Overview:

The ETN-304E card is designed for use in both TTC’S Airborne Instrumentation Multiplexer (AIM) and High-Speed Avionics Data Acquisition Unit (HSAVDAU) products. The ETN-304E card provides four IEEE 802.3 Ethernet interfaces each capable of operation at 10/100BASE-T line rate speeds. The four 10/100BASE-T Ethernet interfaces are accessible at the ETN-304E faceplate via four 9-pin Dsubminiature receptacles. Each 9-pin connector corresponds to a single independent Ethernet interface. The ETN-302 interfaces directly to a custom CompactPCI like highspeed bus. Each interface is designed to allow for intelligent packet filtering and acquisition with minimal overhead on the main processor card. This allows the ETN-304E to handle various packet types in a very flexible manner. In general, the ETN-304E supports programmable filtering of any packet in the first 128 bytes of the frame header.
