Description
The General Electric / VMIC / Abaco Systems VMIVME-5565-010000 (commonly known as the VME-5565) is an advanced Ultra-High-Speed Fiber-Optic Reflective Memory Node Card. Designed for deterministic, low-latency real-time data sharing across distributed industrial systems, simulation platforms, and data acquisition setups, this VME module allows up to 256 independent computers, PLCs, or VME controllers to share a common memory space seamlessly.

🛠️ Operation Guidelines & Installation
Installation and chassis integration must be performed strictly by qualified industrial automation technicians or embedded systems engineers. Always lock out, isolate, and completely de-energize rack power supplies and external connections before handling the VME board to prevent electrical shock or electrostatic discharge (ESD) damage. Wear an anti-static grounding wrist strap, carefully align the module with the VME chassis card guides, seat it securely into the backplane connectors, and fasten all faceplate retention screws.
🔌 Power-Up and Power-Down Sequence
Verify that fiber-optic cables (RX/TX ports) are clean, properly seated, and free of excessive bending radii prior to system startup. Ensure that backplane power pins and slot alignments are secure. Energize the VME rack power supply to initialize the onboard memory controller and network transceiver loops. Observe the status indicators on the faceplate to confirm active link communication. For maintenance or board replacement, isolate rack power supplies safely beforehand.
📝 Product Usage Instructions
Data written to the local SDRAM on one node is automatically broadcast over the high-speed fiber-optic path to all other nodes on the network without software intervention or processor overhead. Reading and writing occur just like standard memory access. Network configuration, interrupt mapping, and error-checking parameters are managed through system software drivers tailored to supported operating systems (such as VxWorks, Linux, or Windows). Keep the control cabinet environment clean and temperature-regulated.
❓ Common Questions (Q&A)
Q: What is the primary purpose of the VMIVME-5565 reflective memory board?
A: It provides an ultra-high-speed, deterministic shared memory network allowing multiple independent computer systems or VME racks to exchange real-time data with near-zero software overhead.
Q: Does the host processor manage data broadcasting across the network?
A: No, data transfers are completely software-transparent. Any write to the local reflective memory is automatically handled by the onboard hardware controller and broadcast across the fiber ring.
Q: What type of fiber-optic connections does the board utilize?
A: It uses high-speed serial transceivers operating at 2.12 Gbaud, supporting multimode connections up to 300 meters and single-mode links up to 10 kilometers.
