Abstract

L'appareil comprend une multiplicité de stations d'entrée ou d'introduction de données (1) et une station maitre (4) connectées mutuellement en une boucle (3) de manière à permettre à la station maitre (4) d'envoyer des données à un ordinateur personnel (5) et d'en recevoir des données. Les stations d'entrée (1) et la station maitre (4) sont interfacées à l'aide d'un controleur de liaison de données à haut niveau et la station maitre (4) est interfacée avec l'ordinateur personnel (5) à l'aide d'une liaison d'interface série constituée par adaptateur d'interface de communications asynchrone.The apparatus comprises a multiplicity of data input or input stations (1) and a master station (4) connected to each other in a loop (3) so as to allow the master station (4) to send data to a personal computer (5) and receive data therefrom. The input stations (1) and the master station (4) are interfaced using a high-level data link controller and the master station (4) is interfaced with the personal computer (5) at using a serial interface link constituted by an asynchronous communications interface adapter.
