Fig. 6 Connection example
The selection of a volume from the memory (1 to 7) is carried out by encoding the binary
data at inputs IN1,IN2 and IN3. The following table shows the logic value at each input to
provide each of the desired seven quantities:
Volume V1
Input IN1 1
Input IN2 0
Input IN3 0
1: Input enabled (switch closed)
0: Input disabled (switch open)
Input IN4: Start / Pause function (from a push button, for example).
Output OUT: Transistor output (open collector)
