Digital Inputs - Datalogic STS320 Series Installation Manual

DIGITAL INPUTS

There are two optocoupled polarity insensitive inputs available on the reader: Input 1
(External Trigger) and Input 2, a generic input:
These inputs can be used to control (start/stop) the reading phase:

PLC Digital Output
NOTE
The electrical features of both inputs are:
The active state of these inputs is selected in software.
An anti-disturbance filter is implemented in software on both inputs so that the mini-
mum pulse duration is ≅ 0.5 milliseconds. This value can be increased through software.
These inputs are optocoupled and can be driven by PNP type commands.
