SAFETY INSTRUCTION

1. Safety instruction

Please, observe the following instructions:

• The communication module must be used in compliance with 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.
Unauthorised modifications or utilization of accessories that have not been approved may
result in damage to the communication module and in a breach of applicable regulations.
Unauthorized modifications or utilization of accessories that have not been approved may
result in the termination of the validity of the guarantee.

• The communication module must not be opened.

• 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.

• When using the communication module in the 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, the telephone
may cause interference.

• It is recommended that you should create an appropriate copy or backup
of all the important settings that are stored in the memory of the device.

2. Description of the router

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 Host interface which is designed only
for connection to a USB device.

By customer request it is possible to equip the router with the PORT1 module, PORT2
module and extend the function of the EDGE router about RS232, RS485/RS422,
ETHERNET, M-BUSD or CNT (I/O module).

The EDGE router has two versions. The first version is basic ER75i v2 and the second
version is ER75i v2 SL in the aluminum box.

Examples of Possible Applications

• mobile office

• fleet management

• security system

• telematic

• telemetric

• remote monitoring

• vending and dispatcher machines

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 router. To initiate the router into operation it is necessary to insert an activated SIM card
with unblocked PIN in the reader. The SIM cards might be of different adjusted APN (Access
Point Name).

2.5. Power Supply

The router requires +10 V DC to +30 V DC supply. Protection against reversed polarity
without signaling is built into the router.

2.12. Putting into operation

Before putting the ER75i v2 or ER75i v2 SL router into operation it is necessary
to connect all components needed for the operation of your applications and the SIM card
must be inserted (the modem is off).

The modem is put into operation by connection of the power supply to the modem.
In the default setting the modem starts to login automatically to the preset APN. The behavior
of the modem can be modified by means of the web interface which is described
in the following chapter.

to recognize two sorts of environments:

For the majority of applications with a built-in modem in a switch board it is possible

• no public and industry environment of low voltage with high interference,

• public environment of low voltage without high interference.

the following there is no need to have examination immunity or issues in connection with
EMC according to EN 60439-1 ed.2:00 + A1:04.

For both of these environments it is possible to mount modems to a switch board,

to observe next assembly of the modem to the switch - board:

For compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary

• for round antennas we recommend to observe a distance of 6 cm from cables

and metal surfaces on every side according to the next picture due to the elimination

of interference, while using an external antenna except for the switch-board it is

necessary to fit a lightening conductor,

• before mounting a modem on sheet-steel we recommend using an external antenna,

• for single cables we recommend to bind the bunch according to the following picture,

for this use we recommend:

 length of the bunch (combination of power supply and data cables) can

be maximum 1,5 m, if the length of data cables exceeds 1,5 m
or in the event of, the cable leads towards the switch - board, we
recommend installing over - voltage protectors (surge suppressors),

 with data cables they mustn't carry cables with reticular tension

~ 230 V/50 Hz,

 all signals to sensors must be twisted pairs.

• sufficient space must be left before individual connectors for handling of cables,

• for correct function of the modem we recommend to use in the switch-board earth-

bonding distribution frame for grounding of power supply of modem, data cables

and antenna,

3.1. Expansion port mounting for ER75i v2

Attention! Expansion port PORT1 and PORT2 include when the router ER75i v2 SL

is switched off.

After removing front head of the box it is possible to take out the B-RB-v2
motherboard (position 1). The expansion port PORT1 (position 2) is connected to connector
J8 (see below) of the router B-RB-v2 motherboard (position 1) from TOP side. The
expansion port PORT2 (position 3) is connected to connector J3 (see below) of the router B­RB-v2 motherboard (position 1) from TOP side. The expansion port is mounted to the
motherboard by the help of three spacers (position 10). After mounting the expansion port
the box is inserted motherboard into box and kneaded front head in the box.
