Wireless control application kit for remote monitoring and control

4 April 2007 Computer/Embedded Technology

Rabbit Semiconductor has introduced the Wireless Control Application Kit which provides a development reference to interface the licence-free 900 MHz or 2,4 GHz wireless data modules from MaxStream to a Rabbit-based embedded system.

The system illustrates the versatility and simplicity of adding wireless connectivity to embedded applications such as remote monitoring, proximity sensor readings, wireless I/O control, and wireless data transmission.

The Wireless Control Application Kit contains a proven low power Rabbit LP3500 single board computer, and two MaxStream RF Modules. The Rabbit LP3500 single board computer has 26 I/O, eight analog input, six serial ports and a power save mode that draws less than 100 μA.

The 900 MHz application kit features the OEM XCite RF modem from MaxStream, intended for US applications, while the 2,4 GHz application kit features the extended range XStream RF modem for projects worldwide. Both modems are functional replacements to a serial cable, so developers can do away with cumbersome hard-wired solutions.

Sample programs and libraries are designed for quick out-of-the box development. A Modbus master PC application allows the user to control the single board computer as a Modbus wireless slave device. In addition, the PPP Host/Client direct wired/wireless support was developed to help demonstrate how to use common protocols like HTTP, FTP, SMTP, and POP3 over a wireless connection. These added protocols allow the LP3500 to serve web pages or to be able to send data to an FTP server for remote data-logging.
