result in the termination of the validity of the guarantee.
•The communication module must not be opened. Only the replacement of the SIM card is
permitted.
•Caution! The SIM card could be swallowed by small children.
•Voltage at the feed connector of the communication module must not be exceeded.
•Do not expose the communication module to extreme ambient conditions. Protect the
communication module against dust, moisture and high temperature.
•It is recommended that the communication module should not be used at petrol stations.
We remind the users of the duty to observe the restrictions concerning the utilization
of radio devices at petrol stations, in chemical plants, or in the course of blasting works
in which explosives are used.
•Switch off the communication module when travelling by plane. Utilization of the
communication module in a plane may endanger the operation of the plane or interfere with
the mobile telephone network, and may be unlawful. Failure to observe these instructions
may result in the suspension or cancellation of telephone services for the respective client,
or, it may result in legal sanctions; it may also result in both eventualities.

2. Description of the ER 75i, ER 75i DUO and ER 75i SL
routers
2.1. Introduction
EDGE router is a compact electronic device based on the module which enables data
transfers using GSM, GPRS and EDGE technologies.
Primarily, the router expands the capabilities of the module by the option of connecting
more PCs by means of the built-in Ethernet interface. In addition, the firmware of the router
provides automatic establishment and maintenance of GPRS connection. By means
of integration of a DHCP server it provides the users with simple installation and Internet
access.
In addition, the router is equipped with a USB 2.0 Full Speed interface which is designed
only for connection to a PC with Windows 2000, Windows XP or Windows Vista operating
system. For operation it is sufficient to install drivers from the supplied CD to the PC.
By consumer request it is possible to equip the router with a modulus port PORT1
and extend the functionality of EDGE router about RS232, RS485/RS422, M-BUS or CNT (I/O
module).
The EDGE router has three versions. The first version is the basic ER 75i, the second
version is the ER 75i DUO with two SIM cards and last version is the ER 75i SL in an
aluminum box.
Examples of Possible Applications
•mobile office
•image transmission
•security system
•telematics
•telemetry
•remote monitoring
•monitoring of traffic information
•vending and dispatcher machines

Router ER 75i is standardly designed for:
•mounting to a panel using through holes (only version ER 75i and ER 75i DUO),
•or possibility to be put on a worktop,
•mounting onto the DIN rail by the plastic clips, which are included.
2.3. Antenna Connection
The whip antenna is connected to the router using an FME on the back panel.
External whip antenna:
2.4. SIM Card Reader
The SIM card reader for 3 V and 1.8 V SIM cards is located on the front panel
of the modem. For putting the modem into operation it is necessary to insert an activated SIM
card with unblocked PIN in the reader.
1. Make sure that the modem is not being powered.
2. Press the small yellow button next to the reader to eject the reader holder.
3. Insert the SIM card in the reader holder and slide it in the reader.
2.5. Power Supply
The router requires +10 V DC to +30 V DC supply. Protection against reversal
of polarity without signaling is built into the modem.
The power consumption during receiving is 1W. The peak power consumption during
data sending is 5,5 W. For correct operation it is necessary that the power source is able to
supply a peak current of 500 mA.

2.7. Description of individual components of the router
2.7.1. GSM/GPRS/EDGE module
The MC75i OEM module is used for GSM network wireless communication. It is
integrated into the printed circuit board. The slide-out SIM card reader is accessible from
the front panel. The FME antenna connector is accessible from the back panel.
The router is equipped with a USB 2.0 Full Speed interface which is brought to the
USB-B connector marked USB. The MC75i module is connected to the control computer via
the RS-232 high-speed serial interface.
GSM/GPRS/EDGE module
•Communicates in four GSM bands (850MHz, 900MHz, 1800MHz, and 1900MHz).
•In the GPRS mode it is able to transmit in three „Time Slot“ and receive in two (GPRS
multi-slot class 10 – the maximum bit rate of reception is 42.8 kb/s) or transmit in one
„Time Slot“ and receive in four (GPRS multi-slot class 12 – the maximum bit rate
of reception is 85.6 kb/s).
•In the EDGE mode it is able to transmit in three „Time Slot“ and receive in two (EDGE
multi-slot class 10 – the maximum bit rate of reception is 118.4 kb/s) or transmit in one
„Time Slot“ and receive in four (GPRS multi-slot class 12 – the maximum bit rate
of reception is 236.8 kb/s).
•Supports coding schemes CS1 to CS4 and MCS1 to MCS9.
Beware! The transmitting and receiving in timeslots depends on the operator networks
possibilities.
2.7.2. Control microcomputer
The core of the router is a 32-bit microprocessor with 16 MB RAM, 4 MB FLASH
EEPROM, serial interface RS232 and an Ethernet interface 10/100 Mbit/s. The microcomputer
is connected to the MC75i OEM module through the serial interface and controls
the communication via GSM/GPRS. Towards to the user it is connected on the Ethernet
interface.
The software is built on the uClinux operating system.
The router supports services such as DHCP, NAT, GRE, IPSec tunnels, etc.
The router settings are saved in the FLASH EEPROM memory. All configuration
of the modem can be done through a web interface (HTTP) which is security password
controlled.
