1 Introduction
Thank you for purchasing MG101/102 Wireless Router from Racom. This chapter gives you an introduction to
MG101/102 Wireless Router. The following chapters describe the installation and the configuration.
1.1 Safety Instructions
The MG101/102 Wireless Router must be used in compliance with any and all applicable international and
national laws and in compliance with any special restrictions regulating the utilization of the communication
module in prescribed applications and environments.
To prevent possible injury to health and damage to appliances and to ensure that all the relevant provisions
have been complied with, use only the original accessories. Unauthorized modifications or utilization of ac-
cessories that have not been approved may result in the termination of the validity of the guarantee.
The MG101/102 Wireless Routers must not be opened. Only the replacement of the SIM card is permitted.
Voltage at all connectors of the communication module is limited to SELV (Safety Extra Low Voltage) and
must not be exceeded.
For use with certified (CSA or equivalent) power supply, which must have a limited and SELV circuit output.
The MG101/102 is designed for indoor use only. Do not expose the communication module to extreme am-
bient conditions. Protect the communication module against dust, moisture and high temperature.
We remind the users of the duty to observe the restrictions concerning the utilization of radio devices at pet-
rol stations, in chemical plants or in the course of blasting works in which explosives are used. Switch off the
communication module when traveling by plane.
When using the communication module in close proximity of personal medical devices, such as cardiac
pacemakers or hearing aids, you must proceed with heightened caution.
If it is in the proximity of TV sets, radio receivers and personal computers, MG101/102 Wireless Router may
cause interference.
It is recommended that you should create an approximate copy or backup of all the important settings that
are stored in the memory of the device.
You must not work at the antenna installation during a lightning.
Always keep a distance bigger than 40cm from the antenna in order to reduce your exposure to electromag-
netic fields below the legal limits. This distance applies to Lambda/4 and Lambda/2 antennas. Bigger dis-
tances apply for antennas with higher gain.
Adhere to the instructions documented in this user’s manual.

2 Installation
2.1 Environmental Conditions
The following precaution must be taken before installing MG101/102:
Avoid direct solar radiation.
•Protect the device from humidity, steam and aggressive fluids
•Grant sufficient circulation of air around MG101/102.
•For indoor use only
•Temperature range MG102-1xN: -20 °C to +70 °C
•Temperature range MG102-2xx: -20 °C to +65 °C
•Temperature range MG101-1NN: 0 °C to +55 °C
•Humidity: 0 to 95% (non condensing)
•Altitude up to 4000m
•Mains Voltage Ripple less than ±10% of the nominal voltage
•Overvoltage Category: II
•Pollution Degree: 2
2.2 Installation of the Router
MG101/102 is designed for mounting to a panel using through holes or to be put on a worktop. Please consider the
safety instructions (chapter 1.1) and the environmental conditions (chapter 2.1).
2.2.1 Installation of the SIM Card(s)
The router incorporates two separate SIM card sockets so that if your application demands it, you may install SIM cards
for two different networks. If you only use one SIM card insert it in SIM socket 1. Make sure the SIM is suitable for
data transmission.
2.2.2 Installation of the UMTS/GSM Antenna
MG101/102 Wireless Routers will only operate reliably over the GSM network if there is a good signal. For many ap-
plications the flexible stub antenna provided will be suitable but in some circumstances it may be necessary to use a re-
mote antenna with an extended cable to allow the antenna itself to be positioned to provide the best possible signal re-
ception. MG102 can supply a range of suitable antennas.
Consider the effects caused by Faraday cages such as large metal surfaces (elevators, machine housings, etc.), close
meshed iron constructions.
Fit the antenna or connect the antenna cable to the GSM antenna connector.
2.2.3 Installation of the GPS Antenna
Use active GPS antennas for best signal reception.
2.2.4 Installation of the Local Area Network
Up to four Ethernet devices can directly be connected to the MG101/102.
2.2.5 Installation of the Power Supply
MG101/102 can be powered with the included power supply or another external source supplying between 9
and 32 Volts DC (9-28 Volts DC MG101-1NN). MG101/102 is for use with certified (CSA or equivalent) power
supply, which must have a limited and SELV circuit output.

3 Configuration
MG101/102 holds different configurations, such as the factory configuration and the user configuration. The
user configuration can be modified by the user as follows:
•Using the forms on the web pages of Web Manager (chapter 3.1)
•Upload a new configuration file using the Web Manager (chapter 3.2)
•Using the MG101/102 Command Line Interface (chapter 3.3)
If you are new to MG101/102 we recommend configuring it using the MG101/102 Web Manager. For batch
configuration upload configuration files.
3.1 Configuration via the MG101/102 Web Manager
The MG101/102 Web Manager can always be reached via the Ethernet interface. After the successful setup
the Web Manager can also be accessed via the mobile interface. Any up to date web browser may be used.
By default the IP address of the Ethernet interface is 192.168.1.1, the webserver runs on port 80.

3.1.1 Initial Access to the Web Manager
Step Description
1.
Please connect the Ethernet interfaces of your computer and the MG101/102.
2.
If not yet enabled, please enable the Dynamic Host Configuration Protocol (DHCP) so that
your computer can lease an IP address from MG101/102. Wait a moment until your PC has
received the parameters (IP address, subnet mask, default gateway, DNS server).
How to do using Windows XP:
Start > Connect To > Show all connections > Local Area Connection > Right Click > Properties >
Internet Protocol (TCP/IP) > Properties > Obtain an IP address automatically.
Alternative:
Instead of using the DHCP, configure a static IP address on your PC (e.g. 192.168.1.100) so that it is
operating in the same subnet as the MG101/102.
The factory default IP address is 192.168.1.1 The default subnet mask is 255.255.255.0.
3.
Start a Web Browser on your PC.
Type the MG101/102 IP address in the address bar:
(e.g. http://192.168.1.1)
4.
Follow the instructions of the Web Manager to configure the device.
