Abstract
Abstract A data setting system for terminal units by means of an optical wireless signal includes in the respective terminal units a data storing means and a receiving means for the optical wireless signal and, in a data operating device separate from the terminal units, an operating means for preparing and transmitting a setting signal to the terminal units. The data setting for the respective terminal units employed in a remote supervisory and controlling system with a multiplex data transmission utilized is thereby made attainable at a remote position from the terminal units through the optical wireless signal.
