Product Safety
Product Safety
Read the user manual carefully before using the product. Keep the user manual for later
reference.
Conditions for Use, Field of Application
The product is designed to function correctly in the market, application area and
environmental conditions specified in the applicable standards which are listed in the
Technical Data.
Use cases in environments exceeding the specifications in the applicable standards and
the Technical Data have to be agreed upon between MEN and the customer.

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
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.

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.

2 Getting Started
2.1 Unpacking the ME4
After unpacking, check whether there are any transport or other damages on the
system. If one of the following situations arises, have the equipment checked by service
personnel:
Liquid has penetrated into the equipment.
The equipment has been exposed to moisture.
The equipment has been dropped and damaged.
The equipment has obvious signs of breakage.
Electric Shock and Fire Hazard Caused by Damaged Device
Damaged equipment may be under dangerous voltage and can cause fire.
Damaged equipment has unpredictable behavior and characteristics.
Prevent damaged equipment from being installed and put into
operation.
Mark the damaged equipment and keep it under lock and key.
Send the equipment to repair immediately.
Damage from Condensation
When the equipment has been subjected to low temperatures or extreme
temperature variations, condensation can form on or inside the system.
Humidity causes short circuits in electric circuits and damages the system.
To avoid damages, do the following:
Store the equipment in a dry environment.
Ensure that the equipment has the same temperature as the
environment before starting it up.
Do not subject the equipment to the direct radiation of a heating device.
Wait until the equipment has dried completely or wait 12 hours before
switching on the equipment.

2.2 Configuring the Hardware
Check your hardware requirements before mounting the ME4. Modifications are difficult
or impossible to do when the ME4 is mounted.
2.2.1 Installing a Micro-SIM Card
The following steps are necessary:
»Power down your system.
»Loosen the knurled-head screw of the micro-SIM cover.
»Open the micro-SIM cover as shown in the following illustration.
MEN offers suitable accessory articles for ME4.
See the MEN website for ordering information:
www.men.de/products/me4/#ord
See Figure 1, Front interfaces on page 11 for the position of the micro-SIM card slots.
On the ME4 only micro-SIM card slots 1 and 2 are functional.

»Insert the micro-SIM card into the slot with the contacts facing the PCB.
»Firmly push the micro-SIM card into the slot until it clicks into place properly.
»To eject the micro-SIM card, push it until it springs out, then pull the card out of the
slot.
»Close the micro-SIM cover and fasten the knurled-head screw.
2.2.2 Installing In-System Devices
The following devices can be installed:
PCI Express Mini Card
M.2 Card
See the MEN website for ordering information:
www.men.de/products/me4/#ord
Opening the ME4 and installing optional components may lead to a loss of
the certification and therefore make the declaration of conformity invalid.
Please order a pre-configured ME4 at MEN!
