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 soware

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.

PCIe-8383 Manual

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.

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 soware for a system

that includes a PCIe-8383.

Note Refer to the NI Hardware and Soware 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 soware

specifications, and supplies system services to

other NI products.

Note You will need to install this

driver for full PXI/PXI Express

functionality such as chassis and

controller identification, trigger

routing, and slot detection.

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 oers MXI-Express

BIOS Compatibility soware. If you need to use this soware, you must toggle the

BIOS DIP switch on the board to enable BIOS compatibility.

Note Unless MXI-Express BIOS Compatibility soware 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 soware installed, the connected devices

will not be detected by the operating system.
