PXI-1056 Backplane Overview

Interoperability with CompactPCI

The PXI-1056 backplane is interoperable with 5 V and universal 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 connectors meet the requirements of the CompactPCI specification for both peripheral and system modules. Refer to Appendix B, Pinouts, for pinout information.

The PXI-specific signals are on the backplane P2 connectors and are found only on those 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-1056. Refer to Appendix B, Pinouts, for pinout information.

Note The PXI-1056 backplane is 32-bit PCI. 64-bit CompactPCI cards will operate in

32-bit mode in this chassis.

Chapter 1 Getting Started

The PXI-1056 backplane has +5 V V(I/O). Refer to the CompactPCI Specification PICMG 2.0 R 3.0 for details regarding V(I/O).

System Controller Slot

The system controller slot is slot 1 of the chassis as defined by the PXI Specification. It has one controller expansion slot 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.

Star Trigger Slot

The star trigger (ST) slot is slot 2. This slot has dedicated equal-length trigger lines between slot 2 and peripheral slots 3 through 15 (refer to Figure 1-3). The PXI Specification defines only 13 star trigger lines; therefore, the last three slots do not receive a star trigger. Slot 2 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.

Chapter 1 Getting Started

Peripheral Slots

Local Bus

The star trigger slot can also be used to provide a PXI_CLK10 signal to the backplane. For more information regarding PXI_CLK10, refer to the

System Reference Clock section.

There are 17 3U-sized peripheral slots including the star trigger slot. Three of these slots can only be used for 3U modules. The chassis has a number of peripheral slots that can also be used in a 6U configuration. They can be used for a mix of 3U and 6U modules, or they can be used to hold up to 7 6U modules.

The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with adjacent peripheral slots (refer to Figure 1-3). For example, slot 2’s right local bus connects to slot 3’s left local bus, and so on.

The left local bus signal lines on slot 2 are used for star trigger and do not connect to slot 1. The right local bus signal lines on slots 4, 11, and 18 are not routed anywhere. Likewise, the left local bus signal lines on shots 5 and 12 are not routed anywhere.

Each local bus is 13 lines wide and can pass analog signals up to 42 V between cards or provide a high-speed TTL side-band digital communication path that does not reduce the PXI bus bandwidth.

Initialization software uses the configuration information specific to adjacent peripheral modules to evaluate local bus compatibility.

Trigger Bus

Note Although any trigger line may be routed in either direction, it cannot be routed in

more than one direction at a time.

All slots on each 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 slot 2 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.

The PXI trigger lines from adjacent PXI trigger bus segments can be routed in either direction across the PXI 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 PXI-1056 supplies 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 overrides

the backplane’s 10 MHz source.

Chassis Cooling Considerations

The PXI-1056 is designed to operate on a bench or in an instrument rack. Determine how you want to use the PXI-1056 and follow the appropriate installation instructions.

Providing Adequate Clearance

Apertures in the rear and along the left side of the chassis facilitate power supply and module cooling. Air enters through a filter and fan inlet in the right rear of the chassis and exits through the left side of the chassis, as shown in Figure 2-1. Place the PXI-1056 on a bench top or in an instrument rack so that the fan (air inlet) and the air outlet apertures along the right side of the chassis have adequate ventilation. Keep other equipment a minimum of 76.2 mm (3 in.) away from the air inlet on the rear of the chassis.

When rack mounting the PXI-1056, provide at least 44.5 mm (1.75 in.) clearance on the right side of the unit for adequate venting. High-power applications may require additional clearance.

PXI System Configuration with MAX

Configuration of the PXI system is handled through Measurement & Automation Explorer (MAX), included on the NI Driver CD-ROM packaged with your kit. MAX creates the the layout and parameters of your PXI system. After installing the software on the NI Driver CD-ROM, the MAX icon will be present on the desktop. The configuration steps for single- or multiple-chassis systems are the same.

pxisys.ini file which defines

NI PXI-1056 User Manual 2-14 ni.com

Chapter 2 Installation and Configuration

Figure 2-5. Multichassis Configuration in MAX

Basic PXI System Configuration

1. Launch MAX.

2. In the Configuration tree, click on the Devices and Interfaces branch

to expand it.

3. If the PXI system controller has not yet been configured, it will be labeled “PXI System (Unidentified).” Right-click on this entry to display the popup menu, then select the appropriate controller model from the Identify As submenu.

4. Click on the PXI System controller and the chassis (or multiple chassis, in a multi-chassis configuration) will be listed below it. Identify each chassis by right-clicking on its entry, then selecting the appropriate chassis model through the Identify As submenu. Further expanding the PXI System branch will show all of the devices in the system that can be recognized by NI-VISA. Once your controller and all of your chassis have been identified, the required will be complete.

pxisys.ini file

Chapter 2 Installation and Configuration

5. Apply the chassis number labels (shown in Figure 2-6) included with your kit to each chassis in your PXI system, and write in the chassis number accordingly in the white space.

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.

Figure 2-6. Chassis Number Label

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-1045 and the PXI-1056, 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 2-5. This tab allows the routing of triggers from any single trigger bus to all of the other trigger buses in the chassis.

NI PXI-1056 User Manual 2-16 ni.com

Chapter 2 Installation and Configuration

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 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

.ini files.

The capability documentation for the PXI-1056 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 National Instruments use the Measurement & Automation Explorer (MAX) to generate the

chassis.ini file.

Device drivers and other utility software read the

pxisys.ini file from the

pxisys.ini file to

obtain system information. Device drivers should have no need to directly read the initialization files, refer to the PXI specification at

chassis.ini file. For detailed information regarding

www.pxisa.org.

Maintenance

This chapter describes basic maintenance procedures you can perform on the PXI-1056 chassis.

Caution Disconnect the power cable prior to servicing the PXI-1056 chassis.

Service Interval

Clean the chassis fan filter at a maximum interval of six months. Depending on the amount of use and ambient dust levels in the operating environment, the filter may require more frequent cleaning.

Clean dust from the chassis exterior (and interior) as needed, based on the operating environment. Periodic cleaning increases reliability.

Preparation

The information in this chapter is designed for use by qualified service personnel. Read the Read Me First: Safety and Radio-Frequency Interference document included with your kit before attempting any procedures in this chapter.

Caution Many components within the chassis are susceptible to static discharge damage.

Service the chassis only in a static-free environment. Observe standard handling precautions for static-sensitive devices while servicing the chassis. Always wear a grounded wrist strap, or equivalent, while servicing the chassis.

Cleaning

Caution Always disconnect the AC power cable before cleaning or servicing the chassis.

Cleaning procedures consist of exterior and interior cleaning of the chassis and cleaning the fan filters. Refer to your module user documentation for information on cleaning individual CompactPCI or PXI modules.

Chapter 3 Maintenance

Interior Cleaning

Exterior Cleaning

Cautions 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 and Replacing the Fan Filter

A dirty fan filter can dramatically reduce the cooling performance of the PXI-1056 chassis. Clean the filter whenever they become visibly dirty. You can easily remove the chassis air filter from the rear of the chassis by removing the filter retainer. The filter cover and retainer are shown in Figure 1-2, Rear View of the PXI-1056 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 on the chassis.

If desired, you can replace the fan filter with part number 150139-C from Air Filtration Products, Inc., Tucson, AZ 85705.

The same filter media can be purchased in sheets, and cut to the appropriate size.
