Ethernet devices: DDC gigabit Ethernet network card targeted for UAV avionics

The ET-71000 series from DDC in Bohemia, N.Y., are dual channel Gigabit Ethernet (GigE) PMC cards optimized for use in embedded avionics such as unmanned aerial vehicles. These include sensor interfacing, multi-processor and digital signal processor arrays, radar systems, display systems, serial backplanes, and storage. The cards include a TCP/IP Off-load Engine (TOE) that implements the full TCP/IP protocol stack, thus freeing up valuable host processor bandwidth. There are versions of the card providing either electrical or optical interfaces on a conduction cooled PMC form factor. DDC developed firmware for the TCP/IP protocol engine, data traffic manager, and redundancy manager provides deterministic performance and reliability. ET-71000 supports high-speed duplex data transfer while preserving standard driver interfaces such as VxWorks Sockets. For more information go online at www.ddc-web.com www.ddc-web.com.
