CBX ELECTRICAL CONNECTIONS

4.5 INPUTS

There are two optocoupled polarity insensitive inputs available on the scanner: Input 1
(External Trigger) and Input 2, a generic input:
The electrical features of both inputs are:

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.

This input is optocoupled and can be driven by both an NPN and PNP type command. The
connections are indicated in the following diagrams:
