"The wireless secured remote control system can be directly controls the devices through eight data lines from data register in PC via DB25 connector. The paper shows how to expand the data lines up to more than eight lines. The system is principally structured into hardware and software to show that the independent interface of more devices requires dependant software to drive the relevant devices. The hardware grouped into wireless network, PC, interfaced circuits and controlled devices. The usage of wireless network provides the system with user mobility while performing the control processes in addition to the ease of maintenance and other important issues."
