Compliance  
FCC/Canada Radio Frequency Interference Compliance*  
Determining FCC Class  
The Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCC  
places digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only)  
or Class B (for use in residential or commercial locations). Depending on where it is operated, this product could be subject to  
restrictions in the FCC rules. (In Canada, the Department of Communications (DOC), of Industry Canada, regulates wireless  
interference in much the same way.)  
Digital electronics emit weak signals during normal operation that can affect radio, television, or other wireless products. By  
examining the product you purchased, you can determine the FCC Class and therefore which of the two FCC/DOC Warnings  
apply in the following sections. (Some products may not be labeled at all for FCC; if so, the reader should then assume these are  
Class A devices.)  
FCC Class A products only display a simple warning statement of one paragraph in length regarding interference and undesired  
operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locations where FCC Class A  
products can be operated.  
FCC Class B products display either a FCC ID code, starting with the letters EXN,  
or the FCC Class B compliance mark that appears as shown here on the right.  
Consult the FCC web site http://www.fcc.gov for more information.

Introduction  
Benefits of PXI  
The PXIbus specification defines a compact modular PC platform for  
industrial instrumentation. PXI leverages the PCI bus, which is the de facto  
standard for todays desktop computer software and hardware designs. As  
a result, PXI users receive all the benefits of PCI within an architecture that  
supports mechanical, electrical, and software features tailored to industrial  
instrumentation, data acquisition, and automation applications.  
Well-suited for industrial applications, PXI leverages from the  
CompactPCI specification, which defines a rugged form factor for PCI that  
offers superior mechanical integrity and easy installation and removal of  
hardware components. PXI products offer higher and more carefully  
defined levels of environmental performance required by the vibration,  
shock, temperature, and humidity extremes of industrial environments.  
PXI adds mandatory environmental testing and active cooling to the  
CompactPCI mechanical specification to ease system integration and  
ensure multivendor interoperability.  
Additionally, PXI meets the more specific needs of instrumentation users  
by adding an integrated trigger bus and reference clock for multiple-board  
synchronization, a star trigger bus for very precise timing, and local buses  
for side-band communication between adjacent peripherals.  
NI 8171 Series  
Description  
The NI 8171 series PXI/CompactPCI embedded computer is a  
high-performance PXI/CompactPCI-compatible system controller. The  
NI 8171 series controllers integrate standard I/O features in a single unit by  
using state-of-the-art packaging. Combining a NI 8171 series embedded  
controller with a PXI-compatible chassis, such as the PXI-1000B, results in  
a fully PC-compatible computer in a compact, rugged package.

Introduction  
National Instruments Software  
National Instruments has developed several software kits you can use with  
the NI 8171 series. The software is already installed on your hard drive.  
NI-DAQ has an extensive library of functions that you can call from your  
application programming environment. These functions include routines  
for analog input (A/D conversion), buffered data acquisition (high-speed  
A/D conversion), analog output (D/A conversion), waveform generation,  
digital I/O, counter/timer operations, SCXI, RTSI, self-calibration,  
messaging, and acquiring data to extended memory.  
NI-VISA is the National Instruments implementation of the VISA  
specification. VISA is a uniform API for communicating and controlling  
Serial, GPIB, PXI, VXI, and various other types of instruments. This API  
aids in the creation of more portable applications and instrument drivers.  
For information on writing your own PXI instrument driver with NI-VISA,  
see the NI-VISA Getting Started manual and the readme.txt file in the  
NI-VISA directory.  
You can also use the National Instruments LabVIEW and Measurement  
Studio application programs and instrument drivers to ease your  
programming task. These standardized programs match the modular virtual  
instrument capability of PXI and can reduce your PXI software  
development time. These programs feature extensive libraries of GPIB,  
Serial, and VXI instrument drivers written to take full advantage of direct  
PXI control. LabVIEW and Measurement Studio 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  
have to spend time programming the low-level control of each instrument.  
Measurement Studio bundles LabWindows/CVI for C programmers,  
ComponentWorks for Microsoft Visual Basic programmers, and  
ComponentWorks++ for Microsoft Visual C++ programmers.  
Measurement Studio is designed for building measurement and automation  
applications with the programming environment of your choice:

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.  
ComponentWorks for Visual Basic is a collection of ActiveX controls  
designed for building virtual instrumentation systems. Based on  
ActiveX technology, ComponentWorks controls are configured  
through simple property pages. You can use the ComponentWorks  
GPIB, Serial, and VISA I/O controls and property pages to set up  
communication with your instruments.  
ComponentWorks++ for Visual C++ takes advantage of integrated  
C++ libraries and ActiveX to help you build measurement and  
automation applications. With the ComponentWorks++ instrument  
classes, you can use the IEEE 488.2 library and VISA, an  
industry-standard I/O library, to communicate with GPIB, VXI, PXI,  
TCP/IP, or Serial devices using the same set of components.

Installation and Configuration  
This chapter contains information about installing and configuring your  
NI 8171 series controller.  
Installing the NI 8171 Series  
This section contains general installation instructions for the NI 8171  
series. Consult your PXI chassis user manual for specific instructions and  
warnings.  
1. Plug in your chassis before installing the NI 8171 series. The power  
cord grounds the chassis and protects it from electrical damage while  
you install the module. (Make sure the power switch is turned off.)  
Caution To protect both yourself and the chassis from electrical hazards, leave the chassis  
off until you finish installing the NI 8171 series module.  
2. Remove any filler panels blocking access to the system controller slot  
(Slot 1) in the chassis.  
3. Touch the metal part of the case to discharge any static electricity that  
might be on your clothes or body.  
4. Make sure the injector/ejector handle is in its downward position.  
Align the NI 8171 series with the card guides on the top and bottom of  
the system controller slot.  
Caution Do not raise the injector/ejector handle as you insert the NI 8171 series. The  
module will not insert properly unless the handle is in its downward position so that it does  
not interfere with the injector rail on the chassis.  
5. Hold the handle as you slowly slide the module into the chassis until  
the handle catches on the injector/ejector rail.  
6. Raise the injector/ejector handle until the module firmly seats into the  
backplane receptacle connectors. The front panel of the NI 8171 series  
should be even with the front panel of the chassis.  
7. Tighten the four bracket-retaining screws on the top and bottom of the  
front panel to secure the NI 8171 series to the chassis.

How to Remove the Controller from the PXI Chassis  
The NI 8171 series controllers are designed for easy handling. To remove  
the unit from the PXI chassis:  
1. Turn off power.  
2. Remove the bracket-retaining screws in the front panel.  
3. Press the injector/ejector handle down.  
4. Slide the unit out of the chassis.  
BIOS Setup  
You can change the NI 8171 series 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 8171 series controller features.  
Most users do not need to use the BIOS setup program, as the NI 8171  
series 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  
To start the BIOS setup utility:  
1. Turn on or reboot your NI 8171 series controller.  
2. When the message Press <DEL> to enter SETUP appears, press  
<Delete> or <Del> on the numeric keypad. The message Entering  
Setup… appears, and the setup program is loaded after a short delay.  
3. When you first enter the BIOS setup program, it displays the Main  
menu.  
Use the following keys to navigate through the BIOS setup:  
Left Arrow, Right ArrowUse these keys to move between the  
different setup menus. If you are in a submenu, these keys have no

The most commonly accessed and modified BIOS settings are in the Main  
setup menu. The Main setup menu includes the following settings:  
System Time & DateThis setting controls the time of day, which is  
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> to change these values.  
DMI Event LoggingThis setting brings up the DMI Event  
Logging submenu (see the DMI Event Logging Submenu section).  
Keyboard Required to BootWhen Yes, a missing or  
malfunctioning keyboard causes the BIOS to halt with an error. When  
No, the BIOS allows booting without a keyboard, and you can attach a  
keyboard at any time during the powered up state. To use this controller  
in a headlessmode, you must set this option to No. The default value  
is Yes.  
Num LockThis setting indicates whether you turn on Num Lock at  
boot time. The default value is On.  
Primary/Secondary Master/SlaveThese items display the  
IDE/ATA devices detected in the system. Normally, you do not need to  
modify these items. However, if an IDE/ATA device is not  
autodetected properly, you can specify it manually by pressing  
<Enter> on an item.  
System InformationThis setting displays a screen containing  
important system information about the NI 8171 series controller.

DMI Event Logging Submenu  
Major errors that occur during the BIOS booting process are stored in  
battery-backed memory on the controller, and remain there until you view  
and clear them using this submenu. This logging capability allows a system  
administrator to detect the historical occurrence of faults on a controller.  
This submenu includes the following items:  
View DMI Event LogThis setting displays a window containing all  
logged system errors and the time at which they occurred.  
Mark Events as ReadThis setting prevents any current logged  
entries from being displayed again. However, all entries remain in  
battery-backed memory, and you can retrieve them using other DMI  
software that is beyond the scope of this document.  
Clear All EventsWhen set to Yes, this setting clears all entries from  
the DMI event log on reboot.  
Event LoggingThis setting controls whether events are logged.  
Disabling logging has no impact on system performance. The default  
is Enabled.  
Advanced Setup Menu  
This menu contains BIOS settings that normally do not require  
modification. If you have specific problems such as unbootable disks or  
resource conflicts, you may need to examine these 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 DataA 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 PeripheralsUse this setting to bring up the Integrated  
Peripherals submenu (see the Integrated Peripherals Submenu  
section).  
Local Bus IDE AdapterThe NI 8171 series controller has two  
integrated IDE/ATA channels (Primary and Secondary), each capable

Installation and Configuration  
of supporting two ATA devices (Master and Slave). Use this setting to  
disable one or more of these integrated channels. You should modify  
this setting only if specified in other sections of this manual. The  
default is Both.  
Write Protect Boot SectorWhen set to Yes, this setting prevents  
modification of a hard disk boot sector via INT 13h services, which  
may help prevent certain computer viruses from infecting the  
controller. This setting does not prevent boot sector modification by  
32-bit operating system drivers that access the hard disk directly. The  
default is No.  
Quick Boot ModeWhen you enable this option, certain lengthy  
BIOS tests that rarely fail are skipped to shorten controller boot time.  
The default is Enabled.  
Summary ScreenThis 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.  
Integrated Peripherals Submenu  
Use this submenu to apply nondefault configurations to the front panel  
peripherals of an NI 8171 series 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 & BThis setting enables or disables COM1 and  
COM2, respectively. You can also 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 and COM2  
at 0x2F8 IRQ 3.  
Parallel PortUse this setting to enable or disable LPT1. You can  
also 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.  
Parallel Port ModeThe 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.  
Floppy DriveYou can route the internal signals used for the 3.5 in.  
floppy drive operation through the pins on the parallel port connector.  
Use this setting to operate the NI 8171 series controller with a

specialized external floppy drive. Normally, using a Universal Serial  
Bus (USB) floppy drive is preferable to this option, which requires a  
specially designed drive and cable. (See the Parallel Port section in  
Chapter 3, I/O Information, for pinout information.) Setting this option  
to Parallel Port disables normal LPT1 functionality. The Default is  
Enabled, which routes the signals to the standard internal floppy drive.  
Legacy USB SupportUse 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 the BIOS Setup program, and when  
using operating systems with no USB support. Certain real-time  
applications may require you to disable this setting to reduce loop time  
jitter. The default is Enabled.  
PXI Setup Menu  
Use this menu to control and route certain signals on the PXI backplane, as  
well as enable the LCD display for a PXI-1020 or PXI-1025 chassis.  
Normally, you do not need to modify these settings. However, other  
sections of this manual may indicate that modifications are necessary and  
may lead to unpredictable behavior.  
INTP RoutingYou can route INTP to ISA IRQ 14, for use by a PXI  
device functioning as a Primary IDE Controller. The default setting is  
Not Routed.  
INTS RoutingYou can route INTS to ISA IRQ 15, for use by a PXI  
it to the controllers 21-frame serialized IRQ input, for use by certain  
PXI carrier cards. The default setting is Not Routed.  
LCD DisplayThis setting allows the integrated LCD display of a  
PXI-1020 or PXI-1025 chassis to function as the primary display  
device for the NI 8171 series controller. See the Using the Controllers  
with PXI-1020 and PXI-1025 Chassis section for more information.  
The default is Disabled. This option is present only if the chassis has  
an integrated LCD.  
Note If INTS or INTP is routed to an ISA IRQ, you must disable one or both channels of  
the integrated IDE/ATA controller for correct operation of this routing.

Installation and Configuration  
Security Setup Menu  
Use this menu to apply system-level passwords to the NI 8171 series  
controller. With these passwords, you can restrict access to the BIOS setup  
program, floppy drives, and operating systems installed on bootable  
devices. If you forget any password, you can restore the CMOS contents to  
the factory default as described in the System CMOS section of this manual.  
Note In most chassis configurations, an unauthorized user has easy access to the jumper  
that resets the CMOS contents to the factory default. For a secure setup of this controller,  
National Instruments recommends further provisions that are beyond the scope of this  
document.  
The Security setup menu includes the following settings:  
Set Supervisor PasswordThis setting sets the password that  
governs supervisor-level access to the BIOS setup screen and booting.  
The default is no password.  
Set User PasswordThis setting sets the password that governs  
user-level access to the BIOS setup screen and booting. If you enter  
BIOS setup using the user password, the only BIOS setting you can  
modify is the user password. The default is no password.  
Password on BootThis setting controls whether the controller  
requires a supervisor or user password to boot an operating system. If  
you enter the supervisor password on boot, you have supervisor-level  
diskette access. If you enter the user password on boot, you have  
user-level diskette access.  
Diskette AccessThis setting controls which level of access is  
required to access the floppy drive via INT 13h services. This setting  
has no effect on 32-bit operating systems drivers that access the floppy  
disk directly. The default is Supervisor.  
Note To disable a current password, leave the new password field blank by simply  
pressing <Enter> on the field.  
Boot Setup Menu  
This screen displays the boot order of devices associated with the  
controller. The BIOS proceeds down this list in search of a bootable device.  
If the BIOS fails to find any bootable device, the message Operating  
System Not Found is displayed, and the system halts.  
Removable DevicesThe boot list includes all classes of floppy and  
ZIP drives, both internal and USB-based devices.

Network BootThis option is for National Instruments controllers  
with PXE ROM. The NI-8171 ENET controller will support this  
option in the future.  
Note If an SCSI host adapter exists in the system, this menu has an additional entry for  
SCSI devices.  
Exiting BIOS Setup  
The Exit setup menu includes all available options for exiting, saving, and  
loading the BIOS default configuration. As an alternative to this screen, use  
<F9> to load BIOS default settings and <F10> to save changes and exit  
setup.  
The Exit setup menu includes the following settings:  
Exit Saving ChangesAny changes made to BIOS settings are stored  
in the battery-backed System CMOS. The setup program then exits  
and reboots the controller.  
Exit Discarding ChangesAny changes made to BIOS settings  
during this session of the BIOS setup program are discarded. The setup  
program then exits and boots the controller without rebooting first.  
Load Setup DefaultsThis setting restores all BIOS settings to the  
factory default. This is useful if the controller exhibits unpredictable  
behavior due to an incorrect or inappropriate BIOS setting. Note that  
any nondefault settings such as boot order, passwords, and  
keyboardless operation are restored to their factory defaults. This may  
produce undesirable behavior, and in heavily customized cases, may  
cause the controller to malfunction or fail to boot.  
Discard ChangesAny changes made to BIOS settings during this  
session of the BIOS setup program are discarded. Unlike Exit  
Discarding Changes, however, the BIOS setup continues to be active.  
Save ChangesChanges made to BIOS settings during this session  
are committed to battery-backed System CMOS. The setup program  
remains active, allowing further changes.

Chassis Mouse and Keyboard  
The PXI-1020 has an integrated PS/2 mouse. The PXI-1025 has an  
integrated PS/2 keyboard and mouse. To simplify configuration for these  
chassis, the NI 8171 series includes an internal USB-to-PS/2 adapter. When  
the NI 8171 series is installed in a PXI-1020 or PXI-1025 chassis, the  
USB-to-PS/2 adapter is enabled automatically. With this adapter, you can  
use both the chassisintegrated keyboard/mouse and the PS/2 keyboard and  
mouse connected to the NI 8171 series front panel. To enable  
keyboard/mouse access in DOS or Windows NT environments, you must  
enable the legacy USB. See the Advanced Setup Menu section for more  
information.  
Drivers and Software  
Files and Directories Installed on Your Hard Drive  
Your hard drive includes a directory called images in its root that  
contains software and soft copies of manuals for the peripherals. The  
directory structure under the images directory is logically organized into  
several levels.  
In the images directory itself, you will find a manuals directory,  
an os directory, and directories for each computer peripheral.  
The manuals directory contains quick reference guides, technical  
reference manuals, and National Instruments software manuals, all in  
Adobe Acrobat format. To access any manual, change your directory to  
c:\images\pxi8171\manuals and list the contents of that directory.  
You will see several files, one corresponding to each peripheral.  
The os directory contains a subdirectory corresponding to the operating  
system installed on your computer.  
The rest of the directories correspond to each peripheral in your system.  
Within each of these directories are the drivers for the peripherals. These  
files and directories are copied exactly from the manufacturer distribution  
disks, so the naming conventions vary from peripheral to peripheral.  
Because the naming conventions may not be completely straightforward,  
National Instruments provides a text file named drivers.txt in the  
c:\images\pxi8171 directory. The drivers.txt file explains how  
to install support for each peripheral. You may want to print this file for  
reference when you install your peripheral device drivers.

PXI Features  
PXI Trigger Connectivity  
The SMB connector on the NI 8171 series front panel can connect to or  
from any PXI backplane trigger line through software. A trigger allocation  
process is needed to prevent two resources from connecting to the same  
trigger line, resulting in the trigger being double-driven and possibly  
damaging the hardware. At the time of this manuals publication, this  
software is not yet available; however, an interim trigger routing software  
utility is available from National Instruments. Contact National  
Instruments for more information.  
Upgrading RAM  
You can change the amount of installed RAM on the NI 8171 series by  
upgrading the SO-DIMM.  
To upgrade the RAM, remove the NI 8171 series from the PXI chassis.  
Remove the old SO-DIMM module and install the new SO-DIMM in the  
socket as shown in Figure 2-3.  
National Instruments offers the following types of SO-DIMMs for use with  
the NI 8171 series controller.  
128 MB, 16MB × 64, 7.5 ns, 1.05 in. max  
256 MB, 32MB × 64, 7.5ns, 1.05 in. max  
Note National Instruments has tested and verified that the SO-DIMMs we sell work with  
the NI 8171 series. We recommend you purchase your SO-DIMM modules from National  
Instruments. Other off-the-shelf SO-DIMM modules are not guaranteed to work properly.

Hard Drive Recovery  
The NI 8171 series controllers include a recovery CD. There are two  
methods for recovering the hard disk to its original state.  
Recovery from a CD-ROM  
These steps apply to a USB CD-ROM, IDE CD-ROM (when using a  
PXI-1020 or PXI-1025 chassis), or SCSI CD-ROM drive (when a SCSI  
adapter is installed).  
To recover the hard disk from a CD-ROM:  
1. Load the recovery CD into the CD-ROM drive.  
2. Press <Esc> during the BIOS POST. After POST, a boot menu is  
displayed. Select the CD-ROM drive.

3. The BIOS boots from CD-ROM drive. Follow the prompts to recover  
the hard drive.  
Note Not all CD-ROMs are bootable with the NI 8171 series controllers. For a complete  
list of USB CD-ROM drives that National Instruments has verified as bootable, see  
ni.com/support/pxisupp.htm.  
Recovery from a Network  
To recover the hard disk from a network:  
1. Create a DOS boot disk with network support. (The DOS network  
drivers and a network boot disk example are on the recovery CD.)  
2. Use another PC on the network with a CD-ROM drive. Share the drive  
and load the recovery CD.  
3. Boot the NI 8171 series using the network boot disk. Run the net utility  
from the a drive.  
4. Map the shared CD-ROM drive to K:.  
5. Run k:\recover.bat. Follow the prompts to recover the hard drive.  
Installing an OS  
NI 8171 series controllers include a preinstalled OS. In some cases, you  
may want to reinstall the OS or install a different OS. When doing so,  
considering the following guidelines.  
Installing from a CD-ROM  
Although the NI 8171 series can boot from a USB CD-ROM, you cannot  
install most operating systems from a USB CD-ROM drive. For example,  
Windows 2000 aborts during the install process because it does not have  
drivers for the CD-ROM device.  
With DOS drivers, you can install Windows 9x operating systems.  
However, only a few USB CD-ROM drives have DOS drivers.  
National Instruments does not recommend using a USB CD-ROM drive for  
CD-ROM OS installations. However, you can use a PXI-1020 or PXI-1025  
chassis with an integrated IDE CD-ROM drive, or an external SCSI  
CD-ROM with a PXI-SCSI adapter.

Common Configuration Questions  
This chapter answers common configuration questions you may have when  
using the NI 8171 series embedded controller.  
General Questions  
What do the LEDs on the NI 8171 series front panel mean?  
The green LED indicates the power supplies to/on the NI 8171 series are  
within spec. The supplies monitored are 3.3 V, 5 V, +12 V, and the internally  
regulated processor core voltage. The hard drive LED lights when there is  
hard drive activity on the NI 8171 series.  
How do I check the configuration of the memory, floppy drive, hard  
drive, time/date, and so on?  
You can view these parameters in the BIOS setup. To enter the BIOS setup,  
reboot the NI 8171 series and press <Delete> during the memory tests. See  
the Entering BIOS Setup section in Chapter 2, Installation and  
Configuration, for more information.  
Can I use the internal IDE drive and an external SCSI hard drive at  
the same time?  
Yes.  
Boot Options  
What devices can I boot from?  
The NI 8171 series can boot from the following devices:  
The internal IDE hard drive.  
The internal 1.44 MB floppy drive.  
The internal IDE CD-ROM in a PXI-1020 or PXI-1025 chassis.  
An external SCSI hard drive or CD-ROM if an SCSI adapter, such as  
the PXI-8210, is used.

Common Configuration Questions  
An external USB mass storage device such as a USB hard drive or  
CD-ROM.  
An external USB floppy drive.  
Note There are some limitations when booting from a USB device. Windows does not  
support booting from USB devices. The NI 8171 series BIOS configures the USB devices  
so they will work in a DOS environment. Due to the Windows limitation, you also cannot  
install the OS from a USB CD-ROM.  
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 <Esc> 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.  
Cables and Connections  
How do I plug both a PS/2 mouse and PS/2 keyboard into the  
controller?  
The NI 8171 series has a combined PS/2 mouse and PS/2 keyboard  
connector, so you need to use the PS/2 Y-splitter cable shipped with the  
NI 8171 series, shown in Figure 4-1, to connect both a PS/2 mouse and  
PS/2 keyboard.

Chapter 4  
Common Configuration Questions  
What if I dont have a Y-splitter cable? Can I still use a mouse and  
keyboard?  
If you do not have a Y-splitter cable, plug a PS/2 keyboard into the PS/2  
combo connector. However, you cannot use a PS/2 mouse without the  
Y-splitter, so use a serial or USB mouse.  
How do I connect a standard 25-pin LPT cable to the NI 8171 series?  
The NI 8171 series uses a type C LPT connector. Most parallel port devices  
use a type A connector. To use a device with a standard type A LPT  
connector, you need to use a type C-to-type A LPT adapter. To order  
the adapter, see the online catalog at ni.com.  
Operating System and Software Driver Installation  
How do I install or reinstall the video driver?  
See the Drivers.txt file on the hard drive or recovery CD-ROM.  
How do I install or reinstall the Ethernet driver?  
See the Drivers.txt file on the hard drive or recovery CD-ROM.  
How do I install or reinstall the GPIB driver?  
1. The best way to set up GPIB is to set up networking on your controller  
so you can access ni.com to download the latest drivers. You can  
access both of these drivers by going to the current Drivers and  
Updates page.  
2. Once these drivers are installed, go into the Device Manager in the  
System Properties window, delete the PCI Bridge and PCI  
Communication Device entries under Other Devices, and reboot the  
controller.  
3. When the controller reboots, it will correctly find and install the proper  
drivers for the GPIB adapter.  
How do I install software from a CD?  
The compact size of the NI 8171 series does not allow for an integrated  
CD-ROM drive. If you are using Windows 2000, you have the following  
options:  
USB CD-ROMWindows 2000 supports USB mass storage devices.  
With most USB CD-ROM drives, once you plug the drive into the USB  
port, you should be able to access the drive through a drive letter.

Hard Drive Recovery  
How do I restore the hard drive image?  
The NI 8171 series controllers include a recovery CD. There are two  
methods for recovering the hard disk to its original state.  
Recovery from a CD-ROM Drive  
These steps apply to a USB CD-ROM, IDE CD-ROM (when using a  
PXI-1020 or PXI-1025 chassis), or SCSI CD-ROM drive (when a SCSI  
adapter is installed).  
To recover the hard disk from a CD-ROM:  
1. Load the recovery CD into the CD-ROM drive.  
2. Press <Esc> during the BIOS POST. After POST, a boot menu is  
displayed. Select the CD-ROM drive.  
3. The BIOS boots from CD-ROM drive. Follow the prompts to recover  
the hard drive.  
Note Not all CD-ROMs are bootable with the NI 8171 series controllers. For a complete  
list of USB CD-ROM drives that National Instruments has verified as bootable, see  
ni.com.  
Recovery from a Network  
To recover the hard disk from a network:  
1. Create a DOS boot disk with network support. (The DOS network  
drivers and a network boot disk example are on the recovery CD.)  
2. Use another PC on the network with a CD-ROM drive. Share the drive  
and load the recovery CD.  
3. Boot the NI 8171 series using the network boot disk. Run the net utility  
from the a drive.

4. Map the shared CD-ROM drive to K:.  
5. Run k:\recover.bat. Follow the prompts to recover the hard drive.  
Chassis Configuration  
How do I set up the NI 8171 series to work with a PXI-1020 or  
PXI-1025 chassis?  
The NI 8176 and NI 8175 controllers interface directly to the National  
Instruments PXI-1020 and PXI-1025 chassis. The interface contains  
signals to interface to the chassis LCD display, IDE CDROM drive, and  
PS/2 mouse and keyboard.  
LCD Display  
To enable/disable the LCD display for a PXI-1020 or PXI-1025 chassis:  
1. Install the controller in a PXI-1020 or PXI-1025 chassis.  
2. Connect a CRT monitor to the VGA connector on the NI 8171 series  
controller.  
3. Power on the chassis and enter the BIOS setup program during the  
boot. (When the message Press <DEL> to enter SETUP appears,  
press <Delete> or <Del> on the numeric keypad. The message  
Entering Setupappears, and the setup program is loaded after  
a short delay.)  
4. In the PXI Setup menu, set the LCD chassis setting to the correct  
value.  
PXI-1020Enables the LCD display and sets the resolution to  
640 × 480.  
PXI-1025Enables the LCD display for the PXI-1025 chassis  
and sets the resolution to 800 × 600.  
DisabledDisables the LCD display even if the controller is  
installed in a PXI-1020 or PXI-1025 chassis.  
IDE CD-ROM Drive  
The PXI-1020 and PXI-1025 chassis have integrated CD-ROM drives. The  
BIOS automatically detects the CD-ROM and enables the IDE interface.  
The OS loads drivers to access the CD-ROM. Refer to the Boot Options  
section for information on booting from the CD-ROM drive.

Common Configuration Questions  
Chassis Mouse and Keyboard  
The PXI-1020 has an integrated PS/2 mouse. The PXI-1025 has an  
integrated PS/2 keyboard and mouse. To simplify the configuration for  
these chassis, the NI 8171 series includes an internal USB-to-PS/2 adapter.  
When the NI 8171 series is installed in a PXI-1020 or PXI-1025 chassis,  
the USB-to-PS/2 adapter is enabled automatically. With this adapter, you  
can use both the chassisintegrated keyboard/mouse and the PS/2 keyboard  
and mouse connected to the NI 8171 series front panel. To enable  
keyboard/mouse access in DOS or Windows 2000 environments, you  
must enable the legacy USB. See the Boot Options section for more  
information.  
How do I set up the NI 8171 series to work with my chassis?  
A pxisys.ini file is associated with each chassis. This file allows  
software applications such as Measurement & Automation Explorer  
(MAX) to identify the slot number for each board in the chassis.  
You need the correct pxisys.ini file for your chassis. You can find these  
files at ni.com/support/pxisupp.htm.. (Some chassis .ini files are  
also included on the PXI System Initialization for NI 8171 floppy disk  
included with the NI-8171 series controller.) Copy the file to the C:\WINNT  
directory.  
Upgrade Information  
How do I upgrade system memory?  
You can change the amount of installed RAM on the NI 8171 series by  
upgrading the SO-DIMM.  
To upgrade the RAM, remove the NI 8171 series from the PXI chassis.  
Remove the old SO-DIMM module and install the new SO-DIMM in the  
socket as shown in Figure 4-2.  
National Instruments offers the following types of SO-DIMMs for use with  
the NI 8171 series controller.  
128 MB, 16MB × 64, 7.5 ns, 1.05 in. max  
256 MB, 32MB × 64, 7.5ns, 1.05 in. max  
Note National Instruments has tested and verified that the SO-DIMMs we sell work with  
the NI 8171 series. We recommend you purchase your SO-DIMM modules from National  
Instruments. Other off-the-shelf SO-DIMM modules are not guaranteed to work properly.

Common Configuration Questions  
The LPT port on the NI 8171 series can also be configured through the  
BIOS setup for floppy signals instead of LPT signals. See Chapter 3, I/O  
Information, for the floppy drive pinout.  
Windows NT4 Issues  
Does Windows NT4 support USB and plug and play?  
National Instruments recommends using a USB CD-ROM for software  
installation when using Windows 2000. However, Windows NT4 does not  
natively support USB. When using Windows NT4, National Instruments  
does not recommend USB CD-ROMs or other USB devices. (USB  
keyboards and USB mice will work with Windows NT4 when legacy  
USB is enabled in the BIOS.)  
Windows NT4 is not a plug and play OS. Therefore, driver installation is  
more difficult on Windows NT4 than on Windows 2000.  
PXI Configuration  
How do I use the SMB trigger on the front panel?  
The SMB connector on the NI 8171 series front panel can connect to or  
from any PXI backplane trigger line through software. A trigger allocation  
process is needed to prevent two resources from connecting to the same  
trigger line, resulting in the trigger being double-driven and possibly  
damaging the hardware. At the time of this manuals publication, this  
software is not yet available; however, an interim trigger routing software  
utility is available from National Instruments. Contact National  
Instruments for more information.  
Why doesnt the NI 8171 series work with the PXI-8220?  
A serialized IRQ conflict with the PXI-8220 and the NI 8171 series  
prevents PC cards using ISA interrupts from working with the NI 8171  
series controllers. Contact National Instruments for information about new  
PC card and cardbus adapters for PXI that work with the NI 8171 series.

Troubleshooting  
This chapter answers common troubleshooting questions you may have  
when using the NI 8171 series embedded computer.  
What if the NI 8171 series does not boot?  
Several problems can cause a controller not to boot. Here are some things  
to look for and possible solutions.  
Things to Notice  
Which LEDs come on? The Power OK LED should stay lit. The  
Drive LED should blink during boot as the disk is accessed.  
What appears on the display? Does it hang at some particular point  
(BIOS, Operating System, etc.)? If nothing appears on the screen, try  
a different monitor. Does your monitor work with a different PC? If it  
hangs, note the last screen output that you saw for reference when  
consulting National Instruments technical support.  
What has changed about the system? Did you recently move the  
system? Was there electrical storm activity? Did you recently add a  
new module, memory chip, or piece of software?  
Things to Try  
Make sure the chassis is plugged in to a working power source.  
Check any fuses or circuit breakers in the chassis or other power  
supply (possibly a UPS).  
Make sure the controller module is firmly seated in the chassis.  
Remove all other modules from the chassis.  
Remove any nonessential cables or devices.  
Try a similar controller in this same chassis.  
Recover the hard drive on the controller. (See the Hard Drive Recovery  
section in Chapter 4, Common Configuration Questions.)  
Clear the CMOS. (See the System CMOS section in Chapter 2,  
Installation and Configuration.)

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 synch 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>.  
For Windows NT, select Windows NT (VGA MODE) from the boot  
manager. You should now be able to reset the video driver to lower settings.  
Try setting the resolution to 640x480 and the refresh rate to 60Hz. Once  
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 system boots fine as long as a particular module is not in my  
chassis.  
The most common cause of this is a damaged module. Try the module in a  
different chassis or with a different controller. Also, remove any external  
cables or terminal blocks connected to the system. If the module does not  
work in these cases, it is likely damaged. Contact the module manufacturer  
for further troubleshooting.  
See the KnowledgeBase or product manuals section at ni.com for more  
information specific to the chassis and controller with which you are having  
difficulties.  
How do I restore the operating system on a my NI 8171 series  
controller?  
The NI 8171 series controllers include a recovery CD. There are two  
methods for recovering the hard disk to its original staterecovery from a  
CD-ROM or from a network. For more information, see the Recovery from  
a CD-ROM or Recovery from a Network sections in Chapter 2, Installation  
and Configuration.  
My CMOS is corrupted. How do I set it back to default?  
1. Enter the BIOS setup program as described in the Entering BIOS Setup  
section of Chapter 2, Installation and Configuration.  
2. Press <F9> to load BIOS defaults.  
3. Answer Y (Yes) to the verification prompt.  
4. Select Save and Exit Setup.

Troubleshooting  
I cant change the display on the NI 8171 series controller from  
640 × 480 to 800 × 600. Whats wrong?  
If you are using a PXI-1020 or PXI-1025 chassis, the integrated LCD limits  
the maximum resolution displayed.  
If you are not using a PXI-1020 or PXI-1025 chassis, be sure the video  
driver is installed. If it is not, see the Drivers.txt file on the hard drive  
or recovery CD-ROM.  
What if there is a power loss during a BIOS update?  
Create a crisis recovery disk. Unzip crisis.zip on the recovery CD.  
Insert a blank floppy disk in the PC. Run crisis.exe (or  
Wincrisis.exe in Windows). Follow the instructions to create the BIOS  
recovery floppy disk. Insert the disk in the NI 8175 or NI 8176 floppy drive  
and power on the controller. The controller installs the BIOS from the disk.
