Overview
The National Instruments PXI-PCI833x interface kits give PCs
direct control of PXI systems using MXI-4 technology. You can
also use NI PXI-8331 and NI PXI-8336 modules for linking
multiple PXI chassis. MXI-4 is a high-bandwidth link that is
transparent to software applications and drivers, therefore
providing the ability to use high performance desktop computers
or servers to control PXI systems.
Multichassis PXI Systems
MXI-4 can be used to connect multiple PXI chassis in a star or
daisy-chain configuration within a single system. To connect two
PXI chassis together with MXI-4, install a PXI-8331 (copper) or
PXI-8336 (fiber-optic) module into any peripheral slot of the
master chassis. Connect with the appropriate cable to a second
PXI-8331 or PXI-8336 in slot 1 of the slave chassis. For more
information on the possible star and daisy-chain topologies, please
see the
MXI-4 User Manual.
Hardware
PC Control of PXI
With a MXI-4 link, you can transparently control a PXI system
from any PCI slot, so high-performance desktop computers or
servers can control PXI systems. Because PXI is based on the
industry-standard PCI bus, MXI-4 provides a transparent link
where all PXI modules appear to the user as if they were PCI
boards within the computer itself. However, you benefit from the
increased number of slots, power and cooling per slot, module
selection, and synchronization features provided by PXI.
Additionally, with fiber-optic MXI-4 you can electrically isolate
your PXI measurement hardware from the PC with extended
length cabling up to 200 m.
The MXI-4 link consists of a PCI-8331 (copper) or PCI-8336
(fiber-optic) board in the PC, connected via the appropriate cable
to a PXI-8331 (copper) or PXI-8336 (fiber-optic) module in slot 1
of a PXI chassis. For convenience, you can purchase either a
complete MXI-4 kit with all necessary components, or purchase
the PCI board, PXI module, and cable separately.
MXI-4 Technology
MXI-4 operates as a PCI-to-PCI bridge that achieves software and
hardware transparency and high performance. MXI-4 builds on
the standard PCI-to-PCI bridge architecture by splitting the bridge
into two halves connected by a 1.5 Gb/s serial link. Additionally,
you can create multiple-chassis PXI systems using multiple MXI-4
links. The PCI specification allows up to 255 buses to be connected
in a system via PCI-PCI bridges such as MXI-4.
MXI-4 is an evolution of MXI-3. MXI-4 improves on MXI-3 by
supporting both 3.3 V and 5 V PCI signaling environments, error
checking and retransmission on the serial link for greater
reliability in electrically noisy or harsh environments, and
industrially rugged connectors.
