/*
This example is for Series 1 XBee Radios only
Receives I/O samples from a remote radio with 16-bit addressing.
The remote radio must have IR > 0, at least one digital or analog input enabled
and DL set to the 16-bit address of the receiving XBee (the one connected to the Arduino).
 
This example uses the SoftSerial library to view the XBee communication.  I am using a 
Modern Device USB BUB board (http://moderndevice.com/connect) and viewing the output
with the Arduino Serial Monitor.
