The DR01-MVB Wireless-Enabled MVB Router is a powerful stand-alone high reliability MVB connected gateway router with a dedicated Linux application processor capable of independently executing Client services. This device combines the functions of a gateway computer with a HW accelerated dedicated router core. Separate processors are used for the application software and the router to improve performance and enable easier software development. The application processor
directly connects to the core router with and internal Ethernet interface. This enables independent upgrading of application layer software services without the need to touch the Layer 3 routing core software.
The small footprint DR01-MVB is ideal for upgrade programs due to its small size and support for project specific firmware adaptations. Vehicle location is based on an UDR supported high sensitivity GNSS subsystem. Two M.2
sockets are available for LTE or 5G modem integration. An integrated MVB interface enables direct connection to the train MVB for operative data serving PIS or diagnostics applications.
The rear side of the device features a replaceable end plate with board-to-board connectors enabling mixed use of systems with RJ-45 and M12 connectors, the core router system board remains the same.
The router features a soldered down GNSS subsystem with UDR GNSS for installation cases where no connection to the vehicle is available. The UDR based positioning can reliably navigate underground or in poor satellite signal
conditions.
