Abstract
PURPOSE:To prevent any hindrance to transmission/reception of a data of other transfer equipment by stopping the operation of a transmission driver circuit based on a transmission stop signal outputted from a time supervisory circuit if a transmission time exceeds a prescribed time or over and a transfer equipment causes a transmission error thereby suppressing data communication. CONSTITUTION:A time monitor circuit 9 is provided, which outputs a transmission stop signal if a transmission time exceeds a prescribed time or over after a transmission start signal outputted from a transmission/reception controller 2 is received. Then a stop circuit 11 stopping the operation of the transmission driver circuit 4 based on the transmission stop signal so as to suppress the data transmission and alarm means 15, 18, 19 operated by a transmission stop signal are provided. Thus, if the transmission time exceeds a prescribed time and a transfer equipment causes a transmission fault, the operation of the transmission driver circuit 4 is stopped quickly to suppress the data communication and the alarm means 19 is operated to inform the occurrence of the fault to the operator. Thus, the hindrance to the transmission/reception of the data of the other transfer equipment is prevented.
