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.

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

Local Bus
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.
SCXI Control Slot
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.

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.

number accordingly in the white space.
Figure 2-6. Chassis Number Label
Trigger Configuration in MAX
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
chassis.
Complete the following steps to reserve these trigger lines in MAX.
1. In the Configuration tree, click the PXI chassis branch you want to
configure.
2. Click the Triggers tab at the bottom of the right-hand pane.

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 .ini files.
The capability documentation for the PXI-1052 chassis is contained in the
chassis.ini file on the software media that comes with the chassis. The
information in this file is combined with information about the system
controller to create a single system initialization file called pxisys.ini
(PXI System Initialization). The system controller manufacturer either
provides a pxisys.ini file for the particular chassis model that contains
the system controller or provides a utility that can read an arbitrary
chassis.ini file and generate the corresponding pxisys.ini file.
NI system controllers use MAX to generate the 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 not need to directly read
the chassis.ini file. For detailed information regarding initialization
SCXI Configuration with MAX

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.

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.
