ER75i V2



GPRS/EDGE ER75i v2 router is used to wirelessly connect various equipment and devices via Ethernet interface 10/100 to the Internet or intranet. Thanks to the 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 the service of machines, or for data transfer from solar or wind power plants. Other benefits and advantages include high modularity – the router offers options to connect various user devices via Ethernet 10/100, RS232, RS485, RS422, MBUS or I/O. The FULL version of the router can be equipped by WiFi module (XC-WiFi), WMBUS module (XC-WMBUS) or SDH module (XC-SD) – Optional interfaces.

Key features

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 the 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, interface ports RS232 / RS485 / RS422 / MBUS / Switch or (I/O – CNT). Port2 may be equipped with interfaces RS232 / RS485 / RS422 / MBUS / WiFi / WMBUS / Switch / SDH or (I/O – CNT). Another option is the insertion of XC-SW board providing 3 x switched Ethernet 10/100 ports. 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 a password. The GPRS/EDGE router supports the creation of VPN tunnels using technologies IPsec, OpenVPN and L2TP to ensure safe communication. The web interface provides detail statistics about the wireless router activities, signal strength, detailed log, etc. The router supports the following 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 the case of connection losses, or a 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 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 automatically upgrade configuration and firmware from the server. This allows for a mass reconfiguration of many routers in one time. For easy use – additional software may be used – communication VPN server SmartCluster and software for router monitoring R-SeeNet.
