Wiring
Communication
The RS-485 communication mode allows up to 32 DCM series energy meters to be connected to one bus, and is connected to the host computer through an RS-485 converter.Communication cable can adopt ordinary screened twisted pair, and the total length shall be no more than 1200 meters,all RS-485 ports of positive and negative polarity must be connected correctly.If shielded twisted-pair cable is longer, Suggestions on its end by one of about 120 Ω resistance in order to improve the reliability of communication.
