About the PXI-1050 Chassis

Thank you for purchasing the National Instruments PXI-1050 chassis. This chassis integrates a high-performance 8-slot PXI subsystem with a 4-slot SCXI subsystem to offer a complete solution for signal conditioning applications. The PXI section of the chassis accepts an embedded controller and a wide variety of peripheral modules (such as multifunction I/O, digital I/O, and instrument modules). The four SCXI slots integrate signal conditioning modules into your PXI system. These modules provide analog and digital input conditioning, isolation, and other functions. The PXI-1050 is ideal for applications where rack-mount space is limited because it combines the computer, plug-in devices, and signal conditioning in a single chassis. You can daisy-chain additional SCXI chassis to the PXI-1050 to build very high channel-count systems.

Software Programming Choices

You have several options to choose from when programming your National Instruments DAQ and SCXI hardware. You can use National Instruments application software, NI-DAQ, or register-level programming.

National Instruments Application Software

ComponentWorks contains tools for data acquisition and instrument control built on NI-DAQ driver software. ComponentWorks provides a higher-level programming interface for building virtual instruments through standard OLE controls and DLLs. With ComponentWorks, you can use all of the configuration tools, resource management utilities, and interactive control utilities included with NI-DAQ.

LabVIEW features interactive graphics, a state-of-the-art user interface, and a powerful graphical programming language. The LabVIEW Data Acquisition VI Library, a series of VIs for using LabVIEW with National Instruments DAQ hardware, is included with LabVIEW. The LabVIEW Data Acquisition VI Library is functionally equivalent to NI-DAQ software.

Chapter 1 Introduction

LabWindows/CVI features interactive graphics, state-of-the-art user interface, and uses the ANSI standard C programming language. The LabWindows/CVI Data Acquisition Library, a series of functions for using LabWindows/CVI with National Instruments DAQ hardware, is included with the NI-DAQ software kit. The LabWindows/CVI Data Acquisition Library is functionally equivalent to the NI-DAQ software.

VirtualBench features virtual instruments that combine DAQ products, software, and your computer to create a stand-alone instrument with the added benefit of the processing, display, and storage capabilities of your computer. VirtualBench instruments load and save waveform data to disk in the same forms that can be used in popular spreadsheet programs and word processors.

Using ComponentWorks, LabVIEW, LabWindows/CVI, or VirtualBench software will greatly reduce the development time for your data acquisition and control application.

Page 13

Chapter 1 Introduction

NI-DAQ Driver Software

The NI-DAQ driver software is included at no charge with all National Instruments DAQ hardware. NI-DAQ has an extensive library of functions that you can call from your application programming environment. These functions include routines for analog input (A/D conversion), buffered data acquisition (high-speed A/D conversion), analog output (D/A conversion), waveform generation, digital I/O, counter/timer operations, SCXI, PXI Trigger Bus (RTSI), self-calibration, messaging, and acquiring data to extended memory.

NI-DAQ also internally addresses many of the complex issues between the computer and the plug-in board, such as programming interrupts and DMA controllers. NI-DAQ maintains a consistent software interface among its different versions so that you can change platforms with minimal modifications to your code. Whether you are using conventional programming languages or National Instruments application software, your application uses the NI-DAQ driver software, as illustrated in Figure 1-1.

SCXI Subsystem Backplane Overview

You can use the SCXI subsystem in the following ways:

• Install several SCXI modules and a PXI DAQ device in Slot 8 of the PXI backplane to control and/or acquire data from all the SCXI modules.

• Install several SCXI modules and cable one of them to a DAQ device that controls and/or acquires data from all of the SCXI modules.

• Install several SCXI modules and an SCXI-1200 module that operates similarly to a DAQ device, except that it communicates with the host computer through a parallel port instead of the computer plug-in bus.

• Install SCXI modules that are each dedicated to conditioning signals for only a single DAQ device (for example, in parallel mode), or that operate independently and only use the SCXI subsystem as a power source and/or container. You can use the chassis this way in addition to or instead of one of the first three methods.

PXI Subsystem Backplane Overview

Chapter 1 Introduction

The following sections describe the PXI subsystem backplane.

Interoperability with CompactPCI

The PXI backplane is interoperable with PXI-compatible products and standard CompactPCI products. This is an important feature, because many PXI-compatible 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 PXI-1050 backplane P1 connector meet the requirements of the CompactPCI specification for both the peripheral and system modules. The PXI-specific signals are located on the P2 connector and are found only on the signals that are reserved or not used in the CompactPCI 64-bit specification. Therefore, all modules that meet the CompactPCI 64-bit specification requirements will function in the PXI-1050.

Page 19

Chapter 1 Introduction

System Controller Slot

The System Controller slot is located in Slot 1 of the chassis as defined by the PXI specification. It has three controller expansion slots, which are used for system controller modules wider than one slot. As defined in the PXI specification, these slots allow the controller to expand to the left so it does not use up peripheral slots.

Peripheral Slots

The PXI-1050 has seven peripheral slots located in Slots 2 through 8. You can use PXI modules in peripheral slots to add functionality to the PXI subsystem not already provided by the system controller. Examples of PXI peripheral modules are multifunction I/O, digital I/O, and instrument modules. Some peripheral slots also have special capabilities, such as the Star Trigger slot and the SCXI Control slot, which are explained in the following sections.

Star Trigger Slot

The Star Trigger slot is located at Slot 2. This slot has a dedicated trigger line between each peripheral slot (refer to Figure 1-4) and is intended for modules with Star Trigger functionality to provide individual triggers to all other peripherals. However, if you do not require advanced trigger functionality, you can install any standard peripheral module into this slot.

Local Bus

The PXI backplane local bus is a daisy-chained bus that connects each peripheral slot with its adjacent left and right peripheral slots, as shown in Figure 1-4.

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 modules or provide a high-speed side-band communication path that does not affect the PXI bandwidth.

Local bus signals may range from high-speed TTL signals to analog signals as high as 42 V. Initialization software keys adjacent modules to prohibit the use of incompatible devices. This software uses the configuration information specific to each peripheral module to evaluate compatibility. This method is a flexible way to define local bus functionality that is not limited by keying hardware.

SCXI Connection

Slot 8 of the PXI backplane has connections for a PXI peripheral module to control the SCXI subsystem. These connections use the available local bus right pins (PXI_LBR0:12). The SCXI connection passes communication, timing, and analog signals between the SCXI backplane and the PXI module in Slot 8.

Trigger Bus

The eight PXI trigger lines are bused to each slot. You can use the 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.

Chapter 1 Introduction

System Reference Clock

The PXI-1050 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 1 ns 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

disables the backplane 10 MHz source.

Installation and Configuration

This chapter describes how to prepare and operate your PXI-1050 chassis.

Mounting Information

The PXI-1050 is designed to operate on a bench or in an instrument rack. Determine how you want to use your PXI-1050 and follow the appropriate installation instructions.

Apertures in the rear, along both sides, and on top of the chassis facilitate power supply and module cooling. Air enters through filters and fan inlets located in the lower rear of the chassis and exits through the upper side sections and through the top. Place your PXI-1050 on a bench top or in an instrument rack so that the fans (air inlets) and the air outlet apertures along both sides of the chassis have adequate ventilation. Keep other equipment a minimum of 3.0 in. (76.2 mm) away from the air inlets and outlets.

Install your chassis for easy access to the rear panel. This simplifies the air filter replacement.

Rack-mount applications require the optional rack-mount kit available from National Instruments. Refer to the rack-mount kit documentation to install your PXI-1050 in an instrument rack.

Chassis Configuration

Chassis configuration involves selecting an SCXI subsystem address, line voltage, and fuse value, described briefly in the following sections.

SCXI Subsystem Address Selection

Note Unless you are using multiple chassis and need to configure one or more SCXI

chassis for a different address, you can skip this section. The SCXI subsystem will have the factory-default address of 0.

Page 23

Chapter 2 Installation and Configuration

You can configure the SCXI subsystem for one of 32 different addresses so that you can connect multiple SCXI chassis to the same control source. The five switches on the front panel of Slot 0 determine the chassis address. Switches one through five represent the values 1, 2, 4, 8, and 16 respectively, when set to the ON position. When set to the OFF position, their value is 0. The chassis address is the sum of the switch values. Figure 2-1 shows examples of both the factory-default setting of the chassis address 0 and the switch setting for chassis address 19.

5 4 3 2 1

1 Chassis Default Address = 0 2 Address = 19 3ON

Figure 2-1. Address Setting Examples

Line Voltage Selection and Fuse Values

The voltage selection wheel and fuse should be correct for operation in your geographical region (the -0x extension of the kit part number corresponds to your geographical region). Check the voltage on the voltage selection wheel to ensure that you have the correct voltage setting and fuse.

The PXI-1050 chassis can operate with line voltages of 100, 120, 220, and 240 VAC. The voltage selection wheel in the power entry module determines the voltage for which the chassis is configured. Identify the operating voltage by looking at the number on the power entry module when the selection wheel door is closed. The fuse is a 5 by 20 mm SLO-BLO type, which has a current rating relative to the operating voltage. Table 2-1 shows the proper voltage selection and fuse ratings for different geographical regions.

Maintenance

This chapter describes basic maintenance procedures for the PXI-1050 chassis.

Maintenance Procedures

Service Interval

Clean the chassis fan filters at a maximum interval of six months. Depending upon the amount of use and ambient dust levels in the operating environment, the filters 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 section is designed for use by qualified service personnel.

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

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

Caution Always power off the chassis and disconnect the power cable before cleaning or

servicing the chassis.

Interior Cleaning

Use a dry, low-velocity stream of air to clean the chassis interior. Use a soft-bristle brush for cleaning around components.

Page 30

Chapter 3 Maintenance

Cautions Do not use abrasive compounds on any part of the chassis.

Avoid getting moisture inside the chassis during exterior cleaning.

Do not wash the front- or rear-panel connectors or switches. Cover these components while cleaning the chassis.

Do not use chemical cleaning agents: they may damage the chassis. Avoid chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.

Exterior Cleaning

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.

PXI Subsystem Fan Filter Cleaning

To easily remove the chassis cooling filters from the rear of the chassis, remove the plastic housing attached to each fan.

To clean the fan filters, wash them in a mild soap solution and then vacuum or blow air through them. Rinse the filters with water and allow them to dry before reinstalling them onto the chassis.

SCXI Subsystem Fan Filter Cleaning

The fan on the rear of the SCXI subsystem cools the SCXI subsystem and its modules. To keep the fan effective, the fan filters must be clean. Dust and dirt accumulation reduces airflow, which makes the inside of the chassis hotter, shortening the life of the chassis and modules. Complete the following steps to clean the fan filters:

1. Power off the chassis.

2. Remove the power cable from the power-entry module.

3. Place the chassis face down on a flat surface so that the fan is on top. If the chassis is so heavily cabled that you cannot practically place it in this position, leave the chassis as it is but be careful to support the fan during removal and reinstallation to prevent breaking the fan wires.

To remove the fan filter, remove the four screws that secure the fan and filter to the rear of the chassis. When removing the last screw, be careful to hold the fan to prevent breaking the fan wires.

NI PXI-1050 User Manual 3-2 ni.com

Page 31

4. Clean the fan filter by moving the filter around under a gentle stream of cold tap water until all the dust has been removed. Dry the filter.

5. Replace the fan filter by aligning the fan and filter with the fan holes, making sure that the label side of the fan is face down. Reinstall the four screws and make sure the assembly is secure.

Resetting the AC Main Circuit Breaker

If your PXI subsystem encounters an over-current condition, the circuit breaker located on the rear panel will trip to prevent chassis damage. Refer to Figure 1-2, Front View of the PXI-1050 Chassis, and Figure 1-3, Rear

View of the PXI-1050 Chassis, as you complete the following steps:

1. Turn off the PXI power switch.

2. Depress the circuit breaker to reset it.

3. Turn on the PXI power switch.

If the circuit breaker trips again, complete the following steps:

1. Turn off the PXI power switch.

2. Remove all modules from the chassis.

3. Depress the circuit breaker to reset it.

4. Turn on the power switch and verify that the circuit breaker does not trip.

5. Verify that your PXI-1050 can meet the power requirements of your CompactPCI or PXI modules. Overloading the chassis can cause the breaker to trip. Refer to Appendix A, Specifications, for power requirements.

6. The over-current condition that caused the circuit breaker to trip may be due to a faulty CompactPCI or PXI module. Refer to your module documentation to troubleshoot your modules.

SCXI Subsystem Fuse Replacement

Power Entry Module Fuse Replacement

Caution Disconnect all power before removing cover.

Refer to Figure 1-3, Rear View of the PXI-1050 Chassis, as you complete the following steps to replace the power-entry module fuse:

1. Power off the chassis.

2. Remove the power cable from the power-entry module.

3. Using a flathead screwdriver, pry the door to the voltage selection wheel open from the top.

4. Pull out the fuse drawer.

5. Remove the fuse.

6. Install the new fuse in the drawer.

7. Reinsert the fuse drawer in the right side slot with the arrow pointing to the right.

8. Close the door.

9. Reinsert the power cable.

SCXI Subsystem Backplane Fuse Replacement and Check

In addition to the power entry module fuse, the analog supply lines on the backplane are fused at 1.5 A. The fuse manufacturer is Littelfuse, part number 251 01.5.

If you are going to make your own modules, fuse your module at 250 mA to avoid blowing the backplane fuses. Fusing your module also better protects your module because a failure can result in a large amount of current drawn, but not enough to blow the backplane fuses.

The backplane fuses are located behind the SCXI subsystem fan.

Complete the following steps to check or replace fuses:

1. Remove the appropriate fan and filter from the rear of the chassis, following the instructions in the SCXI Subsystem Fan Filter Cleaning section in this chapter. Make sure to power off the chassis and remove the power cable.

2. The fuse marked with a copper + on the backplane is for the positive analog supply, and the fuse marked with a copper – is for the negative

NI PXI-1050 User Manual 3-4 ni.com

Page 33

analog supply. To check whether a fuse is blown, connect an ohmmeter across the leads. If the reading is not 0 Ω, replace the fuse.

3. Use a pair of needle-nose pliers to carefully extract the fuse.

4. Take a new fuse and bend its leads so the component is 1.27 cm (0.5 in.) long (the dimension between the fuse sockets), and clip the leads to a length of 0.635 cm (0.25 in).

5. Using the needle-nose pliers, insert the fuse into the socket holes.

6. Repeat, if necessary, for the other fuse.

7. Check the fan filter and, if it is dirty, clean it as described in the SCXI

Subsystem Fan Filter Cleaning section of this chapter.

8. Reinstall the fan and filter.

Star Trigger slot This slot is located at Slot 2 and has a dedicated trigger line between each

peripheral slot. Use this slot for a module with Star Trigger functionality that can provide individual triggers to all other peripherals.

System Controller A module configured for installation in Slot 0 of a VXIbus mainframe.

This device is unique in the VXIbus system in that it performs the VMEbus 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 VXIbus backplane, or both.
