Title: COMMUNICATION ADDRESS DETECTION APPARATUS, CONNECTOR WITH BUILT-IN CONTROL CIRCUIT, AND COMMUNICATION ADDRESS DETECTION METHOD
Abstract:
A communication address detection apparatus, connector with built-in control circuit, and communication address detection method, wherein abnormal operations can be prevented even in cases when the voltage level to be input to any one of a plurality of communication address setting terminals has inverted due to a fault. The communication address detection apparatus detects communication addresses according to combinations of voltage levels of high or low levels input to the plurality of communication address setting terminals. In this apparatus, each combination of voltage levels with the assigned communication address stored in a communication address information storing means (172) is set so that, when any one of the voltage levels in that voltage level combination has inverted, the combination becomes a combination of voltage levels that has no assigned communication address.
