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.

6623-2211
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.

Power Indicator
The power indicator will light green when power is applied. If the indicator does not light
when power is applied then check the power supply connections.
Network Indicator
The network 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.
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 Signal Strength Indicator, this is normal behaviour
during boot-up and does not indicate a fault.
14
6623-2211
Signal Strength Indicator
The Signal Strength Indicator reports the level of the received RF signal as well as any
network connection faults that occur. 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 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 behaviour during boot-up and
does not indicate a fault.

Connecting the Antenna
The antenna connector is an SMA, an antenna may be connected directly to this connector, ensure that the connecting nut is done up tightly in order to make a good connection.
Connect the Power Supply
The MRD-330 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 modem may need to be returned for service if this occurs. The modem 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.
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 2. 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.

Enable the Wireless Connection
To complete the configuration of the wireless connection, set the ”Connection state” to
”Always connect” and click the ”Update” button to save the changes. Once the changes
have been set, the MRD-330 will initiate a connection. Normally it will take up to 30 seconds to esablish a connection. Figure 11 shows the completed wireless configuration.
Figure 11
Checking the Status of the Connection
To check the status of the connection select ”Status” from the top level menu and then
select ”Wireless” from the second level menu. The Wireless status page will be displayed
which will look similar to the one shown in figure 12. The status of the connection will
change as the modem connects to the network, first it will report ”Checking” then
”Connecting” and finally ”Connected”. To see the value changing the page will need to be
reloaded.

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 13 will be displayed.
Figure 13
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-330 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-330. 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-330 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
13 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-330 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-330
The MRD-330 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-330 as their gateway:
• If the clients have a DHCP address allocated by the MRD-330, 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-330.
