Abstract
PURPOSE: To make it possible to simplify the transmission part of a terminal controller and the reception part of data input device by making connections via a data line for the transmission of character sequency and a signal line for the transmission of polarity.
CONSTITUTION: Terminal controller 1 is connected to data input devices 2, 3 and 4 via a data line 5 and signal line 6. Then, data line 5 is used for transferring control characters ABDC, BCDE and FGHI, and data from devices 2, 3 and 4 to units 1 as shown by (d), (e) and (f), and data reception part 11 receives a control character from data line 5 and informs signal transmission part 12 whether it is correct or not, thereby making the polarity of signals line 6 negative as shown by (c).
