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-to­PCI 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-to­PCI 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.

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 32­bit 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.

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.

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.

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.
Note Although any trigger line may be routed in either direction, it cannot be
routed in more than one direction at a time.

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
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 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.

Remote Inhibit and Fault Monitoring

The PXIe-1086DC chassis supports remote inhibit and fault monitoring through a 4-pin terminal block on the chassis front panel. Refer to Front View of the PXIe-1086DC to locate this connector.
Table 6. Remote Inhibit and Fault Connector Pinout
Pin Signal
1 Remote Inhibit (active low)
2 Ground
3 Remove Fault (active high)
4 Ground
When the chassis Inhibit Mode switch is in the Manual position, you can use the Remote Inhibit signal to control the chassis power supplies. Refer to the Inhibit Mode Switch section for details.
The Remote Fault signal is an output signal that is asserted high when any chassis fault is detected. You can use this signal to monitor the overall chassis health.

Inhibit Mode Switch

On the rear panel of the chassis there is an Inhibit Mode switch. Refer to Rear View of the
PXIe-1086DC to locate this switch.
24 | ni.com | PXIe-1086DC User Manual and Specifications
The Inhibit Mode switch should be in the Default position when normal power inhibit switch functionality is desired. 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 1 of the Remote Inhibit and Fault connector to power off the chassis. To power off the chassis remotely, connect the Inhibit pin (pin 1) to a Logic Ground pin (pin 2). 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 Front Panel Connectors

There are two SMA connectors on the front of the PXIe-1086DC 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. Refer to the System
Reference Clock section 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 your chassis through Measurement & Automation Explorer (MAX), included with your system controller. PXI Platform Services creates the
pxiesys.ini and pxisys.ini file, which define your PXI system parameters.
MAX provides the following chassis information:
• Asset information, such as serial number or part number
• Chassis number
• Voltages, temperatures, and fan speeds
• Ethernet monitoring port configuration
• Slot details
• Chassis self-test
• Firmware Update
PXIe-1086DC User Manual and Specifications | © National Instruments | 25
Figure 16. MAX Interface

Trigger Configuration in MAX

PXI Platform Services provides an interface to route and reserve triggers so dynamic routing, through drivers such as NI-DAQmx, avoids double-driving and potentially damaging trigger lines. For more information about routing and reserving PXI triggers, refer to Info Code wf17sp at ni.com/support.
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 on National Instruments APIs such as NI-DAQmx. NI recommends dynamic reservations and routing are used whenever possible. If static reservations are required, static reservation of trigger lines can be implemented by the user in MAX through the Triggers tab. PXI modules dynamically configured by programs such as NI-DAQmx will not use reserved trigger lines. This prevents the instruments from double­driving 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 is not asserted automatically on any other trigger bus.
Complete the following steps to reserve these trigger lines in MAX.
1. In the Configuration tree, click the PXI chassis branch to configure.
2. In the lower right pane, click the Triggers tab.
3. Select the trigger lines to statically reserve.
4. Click the Save button.
26 | ni.com | PXIe-1086DC User Manual and Specifications

PXI Trigger Bus Routing

Some National Instruments chassis, such as the PXIe-1086DC, have the capability to route triggers from one bus to others within the same chassis using the Trigger Routing tab in MAX.
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 Triggers 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 Save button.
Figure 17. Trigger Configuration

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 .ini files, which consist of ASCII text. System integrators, configuration utilities, and device drivers can use these .ini files.
PXIe-1086DC User Manual and Specifications | © National Instruments | 27
The capability documentation for the PXIe-1086DC 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 pxisys.ini file for the
PXIe-1086DC chassis, so you should not need to use 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.
