AMCV M4x Mesh/RS485 converters are designed for collecting data from electricity meters in the distribution network equipped with an RS485 interface and sending them to the Mesh network. They can be configured as a router (connecting to an AMCV M4-CG or AMCV MU-CG gateway) or as a gateway collecting data through routers. Wireless ISM–Mesh communication in the 868–870 MHz band with a typical line-of-sight range of 2,000 m.
