NLINE-EA429™ is an innovative product that provides “remoting” of ARINC operations on 10/100/1000 Ethernet IP/UDP local area networks (LAN). NLINE-EA429 is a small, low-power, rugged device that provides connectivity for 1-8 ARINC 429/575/573/717 Channels – Ideal for remoting ARINC connections for in-field applications or point-point lab usage.
Alta has combined the industry’s most advanced 32-bit ARINC FPGA protocol engine, AltaCore™, with a real-time IP/UDP thin server. The customer can implement their application with the same feature-rich application programming interface, AltaAPI™, as used with standard cards – often without even recompiling – the ultimate in code portability.
DB-26 for ARINC Signals, and USB Type-A Connector for Power-Only, Overmolded RJ-45 for Ethernet.
See Part Numbers Tab for 4 & 8 Channels Configurations, and Options such as AltaView Analyzer (-A) Extended Temp (-E), Memory Protect (-N), TX Inhibit (-I).
AltaView analyzer provides full data logging, label encode/decode, CVT displays, and TX controls. Also, capture raw signals for testing and security analysis.
