Abstract
PURPOSE:To achieve simultaneous control on real time, by connecting all lines at the same time in addition to the remote monitor control operation, in a line connecting circuit of a remote monitor control system using wire lines. CONSTITUTION:In addition to the operation selecting only one of switches 31-3n corresponding to wire lines 11-1n through the control of a switch control section 4, the connection of the remote monitor control is changed to the switches 31-3n to be opened and switches 41-4n, 7 to be closed. Thus, control codes from a modulation and demodulation section 5 are transmitted to all slave stations connected to the wire lines 11-1n.
