VMIC Abaco Systems | PMC-5565PIORC-110000 | 128MB Reflective Memory Card

The VMIC PMC-5565PIORC-110000 is a high-performance 128MB reflective memory network interface card featuring multimode fiber connectivity. Designed for real-time, deterministic data sharing across distributed computer systems, this PMC (PCI Mezzanine Card) module allows multiple nodes to share a common memory space at ultra-high speeds. Any data written to the local reflective memory is instantly broadcasted via fiber optics to all other nodes on the network with near-zero software overhead, making it ideal for simulation, defense, aerospace, and industrial automation applications.

🔧 Parameter Configuration & Modification Method

Hardware configuration for the PMC-5565PIORC-110000 is managed via onboard DIP switches and jumpers that define node ID settings, interrupt routing, and network timeout options. Software configuration parameters—such as DMA transfer limits, memory mapping base addresses, and interrupt masks—are established through device drivers and configuration utilities provided for operating systems like VxWorks, Windows, or Linux. Modifications require updating the host driver configuration files and rebooting the host system to reallocate the physical memory window correctly.

🔄 Manual & Automatic Mode Selection

The reflective memory card operates entirely automatically once initialized by the host driver, performing real-time hardware-level data mirroring across the fiber-optic ring without requiring manual CPU intervention for packet formatting or network protocol handling. Manual overrides are generally limited to diagnostic loopback testing modes or forced node isolation procedures executed via administrative control software during system maintenance.
