<p>According to the present invention, a transmitter (103) transmits a signal having a current value corresponding to inputted data. Terminal resistors (105, 106, 202, 203) are provided between a power source and a reception terminal into which the signal transmitted by the transmitter (103) is inputted. A receiver (201) outputs data on the basis of the voltage value at the reception terminal. Controllers (107, 205) input a data pattern to the transmitter (103), and control the current value of the signal transmitted by the transmitter (103) and the resistance values of the terminal resistors (105, 106, 202, 203) on the basis of the data pattern and the data outputted from the receiver (201).</p> |
