Example: Suppose an IO sample is received with analog and digital IO, from a remote with a 64-bit
address of 0x0013A200 40522BAA and a 16-bit address of 0x7D84. If pin AD1/DIO1 is enabled as an
analog input, AD2/DIO2 and DIO4 are enabled as a digital inputs (currently high), and AD3/DIO3 is
enabled as a digital output (low) the IO sample is shown in the API example in the table above.
XBee Sensor Read Indicator
Frame Type: 0x94
When the module receives a sensor sample (from a Digi 1-wire sensor adapter), it is sent out the serial port
using this message type (when AO=0).
