A communications device is coupled to a network and a device such as a CD player or the like. The communications device includes a network interface unit , a network controller communicating with the device and others, and a CPU controlling these components. Furthermore, the network interface unit , a transmission signal processing unit and a reception signal processing unit converts the data format appropriate for the network controller and the network , respectively. A transmission scheme determination unit determines the transmission scheme used among nodes. First and second switches and each have a contact A and a contact B, connecting either one of these contacts based on a control signal from the transmission scheme determination unit
