Description

Remote access removes boundaries, eliminates the need for time consuming site visits and provide a network infrastructure suitable for today’s “always-on” society.
The MRD-455-NA industrial mobile broadband 3G/4G LTE router uses the Internet to cost effectively inter-connect systems, allowing HMI, PLCs, sensors etc to communicate with each other.

A compact design bundled with all interfaces and LEDs in the front make the unit extremely well suited for industrial applications. With isolation between the PSU and the Ethernet and serial ports the MRD-455-NA protects against issues caused by ground loops.
The dual SIM support in the device ensures that site connectivity is not dependent on a single carrier, should something happen the unit just switches to the other SIM.
Devices connected to the Internet require countermeasures towards cyber threats. The MRD-455-NA offers protection of transmissions from malicious eavesdroppers via encrypted communication tunnels (VPN), and features a simple, yet powerful, packet inspection firewall.
The MRD-455-NA with its built-in serial port offers a simple modem replacement solution with the benefit of not having to reprogram or change any other component.

Hardware Overview

Connector Pinout
Ethernet
The Ethernet ports are on the front of the unit and are marked LAN 1 and LAN 2, each port has a LED indicating the connection speed and a LED indicating activity as shown in figure below. Both ports are capable of auto-negotiation, meaning cross-over cables are not required. The Ethernet ports are switched, allowing more than one Ethernet device to be connected to the unit at one time

Mounting
The MRD-455-NA should be mounted on 35 mm DIN-rail, which is horizontally mounted inside an apparatus cabinet or similar. Snap on mounting, see figure.
Mount the MRD-455-NA with integrated DIN-clip:

Earth connection
For correct function, the ground connection on the unit needs to be properly connected to a solid ground.
See figure.

Cooling
This unit uses convection cooling.
Avoid obstructing the airflow around the unit. Spacing is recommended for the use of unit in full operating temperature range and service life.

The router should be mounted in a clean and dry location, protected from water, excessive dust, corrosive fumes, extremes of temperature and direct sunlight.

Getting started

All configuration of the MRD can be done via the web interface. In order to view the web pages a computer with a fixed IP address, on the same sub-net as the MRD, will need to be connected to one of the LAN ports.
The default IP settings of the MRD are:
IP Address: 192.168.2.200
Netmask: 255.255.255.0
Note: The DHCP server of the unit is by default disabled.
Accessing the MRD

• Open a web browser on the PC and browse to http://192.168.2.200 (the default MRD, IP address) .
• A login box will popup. If the box fails to display, re-check the cable connections to the unit and the IP address settings of the PC.

Enter the following login details:

• User Name: admin
• Password: westermo
• The Status summary page will be displayed.

Installing the SIM Card

• To eject the SIM card drawer, press the SIM card eject button using a suitable tool and remove the drawer, refer to figure for the location of the SIM card eject button.
• Insert the SIM card into the SIM card drawer with the contacts facing up, let chamfered corners align.
• Slide the drawer back into the unit ensuring that it locks into place.

Note: Before removing or inserting the SIM card, ensure that the power has been turned off and the power connector has been removed from the MRD.
Antenna(s)
The units have three antenna connectors (SMA). Please ensure that the connecting nut is done up tightly in order to make a good connection.|
Power Supply
The MRD requires a DC power source in the voltage range of 10 to 60 VDC. The unit is designed to self protect from permanent damage if the voltage exceeds 60 VDC or if reverse polarity is applied. The router may need to be returned for service if this occurs. The router can also be damaged if there is any potential difference between the chassisground, RS-232 signal ground, power (–) input, or antenna shield. Before connecting any wiring, ensure all components are earthed to a common ground point. An external isolator will be required if a positive earth power supply is used.
Factory Default Reset Switch
The reset switch is used to restore the configuration of the MRD to factory default settings. The switch is accessed through a small hole on the rear of the unit adjacent to the power connector.
To reset the configuration:

• Power down the unit.
• Use a suitable tool and depress the reset switch.
• Power up the unit ensuring the switch remains depressed for approximately 10 seconds after power is applied. The STS LED and NET LED will flash twice to indicate a reset.
• The router will now re-boot as normal with the factory default settings.

Note: Using the Factory Default Reset Switch will erase all existing configuration settings and restore the factory default settings. This includes the network connection profile settings APN, user name and password.

Dimensions
Measurements are stated in millimeters.
