RS485 is a baud commnication port within Calin's meter. It provides the most comprehensive raw data of the meter including metrological value, firmware version, tariff plans, interval settings, alarm threshold, etc. Multi-storey buildings, multi-dweller complexing, student dormitry, body corporates, section-tile community of densely populated areas are perfect situation for this setup. Meters are normally locked away from cutomers premises in a cabinet or kiosk, allowing wired connection in most limited space. For communication with the back end server, a data collector or mini-concentrators can be utilized to link with the meter cabinet as a group control unit, and through GPRS or cable connected to the head-end server.

 

The communcation between the meter and the server is two-way, meaning meter transmit data and receive command from the head-end as well. A utility can implement load management control with the data readout and analytic tools of the system.
