Embedded Network Connectivity for Modular Computer Systems

Manufacturer: duagon MEN

The ME1 is a modular extension for embedded applications in transportation, e.g., in trains, buses or commercial vehicles. The module adds wireless connectivity to the MC50M system CPU. Main applications of the module include predictive maintenance, IoT gateway, diagnostics server, smart vehicle, passenger information and ticketing systems.

Wireless Connectivity

The ME1 comes with two M.2 slots for high-speed LTE modems (LTE Advanced or LTE). For each M.2 slot, two front-accessible micro-SIM card slots are available. The PCI Express Mini Card slot is prepared for adding a WLAN module and also provides audio functions, which can be used via the optional 9-pin D-Sub connector on the front panel. For GPS/GLONASS functions, the box has an onboard GNSS receiver which can be connected via antenna connector.

Modular System for Easy Configuration

Due to MEN's modular concept, the ME1 offers flexibility in built-to-order configurations. Via its extension connectors, the box can be easily combined with prefabricated CPU modules or other extension modules, for example, a PSU or removable storage shuttles, providing additional features and short delivery times. In the modular system, the data transfer between the modules as well as the power supply of the individual components takes place via the extension connectors standardized by MEN.

Flexible System Installation

Various mounting options facilitate the integration of the box into an existing environment. The standard 35 mm DIN Rail mounting offers space-saving mounting of all system modules on a single rail. Wall mounting and mounting in a 19" rack using adaption brackets are an option.

The aluminium housing with cooling fins provides conduction cooling for fanless operation. ME1 has no moving parts, making it maintenance-free.

In-Vehicle Qualified and Long-Term Availability

The CPU module is qualified for rolling stock and wayside applications as well as for road vehicles (ECE R10). Long term availability of 15 years from product start minimizes life-cycle management by making the ME1 available at least for this period of time.
