The Alta Data Technologies ENET2-1553-1F is a dual-channel MIL-STD-1553 interface module that remotes 1553 bus operations over standard IP/UDP Ethernet networks. It integrates Alta’s AltaCore™ 32-bit FPGA protocol engine with a real-time IP/UDP server, enabling seamless connectivity for aerospace and defense applications. The module supports full Bus Controller, Remote Terminal, and Bus Monitor functionality across MIL-STD-1553A/B standards, including MIL-STD-1760 startup sequences.
