FREMONT, Calif. – Elma Electronic Inc. in Fremont, Calif., is introducing an EN 50155-compliant NetSys-5304 rugged fanless embedded data router for use in harsh-environment applications like railways and transportation.

The rugged router facilitates seamless, secure communications in rolling-stock applications that involve vehicle positioning, monitoring, speed control, and collision avoidance.

The NetSys-5304 is part of Elma's Cisco-enabled family of rugged systems designed for high performance communication and computing at the network edge.

Designed to deliver secure IP-based data to mobile rail and transportation applications, the NetSys-5304 is based on Cisco's 5915 Embedded Services Router (ESR) with Advanced Enterprise IOS and Mobile Ready Net capabilities. An on-board hardware encryption engine ensures secure, uninterrupted handling of all data, video and voice.

This Cisco 5915 embedded services router (ESR) system is designed to meet EN50155 and delivers secure IP based data to mobile applications in the rail transportation industry as well as other harsh-environment applications.

Layer 3 routing protocols establish ad-hoc networks as nodes shift relative to positioning in and out of the range of fixed networks.

The NetSys-5304 also includes radio-aware routing, quality of service (QoS) support, and a dynamic link exchange protocol. These routing optimization protocols ensure sufficient bandwidth to critical wireless nodes in the time and sequence necessary to support network communication requirements.

The NetSys-5304 features a fanless design that provides passive conduction-cooling and reduces maintenance needs as well as possible component failures.

The M12 connectors and an IP67 rating enable the system to withstand severe environmental conditions like intense shock, vibration, and humidity typically found in rugged mobile applications.

The unit comes with front LEDs to verify system status as well as link activity. For more information contact Elma online at
