Xbee Pro S1 Analysis

XBee Pro S1 is used for wireless transmission of data over terrestrial or underwater. XBee is short range with low data through put wireless communication system. It is used for point-point or multipoint transmission with UART (Universal Asynchronous Receiver/Transmitter) interface. XBee Pro S1 belongs to a popular family XBee. Asynchronous means that data is transferred without support from an external clock. Data bit can be sent at any point. Start and stop bits are used between data bytes to synchronize the transmitter and receiver. It is most cost effective method.RS 232 Logic operates -13v to -5v indicate a data bit of value 1.For +5v to +13 v indicate a data bit value 0. In TTL logic 0 to 0.8 indicate a data bit zero and 2v to 5v indicate high data bit 1.A UART is a block of circuitry responsible for implementing serial communication. One end of the UART is a bus of eight or so data lines on the other is two serial wires- Rx and Tx. XBee Pro S1

AT mode is synonymous with "Transparent" mode. In AT mode is
XBee explorer USB is easy to use. USB to serial base unit for XBee Pro S1 line. Plug the unit into the XBee Explorer, attach a mini USB cable, and will have direct access to the serial and programming pins on the XBee Pro S1 unit. The highlight of this board is an FT231 USB-to-Serial converter. In this way translates data between computer and the XBee Pro S1. There’s also a reset button, and a voltage regulator to supply the XBee Pro S1 with plenty of power. In addition, there are four LEDs that’ll help if ever need to identify and remove errors the XBee Pro S1: RX, TX, RSSI (signal-strength indicator), and power indicator. Includes an onboard 3.4V / 500mA voltage regulator to supply sufficient power for the high power 60mW XBee Pro S1 radios. XBee explorer USB can be used as XB evaluation (XCTU software compatible). By using this define protocols of various XBee’s via XCTU
