COMMUNICATION DEVICE, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

Provided is a communication device capable of transferring serial data transmitted from serial communication equipment to a plurality of communication devices. Said communication device is, for example, a PLC modem (100M) which communicates with another PLC modem (100S), and is provided with a serial interface (13) which receives serial data from a serially connected concentrator (810), a control unit (11) which modulates the received serial data to data other than the serial data to generate transmission data, and a PLC interface (12) which performs first unicast transmission in which a PLC modem (100S1) is designated as a transmission destination and the transmission data is transmitted thereto and second unicast transmission in which a PLC modem (100S2) is designated as the transmission destination and the transmission data is transmitted thereto.
