EMR-2 & EMR-4 models are industrial WAN routers designed for data transport services at secondary substations. Both of them intended for harsh industrial conditions, exceeding the stringent levels of isolation, immunity and protection

GSM/GPRS (2G), UMTS/HSDPA (3G) and LTE (4G) transmission technologies.
Dual SIM operation to provide access to more than one operator.
Fast Ethernet ports with Automatic speed detection.
VLANs management per port.
Local and remote management through a console or a built-in web server (http/https), SSH and Telnet server.
SNMPv1, SNMPv2c and SNMPv3.
DHCP, NTP, TACACS+ and RADIUS.
Static and dynamic routing capabilities (RIP, OSPF).
VRRP redundancy protocol.
NAT rules, filtering and Stateful IP firewall.
QoS assignment and management.
IPSec tunnels with DMVPN support, NHRP.
Version with RS-232/RS-485 interface to perform serial to IP encapsulation functions.
Encapsulation protocols: IEC 60870-5-101/102/103, DLMS, GESTEL, MODBUS, DNP 3.0, SAP20, PROCOME, Pid1 and Twc.
