IV. Operation Instructions
4.1 Panel diagram
The device has a two-wire RS-485 communication port with terminals labeled A+, B-. High-speed optocoupler isolation and protection circuits prevent common-mode and
differential-mode voltage interference, lightning strikes, and miswiring from damaging the communications port.
The RS-485 communication mode allows a maximum of 32 instruments to be connected on one bus. In this case, an RS-232C/RS-485 converter is required. The
communication cable can be an ordinary shielded twisted pair cable. The total length cannot exceed 1200 meters. The positive and negative polarity of the RS-485 port of
each device must be connected correctly, and one end of the cable shield is grounded. If the shielded twisted pair is long, it is suggested to connect a 120Ω resistor at the end
to improve the reliability of communication.

Display Description
Communication indicator: The indicator will keep blinking while it is passing
Switch input indicator, when a certain amount of switch is closed, the corresponding switch display frame will be filled with solid. If the second
way switch is turned on, the display state is as follows
：
Alarm or remote output indicator: When an alarm occurs, the corresponding output indicator will be filled with solid. Such as:
：
Display the current display category of the data display area: like the voltage corresponds to "U", the current corresponds to "A", etc.
Measurement data real-time display area, can display the voltage, current, power etc
