- Maximum Memory: 256 MB ECC RAM supports large datasets and complex RTOS environments.
- System Controller: Full VME arbitration and interrupt management.
- Legacy Support: Integrated keyboard, mouse, and parallel port support.
Application Scenarios
Ideal for complex distributed control systems, high-speed data acquisition, and telecommunications infrastructure.
Performance Parameters
- Memory Bandwidth: High-speed local bus with ECC protection.
- Network: Dual 10/100Base-T Ethernet.
- I/O: Multiple RS-232/422/485 serial ports.
Material Composition
High-Tg FR4 PCB with gold-plated VME connectors and industrial-grade components.
Structural Characteristics
6U VME single-board computer with comprehensive front panel I/O and diagnostic LEDs.
Working Principle
The processor boots from Flash, initializes the PCI local bus and VME bridge, and loads the OS. DMA engines handle high-speed data transfers.
Installation Requirements
Securely mount in a 6U VME chassis. Connect all required front panel cables before powering on.
Usage Precautions
Do not mix incompatible memory modules. Ensure stable backplane power rails. Handle with ESD precautions.
