trace and VISAIC are useful utilities for identifying the causes of problems in your application, and are installed by default with your NI-VXI installation.

NI I/O Trace

NI I/O Trace tracks the calls your application makes to National Instruments drivers, including NI-VISA, NI-VXI, and NI-488. NI I/O Trace highlights functions that return errors, so during development you can quickly spot which functions failed during a program’s execution. NI I/O Trace can log the calls your program makes to these drivers so you can check them for errors at your convenience, or use the NI I/O Trace log as a reference when discussing the problem with National Instruments technical support. Figure 3-1 shows an example of an error returned from a call to

viMemAllocEx

VXI-MXI-Express Series User Manual 3-6 ni.com

Chapter 3 Developing Your Application

Figure 3-1. NI I/O Trace

VISA Interactive Control (VISAIC)

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 LabVIEW, Measurement Studio, LabWindows/CVI, or another programming language. You can also control your devices in MAX by right-clicking a device name and selecting Open VISA Session.

Try the following in VISAIC: In the tree view, navigate using your mouse to the VISA resource for your controller—probably VXI0::0::INSTR, representing the VXI system 0, logical address 0 instrument resource, as shown in Figure 3-2.

Chapter 3 Developing Your Application

Figure 3-2. Select Your Controller in VISAIC

Open the selected resource and navigate to Input/Output and select the In tab. In this tab, you can read registers on your device, such as the VXI

device configuration registers. Execute the In operation with Width set to 16-bits and other parameters set to default values. The In Value field shows the I/O operation result, such as function status, such as

No Error for VI_SUCCESS, as shown in

0x8ff6. The Return Data field shows the

Chapter 3 Developing Your Application

Figure 3-3. Successful In Access in the VISAIC Input/Output Tab

(This Window 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 online help in the Help menu and the context-sensitive help (such as What’s This?), available by clicking Help and mousing over any panel.

VXI Interactive Control (VIC)

You can also use VXI Interactive Control Program (VIC) to control your VXI/VME devices and develop and debug VXI application programs. You can launch VISAIC (or VIC) from the Tools menu in MAX or from the VISA or VXI subgroups in Start»Programs»National Instruments.

Slot 0 Detection

The NI VXI-8360T/LT 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 VXI-8360T/LT controller can be installed in any VXIbus slot.

The NI VXI-8360T/LT controller can be manually configured for either System Controller or Non-System Controller operation. Use the three position jumper J2 as shown in Figure B-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 VXI-8360T/LT controller and/or the backplane.

When the NI VXI-8360T/LT controller is installed in Slot 0 of a VXI system it becomes the VXIbus System Controller. As the System Controller the NI VXI-8360T/LT 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 VXI-8360T/LT 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 VXI-8360T/LT 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.

Appendix B Advanced Hardware Configuration Settings

VXIbus CLK10 Routing

When the NI VXI-8360T/LT 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 VXI-8360T/LT controller:

• The internal 10 MHz ±100 ppm CLK10 oscillator. This is the default CLK10 source.

• The front panel EXT CLK SMB connector. 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 VXI-8360T Only) The front panel TRIG/CLK PORT A(B). CLK10

• can be routed into the NI VXI-8360T from another NI VXI-8360T through the TRIG/CLK PORT A(B) on the front panel. Onboard jumpers are used to set this configuration.

Power-On Self Configuration

The NI VXI-8360T/LT 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 B-5 shows the possible configurations for W8.

VXI-MXI-Express Series User Manual B-8 ni.com

Figure B-5. Power-on Self Configuration Status

Using the Trigger Ports on the NI VXI-8360T

The NI VXI-8360T allows you to extend the 8 VXI backplane triggers and CLK10 through convenient front panel connectors. Each trigger and the CLK are independently configurable as either inputs to the frame or outputs from the frame. The wired VXI backplane trigger and CLK10 bus is connected in a daisy chain topology and can support up to 6 devices with a total of 19 m of cables.

Cautions The wired VXI backplane trigger and CLK10 bus uses MXI-Express x4 cables

and connectors, 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 wired VXI backplane trigger and CLK10 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 C-1.

If the cables are not connected correctly, the Cable Status LED will blink red, and the trigger drivers in that system will be disabled.

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

End of bus termination is also required for proper operation. The VXI-8360T automatically detects its position on the wired VXI backplane trigger and CLK10 bus and it will enable its termination if it detects it is at the end of the bus

Appendix C Using the Trigger Ports on the NI VXI-8360T

Configuring the Wired Trigger and Clock Bus

Each of the 8 physical trigger channels is independently configurable and designed to be used in a point-to-multipoint topology where one device acts as the trigger driver and the remaining devices are listeners.

To map a trigger from the VXI backplane to multiple chassis, configure the trigger to be mapped as Out of the Frame in MAX. This configures the trigger as a driver. The remaining devices on the wired VXI backplane trigger and CLK10 bus need to be configured as listeners by configuring their respective triggers as In to the Frame.

To ma p CLK 10 Out of the Frame set jumper W7 to connect pins 1-2. To map CLK10 In to the Frame set jumper W7 to connect pins 2-3. Refer to Appendix B, Advanced Hardware Configuration Settings, for more information about setting the hardware jumper.

Using the Trigger Ports on the NI VXI-8360LT

The NI VXI-8360LT allows you to extend the 8 TTL backplane triggers over a wired VXI backplane trigger bus through convenient front panel connectors. The wired VXI backplane trigger bus allows a simple way to have an event in one system trigger events in other VXI systems.

The wired trigger bus physical interface is based off of the TIA/EIA-899 Multi-Point Low Voltage Differential Signaling (M-LVDS) standard. The physical interface allows the construction of large multi-drop systems and reliable triggering over long distance. Topologies up to 6 devices over 20 m of cable are supported. The wired VXI backplane trigger bus may be capable of supporting more devices over greater cable lengths but, these configurations have not been validated by National Instruments.

The 8 triggers on the wired VXI backplane trigger bus correspond to the 8 TTL triggers on the VXI backplane (e.g., TTLTRG0* on the VXI backplane corresponds to Trigger Number 0 on the wired VXI backplane trigger bus). Each of the 8 physical trigger channels are independently configurable and can be used in one of two topologies: point-to-multipoint or multipoint-to-multipoint.

Driven Mode Operation

This is a point-to-multipoint configuration where one device on the trigger channel is configured as a driver and the remaining devices are configured as listeners. The device configured as the driver sets the state of the trigger channel and the other devices receive that state. If two or more devices are configured to drive the trigger channel the behavior of the bus is undefined.

Wired-OR Mode Operation

This is a multipoint-to-multipoint topology where multiple devices can assert a trigger channel to multiple listeners. For this topology, the trigger channel behaves in a wired-OR manner with all drivers tri-stated. A bias device is used to pull the trigger to a known, unasserted state and then the triggering device(s) drive(s) the bus to its asserted state.

Appendix D Using the Trigger Ports on the NI VXI-8360LT

LXI Compatibility

The physical and electrical interface of the wired VXI backplane trigger bus is compatible with the LXI wired trigger bus. The physical interface uses the standardized 25-pin micro-D type connector. The electrical interface uses the LXI-wired Trigger Bus cable and Terminator 2.0 specified Texas Instruments (SN65MLVD080) bus transceiver.

The LXI wired trigger bus has a much broader triggering definition and can be considered as a superset of the VXI-8360LT’s wired VXI backplane trigger bus. The two trigger domains are compatible with a few constraints:

1. All LXI devices that share the wired VXI backplane trigger bus must be configured for active high assertion of triggers whether in Driven mode or Wired-OR mode.

2. The LXI specification states that each trigger channel shall be individually configurable as an input or output (or both). The NI VXI driver software allows a trigger be mapped In to the Frame (input) or Out of the Frame (output) but not both. This constrains a single trigger to be either a driver or a receiver.

Connecting the Trigger Port Cables

The physical pinout for the two trigger ports is identical so there are no special cable connection requirements between the ports.

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

End of bus termination is required for proper operation. Use two 50 Ω resistors in series across each trigger differential pair with the center tap decoupled to ground with a capacitor. Commercially available terminators are recommended.

Configuring the Wired Trigger Bus

The 8 triggers in the wired VXI backplane trigger bus are configured via hardware and software. Hardware switches located on the top edge of the NI VXI-8360LT control the operating mode of the trigger. The factory default switch settings for all 8 triggers are displayed in Figure D-1,

1. In MAX configure the trigger to be mapped as Out of the Frame.

2. Set the trigger’s hardware switch to Driven.

Listening Device

1. In MAX configure the respective trigger lines as Into the Frame.

2. Set the trigger’s hardware switch to Receiver.

Note Do not select Receiver w/Bias Device in Driven mode. Doing so will produce

undefined results.

For Wired-Or Mode Triggers

Complete the following steps to map a trigger from the VXI backplane to the wired VXI backplane trigger bus:

Driving Device

1. In MAX configure the trigger to be mapped as Out of the Frame.

2. Set the trigger’s hardware switch to configure it as a Wired-OR.

Listening Device

1. In MAX configure the trigger to be mapped as In to Frame.

2. Set the trigger’s hardware switch to select the type of receiver needed. If the device is going to bias the wired VXI backplane trigger bus, set the trigger’s hardware switch for Receiver w/BIAS Device.

3. If the device is going to be a receiver, set the trigger hardware switch to Receiver.

Note Ensure only one receiving device is configured as the Receiver w/BIAS Device.

Having more than one bias device on a trigger channel will produce undefined results.

How to Fix an Invalid EEPROM Configuration

The NI VXI-8360T/LT controller uses an EEPROM to store configuration settings required at power on. Certain EEPROM configurations could cause your computer to lock up while booting. Generally, the size and location of memory windows will cause this issue.

Many PCI-based computers will not boot if a board in the system is requesting more memory space than the computer can allocate. If you encounter this situation you should reduce the size of the NI VXI-8360T/LT controller user memory window.

The EEPROM can also become corrupt if the NI VXI-8360T/LT controller loses power while software is updating the EEPROM.

To aid in EEPROM recovery the EEPROM is divided into two halves—one half is factory configured and the other half is user configurable. By default the VXI-MXI-Express boots from the user half of the EEPROM. Should the EEPROM become corrupt complete the following steps to restore the EEPROM to its factory settings:

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 VXI-8360T/LT controller.

2. Change jumper W5 to the position shown in Figure E-1 to restore the factory configuration. Refer to Figure B-1, VXI-MXI-Express Factory

Default Jumper Settings, of Appendix B, Advanced Hardware Configuration Settings, for jumper locations.

Figure E-1 shows the configuration settings for EEPROM operation. Use jumper W5 to control whether the NI VXI-8360T/LT controller boots off the factory-configured EEPROM settings or the user-modified settings.

3. Power on the computer. The computer should boot this time because the factory-default configuration is being used to initialize the NI VXI-8360T/LT controller.

4. Right-click on the VXI system in MAX and select the Hardware Configuration utility.

5. A dialog box will appear explaining that the Factory Override switch has been set, and the NI VXI-8360T/LT controller is running using factory default settings. Click OK to continue.

6. In the General tab under Quick Configuration select Default Configuration.

7. Click Yes in the pop up box if you are sure you want to restore the factory defaults.

8. Click OK in the hardware configuration panel to save the settings.

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

10. Change jumper W5 back to the default position, as shown in Figure E-1.

11. 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.

Common Questions

What is the maximum length of the NI VXI-8360T/LT controller MXI-Express x1 copper cable?

The maximum length for the NI VXI-8360T/LT controller MXI-Express x1 copper cable is 7 m. National Instruments offers 1 m, 3 m, and 7 m copper cables.

I need more devices than can fit in one chassis. How can I expand my NI VXI-8360T/LT controller system?

Many applications can be easily extended to multiple chassis by adding additional NI VXI-8360T/LT controllers to the host computer and using the trigger and clock sharing features of the NI VXI-8360T to synchronize events between chassis. In the event that VXI or VME bus mastering devices must communicate to devices in other chassis directly, National Instruments recommends that you use a VXI-MXI-2 interface, which implements the VXI-6 specification for mainframe extension. This extends full VXI functionality across multiple mainframes, including a common device address space, interframe triggering, interrupts, and bus mastering. Place a VXI-MXI-2 in the same mainframe with the Slot 0 NI VXI-8360T/LT controller, and another VXI-MXI-2 in Slot 0 of the next mainframe. You can then fill up this mainframe with additional devices. Refer to the MXI-2 Configuration Reference Manual available at for additional configuration instructions.

ni.com

How can I determine the serial number of the NI VXI-8360T/LT controller?

This information is displayed in the title bar of the Hardware Configuration window in MAX. The serial number can also be found on the sticker applied to the side of the controller.

Appendix G Common Questions

What is Resman?

Resman is the utility that performs the duties of a VXI Resource Manager as discussed in the VXIbus specification.

When do I need to run Resman?

Run Resman whenever you need to configure your VXI instruments (for example, when you power cycle either the host computer or the chassis).

When you set a National Instruments controller to Logical Address 0, you will at some point need to run Resman to configure your VXI instruments. If your controller uses a different (nonzero) logical address and is a message-based device, you need to start Resman before running it on the Logical Address 0 computer.

Which NI-VXI utility program must I use to configure the NI VXI-8360T/LT controller?

Use Measurement & Automation Explorer (MAX) to configure the NI VXI-8360T/LT controller. MAX is in the

National Instruments

program group folder, and a shortcut is on your desktop.

How do I handle VME devices?

Although there is no way to automatically detect VME devices in a system, you can add them easily through the Add Device Wizard in MAX. Through this procedure, you can reserve resources for each of your VME devices and configure MAX to show VME devices on the screen with all your other devices.

Which NI-VXI utility program must I use to perform startup Resource Manager operations?

Use the Resman program to perform startup Resource Manager operations in Start»Programs»National Instruments»VXI. Resman uses the settings configured in MAX. It initializes your VXI/VMEbus system and makes the information it collects accessible through MAX. You can also run Resource Manager operations from MAX. Through MAX, you can also configure Resman to run automatically at Windows startup.

VXI-MXI-Express Series User Manual G-2 ni.com

Appendix G Common Questions

What can I do to make sure that my system is up and running?

The fastest method for testing the system is to run Resman. This program attempts to access memory in the upper A16 address space of each device in the system. If Resman does not report any problems, the NI VXI-8360T/LT controller communication system is operational. To test individual devices, you can use the VIC or VISAIC program to interactively issue NI-VXI functions or NI-VISA operations, respectively. You can use

VXIinReg() and VXIout() or VXIoutReg() with the NI-VXI API) to

viIn() and viOut() with the NI-VISA API (or VXIin() or

test register-based devices by programming their registers. If you have any message-based devices, you can send and receive messages with the

viRead() and viWrite() operations in the NI-VISA API (or WSrd()

and

WSwrt() functions in the NI-VXI API). Notice that VXIinReg() and VXIoutReg() are for VXI devices only, but you can use VXIin() and VXIout() for both VXI and VME. Finally, if you are using LabVIEW or

LabWindows/CVI and you have instrument drivers for the devices in your chassis, you can use the interactive features of these programs to quickly test the functionality of the devices.

What is the accuracy of the CLK10 signal?

The CLK10 generated by the NI VXI-8360T/LT controller is ±100 ppm per the VXI specification. To use a more accurate reference for CLK10, connect the signal to the controller through the EXT CLK SMB input on the front panel.

API Application Programming Interface—the direct interface that an end user

sees when creating an application.

arbitration A process in which a potential bus master gains control over a particular

bus.

B Byte—eight related bits of data, an 8-bit binary number. Also used to

denote the amount of memory required to store one byte of data.

backplane An assembly, typically a printed circuit board, with 96-pin connectors and

signal paths that bus the connector pins. A C-size VXIbus system will have two sets of bused connectors called J1 and J2. A D-size VXIbus system will have three sets of bused connectors called J1, J2, and J3.

BERR* bus error signal

BIOS Basic Input/Output System. BIOS functions are the fundamental level

of any PC or compatible computer. BIOS functions embody the basic operations needed for successful use of the computer’s hardware resources.

block-mode transfer An uninterrupted transfer of data elements in which the master sources only

the first address at the beginning of the cycle. The slave is then responsible for incrementing the address on subsequent transfers so that the next element is transferred to or from the proper storage location. A VME data transfer may have no more than 256 elements.

bus The group of conductors that interconnect individual circuitry in a

computer. Typically, a bus is the expansion vehicle to which I/O or other devices are connected. Examples of buses include the ISA bus, PCI bus, VXI bus, and VME bus.

bus error An error that signals failed access to an address. Bus errors occur with

low-level accesses to memory and usually involve hardware with bus mapping capabilities. For example, nonexistent memory, a nonexistent register, or an incorrect device access can cause a bus error.
