Wiring switching inputs
If the bar code scanner's reading process should be triggered by an external sensor, the rea-
ding pulse sensor is connected to the "
Sensor 1
" switching input.
Fig. 6-6:
Wiring the “Sensor 1“ switching input on the 15-pole D-Sub-HD plug
The "
Sensor 2
" switching input has the following functions, among others:
Trigger source for
•
Incremental encoder input
•
Reading pulse generator for reading pulse end

Important
The ratings for "Sensor 1" and "Sensor 2" are identical.
Tab. 6-7:
Ratings for the switching inputs
Connect switching inputs depending on application.
Switching behaviour
Power fed to the input opens the internal reading gate of the bar code
scanner.
(Default setting: active high; debouncing: max. 30 ms (standard))
Features
– Optodecoupled, reverse polarity protected
– Can be wired with the PNP output of a sensor
