The input available on the connector supplied with the scanner is the pin relative to
the External Trigger, as indicated below:
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 WinHost Help On Line.
The yellow LED (Figure A, 5) is on when the External Trigger forces a current flow
through the EXT TRIG- and GND pins.
This input is designed to be driven by an NPN type command. The connections are
