Kara SystemsThe Kara BACnet gateway is a 2 in 1 gateway for BACnet. It integrates M-Bus meters and Modbus devices into BACnet infrastucture. It represents a BACnet Device and several BACnet objects. M-Bus meters are converted to BACnet Analog Inputs. Modbus Input discrete and Coils are converted to BACnet Binary inputs and outputs respectively and Modbus Input/Holding Registers and converted to BACnet Analog input and output objects.
The connection to BACnet is done over Ethernet LAN BACnet/IP or BACnet/Ethernet. To connect the gateway to M-Bus you need a Level Convertor to convert the EIA-232( optional EIA-485) connection to M-Bus physical Bus.
