Abstract

A remote control device comprises a wireless interface that transmits data to and receives data from a target device that is to be controlled by remote control device. A user input interface generates user commands based on user inputs. A control module receives the user commands and wirelessly transmits the user commands to the target device via the wireless interface. A target device comprises a wireless interface that transmits configuration data to and receives commands from a remote control device. A control module receives the commands and that adjusts operation of the target device based thereon. A user input interface locally adjusts operating of the target device.
