GE VMIVME‑5565 VMEbus Fiber‑Optic Reflective Memory Module

The VMIVME‑5565 is a 6U VMEbus reflective memory node card from GE VMIC (Abaco Systems). It provides deterministic fiber‑optic shared‑memory networking, replicating local memory data across up to 256 network nodes with ultra‑low latency for distributed real‑time embedded control systems.

This board features LC multi‑mode fiber interfaces, supports DMA data transfer without heavy CPU occupancy, and offers optional redundant transmission, CRC error checking and network interrupt functions. It is powered through the VME backplane and fits standard VME racks, widely used in simulation, test‑bench and industrial real‑time control cabinets.

Support DMA block transmission to move large‑volume real‑time data with minimal CPU resource consumption.
Provide programmable point‑to‑point and broadcast network interrupts for node synchronization and event notification across distributed systems.
Built‑in CRC error checking and optional redundant link transmission to enhance communication reliability in complex industrial environments.
Allow mixed networking with PCI‑5565, PMC‑5565 cards, interconnecting different bus‑architecture real‑time controllers freely.
Industrial‑grade PCB design adapts to long‑term continuous operation in real‑time simulation and heavy‑duty control cabinet environments.
