Product overview

Application description

The CMeX50 is a wireless M-Bus Receiver handling up to 800 wireless M-Bus slaves and up to 32 wired MBus slaves. The product can operate in all commonly used wireless M-Bus modes; T1, C1, and S1.

The CMeX50 will virtualize the connected wireless M-Bus slaves and the slaves will be readable using standard M-Bus commands. The CMeX50 can be read using RS232, USB and standard M-Bus 2-wire. This makes the product usable in any standard M-Bus system, without having any knowledge about wireless M-Bus.

The CMeX50 can be used together with Elvaco CMe/CMeX Series products, which enables GSM/GPRS communication, TCP/IP communication, M-Bus Master extension modules and much more.

The CMeX50 should be used in the following scenarios:

  • Radio networks in villa-areas

  • Radio networks in tenant owners associations

  • Reading any type of wired M-Bus slave

  • Reading any type of wireless M-Bus slave supporting T1, C1, or S1
