3.3.5 Inputs
The inputs available on the connector supplied with the scanner are the pins relative to the
External Trigger and generic input, as indicated below:
Pin Name Function
18 EXT TRIG A External Trigger A (polarity insensitive)
19 EXT TRIG B External Trigger B (polarity insensitive)
10 IN2- Input 2 -
25 GND Power Ground/IN2 Reference
The External Trigger input is used in the On-Line operating Mode and tells the scanner to
scan for a code. The active state of this input is selected in software. Refer to the Genius™
Help On Line.
The yellow Trigger LED (
Figure A, 6) is on when the External Trigger forces a current flow
through the EXT TRIGA and EXT TRIGB pins.
This input is optocoupled and can be driven by both an NPN and PNP type command. The
connections are indicated in the following diagrams:
