The Alta Data Technologies ENET2-1553-2D is a dual-channel MIL-STD-1553 interface module that bridges 1553 communications to Ethernet networks via IP/UDP. Built on the AltaCore FPGA protocol engine, this compact appliance enables real-time remoting of 1553 operations across local area networks. It supports full Bus Controller, Remote Terminal, and Bus Monitor functionality with integrated signal capture on the first channel for cable diagnostics and cybersecurity analysis. The device operates across 10/100/1000 Mbps Ethernet and delivers UDP request/response latency typically under 10 µs from device to 1553 buffers, with IP/UDP bridging response times as fast as 20 µs. Power input ranges from 5–30 V DC with typical consumption of 300–700 mA, or optionally via IEEE 802.3af PoE (Type 1) up to +55°C ambient. The module is housed in a rugged 13.5 × 3.7 × 4 cm enclosure weighing 200 g and includes 64-bit time tags with 20 ns resolution, IRIG-B RX decode, PPS, hardware triggers, and full error injection/detection. Dual redundant (A/B) MIL-STD-1553 connections use Glenair Mighty Mouse connectors. AltaAPI supports Windows, .NET, LabVIEW, ANSI C, and Linux development without code recompilation, delivering high portability. Suitable for aerospace, defense, and industrial systems handling 100–2000 packets per second. EU and China RoHS compliant.
