The direct way to configure a XBee radio module (Series 1) is to use AT commands over serial.
* Open your serial console/terminal (Zterm, goSerial, screen on OSX, Putty or HyperTerminal on Windows). If you use the modules from the Interaction Workshop, the baud rate is 19200. If you use brand new modules, the default value is 9600.
+++ is instruction to enter command mode. Note that all AT commands with be confirmed with the string OK sent back by the module. If you don't get an acknowledge, you have to wait a couple of seconds and start again from the beginning with +++
Restore configuration to defaults, not necessary but advisable as older configuration could conflict.
Set the Personal Area Network (PAN) ID. Change ID if you want to create your own network. (16 bit, 0 - 65535 in decimal)
Set the module ID address. Must be unique (16 bit, 0 - 65535 in decimal)
Sets the destination address to broadcast to the whole PAN network.
Set the interface data rate to 19200. BD3 is the default with 9600.
Write the changes/settings to memory
Exit command mode
