Functional Overview

The NI PXIe-8383mc is a PXImc adapter1module that allows the attachment of sub-systems

such as stand-alone instruments, PCs, or other PXI-Express systems to an existing PXI-Express

system via a high-bandwidth, low-latency cabled MXI-Express x8 link2. The NI PXIe-8383mc

contains a PXImc Logic Block that makes it possible to join systems together non-transparently.

Figure 1 illustrates where the PXImc Logic Block is applied to join the Root Complexes of

two systems.

Figure 1. PXImc System Diagram

In the example shown, the system on the right is designated as a PXImc Device since it contains

the PXImc Logic block (i.e. the NI PXIe-8383mc). The system on the left is designated the

Primary System Host, which serves as the central connection hub for all other PXImc Devices.

1 Refer to Chapters 1 and 2 of 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.

This effectively creates a tree (or Star) connection topology as shown in the example

connectionscenario in Figure 2.

Figure 2. Example PXImc System

Figure 2 shows how various types of sub-systems can be connected to a Primary System Host to

create a tree topology of PXImc Devices. The cable ports of all PXImc Logic Blocks in the

example are indicated by an “mc” glyph to show their locations. In cases where a sub-system

does not contain a PXImc Logic Block, a NI PXIe-8383mc can be installed in the Primary

System Host to create a Logical PXImc Device out of the sub-system.

Tip Consolidating all NI PXIe-8383mc adapter modules into a single PXI-Express

chassis, ideally the Primary System Host, will simplify the power sequence of the

overall PXImc system.

Product Features

Figure 3 illustrates the core function and onboard features of the NI PXIe-8383mc.

Figure 3. NI PXIe-8383mc (153100x-02L) Block Diagram

The PXImc logic block consists of a non-transparent bridge and all the associated circuitry

necessary to work with clock references from both the Primary System Host and the PXImc

Device’s own sub-system. The non-transparent bridge (NTB) isolates the processor and

resources in the Primary System Host from those in the sub-system. The NTB is recognized as

a PCI Express system endpoint to each of the systems. As a result, devices and other PCI

resources on either side of the NTB are not visible to each other. Communication between the

two systems occurs through processor domain partitioning and address translation between the

memory-mapped spaces of the two processors.

Each side of the PXImc logic block is connected to the front panel “mc” cable port and

backplane connectors.

Tip For optimum link widths and performance, use the NI PXIe-8383mc in chassis

that support a Gen 2 x8 backplane link. The chassis should also be controlled by a

Slot 1 controller with Gen 2 x8 links to the backplane. National Instruments offers

Gen 2 PXI Express chassis and controllers that can establish x8 links.

Onboard Switches

The NI PXIe-8383mc contains the following onboard switches.

SW3—MC / DC Mode Switch

The NI PXIe-8383mc is a multi-personality product capable of operating in either

multi-computing (MC) mode or daisy-chain (DC) mode. This makes it possible for an

NI PXIe-8383mc in MC mode to connect to another NI PXIe-8383mc in DC mode, just as if it

were a NI PXIe-8384 daisy-chain module. National Instruments recommends operating the

NI PXIe-8383mc in MC mode, and using a NI PXIe-8384 for daisy-chain purposes.

SW4—FACT / USER (Factory / User) Mode Switch

The FACT/USER switch shown in Figure 3 selects between two different memory resource

request sizes. With the switch in the FACT position the NI PXIe-8383mc requests a minimal

amount of system resources and should be compatible with most computer systems that try to

connect to it. With the switch in the USER position the NI PXIe-8383mc requests a greater

amount of system resources which may affect system compatibility. Depending on your

application, USER mode may provide better system performance. Refer to the NI-PXImc Help

file included with the NI-PXImc driver for more information on this topic.

Note Some BIOSes may have trouble allocating the resources requested by the

NI PXIe-8383mc set to USER mode. The BIOSes of high performance NI embedded

controllers such as the NI PXIe-8133 and NI PXIe-8135 have been designed with this

in mind and offer maximum system compatibility.

MC / DC Mode Switch

SW3

MC (Default) PXImc Logic Block mode

DC Daisy-chaining mode*

* NI recommends using the NI PXIe-8384 instead of an NI PXIe-8383mc set to DC mode since

this feature may be removed in the future.

NI PXIe-8383mc Getting Started Guide |© National Instruments |7

This switch has no affect when SW3 is in DC mode.

SW5—CFC/SSC Clocking Mode Switch

When the board operates in daisy chain (DC) mode this switch determines the clocking mode

for the front panel cable port. NI recommends keeping this switch in the default SSC mode

unless otherwise specified. Regardless of the clock mode selected, the reference clock is

PCI Express Gen 2 specification compliant.

This switch has no affect when SW3 is in MC mode.

LED Indicators

The LEDs on the NI PXIe-8383mc give status information about power supplies, link state, and

mode of operation. Table 1 describes the function of the front panel LEDs.

There are also onboard LEDs that report more specific link status which can be useful for

debugging cases when the front panel PWR/LINK LED reports a solid amber status.

Link Good LEDs—LEDs that indicate a successful front panel cable link (LED FP) and

backplane link (LED BP) to the onboard PCIe NTB switch.

Link Activity LEDs—LED that indicates link activity on the backplane link (LED BP).

Refer to Figure 3 for the location of these LEDs.

Installation and Configuration

This section explains how to unpack and install the NI PXIe-8383mc hardware and software.

Unpacking

The NI PXIe-8383mc is shipped in antistatic packages to prevent electrostatic discharge (ESD)

to the devices. ESD can damage several components on the device.

Caution Never touch the exposed pins of connectors. Doing so may damage the

device.

To avoid such damage in handling the device, take the following precautions:

• Ground yourself using a grounding strap or by holding a grounded object.

• Touch the antistatic package to a metal part of the computer chassis before removing the

device from the package.

Remove the device from the package and inspect the device for loose components or any sign

of damage. Notify NI if the device appears damaged in any way. Do not install a damaged device

into the computer or into a PXI Express or CompactPCI Express chassis.

Store the device in the antistatic envelope when not in use.

Hardware Installation

The following are general instructions for installing the NI PXIe-8383mc. Consult your

computer user manual or technical reference manual for further instructions and warnings.

Caution The protection provided by the MXI-Express Gen II x8 products can be

impaired if it is used in a manner not described in this document.

Complete the following steps to install the NI PXIe-8383mc in your PXI Express or

CompactPCI Express chassis.

1. Power off your PXI Express or CompactPCI Express chassis, but leave it plugged in while

installing the NI PXIe-8383mc. The power cord grounds the chassis and protects it from

electrical damage while you install the module.

Caution To protect both yourself and the chassis from electrical hazards, leave the

chassis off until you finish installing the NI PXIe-8383mc.

2. Remove or open any doors or covers blocking access to the slot in which you intend to

install the NI PXIe-8383mc.

3. Touch a metal part of the chassis to discharge any static electricity that might be on your

clothes or body.

4. Make sure the injector/ejector handle is in its downward position. Be sure to remove all

connector packaging and protective caps from retaining screws on the module.

5. Identify which slot the NI PXIe-8383mc will be installed in the chassis. Refer to Table 2 to

determine which slot types the NI PXIe-8383mc is compatible with.

6. Align the NI PXIe-8383mc with the card guides on the top and bottom of the system

controller slot. Hold the handle as you slowly slide the module into the chassis until the

handle catches on the injector/ejector rail.

Caution Do not raise the injector/ejector handle as you insert the NI PXIe-8383mc.

It will not insert properly unless the handle is in its downward position so that it does

not interfere with the injector/ejector rail on the chassis.

7. Raise the injector/ejector handle until the module firmly seats into the backplane receptacle

connectors. The front panel of the NI PXIe-8383mc should be even with the front panel of

the chassis.

8. Tighten the bracket-retaining screws on the top and bottom of the front panel to secure the

NI PXIe-8383mc to the chassis.

9. Replace or close any doors or covers to the chassis.

Cabling

National Instruments offers a variety of shielded MXI-Express x8 copper cables that can be used

to connect the NI PXIe-8383mc to MXI-Express Gen 2 x8 products. The NI MXI-Express x8

copper cables use Molex x8 PCIe connectors, and have no polarity, so either end can be

connected to either product. For more information about these connectors visit Molex at

www.molex.com and search for x8 PCIe iPass.

Table 3 shows the various MXI-Express x8 copper cables available from National Instruments.

Caution Do not insert or remove the cable after either system is powered on. Doing

so can hang or cause errors in applications communicating with devices. If a cable

becomes unplugged, plug it back into the system. You will need to restart both

systems.

Powering On the PXImc System

The order that systems are powered on relative to each other is important to ensure proper

operation. BIOSes and operating systems make the assumption that all PCI devices in the entire

hierarchy will be available as soon as the boot sequence begins. In addition, the non-transparent

bridge in the PXImc Logic Block needs time to self-configure before the sub-system on the other

side of the cable link can connect to it.

Consolidating all NI PXIe-8383mc adapter modules into a single PXI-Express chassis, ideally

the Primary System Host, will simplify the power sequence of the overall PXImc system. Simply

power on the Primary System Host that contains all of the NI PXIe-8383mc adapter modules,

and then power on all of the sub-systems that are cabled to it.

For more complex PXImc System topologies, a simple approach to powering on all systems is

to perform the following steps.

1. Power on all systems and chassis and allow the operating systems to fully load.

2. Reboot all systems.
