Installing the NI PXI-8840 Quad-Core into a PXI
Chassis
To install the NI PXI-8840 Quad-Core into a PXI chassis, complete the following steps.
1. Plug in your chassis before installing the NI PXI-8840 Quad-Core. The power cord
grounds the chassis and protects it from electrical damage while you install the module.
Caution In some National Instruments chassis, such as the NI PXI-1042, you
must ensure that the power LED is off. For more information about chassis
power behavior, refer to the user manual for the specific chassis.
Caution To protect both yourself and the chassis from electrical hazards,
leave the chassis off until you finish installing the NI PXI-8840 Quad-Core.
2. Remove any panels blocking access to the system controller slot (Slot 1) in the chassis.
3. Touch the metal part of the chassis case to discharge any static electricity that might be on
your clothes or body.
4. Remove the protective plastic covers from the four bracket-retaining screws as shown in
the following figure.
Figure 1. Removing Protective Plastic Covers

1. Protective Screw Cap (4x)
5. Make sure the injector/ejector handle is in its downward position. Align the NI PXI-8840
Quad-Core 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 PXI-8840 Quad-Core. The module will not insert properly unless the handle

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
is in its downward position so that it does not interfere with the injector rail on
the chassis.
6. Hold the handle as you slowly slide the module into the chassis until the handle catches
on the injector/ejector rail.
7. Raise the injector/ejector handle until the module firmly seats into the backplane
receptacle connectors. The front panel of the NI PXI-8840 Quad-Core should be even
with the front panel of the chassis.
8. Tighten the four bracket-retaining screws on the top and bottom of the front panel to
secure the NI PXI-8840 Quad-Core to the chassis.
9. Check the installation.
10. Connect the keyboard and mouse to the appropriate connectors. If you are using a PS/2
keyboard and a PS/2 mouse, a Y-splitter adapter is available to connect both to a single
USB connector. National Instruments offers a Y-splitter adapter cable, part number
778713-02, available through the online catalog at ni.com/products.
11. Connect the DisplayPort monitor video cable to the DisplayPort connector, or use the
DisplayPort-to-VGA adapter included with your controller to connect a VGA monitor to
the DisplayPort connector.
12. Connect devices to ports as required by your system configuration.
13. Power on the display. Refer to the NI PXI-8840 Quad-Core User Manual for details.
14. Power on the chassis.
15. Verify that the controller boots. If it does not boot, refer to the Troubleshooting section.
The following figure shows an NI PXI-8840 Quad-Core controller installed in the system
controller slot of an NI PXI-1042 chassis.

LabVIEW RT
This section explains software installation and switch configuration for LabVIEW RT on your
PXI controller.
LabVIEW RT Software Installation
The following section describes the necessary steps to get your PXI embedded controller set
up to run LabVIEW Real-Time. In this section you will configure the controller boot mode,
verify or change IP settings, and install LabVIEW Real-Time software.
Complete the following steps to install the LabVIEW RT software.
1. Boot the NI PXI embedded controller into the real-time operating system. Refer to the
LabVIEW RT Configuration Switches section or the LabVIEW RT Setup Menu section in
this document to configure the controller for booting into LabVIEW RT. The PXI
controller automatically boots into LabVIEW RT Safe Mode when no software is
installed. LabVIEW RT Safe Mode loads with the basic real-time operating system and
automatically attempts to connect to the network using DHCP. If DHCP is not available,
it then connects to the network with a link-local IP address.
Tip You can connect a monitor to the desktop PC to display startup messages
such as the IP address.
2. Open Measurement & Automation Explorer (MAX) on another computer in the same
subnet and expand the Remote Systems branch. MAX lists the PXI controller as the
controller model name followed by the MAC address (for example, NI-PXI-8840
00802f108562).
Note The other computer must have LabVIEW, LabVIEW RT, and any
desired drivers installed.
Tip Record the PXI controller MAC address, located on the side of the
controller, for use in identifying the controller. You also can remove the label
and place it on the front of the controller for easier access.
3. Click the appropriate PXI controller entry to access the Network Settings tab in the right
pane view.
4. (Optional) Enter a name for the RT target in the Name text box.
5. (Optional) Set the network configuration options of the RT target in the IP Settings
section and click the Apply button. For information about configuring network settings,
refer to the Configuring Network Settings book, accessible by browsing to MAX Remote
Systems Help»LabVIEW Real-Time Target Configuration»Configuring Network
Settings from the Contents tab of MAX Help.
Note When any IP or identification settings are changed, you are prompted to
reboot the controller for the changes to take effect. Click Yes to reboot the RT

target automatically. You may also reboot the controller by right-clicking the
target name under Remote Systems and selecting Reboot.
After rebooting the PXI controller, it appears in the Remote Systems category with the
assigned name.
6. Expand the PXI controller view in the Remote Systems branch and select Software.
7. Click the Add/Remove Software button in the toolbar to launch the LabVIEW Real-
Time Software Wizard.
8. Install the LabVIEW Real-Time software and device drivers that you require on the RT
target. Refer to the NI Web site at ni.com/info and enter the Info Code etspc for the
latest information about supported software.
After software installation, the controller automatically reboots, and you now can program it
using LabVIEW Real-Time.
Note Refer to the RT Getting Started Guide on your host computer for more
information about setting up your RT target.
LabVIEW RT Configuration Switches
Use the LabVIEW RT configuration switches to configure LabVIEW RT if it is installed on
the controller. If you are not using LabVIEW RT, these switches should remain in the OFF
position. The controller reads these switches only after a system reset.
The NI PXI-8840 Quad-Core controller includes the following LabVIEW RT configuration
switches:
• Switch 1—Boot LabVIEW RT: Set this switch to ON to boot LabVIEW RT.
• Switch 2—Boot Safe Mode: Set this switch to ON to boot LabVIEW RT into safe mode
to reconfigure TCP/IP settings and to download or update software from a host computer.
This switch overrides the behavior of Switch 1. Booting the controller into safe mode
does not start the embedded LabVIEW RT engine. After changing the settings or
software, reboot the controller with this switch OFF to resume normal operation.
• Switch 3—Disable Startup VI: Set this switch to ON to prevent VIs from automatically
running at startup if the controller becomes inaccessible because of a startup VI.
• Switch 4—Reset IP Address: Set this switch to ON to reset the IP address and other
TCP/IP settings to their factory defaults. Use this switch if moving the controller to a
different subnet or if the current TCP/IP settings are valid.
Note By default, the target automatically attempts to connect to the network using
DHCP. If the target cannot initiate a DHCP connection, the target connects to the
network with a link-local IP address or 169.254.x.x.
The following figure shows the location of the LabVIEW RT configuration switches. The
switches are shown in the OFF position.

Drivers and Software
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 are drivers and NIDRIVERS directories. The drivers directory
contains driver installers for the system peripherals. These files and directories are copied
exactly from the manufacturer distribution disks, so the naming conventions vary from
peripheral to peripheral. The NIDRIVERS directory contains the GPIB and PXI Platform
Services drivers preinstalled on the controller.
Data Storage
The NI PXI-8840 Quad-Core has the following data storage features:
• 2.5 in. SATA notebook internal hard drive
• USB storage support—USB CD/DVD-ROM, mass storage device, or floppy drive
