Racom MIDGE 3 - Industrial LPWA IoT Router

Global LTE Cat-M1+ NB-IoT

4xGbE, 1xSFP, 1xRS232/485, 3xDI/O, IEC 61850-3

Version: MIDGE3-N-O (Global LTE Cat M1/NB-IoT)

MIDGE 3 from Racom is an industrial grade cellular router designed for demanding and mission-critical SCADA and telemetry applications - targeting sectors such as power and water utilities, oil & gas distribution and similar. It has been designed based on all relevant state-of-the art concepts to offer reliable 24/7/365 service, meeting both current and future market needs.

As such it offers a wide range of features for connectivity, protocol support, routing, troubleshooting, cyber security and management in combination with a highly robust hardware design certified for use in electrical substations (IEC 61850-3). 

For users of Racom RipEX 2 radios, the MIDGE 3 also offers a fully compatible feature set to allow for hybrid networks, as it is based on the same software platform. It has never been easier to build hybrid Cellular & VHF/UHF based private networks.

Model Specific

M!DGE3-N-O utilizes the Cinterion TX62-W-B chipset featuring global LTE Cat M1 & LTE NB1 / NB2 band support.

In this configuration utilising the mPCIe expansion slot is not possible, meaning you cannot add extra serial ports using "Option C".
