Interphase V/Ethernet 4207 Eagle Controller Module

The Interphase V/Ethernet 4207 Eagle Controller Module is a VMEbus LAN controller that interfaces VMEbus systems with IEEE 802.3-compatible Ethernet networks. This protocol processor eliminates LAN bottlenecks in demanding, high-traffic environments by employing a partitioned architecture that enables simultaneous, independent operation of its processing, network, and bus interface subsystems.
