NM50 Mobile Gateway & WLAN Access Point
NM50 Mobile Gateway & WLAN Access Point
Maintenance Free and Extremely Rugged
The NM50 is a fanless and maintenance-free wireless access point, specifically designed
for use in railway cars and automotive applications operating in rugged environmental
conditions.
High Speed Internet and OpenWrt Firmware
The NM50 Access Point can support up to two WLAN modules, and provides reliable high
speed internet and local data connection to multiple WLAN compatible devices. A
configurable firewall protects WLAN clients and supports secure and uninterrupted
internet data access. The full-featured and modifiable firmware OpenWrt, allows easy
configuration of features.
High Performance Processor
The NM50 Access Point is based on QorIQ Power PC CPU technology from NXP. The
system is designed for fanless operation in temperatures ranging from -40 to +70°C
(+85°C for up to 10 minutes). Its special aluminum housing with cooling fins serves as a
heatsink for the internal electronics, and in this way provides conduction cooling. As a
member of the MEN family of extremely rugged industrial box PCs, the NM50 provides
the same flexibility and scalability, as well as a look and feel which is common to the
family.
Extended Coverage and Service Availability
A redundant upstream connection to a local server, or downstream to other access
points, to extend coverage and increase availability of service, is achieved via the two
Gigabit Ethernet ports available on 8-pin M12 connectors.
Compliant to Railway and Automotive Standards
The voltage supply for the fully configured NM50 Access Point is designed for maximum
flexibility and supports wide range input supply voltages from 14.4 to 154 VDC, and
meets all EN 50155 requirements for voltages ranging from 24 to 110 VDC. It is also fully
compliant to ISO 7637-2 (E-mark for automotive) standard.
Adaptable to Specific Application Needs
The NM50 comes in two standard versions and can be adapted to meet specification
application needs. Some of the most important configuration options include the
number of WLAN radios and type of upstream link.

Product Safety
Product Safety
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the
board and other components against damage from static electricity, you
should 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 board in its original ESD-protected packaging. Retain the
original packaging in case you need to return the board to MEN for
repair.

Conformity
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.
RoHS
Since July 1, 2006 all MEN standard products comply with RoHS legislation.
Since January 2005 the SMD and manual soldering processes at MEN have already been
completely lead-free. Between June 2004 and June 30, 2006 MEN’s selected component
suppliers have changed delivery to RoHS-compliant parts. During this period any change
and status was traceable through the MEN ERP system and the boards gradually became
RoHS-compliant.
WEEE Application
Nevertheless, MEN is registered as a manufacturer in Germany. The registration number
can be provided on request.
Copyright © 2015 MEN Mikro Elektronik GmbH. All rights reserved.
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.
In other words: 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.
