Introduction: As the name of the project suggested we are making RS 485 based LAN N/W using micro controles 9C 89c51 this is general purpose project which has many application. Our project mainly concerned with RS 485 based LAN for controlling the appliance & sending small message on lan simultaneously.

As the name of the project suggested we are making RS 485 based LAN N/W using micro controles 9C 89c51 this is general purpose project which has many application. Our project mainly concerned with RS 485 based LAN for controlling the appliance & sending small message on lan simultaneously.
In our project we use two sections. One is transmitter & other is receivers section. Transmitter section placed with PC & receiver section up to 1km. In transmitter section 51 called master IC interface with RS 232 & RS 485 it take data from PC & send it to slave. Receiver section contains lan & relay driver with 51 called slave IC. It takes data from master IC via RS 485 & according to internal programe slave control the appliance via relay drives.
