CMc LTE Box

CMc LTE Box

The CMc LTE Box is a solution for remote meter reading via a mobile network. The CMe2100 LTE M-Bus Metering Gateway combined with an M-Bus Master from the CMeX10-13S Series makes it possible to read up to 256 M-Bus meters.

Communication takes place with support for the mobile LTE (4G) network and an automatic fallback function. The CMc LTE Box is fully pre-assembled and wired in a protective enclosure on delivery, thereby requiring minimal installation effort.

Elvaco's CMc LTE Box consists of our M-Bus Metering Gateway CMe2100 LTE, an external magnet mount antenna, and an M-Bus Master from the CMeX10-13S Series (only for 32-256 meters), fully assembled and connected in a protective enclosure at delivery. This box-build solution is used to read up to 256 M-Bus meters, compile meter data in customized reports and deliver it to a receiving system. This by a set time schedule and integration protocol via a mobile network with support for LTE communication and automatic fallback function (2G/3G/LTE). Our Wireless M-Bus Receiver CMeX50, which enables communication with up to 256 Wireless M-Bus meters is available as an add-on option.
