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.

External or internal power supply of module Expansion port RS485/RS422 can be
made by wiring jumpers J2 and J3 on this module. If external power supply of the module is
required, jumpers J2 and J3 must be connected to pins 2 - 3. Internal power supply is made
by connecting pins 1 - 2 with jumpers J2 and J3.

Interface behaviour of module Expansion port RS485/RS422 can be made by wiring
jumpers J4, J5 and J6 on this module. If RS485 is required, jumpers J4 and J5 must be
connected and jumper J6 disconnected. If RS422 is required, jumpers J4 and J5 must be
disconnected and jumper J6 connected.

Jumper placement can be seen in the picture below (module Expansion port
RS485/RS422 from TOP layer). We recommend that internal power supply is only chosen in
the event that it is not possible to ensure external power supply. If internal power supply is
chosen, converter RS485/RS422 is not galvanic separated.

For the majority of applications with a built-in modem in a switch board it is possible to
recognize two sorts of environments:

• non public and industry environment of low voltage with high interference,

• public environment of low voltage without high interference.

For both of these environments it is possible to mount modems to a switch board,
the following is no need to have examination immunity or issues in connection with EMC
according to EN 60439-1 ed.2.

For compliance of EN 60439-1 ed.2 specification it is necessary to observe next
assembly of the modem to the switch board:

• 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.

4.8. VRRP Configuration

To enter the VRRP configuration select the VRRP menu item. VRRP protocol (Virtual
Router Redundancy Protocol) is a technique, by which it is possible to forward routing from
main router to backup router in the case of the main router failure. If the Enable VRRP is
checked, then it is possible to set the following parameters. Parameter Virtual Server IP
Address sets virtual server IP address. This address should be the same for both routers. a
connected device sends its data via this virtual address. Parameter Virtual Server ID
distinguishes one virtual router on the network from others. This implies that the main and
backup routers must use the same value for this parameter. The router, with higher priority
set by the parameter Host Priority, is the main router. According to RFC 2338 the main router
has the highest possible priority - 255. The backup router has priority in range 1 – 254 (init
value is 100). The priority value equals 0 is not allowed.

It is possible to set Check PPP connection flag in the second part of the window.
The currently active router (either main or backup) will send testing messages to defined
Ping IP Address at periodic time intervals (Ping Interval) with setting time of waiting for
answer (Ping Timeout). The function check PPP connection is used as a supplement of
VRRP standard with the same final result. If there are no answers from remote devices (Ping
IP Address) for a defined number of probes (Ping Probes), then connection is switched to the
other line. It is possible to use for example a DNS server of mobile operator as a test
message (ping) IP address. There's an additional way for evaluating the state of the active
line. It is activated by selecting Enable traffic monitoring parameter. If this parameter is set
and any packet different from ping is sent to the monitored line, then any answer to this
packet is expected for Ping Timeout. If Ping Timeout expires with no answer received then
process of testing the active line continues the same way like in the case of standard testing
process after first test message answer drops out.

4.9. GPRS Configuration

To enter the GPRS connection configuration select the GPRS menu item.
If the Create GPRS connection option is selected, the modem automatically tries to establish
GPRS connection after switching-on. In this window it is possible to define Username,
Password and IP address for two different APN. If the IP address field is not filled in,
the operator automatically assigns the IP address when it is establishing the connection.

If the APN field is not filled in, then ER 75i automatically selects the APN by the IMSI
code of the SIM card. If the PLMN (operator number format) is not in the list of APN, then
default APN is “internet“. The mobile operator defines APN. The PLMN parameter is possible
to define in Operator item. By parameter PIN it is possible to put PIN to the SIM card always
during the starting of the ER 75i.

Attention! If one SIM card is inserted into the ER 75i, which has two different APN’s,
the ER 75i cannot have the second SIM socket mounted. Otherwise it will switch to
secondary APN false. Also, correct PIN must be filled. For SIM cards with two APN’s
there will be the same PIN for both APN`s. Otherwise the SIM card can be blocked by
false SIM PIN.

The choice Get DNS address from operator is given for easier configuration on client
side. If this field is filled in, then the ER 75i tries to get an IP address of primary and
secondary DNS server from the operator automatically.

If the Check PPP connection option is selected, it has active control of connection
over PPP. The modem will automatically send the ping question to the selected IP address
(Ping IP Address) in periodic time intervals (Ping Interval). After three unsuccessfully pings
on appropriate IP address the ER 75i terminates connection and tries to establish a new
connection. It is possible to use, for example, the DNS server of a mobile operator as the
ping IP address.

If the Enable Traffic Monitoring option is selected, then the router stops sending ping
questions to the Ping IP Address and it will watch traffic in PPP connection. If PPP
connection is without traffic longer than the Ping Interval, then the router sends ping
questions to the Ping IP Address.

Parameter Data limit set limit for sending via GPRS. By the parameter Accounting

Start it is possible to specify after which amount of data will start accounting defined in Data
limit. If the parameter Switch to backup SIM card when data limit is exceeded (see next) or
Send SMS when datalimit is exceeded (see SMS configuration) are not selected the data

limit will not count.

Parameter Warning Threshold determine per cent of Data Limit, which if is exceeded,
then the router sends an SMS in the form Router has exceeded (value of Warning
Threshold) of data limit.

At the bottom of configuration it is possible to set rules for switching between two
APN’s on the SIM card, in the event that one SIM card is inserted or between two SIM cards,
in the event that two SIM cards are inserted. Parameter Default SIM card sets default APN or
SIM card, from which it will try to establish the PPP connection. If this parameter is set to
none, the router launches in off-line mode and it is necessary to establish PPP connection
via SMS message. If PPP connection fails, then the parameter Switch to other SIM card
when connection fails ensures switch to secondary SIM card or secondary APN of the SIM
card. In case that the roaming is detected the parameter Switch to backup SIM card when
roaming is detected enables switching to secondary SIM card or secondary APN of the SIM
card. Parameter Switch to backup SIM card when data limit is exceeded enables switching to
secondary SIM card or secondary APN of the SIM card, when the data limit of default APN is
exceeded. Parameter Switch to primary SIM card after timeout defines conditions, how to
switch back to the default SIM card or default APN. Parameter Switch to primary SIM card
after timeout enable defines the method, how the router will try to switch back to default SIM
card or default APN.

If parameter Backup SIM card is set to none, then parameters Switch to other SIM

card when connection fails, Switch to backup SIM card when roaming is detected and Switch
to backup SIM card when data limit is exceeded switch the router to off-line mode.

Parameter Initial Timeout sets the time after which the ER 75i tries to make connection
with default APN, range of this parameter is from 1 to 10000 minutes. Parameter Subsequent
Timeout sets the time period for every other next attempt to make connection with default
APN, range is from 1 to 10000 minutes. Parameter Additive Constant sets the amount of time
which is added to every attempt at main connection establishment after unsuccessful defined
attempt (for example: after a second unsuccessful attempt at main connection establishment
time of next attempt is extended by about 30 minutes etc.). Range is from 1 to 1000 minutes.

Attention! We recommend checking the GPRS connection in case of uninterrupted
running

13. Guarantee Claim Guidelines

Dear customer,

The product that you have purchased was tested by the manufacturer and, before
it was sold, the product’s functions were checked once more by our company’s technician.
However if, in spite of the above-mentioned measures, a breakdown of this product occurs
during the guarantee period, which makes proper utilization of the product impossible,
we ask you to observe the Guarantee Claim Guidelines when asserting a guarantee claim.

To facilitate the possible guarantee claim procedure, please, when taking over
the product, make sure that the seller, who is selling you the product, has properly filled
in the relevant parts of the guarantee certificate, including the date of sale, stamp
and signature.

This guarantee claim procedure applies to the products that have been purchased.
This guarantee claim procedure does not apply to the services that have been provided.

Guarantee periods of products

Guarantee of the purchased device, power supply unit, antenna, data cable,
and possible accessories is provided, with a guarantee period of 24 months from the date
of sale. The date of sale is at the same time the date of acceptance of the product
by the customer.

Lodging a guarantee claim

The guarantee claim must be lodged at the seller from whom the relevant object
of the guarantee claim has been purchased. When lodging the guarantee claim,
the customer is to submit the properly filled-in guarantee certificate and the complete object
of the guarantee claim. The object of the guarantee claim should be submitted in a state
corresponding to the state at the sale.

Caution!

The seller does not guarantee that individual settings or data stored in the object
of the guarantee claim will be retained.

When lodging the guarantee claim, the customer is obligated to specify the particular
defect of the guarantee claim object, possibly its symptoms and, furthermore, the particular
right resulting from the liability for defects that he is asserting.

Settling a guarantee claim

Depending on the circumstances, the seller shall ensure the defect removal free
of charge; possibly, the seller shall exchange the object of the guarantee claim for a new
product or, possibly, settle the guarantee claim in a different way which is in compliance
with the Civil Code and with the Consumer Protection Act.

At the moment when the customer has lodged the guarantee claim and the object
of the guarantee claim has been accepted by the seller, running of the guarantee period
is interrupted. Running of the guarantee period shall continue from the date of acceptance
of the repaired object of the guarantee claim or of the exchanged faultless product
by the customer or, in the event that neither of the two has been accepted by the customer,
from the date when the customer was obligated to accept the repaired object
of the guarantee claim or the exchanged product. In the event that a guarantee claim
resulting from a defect covered by the guarantee has been lodged and the defective object
of the guarantee claim has been exchanged by the seller for a new product (including the
exchange of the IMEI), the ownership of the original object of the guarantee claim is passed

hereupon onto the seller, and the ownership of the new product, onto the buyer. A new
guarantee period starts running from the date of acceptance of the new product. In the event
that the seller, upon agreement with the customer, has settled the guarantee claim by
exchanging the object of the guarantee claim for a faultless product, the new guarantee of
the product shall expire as follows:

1. After the expiration of a period of 12 months from the date of acceptance
of the exchanged product by the customer.

2. On the date when the guarantee period of the original product (the object
of the guarantee claim) would have expired if the original product had not been
exchanged, whichever is later.

3. The guarantee claim is not justified if the defect being claimed has not been
detected by the seller within the framework of the guarantee claim settlement,
or if the guarantee does not apply to the defect of the product pursuant to Article
4 of the Guarantee Claim Guidelines.

4. If the defect being claimed has not been detected, and the functional state
of the guarantee claim object has been demonstrated to the customer,
the customer is obligated to refund the provable expenses incurred in connection
with expert assessment of the defect being claimed.

5. If, during the process of assessment of justifiability of the guarantee claim,
a defect of the product is detected which is not covered by the guarantee (a repair
not covered by the guarantee), the seller shall notify of this fact the customer,
and the customer shall notify the seller whether he wants to have this defect
removed at a price quoted by the seller. Precise conditions of the repair not
covered by the guarantee will be specified in a drawn-up report signed
by the customer and seller. If the customer does not require the defect removal
by a repair not covered by the guarantee under the conditions communicated
by the seller, the device will be returned to the customer, after he has refunded
the provable expenses incurred in connection with the expert assessment
of the claimed defect.

The guarantee does not apply to the defects caused by the following:

1. Mechanical damage (e.g. by a fall, etc.).

2. Utilization of power supply units and other accessories that are not suitable,
possibly, are not recommended for the particular product.

3. Interconnecting the product with non-standard accessories.

Other guarantee claim conditions

The fact that the object of the guarantee claim does not correspond to parameters
that have been set for other similar types of products can not be considered to be a defect.

The guarantee shall be terminated in the event of any modification of the object
of the guarantee claim or in the event that the serial number of the object of the guarantee
claim has been damaged or is illegible due to other reasons.
