<p>PROBLEM TO BE SOLVED: To solve the problem of the cost increasing in conventional cases, because the control function and the communication function are implemented entirely by one IC and the IC is replaced for a different communication protocol. SOLUTION: A communication IC 24 is separated from a control IC 30, and for a different communication protocol, the communication IC 24 is replaced by other communications IC, corresponding to different communication protocols.</p> |
