1 Getting Started This chapter includes information about the features of the NI PXI-8250 and information about operating the hardware. About the NI PXI-8250 Module The NI PXI-8250 module monitors the status parameters of a chassis and displays the status information with front panel LEDs and an alert relay.
Chapter 1 Getting Started What You Need to Get Started To set up and use the NI PXI-8250 module, you must have the following items: ❑ An NI PXI-8250 System Monitor module ❑ An NI PXI-1042, NI PXI-1042Q, or NI PXI-1045 chassis ❑ This manual ❑ Optional: The NI System Monitor 1.
Chapter 1 Getting Started If you need to clean the device, use a soft, nonmetallic brush. Make sure that the device is completely dry and free from contaminants before returning it to service. Operate the device only at or below Pollution Degree 2. Pollution is foreign matter in a solid, liquid, or gaseous state that can reduce dielectric strength or surface resistivity.
Chapter 1 Getting Started equipment, circuits powered by regulated low-voltage sources, and electronics. NI PXI-8250 User Manual • Installation Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet (for example, 115 AC voltage for U.S. or 230 AC voltage for Europe).
Configuration and Installation 2 This chapter describes how to configure and install the NI PXI-8250. Software Installation Before installing the NI PXI-8250, install the NI System Monitor driver software. Refer to the NI System Monitor 1.1 Help for specific installation instructions. Notes It is necessary to install the NI System Monitor driver software before attempting to use the NI PXI-8250, or the system will not recognize the NI PXI-8250 and you will be unable to configure or use the device.
Chapter 2 Configuration and Installation The NI PXI-8250 is a sensitive electronic device shipped in an antistatic bag. Open only at an approved workstation and observe precautions for handling electrostatic-sensitive devices. Install the NI PXI-8250 in only the right-most slot of an NI PXI-1042/1042Q or NI PXI-1045. As such, the NI PXI-8250 should only be installed in slot 8 of an NI PXI-1042/1042Q chassis or slot 18 of an NI PXI-1045 chassis.

Touch a metal part on the chassis to discharge any static electricity that might be on your clothes or body. Static electricity can damage the hardware. 4. Insert the NI PXI-8250 module into the rightmost slot of an NI PXI-1042/1042Q or NI PXI-1045.
Chapter 2 9. Configuration and Installation Allow the operating system to properly detect and identify the NI PXI-8250 module. 10. Launch Windows Device Manager and refresh the view. The NI PXI-8250 module should be visible in Windows Device Manager. NI PXI-8250 Configuration The NI PXI-8250 module is fully compatible with the industry standard PXI Specification, Revision 2.2, and the PCI Local Bus Specification, Revision 3.0, respectively.

Chapter 3 Hardware Overview System Monitoring Architecture With the NI PXI-8250, you can simultaneously monitor intake temperature, fan speeds, and power supply levels of your NI PXI chassis. This information allows the user to achieve a higher level of system performance reliability. Once the first set of data is processed, these status parameters will also light up the top six LEDs on the front panel.
Chapter 3 Hardware Overview Fan Monitoring The NI PXI-8250 module allows the user to monitor the revolutions per minute (RPM) of all rear-facing fans of a PXI chassis (two fans in an NI PXI-1042/1042Q and three fans in an NI PXI-1045), accurate to ±50 RPM. The fan data from the chassis is interpreted by the NI PXI-8250 and the FAN front panel LED reflects the status of all of the fans collectively together.
Chapter 3 Hardware Overview System Status LEDs There are 6 system status LEDs to report the status of the +5 V, +3.3 V, +12 V, and –12 V power rails, the intake temperature of the chassis, and the overall status of the power shuttle fans of the chassis. These LEDs only light up either red or green depending on whether the status information shows the parameters in the specified range. The criteria for the system status LEDs to light green is provided in Table 3-1.

Chapter 3 Hardware Overview Alert Relay Pins The NI PXI-8250 has an electromechanical non-latching relay with three ports: normally open (NO), normally closed (NC), and common (COM). The top three pins of the front panel connector are connected to a relay as indicated in Figure 3-5. This relay is useful for a creating a custom external warning indicator circuit, such as a factory warning light or speaker.
