Abaco Systems / Ramix PMC675 Dual 100BaseFX Ethernet Controller PMC Module

The Abaco Systems / Ramix PMC675 is a dual 100BaseFX Ethernet Controller PMC Module designed for high-performance data exchange in embedded systems. It integrates two 100BaseFX Ethernet controllers with a local RISC processor and a PCI bridge system, offering a flexible solution for various data transfer requirements. This module is an evolution from the PMC665 and is built using standard protocols such as 100 Mbit Ethernet and PCI/PMC, making it compatible with common LAN infrastructure and potentially reducing direct unit costs. The onboard RISC processor provides local intelligence, enabling it to handle tasks directly, reducing the burden on the host system. This local processing capability allows for advanced features like “dual rail” access, where the module can automatically switch between physical network connections, and “fail-over” functionality for enhanced fault tolerance, a critical feature for applications that previously relied on end-of-life technologies like FDDI. Additionally, the PMC675 supports optional “embedded TCP/IP” firmware, which offloads TCP/IP processing from the host board processor to the module’s onboard co-processor. Users can also integrate application-specific functionality into the onboard firmware for tailored control.
