Creating a Custom Interface for X10 Home Automation Joey Grover April 2 2010 EXECUTIVE SUMMARY Home automation control is an area that is nearly endless in possibilities However most software that is designed for home automation is limited and doesn t provide desired features to the user This application note discusses the basics of home automation with X10 modules and shows how to create a simple form that will allow the user to control the X10 home automation modules KEYWORDS Home automation X10 firecracker CM17A Table of Contents E lg na a ea E ssp bat ea eo E el aware be Ala 2 Background taa O A 2 21X10 ODE EINEN a ico a Eege Pale ej 2 LALO APA Ai eege RU SS a a ai 2 2 3 o EE EE 3 Required Components Jus intima dnd ne be aa ka ene aa 5 AULA A A ad 7 Step 1 Create a New Form a 7 Step 2 Make the Interface ad 7 Step 3 Add Serial Communication rien 8 Step 4 Setting Up the Code nacida a 9 Step 5 Install X10 Modules coccnococccccccncccnnononononnnnnnnncnnnnnnnnnnnnnnncnnnns 11 Step 6 Home Automation ri eo ii 11 E 12 Dese UCT o WEE 12 ROTOS RE A SAA 13 APPEAR 14 1 Introduction Home automation gives consumers the ability to control their appliances without having to be physically near them The control can come from either hardware or software based applications The provided software suites usually limit consumers on what can be achieved This application note will discuss the
17. ability to set up and create a basic interface for home automation using X10 modules 2 Background 2 1 X10 Operation The interface that will be described will use the X10 units for home automation The X10 Firecracker RF module will send signals to a plugged in X10 Transceiver that will then use power line carrier PLC communication to send signals to other X10 units plugged into different outlets Each unit is assigned a house code and unit number this is done on a set of dials on the unit 2 2 X10 Firecracker The X10 Firecracker does not send a signal like a normal serial output Instead of using the dedicated data lines it uses the RTS and DTR pins on the serial port This allows a second serial device to be connected onto the firecracker as long as the second device does not need the RTS and DTR pins The Firecracker is powered by keeping either the RTS or DTR line high or logical 1 When communication is done it takes place in the following manner Signal RTS DTR Reset 0 0 Logical 1 1 0 Logical 0 0 1 Standby 1 1 One important note is that when trying to send a signal through firecracker unit either the RTS or DTR lines needs to remain high to ensure the signal gets sent and the unit isn t reset This is ensured by allowing a 5ms delay between signals A typical signal would look like this Standby 1 Wait 0 Wait 1 Wait RTS DTR Obtained from Firecrac
