3. Router Description
EDGE industrial router ER75i v2 is used to wirelessly connect various equipments and de-
vices 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 mod-
ularity – the router offers option to connect various user devices via Ethernet 10/100, RS232,
RS485, RS422, MBUS or I/O.
As a standard, this industrial 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 communica-
tion data a version with two SIM cards is available. The wide range of interface options of the
router further expands expansion Port1 and Port2, which are selected by the customer. For
Port1 are available: Ethernet port 10/100, serial interface ports RS232, RS485, RS422, MBUS
or inputs/outputs (I/O – CNT). Port2 may be equipped with serial interfaces RS232, RS485,
RS422, MBUS, wireless interfaces WIFI or WMBUS, SDH expansion port or inputs/outputs
(I/O – CNT). Both of ports can be fitted with internal switch (exp. port SWITCH). This wire-
less 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. EDGE industrial 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
window (start up script window) you may insert Linux scripts for various actions. For some
applications the key option to create several different configurations for one 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 routers may automatically upgrade con-
figuration and firmware from server. This allows mass reconfiguration of many routers in one
time.
The router also supports additional software like R-SeeNet for permanent traffic monitoring
of routers or communication VPN server Digicluster.
