DS1500

 

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).

2.3.4Inputs

The input available on the connector supplied with the scanner is the pin relative to the External Trigger, as indicated below:

EXT TRIG-

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.
