The Abaco Systems / VMIC PMC-5565PIORC-110000 is a RoHS-compliant Reflective Memory PMC node card engineered for high-speed, low-latency, deterministic data sharing across distributed systems. Operating as a mezzanine interface on PCI 64-bit 66 MHz carriers, this card enables software-transparent data exchange between up to 256 network nodes with zero processor overhead, making it ideal for real-time, time-critical applications requiring consistent performance across heterogeneous platforms and operating systems.

– Key Features
• Any network node can generate interrupts to single or all nodes with a single command
• Transmit and receive FIFOs optimize host performance during peak data rates
• Improved PIO read performance with selectable memory window sizes
• Software transparency eliminates I/O overhead and host CPU burden
• Deterministic transfer rates for time-critical, safety-critical applications
• Network capacity to 256 nodes on shared reflective memory architecture
– Typical Applications
• Real-time avionics and aerospace data distribution
• Military telemetry and command networks
• Distributed industrial control and monitoring
• Multi-processor synchronization in embedded systems
• Time-deterministic sensor fusion and data aggregation
– Compatibility & Integration
Supported operating systems include Windows, Linux, VxWorks, LabVIEW RT, RTX/RTX64, and DOS. Native integration with NI VeriStand for real-time testing applications. Requires PMC/PMI carrier (Abaco P/N 2BARCBD1) as a replacement for legacy PCI-5565PIORC implementations.
