Introduction
Description and Features
MXI-Express x1 functions as a cabled PCI Express x1 link that enables
control of devices installed in a PXI, PXI Express, VXI, or CompactRIO
chassis through the use of desktop computers, workstations, laptops or
any other host controller with a PCI, PCI Express, or ExpressCard slot.
With MXI-Express x1, you can do the following:
• Control a PXI/PXI Express/CompactPCI/CompactPCI Express,
CompactRIO, or VXI backplane with a PCI, PCI Express, or
ExpressCard-based PC or laptop/mobile host adapter.
• Physically separate the measurement or automation system from
a host PC or laptop.
• Combine PCI Express, CompactPCI, CompactPCI Express, PXI,
PXI Express, and CompactRIO devices into the same system.
Table 1-1 lists the products covered by this manual, and lists their features

Chapter 1 Introduction
©National Instruments Corporation 1-3 MXI-Express x1 Series User Manual
Functional Overview
MXI-Express x1 is based on PCI Express technology. A MXI-Express x1
kit may use a combination of PCI Express switches or PCI Express-to-PCI
bridges to enable control of a PXI or PXI Express chassis from a PC with
an available PCI, PCI Express, or ExpressCard slot. The bridge architecture
is transparent to device drivers, so no additional software is needed for
CompactPCI level support for PXI or PXI Express devices in connected
chassis.
Note For full PXI/PXI Express functionality such as chassis and controller identification,
trigger routing, and slot detection, install the PXI Platform Services software included with
your kit. This software also can be found at ni.com/updates by searching for
PXI Platform Services.
The link between the PC and the chassis is a x1 cabled PCI Express link.
This link is a dual-simplex communication channel comprised of a
low-voltage, differentially driven signal pair. The link can transmit at a rate
of 2.5 Gbps in each direction simultaneously. This port is not compatible
with the cabled PCI Express specification developed by the PCI-SIG.
The BIOS of some host machines may not support the extension of the
PCI-Express fabric or PCI bus. Since this is the primary function of
MXI-Express x1 products, those systems may not boot or function
correctly. To address this issue, certain MXI-Express x1 products have
additional functionality intended to hide all PCI or PCI-Express resources
that are connected to the host machine, and allow NI MXI-Express BIOS
Compatibility Software to handle the enumeration process of these
resources instead of the BIOS.
In the cases where this software is required, there may be a dip switch on
the board that needs to be toggled as instructed by the documentation for
the software. The functional block diagrams in this chapter illustrate the
locations and availability of the dip switch package. Only the first dip
switch in the package is used for this purpose. The other switches serve no
function and should be left in their default position1.
1 On certain legacy MXI-Express x1 products that contain the dip switch package, the secondary switches may serve a reserved
purpose.

Chapter 1 Introduction
MXI-Express x1 Series User Manual 1-4 ni.com
Note Unless NI MXI-Express BIOS Compatibility Software is installed on the host
machine for use, the BIOS Compat Mode dip switch (switch 1) should remain in the off
position. If this mode is enabled on a MXI-Express x1 product in a host machine that does
not have the software installed, the connected devices will not be detected by the operating
system.
The ExpressCard-8360 (198266x-01L only) also includes support for
NI MXI-Express BIOS Compatibility Software, but the support is toggled
using the software instead of a physical dip switch. The software is required
to check whether the function is enabled.
For more information on host system compatibility with MXI-Express x1
products, refer to the NI Developer Zone document Tips to Help You
Successfully Use MXI-Express Controllers at ni.com/zone.

Basic MXI-Express x1 Systems
The simplest MXI-Express x1 system can consist of a host board1
connected to a target board1installed in the controller slot of a chassis or
integrated port of a chassis. Some example configurations are shown in
Figure 1-10, and Table 1-2 lists all connectivity options going from a host
PC to a chassis.
