PROBLEM TO BE SOLVED: To allow the transmitter to be restored after a prescribed processing without immediately automatic restoration when a transmission error is solved by keeping an output corresponding to an error state till a reset signal is given to a reset terminal. SOLUTION: On the occurrence of a transmission error such as unable transmission of a signal due to a broken transmission line or a largely deformed signal waveform due to a strong noise in an output unit 2, it is detected and an error signal is outputted from an error terminal 20 and outputs from output terminals 70 -715 are latched before the occurrence of an error or all lines are interrupted (OFF) to provide an output corresponding to the error state and the output corresponding to the error state is kept till a reset signal is given to a reset terminal 21. That is, when the transmission error is eliminated, the transmitter cannot immediately and automatically be restored. |
