Electrostatic Discharge (ESD)

Qualified Personnel

The product/system described in this documentation may be operated only by

personnel qualified for the specific task in accordance with the relevant documentation,

in particular its warning notices and safety instructions. Qualified personnel are those

who, based on their training and experience, are capable of identifying risks and

avoiding potential hazards when working with these products/systems.

Computer boards and components contain electrostatic sensitive devices.

Electrostatic discharge (ESD) can damage components. To protect the PCB

and other components against damage from static electricity, follow some

precautions whenever you work on your computer.

Power down and unplug your computer system when working on the

inside.

Hold components by the edges and try not to touch the IC chips, leads,

or circuitry.

Use a grounded wrist strap before handling computer components.

Place components on a grounded antistatic pad or on the bag that came

with the component whenever the components are separated from the

system.

Only store the product in its original ESD-protected packaging. Retain

the original packaging in case you need to return the product to MEN for

repair.

Product Compliance

MEN products are no ready-made products for end users. They are tested according to

the standards given in the Technical Data and thus enable you to achieve certification of

the product according to the standards applicable in your field of application.

If the product delivered was certified by MEN and is modified by the customer, e.g., by

installing an additional hardware component, the certification achieved by MEN

becomes invalid and has to be repeated for the new product configuration.

RoHS

MEN is committed to develop and produce environmentally compatible products

according to the Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU

(formerly 2002/95/EC) of the European Union.

Since July 1, 2006 all MEN standard products comply with RoHS legislation.

REACH

MEN is a manufacturer of electronic products and thus a so-called "downstream user" in

terms of REACH. The products MEN supplies are solely non-chemical goods. Moreover

and under normal and reasonably foreseeable circumstances of application, the goods

supplied shall not release any substance.

Beyond that, according to REACH – Art.33, MEN will inform the customer immediately

should a substance contained in an MEN product (with a content of > 0.1%) be classified

alarming by the European Chemicals Agency (ECHA).

WEEE Application

Nevertheless, MEN is registered as a manufacturer in Germany. The registration number

can be provided on request.

The WEEE directive does not apply to fixed industrial plants and tools. The

compliance is the responsibility of the company which puts the product

on the market, as defined in the directive; components and sub-

assemblies are not subject to product compliance.

Since MEN does not deliver ready-made products to end users, the WEEE

directive is not applicable for MEN. Users are nevertheless recommended

to properly recycle all electronic boards which have passed their life cycle.

Product Overview

1 Product Overview

1.1 Product Description

Extension for Various Applications

The ME4 is a modular extension for embedded applications in transportation, e.g., in

trains or wayside. The module adds wireless connectivity and fieldbus and audio

functionality to the system CPU. Main applications of the module include predictive

maintenance, IoT gateway, diagnostics server, smart vehicle, passenger information and

ticketing systems.

Wireless Connectivity

The ME4 comes with one M.2 slot for high speed LTE modems (LTE Advanced or LTE)

providing two front-accessible micro-SIM card slots. For GPS/GLONASS functions, the

box has an onboard GNSS receiver which can be connected via antenna connector.

Fieldbus and Audio Functionality

The ME4 is equipped with one PCI Express Mini Card slot which is prepared for adding an

MVB, CAN bus or audio module. The functions can be made available on two D-Sub

connectors at the front panel.

Modular System for Easy Configuration

Due to MEN's modular concept, the ME4 offers flexibility in built-to-order configurations.

Via its extension connectors, the box can be easily combined with pre-fabricated 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

distribution between 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 aluminum housing with cooling fins allows fanless operation. ME4 has no moving

parts, making it maintenance free.

Rolling Stock Qualified and Long-Term Availability

The wireless and fieldbus module is qualified for rolling stock and wayside applications.

Long term availability until 2028 minimizes life-cycle management by making the ME4

available at least for this period of time.
