5.5 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:

Maximum voltage: 30 Vdc

Maximum current: 12 mA

An anti-disturbance filter is implemented in software on both inputs so that the minimum pulse duration is

 5 milliseconds. This value can be increased through the software parameter Debounce Filter, see the "2K/4K Family Software Configuration Parameter Guide”

Help file".

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

, 3) is on when the active state of the External Trigger corresponds to ON.

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