Abstract

PURPOSE:To make a feeding cable needless and make the automatic gathering of terminal data and the remote centralized control efficient by using a common transmission path between a master station and a slave station to charge the battery of the slave station in time division. CONSTITUTION:In case that code information is transmitted from computer MPU to data terminal equipment TM, common transmission path L is short-circuited by a transmission pulse signal to change the transmission path potential by a prescribed quantity in master station PS. In pertinent slave station CS, the potential change is detected to obtain receiving signals and supply them to terminal equipment TM. The data transmission between slave station CS and master station PS is performed in the same manner. Meanwhile battery E of the slave station is charged from power source E through transmission path L while utilizing an idle time of data transmission. These data transmission and slave station power source charge are controlled by control parts CR of master and slave stations.
