Getting started with XBee Industrial Gateway
Joining ZigBee networks

initialized, the coordinator and routers can allow other devices (other routers or end devices) to join
the network and route data.
Each network is defined with a unique PAN identifier (
PAN ID
). This identifier is common among all
devices of the same network. That is, devices on the same ZigBee network must share the same PAN
ID in order to communicate with each other. When you power on a coordinator, it automatically
establishes the PAN ID or uses a pre-configured one when it creates the new network.
n
If the PAN ID of the coordinator is 0, it performs a PAN scan to identify nearby ZigBee networks
and uses a random unused PAN ID to start the new network. By default, an XBee Industrial
Gateway coordinator is configured to generate a random PAN ID.
n
If the PAN ID for a router or end device is 0, it performs a PAN scan and tries to join any
available ZigBee network it finds.
You can connect to an XBee ZigBee module that is configured as a router node to the network
initialized by XBee Industrial Gateway. By default, the PAN ID of this ZigBee module is configured to
0
.
Therefore, if you power on the XBee ZigBee module and there is no other ZigBee network around, the
module joins the ZigBee network initialized by XBee Industrial Gateway automatically. The joining
operation occurs when the Association LED of the board on which the XBee ZigBee module is mounted
starts blinking.
The 802.15.4 PHY (physical layer) protocol description defines 16 operating channels in the 2.4 GHz
frequency band. Before starting the network, the coordinator automatically performs a channel scan
to select a good channel to use for the network.
You can configure all the ZigBee nodes in a network with the channel or channels on which they
operate.
Joining XBee Industrial Gateway to an existing ZigBee network
Although this is not a common task, you can configure your XBee Industrial Gateway device to operate
as a router and join an existing ZigBee network.
To join XBee Industrial Gateway to an existing ZigBee network:
1. Open a web browser and type the URL of XBee Industrial Gateway:
http://192.168.100.1
. The
XBee Industrial Gateway web interface appears.
2. Click
XBee Network
in the left menu.
3. Select the XBee Industrial Gateway ZigBee local XBee device. The
XBee Configuration
page
appears.
4. From the
XBee Configuration
page, click
Network Settings
.
