Chapter 1

Introduction

•

NI-VXI Upgrade for Windows 95—this is a compatibility release

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.

NI-VXI for Windows 95—this is a fully 32-bit native Plug and

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.

•

NI-VXI for Windows NT—this is a 32-bit driver designed for

Windows NT. You can use this version to develop and run 32-bit

applications for Windows 95/NT.

Optional Software

Your VXIpc-850 kit includes the NI-VXI bus interface software. In

addition, you can use the National Instruments LabVIEW and

LabWindows/CVI application programs and instrument drivers to ease

your programming tasks. These standardized programs match the

modular virtual instrument capability of VXI and can reduce your

VXI/VMEbus software development time. These programs are fully

VXIplug&play compliant and feature extensive libraries of VXI

instrument drivers written to take full advantage of the VXI bus.

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

Chapter

Setup

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.

Chapter 2

Setup

DOS Users

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. RESMANdoes 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.

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 vxioutcommands.

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.

Glossary

address space

A set of 2 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.

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.
