The controller is based on the hardware of the Arduino physical computing controllers. It can be programmed as a stand-alone controller using the free, open source Arduino environment. Internally, the controller is “shield compatible”, allowing the use of many extension boards designed for the Arduino Deumilanove. As shipped the controller is loaded with a sketch that receives simple commands over the USB or RS485 serial port and switches relays or responds with the status of inputs.
Multiple controllers can be connected to one or more PCs in an RS485 network. Each controller can be assigned an address and will respond to commands addressed to them.

|An example program has been written in both Visual Basic 6 and VB .Net to show you how to interface with the KTA-223 using a PC.|
Light Flasher Software
Our Light Flasher software for the KTA-223 allows you to sequence the relays in patterns. This is designed for Christmas lights, trapshooting and other simple time loop controls.
Time Clock Software
Our Time Clock software for the KTA-223 called Time-Clock allows you to switch on relays at certain times of the day and days of the week. Can be used to control lighting and watering for plants, etc.
