Abstract

PURPOSE:To immediately report the initialization completion of a remote controller separated by several Km or more without causing a malfunction due to a noise at the time when a power source is turned on by a small hardware quantity by reporting the initialization completion of the remote controller to a central processor equipment. CONSTITUTION:A channel 1 executes a transfer of date to a remote controller 2 through an optical fiber 3. An initialization completion frame from the device 2 is received by the channel 1, and when its detection value reaches a prescribed value in a detecting circuit 14, a detecting signal 203 is sent to a data transfer control circuit 15. The circuit 15 sends a report instructing signal 204 to an initialization reporting circuit 11, and also, sends a sending-out instructing signal 202 to a frame sending-out circuit 17. In such a way, the circuit 11 reports the initialization completion to a central processor equipment through a receiving data buffer 10, and the circuit 17 stops sending out the initialization completion frame to the device 2.

Because a unique frame is sent, the completion of initialization of the remote control device is not correctly notified.

Additionally, if the remote controller is powered up later than the channel, and as before, if the remote controller powers up and sends noise down the optical fiber and that noise is a frame specific to the response, the channel will mistakenly This method has the disadvantage that the device is notified that the initial settings of the remote control device have been completed.
