For Vehicles equipped with an airbag
An air bag inflates with great force. DO NOT place objects, including either installed or
portable wireless equipment, in the area over the air bag or in the air bag deployment
area. If in-vehicle wireless equipment is improperly installed and the air bag inflates,
serious injury could result.
Blasting areas
Do not use the unit where blasting is in progress or in “blasting areas”. Observe
restrictions and follow any regulation or rules.
Explosive atmospheres
Do not use the unit in any area with a potentially explosive atmosphere. Potentially
explosive areas are often, but not always, clearly marked. They include fuelling areas such
as petrol stations, below decks on boats, fuel or chemical transfer or storage facilities,
and areas where the air contains chemicals or particles, such as grain, dust, or metal
powder.
RF energy
The unit is a low power radio transmitter and receiver. When it is ON, it receives
and also sends out radio frequency (RF) signals. Most modern electronic equipment is
shielded from RF signals. However, certain electronic equipment may not be shielded
against the RF signals from the wireless unit. All radio-transmitting devices send signals,
which may cause interference in different electronic devices. To avoid interference, place
the units antenna a sufficiently long distance from other electronics.
Critical applications
Cellular units operate using radio signals and cellular networks cannot be guaranteed to
connect in all conditions. Therefore you should never rely solely on a wireless device for
essential communications, for example medical emergencies.

Description
Remote access removes boundaries, eliminates the
need for time consuming site visits and provides a
network infrastructure suitable for today’s “always-on”
society. The MRD-305-DIN industrial M2M/3G gateway/
router uses the Internet to cost effectively interconnect systems, allowing HMI, PLCs, sensors etc to
communicate with each other.
A compact case design with a power input range
between 10 to 36 VDC make the unit well suited for
industrial applications. Easy integration with other
devices is achieved using the built-in two port Ethernet
switch.
The stability of mobile connections can be affected by
various different parameters and in order to ensure
constant connectivity the MRD-series features a
connection manager.
The MRD-305-DIN offers network protection from malicious eavesdroppers via
encrypted communication tunnels (VPN), and features a simple, yet powerful, packet
inspection firewall.
The requirements and needs vary between different types of M2M applications.
Sometimes all that is needed is a reliable gateway to the internet as all the intelligence
may be located in other devices in the system. Whereas other applications might have
simpler devices that need to be securely connected to each other, or a server, via a VPN.
Regardless of which type of M2M application you might have the MRD-305-DIN from
Westermo can fulfill your communication needs. The unit works very well with any type
of SIM card, such as static IP SIM, M2M SIM, or an off-the-shelf SIM in both packet mode
or circuit switched data (CSD) mode.
Configuring the unit is very easy with the built-in web-interface, no need for special
AT-commands or similar. The device can also provide both management and monitoring
via SMS, for example an SMS could be sent to start a VPN.

Connecting the Antenna(s)
The unit has one antenna connector (SMA). Please ensure that the connecting nut is
done up tightly in order to make a good connection.
Connect the Power Supply
Connect the Power Supply The MRD requires a DC power source in the voltage
range of 10 to 36 VDC. The unit is designed to self protect from permanent damage if
the voltage exceeds 36 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, 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.
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 autonegotiation, 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.

Configure the LAN interface and DHCP Server
To access the configuration page for the LAN interface and DHCP Server, select
”Interfaces” from the top level menu. A LAN interface screen similar to the one shown
in Figure 10 will be displayed.
Figure 10
Setting the IP Address
If it is desired to change the IP address of the LAN port, follow the steps below:
• Enter the new IP address and netmask in the ”Interface Configuration table”.
• Click Update to set the changes. Once the changes have been set, the IP address of
the MRD will change. Enter the new address in the browser on the PC. It will be
necessary to login again, following the procedure described in the previous section.
Enabling DHCP
The DHCP server allows clients on the local network to be automatically allocated IP
addresses from the MRD. The unit will also provide the clients with network settings
like their default route and DNS servers. By default the DHCP server is disabled but if
enabled it will be configured to serve IP addresses in the range 192.168.2.210 through
192.168.2.240, and the Default and Maximum lease times have been set to 1440 minutes.
So if these values are consistent with the network that the MRD is connected to, then
the DHCP can be enabled by setting the Enabled field to Yes and clicking the Update
button.
If the standard settings are not applicable for the connected network, then refer to
Figure 10 and follow the steps below, to configure the DHCP server:
• Choose a group of available IP addresses on the local network. For example, if the IP
address of the MRD-355 is 192.168.2.200 with a netmask of 255.255.255.0, a group
chosen could be’192.168.2.100 to 192.168.2.150. This will provide 51 addresses for
clients.

Under the ”DHCP Server Configuration table”:
• Set the ”Enabled” option to ”Yes”.
• Enter the first address of the group in the ”Start Address box”.
• Enter the last address of the group in the ”End Address box”.
• Enter a lease time for the ”Default Lease time”.
• Enter a lease time for the ”Maximum Lease time”.
• Click ”Update” to set the changes.

Configure clients to use the MRD as their gateway
The MRD will act as a gateway for connections destined over the wireless interface. The
default configuration will provide Network Address Translation and firewalling to protect
clients on the local network.
To configure clients to use the MRD as their gateway:
• If the clients have a DHCP address allocated by the MRD, they will have learned the
necessary settings. No further configuration is needed.
• If clients have static IP addresses, set their default route and DNS server to the IP
address of the MRD.
