The CTX35 Gateway interfaces a CTX35 unit connected to the serial port to send X10 commands. X10 is a protocol to switch on and off lights and other appliances connected to the powerline. www.x10.com
You will need a CTX35 and at least one other X10 compatible unit have any usage of this library.
#Disclaimer This library is in an early stage. Currently it only supports sending commands through CTX35, not receiving messages from the powerline. I have only tested it on my own computer. I have not tested all kinds of scenarios and commands, so the stability is still in the unkown.
#Installation The installation instructions are meant as a quick start, and did work for me when I tested it. If you run into problems you should consult the documentation/support of the product you have problems with.
In short, you need a free serial port, rxtx installed in your jvm and you are ready to go.
If you are directly using your serial port on your computer you can skip this step. If you do not have an available serial port on your computer you should use a USB to serial device. Any USB-serial device should do. The installation procedure is for this product: USB to Serial RS-232 Adapter
I have not tested this myself, but all new distros are supposed to have support out of the box, just plug it in.
Rxtx is an API for communication with a serial- or parallel port in java. This is a provided dependency, and is expected by CTX35 api to be installed in your JVM.
Download link Note: Windows built in zip utility claims the file is corruped. It is not, just use a different program to unzip it. I have had success with total commander, but I guess others will also work.
put rxtxSerial.dll in jre\bin
put RXTXComm.jar in jre\lib\ext
put RXTXcomm.jar in /Library/Java/Extensions
put librxtxSerial.jnilib in /Library/Java/Extensions
Create the directory /var/lock, and add your user to the group uucp:
sudo mkdir /var/lock
sudo chgrp uucp /var/lock
sudo chmod g+w /var/lock
sudo dscl . -append /Groups/uucp GroupMembership $USER
Haven't testet this myself, read the README in rxtx download.
If you downloaded the source you could run the test Ctx35GatewayTest (change comport to where you installed the CTX35 device).
If you downloaded the jar (not yet released) you should run this code:
Ctx35Gateway gateway = new Ctx35Gateway();
gateway.setCommport("COM3");
gateway.init();
gateway.transmit(new Transmission(new Addressing('A', 9,10,11), Command.on));
If you would like to run the serial communication in a different thread and not have to worry about thread safety, wrap the gateway in an queued gateway:
Ctx35Gateway gateway = new Ctx35Gateway();
gateway.setCommport("COM3");
gateway.init();
QueuedCtx35Gateway queueGateway = new QueuedCtx35Gateway();
queueGateway.setX10Gateway(gateway);
queueGateway.init();
queueGateway.transmit(new Transmission(new Addressing('A', 9,10,11), Command.on));
