RS485-MODBUS water meter wiring method:
Red - power supply
Black - Ground
White (yellow) - RS485+
Blue (green) - RS485-
RS485 MODBUS water meter Features:
1. Meet the "electronic remote meter" (CJ / T224-2012) standards;
2. Usually no power, powers by the bus power supply only when meter reading / switching valve, data acquisition, data transmission or valve control according to the requirements of the command;
3. The meter has a unique address identifier, according to the address can read the corresponding data to ensure data uniqueness, correctness;
4. Control function, comes with the valve, according to the need to switch to prevent malicious arrears of water charge;
5. Combine with the host computer system, established remote automatic meter reading management system, really realized meter reading, monitoring automation.
