System Controller Slot
The system controller slot is Slot 1 of the chassis and is a 4-Link
configuration system slot as defined by the CompactPCI Express and
PXI Express specifications. It has three system controller expansion slots
for system controller modules that are wider than one slot. These slots
allow the system controller to expand to the left to prevent the system
controller from using peripheral slots.
The backplane routes each of the system slots’ x4 PCI Express (PCIe) links
to a PCIe switch. The four (4) PCIe switches have x4 PCIe links routed to
each peripheral slot as well as x1 links to two (2) PCIe-to-PCI bridges
providing 32-bit/33 MHz PCI busses to the hybrid slots. Refer to
Figure 1-3 for the connectivity of PCIe and PCI.
By default, the system controller will control the power supply with the
PS_ON# signals. A logic low on this line will turn the power supply on.
Note The Inhibit Mode switch on the rear of the chassis must be in the Default position
for the system controller to have control of the power supply. Refer to the Inhibit Mode
Switch section of Chapter 2, Installation and Configuration, for details about the Inhibit
Mode switch.
Chapter 1 Getting Started
Hybrid Peripheral Slots
The chassis provides eight hybrid peripheral slots as defined by the PXI-5
PXI Express Hardware Specification: slots 2–5 and slots 15–18. A hybrid
peripheral slot can accept the following peripheral modules:
• A PXI Express Peripheral with x4 or x1 PCI Express link to the system
slot or through a PCIe switch to the system slot.
• A CompactPCI Express Type-2 Peripheral with x4 or x1 PCI Express
link to the system slot or through a PCIe switch to the system slot.
• A hybrid-compatible PXI Peripheral module that has been modified by
replacing the J2 connector with an XJ4 connector installed in the upper
eight rows of J2. Refer to the PXI Express Specification for details. The
PXI Peripheral communicates through the backplane’s 32-bit PCI bus.
• A CompactPCI 32-bit peripheral on the backplane’s 32-bit PCI bus.
The hybrid peripheral slots provide full PXI Express functionality and
32-bit PXI functionality except for PXI Local Bus. The hybrid peripheral
slot only connects to PXI Local Bus 6 left and right.
© National Instruments Corporation 1-7 NI PXIe-1075 User Manual
Chapter 1 Getting Started
PXI Express Peripheral Slots
There are eight (8) PXI Express peripheral slots: slots 6–9 and 11–14
(=8 slots). PXI Express peripheral slots can accept the following modules:
• A PXI Express Peripheral with x4 or x1 PCI Express link to the system
slot or through a PCIe switch to the system slot.
• A CompactPCI Express Type-2 Peripheral with x4 or x1 PCI Express
link to the system slot or through a PCIe switch to the system slot.
System Timing Slot
The System Timing Slot is slot 10. The system timing slot will accept the
following peripheral modules:
• A PXI Express System Timing Module with x4 or x1 PCI Express link
to the system slot through a PCIe switch.
• A PXI Express Peripheral with x4 or x1 PCI Express link to the system
slot through a PCIe switch.
• A CompactPCI Express Type-2 Peripheral with x4 or x1 PCI Express
link to the system slot through a PCIe switch.
The system timing slot has 3 dedicated differential pairs (PXIe_DSTAR)
connected from the TP1 and TP2 connectors to the XP3 connector for each
PXI Express peripheral or hybrid peripheral slot, as well as routed back to
the XP3 connector of the system timing slot as shown in Figure 1-4. The
PXIe_DSTAR pairs can be used for high-speed triggering, synchronization
and clocking. Refer to the PXI Express Specification for details.
The system timing slot also has a single-ended (PXI Star) trigger connected
to every slot. Refer to Figure 1-4 for details.
The system timing slot has a pin (PXI_CLK10_IN) through which a system
timing module may source a 10MHz clock to which the backplane will
phase-lock. Refer to the System Reference Clock section for details.
The system timing slot has a pin (PXIe_SYNC_CTRL) through which a
system timing module can control the PXIe_SYNC100 timing. Refer to the
PXI Express Specification and the PXIe_SYNC_CTRL section of this
chapter for details.

The PXI backplane local bus is a daisy-chained bus that connects each
peripheral slot with adjacent peripheral slots to the left and right.
PXIe_DStar 14
PXIe_DStar 15
The backplane routes PXI Local Bus 6 between adjacent PXI slots. The left
local bus 6 from slot 1 is not routed anywhere and the right local bus signal
from slot 18 is not routed anywhere.
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.
PXI Trigger Bus
All slots on the same 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 the system timing
slot 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.
© National Instruments Corporation 1-9 NI PXIe-1075 User Manual
Chapter 1 Getting Started
Note Although any trigger line may be routed in either direction, it cannot be routed in
more than one direction at a time.
The PXI trigger lines from adjacent PXI trigger bus segments can be routed
in either direction across the PXI trigger bridges. Refer to Figure 1-5 for the
connectivity diagram. 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.

PXIe_SYNC100 to every peripheral slot with an independent driver for
each signal.
An independent buffer (having a source impedance matched to the
backplane and a skew of less than 1 ns between slots) drives PXI_CLK10
to each peripheral slot. You can use this common reference clock signal to
synchronize multiple modules in a measurement or control system.

An independent buffer drives PXIe_CLK100 to each peripheral slot. These
clocks are matched in skew to less than 100 ps. The differential pair must
be terminated on the peripheral with LVPECL termination for the buffer to
drive PXIe_CLK100 so that when there is no peripheral or a peripheral that
does not connect to PXIe_CLK100, there is no clock being driven on the
pair to that slot. Refer to Figure 1-6 for a termination example.

An independent buffer drives PXIe_SYNC100 to each peripheral slot. The
differential pair must be terminated on the peripheral with LVPECL
termination for the buffer to drive PXIe_SYNC100 so that when there is
no peripheral or a peripheral that does not connect to PXIe_SYNC100,
there is no SYNC100 signal being driven on the pair to that slot. Refer to
Figure 1-6 for a termination example.
In summary, PXI_CLK10 is driven to every slot. PXIE_CLK100 and
PXIE_SYNC100 are driven to every peripheral slot.
PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 have the default timing
relationship described in Figure 1-7.

Chapter 1 Getting Started
To synchronize the system to an external clock, you can drive PXI_CLK10
from an external source through the PXI_CLK10_IN pin on the System
Timing Slot. Refer to Table B-5, XP4 Connector Pinout for the System
Timing Slot, for the pinout. When a 10MHz clock is detected on this pin,
the backplane automatically phase-locks the PXI_CLK10, PXIe_CLK100,
and PXIe_SYNC100 signals to this external clock and distributes these
signals to the slots. Refer to Appendix A, Specifications, for the
specification information for an external clock provided on the
PXI_CLK10_IN pin of the system timing slot.
You also can drive a 10MHz clock on the 10 MHz REF IN connector on
the rear of the chassis. Refer to Figure 1-2 for the location of this connector.
When a 10MHz clock is detected on this connector, the backplane
automatically phase-locks the PXI_CLK10, PXIe_CLK100, and
PXIe_SYNC100 signals to this external clock and distributes these signals
to the slots. Refer to Appendix A, Specifications, for the specification
information for an external clock provided on the 10 MHz REF IN
connector on the rear panel of the chassis.
If the 10 MHz clock is present on both the PXI_CLK10_IN pin of the
System Timing Slot and the 10 MHz REF IN connector on the rear of the
chassis, the signal on the System Timing Slot is selected. Refer to Table 1-3
which explains how the 10 MHz clocks are selected by the backplane.

PXIe_SYNC_CTRL
Chapter 1 Getting Started
A copy of the backplane’s PXI_CLK10 is exported to the 10 MHz REF
OUT connector on the rear of the chassis. Refer to Figure 1-2 for the
location of this connector. This clock is driven by an independent buffer.
Refer to Appendix A, Specifications, for the specification information for
the 10 MHz REF OUT signal on the rear panel of the chassis.
PXIe_SYNC100 is by default a 10 ns pulse synchronous to PXI_CLK10.
The frequency of PXIe_SYNC100 is 10/n MHz, where n is a positive
integer. The default for n is 1, giving PXIe_SYNC100 a 100 ns period.
However, the backplane allows n to be programmed to other integers. For
instance, setting n = 3 gives a PXIe_SYNC100 with a 300ns period while
still maintaining its phase relationship to PXI_CLK10. The value for n may
be set to any positive integer from 1 to 255.
The system timing slot has a control pin for PXIe_SYNC100 called
PXIe_SYNC_CTRL for use when n > 1. Refer to Table B-6, XP3
Connector Pinout for the System Timing Slot, for system timing slot pinout.
Refer to Appendix A, Specifications, for the PXIe_SYNC_CTRL input
specifications.
By default, a high-level detected by the backplane on the
PXIe_SYNC_CTRL pin causes a synchronous restart for the
PXIe_SYNC100 signal. On the next PXI_CLK10 edge the
PXIe_SYNC100 signal will restart. This will allow several chassis to have
their PXIe_SYNC100 in phase with each other. Refer to Figure 1-8 for
timing details with this method.

Chassis Cooling Considerations
The NI PXIe-1075 chassis is designed to operate on a bench or in an
instrument rack. Regardless of the configuration you must provide the
cooling clearances as outlined in the following sections.
Providing Adequate Clearance
The primary cooling exhaust vent for the NI PXIe-1075 is on the top of the
chassis. The primary intake vent is on the rear of the chassis where the air
is filtered as it enters the power supply shuttle. The secondary intake and
exhaust vents are located along the sides of the chassis. Adequate clearance
between the chassis and surrounding equipment or blockages must be
maintained to ensure proper cooling of the chassis power supply as well
as the modules plugged into the chassis. These clearances are outlined in
Figure 2-1. The vent locations for the NI PXIe-1075 chassis are shown
in Figure 2-2. Failure to provide these clearances may result in
thermal-related failures in the chassis or modules.

Chassis Ambient Temperature Definition
The chassis fan control system uses intake air temperature as the input for
controlling fan speeds when in Auto Fan Speed mode. Because of this, the
chassis ambient temperature is defined as the temperature that exists just
outside of the fan intake vents on the rear of the chassis. Note that this
temperature may be higher than ambient room temperature depending on
the surrounding equipment and/or blockages present. It is the user’s
NI PXIe-1075 User Manual 2-4 ni.com
responsibility to ensure that this ambient temperature does not exceed the
rated ambient temperature as stated in Appendix A, Specifications. If the
temperature exceeds the stated spec the power switch LED will blink green,
as discussed in the Power Inhibit Switch LED Indicator section of this
chapter.
Setting Fan Speed
The fan-speed selector switch is on the rear panel of the NI PXIe-1075
chassis. Refer to Figure 1-2, Rear View of the NI PXIe-1075 Chassis, to
locate the fan-speed selector switch. Select High for maximum cooling
performance or Auto for improved acoustic performance. When set to
Auto, the fan speed is determined by chassis intake air temperature.
Installing Filler Panels
To maintain proper module cooling performance, install filler panels
(provided with the chassis) in unused or empty slots. Secure with the
captive mounting screws provided.
Installing Slot Blockers
The cooling performance of the chassis can be improved by installing
optional slot blockers. Refer to
Chapter 2 Installation and Configuration

The chassis power inhibit switch has an integrated LED. Refer to
Figure 1-1, Front View of the NI PXIe-1075 Chassis, for the location of
both the Power Inhibit switch and the LED. This LED indicates one of four
different conditions:
• If the inhibit switch LED is steady green (not flashing), the chassis is
powered on and operating normally.
• If the inhibit switch LED is flashing green, the air-intake temperature
has exceeded the chassis operating range.
• If the inhibit switch LED is flashing red, the power supply outputs are
not within voltage regulation requirements.
• If the inhibit switch LED is steady red, the system fans or power supply
fan has failed. The remaining fans will automatically be driven high.

Inhibit Mode Switch
On the rear panel of the chassis there is an Inhibit Mode switch. Refer to
Figure 1-2, Rear View of the NI PXIe-1075 Chassis, for the location. The
Inhibit Mode switch is recessed to prevent it from accidentally being
switched.
The Inhibit Mode switch should be in the Default position when you want
the system controller to control the power supply inhibit. If the user needs
to power on a chassis without a system controller installed the switch
should be in the Manual position.
When the Inhibit Mode switch is set to the Manual position, the power
supplies are enabled, and you can use the Inhibit signal (active low) on
pin 5 of the Remote Inhibit and Voltage Monitoring connector to power off
the chassis. To remotely power off the chassis, connect the Inhibit pin
NI PXIe-1075 User Manual 2-12 ni.com
Chapter 2 Installation and Configuration
(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 Remote Inhibit signal to control the On/Off (standby) state of the chassis, the
Inhibit Mode switch must be in the Manual position.
PXI_CLK10 Rear Connectors
There are two BNC connectors on the rear of the NI PXIe-1075 chassis for
PXI_CLK10, as shown in Figure 1-2, Rear View of the NI PXIe-1075
Chassis. 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. Refer to the System Reference Clock
section of Chapter 1, Getting Started, for details about these signals.
PXI Express System Configuration with MAX
The PXI Platform Services software included with your chassis
automatically identifies your PXI Express system components to generate
a
pxiesys.ini file. You can configure your entire PXI system and
identify PXI-1 chassis through Measurement & Automation Explorer
(MAX), included with your system controller. MAX creates the
pxiesys.ini and pxisys.ini files, which define your PXI system
parameters. MAX also provides an interface to route and reserve triggers
so dynamic routing, through drivers such as DAQmx, avoids
double-driving and potentially damaging trigger lines. For more
information about routing and reserving PXI triggers, refer to
KnowledgeBase 3TJDOND8 at
ni.com/support.
The configuration steps for single or multiple-chassis systems are the same.

NI-VISA. When your system controller and all your chassis are
identified, the required
pxisys.ini or pxiesys.ini file is
complete.
The PXI specification allows for 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. PXI Express devices must provide a driver and
.ini file for
identification. These files are provided as part of the PXI Platform Services
software included with your system controller. The minimum
documentation requirements for PXI-1 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 a PXI-1 chassis is contained in a
chassis.ini file provided by the chassis manufacturer. The information
in this file is combined with information about the system controller to
create a single PXI-1 system initialization file called
pxisys.ini
(PXI System Initialization). The NI system controller uses 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. For detailed information
about initialization files, refer to the PXI specification at
pxiesys.ini and
www.pxisa.org.
Trigger Configuration in MAX
Each chassis has one or more trigger buses, each with eight lines
numbered 0 through 7 that can be reserved and routed statically or
dynamically. Static reservation pre-allocates a trigger line to prevent its
configuration by a user program. Dynamic reservation/routing/deallocation
is on the fly within a user program based upon National Instruments APIs
such as NI-DAQmx. Static reservation of trigger lines can be implemented
by the user in MAX through the Triggers tab. Reserved trigger lines will
not be 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. In the default
configuration, trigger lines on each bus are independent. For example, if
trigger line 3 is asserted on trigger bus 0, by default it will not be
automatically asserted on any other trigger bus.
© National Instruments Corporation 2-15 NI PXIe-1075 User Manual
Chapter 2 Installation and Configuration
Complete the following steps to reserve these trigger lines in MAX.
1. In the Configuration tree, click on the PXI chassis branch you want to
configure.
2. Then, in the right-hand pane, toward the bottom, click on the
Triggers tab.
3. Select which trigger lines you would like to statically reserve.
4. Click the Apply button.
PXI Trigger Bus Routing
Some National Instruments chassis, such as the PXI-1075 and the
PXI-1044/1045, have the capability to route triggers from one bus to others
within the same chassis using the Trigger Routing tab in MAX, as shown
in Figure 2-6.
Note Selecting any non-disabled routing automatically reserves the line in all trigger
buses being routed to. If you are using NI-DAQmx, it will reserve and route trigger lines
for you, so you won’t have to route trigger lines manually.
Complete the following steps to configure trigger routings in MAX.
1. In the Configuration tree, select the chassis in which you want to
route trigger lines.
2. In the right-hand pane, select the Trigger Routing tab near the bottom.
3. For each trigger line, select Route Right, Route Outward From
Middle, or Route Left to route triggers on that line in the described
direction, or select Disabled for the default behavior with no manual
routing.
4. Click the Apply button.
Using System Configuration and Initialization Files
The PXI Express specification allows many combinations of PXI Express
chassis and system modules. To assist system integrators, the
manufacturers of PXI Express chassis and system modules must document
the capabilities of their products. The minimum documentation
requirements are contained in
System integrators, configuration utilities, and device drivers can use these
.ini files.
NI PXIe-1075 User Manual 2-16 ni.com
.ini files, which consist of ASCII text.
Chapter 2 Installation and Configuration
The capability documentation for the NI PXIe-1075 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.
System controllers from NI provide the
NI PXIe-1075 chassis, so you should not need to use the
pxisys.ini file for the
chassis.ini
file. Refer to the documentation provided with the system controller or to
ni.com/support for more information on pxisys.ini and
chassis.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
chassis.ini file. For detailed information regarding
initialization files, refer to the PXI Express specification at
www.pxisa.org.

Chapter 3 Maintenance
Caution Always disconnect the AC power cable before cleaning or servicing the chassis.
Interior Cleaning
Exterior Cleaning
Caution Avoid getting moisture inside the chassis during exterior cleaning, especially
through the top vents. Use just enough moisture to dampen the cloth.
Do not wash the front- or rear-panel connectors or switches. Cover these components while
cleaning the chassis.
Do not use harsh chemical cleaning agents; they may damage the chassis. Avoid chemicals
that contain benzene, toluene, xylene, acetone, or similar solvents.
Use a dry, low-velocity stream of air to clean the interior of the chassis.
Use a soft-bristle brush for cleaning around components.
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth moistened
with clear water. Do not use abrasive compounds on any part of the chassis.
Cleaning the Fan Filters
A dirty fan filter can dramatically affect the cooling performance of an
NI PXIe-1075 chassis. Clean the filter whenever it becomes visibly dirty.
You can easily remove the chassis air filters from the rear of the chassis by
removing the filter retainer. To remove the filter retainer, loosen the
retainer screws. The filter cover and retainer are shown in Figure 1-2, Rear
View of the NI PXIe-1075 Chassis.
Clean the fan filter by washing it in a mild soap solution and then
vacuuming or blowing air through it. Rinse the filter with water and allow
it to dry before reinstalling it in the chassis.
You can replace the fan filter with part number RF.09 R-30 from The Filter
Factory, Inc., Santa Ynez, CA 93460, if necessary. You also may buy from
any other vendor, as long as the filter material is 3/32” thick polyurethane
foam with a porosity of 30 ppi.

Resetting the AC Mains Circuit Breaker
If the NI PXIe-1075 chassis is connected to an AC source and encounters
an over-current condition, the circuit breaker on the rear panel will trip to
prevent damage to the chassis. Complete the following steps to reset the
circuit breaker.
1. Turn off the chassis.
2. Disconnect the AC power cable.
3. Depress the circuit breaker to reset it.
4. Reconnect the AC power cable.
5. Turn on the chassis.
If the circuit breaker trips again, complete the following steps:
1. Turn off the chassis.
2. Disconnect the AC power cable.
3. Remove all modules from the chassis.
4. Complete the procedure described in the Connecting to Power Source
section of Chapter 2, Installation and Configuration. If the power
switch LED is not a steady green, contact National Instruments.
5. Verify that the NI PXIe-1075 chassis can meet the power requirements
of your CompactPCI or PXI Express modules. Overloading the chassis
can cause the breaker to trip. Refer to Appendix A, Specifications.
6. The over-current condition that caused the circuit breaker to trip
may be due to a faulty CompactPCI or PXI Express module. Refer to
the documentation supplied with the modules for troubleshooting
information.

Removal
Installation
Before connecting the power supply shuttle to a power source, read this
section and the Read Me First: Safety and Radio-Frequency Interference
document included with the kit.
The NI PXIe-1075 AC power supply shuttle is a replacement part for the
NI PXIe-1075 AC chassis. Before attempting to replace the power supply
shuttle, verify that there is adequate clearance behind the chassis.
Disconnect the power cable from the power supply shuttle on the back of
the chassis. Identify the ten mounting screws for the NI PXIe-1075 that
attach the power supply shuttle to the chassis. Refer to Figure 1-2, Rear
View of the NI PXIe-1075 Chassis, for the screw locations. Using a Phillips
screwdriver, remove the screws. Pull on the two rear handles of the power
supply shuttle to remove it from the back of the chassis.
Ensure that there is no visible damage to the new power supply shuttle.
Verify that the housing and connector on the new power supply shuttle
have no foreign material inside. Remove the protective cap on the
PXI_CLK10 connector. Install the new power supply shuttle into the
opening on the rear of the chassis. Replace and tighten the ten screws with
a Phillips screwdriver.
Configuration
The fan-speed selector switch is on the rear panel of the power supply
shuttle. Refer to Figure 1-2, Rear View of the NI PXIe-1075 Chassis,
to locate the fan-speed selector. Select High for maximum cooling
performance (recommended) or Auto for quieter operation. Set the Inhibit
Mode switch to the Default position.
