PXI-1045 Backplane Overview
Interoperability with CompactPCI
The PXI-1045 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-1045. Refer to
Appendix B, Pinouts, for pinout information.
The PXI-1045 has three PXI bus segments linked through two
32-bit/33 MHz PXI bridges. The PXI bus segment divisions are
represented on the front of the chassis by vertical lines as shown in
Figure 1-1.
Chapter 1 Getting Started
Note The PXI-1045 backplane is 32-bit PCI; 64-bit CompactPCI cards will operate in
32-bit mode in this chassis.
The PXI-1045 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. 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.
© National Instruments Corporation 1-5 NI PXI-1045 User Manual
Chapter 1 Getting Started
Star Trigger Slot
Peripheral Slots
Local Bus
The star trigger (ST) slot is slot 2. This slot has dedicated equal-length
trigger lines between slot 2 and peripheral slots 3 through 15 (refer to
Figure 1-3). The PXI Specification defines only 13 star trigger lines;
therefore, the last three slots do not receive a star trigger. 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 17 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 1-3). For example, slot 2’s right local bus connects to slot 3’s left
local bus, 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 18 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.

Trigger Bus
Note Although any trigger line may be routed in either direction, it cannot be routed in
more than one direction at a time.
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.
The PXI trigger lines from adjacent PXI trigger bus segments can be routed
in either direction across the PXI bridges through buffers. This allows you
to send trigger signals to, and receive trigger signals from, every slot in the
chassis. Static trigger routing (user-specified line and directional
assignments) can be configured through Measurement & Automation
Explorer (MAX). Dynamic routing of triggers (automatic line assignments)
is supported through certain National Instruments drivers like NI-DAQmx.
System Reference Clock
The PXI-1045 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 250 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 backplane’s 10 MHz source. You also can drive PXI_CLK10 from the
10 MHz REF IN BNC connector on the rear of the chassis (refer to
Figure 1-2). Sourcing an external clock on this connector automatically
overrides the backplane’s 10 MHz clock. If the clock signal is present on
both the PXI_CLK10_IN pin of the star trigger slot and the 10 MHz REF
IN connector on the rear of the chassis, the signal on the star trigger slot is
selected and provided to all peripheral slots and the external 10 MHz REF
OUT connector on the rear of the chassis.

Chassis Cooling Considerations
The PXI-1045 is designed to operate on a bench or in an instrument rack.
Determine how you want to use the PXI-1045 and follow the appropriate
installation instructions.
Providing Adequate Clearance
Apertures 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. Place the PXI-1045 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 have adequate
ventilation. Keep other equipment a minimum of 76.2 mm (3 in.) away
from the air inlets on the rear of the chassis.
When rack mounting the PXI-1045, provide at least 44.5 mm (1.75 in.)
clearance above and on the sides of the unit for adequate venting.
High-power applications may require additional clearance.
