PCIe-8383 Manual
PCIe-8383 Overview
The PCIe-8383 is an MXI‑Express remote controller for devices or systems cabled
over PCI from a computer with a PCI Express slot. The remote controller provides a
x8 PCI Express link over a copper cable to the PXIe-8381 PXI Remote Control Module
when used for remote PXI system control. This link is transparent to soware
applications and drivers, helping you use industry‐standard desktop computers
and servers to control connected devices with no additional programming. With the
PCIe-8383, compatible PXI modules can be used as if they are PCI devices directly
installed in the computer.

MXI-Express Gen 2 x8 Overview
The PCIe-8383 is part of the MXI-Express Gen 2 x8 series pf products. MXI-Express
Gen 2 x8 extends PCI Express communication over a cable of up to 5 m. With
MXI-Express Gen 2 x8, you can do the following:
■Control a PXI Express or CompactPCI Express backplane with a PCI Express-
based PC.
■Physically separate the measurement or automation system from a host PC.
■Control multiple PXI Express or CompactPCI Express chassis with a single
PCI Express-based PC or PXI Express embedded controller.
MXI-Express Gen 2 x8 incorporates the latest technology to include:
■Support for PCI Express slots.
■Support for PXI Express and CompactPCI Express chassis.
■Improved error correction and handling for noisy or harsh environments.
■Improved mechanical connectivity.
■Improved performance.
MXI-Express Gen 2 x8 Products
The following table lists the products and their features for comparison.

Basic MXI-Express Gen 2 x8 Systems
The simplest MXI-Express Gen 2 x8 system consists of a PCIe-8383 in a PC connected
to a PXIe-8381 in the controller slot of a PXI Express chassis, as shown in the
following figure.
Note A CompactPCI Express chassis could be used instead of a PXI
Express chassis.

3. PXIe-8381
4. PXI Express Chassis
Larger MXI-Express Gen 2 x8 Systems
If multiple PCI Express slots are available in the host PC, additional PXI Express
chassis can be connected by installing an additional PCIe-8383 in any available Gen
2 x8 or wider PCI Express slot.
You can also daisy-chain from a PXI Express chassis that is already controlled by an
embedded controller, host PC, or laptop to additional PXI Express chassis using MXI-
Express Gen 2 x8 products. The figures below show how you can use MXI-Express
Gen 2 x8 cards to connect multiple PXI Express expansion chassis to a PC in a star or
daisy-chain topology.

PCIe-8383 Manual
The PCI specification allows up to 256 bus segments. MXI-Express Gen 2 x8 does not
limit this number, but the maximum number of bus segments allowed can be BIOS
or operating system dependent. Also, a computer may already have several PCI bus
segments internally, and the MXI-Express Gen 2 x8 link also has multiple PCI buses
internally. Every PCI Express device has at least one bus segment, though it will have
more if it includes a bridge or switch.

Components of a MXI-Express Gen 2 x8 System
The following list defines the minimum required hardware and soware for a system
that includes a PCIe-8383.
Note Refer to the NI Hardware and Soware Operating System
Compatibility page linked below for driver, desktop operating system, and
real-time operating system support for individual hardware devices.
Table 2. System Components
Component Description and Recommendations
Host PC The computer that houses the PCIe-8383.
Note Not all PCI Express expansion
slots that have x8 or wider physical
connectors are electrically capable
of x8 PCI Express operation. Check
with the motherboard manufacturer
to verify that the slot is capable of x8
PCI Express operation.
Expansion PXI Express or CompactPCI Express
Chassis
A chassis that houses and powers the
PXIe-8381.
Cables Connect the PXI Express board in the chassis to
the PCIe-8383 in your computer.
PXI Remote Control Module Your PCIe-8383.
PXI Express Controller The PXIe-8381, which allows you to control PXI
and CompactPCI systems from your computer
using a fully transparent MXI-Express link.
PXI Platform Services Driver Provides support for NI PXI chassis and
controllers, implements PXI soware
specifications, and supplies system services to
other NI products.

Compatibility with Host PCs
The BIOS of some host PCs may not support the extension of the PCI-Express fabric.
Since this is the primary function of MXI-Express Gen 2 x8 products, those systems
may not boot or function correctly. To help address this issue, NI oers MXI-Express
BIOS Compatibility soware. If you need to use this soware, you must toggle the
BIOS DIP switch on the board to enable BIOS compatibility.
Note Unless MXI-Express BIOS Compatibility soware is installed on the
host PC, the BIOS DIP switch should remain in the disabled (default)
position. If this mode is enabled on a MXI-Express Gen 2 x8 product in a
host PC that does not have the soware installed, the connected devices
will not be detected by the operating system.
