XBee Analog I/O Adapter

Configuring inputs and outputs
Input selection
Six control lines from the XBee module are used to place the four external
terminals into the desired input mode.
The power-on default is 0-10VDC on all four terminals.
Set the analog mode
The AT commands D8, D4, and D6 set the analog mode for terminals 1
and 2. P0, D7, and P2 set the mode for terminals 3 and 4. All other
configurations are invalid. A Python module named xbeeain.py is available
to set the analog mode; see pages 24 and 25.
