An interface device for managing game machines of an arcade by using a PLC(Power Line Communication) mode is provided to control the game machines remotely without installing communication lines, realize security better than an RF(Radio Frequency) or IrDA(Infrared Data Association) mode, and complete setting by inserting a plug into a receptacle. A master interface(120) converts requested/received information into a communication signal and inputs/outputs the communication signal by connecting to a management computer(110). A power line(130) transfers a power and communication signal at the same time by connecting to the master interface. A slave interface(140) converts the requested/received information into the communication signal and inputs/outputs the communication signal by connecting to the power line. A game machine computer(150) transmits deposited cash information and withdrawn certificate information according to a request signal by connecting to the slave interface. The master and slave interface comprises a coupling transformer, a modulator/demodulator, an MPU(Micro Processor Unit), an external I/O(Input/Output) interface, and a modem.
