Wireless Control

Application Kit

Kit Description

The Wireless Control Application Kit provides a reference to interface a license-free 900 MHz or 2.4 GHz wireless data module to a new or existing Rabbit-based embedded system.

The Wireless Control Application Kit comes with samples, libraries and hardware to integrate low-cost wireless connectivity operating at frequencies of either 900 MHz or 2.4 GHz with a Rabbit device. The kit contains one Rabbit single board computer and two Digi RF modules for full application reference, which can also serve as a template for a robust wireless implementation where a serial connection is required. The Wireless Control Application Kit offers a serial connection alternative where wired cables are not practical to use as well as exemplifies the versatility and simplicity of adding wireless connectivity to an embedded application. Applicationsinclude simple remote monitoring, proximity sensor readings, wireless I/O control, and data transmission.

The kit contains a low power LP3500 single board computer with a power-save mode that draws less than 100 µA, 26 industrialized I/O, 8 A/D inputs w/ programmable gain, 6 serial ports and available keypad/display peripherals. It is then partnered with your choice of a low-cost 900 MHz 9XCite module featuring over-the-air throughput data rates up to 38.4 Kbps or the longer range 2.4 GHz 24XStream module with range of up to 3 miles (outdoor RF line-of-site) with the appropriate antenna.

A Modbus master PC application allows the user to control the single board computer as a Modbus wireless slave device, and it is designed to be easily portable for other ModBus slave devices. This allows any standard Modbus wired/wireless serial master application to control and monitor the digital and analog I/O in near real-time. In addition, we have implemented a PPP Host/Client direct wired/wireless connection to demonstrate how to use Point-to-Point Protocol (PPP) to make a direct connection over a wireless serial port. Using a direct PPP connection allows wired/wireless serial devices to utilize common protocols like HTTP, FTP, SMTP, POP3, etc. This can be especially useful for devices that only have serial interfaces and no Ethernet and/or WiFi. Using our RabbitWeb software module, the LP3500 can serve web pages accessible from to offer accessibility from the Internet.
