3. Description of the router
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 capa-
bilities 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 main-
tenance 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, Win-
dows XP, Windows Vista or Windows Seven operating system. EDGE router is only available
in one basic version called ER75s. Allows user to use one SIM card to connect to the GSM
network and is embedded in a plastic box.
Configuration is done via web interface protected by password. The GPRS/EDGE router
supports creation of VPN tunnels using technologies IPsec, OpenVPN and L2TP to ensure
safe communication. Web interface provides detail statistics about the wireless router activi-
ties, signal strength, detailed log, etc. Router supports functions: DHCP, NAT, NAT-T, DynDNS,
NTP, VRRP, control by SMS and many other functions.
Other diagnostic functions ensuring continuous communication include automatic inspec-
tion of PPP connection offering an automatic restart feature – in case of connection losses,
or hardware watchdog which monitors the status of the router. With the help of a special win-
dow (start up script window) you may insert Linux scripts for various actions. For some appli-
cations the key option to create several different configurations for one wireless GPRS/EDGE
router, the so-called profiles (maximum of 4), and the option to switch between them (for exam-
ple via SMS, binary input status, etc.) is essential. Cellular wireless routers may automatically
upgrade configuration and firmware from server. This allows mass reconfiguration of many
routers in one time.
Examples of possible applications:
•mobile office
•image transmission
•security systems
•telematics
•telemetry
•remote monitoring
•monitoring of traffic information
•vending and dispatcher machines

5.4 Mechanical dimensions and mounting recommendations
Router is standardly designed for:
•mounting to a panel using through holes,
•possibility to be put on a work surface,
•mounting onto the DIN rail by the plastic clips, which are included.
For the most of applications with a built-in router in a switch board it is possible to recognize
two kinds of environments:
•no 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 router to a switch board, 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 + Opr.1:08 + Z1:10.

ER75s
For compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary to observe
next assembly of the router to the switch – board:
•for whip 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 interfer-
ence, while using an external antenna except for the switch-board it is necessary to fit a
lightening conductor,
•before mounting a router on sheet-steel we recommend using an external antenna,
Figure 4: Space around antennas
•For every cables we recommend to bind the bunch according to the following picture,
we recommend for this use:
–Length of the bunch (combination of power supply and data cables) can be max-
imum 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,
Figure 6: Space in front of connectors
•For correct function of the router we recommend to use in the switch-board earth-
bonding distribution frame for grounding of power supply of router, data cables and
antenna.
