Zigbee Modules ( Xbee | XBee –PRO)

The XBee 802.15.4 (formerly Series 1) OEM RF module is an IEEE 802.15.4 compliant solution that satisfies the unique needs of low-cost, low-power wireless sensor networks. It is easy-to-use, requires minimal power and provides reliable delivery of critical data between devices. Its small form factor saves valuable board space.


No configuration is necessary for out-of-box RF communications. The XBee module’s default configuration supports a wide range of data system applications. Advanced configurations can be implemented using simple AT commands.

3. XBee Board Details

Power Supply

The external power can be DC source only, with a voltage (+5V/,1A output) at 230V AC input. The LM1117 Fixed +3.3V positive regulator is used to provides power to the Zigbee Modules and other peripherals. Separate slide switch is provided to power the board (ON/OFF).


RESET

The Reset Switch is used to reset (re-boot) the RF module. This switch only applies when using the configuration tabs of MaxStream’s X-CTU Software


I/O & Power LEDs

LEDs indicate RF module activity as follows:


  • Yellow (top LED) = Serial Data Out (to host)
  • Green (middle) = Serial Data In (from host)
  • Red (bottom) = Power/Association Indicator (Refer to the D5 (DIO5 Configuration) parameter)

Serial Port

Standard female DB-9 (RS-232) connector.
Note : Male – Female 9-pin Straight cable (Rx-Rx | Tx-Tx)


RSSI Indicators

RSSI LEDs indicate the amount of fade margin present in an active wireless link. Fade margin is defined as the difference between the incoming signal strength and the module's receiver sensitivity.


  • 3 LEDs ON = Very Strong Signal (> 30 dB fade margin)
  • 2 LEDs ON = Strong Signal (> 20 dB fade margin)
  • 1 LED ON = Moderate Signal (> 10 dB fade margin)
  • 0 LED ON = Weak Signal (< 10 dB fade margin)

4. X-CTU Software

X-CTU is a MaxStream-provided software program used to interface with and configure Max-Stream RF Modules. The software application is organized into the following four tabs:


  • PC Settings tab - Setup PC serial ports for interfacing with an RF module
  • Range Test tab - Test the RF module's range and monitor packets sent and received
  • Terminal tab - Set and read RF module parameters using AT Commands
  • Modem Configuration tab - Set and read RF module parameters

Installation

Double-click the "setup_X-CTU.exe" file and follow prompts of the installation screens. This file is located in the 'software' folder of the MaxStream CD and also under the 'Downloads' section of the following web page: www.maxstream.net/support/downloads.php


Setup

To use the X-CTU software, a module assembly (An RF module mounted to an interface Board) must be connected to a serial port of a PC.


NOTE: Failure to enter AT Command Mode is most commonly due to baud rate mismatch. The interface data rate and parity settings of the serial port ("PC Settings" tab) must match those of the module (BD (Baud Rate) and NB (Parity) parameters respectively).


Serial Communication Software

A terminal program is built into the X-CTU Software. Other terminal programs such as "HyperTer- minal" can also be used to configure modules and monitor communications. When issuing AT Commands through a terminal program interface, use the following syntax: Figure . Syntax for sending AT Commands


syntax-for-sending-at-commands

 

NOTE: To read a parameter value stored in a register, leave the parameter field blank. The example above issues the DL (Destination Address Low) command to change destination address of the module to "0x1F". To save the new value to the module’s non-volatile memory, issue WR (Write) command after modifying parameters.
