This chapter provides overview information for PXI Express and the
NI PXIe-8101/8102 embedded controller.
Benefits of PXI Express
The PXI (PCI eXtensions for Instrumentation) industry standard, an open
specification governed by the PXI Systems Alliance (PXISA), has quickly
gained adoption and grown in prevalence in test, measurement, and control
systems since its release in 1998. One of the key elements driving the rapid
adoption of PXI is its use of PCI in the communication backplane. As
the commercial PC industry has improved the available bus bandwidth
by evolving PCI to PCI Express, PXI is now able to meet even more
application needs by integrating PCI Express into the PXI standard. By
taking advantage of PCI Express technology in the backplane, PXI Express
increases the maximum PXI bandwidth from up to 132 MB/s to up to
6 GB/s for a more than 45x improvement in bandwidth.
PXI Express maximizes both hardware and software compatibility with
PXI modules. PXI Express hybrid slots deliver both PCI and PCI Express
signaling to accept devices that use PXI communication and triggering or
the newer PXI Express standard. Software compatibility is maintained
because PCI Express uses the same OS and driver model as PCI, resulting
in complete software compatibility among PCI-based systems, for example
PXI, and PCI Express-based systems such as PXI Express.
1
PXI Express, like PXI, leverages from the CompactPCI specification to
define a rugged, modular form factor that offers superior mechanical
integrity and easy installation and removal of hardware components.
PXI Express products offer higher and more carefully defined levels of
environmental performance required by the shock, vibration, temperature,
and humidity extremes of industrial environments. Mandatory
environmental testing and active cooling is added to the CompactPCI
mechanical specification to ease system integration and ensure multivendor
interoperability.
The demanding timing and synchronization requirements of
instrumentation systems are met by the integrated features of PXI Express.
Not only are the trigger bus, 10 MHz system reference clock, and star
trigger bus available in PXI retained by PXI Express, but new timing and
synchronization features that include a 100 MHz differential system
reference clock for the synchronization of multiple modules and three
differential star trigger buses for the distribution of precise clock and trigger
signals have been added. Differential timing and synchronization signals
provide PXI Express systems with increased noise immunity and the ability
to transmit clock signals at higher frequencies.

can use this setting to disable AHCI mode so that non-compatible
OSes function correctly. The default value is AHCI.
•Serial ATA Port 0—This item displays the onboard SATA drive
detected in the system.
CPU Configuration Submenu (NI PXIe-8102 Only)
Use this submenu to apply alternate settings to the CPU. Normally, you do
not need to modify these settings, as the factory default settings provide the
most compatible and optimal configuration possible.
•Core Multi-Processing Controller—This setting specifies whether
or not the second core of the processor is enabled or disabled. The
default value is Enabled.
•Processor Type, Speed, and Number of Cores—These values
indicate the type of processor used in the NI PXIe-8101/8102
controller, the speed of the processor, and the number of processor
cores.
Video Configuration Submenu
Use this submenu to apply alternate settings to the video configuration.
Normally, you do not need to modify these settings, as the factory default
settings provide the most compatible and optimal configuration possible.
•Primary Display—This setting specifies which video adapter the
BIOS should use as the primary adapter if more than one is present.
To use an external video adapter as the primary graphics adapter,
choose Add-in PCI Video. The default value is Onboard Video.
•Total Graphics Memory—This setting specifies the amount of
system memory to allocate as graphics memory for use by the onboard
video device. The default value is 256 MB.
•DDC Routing—This setting determines how the monitor DDC is
routed. Use this setting to select whether or not the DDC is routed for
an analog monitor or a DVI monitor. In order to use a DVI monitor, this
setting must be set to DVI. An analog monitor, however, will function
with this option set to either Analog or DVI. The DDC communication
path is only enabled when set to Analog for an analog monitor, so
certain advanced features of your analog monitor may only be enabled
when routing DDC to Analog. The default setting is DVI.
PCI Express Configuration Submenu
Use this submenu to apply alternate settings to the PCI Express
configuration. Normally, you do not need to modify these settings,
as the factory default settings provide the most compatible and optimal
configuration possible.
•PCIe High Priority Port—This setting specifies whether or not one
of the PCI Express ports will receive priority when arbitrating data
bandwidth. The default value for this setting is Disabled.
•Select Port—This setting determines which port receives priority
when arbitrating data bandwidth if the PCIe High Priority Port
setting is Enabled. To give priority to one of the four ports routed to a
PXIe chassis, select Root Port [1-4]. The default value for this setting
is Root Port 1.
Use this submenu to apply alternate settings to the power and reset
configuration. Normally, you do not need to modify these settings,
as the factory default settings provide the most compatible and optimal
configuration possible.
•Restore on AC Power Loss—This setting specifies how the controller
should behave after an AC power loss event occurs. The controller can
be configured to Stay Off or Turn On. The default is Stay Off.
•Resume on PCIe WAKE#—This setting determines whether the
system can wake from Hibernate via the PCI Express WAKE# signal.
This feature must be enabled to wake the system from a device in a
PXI Express slot. The default value for this setting is Disabled.
•Power Button Off Behavior—This setting specifies the system
behavior after pressing the power button when the system is in a
running state. Normal allows the operating system to control the
power off behavior. Force Off causes an immediate system shutdown. Disable completely disables the power button. The default value for
this setting is Normal.
Caution Setting Power Button Off Behavior to Disabled is intended for advanced use
only when the system power will be controlled through an alternate mechanism. For
example, when the PXIe Chassis Inhibit Switch is set to Manual, the Inhibit signal can
control the system power instead. Refer to an appropriate PXIe chassis User Manual for
more information on these options. Setting Power Button Off Behavior to Disabled
under other circumstances may result in situations where the system can only power down
safely by disconnecting AC power directly.
USB Configuration Submenu
Use this submenu to apply alternate configurations to the USB ports.
Normally, you do not need to modify these settings, as the factory default
settings provide the most compatible and optimal configuration possible.
•USB Devices—This item lists the total number of devices detected in
the system, categorized by device type.
•Legacy USB Support—This setting specifies whether or not legacy
USB support is enabled. Legacy USB support refers to the ability to
use a USB keyboard and mouse during system boot or in a legacy
operating system such as DOS. The default value is Enabled.
