Description
GE VMIVME-5565-110000 Technical Specifications:
- Memory Capacity: 128 MBytes SDRAM.
- Fiber Type: Multi-mode optical transceivers.
- Max Distance: Up to 300 meters between nodes using multi-mode fiber.
- Bus Compatibility: Standard VME64 backplane.
- Data Integrity: Hardware CRC checking and ECC memory protection.
Functional Features:
- Cost-Effective Short-Range Networking: Multi-mode optics provide high-speed connectivity at a lower cost than single-mode for rack-to-rack or room-scale deployments.
- Seamless Integration: Fully compatible with other 5565 series nodes (PCI, PMC, PCIe) regardless of their memory size or fiber type, allowing heterogeneous network design.
- Automatic Synchronization: Guarantees that all nodes have identical data at the exact same memory location at all times.
Application Scenarios:
- Intra-cabinet redundant controller synchronization.
- Test stands where multiple simulation PCs are located within the same laboratory or facility.
- Manufacturing cells requiring sub-microsecond data sharing.
Performance Parameters:
- Continuous Transfer Rate: Up to 170 MB/s for 64-byte packets.
- Jitter: Extremely low deterministic jitter due to hardware-based routing.
- OS Independence: Transparent to the host operating system (VxWorks, Linux, Windows, QNX).
Material Composition & Structural Characteristics:
- Optical Transceivers: Integrated multi-mode SFP or fixed optical modules.
- VME Connectors: Standard DIN 41612 P1/P2 backplane connectors.
- Thermal Management: Heat sinks on the SDRAM and network controller ASICs to handle continuous high-speed data traffic.
Working Principle: Operates identically to the base VMIVME-5565 architecture, utilizing the multi-mode optical physical layer to propagate write operations across the ring. The 128MB buffer provides ample space for large dataset sharing, waveform storage, or extensive I/O mapping tables.
Installation Requirements:
- Fiber Selection: Strictly use multi-mode fiber patch cables (typically 50/125 or 62.5/125 micron) for this specific part number.
- Network Planning: Calculate total fiber length to ensure it remains under the 300-meter limit.
- Software Drivers: Install the appropriate VME RFM driver matching the 128MB memory map.
Usage Precautions:
- Mixing Fiber Types: Do not connect multi-mode ports (110000 series) directly to single-mode ports (111000 series) without appropriate media converters.
- Memory Sizing: Ensure the 128MB capacity is sufficient for the application’s shared dataset; upgrade to the 256MB (210000 series) if necessary.
- Redundancy: For critical applications, implement dual-ring redundancy or star-topology with a managed hub.
