The RM675TX provides dual 10/100BaseT Ethernet controllers are combined with a local RISC processor (PPC 400 MHz 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), the RM675TX is intrinsically economical, both in terms of direct unit cost and ability to utilize commodity LAN hubs and switches. Users can add application specific functionality to the onboard firmware, migrating appropriate control into the RM675TX. The onboard RISC processor allows the RM675TX to be utilized in a wide range of applications. The most common use of this is "dual rail" access, where the choice of physical access is automatically switched by the RM675TX "failover" firmware. In the RM675TX’s simplest mode, all control can be kept in the system host with the RM675TX providing dual Ethernet access. Other options include “embedded TCP/IP” which allows the host to offload the TCP/IP host processor. Failover compatible drivers are available for the following: VxWorks®, HP-UX, Linux®, LynxOS®, QNX, Solaris® and Windows®.
