Abstract
A power supply apparatus is connectable to a common communication line together with at least one other apparatus. The power supply apparatus includes a communication interface and a controller. The communication interface is configured to transmit a signal indicating the presence of the power supply apparatus to a first apparatus connected to the power supply apparatus among the at least one other apparatus and to receive a signal indicating the presence of a second apparatus from the second apparatus connected to the power supply apparatus among the at least one other apparatus. The controller is configured to determine whether the power supply apparatus is connected to an end portion of the common communication line, based on whether the communication interface has received the signal indicating the presence of the second apparatus.
