Abstract
PURPOSE:To prevent installation environment from being limited unnecessarily by connecting input/output signal lines between both electronic computers by a photocoupler. CONSTITUTION:In setting control output lines 6, 7, control input lines 8, 9 are set and power is supplied through the signal line 6 to diodes 26a, 26b and a photocoupler 24. In giving a positive potential to a negative terminal of a transmission data line 10 and ground potential to a positive terminal in this state, a current flows to a photocoupler 23, the positive terminal of the reception data line 13 at the electronic computer 2 does to a ground potential, the negative terminal is kept to a potential higher by 1V than the ground terminal 22 and the polarity of the reception data line 13 and the line 10 is the same. In sending a data from the computer 2 to the computer 1, the equipment is operated similarly to above.
