Chapter 1 Getting Started Interoperability with CompactPCI The PXI-1052 backplane is interoperable with 5 V and universal PXI-compatible products and standard CompactPCI products. This is an important feature because some PXI user systems can 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.
Slot 4 of the PXI backplane has connections for a PXI peripheral module such as an NI PXI DAQ module, an NI PXI DMM module, or an NI-Switch controller 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 low-voltage analog bus signals between the SCXI subsystem and the PXI module in Slot 4.
SCXI Subsystem Overview To use the SCXI subsystem of the PXI-1052, you must have a DAQ/DMM/Switch controller module in Slot 4 of the PXI subsystem to control and/or acquire data from the SCXI modules. The chassis address of the SCXI subsystem is hard-wired as 0.
Chapter 2 Installation and Configuration • Chassis Cooling Considerations The PXI-1052 is designed to operate on a bench or in an instrument rack. Determine how you want to use the PXI-1052 and follow the appropriate installation instructions. Providing Adequate Clearance Openings in the top and along both sides of the chassis facilitate power supply and module cooling.
Install the chassis so that you can access the rear panel easily. This simplifies cleaning or replacing the air filters. Setting Fan Speed The fan-speed selector switch is on the rear panel of the PXI-1052. Refer to Figure 1-2, selector switch. Select HIGH for maximum cooling performance (recommended) or AUTO for quieter operation.
Caution To completely remove power, you must disconnect the AC power cable. The power switch allows you to power on the chassis or place it in standby mode. Push the power switch to the On (recessed) position (if not already on).
Power Switch LED Indicators The chassis has two LEDs next to the power switch. The system power LED indicates the power status for the chassis. The SCXI power LED, when lit, indicates that power is available to the SCXI subsystem. The system power LED indicates one of three different conditions.
Plug in the PXI chassis before installing the controller. The power cord grounds the chassis and protects it from electrical damage while you install the controller. Make sure the chassis power switch is in the Off (Standby) position. Install the controller into the system controller slot (Slot 1, indicated...
Complete the following steps to install a module. NI PXI-1052 User Manual Make sure the power switch is in the Off position (NI LEDs on the front of the chassis are not lit). Install a module into a chassis slot by completing the following steps: Place the module card edges into the front module guides (top and bottom).
PXI system. After installing the NI PXI-1052 User Manual Power off the PXI/SCXI chassis using the switch shown in Figure 1-1, Front View of the PXI-1052 Chassis. To make sure that the chassis power is off, verify that the LEDs are not lit.
Chapter 2 Installation and Configuration Trigger Configuration in MAX Each chassis has one or more trigger buses, each with eight lines numbered 0 through 7 that you can reserve and route statically or dynamically. Static reservation pre-allocates a trigger line to prevent its configuration by a user program.
Make sure the SCXI backplane is powered on, since it is powered separately from the PXI backplane. The SCXI chassis power switch is located on the rear panel of the PXI-1052 chassis. Double-click the Measurement & Automation icon on the desktop to launch MAX.
Chapter 2 Installation and Configuration There is an alternative way to add an SCXI chassis. Right-click Devices & Interfaces»NI-DAQmx Devices and select Create New NI-DAQmx Device. Select NI-DAQmx SCXI Chassis and choose the PXI-1052 (SCXI) chassis. Configure the Chassis Complete the following steps to configure the chassis. NI PXI-1052 User Manual Click Finish.
Chapter 2 Installation and Configuration You need not adjust the information in the cabling tab if you are using standard Note multiplexed mode operation. If you are using parallel mode operation, multichassis configuration, or another special configuration, adjust the options on the Cabling tab. 10.
Chapter 2 Installation and Configuration Follow the online instructions to create a new task. You now can use the task in an application. Refer to the DAQ Assistant Help or application software documentation for more information about using a task or generating code.

Chapter 3 Maintenance Cleaning Always disconnect the AC power cable before cleaning or servicing the chassis. Caution Cleaning procedures consist of exterior and interior cleaning of the chassis and cleaning the fan filters. Refer to the module user documentation for information on cleaning individual CompactPCI, SCXI, or PXI modules.
Disconnect the AC power cable. Remove all modules from the chassis. Complete the procedure described in the section of Chapter 2, Installation and power switch LED is not a steady green, contact NI through the information given in Appendix C, Services. Chapter 3 Maintenance...

Chapter 3 Maintenance NI PXI-1052 User Manual Verify that the PXI-1052 can meet the power requirements of the installed CompactPCI, SCXI, or PXI modules. Overloading the chassis can cause the breaker to trip. Refer to Appendix A, Specifications. The over-current condition that caused the circuit breaker to trip can be due to a faulty CompactPCI, SCXI, or PXI module.
