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 Manual1-6ni.com
Star Trigger Slot
Peripheral Slots
Local Bus
Chapter 1Getting 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.
Figure 1-5. PXI Star Trigger and Local Bus Routing
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.

carefully read the following caution notices.
This equipment contains voltage hazardous to human life and safety, and is
capable of inflicting personal injury.
•Chassis Grounding—The chassis requires a connection from the
premise wire safety ground to the chassis ground. The earth safety
ground must be connected during use of this equipment to minimize
shock hazards. Refer to the Connecting Safety Ground section for
instructions on connecting safety ground.
•Live Circuits—Operating personnel and service personnel mustnot
remove protective covers when operating or servicing the chassis.
Adjustments and service to internal components must be undertaken
by qualified service technicians. During service of this product,
the mains connector to the premise wiring must be disconnected.
Dangerous voltages may be present under certain conditions;
use extreme caution.
•Explosive Atmosphere—Do not operate the chassis in conditions
where flammable gases are present. Under such conditions, this
equipment is unsafe and may ignite the gases or gas fumes.
•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.
