3. Router description
GPRS/EDGE ER75i v2 router is used to wirelessly connect various equipments and devices
via Ethernet interface 10/100 to the Internet or intranet. Thanks to high security level and wide
coverage of GPRS/EDGE technology provided by mobile phone operators, it is mostly used
in industrial applications, for remote maintenance and service of machines, or for data transfer
from solar or wind power plants. Other benefits and advantages includes high modularity –
the router offers option to connect various user devices via Ethernet 10/100, RS232, RS485,
RS422, MBUSor I/O.
As a standard, this industrial ER75i v2 wireless router is equipped with one Ethernet 10/100,
one USB Host port, one binary input/output (I/O) port and one SIM card. To save and backup
communication data a version with 2 SIM cards is available. The wide range of interface
options of this wireless router further expands an optional Port1 and Port2 - selected
by
the
customer – for example Ethernet port 10/100, serial interface ports
RS232/RS485/RS422/MBUS or (I/O - CNT). Port2 may be equipped with serial interfaces
RS232/RS485/RS422/MBUS or (I/O - CNT). The wireless router is supplied either in a plastic
or metal casing, based on the requirements of the customer.
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
activities, 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 inspection
of PPP connection offering an automatic restart feature - in case of connection losses,
or hardwarewatchdog which monitors the status of the router. With the help of a special
window (start up script window) you may insert Linuxscripts for various actions. For some
applications 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 example via SMS, binary input status, etc.) is essential. Cellular wireless routers may
automaticallyupgradeconfiguration and firmware from server. This allows mass
reconfiguration of many routers in one time.
For easy use additional software may be used - communication VPNserver Digicluster
and software for routermonitoring R-SeeNet.
