- Comprehensive I/O: Features a PC87308 Super I/O controller, Z8536 CIO device, and ESCC 85230 for extensive serial and parallel communication options.
- System Management: Includes an ABORT switch (S1), a RESET switch (S2), and six front-panel diagnostic LEDs (DS1-DS6) for real-time system monitoring and troubleshooting.
Application Scenarios
- Industrial Automation: Serves as a central controller in Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC).
- Telecommunications: Deployed in network routing, switching infrastructure, and data acquisition systems.
- Defense & Aerospace: Utilized in ruggedized military computing, radar systems, and flight simulation equipment.
Performance Parameters
- Operating Temperature: 0°C to 55°C entry air temperature with forced-air cooling.
- Storage Temperature: -40°C to +85°C for non-operating conditions.
- Humidity: 5% to 90% relative humidity (non-condensing).
- Bus Performance: Supports a 33MHz 32/64-bit PCI Local Bus and standard VMEbus arbitration.
Material Composition
Constructed using high-quality, UL-recognized printed wiring boards (PWBs) with a 94V-0 flammability rating. It incorporates industrial-grade silicon components, precision ASICs, and a sealed battery-backed NVRAM module.
Structural Characteristics
- Form Factor: Double-high 6U VME board.
- Dimensions: Base board height is 9.2 inches (233 mm) and depth is 6.3 inches (160 mm). With the front panel and connectors, the depth extends to 10.3 inches (262 mm) and height to 7.4 inches (188 mm).
- Front Panel Width: 0.8 inches (20 mm).
Working Principle
The MVME2604-3371 executes instructions via the PowerPC processor, managing system resources through the Falcon chipset and Raven ASIC. It facilitates high-speed DMA transfers across the PCI local bus and VMEbus, processes network and SCSI data, and maintains system state via the integrated NVRAM and watchdog timer.
Installation Requirements
- Electrostatic Discharge (ESD): An ESD strap must be attached to the wrist and connected to the chassis ground before handling.
- Power Down: The operating system must be properly shut down, and all AC/DC power cords must be disconnected before removing the chassis cover or inserting the module.
- Cooling: Requires adequate forced-air cooling directed across the board to maintain safe operating temperatures.
Usage Precautions
- EMI Protection: The equipment generates and radiates electromagnetic energy; it must be installed in a cabinet with adequate EMI protection to prevent interference.
- Safety Compliance: Users must strictly adhere to all safety precautions and warnings outlined in the manufacturer’s manual to ensure safe operation in the target environment.
- Hardware Configuration: Proper configuration of cache mode controls, flash bank selection, and serial port clocks via onboard jumpers is required before initial power-up.
