Claims

[Scope of utility model registration request]

The main operation panel and multiple terminal devices are connected to each other via a pair of signal lines, and the address signal, control data signal, and long pulse signal for waiting for return are sent in series from the main operation panel to each terminal device. The signals arranged on the line are transmitted cyclically for each address, and each terminal has an address judgment means that compares the address signal on the signal line with its own address, and a control output according to the control data signal when the address signals match. A control output means that generates a signal and a monitoring signal return function that returns the monitoring signal as a return current to the main operation panel by short-circuiting the signal line through an appropriate impedance during the period of the long pulse signal for return standby. A remote control system comprising: a wireless transmitter for transmitting address signals and control data signals of arbitrary terminals as serial data; a receiver for receiving signals from the wireless transmitter; and a receiver for receiving signals from the wireless transmitter; A shift register converts the serial data output from the converter into parallel data and latches it, the address signal latched in the shift register is used as its own address, and the control data signal latched in the shift register is used as a monitoring signal to be sent to the main operation panel. A wireless terminal consisting of the terminal to be sent back is connected to the signal line, and the monitoring signal sent back from the terminal to the main operation panel is transmitted from the main operation panel to each terminal as a control data signal following the address signal of the terminal. A remote control system characterized by transmitting data.
