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 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 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.
