Technical Specifications:

 

  • Processor: Intel Pentium M at 1.1 GHz, 1.4 GHz, or 1.8 GHz with up to 2 MB L2 cache (1.4 GHz and 1.8 GHz models), supporting 32-bit addressing and 64-bit data bus for efficient multitasking and multimedia processing.
  • Memory: Up to 1.5 GB DDR SDRAM via a single SO-DIMM slot, with optional non-volatile storage (e.g., 2 GB bootable CompactFlash or 128 GB SSD).
  • Interfaces:
    • Networking: Dual Gigabit Ethernet ports (Intel 82546EB) with optional VITA 31.1 compliance, plus a 10/100BASE-T Ethernet port on the front panel.
    • Serial: Four RS-232/422/485 ports with 16-byte FIFO buffers, supporting baud rates up to 115 kbps.
    • USB: Four USB 2.0 ports (two front-panel, two rear I/O) for peripheral integration.
    • Storage: Serial ATA (SATA) and Ultra ATA/100 IDE support for high-speed data storage.
    • Video: SVGA and DVI-I graphics outputs with dual-head display capability.
    • Expansion: One PCI-X PMC slot (66 MHz) for adding specialized modules (e.g., analog I/O, FPGA cards).
  • Power: Requires +5V DC (±5%) and ±12V DC inputs, with typical power consumption ≤12W.
  • Environmental:
    • Operating temperature: -40°C to 85°C (extended industrial range).
    • Compliance: Meets EMI/EMC standards (EN 61000-6-2/3) and withstands shock (50g) and vibration (5–500 Hz).

 

Functional Features:

 

  • Real-Time OS Support: Compatible with Windows XP, Windows 2000, VxWorks, QNX, and Linux, enabling deterministic task scheduling and low-latency control.
  • Watchdog Timer: Hardware-based reset mechanism with programmable timeout intervals to ensure system stability.
  • Remote Management: Web-based interface and SNMPv3 support for firmware updates, diagnostic monitoring, and remote configuration.
  • Data Integrity: Built-in error detection (CRC) and parity checking for memory and communication channels.
  • Expansion Flexibility: PMC slot allows integration of high-speed data acquisition cards or FPGA modules.
  • Boot Options: Supports remote Ethernet booting (PXE) and local boot from CompactFlash or SSD.

 

Application Scenarios:

 

  • Industrial Automation: Deployed in manufacturing lines for robotics coordination, conveyor systems, and process control, leveraging its real-time processing and deterministic I/O.
  • Aerospace and Defense: Used in flight simulators and avionics testing for nanosecond-level synchronization and rugged reliability.
  • Medical Imaging: Supports real-time image reconstruction in MRI/CT systems through high-bandwidth memory and PMC expansion.
  • Energy Management: Implements grid-scale monitoring in smart grids, optimizing power distribution and renewable energy integration.
  • Transportation: Integrates into railway signaling systems and autonomous vehicles for precise motion control and safety-critical operations.
