<P>PROBLEM TO BE SOLVED: To provide a communication module and the like in which ID registration can be executed in a simple and easy manner. <P>SOLUTION: The communication module 200 includes communication terminals 221, 223, a signal transfer control means 227, a processing section 228 and a memory 229. The signal transfer control means 227 can switch a downlink signal passing state where a downlink signal SD input from the outside of the module to the prestage-side communication terminal 221 is passed to the poststage-side communication terminal 223, and a downlink signal blocking state where the downlink signal SD is blocked from being transferred to the poststage-side communication terminal 223. The downlink signal SD includes a signal of an ID registration instruction transmitted from a main unit 100. The memory 229 stores an ID assigned to the communication module 200. The processing section 228 receives the ID registration instruction in the downlink signal blocking state and changes the downlink signal blocking state to the downlink signal passing state by controlling the signal transfer control means 227 after reception of the ID registration instruction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
