Abstract

L'invention concerne un système de couplage d'unités de traitement de données numériques réalisant un circuit de communication en duplex entre une unité << Pilote >> et une unité << Asservie >>, permettant un échange simultané de l'information dans les deux sens, et plus particulièrement un système de couplages qui comprend: deux blocs Emetteur/Récepteur identiques raccordés à une ligne de transmission en duplex (4 fils), chaque bloc Emetteur-Récepteur étant muni de moyen de connexion à un terminal et de moyens d'adaptation des niveaux logiques entre les terminaux et la ligne suivant un mode différentiel. L'invention s'applique au télétraitement (décentralisation des postes de saisies de données).
