Abstract
To provide a serial communication system that can flexibly or easily change a system configuration. For example, when coupled to first and second serial buses, a motor module transmits a first signal to the second serial bus. Subsequently, the motor module transmits a first command containing a candidate address to the first serial bus; meanwhile, the motor module searches for an address where an acknowledgement is not received in response to the first command. The motor module transmits the search result address to the second serial bus. A control unit at the reception of the first signal changes to a sleep state that stops communications with the first serial bus and receives an address as a search result from the second serial bus.
