Original Press Release:



Dual Channel Fast Ethernet PMC Adaptor



January 2003 - Concurrent Technologies has announced the release of the latest addition to its range of networking PMC mezzanine cards - the CL PMC/551, a two channel Fast Ethernet adaptor with 10Base-T and 100Base-TX capability. The adaptor is targeted at applications that will benefit from reducing the CPU's Ethernet
processing load while maintaining low system latency.

The improved networking performance of the CL PMC/551 is achieved through the use of two Intel® 82551QM Fast Ethernet controllers. These controllers, which have 3Kbyte FIFOs and can operate full-duplex, enable the CL PMC/551 to exhibit improved performance by offloading the TCP, UDP and IP checksums and include support for TCP segmentation offload for operations such as Large Send. The controllers also have improved Bit Error Rate performance and improved dynamic transmit chaining with multiple priorities transmit queues.

The CL PMC/551 is a single-size card and is compliant with the CMC (Common Mezzanine Card) specification. The adaptor complies with the PCI specification, features 3.3 or 5 Volt signaling, 32-bit transfers, operates at 33MHz and has bus master capability. In addition, base address and interrupt selection is software
configurable. A boot EPROM socket is also provided. The adaptor's physical connection to an Ethernet network is through industry standard RJ45 connectors that allow connection to low cost CAT 5 cabling.

This board can be used with Concurrent Technologies' CompactPCI®, VME, Multibus II, or with any other PMC compliant host board. Operating systems supported include Windows NT®, Windows® 2000, Windows® XP, Windows® XP Embedded, VxWorks®, Linux® and UnixWare®.
