AMCV M4-x8x(G), Mesh/RS485 converter

Converters Mesh/RS485 of AMCV M4-x8x(G) type are designed for collection of data from electricity meters in the distribution network equipped with RS485 interface and for their subsequent sending to the Mesh network.

Properties

  • Possibility to deliver the converter in LP (max. 10 mW) or HP (max. 500 mW) version regarding required range;
  • Converter can be parameterized as follows:
    router  - connected to a gateway of typu AMCV M4-C8HG (pict. 1) or AMCV MU-C8HG (pict. 2);
    gateway – allows data collection via AMCV M4-C8H  router, connection to a PC via USB/RS485 converter, e. g. AMCV U4;
  • Possibility to supply other network components from the external supply output + 5 V;
  • In order to improve the impact, it is possible to replace the standardly delivered antenna by an antenna with a cable equipped with SMA-male connector.
