Abstract

Dispositif de multiplexage de messages codés en binaire et arrivant sur plusieurs lignes d'entrée échantillonnées cycliquement, les résultats de l'échantillonnage étant transformés en formats de caractères et transférés sur une voie multiplex, les formats de caractères comprenant chaque fois un caractère et une adresse. Le dispositif comprend deux étages de traitement; le premier dans le sens de la réception forme mot de comptage donnant le nombre de données échantillonnées reçues successivement sans changement de polarité; le second étage convertit les mots de comptage en formats de caractère à transmettre en utilisant les données stockées pour chaque ligne individuellement et transfère ces formats de caracteres sur la voie multiplex de sortie 15. Applications courantes.Device for multiplexing messages encoded in binary and arriving on several cyclically sampled input lines, the results of the sampling being transformed into character formats and transferred on a multiplex channel, the character formats comprising each time a character and an address . The device comprises two processing stages; the first in the direction of reception forms a count word giving the number of sampled data received successively without change of polarity; the second stage converts the count words into character formats to be transmitted using the data stored for each line individually and transfers these character formats to the output multiplex channel 15. Common applications.
