TECHNICAL PRESENTATION
M!DGE cellular routers, specially designed for SCADA & Telemetry mission critical applications, are well suited to many different wireless applications like POS, ATM, Lottery and Security/Surveillance applications.
M!DGE is Linux OS based and has been designed with attention to detail, performance, quality and reliability. All relevant state-of-the-art concepts have been carefully implemented.
M!DGE is well proven within the market since 2012 in thousands of industrial installations in tens of countries worldwide providing 24/7 reliable service.
M!DGE2, the 2nd generation of M!DGE with 2 SIM cards and 4 Ethernet ports, introduced in 2018, is the top equipment for SCADA communication if a cellular network is required.
M!DGE together with RACOM RipEX radio modems offers an unrivalled solution for combining Cellular and UHF/VHF licensed radio in a single hybrid network. Both provide the same customized serial SCADA protocols on COM interfaces.
Take the opportunity to remotely access and test a live M!DGE unit here (admin, RacomDemo1234)
- Switch / Router
– M!DGE Ethernet ports can be configured either as Switch (one IP address) or Router (up to four physically separated ports with individual IP addresses). Any combination of switched/routered port is possible - Terminal server
– 2 independent sessions
– encapsulates serial protocol to TCP (UDP) and vice versa – suitable for IP and serial RTU’s combination within one network - Subnets
– IP aliases – one additional IP address (alias) for each LAN and LAN/VPN combination possible - VLAN
– 802.1Q – up to five VLANs can be assigned
– M!DGE management can be done over VLAN - NAPT
– masquerading, source and destination (IP/Mask/Port) translation supported - Virtual tunnels
GRE – end-to-end tunneling protocol
PPTP – basic encryption and authentication features, end-to-end
IPsec – cryptographic end-to-end
OpenVPN – cryptographic single server to multiple clients - QoS
– prioritize critical traffic (e.g. SCADA) over lower priority applications (e.g. management)
– 802.1p and DiffServ (DSCP) supported - Static and dynamic routing
– Static routing
– Extended routing – policy based routing
– Multipath routes – weighted IP session distribution for particular subnets across multiple interfaces
– OSPF (Open Shortest Path First) protocol – allowing to be added to a network of OSPF routers
– BGP (Border Gateway protocol) – peering with other BGP enabled routers
Serial
- Modbus, IEC101, DNP3, Comli, DF1, Profibus, Async Link, C24, Cactus, RP570, Siemens 3964(R) and others
- Serial SCADA protocol addresses are mapped to M!DGE IP addresses
Ethernet
- TCP (UDP) protocols (e.g. IEC104, DNP3/TCP) can be handled transparently or using Terminal server
- Embedded Modbus RTU / Modbus TCP converter
Device
- Digitally signed FW
Management
