PMC675 Abaco Systems Dual 100BaseFX Ethernet Controller PMC Module

The GE Fanuc / Ramix PMC675, which replaces the PMC665, sets a new standard for high performance data exchange. Two 100BaseFX Ethernet controllers are combined with a local RISC processor (PPC@400MHz w/DDR memory) and PCI bridge system. The result is a very high performance, extremely flexible solution to a variety of data transfer requirements. Designed using standard protocols (100Mbit Ethernet and PCI/PMC), the PMC675 is intrinsically economical, both in terms of direct unit cost and ability to use commodity LAN hubs and switches. In addition, card edge PCI systems can be accommodated using a PMC239 adapter for rapid prototype and development.

Users can add application specific functionality to the on board firmware, migrating appropriate control into the PMC675.

The on board RISC processor allows the PMC675 to be used in a wide range of applications. In the simplest mode, all control can be kept in the system host with the PMC675 providing dual Ethernet access. Other options include "dual rail" access, where the choice of physical access is automatically switched by the PMC675 fail over. Our embedded TCP/IP allows the host to off-load the TCP/IP overhead to the local I/O co-processor. The on-board processor has 64 Mbytes of DRAM.
