westermo MRD-455-NA Cellular Router User Guide
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 chassis-
ground, 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.
