Code Verifier
If the DS1500 is used as a Code Verifier, it is possible to indicate to the scanner what
code to store as the verifier code through the WinHost program, (refer to the WinHost
Help On Line).
2.3.4 Inputs
The input available on the connector supplied with the scanner is the pin relative to
the External Trigger, as indicated below:
Pin Name Function
9 EXT TRIG- external trigger -
5 GND
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
indicated in the following diagrams.
