<p>PURPOSE:To shorten the system starting time by omitting the connection processing to the unused terminal equipments. CONSTITUTION:Receiving an instruction signal SS from a CPU 10 for application of a power supply, a power controller 50 sends successively the start signals P1-Pn to the power units 31-3n. These units undergo the ON/OFF control with the signals P1-Pn only when the manual switches 41-4n are kept ON. Thus the units 31-3n are actuated and also send the start end signals Q1-Qn to the controller 50. The controller 50 sends a signal ST to a CPU 10 to show a terminal equipment that receives receiving the supply of power. The CPU 10 applies the connection processing only to the terminal equipments receiving the supply of power in response to the signal ST among those terminal equipments 21-2n.</p> |
