- Comprehensive Connectivity: Parallel, floppy, keyboard, and mouse interfaces.
- Serial Communications: 2 or 3 asynchronous ports, 1 or 2 synchronous/asynchronous ports.
- System Monitoring: Onboard debug monitor with self-test diagnostics.
Application Scenarios
Utilized in military command systems, aerospace avionics, and medical diagnostic equipment.
Performance Parameters
- Network: Ethernet transceiver interface with 32-bit PCI local bus DMA.
- Storage: 8-bit or 16-bit fast SCSI-2 bus interface.
- Timers: Four 32-bit timers, one watchdog timer.
Material Composition
High-Tg, UL94V-0 flame-retardant PCB with high-reliability BGA components.
Structural Characteristics
6U VME single-board computer with standard front panel I/O and status indicators.
Working Principle
The system boots from flash memory, initializes the RAM200 ECC DRAM, and configures the PCI-to-VME bridge for backplane communication.
Installation Requirements
Ensure proper grounding of the VME chassis. Align connectors carefully to prevent pin damage.
Usage Precautions
Never operate the board without adequate forced-air cooling. Handle with care to avoid mechanical stress on the PMC connector.
