United Electronic Industries (UEI), a developer of control, test, monitoring and verification solutions, explains how TSN adapters and bridges help legacy aerospace and defense equipment work with modern Ethernet-based digital networks. Read more >>
Transitioning to a Time-Sensitive Networking (TSN) digital backbone is a crucial stage in modernizing aerospace and defense systems. This evolution is enabled through the use of TSN adapters and bridges, which integrate legacy interfaces such as ARINC-429, MIL-STD-1553, RS422/485, Digital and Analog I/O, and CAN bus into Ethernet networks.
By connecting existing subsystems to a modern, deterministic network architecture, these solutions eliminate the need for complete redesigns, preserving investment, maintaining functionality, and enabling scalable upgrades.
Beyond just streaming legacy protocols over TSN, these technologies deliver interoperability, increased bandwidth, and timing control. The ability to bridge TSN with diverse systems supports real-time, high-precision operations, synchronized data exchange, and sensor fusion. These capabilities are vital in aerospace platforms where flight operations and mission systems data must be reliably switched or separated.
Adopting TSN enables the replacement of complex network configurations with a unified, high-performance modular backbone, simplifying wiring and improving system resilience.
UEI TSN Solutions
UEI’s TSN technologies address this evolution through compliance with profiles such as IEEE 802.1DP, 802.1DG, 802.1BA, and IEC 60802.
The company’s TSN adapters and bridges enable seamless integration, portability, and reusability across current and future aircraft fleets, increasing lifetime value. UEI has a wide range of I/O options for modern avionics applications, supporting advanced and enhanced sensor fusion as systems evolve.
UEI’s solutions also facilitate modeling, configuration, and deployment, reducing integration hurdles and allowing designs developed on UEI hardware to transition directly to field use without modification.
UEI has a variety of right-sized chassis and low-power system options, delivering ad-hoc processing and distributed access to networked data. This supports platforms that operate in constrained environments and require agility, dependability, and processing power.
Webinar
UEI is running a webinar called ‘Time-Sensitive Networking — What, How, and Why It Works’ on Thursday, October 30, 2025, at 11:00 a.m. EST, exploring how TSN is transforming aerospace and ground-based control networks. Register here >>
