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

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.
