A remote controller accesses via a connection control data from an appliance to be controlled. The remote controller includes a connection interface, a control unit, an input keypad and a remote signal output unit. When a user intends to remotely operate the appliance, first the connection interface needs to be inserted to a connection slot of the appliance, allowing the control unit to read the control data for remotely controlling the appliance. Then, when the user uses the input keypad to operate a function of the appliance, the control unit transmits an operational instruction from the input keypad and the control data to the remote signal output unit where a control command is generated and transmitted to the appliance such that the appliance can execute the function corresponding to the control command.
