Abstract
La presente invención se refiere a sistema para transmitir una corriente de datos, que comprende no mas de tres estados entre un par de estaciones vinculadas en forma conjunta por la línea de transmisión de datos, comprendiendo un tren de tres cables; caracterizado porque la estación transmisora de datos comprende medios para proveer la corriente de datos, un par de interruptores normalmente abiertos, cada uno conectado entre uno de los tres cables y un cable respectivo de los dos cables restantes, medios para leer secuencialmente cada estado de la corriente de datos y medios de control para cerrar uno de los dos interruptores para cada primer estado de datos leído de la corriente de datos, el otro de los dos interruptores para cada segundo estado de datos leído de la corriente de datos y para abrir ambos interruptores para cada tercer estado leído de la corriente de datos, y porque la estación receptora de datos comprende medios para proveer dos señales contínuas y diferentes, cada una de las cuales es salida a un cable respectivo de los dos cables restantes, medios para identificar cual de las dos señales es reflejada en un cable para determinar cual interruptor está cerrado, y medios para generar la corriente de datos en la estación receptora de datos a partir de la secuencia en la cual se abren y cierran los dos interruptores.
