RS485 Hotel Switch Lighting Control Switch

Typical serial communication standards are RS232 and RS485, which define voltage, impedance, etc., but do not define software protocols. The RS-485 bus standard specifies the electrical characteristics standard of the bus interface, that is, the definition of two logic states: the positive level is between +2V~+6V, indicating a logic state; the negative level is between -2V~-6V, It represents another logic state; the digital signal adopts the differential transmission method, which can effectively reduce the interference of the noise signal.
