2 Introduction
This highly integrated wireless communication module, embeds all of the necessary
components to perform a virtual plug and play function for ZIGBBE RF transceivers.
The module contains many of the necessary features required to built a reliable RF
communication network such as;, anti-interference ability, support for multiple network
topologies including self healing features, point to point, or point to multipoint
configuration which can be composed as star, tree, mesh tree network structure and of
course low power modes. .
The module is divided into a center coordinator, routers and end nodes, these three
distinct modes of operation provide the user with the option for different network
Structures that can be optimized for the particular application. The center of the network
is the coordinator node which is responsible for launching the network’s organization,
network maintenance and management, The data router function built-into the device,
which is responsible for transferring the data within the Zigbee network to the
coordinator and eventually to the host. The terminal nodes are typically at the end of the
network and typically perform the sensing and data acquisition function.
The coordinator, routers and end nodes configured by software commands. .

4 Product performance
4.1.1 Low power consumption
This module can be configured in a variety of energy-saving modes, in which it is possible to
have a fully operational system run for more than 6 months on two AA batteries.
4.1.2 Network self-organization, self-healing ability
The Network configuration features of this module will allow the self-organizing of the network
without human intervention. The network’s nodes can sense the presence of other nodes and
determine the connection between composition and structure of the network;
The self-healing function can change the order in which data traverses through the network to
compensate for a change in node position, or node failures, etc. Low cost
This Zigbee module operates in the unlicensed ISM band at 2.40 GHz~2.48GHz and comes with
royalty-free firmware thereby yielding an extremely low cost system solution.
4.1.3 Network capacity
The specification for Zigbee network does allow for up to a maximum of 65,534 nodes in the
particular network. The Zigbee module can be configured to communicate via a standard serial

data (RS232 data) via the UART interface, and the firmware will allow you to transmit broadcast
messages to the other devices in the network. Any module in the network can be queried from the
coordinator to determine it operational mode and its relative position within the network.

7.1 Mode switch port
Input/ output port PIO_01 is configured as a mode switching port. When the module is controlled by an
external microprocessor switching this pin will allow the user to switch between the normal operation
running mode and the command mode. When the mode pin is set to a logic low level “0” the module is in
the active, operational mode. When the mode pin is set to logic high state “1” then the module is in
configuration parameters. See table below for a summary.
Mode pin State Operational state
Logic low Zigbee network operational MODE
Logic high Command mode

This Zigbee wireless module has allocated two PIO to operate as status LED indicators. The
instructions were operational mode (pin 13 ÆP10), and the network indication (pin 12 ÆP11), the two (2)
LEDs indicate status and are described in the following table:

wire + ground UART connection (TX, RX, RTS, CTS, GND ) or a two (2) wire +ground UART
connections (TX, RX, GND)
The default data interface parameters:
Serial port parameters Default
Baud Rate 9600
Parity NONE
Data bits 8
Stop bit 1

7.4 Configuration Interface
When the ZIGBEE wireless communication module MODE switch pin (PIO_01) pin is
connected high, the system enters the command mode; low on this pin will shift the module’s
operating mode to the operational mode. .
The command mode will only accept command at a fixed communication setting as outlined in the table
below.

8 The UART
The module provides four-wire+ Ground serial asynchronous communication interface;
The following diagram shows the TXD, RXD, CTS, RTS signals for the UART and the direction of the
data flow. The voltage levels of the UART are low= 0 Volts and Hi = Vdd (3.3Volts). For two (2) wire +
Ground operation do not connect CTS and RTS.

0) Broadcast Mode: When operating the broadcast mode; each of the nodes in the network will be able to
receive the broadcast message.
1) Master-slave mode: When operating in the Master Slave mode the serial data is sent to the central
coordinator. The other nodes in the network simply act as a pass through and do not actually receive the
serial data. The Serial Data terminates at the Central coordinator.
2) Point to point Mode: When operating in point to point mode: the node must format the data as outlined
below, such that the serial transmit and receive data are properly interpreted. (See below for the specific
point to point data format )
