IC695RMX128 Redundant Memory Xchange Module

Overview

The PACSystems Redundancy Memory Xchange (RMX) Module* functions as a node on a reflective memory network or as a dedicated link between CPUs in an RX3i Hot Standby CPU Redundancy system. It operates similarly to the IC695CMX128 module when not used in a redundancy system. Each network node can be any compatible reflective memory device. Data written to one node is automatically updated across all nodes in the network.

Features

• PACSystems RX3i Single Slot Form Factor: Fits seamlessly into the RX3i system architecture.
• 128 Mbytes Reflective Memory: Ensures ample memory capacity for data sharing.
• Software Configuration: All node parameters are configurable via software, eliminating the need for jumper or switch settings.
• High-speed Fiber-optic Network: Operates at 2.12 Gbaud for fast and efficient data transfer.
• No RX3i CPU Processing Required: The network operates independently of the RX3i CPU.
• Compatibility with VMIC 5565 Family: Network-compatible with RX7i CMX/RMX modules when not used in a redundant pair.
• Long-distance Connectivity: Supports single-mode fiber connections up to 10 km (6.2 miles).
• Dynamic Packet Sizes: Adjustable from 4 to 68 bytes, controlled by the RMX module.
• Programmable Module Interrupt Output: Allows for customized network interrupts.
• Error Detection and Redundant Transfer Mode: Enhances network reliability and reduces data packet loss.
• Configurable Network Memory Offset: Enables node grouping based on network address space.

Specifications
