Introduction
This chapter provides overview information for PXI and the NI PXI-8820
embedded controller.
Benefits of PXI
The PXI (PCI eXtensions for Instrumentation) industry standard, an open
specification governed by the PXI Systems Alliance (PXISA), defines a
compact modular PC platform for test, measurement, and control systems.
Since PXI leverages the PCI bus, PXI users receive all the benefits of PCI
within an architecture that supports mechanical, electrical, and software
features tailored to industrial instrumentation, data acquisition, industrial
automation, and control 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.
1
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.
The NI PXI-8820 PXI/CompactPCI embedded computer is a
high-performance PXI/CompactPCI system controller. The NI PXI-8820
controller integrates standard I/O features in a single unit by using
state-of-the-art packaging. Combining an NI PXI-8820 embedded
controller with a PXI-compatible chassis, such as the NI PXI-1042, results
in a fully PC-compatible computer in a compact, rugged package.
The standard I/O on each module includes one DisplayPort video,
one RS-232 serial port, a parallel port, four high-speed USB 2.0 ports,
one Gigabit Ethernet connector, a reset button, and PXI triggers.
®
The NI PXI-8820 has a dual-core Intel
2 MB cache 2.2 GHz, Single Channel DDR3, 1333 MHz memory
controller, all the standard I/O, and an integrated hard drive.

Hard Drive Recovery
NI PXI-8820 controllers preinstalled with Windows include two methods
of restoring the original factory condition of your hard drive. Hard
drive-based recovery stores a factory backup on a separate portion of your
hard drive allowing you to restore your controller without additional media.
The NI PXI-8820 controller also ships with an OS Recovery CD that allows
you to reinstall your operating system onto your hard drive through an
external USB CD/DVD-ROM. For more information on these tools, refer
to KnowledgeBase 2ZKC02OK, Hard Drive Recovery and OS Installation for PXI and VXI Controllers, at
Note The hard drive recovery hot key is <F4>. To access the hard drive-based recovery
tool, press and hold <F4> when video first appears during the boot process.
If you want to recover your factory-installed operating system from a CD,
you can use the included OS re-installation CD with an external USB
CD/DVD-ROM drive. The re-installation CD does not reinstall the factory
OS image; it installs only a base operating system. Boot the PXI Express
controller using the OS re-installation CD to recover the OS. You also may
need to reinstall other software after using the CD to recover the OS.
Note Recovering the OS erases the contents of your hard disk, including the factory hard
drive recovery image. Back up the factory hard drive recovery image and any other files
you want to keep.
Installing an OS
NI PXI-8820 controllers may include a preinstalled OS. In some cases, you
may want to install a different OS. When doing so, consider the following
guidelines.
Installing from a USB CD/DVD-ROM
The NI PXI-8820 supports the installation of Windows 7 from a USB
CD/DVD-ROM. As an alternative to a USB CD/DVD-ROM drive, you can
use an external SCSI CD-ROM with a PXI-SCSI adapter.
Note For additional assistance with installing or changing an operating system, refer to
KnowledgeBase 2ZKC02OK, Hard Drive Recovery and OS Installation for PXI and VXI
Controllers, at
ni.com/support.
Power Budgeting
The NI PXI-8820 is a high power, high performance controller. It may
be necessary to perform power budgeting to ensure that the chassis
can adequately power all of the modules in the system. Refer to

Boot Options
What devices can I boot from?
The NI PXI-8820 can boot from the following devices:
•The internal Serial ATA hard drive
•An external SCSI hard drive or CD/DVD-ROM if an
SCSI adapter, such as the NI PXI-8214, is used
•An external USB mass storage device such as a USB hard drive,
USB CD/DVD-ROM, or USB key
•An external USB floppy drive
•Most PCI or PCIe-based devices that provide an Option ROM
Note There are some limitations when booting from a USB device. Windows 7
can be installed from a USB CD/DVD-ROM, but earlier versions of Windows cannot.
The NI PXI-8820 BIOS configures the USB devices so that they will work in a DOS
environment.
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 changing the boot order in the
BIOS, press <F10> continuously while booting. 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 PXI-8820 has no PS/2 connector, and you need to use a
USB Y-splitter cable as shown in Figure 4-1, or a similar device, to
connect both a PS/2 mouse and PS/2 keyboard. National Instruments part
number 778713-01 is such a cable and is available through the online

keyboard?
If you do not have a Y-splitter cable, plug a USB keyboard into any USB
connector. You can also plug a USB mouse into any USB connector.
How do I connect a standard 25-pin LPT cable to the NI PXI-8820?
The NI PXI-8820 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. Parallel
port adapter cables, part number 777169-01, are available through the
online catalog at
How do I connect a VGA monitor to the NI PXI-8820?
A DisplayPort-to-VGA adapter (part number 782271-01) is included with
your kit. You can use this adapter to connect a VGA monitor to a

How do I install software from a CD?
The compact size of the NI PXI-8820 does not allow for an integrated
CD/DVD-ROM drive. You have the following options:
•USB CD/DVD-ROM—You can install from a USB CD/DVD-ROM
using a bootable installation CD.
•SCSI CD-ROM—Other types of CD-ROM drives are available.
Check with the vendor to make sure Windows 7 supports the drive.
•Mapped network drive—You can use the Ethernet to connect to
another computer. If you share the USB CD/DVD-ROM drive on the
other computer, you can map the shared USB CD/DVD-ROM drive to
a drive letter on the NI PXI-8820.
A USB CD/DVD-ROM drive is available from National Instruments,
part number 778492-01.
You can change the amount of installed RAM on the NI PXI-8820 by
upgrading the SO-DIMM.
To upgrade the RAM, remove the NI PXI-8820 from the PXI chassis.
National Instruments offers the following types of SO-DIMMs for use with
the NI PXI-8820 controller.
•Replacement 2 GB RAM (NI part number 782911-2048)
•Replacement/upgrade 4 GB RAM (NI part number 782911-4096)
•Replacement/upgrade 8 GB RAM (NI part number 781736-8192)
Note National Instruments has conducted thermal testing as well as mechanical shock and
vibration testing, and has verified that the SO-DIMMs we sell work with the NI PXI-8820.
We recommend you purchase your SO-DIMM modules from National Instruments. Other
off-the-shelf SO-DIMM modules are not guaranteed to work properly.

This chapter answers common troubleshooting questions you may have
when using the NI PXI-8820 embedded computer.
What if the NI PXI-8820 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, and so on.)? 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?
•Refer to your chassis user manual for additional troubleshooting steps.
5
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 the controller in a different chassis.
•Try a similar controller in this same chassis.
•Clear the CMOS. (Refer to the System CMOS section of Chapter 2,
•Recover the hard drive on the controller. (Refer to the Hard Drive
Recovery section of Chapter 2, Installation and Configuration.)
•Make sure the RAM is properly seated.
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>.
You should now be able to reset the video driver to lower settings. Try
setting the resolution to 640 × 480 and the refresh rate to 60 Hz. 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.
Refer to the KnowledgeBase or product manuals section at
ni.com for
more information specific to the chassis and controller with which you are
having difficulties.
My CMOS is corrupted. How do I set it back to default?
1.Enter the BIOS setup program as described in the Accessing BIOS
Setup Utility 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.
As an alternative method, complete the following steps:
1.Power off the chassis.
