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.

Chapter 2 Installation and Configuration
Connecting Safety Ground
Caution The PXI-1052 chassis is designed with a three-position NEMA 5-15 style plug
for the United States that connects the ground line to the chassis ground. To minimize
shock hazard, make sure the electrical power outlet you use to power the chassis has an
appropriate earth safety ground.
If the power outlet does not have an appropriate ground connection, you
must connect the premise safety ground to the chassis grounding screw
located on the rear panel. Refer to Figure 1-2, Rear View of the PXI-1052
Chassis, to locate the chassis grounding screw. Complete the following
steps to connect the safety ground.
1. Connect a 16 AWG (1.3 mm) wire to the chassis grounding screw
using a grounding lug. The wire must have green insulation with a
yellow stripe or must be noninsulated (bare).
2. Attach the opposite end of the wire to permanent earth ground using
toothed washers or a toothed lug.
Connecting to Power Source
Caution Do not install modules prior to performing the following power-on test.
Attach input power through the rear AC inlet using the appropriate
AC power cable supplied. Refer to Figure 1-2, Rear View of the PXI-1052
Chassis, to locate the AC inlet.
Caution To completely remove power, you must disconnect the AC power cable.
The power switch allows you to power on the chassis or place it in standby
mode. Push the power switch to the On (recessed) position (if not already
on). Observe that all fans become operational and the system power switch
LED is a steady green.
The system power indicator LED should be lit indicating that system power
is available to both the PXI and SCXI subsystems. The PXI subsystem
remains powered as long as the system power is on. However, you can
control the SCXI subsystem using the power switch on the rear panel.

Power Switch LED Indicators
The chassis has two LEDs next to the power switch. The system power
LED indicates the power status for the chassis. The SCXI power LED,
when lit, indicates that power is available to the SCXI subsystem. The
system power LED indicates one of three different conditions.
1. If the system power LED is steady green (not flashing), the chassis is
powered on and operating normally.
Caution Operating the PXI system outside of the specified temperature range can result in
loss of data, reduction of chassis life, or damage to equipment.
2. If the system power LED is flashing green, the air-intake temperature
has exceeded the chassis operating range. Complete the following
steps:
a. Power off the system.
b. Unplug the AC power cable.
c. Inspect the chassis for ventilation obstructions and clear them.
d. If the condition persists, contact NI using the information in the
front of this manual.
Chapter 2 Installation and Configuration
Caution Power supply output voltages out of regulation can result in equipment
malfunction, incorrect data, or failure of system to boot.
3. If the system power LED is flashing red, the PXI power supply
outputs are not within voltage regulation requirements. Complete
the following steps:
a. Power off the system.
b. Unplug the AC power cable.
c. Inspect the chassis for physical damage.
d. Verify that the there is no issue with the AC supply feed to the
PXI-1052 chassis.
e. If the condition persists, contact NI using the information in the
front of this manual.

Installing a PXI Controller
This section contains general instructions for installing a PXI controller in
the PXI-1052 chassis. Refer to your PXI controller user manual for specific
instructions and cautions. Complete the following steps to install a
controller.
1. Plug in the PXI chassis before installing the controller. The power cord
grounds the chassis and protects it from electrical damage while you
install the controller. Make sure the chassis power switch is in the Off
(Standby) position.
Caution To protect yourself and the chassis from electrical hazards, leave the chassis off
until you complete the controller installation.
2. Install the controller into the system controller slot (Slot 1, indicated
by the red card guides) by completing the following steps:
a. Place the controller edges into the front controller guides (top and
bottom).
b. Slide the controller to the rear of the chassis, making sure that the
injector/ejector handle is pushed down as shown in Figure 2-2.
