摘要

Asynchronous communications system between central series computer and peripherals unlimited number of intelligent. The system is intended to establish communication between an intelligent central unit, known as master, and a plurality of and independent units intelligent, called slave. The form uses three conductores physicists, incorporating both the master unit as slave units a microprocessor and associated circuitry design of the communication signals relative. The microprocessor of the master unit has one input and one united out a return lines and communication, respectively, through respective conditioning circuits communication signals, while the microprocessor / es of slave units have / n two inputs and one output. Both units, master and slave, can act transmitter and receiver, allowing bidirectional communication. (Machine-translation by Google Translate, not legally binding)
