Core Features

1. Integrated PXI System Controller

   Combines CPU, memory, storage, and I/O in a 2‑slot PXI module, enabling standalone PXI systems without external PCsNI.
2. Standard PC Peripheral Connectivity

   DVI‑I, USB 2.0, Gigabit Ethernet, RS‑232, and parallel port provide full compatibility with standard peripherals and easy integration into existing workflows.
3. Real‑Time Operation Support

   Optional flash‑based RT version runs NI Real‑Time OS for deterministic control, hard real‑time I/O, and reliable long‑term operation.
4. High‑Speed PXI Data Transfer

   Up to 132 MB/s PXI bandwidth ensures fast data acquisition, signal processing, and instrument control across multiple PXI modules.
5. Rugged and Portable Design

   Compact 3U form factor, industrial temperature range, and backplane‑powered operation suit mobile, field, and industrial environmentsNI.

Applications

1. Automated Test Equipment (ATE)

   Semiconductor test, functional test of electronic assemblies, and end‑of‑line production test systems.
2. Data Acquisition and Monitoring

   High‑speed data logging, environmental monitoring, and distributed sensor systems in industrial and research settings.
3. Industrial Control and Embedded Systems

   Machine control, process monitoring, and embedded controller for real‑time machinery and automation.
4. Aerospace and Defense

   Avionics test, radar data processing, and ruggedized field test systems requiring high reliability.
5. Portable/Field Test Systems

   Compact, battery‑powered PXI systems for on‑site maintenance, vehicle diagnostics, and remote monitoring.

Usage and Maintenance

• Install in a standard 3U PXI chassis, occupying 1 system slot + 1 expansion slot.

• Power supplied exclusively via PXI backplane; ensure chassis provides ≥20 W per slot.

• Connect peripherals (monitor, keyboard, network) to front‑panel I/O before power‑on.

• For Windows: Install NI‑PXI, NI‑DAQmx, and application software (LabVIEW, etc.).

• For Real‑Time: Use NI MAX to deploy RT OS to flash and configure network settings.

• Configure BIOS (access via front‑panel reset during boot) for boot order and hardware settings.

• Operating temperature: 0 °C to 55 °C. Maintain chassis airflow; avoid blocking fan vents.

• Humidity: 10%–90% RH (non‑condensing). Keep in dry, dust‑free environment.

• Clean front‑panel connectors and chassis filters quarterly (power off, use dry cloth).

• Storage issues: Check HDD/SSD health via OS tools; RT flash corruption requires OS redeployment.

• Boot failures: Verify PXI backplane power, reseat controller, or reset BIOS defaults.

• Long‑term storage: Power off and store in dry area; power on for 1 hour monthly to prevent moisture damage.

• For indoor industrial use only, altitude ≤2000 m, pollution degree 2.

• Dispose of electronic waste per local regulations; do not discard in general trash.
