MVB Communication Module

The D429X Communication Module is a multi-purpose MVB gateway platform with several interfaces, designed for maximal flexibility to cover a wide range of applications.

The D429X is a robust gateway platform with a powerful ARM7 CPU that can be individually programmed by the user to run application specific software. The development packet includes boot loader, real time operating system, and APIs to access all communication interfaces.

This communication module comes with an MVB interface for both ESD+ and EMD physical layers, and has MVB process and message data capabilities. Various CAN, RS485, RS422 and RS422 interface options are available as needed to support specific protocols and a serial command line interface can be used for application or diagnostic purposes.

The D429X is designed for the harsh traction and rolling stock environments and is fully compliant to EN 50155.
