Title (EN) OPTICAL TRANSMISSION OF SERIAL DATA
(FR) TRANSMISSION OPTIQUE DE DONNEES SERIE
Abstract:
(EN) Accessory for a laptop computer (102) with LCD display which is connected (152) to the laptop serial communications port and optically transmits data (156) to a portable information device, such as a wristwatch (12) designed to receive data (13) as sequential pulses of light. The accessory includes a microcomputer (170) with an RC timebase which is calibrated each time it is used by a special internal program (fig. 10), so that the input baud rate to the accessory matches the communications baud rate of the data received from the laptop. The internal program also permits selection of an output baud rate for the optically transmitted data.
(FR) La présente invention concerne un accessoire pour ordinateur mallette (102) disposant d'un écran à cristaux liquides qui est connecté (152) au port de communications série de l'ordinateur mallette et peut transmettre des données (156) à un dispositif portatif d'informations tel qu'une montre-bracelet (12) conçue pour la réception de données (13) par impulsions lumineuses séquentielles. Ledit accessoire comprend un microprocesseur (170) disposant d'une base de temps RC constante qui est étalonnée chaque fois qu'elle est utilisée par un programme interne spécial (Fig. 10), de sorte que le débit en bauds d'entrée vers l'accessoire corresponde au débit en bauds des communications des données reçues de l'ordinateur mallette. Ledit programme interne permet aussi la sélection d'un débit en bauds de sortie pour les données de la transmission optique.
