National Instruments NI PXI-8250 Getting Started

Getting Started

This chapter includes information about the features of the NIPXI-8250

and information about operating the hardware.

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.

NI PXI-8250 can be used with an NI PXI-1042, NI PXI-1042Q, or

NIPXI-1045 chassis to detect and report chassis voltage rail problems,

out-of-range chassis intake temperature, or chassis power shuttle fan

failure. The NI PXI-8250 monitors the status of these parameters and

reports the status through a set of LEDs on the front panel of the module.

The NIPXI-825 0 also includes a relay that toggles when any of the

parameters fall outside of specification during chassis operation. These

features can be used to monitor the state of the chassis and easily identify

system failure.

The NI PXI-8250 comes with NI System Monitor software that includes the

driver for the module and an application programming interface (API) that

allows programmatic access to the information reported by the module.

Although the driver allows for proper detection of the hardware, it is not

required for the normal operation of the six system status LEDs, the

alertrelay, or the power outputs of the NI PXI-8250.

There is also a set of six user LEDs on the front panel of the NI PXI-8250

designed for custom alert configurations. This feature is not available

withNI System Monitor 1.1, and may be added in future releases of

NISystem Monitor. Refer to the NI System Monitor Help for more

information.
