Connect 4 analogue inputs to AI1, AI2, AI3 and AI4.
With the parameter S you can then choose between the 4 inputs for what is output at AQ:
|S = 0||AQ = 0||0 is selected|
|S = 1||AQ = AI1||Analogue input 1 is selected|
|S = 2||AQ = AI2||Analogue input 2 is selected|
|S = 3||AQ = AI3||Analogue input 3 is selected|
|S = 4||AQ = AI4||Analogue input 4 is selected|
If the input DisP is enabled AQ = 0, or S is a value that is not in the range 0-4 then AQ = 0.
