СПОСОБ ПЕРЕДАЧИ ДИСКРЕТНЫХ ЭЛЕКТРИЧЕСКИХ СИГНАЛОВ

摘要

FIELD: data transmission; communication interfaces for electronic devices. ^ SUBSTANCE: transmitter and receiver are disposed on two-wire communication line whose lead is connected to voltage supply through limiting resistor. Proposed method includes transmission of binary-coded logical signal by closing line with aid of transmitter using electronic switch for the purpose and reading out line voltage by means of receiver; prior to signal reading, limiting resistor value is increased by minimum 1.5 times and upon reading original resistance is recovered. ^ EFFECT: facilitated procedure. ^ 1 cl
