PXIe-1086DC Chassis Backplane Overview
Interoperability with CompactPCI
The design of the PXIe-1086DC provides you the flexibility to use the following devices in a
single PXI Express chassis:
• PXI Express compatible products
• CompactPCI Express compatible 2-Link system controller products
• CompactPCI Express compatible Type-2 peripheral products
• PXI peripheral products modified to fit in a hybrid slot
• Standard CompactPCI peripheral products modified to fit in a hybrid slot
System Controller Slot
The system controller slot is Slot 1 of the chassis and is a 2-Link configuration system slot as
defined by the CompactPCI Express and PXI Express specifications. It has three 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 it from using peripheral slots.
The backplane connects the system slot to two PCI Express switches using a Gen-2 x8 and a
Gen-2 x16 PCI Express link. These switches distribute PCI Express connections to the
peripheral slots and to two PCI Express-to-PCI bridges to provide PCI buses to the hybrid
peripheral slots. Refer to PXIe-1086DC PCI Express Backplane Diagram.
System slot link 1 is a Gen-2 x8 PCI Express link to PCI Express switch 1, providing a
nominal bandwidth of 4 GB/s (single direction) between the system controller and PCI
Express switch 1. PXI Express peripheral slots 2-10 are connected to PCI Express switch 1
with Gen-2 x8 PCI Express links and are downstream of system slot link 1. PCI Express-to-
PCI bridge 1 is connected to PCI Express switch 1 and provides a 32-bit, 33 MHz PCI bus for
hybrid peripheral slots 2-9. PCI Express switch 1 also is connected to PCI Express switch 2
with a Gen-2 x8 PCI Express link for advanced backplane configurations.
System slot link 2 is a Gen-2 x16 PCI Express link to PCI Express switch 2, providing a
nominal bandwidth of 8 GB/s (single direction) between the system controller slot and PCI
Express switch 2. PXI Express peripheral slots 11-18 are connected to PCI Express switch 2
with Gen-2 x8 PCI Express links and are downstream of system slot link 2. PCI Express-to-
PCI bridge 2 is connected to PCI Express switch 2 and provides a 32-bit, 33 MHz PCI bus for
hybrid peripheral slots 11-18. PCI Express switch 2 also is connected to PCI Express switch 1
with a Gen-2 x8 PCI Express link for advanced backplane configurations.
The system controller slot also has connectivity to some PXI features such as: PXI_CLK10,
PXI Star, PXI Trigger Bus and PXI Local Bus 6.
6| ni.com | PXIe-1086DC User Manual and Specifications

By default, the system controller will control the power supply with the PS_ON# signal. 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 for details about the Inhibit Mode switch.
Hybrid Peripheral Slots
The chassis provides 16 hybrid peripheral slots as defined by the PXI-5 PXI Express Hardware
Specification: slots 2 to 9 and slots 11 to 18. A hybrid peripheral slot can accept the following
peripheral modules:
• A PXI Express peripheral with x8, x4, or x1 PCI Express link through a switch to the
system slot. Each PXI Express peripheral slot can link up to a Gen-2 x8 PCI Express,
providing a maximum nominal single-direction bandwidth of 4 GB/s.
• A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link through a
PCI Express switch to the system slot.
• A hybrid-compatible PXI Peripheral module 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.

System Timing Slot
The system timing slot is slot 10. The system timing slot accepts the following peripheral
modules:
• A PXI Express System Timing Module with x8, x4, or x1 PCI Express link to the system
slot through a PCI Express switch. Each PXI Express peripheral slot can link up to a
Gen-2 x8 PCI Express, providing a maximum nominal single-direction bandwidth of 4
GB/s.
• A PXI Express Peripheral with x8, x4, or x1 PCI Express link to the system slot through a
PCI Express switch.
• A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link to the
system slot through a PCI Express switch.
The system timing slot has three (3) dedicated differential pairs (PXIe_DSTAR) connected
from the TP1 and TP2 connectors to the XP3 connector for each PXI Express hybrid
peripheral slot, as well as routed back to the XP3 connector of the system timing slot, as
shown in the following figure. You can use the PXIe_DSTAR pairs 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 the following figure for more details.
The system timing slot has a pin (PXI_CLK10_IN) through which a system timing module
may source a 10 MHz clock to which the backplane phase-locks. 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.

PXI Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with
adjacent peripheral slots to the left and right.
The backplane routes PXI Local Bus 6 between all slots. The left local bus 6 from slot 1 is not
routed anywhere, and the right local bus 6 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 on the lines, 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 trigger 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.
Note Although any trigger line may be routed in either direction, it cannot be
routed in more than one direction at a time.

System Reference Clock
The PXIe-1086DC chassis supplies PXI_CLK10, PXIe_CLK100 and 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.
PXIe-1086DC User Manual and Specifications | © National Instruments | 9

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.
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.
PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 have the default timing relationship
described in the following figure.
Figure 6. System Reference Clock Default Behavior
PXIe_CLK100

0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9
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 the System
Timing Slot XP4 Connector Pinout section 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 the 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 10 MHz clock on the 10 MHz REF IN connector on the front of the
chassis. When a 10 MHz 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 the Specifications section for the
specification information for an external clock provided on the 10 MHz REF IN connector on
the front 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 front of the chassis, the signal on the System Timing
Slot is selected. Refer to the following table which explains how the 10 MHz clocks are
selected by the backplane.

A copy of the backplane’s PXI_CLK10 is exported to the 10 MHz REF OUT connector on the
front of the chassis. This clock is driven by an independent buffer.
PXIe_SYNC_CTRL
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 example, setting n = 3 gives a PXIe_SYNC100 with a 300 ns period while still
maintaining its phase relationship to PXI_CLK10. The value for n can be 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 System Timing Slot XP3 Connector Pinout for the pinout. Refer to the
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 restarts. This allows several chassis to have their PXIe_SYNC100 in
phase with each other. Refer to the following figure for timing details with this method.

Chassis Cooling Considerations
The PXIe-1086DC chassis is designed to operate on a bench or in an instrument rack. The
chassis must be oriented horizontally with the primary exhaust vent at top. Vertical orientation
with the chassis handle up is not a supported configuration. 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 PXIe-1086DC is on the top of the chassis. The
primary intake vent is on the bottom of the chassis. The secondary intake vents are located
along on the rear 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 the
following figures. 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 ambient intake air temperatures for controlling fan speeds
when in Auto Fan Speed mode. Because of this, the chassis ambient temperature is defined as
the temperature of the air just outside of the fan intake vents on the bottom of the chassis. Note
that this temperature may be higher than ambient room temperature depending on the
surrounding equipment and/or blockages present. Ensure ambient intake temperatures do not
exceed the ratings in the Operating Environment section of the PXIe-1086DC Specifications.
If the temperature exceeds the stated spec, the front-panel temperature LED blinks red.
Setting Fan Speed
The fan-speed selector switch is on the chassis rear panel. Refer to Rear View of the
PXIe-1086DC to locate the fan-speed selector switch. Select High for maximum cooling
performance or Auto for improved acoustic performance. When set to Auto, the chassis intake
air temperature determines the fan speed.

The PXIe-1086DC ships with a power cord that has an appliance coupler and leads for
connection to the source. The cord requires custom termination. The following figure shows
the cord connector pinout.
You can order an additional or replacement cord from National Instruments. Part number
782108-01 is a US/CAN approved 3 m, three-conductor, 18 AWG cord with leads and suitable
for use in North America. Part number 785863-01 is an international harmonized power cord,
3 m, three-conductor, 1.0mm2 cord with leads and suitable for use in the EU and
internationally. Installation must be done in accordance with local electric codes.
Caution The PXIe-1086DC chassis must have a safety ground (protective earth),
which is connected by the installer to the premise safety ground system for safe
operation. The supplied power cord has a green ground wire for this purpose. The
safety ground method shall be reliable and meet applicable safety codes.
Attention Pour un fonctionnement en toute sécurité, le châssis PXIe-1086DC doit
disposer d'un fil de protection (mise à la terre) relié par l'installateur au système de
mise à la terre du site. Le cordon d'alimentation fourni dispose d'un fil de protection
vert prévu à cet effet. La méthode de mise à la terre doit être fiable et respecter les
codes de sécurité applicables.
The Earth Ground Terminal on the rear of the chassis must be used where the power cord is
terminated via a standard power plug (for example, IEC 60320, NEMA 5-15). This provides a
supplemental protective earthing connection to prevent shock hazards if the ground in the plug
were to be interrupted. Complete the following steps to connect a protective conductor to this
terminal:
1. Connect a 18 AWG wire to the Earth Ground Terminal using a grounding lug. The wire
must have green insulation with a yellow stripe or must be noninsulated (bare). The lug
must be sized for the M4 x 6 screw.
2. Attach the opposite end of the wire to permanent earth ground using toothed washers or a
toothed lug.

Notice
To ensure the specified EMC performance with a second chassis power supply,
install a snap-on ferrite bead (NI part number 711849-01) onto the power cord as
close to the input connector as possible. You can order this ferrite bead directly from
NI using the Order By Part Number link on the home page at ni.com. Order the
following part number: 781233-02 EMI suppression ferrite, 10.2 mm (includes NI
part number 711849-01 (Fair-Rite 0443167251, type 43, round cable, 10.2 mm/
0.402 in. ID, 225 Ω @ 100 MHz)).
Power-On Test
Caution Do not install modules prior to performing the following power-on test.
Caution To completely remove power, you must disconnect all power cables.
The PXIe-1086DC chassis has two slots for inserting power supplies on the rear of the chassis.
A power supply must be installed in one or both of these slots to power on the chassis.
Use the Inhibit Mode switch to power on the chassis or place it in standby mode. Set the
Inhibit Mode switch on the back of the chassis to the Manual position. Observe that all fans
become operational and that all chassis LEDs are steady green. Set the Inhibit Mode switch
back to the Default position to allow the system controller to control the power supply.
