<p>PURPOSE:To save power at a terminal equipment, to miniaturize the terminal equipment and to increase the number of external equipments connectable to respective terminal equipments. CONSTITUTION:Respective terminal equipments 6 are equipped with control parts and therefore, respective first and second enabling signals based on a select signal are inputted to each input part 9 and transmission part 7 so as to permit the input and transmission of each state signal. When the state signal has a delay characteristic, the first enabling signal is turned on based on the ON of the select signal to the terminal equipment 6 preceding only for a prescribed number reversely to a select order from the corresponding terminal equipment 6, and turned off based on the OFF of the select signal to the corresponding terminal equipment 6, and the second enabling signal is synchronous with the select signal to the correspondent terminal equipment 6.</p> |
