The PXI-1042 Series combines a high-performance 8-slot PXI backplane
with a high-output power supply and a structural design that has been
optimized for maximum usability in a wide range of applications. The
chassis’ modular design ensures a high level of maintainability, resulting in
a very low mean time to repair (MTTR). The PXI-1042 Series fully comply
with the PXI Specification, Revision 2.0, offering advanced timing and
synchronization features.
The key features of the PXI-1042 Series include the following:
• PXI and CompactPCI (PICMG 2.0 R 3.0) module compatibility
• Compact 3U-sized, 8-slot chassis
• Universal AC input: automatic voltage and frequency ranging
• Over-current protection through push-reset circuit breaker
(no AC-input fuses to replace)
• Removable modular power-supply shuttle
• Remote voltage monitoring and inhibit through a rear-panel connector
• On/Off (Standby) power switch on the front panel for easy access
• Temperature-sensing module that can adjust fan speed based on
air-intake temperature to minimize audible noise

Optional Equipment
Contact National Instruments to order the following options for the
PXI-1042 Series chassis.
EMC Filler Panels
Optional EMC filler panel kits are available from National Instruments.
Rack Mount Kits
Two rack mount kit options are available for mounting the PXI-1042 Series
chassis into a 19 in. instrument cabinet.
© National Instruments Corporation 1-5 NI PXI-1042 Series User Manual
Chapter 1 Getting Started
The first option is a pair of mounting brackets for use on the front of the
chassis. The second option is a rear rack mount kit. The rear rack mount kit
differs from the front kit to allow for easier installation into the rack.
For more information, refer to Figure A-3, PXI-1042 Series Chassis Rack
Mount Kit Components.
Slot Blockers
Optional slot blocker kits are available from National Instruments for
improved thermal performance when all slots are not used.
PXI-1042 Series Backplane Overview
Interoperability with CompactPCI
The PXI-1042 Series backplane is interoperable with 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 connector meet the requirements of the
CompactPCI specification for both the peripheral and system modules.
The PXI-specific signals are on the P2 connector and are found only on the
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-1042 Series.
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-1042 Series User Manual 1-6 ni.com
Star Trigger Slot
Peripheral Slots
Local Bus
Chapter 1 Getting Started
The Star Trigger (ST) slot is Slot 2. This slot has dedicated equal-length
trigger lines between Slot 2 and each remaining peripheral slot (refer to
Figure 1-4). This slot 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.
There are seven 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, as shown
in Figure 1-4.
The left local bus signals on Slot 2 are used for Star Trigger and do not
connect to Slot 1. The right local bus signals on Slot 8 are not routed
anywhere.
For example, a given peripheral slot’s right local bus connects to the
adjacent slot’s left local bus, and so on. Each local bus is 13 lines wide and
can pass analog signals between cards or provide a high-speed side-band
digital communication path that does not reduce the PXI bus bandwidth.
Local bus signals may range from high-speed TTL signals to analog signals
as high as 42 V.
Initialization software uses the configuration information specific to each
adjacent peripheral module to evaluate local bus compatibility.

PCI Arbitration and Clock Signals
All slots share eight 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
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-1042 Series chassis supply 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 replaces the backplane’s 10 MHz source. You also
can drive PXI_CLK10 from the 10 MHz REF IN connector on the rear of
the chassis. Sourcing an external clock on this connector automatically
NI PXI-1042 Series User Manual 1-8 ni.com
Chapter 1 Getting Started
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.

Installation and Configuration
This chapter describes how to prepare and operate the PXI-1042 Series
chassis.
Before connecting the chassis to a power source, read this chapter and the
Read Me First: Safety and Radio-Frequency Interference document
included with your kit.
Chassis Cooling Considerations
The PXI-1042 Series chassis are 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 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 chassis 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 3 in. away from the air
inlets on the rear of the chassis.
2
When rack mounting a PXI-1042 Series chassis, provide 1.75 in. (44.5 mm)
clearance above and on the sides of the unit for adequate venting.
High-power applications may require additional clearance.

Install the chassis so that you can easily access the rear panel. This
simplifies replacing the air filters or power supply shuttle assembly,
if necessary.
Setting Fan Speed
The fan-speed selector switch is on the rear panel of the PXI-1042 Series
chassis. Refer to Figure 1-2, Rear View of the PXI-1042 Chassis, and
Figure 1-3, Rear View of the PXI-1042Q Chassis, to locate the fan-speed
selector switch. Select HIGH for maximum cooling performance
(recommended) or AUTO for quieter operation. When set to AUTO,
the fan speed is determined by chassis intake air temperature.
Installing Filler Panels
To improve module cooling performance, install filler panels (provided
with the chassis) in unused or empty slots. Secure with the captive
mounting screws provided.
