3.6 Logical inputs
DINplayer has six optoisolated logical inputs, to trigger the audio files. To activate an input,
apply a tension between 12 and 24Vdc to the Common inputs pin and the desired logical
input.
Using the binary combination of logical inputs, it is possible to activate a maximum of 63
audio files (see table 5.2).
The positive pole can be indifferently connected to the common inputs or to the logical input.
Logical input connected to ground (GND)
and external power supply:
connect Common input (pin 1) to a tension
between 12 and 24Vdc. To activate the
input connect it to power supply ground.
Logical input connected to external
power supply (12-24Vdc):
connect Common input (pin 1) to the power
supply ground. To activate the input connect
it to the power supply positive.
