Abstract
PURPOSE: To make it possible to set up displays on plural display devices from one position by providing the remote display device with a demodulating means for selecting a monitored signal and detecting a display data pulse and a counting means for counting the display data pulse. CONSTITUTION: Each display device 2 consists of a frequency selection part 21 for selecting a modulated signal having its inherent frequency an amplifier/detection part 22 for amplifying and detecting (demodulating) the selected modulated signal and extracting a display data pulse, a counter part 23 for counting up the display data pulse, and a display part 24 provided with a liquid crystal display device (LCD) or the like and capable of decoding respective lines of the counter part 23 and numerically displaying the decoded results. A cable 31 is connected between an output matching unit 17 in a central control device 1 and an input matching unit 32 arranged near a display device group and a modulated signal is matched with the impedance of the high frequency cable 31 by the matching unit 17 and transmitted to a remote place. Connection from the unit 32 to frequency selection parts 21 in respective display devices 2 is branched by a signal feeder line 33. Thereby the modulated signal is matched with receiving side impedance by the unit 32 and simultaneously inputted to respective frequency selection parts 21.
