Turn on switch 22 (RS_485 connection high). After that, increase the ID by 1 to “2” and output the ID setting command to the RS-485 interface line 21.
- the slave unit 1 electronic equipment unit 2 to which the RS-485 interface line 21 is connected receives it, and its own RS-485 connection is low (switch 22 in Fig. 1 is off). It judges whether or not, and if NO, the process is terminated as it is. In this case, since it is YES, the ID “2” is set as its own ID, and an answer to the completion of the setting is output to the master unit. Then turn on its own switch 22 to bring the RS-485 connection high.
- the master unit Electronic equipment unit 1
- the slave unit increments ID by 1 again to “3” and outputs the ID setting command.
- slave unit 1 (electronic equipment unit 2) and slave unit 2 (electronic equipment unit 3) receive it. Since the RS-485 connection of the slave unit 1 is high, the slave unit 1 terminates without doing anything because the ID has been set.

- the master increments ID by 1 each time it receives an answer from the slave, and outputs an ID setting command. Then, among the slave units that have received it, switch 22 is off and the RS-485 connection is open, the slave unit sets its ID as its own ID, outputs an answer to the master unit, and then turns on switch 22. To bring the RS-485 connection high. Repeat this operation to set the ID for the master unit and all connected slave units, and receive the setting completion answer from the slave unit within a predetermined time after the master unit outputs the ID setting command.
