8.5 Input/output confi guration
k.air features free input/output mapping. For each device, sensor or contact (referred to as “points”), an acquisition channel needs
to be selected from those available on the main board or expansions.
Menu W.In/Out is used to confi gure and check the inputs and outputs connected to the k.air controller.

There are four confi guration screens:
• Wb01 - AIN (analogue inputs)
• Wb02 - DIN (digital inputs)
• Wb03 - DOUT (digital outputs)
• Wb04 - AOUT (analogue outputs).
Each of these shows a scrollable list of all the inputs/outputs available, fi ltered based on the unit confi guration, so as to assign
the reference channel and set the other fundamental parameters for processing the signal.
The following acquisition channels are available:

1 MB Main board
2 E1 Expansion 1
3 E2 Expansion 2
4 E3 Expansion 3
5 E4 Expansion 4
6 SERIAL Serial probes (max 10) and pGDx
7 KWATER Probes connected to k.water
Tab. 8.o
Note:
the channels already associated with a point cannot be reused; k.air fi lters the channels and only proposes those that
are free, depending on the type of HW selected.
Note:
universal channels (“U”) are available as AIN, DIN and AOUT.
The following parameters are available for each point:

Note:
the minimum and maximum conversion values rescale the output signal. Specifi cally, the minimum value is also active
when the unit is OFF.
8.6 Unit of measure
The k.Air controller is confi gured to display International System units of measure. Access screen Wc01 to set a diff erent unit of
measure, if desired. The options are international system (Int), Imperial (UK) and other systems used in the United States (USA)
and Canada (CAN). Below is a table showing the units of measure for each physical measurement, according to the selected
system.
