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.
NI PXI-1042 Series User Manual 2-2 ni.com
Installing Slot Blockers
The cooling performance of the chassis can be improved by installing
optional slot blockers. Refer to
Rack Mounting

a steady green.
Caution To remove power, you must disconnect the AC power cable.
Installing a PXI Controller
This section contains general installation instructions for installing a PXI
controller in a PXI-1042 Series chassis. Refer to your PXI controller user
manual for specific instructions and warnings. To install a controller,
complete the following steps:
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 power switch is in the Off
(standby) position.
Caution To protect both yourself and the chassis from electrical hazards, leave the chassis
off until you finish installing the controller.
2. Install the controller into the system controller slot (red card guides) by
first placing the controller edges into the front controller guides (top
and bottom). 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).

Power Switch LED Indicator
The chassis power switch has an integrated LED. This LED indicates one
of three different conditions:
• If the power switch LED is steady green (not flashing), the chassis is
powered on and operating normally.
• If the power switch LED is flashing green, the air-intake temperature
has exceeded the chassis operating range.
• If the power switch LED is flashing red, the power supply outputs are
not within voltage regulation requirements.
Remote Voltage Monitoring and Control
The PXI-1042 Series chassis support remote voltage monitoring and
inhibiting through a male 9-pin D-SUB (DB-9) connector located on the
rear panel. Table 2-1 shows the pinout of the 9-pin D-SUB (DB-9)
connector.

Chapter 2 Installation and Configuration
You can use the Inhibit signal (active low) to power off the chassis. To
remotely power off the chassis, connect the Inhibit pin (pin 5) to a Logic
Ground pin (pin 1 or 9). As long as this connection exists, the chassis will
remain off (standby); when you remove this connection, the chassis
turns on.
Note For the Inhibit signal to control the On/Off (standby) state of the chassis, the front
power switch must be in the On (recessed) position.
Caution When connecting digital voltmeter probes to the rear 9-pin D-SUB (DB-9)
connector, be careful not to short the probe leads together. Doing so could damage the
power supply.
You can use a digital voltmeter to ensure all voltage levels in the PXI-1042
Series are within the allowable limits. Referring to Table 2-2, connect one
lead of the voltmeter to a supply pin on the remote voltage monitoring
connector (9-pin D-SUB) on the rear panel. Refer to Table 2-1 for a pinout
diagram of the remote voltage monitoring connector. Connect the reference
lead of the voltmeter to one of the ground pins. Compare each voltage
reading to the values listed in Table 2-2.
Note Use the rear-panel 9-pin D-SUB connector to check voltages only. Do not use the
connector to supply power to external devices.

Chapter 2 Installation and Configuration
PXI_CLK10 Rear Connectors
There are two BNC connectors on the rear of the PXI-1042 Series chassis
for PXI_CLK10. The connectors are labeled IN and OUT. You can use
them for supplying the backplane with PXI_CLK10 or routing the
backplane’s PXI_CLK10 to another chassis.
10 MHz REF IN
You can use the 10 MHz REF IN connector to supply an external 10 MHz
clock to the backplane. The external clock signal is buffered and provided
to each peripheral slot’s PXI_CLK10 pin with a maximum slot-to-slot
skew of 250 ps. When the backplane detects a 10 MHz signal on the
10 MHz REF IN connector, it automatically overrides the 10 MHz clock
provided by the backplane and uses the externally provided clock. If the
backplane detects a 10 MHz clock on the PXI_CLK10_IN pin of Slot 2 and
a 10 MHz clock on the external 10 MHz REF IN connector, the backplane
automatically selects the signal from Slot 2 and provides that signal to each
peripheral slot.
The input impedance of the 10 MHz REF IN connector on the rear of the
chassis is 50 Ω ±5Ω. The backplane accepts a 10 MHz clock signal
between 200 mV
PXI_CLK10 IN signal. The input signal may be a 10 MHz square wave
or sine wave.
and 5 Vpp and rejects any DC component of the
pp
10 MHz REF OUT
The 10 MHz REF OUT connector provides a buffered non-TTL version
of the PXI_CLK10 TTL signal supplied to the peripheral slots on the
backplane. You can use this signal to synchronize multiple PXI chassis
to the same PXI_CLK10 signal.
The output impedance of this connector is 50 Ω ±5Ω. The output signal is
a 1 V
±20% non-TTL square wave.

Chapter 2 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
The capability documentation for the PXI-1042 Series 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
pxisys.ini file. System controllers from NI provide the pxisys.ini
chassis.ini file and generate the corresponding
file for the PXI-1042 Series chassis, so you should not need to use the
chassis.ini file. Refer to the documentation provided with the system
controller or to
and
chassis.ini files.
ni.com/support for more information on pxisys.ini
.ini files.
Device drivers and other utility software read the
pxisys.ini file to
obtain system information. The device drivers should have no need to
directly read the
initialization files, refer to the PXI specification at

System controller A module configured for installation in Slot 1of a PXI chassis. This device
is unique in the PXI system in that it performs the system controller
functions, including clock sourcing and arbitration for data transfers across
the backplane. Installing such a device into any other slot can damage the
device, the PXI backplane, or both.
system reference
clock
A 10 MHz clock, also called PXI_CLK10, that is distributed to all
peripheral slots in the chassis, as well as a BNC connector on the rear of
chassis labeled 10 MHz REF OUT. The system reference clock can be used
for synchronization of multiple modules in a measurement or control
system. The 10 MHz REF IN and OUT BNC connectors on the rear of the
chassis can be used to synchronize multiple chassis to one reference clock.
The PXI backplane specification defines implementation guidelines for
PXI_CLK10.
