Document Type and Number:
Japanese Patent JP2573873
Kind Code:
B2
Abstract:
PURPOSE:To recognize the state of a remote controller momentarily by receiving a specific frame from the remote controller after the end of initial setting, displaying the state of the remote controller in response to the reception and resetting a remote controller state display means when a fault is detected. CONSTITUTION:When the power supply of a channel device is applied and initial setting is finished and the power of a remote controller 2 is applied and the initial setting is finished, an initial setting end detection circuit 104 sends an initial setting end signal 401 to an idle frame generating circuit 103 to instruct the generation of an idle frame. When an idle frame detection circuit 14 detects an idle frame, the circuit 14 sends an idle frame detection signal 302 to an AND circuit 16 and a data transfer control circuit 19. Thus, a set signal 303 is generated to set a remote controller state display 17. When the power of the remote controller 2 is interrupted, a frame fault detection circuit 18 detects the error of the frame and the reset signal 304 resets the remote controller state display 17.
