L-3 / Titan / VisiCom Antares MIL-1397 VMEbus Interface Board (E Mezzanine Board)

The L-3 / Titan / VisiCom Antares MIL-1397 is a VMEbus interface board equipped with an E mezzanine card, engineered to enable MIL-STD-1397E (NATO Serial) communications in military and aerospace systems. This mezzanine-based architecture provides modular flexibility for integrating serial data protocols into VMEbus embedded systems while maintaining compatibility with naval and tactical data networks. The board processes dual 16-bit input channels and delivers 32 bits of output, supporting the full range of VMEbus data transfer widths: 8, 16, 32, and 64 bits with asynchronous protocols.
