1. Quick guide
M!DGE3 is a widely configurable and compact cellular router. All you have to do to put it into operation
is to connect it to an antenna and a power supply and configure it using a PC (tablet, smartphone) and
a web browser.
Fig. 1.1: Connecting M!DGE3 to a PC over WiFi, ETH/USB adapter, ETH interface
Default password for "admin" account is "admin". Change the password before deploying unit
to a network.
To configure M!DGE3 you can connect it to your PC in three ways:
PC (tablet, smartphone) connected via WiFi adapter
External WiFi adapter Part No. OTH-USB/WIFI-W2 (an optional accessory of the M!DGE3 see
ETH/USB adapter1) needs to be used. Any other adapter will not work correctly when connected
to M!DGE3 unit. Connect your PC, tablet or smartphone to M!DGE3 WiFi AP first. Its default SSID
is M!DGE3 S/N. By default, the WPA2 PSK is disabled, so no password is required. The WiFi adapter
contains a built-in DHCP server, so if you have a DHCP client in your PC (as most users do), you
do not need to set anything up. The default IP address of M!DGE3 unit, for access over the ETH/USB
adapter, is 10.9.8.7.

Quick guide

PC connected via ETH/USB adapter
External ETH/USB adapter Part No. OTH-USB/ETH-XR (an optional accessory of the M!DGE3 see
ETH/USB adapter2). The ETH/USB contains a built-in DHCP server, so if you have a DHCP client
in your PC as most users, you do not need to set anything up. The default IP address of M!DGE3
unit, for access over the ETH/USB adapter, is 10.9.8.7.
PC connected directly to an ETH port
The default IP address for access via ETH ports is 192.168.169.169.
Set a static IP address in PC to 192.168.169.0/24 (e.g.192.168.169.250, subnet mask
255.255.255.0).
Important
When you change the M!DGE3 ETH address to a different IP address/mask, the IP address
of your PC might be necessary to be updated to match the same subnet (mask).
Note
https - For security reasons the http protocol with ssl encryption can be used for the commu-
nication between the PC and M!DGE3. The https protocol requires a security certificate. You
must install this certificate into your web browser. The first time you connect to the M!DGE3,
your computer will ask you for authorisation to import the certificate into your computer. The
certificate is signed by the certification authority RACOM s.r.o. It meets all security regulations
and you need not to be concerned about importing it into your computer. Confirm the import
with all warnings and exceptions that your browser may display during installation.
Note
If you do not have the USB adapter or you have forgotten the password, you can reset the
access parameters to defaults, see Section 2.2.8, “HW button”.

2. Product
M!DGE3 is a cellular router platform designed for any real-time environment. M!DGE3 cellular routers
are native IP devices, with Linux OS that have been designed with attention to detail, performance and
quality.
M!DGE3 is built into a rugged metal casing that allows for multiple installation possibilities, see Sec-
tion 4.1, “Mounting”.

2.2. Connectors
All connectors are located on the front and bottom panel. The front panel contains even LEDs. The
HW button is located on the front panel as well (close to the upper edge).

2.2.1. Antenna
Fig. 2.5: Antenna connectors
An antenna can be connected to
M!DGE3 via SMA female 50 Ω connect-
or.
M!DGE3 is equipped with two connect-
ors. The ANT1 connector will be used
for common transmitting and receiving
single antenna installation. The ANT2
connector will be used as a second
MIMO connector.
Warning
M!DGE3 cellular router may be
damaged when operated without an antenna or a dummy load.

2.2.2. Power and Control
This rugged connector connects to a power supply and it contains control signals. A plug with screw-
terminals and retaining screws for power and control connector is supplied with each M!DGE3. It is
Tyco 7 pin terminal block plug, part No. 1776192-7, contact pitch 3.81 mm. The connector is designed
for electric wires with a cross section of 0.5 to 1.5 mm2. Strip the wire leads to 6 mm (1/4 inch). Isolated
cables should receive PKC 108 or less end sleeves before they are inserted in the clip. Insert the cables
in the wire ports, tightening securely.

2.2.4. ETH5 (SFP)
Fig. 2.8: SFP slot
ETH5 is a standard SFP slot for 10/100/1000 Mb/s
Ethernet SFP modules, user exchangeable with
maximal power consumption 1.25 W. Both fibre
optic and metallic Ethernet SFP modules are
supported. For optical both single and dual mode
fibre optics Ethernet modules (= 2 or 1 fibers) can
be used. CSFP modules are not supported. RA-
COM offers all mentioned types of SFP modules,
tested to be M!DGE3 compatible as a standard
accessory.
The SFP status LED is located just next to the
slot. It is controlled by SFP module. Its function
is specific for each SFP module. The typical beha-
vior is an indication the received signal from the
fibre optic or metallic link to be within operational
range.
Important
It is strongly recommended to use a high quality SFP module with industry temperature range.
The SFP modules listed in Accessories are thoroughly tested by RACOM and are guaranteed
to function with M!DGE3 units. It is possible to use any other SFP module, but RACOM cannot
guarantee they will be completely compatible with M!DGE3 units.

2.2.5. COM
M!DGE3 provides serial interface COM terminated by 5 pin terminal connector. It can be configured
as RS232 or RS485.
RS232 of M!DGE3 is a hard-wired DCE (Data Communication Equipment) device. Equipment connected
to the serial port of M!DGE3 unit should be DTE (Data Terminal Equipment).
