M!DGE cellular routers have been specially designed for SCADA and Telemetry, nevertheless are well suited to many different wireless applications. M!DGE HW and SW is ready to maintain reliable and secure connections from an unlimited number of remote locations to a central server. Both standard Ethernet/IP and serial interfaces are available. Moreover, two digital inputs and two digital outputs can be used for direct monitoring and control of application devices.

M!DGE versatility is further enhanced by the two independent Ethernet ports. These can be configured to either support two independent LANs (e.g. LAN and WAN settings), or simply connect two devices within one LAN (effectively replacing an Eth switch). M!DGE software is based on well proved components, including an Embedded Linux operating system and standard TCP/IP communication protocols.

M!DGE combined with an MG102i two-SIM router in one network is quite easy to do because of fully compatible interface settings and behaviour on all HW interfaces. Thanks to compact size and versatility, M!DGE cellular routers prove indispensable in many SCADA and Telemetry, as well as POS, ATM, Lottery and Security/Surveillance applications.

M!DGE, together with the RACOM RipEX radio router, offers an unrivalled solution for combining Cellular and UHF/VHF licensed radio in a single hybrid network. Even a single RipEX in the centre of a M!DGE network allows for efficient use of addressed serial SCADA protocols.
