General

Remember to follow any special regulations and warnings in force in any area and never
use the unit whenever it’s forbidden to use it. Do not use the unit when it may cause
interference or danger. A wireless device exposed to interference above specified limits
could result in deteriorated performance.

Hospitals or other Medical environment

Do not use the unit in a medical environment such as health care facilities. Follow any
regulations or rules that instruct you to not use the unit.

Pacemakers

The Health Industry Manufacturers Association recommends that a minimum separation
of six (6”) inches be maintained between cellular wireless equipment and a pacemaker to
avoid potential interference with the pacemaker. These recommendations are consistent
with the independent research by and recommendations of-Wireless Technology
Research.

Persons with pacemakers:
… Should ALWAYS keep the the unit and its antenna more than six inches from their

pacemaker when the unit is turned ON.

… If you have any reason to suspect that interference is taking place, turn your wireless

equipment OFF immediately.

Hearing Aids

Some digital wireless equipment may interfere with some hearing aids. In the event of
such interference, you may want to consult your service provider [or call the customer
service line to discuss alternatives.]

Other Medical Devices

If you use any other personal medical device, consult the manufacturer of your device to
determine if they are adequately shielded from external RF energy.-Your physician may be
able to assist you in obtaining this information.

Turn the wireless equipment OFF in health care facilities when any regulations posted
in these areas instruct you to do so. Hospitals or health care facilities may be using
equipment that could be sensitive to external RF energy.

Aircraft

Do not use the unit in an aircraft. The use of a wireless unit in an aircraft may be
dangerous to the operation of the aircraft, disrupt the wireless network, and may be
illegal.

Failure to observe these instructions may lead to suspension or denial of cellular services
to the offender, legal action, or both.

Vehicle

If the unit is incorrectly installed in a vehicular environment, the operation of the unit
could interfere with the vehicle electronics. Faulty installation and/or operation can
constitute a safety hazard.

6623-2250

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.

Backup copies

Remember to make backup copies of all important data, for example PIN/PUK codes,
contents of SIM card etc.

Antenna care

Use only the supplied or an approved replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the unit and may violate current regulations.

Do not touch the antenna unnecessarily when the unit is in use. Contact with the
antenna affects call quality and may cause the unit to operate at a higher power level
than otherwise needed.

Maintenance

No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Description MRD-315

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-315 industrial mobile broadband
router uses the Internet to cost effectively
inter-connect systems, allowing HMI, PLCs,
sensors etc to communicate with each other.

A compact case design with DIN-rail
mounting clips and the wide power input
range between 10 to 60 VDC make the unit
well suited for industrial applications. Easy
integration with other devices is achieved
using the built-in two port Ethernet switch and the RS-232 D-sub.

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-315 offers network protection from malicious eavesdroppers via encrypted
communication tunnels (VPN), and features a simple, yet powerful, packet inspection firewall.

For solar powered applications energy efficiency is vital and the MRD-315 has a special low-power
mode to only be fully powered when needed. The built-in serial port offers a simple modem
replacement solution with the benefit of not having to reprogram or change legacy components
during an upgrade.

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-355 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-355 offers protection of transmissions from malicious
eavesdroppers via encrypted communication tunnels (VPN), and features a simple, yet powerful,

Status Indicator

The status indicator reports the health of the unit. In normal operation, the indicator will
be green, if a fault is detected either at boot-up or during normal operation the indicator
will light red. When the unit is first switched on or is reset, the indicator will first light
red, then flash red in sequence with the Network Indicator, this is normal behavior during
boot-up and does not indicate a fault. The indicator will light red or green a short time
after power is applied. If the indicator does not light when power is applied check the
power supply voltage and connections.

Network Indicator

There are network indicators one for each SIM, i.e. MRD-315 (NET), MRD-355/455
(NET1, NET2) The indicator reports the status of the connection to the network. When
powered up the indicator will be off, the indicator will then flash green whilst the unit
searches for a network, once connected to the network the indicator will light green.

Once a network connection has been established the Network Indicator reports the
level of the received RF signal as well as any network connection faults. The signal
strength is indicated by the number of green flashes of the indicator within an indicator
period. Each indicator green flash will be followed by a short off time, an extended off
time indicates the end of the indicator period. So an indicator period starts with a green
flash followed by up to 5 additional flashes, then an extended off time, the cycle will then
repeat. The maximum number of flashes in an indicator period is 6. The indicator may
be red during the extended off time following the green flashes, this indicates a network
connection fault. The indicator will flash red if a SIM card is not present and will be solid
red if the RF circuitry is restarting, network registration has failed or the RF signal level is

18

6623-2250

too low for a connection.
When the unit is first switched on, or is reset the indicator will first light red, then flash

red in sequence with the Status Indicator, this is normal behavior during boot-up and
does not indicate a fault.

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.

Getting started

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
chambered corners align.

… Slid 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.

Connecting the Antenna(s)

The unit has three antenna connectors (SMA). Please ensure that the connecting nut is
done up tightly in order to make a good connection.

Connect the 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.

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.

Accessing and Using the Web Interface

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
The recommended IP settings for the PC used to configure the MRD Router:

• IP Address: 192.168.2.100

• Netmask: 255.255.255.0

• Default Gateway: 192.168.2.200

• Primary DNS: 192.168.2.200
Note: Although it is possible to connect the MRD directly to a Local Area Network

(LAN) it is recommend that the network configuration as described in this
section is performed prior to doing so. The DHCP server of the unit is by default
disabled.

Windows PC Network Settings

The following describes how to configure the network settings of a Windows PC so that
it can access the MRD.

Note: This procedure will change the network settings of the Windows PC, if the PC is

connected to a network the connection should be removed before performing
the changes. To restore the network, settings of the PC record the current

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.

6623-2250

29

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.
