PXI Express Features
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 available PXI bandwidth from up to 132 MB/s to up to 8 GB/s for a
more than 60x 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.

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.
NI PXIe-8830mc Overview
Functional Overview
The NI PXIe-8830mc is a PXImc device1 module that allows the attachment of subsystems
such as standalone instruments, PCs, or other PXI Express systems to an existing PXI Express
system via a high-bandwidth, low-latency PXI Express backplane Gen2 x8 link. The NI
PXIe-8830mc contains a PXImc logic block that makes it possible to join systems together
nontransparently.
The following figure illustrates where the PXImc logic block is applied to join the root
complexes of two systems.
1Refer to the PXI-7 PXI MultiComputing Hardware Specification Revision 1.0, available on the
pxisa.org website, for relevant terminology and concepts used in this guide.

In this example, the system on the right is designated as a PXImc device because it contains
the PXImc logic block (that is, the NI PXIe-8830mc). The system on the left is designated the
primary system host, which serves as the central connection hub for all other PXImc devices.

The NI PXIe-8830mc consists of the following logic blocks on one circuit card assembly
(CCA):
• The processor is an Intel® Core™ i7 4700EQ processor (6 MB Cache, 2.3 GHz). The
processor connects to the SO-DIMM block through the DDR3L interface supporting up
to 1600 MHz SO-DIMMs, the PCH through a x4 DMI2 (Direct Media Interface)
interface supporting up to 5 GT/s per lane.
• The SO-DIMM block consists of one 64-bit DDR3L SDRAM socket that can hold up to
8 GB of memory.
• The Platform Controller Hub (PCH) provides the USB, PCI Express x1, and LPC
interfaces that connect to the peripherals on the NI PXIe-8830mc.
• The USB block consists of two Hi-Speed USB 2.0 connectors.
• The Ethernet Port block consists of an Intel® I217-LM Gigabit Ethernet Connection.
• The Watchdog block consists of a watchdog timer that can reset the processor module or
generate triggers.
• The PXI Express Connectors connect the NI PXIe-8830mc to the PXI Express/
CompactPCI Express backplane.
National Instruments Software
National Instruments has developed several software tools you can use with the
NI PXIe-8830mc.
National Instruments’ hardware and software work together to help you make the most of your
PXI Express system. The LabVIEW, Measurement Studio, and LabWindows™/CVI™
