PXI-1031/PXI-1031DC Backplane Overview

Interoperability with CompactPCI

The PXI-1031/PXI-1031DC backplane is interoperable with 5 V and
universal PXI-compatible products and standard CompactPCI products.
This is an important feature, because some PXI systems may require
components that do not implement PXI-specific features. For example,
you may want to use a standard CompactPCI network interface card in a
PXI chassis.

The signals on the backplane P1 connectors meet the requirements of the
CompactPCI specification for both peripheral and system modules. Refer
to Appendix B, Pinouts, for pinout information.

The PXI-specific signals are on the backplane P2 connectors and are
found only on those signal lines reserved or not used in the CompactPCI
64-bit specification. Therefore, all modules that meet the requirements
of the CompactPCI 64-bit specification will function in the
PXI-1031/PXI-1031DC. Refer to Appendix B, Pinouts, for pinout
information.

The chassis backplane has +5 V V(I/O). Refer to the CompactPCI
Specification PICMG 2.0 R 3.0 for details regarding V(I/O).

System Controller Slot

The system controller slot is slot 1 of the chassis as defined by the PXI
specification. It has three controller expansion slots for system controller
modules that are wider than one slot. As defined in the PXI specification,
these slots allow the controller to expand to the left to prevent the controller
from using peripheral slots.

NI PXI-1031/PXI-1031DC User Manual 1-6 ni.com

Star Trigger Slot

Peripheral Slots

Local Bus

Chapter 1 Getting Started

The star trigger (ST) slot is slot 2. This slot has dedicated equal-length
trigger lines between slot 2 and peripheral slots 3 and 4 (refer to
Figure 1-5). Slot 2 is intended for modules with ST functionality that can
provide individual triggers to all other peripheral modules. However, if you
do not require advanced trigger functionality, you can install any standard
peripheral module in this slot.

The star trigger slot can also be used to provide a PXI_CLK10 signal to
the backplane. For more information regarding PXI_CLK10, refer to the

System Reference Clock section.

There are three peripheral slots, including the star trigger slot.

The PXI backplane local bus is a daisy-chained bus that connects each
peripheral slot with adjacent peripheral slots to the left and right (refer to
Figure 1-5). For example, the right local bus of slot 2 connects to the left
local bus of slot 3, and so on.

The left local bus signal lines on slot 2 are used for star trigger and do not
connect to slot 1. The right local bus signal lines on slot 4 are not routed
anywhere.

Each local bus is 13 lines wide and can pass analog signals up to
42 V between cards or provide a high-speed TTL side-band digital
communication path that does not reduce the PXI bus bandwidth.

Initialization software uses the configuration information specific to
adjacent peripheral modules to evaluate local bus compatibility.

Local

Bus

Peripheral Slot [3]

Peripheral Slot [4]

All slots share eight PXI trigger lines. You can use these trigger lines
in a variety of ways. For example, you can use triggers to synchronize
the operation of several different PXI peripheral modules. In other
applications, one module located in slot 2 can control carefully timed
sequences of operations performed on other modules in the system.
Modules can pass triggers to one another, allowing precisely timed
responses to asynchronous external events the system is monitoring
or controlling.

System Reference Clock

The PXI-1031/PXI-1031DC supplies the PXI 10 MHz system clock signal
(PXI_CLK10) independently to each peripheral slot. An independent
buffer (having a source impedance matched to the backplane and a skew of
less than 1 ns between slots) drives the clock signal to each peripheral slot.
You can use this common reference clock signal to synchronize multiple
modules in a measurement or control system. You can drive PXI_CLK10
from an external source through the PXI_CLK10_IN pin on the
P2 connector of the star trigger slot. Refer to Table B-4, P2 (J2) Connector

Pinout for the Star Trigger Slot. You must manually switch SW1 on the

chassis backplane to enable or disable routing an external clock to
peripheral slots.

Chapter 2 Installation and Configuration

• Part Replacement—Only service this equipment with parts that are
exact replacements, both electrically and mechanically. Contact
National Instruments for replacement part information. Installation of
parts with those that are not direct replacements may cause harm to
personnel operating the chassis. Furthermore, damage or fire may
occur if replacement parts are unsuitable.

• Modification—Do not modify any part of the chassis from its original
condition. Unsuitable modifications may result in safety hazards.

Chassis Cooling Considerations

The chassis is designed to operate on a bench or in an instrument rack.
Determine how you want to use the chassis and follow the appropriate
installation instructions.

Providing Adequate Clearance

Apertures in the top, bottom, front, rear, and along the right side of the
chassis facilitate power supply and module cooling. Air enters through
filters and fan inlet in the bottom of the chassis for module cooling. It then
exits through the upper sections at the right side, back, and through the top,
as shown in Figure 2-1. Air cooling the power supply enters the front of the
chassis, which is shown in Figure 1-1, Front View of the PXI-1031 Chassis,
then exits through the rear of the chassis, which is shown in Figure 1-2,

Rear View of the PXI-1031 Chassis, and Figure 1-3, Rear View of the
PXI-1031DC Chassis. Place the chassis on a bench top or in an instrument

rack so that the fans (air inlets) and the air outlet apertures along the right
side, the top, and the back of the chassis have adequate ventilation. Provide
at least 44.5 mm (1.75 in.) clearance above, behind, and on the sides of the
unit for adequate venting. High-power applications may require additional
clearance.

Trigger Configuration in MAX

Each chassis has one or more trigger buses, each with eight lines numbered
0 through 7 that can be reserved and routed statically or dynamically. Static
reservation “pre-allocates” a trigger line to prevent its configuration by a
user program. Dynamic reservation/routing/deallocation is performed on
the fly within a user program based upon National Instruments APIs such
as NI-DAQmx. Static reservation of trigger lines can be implemented by
the user in MAX through the Triggers tab. Reserved trigger lines will not
be used by PXI modules dynamically configured by programs such as
NI-DAQmx. This prevents the instruments from double-driving the trigger
lines, possibly damaging devices in the chassis.

Chapter 2 Installation and Configuration

Using System Configuration and Initialization Files

The PXI specification allows many combinations of PXI chassis and
system modules. To assist system integrators, the manufacturers of PXI
chassis and system modules must document the capabilities of their
products. The minimum documentation requirements are contained in

.ini files, which consist of ASCII text. System integrators, configuration

utilities, and device drivers can use these

The capability documentation for the PXI-1031/PXI-1031DC chassis is

the system controller to create a single system initialization file called

pxisys.ini (PXI System Initialization). The system controller

manufacturer either provides a
model that contains the system controller or provides a utility that can
read an arbitrary

pxisys.ini file. System controllers from National Instruments use

MAX to generate the

pxisys.ini file for the particular chassis

chassis.ini file and generate the corresponding

pxisys.ini file from the chassis.ini file.

Device drivers and other utility software read the

pxisys.ini file to

obtain system information. Device drivers should have no need to directly

Maintenance

This chapter describes basic maintenance procedures you can perform on
the PXI-1031 and PXI-1031DC chassis.

Caution Disconnect the power cables prior to servicing the chassis.

DC Fuse Replacement (PXI-1031DC Only)

The PXI-1031DC is protected against over-current by a 30 A fuse on the
rear of the chassis, as shown in Figure 1-3, Rear View of the PXI-1031DC

Chassis. The fuse should only be replaced with a Wickmann 162.6385.530,

Littlefuse 257 030, or equivalent. To remove the fuse, pull straight out
from the chassis.

Service Interval

Clean the chassis fan filter at a maximum interval of six months.
Depending on the amount of use and ambient dust levels in the operating
environment, the filter may require more frequent cleaning.

3

Clean dust from the chassis exterior (and interior) as needed, based on the
operating environment. Periodic cleaning increases reliability.

Preparation

The information in this chapter is designed for use by qualified service
personnel. Read the Read Me First: Safety and Radio-Frequency
Interference document included with your kit before attempting any
procedures in this chapter.

Caution Many components within the chassis are susceptible to static discharge damage.

Service the chassis only in a static-free environment. Observe standard handling
precautions for static-sensitive devices while servicing the chassis. Always wear a
grounded wrist strap or equivalent while servicing the chassis.

Chapter 3 Maintenance

Cleaning

Caution Always disconnect the AC power cable (and the DC power cable, if you are

working with a PXI-1031DC chassis) before cleaning or servicing the chassis.

Interior Cleaning

Exterior Cleaning

Cautions Avoid getting moisture inside the chassis during exterior cleaning, especially

through the top vents. Use just enough moisture to dampen the cloth.

Do not wash the front- or rear-panel connectors or switches. Cover these components while
cleaning the chassis.

Cleaning procedures consist of exterior and interior cleaning of the chassis
and cleaning the fan filter. Refer to your module user documentation for
information on cleaning individual CompactPCI or PXI modules.

Use a dry, low-velocity stream of air to clean the interior of the chassis.
Use a soft-bristle brush for cleaning around components.

Do not use harsh chemical cleaning agents; they may damage the chassis. Avoid chemicals
that contain benzene, toluene, xylene, acetone, or similar solvents.

Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth moistened
with clear water. Do not use abrasive compounds on any part of the chassis.

Cleaning and Replacing the Fan Filter

A dirty fan filter can dramatically reduce the cooling performance of the
chassis. Clean the filter whenever it becomes visibly dirty. You can easily
remove the chassis air filter from the bottom of the chassis by removing the
filter cover. To remove the filter cover, loosen the retainer screw. The filter
cover is shown in Figure 1-4, Bottom View of PXI-1031/PXI-1031DC

Chassis.

NI PXI-1031/PXI-1031DC User Manual 3-2 ni.com

Chapter 3 Maintenance

Clean the fan filter by washing it in a mild soap solution and then
vacuuming or blowing air through it. Rinse the filter with water and allow
it to dry before reinstalling it on the chassis.

You can replace the fan filter with part number 150139-C from Air
Filtration Products, Inc., Tucson, AZ 85705, if necessary.

clock

A 10 MHz clock, also called PXI_CLK10, that is distributed to all
peripheral slots in the chassis, as well as a BNC connector on the rear of
chassis labeled 10 MHz REF OUT. The system reference clock can be used
for synchronization of multiple modules in a measurement or control
system. The 10 MHz REF IN and OUT BNC connectors on the rear of the
chassis can be used to synchronize multiple chassis to one reference clock.
The PXI backplane specification defines implementation guidelines for
PXI_CLK10.
