PURPOSE: A parallel communication device is provided to perform parallel communications by connecting a master with a plurality of slave devices without a dialing code specifying function through a communication network. CONSTITUTION: A plurality of switches control communication lines which are respectively connected with two or more slave devices(200). A control unit(310) receives communication data including destination information from a master device(100). The control unit controls the switch to transmit the communication data to a specific slave device corresponding to the destination information. The control unit outputs a control signal to the switch in order to activate the communication line which is connected to the specific slave device. The control unit comprises a first receiving terminal receiving the communication data which is transmitted from the master device and a first transmission terminal which transmits the communication data to the slave device through the communication line.
