COMMUNICATION MODULE AND ELECTRIC APPARATUS EQUIPPED WITH COMMUNICATION MODULE

摘要

PROBLEM TO BE SOLVED: To inform a communication margin related to S/N ratio in communication and information for analyzing a cause only with a communication module or an electric apparatus incorporating or attached with the communication module in electric lighting line communication.

SOLUTION: The communication module 5 comprises an error correcting section 10 of received data, and a means 15 for displaying information concerning presence of error data in received data at the error correcting section. Such a case as reception is successful but S/N ratio margin for demodulation is insufficient can be informed, and a communication module or an electric apparatus provided with the communication module can predict a position where communication trouble occurs possibly and determine a countermeasure.
