CONTROL SYSTEM FOR TERMINAL DEVICE CONNECTION

摘要

PURPOSE:To connect N sets of terminal devices of one system to other systems, by connecting line controllers connected to N sets out of a pluraity of terminals provided at a terminal controller in an electronic computer system via communication lines. CONSTITUTION:A terminal device 14 and controlers 15 and 15' for line 1 terminal are connected to central processing units 11 and 11' of each computer system via totallizator controllers 12 and 12'. N sets of terminal devices 14' and 14'' are connected to line/terminal controllers 15 and 15' and they are mutually connected via a communication line 16. The line/terminal controllers 15 and 15' are incorporated with a switcher which switches the line/terminal controllers either totallizator controllers 12 and 12' or terminal devices 14 and 14'. Thus, the terminal devices 14 and 14' are connected to central processors 11 and 11' mutually via the communication line 16.
