Inputs
As we explained at the beginning of the manual, the ADU device is equipped with 8 analogue and
8 digital inputs.
Analogue inputs
The analogue inputs are used for measuring sensor voltages (e.g. oil pressure sensor) or can be
used as inputs for buttons or switches. To add an analogue input, add the Analog input object in
the Project tree. The configuration pane is comprised of the following options:
Parameter Description
Name The name of the analogue input that will be used as the channel name in the
project
Pin The number of the analogue input to which the configuration relates
Type The function that the analogue input is to perform:
Switch – active low – the analogue input will function as a switch (button)
activated with a low state,
Switch – active high – the analogue input will function as a switch (button)
activated with a high state,
Rotary switch – the input assumes a value consistent with the position of
the Rotary switch. The number of the positions of the rotary switch is
defined as Min value / Max value.
Linear analog sensor – this type of input is used for measuring voltage
(you select Voltage as a Unit) or any type of linear sensors (e.g. MAP
sensor).
Calibrated analog sensor – this type of input is used for measuring the
values from sensors with a non-liner scale (e.g. temperature sensors NTC /
PTC). A 2D map is used for defining the values.
Pullup / Pulldown This function allows to activate the internal 10K resistor connected to the
ground (Pulldown) or +5V (Pullup). These resistors are activated mainly
when buttons are connected to the analogue inputs. In the case of a button
activated with a low state, you should activate Pullup 10K and the button
should connect the analogue input to ground. In the case of analogue
sensors or in the case of measuring voltage, choose the 1M Pulldown
option.
Quantity / Unit Defines the measured physical value and its unit for Linear and Calibrated
analog sensor types
Decimal places Defines the number of decimal places of the measured value for Linear and
Calibrated analog sensor types
