that extends your NI-VXI for DOS/Windows 3.1 to allow 32-bit applications running in Windows 95 to use the 16-bit driver. In this configuration you can run both 16-bit and 32-bit applications; however, the core of the driver is 16-bit.

Play driver for Windows 95. You can run only 32-bit applications with this driver. You cannot use this driver in conjunction with either NI-VXI for DOS/Windows 3.1 or the NI-VXI Upgrade for Windows 95 to run 16-bit applications. Applications developed using this driver will run with NI-VXI for Windows NT without the need to recompile.

Windows NT. You can use this version to develop and run 32-bit applications for Windows 95/NT.

LabVIEW and LabWindows/CVI include all the tools needed for instrument control, data acquisition, analysis, and presentation. When you order the LabVIEW VXI Development System for Windows or the LabWindows/CVI VXI Development System for Windows, you also get more than 500 complete instrument drivers, which are modular, source-code programs that handle the communication with your instrument to speed your application development.

Setup

Chapter

This chapter contains basic instructions for setting up the VXIpc-850 and the NI-VXI software.

You can use this material as a guide to quickly configure and operate your VXI system using the VXIpc-850. This chapter assumes that you intend to perform a basic configuration as follows:

• You have one VXIbus chassis in which you will be using the VXIpc-850 as the Resource Manager (logical address 0).

• You will be using the NI-VXI software for initialization, configuration, and device interaction.

• You will use the default hardware and software settings.

Refer to Chapter 3 of this manual for a complete listing of the hardware and software default settings. If you need more information, or if you want to try a different configuration, please refer to the VXIpc-850

Series User Manual for information about the hardware, or to the NI-VXI Software Manual for the VXIpc-850 Series for information

about the NI-VXI software.

Hardware Installation

To prevent electrostatic discharge, touch the antistatic plastic package to a metal part of your VXIbus chassis before removing the VXIpc-850 from the package. Install the VXIpc-850 in the first slot of a VXI chassis (slot 0). The VXIpc-850 default configuration automatically detects whether it should be the VXIbus system controller. The VXIbus system controllers operate certain VXIbus lines as required for VXI systems. Verify that any other VXI devices with system controller capability that are located in the same chassis are not configured as system controller. Having more than one device configured as system controller will damage the VXI system.

Chapter 2 Setup

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.

Also ensure that no VXI devices in your system are configured for logical address 0. This is the default configuration for the VXIpc-850.

Setting up the VXIpc-850

The VXIpc-850 kit works with Windows 95/NT/3.1 or DOS, but the operating systems have different installation and configuration requirements. Be sure to observe any specific instructions for Windows 95/NT/3.1 or DOS in the following information. For more details about installing the NI-VXI software, refer to Chapter 2,

NI-VXI Software Installation, in the NI-VXI Software Manual for the VXIpc-850 Series.

Windows Users

At Windows 3.x or Windows 95 startup, you are prompted to insert a disk to configure the system for LabVIEW or LabWindows/CVI. If you ordered either of these programming environments, select the appropriate checkbox and insert the configuration disk. Follow the instructions as prompted.

Do not select either checkbox if you did not order LabVIEW or LabWindows/CVI. Instead you should click on the Next button to continue with the installation.

You will need to initialize your VXIbus system by performing the following steps.

1. Locate the NI-VXI group in the Program Manager and run the VXIinit item. This utility initializes the VXIpc-850 hardware.

♦ Windows 95 users—Because Windows 95 supports the plug and

play architecture, you do not need to run VXIinit to initialize the VXIpc-850. Proceed to step 2.

2. Execute the Resman item, which is located within the same NI-VXI group.

Getting Started with Your VXIpc-850 2-2 © National Instruments Corporation

DOS Users

Chapter 2 Setup

Although the VXIpc-850 default configuration can get Windows users up and running without any changes, DOS users must reconfigure the VXIpc-850 to operate with applications that will use the NI-VXI software for DOS. You must use the VXI Resource Editor program, either VXIedit or VXItedit, to make these necessary changes.

1. Run the VXIedit or VXItedit utility.

2. Select the VXIpc Configuration Editor from the options list.

3. Relocate the VXIpc-850 driver window to below 1 MB. Notice that the VXIedit or VXItedit utility warns you that the driver window is located above 1 MB. While this default setting is acceptable for Windows users, DOS users must enter a memory address below the 1 MB boundary to relocate the VXIpc-850 registers temporarily. Select an unused section of the Upper Memory region (usually 0xC800 to 0xE800). Notice that this memory cannot be used by another device (such as a plug-in card) or memory manager (such as EMM386.EXE). This placement is valid only while VXIedit or VXItedit is running.

4. To permanently place the board at the address, use the Bus Configuration Editor in VXIedit or VXItedit. Within this editor, set the Below 1 MB control for the driver window to Yes. In the Window Base field, select the address space to which to assign the VXIpc-850 registers.

5. Update your configuration in VXIedit or VXItedit by selecting the Update Current Configuration option from the VXIpc-850 Configuration Editor main menu.

6. Reboot your computer.

7. Execute VXIinit from the DOS prompt. This utility initializes the VXIpc-850 hardware. VXIinit also shows where the PCI Configuration Manager has placed your VXIpc-850. If this region conflicts with another board in your system, or if you experience any problems with your system, refer to the User Window and Driver Window section in Chapter 3, NI-VXI Configuration Utility, in the NI-VXI Software Manual for the VXIpc-850 Series. Notice that if you are using a memory manager (such as EMM386.EXE), you must exclude the region assigned to your VXIpc-850. This region may shift if you insert any expansion boards into the PCI expansion slot.

8. Execute RESMAN to configure your VXI system.

Chapter 2 Setup

VME Users

RESMAN identifies and configures the VXI devices. RESMAN does not configure VME devices. The VME specification does not define the initialization and configuration procedures that the VXI specification requires.

However, it is recommended that you enter the information about your VME devices into the VXIedit or VXItedit utility. RESMAN can then use this information to properly configure the various device-specific VME address spaces and VME interrupt lines. For more information on configuring non-VXI devices in your VXI system, refer to the description of the Non-VXI Device Configuration Editor in Chapter 3, VXI Resource Editor: VXIedit, of the NI-VXI Graphical Utilities Reference Manual.

Device Interaction

After RESMAN has detected and configured all VXI/VME devices, you can view specific information on each device in your system by using the VXIedit or VXItedit utilities. These utilities include a Resource Manager Display, which contains a description for each device, including each VXI device’s logical address.

You can interact with your VXI/VME devices by using the VIC or VICtext utilities. With these utilities, you can interactively control your VXI/VME devices without having to use a conventional programming language, LabVIEW, or LabWindows/CVI.

Try the following in VIC or VICtext: At the prompt:

ROOT>>

Type:

ROOT>>help vxiinreg

This help file shows you the syntax for this command, which reads VXI device configuration registers. The first argument is a logical address, and the second is the offset of the VXI device configuration register to be read.

Getting Started with Your VXIpc-850 2-4 © National Instruments Corporation

Chapter 2 Setup

Type:

ROOT>>vxiinreg 0,0

This should return a value, such as:

Return Status (0): SUCCESS. value = 0x9ff6

If the value ends with ff6, you have successfully read the National Instruments manufacturer ID from the ID register for the VXIpc-850.

You may now want to read the configuration registers from other VXI devices in your system using the command vxiinreg. This command accesses only the upper 16 KB of A16 space. Try reading the registers from one of the devices listed in the Resource Manager Display of either VXIedit or VXItedit. In this way, you can verify that your VXIpc-850 can access each of the devices in your VXI system successfully. You can also access VXI and VME devices that are configured in A16, A24, and A32 address space by using the vxiin or vxiout commands.

For more information regarding VIC operation and commands, refer to the NI-VXI Graphical Utilities Reference Manual. For more information regarding VICtext operation and commands, refer to the NI-VXI Text Utilities Reference Manual.

A16 space VXIbus address space equivalent to the VME 64 KB short

address space. In VXI, the upper 16 KB of A16 space is allocated for use by VXI devices configuration registers. This 16 KB region is referred to as VXI configuration space.

A24 space VXIbus address space equivalent to the VME 16 MB standard

address space.

A32 space VXIbus address space equivalent to the VME 4 GB extended

address space.

address Character code that identifies a specific location (or series of

locations) in memory.

Glossary

address space A set of 2n memory locations differentiated from other such sets

in VXI/VMEbus systems by six addressing lines known as address modifiers. n is the number of address lines required to uniquely specify a byte location in a given space. Valid numbers for n are 16, 24, and 32. In VME/VXI, because there are six address modifiers, there are 64 possible address spaces.

address window A portion of address space that can be accessed from the

application program. ANSI American National Standards Institute ASIC application-specific integrated circuit

B bytes 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. 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. Bus Timeout Unit A functional module that times the duration of each data transfer

and terminates the cycle if the duration is excessive. Without the

termination capability of this module, a bus master attempt to

access a nonexistent slave could result in an indefinitely long

wait for a slave response. byte order How bytes are arranged within a word or how words are

arranged within a longword. Motorola ordering stores the most

significant (MSB) byte or word first, followed by the least

significant byte (LSB) or word. Intel ordering stores the LSB or

word first, followed by the MSB or word.

between devices and internal memory without intervention of

the central processing unit. DRAM Dynamic RAM (Random Access Memory); storage that the

computer must refresh at frequent intervals. driver window A region of address space that is decoded by the VXIpc-850 for

use by the NI-VXI software.

ECL Emitter-Coupled Logic EEPROM Electronically Erasable Programmable Read Only Memory embedded controller An intelligent CPU (controller) interface plugged directly into

the VXI backplane, giving it direct access to the VXIbus. It must

have all of its required VXI interface capabilities built in.

Glossary

fair requester A VXIbus device that will not arbitrate for the VXIbus after

releasing it until it detects the bus request signal inactive. This

ensures that all requesting devices will be granted use of the bus.

hex Hexadecimal; the numbering system with base 16, using the

digits 0 to 9 and letters A to F. Hz hertz; cycles per second

IEEE Institute of Electrical and Electronics Engineers I/O input/output; the techniques, media, and devices used to achieve

communication between machines and users. interrupt A means for a device to request service from another device. interrupt handler A VMEbus functional module that detects interrupt requests

generated by interrupters and responds to those requests by

requesting status and identify information. interrupt level The relative priority at which a device can interrupt. IRQ* Interrupt signal

KB kilobytes of memory

logical address An 8-bit number that uniquely identifies each VXIbus device in

a system. It defines the A16 register address of a device, and

indicates Commander and Servant relationships.

Glossary

master A functional part of a VME/VXIbus device that initiates data

transfers on the backplane. A transfer can be either a read or a

write. MB megabytes of memory message-based device An intelligent device that implements the defined VXIbus

registers and communication protocols. These devices are able to

use Word Serial Protocol to communicate with one another

through communication registers. MITE A National Instruments custom ASIC, a sophisticated dual-

channel DMA controller that incorporates the Synchronous MXI

and VME64 protocols to achieve high-performance block

transfer rates. MTBF Mean Time Between Failure

NI-VXI The National Instruments bus interface software for

VME/VXIbus systems. Non-Slot 0 device A device configured for installation in any slot in a VXIbus

mainframe other than Slot 0. Installing such a device into Slot 0

can damage the device, the VXIbus backplane, or both.

PCI Peripheral Component Interconnect. The PCI bus is a high-

performance 32-bit or 64-bit bus with multiplexed address and

data lines.

registers. Register-based devices are typically controlled by

message-based devices via device-dependent register reads and

writes.

Glossary

RESMAN The name of the National Instruments Resource Manager in

NI-VXI bus interface software. See Resource Manager. Resource Manager A message-based Commander located at Logical Address 0,

which provides configuration management services such as

address map configuration, Commander and Servant mappings,

and self-test and diagnostic management. retry An acknowledge by a destination that signifies that the cycle did

not complete and should be repeated.

s seconds Servant A device controlled by a Commander; there are message-based

and register-based Servants. Shared Memory Protocol A communication protocol that uses a block of memory that is

accessible to both a client and a server. The memory block

operates as a message buffer for communications. SIMM Single In-line Memory Module slave A functional part of a VME/VXIbus device that detects data

transfer cycles initiated by a VMEbus master and responds to the

transfers when the address specifies one of the device’s registers. Slot 0 device A device configured for installation in Slot 0 of a VXIbus

mainframe. This device is unique in the VXIbus system in that it

performs the VMEbus System Controller functions, including

clock sourcing and arbitration for data transfers across the

backplane. Installing such a device into any other slot can

damage the device, the VXIbus backplane, or both.

trigger Either TTL or ECL lines used for intermodule communication. TTL Transistor-Transistor Logic

Glossary

user window A region of address space reserved by the VXIpc-850 for use via

the NI-VXI low-level function calls. MapVXIAddress() uses

interface software package. Used to program VXI devices, and

develop and debug VXI application programs. VME Versa Module Eurocard or IEEE 1014 VMEbus System Controller A device configured for installation in Slot 0 of a VXIbus

mainframe or Slot 1 of a VMEbus chassis. This device is unique

in the VMEbus system in that it performs the VMEbus System

Controller functions, including clock sourcing and arbitration for

data transfers across the backplane. Installing such a device into

any other slot can damage the device, the VMEbus/VXIbus

backplane, or both. VXIbus VMEbus Extensions for Instrumentation VXIedit or VXItedit VXI Resource Editor program, a part of the NI-VXI bus

interface software package. Used to configure the system, edit

the manufacturer name and ID numbers, edit the model names of

VXI and non-VXI devices in the system, as well as the system

interrupt configuration information, and display the system

configuration information generated by the Resource Manager. VXIinit A program in the NI-VXI bus interface software package that

initializes the board interrupts, shared RAM, VXI register

configurations, and bus configurations.

Glossary

Word Serial Protocol The simplest required communication protocol supported by

message-based devices in a VXIbus system. It utilizes the A16

communication registers to transfer data using a simple polling

handshake method. write posting A mechanism that signifies that a device will immediately give a

successful acknowledge to a write transfer and place the transfer

in a local buffer. The device can then independently complete

the write cycle to the destination.
