PXI-1052 Backplane Overview

This section gives a basic hardware overview of the PXI-1052 backplane,
with interoperability information for the PXI-1052 with CompactPCI, and
general information about the local bus, including system controller slot,
the star trigger slot, and the peripheral slots.

© National Instruments Corporation 1-5 NI PXI-1052 User Manual

Chapter 1 Getting Started

Interoperability with CompactPCI

The PXI-1052 backplane is interoperable with 5 V and universal
PXI-compatible products and standard CompactPCI products. This is an
important feature because some PXI user systems can 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 function in the PXI-1052. Refer to
Appendix B, Pinouts, for pinout information.

The PXI-1052 backplane has +5 V V(I/O). Refer to the CompactPCI
Specification PICMG 2.0 R3.0 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. There are three controller expansion slots to the left of Slot 1
for system controller modules that are wider than one slot. This prevents
the controller from using peripheral slots.

Star Trigger Slot

Slot 2 is the star trigger slot. This slot has dedicated equal-length trigger
lines between Slot 2 and peripheral Slots 3 and 4 (refer to Figure 1-3).
Slot 2 is intended for modules with star trigger 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.

You also can use the star trigger slot to provide a PXI_CLK10 signal to
the backplane. For more information regarding PXI_CLK10, refer to the

System Reference Clock section.

Peripheral Slots

There are three peripheral slots including the star trigger slot.

NI PXI-1052 User Manual 1-6 ni.com

Local Bus

SCXI Control Slot

Chapter 1 Getting Started

The PXI backplane local bus is a daisy-chained bus that connects each
peripheral slot with adjacent peripheral slots to the left and right as shown
in Figure 1-3. For example, the Slot 2 right local bus connects to the Slot 3
left local bus, and so on.

The left local bus signal lines on Slot 2 are used for the star trigger and do
not connect to Slot 1. The right local bus signal lines on Slot 4 are used for
SCXI communication.

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.

Slot 4 of the PXI backplane has connections for a PXI peripheral module
such as an NI PXI DAQ module, an NI PXI DMM module, or an
NI-Switch controller module to control the SCXI subsystem. These
connections use the available local bus right pins (PXI_LBR0:12). The
SCXI connection passes communication, timing, and low-voltage analog
bus signals between the SCXI subsystem and the PXI module in Slot 4.

Note For more information about the local bus right pins, refer to the PXI Specification,

Revision 2.0.

Trigger Bus

All slots on each PXI bus segment 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.

Chapter 1 Getting Started

System Reference Clock

The PXI-1052 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 500 ps
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. Sourcing an external clock on this pin automatically overrides

the 10 MHz source of the backplane. Once the transition has been made,
reset the chassis to restore it to the initial state.

SCXI Subsystem Overview

To use the SCXI subsystem of the PXI-1052, you must have a
DAQ/DMM/Switch controller module in Slot 4 of the PXI subsystem
to control and/or acquire data from the SCXI modules.

Note The chassis address of the SCXI subsystem is hard-wired as 0.

Chassis Cooling Considerations

The PXI-1052 is designed to operate on a bench or in an instrument rack.
Determine how you want to use the PXI-1052 and follow the appropriate
installation instructions.

Providing Adequate Clearance

Openings in the top and along both sides of the chassis facilitate power
supply and module cooling. Air enters through filters and fan inlets in the
lower rear of the chassis and exits through the upper sections on both sides
and through the top, as shown in Figure 2-1. Provide adequate ventilation
space around the PXI-1052 on a bench top or in an instrument rack so that
the fans (air inlets) and the air outlet apertures along both sides and the top
of the chassis are not obstructed. Keep other equipment a minimum of

76.2 mm (3 in.) away from the air inlets on the rear of the chassis.

Each chassis has one or more trigger buses, each with eight lines numbered
0 through 7 that you can reserve and route statically or dynamically. Static
reservation pre-allocates a trigger line to prevent its configuration by a user
program. Dynamic reservation/routing/deallocation is automatic within a
user program based upon NI APIs such as NI-DAQmx. You can implement
static reservation of trigger lines in MAX through the Triggers tab.
Reserved trigger lines are not 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

Configure Channels and Tasks

A physical channel is a terminal or pin at which you can measure or
generate an analog or digital signal. A virtual channel is a collection of
settings that can include a name, a physical channel, input terminal
connections, the type of measurement or generation, and scaling
information. In Traditional NI-DAQ and earlier versions, configuring
virtual channels is an optional way to record which channels are used for
different measurements. In NI-DAQmx, virtual channels are integral to
every measurement.

NI PXI-1052 User Manual 2-16 ni.com

Chapter 2 Installation and Configuration

In Traditional NI-DAQ, you configure virtual channels using MAX. In
NI-DAQmx, you can configure virtual channels with the DAQ Assistant,
which you can open from MAX or your application software. You also can
configure virtual channels with the NI-DAQmx API in your application
program.

A task, an important new concept for NI-DAQmx, is a collection of one
or more virtual channels with timing, triggering, and other properties.
Conceptually, a task represents a measurement or generation you want to
perform. You can set up and save all of the configuration information in a
task and use the task in an application.

In NI-DAQmx, you can configure virtual channels as part of a task or
separate from a task. Virtual channels created inside a task are local

channels. Virtual channels defined outside a task are global channels. You

can create global channels in MAX or in your application software and then
save them in MAX. You can use global channels in any application or add
them to a number of different tasks. If you modify a global channel, the
change affects all tasks in which you reference that global channel. In most
cases, it is simpler to use local channels.
