Working Principle The controller boots Windows from internal storage. It communicates with all PXI modules through the backplane PCI Express bus. Test programs call NI-VISA or LabVIEW drivers to configure instruments, read waveforms, and output signals. Front ports connect external peripherals. Forced air from the chassis flows across the controller to maintain operating temperature.
Installation Requirements
- Insert into PXI chassis controller slot with power off
- Connect monitor, keyboard, mouse, and LAN cable
- Rack mount chassis with ventilation clearance
- Temperature 0 °C to +55 °C
- Install NI driver software and test application
- Chassis ground connection
- Ensure front fan intake is unobstructed
Precautions
- Power off chassis before inserting or removing controller
- Do not block fan airflow
- ESD precautions during handling
- Periodically clean fan filter
- Back up system image regularly
- Store spare in anti-static packaging
- Avoid dropping or shocking the hard drive
- Verify all instrument modules are recognized in NI-MAX after boot
