Getting started
Getting started
M!DGE Wireless Router will only operate reliably over the cellular network if there is a strong signal.
For many applications a flexible stub antenna would be suitable but in some circumstances it may be
necessary to use a remote antenna with an extension cable to allow the antenna itself to be positioned
so as to provide the best possible signal reception.
1. Install the SIM card
Insert a SIM card into the SIM socket. Make sure the SIM is enabled for data transmission.
2. Connect and fit the cellular antenna
If needed, contact RACOM for suitable antennas and other details.
3. Connect the LAN cable
Connect one M!DGE Ethernet port to your computer using an Ethernet cat.5 cable.
4. Connect the power supply
Connect the power supply wires to the M!DGE screw terminals, ensuring correct polarity. Switch
on the power supply.
5. Setting of IP address of the connected computer
By default the DHCP server is enabled, thus you can allow the Dynamic Host Configuration Protocol
(DHCP) on your computer to lease an IP address from the M!DGE. Wait approximately 20 seconds
until your computer has received the parameters (IP address, subnet mask, default gateway, DNS
server).
As an alternative you can configure a static IP address on your PC (e.g. 192.168.1.2/24) so that it
is operating in the same subnet as the M!DGE. The M!DGE default IP address for the first Ethernet
interface is 192.168.1.1, the subnet mask is 255.255.255.0.
6. Start setting up using a web browser
Open a web browser such as Internet Explorer or Firefox. In the address field of the web browser,
enter default IP address of M!DGE (i.e. http://192.168.1.1); initial screen will appear. Follow the instructions and use the M!DGE Web Manager to configure the device.
Fig. 1: Cellular router M!DGE
Note
M!DGE can be safely turned off by unplugging the power supply.

M!DGE router
1. M!DGE router
1.1. Introduction
Although M!DGE wireless routers have been specifically designed for SCADA and telemetry, they are
well suited to a variety of wireless applications. M!DGE HW and SW are ready to maintain reliable and
secure connections from a virtually unlimited number of remote locations to a central server. Both
standard Ethernet/IP and serial interfaces are available. Moreover, a digital input and a digital output
can be used for direct monitoring and control of application devices; the second DI and DO are available
using an extension module.
M!DGE versatility is further enhanced by four independent Ethernet ports. These can be configured to
either support independent LANs (e.g. LAN and WAN settings), or simply connect up to four devices
within one LAN (effectively replacing an Eth switch). M!DGE software is based on proven components,
including an Embedded Linux operating system and standard TCP/IP communication protocols.
Thanks to the compact size and versatility of M!DGE, wireless routers prove indispensable in many
SCADA and telemetry, as well as POS, ATM, lottery and security/surveillance applications.
M!DGE together with RACOM RipEX radio router offers an unrivalled solution for combining cellular
and UHF/VHF licensed radios in a single network.

Implementation notes
3. Implementation notes
3.1. Ethernet SCADA protocols
SCADA equipment with an Ethernet protocol behaves as standard Ethernet equipment from a communications perspective. Thus the communication goes transparently through the cellular network. The
implementation requires heightened caution to IP addressing and routing. NAPT functionality should
be used frequently.
3.2. Serial SCADA protocols
A SCADA serial protocol typically uses simple 8 or 16 bit addressing. The mobile network address
scheme is an IP network, where range is defined by the service provider (sometimes including individual
addresses, even in the case of a private APN). Consequently, a mechanism of translation between
SCADA and the IP addresses is required. To make matters worse, IP addresses may be assigned to
GPRS (EDGE, UMTS, etc.) devices dynamically upon each connection.
Please read application note "M!DGE/MG102i - Serial SCADA Protocols"1which describes how to efficiently solve this problem using RACOM routers.
3.3. Network center
In every network, the center plays a key role and has to be designed according to customer's requirements. Several possible solutions are described in the application note "M!DGE/MG102i - Typical us-
age"2.
3.4. VPN tunnels
Customer data security arriving through the mobile network is often very important. Private APN is the
basic security requirement, but not safe enough for such applications.
VPN tunnels solution is closely connected with the center and is also described in application note
"M!DGE/MG102i - VPN Configuration"3.

Bench test / Step-by-Step guide
5. Bench test / Step-by-Step guide
Before starting to work with the HW please be sure that you have a SIM card enabled for data and you
have all the necessary information from the mobile operator (PIN, APN, login, passwd)
5.1. Connecting the hardware
5.1.1. Install the SIM card
Insert a SIM card into the SIM socket, use the first one. Make sure the SIM is enabled for data transmission.
There are two reasons for installing the SIM card as the first task: a) the SIM card could be damaged
when inserted into the powered equipment, b) the information from SIM card are read only after a power
cycle.
5.1.2. Connect the cellular antenna
Fit a cellular antenna. For details see RACOM web1or contact RACOM for suitable antennas.
5.1.3. Connect the LAN cable
Connect one M!DGE Ethernet port to your computer using an Eth cat.5 cable.
5.1.4. Connect the power supply
Connect the power supply wires to the M!DGE screw terminals, ensuring correct polarity. Switch on
the power supply.
5.2. Powering up your wireless router
Switch on your power supply. The STAT LED flashes for a few seconds and after 8 seconds it starts
blinking to a green light. After approximately 30 seconds your router will have booted and will be ready;
the STAT LED remains shining.
When the Mobile Connection is enabled the WAN LED starts blinking while connecting to the cellular
network – the color (green/orange/red) represents the signal strength (excellent, medium, weak).
You’ll find the description of the individual LED states in Section 4.3, “Indication LEDs”.
5.3. Connecting M!DGE to a programming PC
a. Please connect the Ethernet interfaces of your computer and M!DGE.
b. If not yet enabled, please enable the Dynamic Host Configuration Protocol (DHCP) so that your
computer can lease an IP address from M!DGE. Wait a moment until your PC has received the
parameters (IP address, subnet mask, default gateway, DNS server).
Alternative: Instead of using the DHCP, configure a static IP address on your PC (e.g.
192.168.1.10 mask 255.255.255.0) so that it is operating in the same subnet as the M!DGE.

M!DGE2 GPRS/UMTS/HSPA+/LTE router – © RACOM s.r.o.26
Bench test / Step-by-Step guide
The default IP address is 192.168.1.1 for all Eth interfaces (Eth1 - Eth4), the default subnet mask
is 255.255.255.0 for all interfaces.
Default DHCP range 192.168.1.100 to 192.168.1.199
c. Start a Web Browser on your PC. Type the M!DGE IP address in the address bar:
http://192.168.1.1
d. Please set a password for the admin user account. Choose something that is both easy to remember
and a strong password (such as one that contains numbers, letters and punctuation). The password
must have a minimum length of 6 characters. It must contain a minimum of 2 numbers and 2 letters.
Note
For security reasons, there is no default password.
e. Agree to the terms and conditions. The user is now obliged to accept our end user license agreement
during the initial M!DGE setup.
f. You might check the "Configure automatic mobile data connection" for automatic WWAN configur-
ation. Manual changes are usually required afterwards. Note that Firewall is also enabled with
predefined WAN administration ports.
5.4. Basic setup
The M!DGE Web Manager can always be reached via the Ethernet interface. After successful setup,
Web Manager can also be accessed via the mobile interface. Any up to date web browser can be used.
Any web browser supporting JavaScript can be used. By default, the IP address of the 1st Ethernet
interface is 192.168.1.1, the web server runs on port 80.
The minimum configuration steps include:
1. Defining the admin password
2. Entering the PIN code for the SIM card
3. Configuring the Access Point Name (APN)
4. Starting the mobile connection
Note
Router M!DGE can be safely turned off by unplugging the power supply.

Installation
6. Installation
6.1. Mounting
M!DGE Wireless Router is designed for a DIN rail mounting or on a panel using flat bracket. Please
consider the safety instructions in Section 6.1, “Mounting”.
6.2. Antenna mounting
M!DGE Wireless Routers will only operate reliably over the cellular network if there is a strong signal.
For many applications the flexible stub antenna provided would be suitable but in some circumstances
it may be necessary to use a remote antenna with an extended cable to allow the antenna itself to be
positioned so as to provide the best possible signal reception.
Beware of the deflective effects caused by large metal surfaces (elevators, machine housings, etc.),
close meshed iron constructions and choose the antenna location accordingly. Fit the antenna or
connect the antenna cable to the ANT connector.
In external antennas the surge protection of coaxial connection would be required.
Note
Be sure that the antenna was installed according to the recommendation by the antenna producer and all parts of the antenna and antenna holder are properly fastened.
6.3. Power supply
M!DGE can be powered with an external power source capable of voltages from 9.6 to 28.8 Volts DC.
M!DGE should be powered using a certified (CSA or equivalent) power supply, which must have a
limited and SELV circuit output.

7.1. HOME
This page gives you a system overview. It helps you when initially setting up the device and also
functions as a dashboard during normal operation.
The highest priority link which has been established successfully will become the so-called hotlink
which holds the default route for outgoing packets.
Detailed information about status of each WAN interface is available in a separate window.

7.2. INTERFACES
Details for all physical connections are given in Section 4.2, “Connectors”.
7.2.1. WAN
Link Management
Each available item in the WAN Link Manager matches with the particular WAN interface. Depending
on your hardware model, WAN links can be made up of either Wireless Wide Area Network (WWAN),
Wireless LAN (WLAN), Ethernet or PPP over Ethernet (PPPoE) connections. Please note that each
WAN link has to be configured and enabled in order to appear on this page.
In case a WAN link goes down, the system will automatically switch over to the next link in order of
priority (the priorities can be changed using the arrows on the right side of the window). A link can be
either established when the switch occurs or permanently to minimize link downtime.
1st priority: This link will be used whenever possible.
2nd priority: The first fallback technology.
Up to four priorities can be used.
