A control method of a show case is provided to prevent the communications barrier in advance by automatically resetting the power in the remote using software. A control method of the show case comprises following steps. The communication connection with each controller equipped in a plurality of show cases is performed(S101). If the communication is made, the communication state is detected and analyzed according to each controller(S103,S105). If the analyzed result has the communication barrier possibility(S107), the power source reset indication is produced(S109) so than the power source of each controller is reset remotely. The power reset data is provided to the controller having the communication barrier possibility(S111). The communication connection is made with each controller in which the power is reset(S113). If the time data is requested from the connected controller(S115), the current reference time data is transmitted to the connected controller on a real time basis(S117).
