Abstract
Home-Network is an integrated network of the PC and all electric home appliances in the home so that they can communicate with each other. In the 21th century, here are various technology for Home Network environment such as HomePNA, IEEE 1394, Ethernet Lan and Bluetooth. For Home Network construction, generally, the standard series interface 'RS232' is used to make communication possible between electric home appliances. However Home network using RS232 has a problem. That is, All machines have to be connected to each other with RS232 using Point-to-Point mode. In this case, the system becomes complicated because we have to use circuits as much as there are machines and increased expenses. To improve this problem, In this thesis, designed home network using RS422 Multi-drop mode serial communication and controled it with embedded linux system. And connected RS422 with motors and sensors using PIC to make the home network virtual environment.
