This section describes how to connect an Analog I/O Unit to the CPU Unit.
Setting the Averaging Function
DIP switch pins 1-1 and 1-2 are used to set the averaging function. When
averaging is enabled, a moving average of the last eight input values is output
as the converted value. The averaging function can be set separately for ana-
log inputs 1 and 2.
