Auxiliary Interface; Inputs - Datalogic DS6300 Reference Manual

INSTALLATION

Auxiliary Interface

The auxiliary serial interface is equipped with RS232 full-duplex interface connections. The
interface type is exclusive and is selectable through the Genius™ configuration program.
The following pins of the 25-pin and 26-pin connector are used for RS232 full-duplex
interface connection:

Inputs

The inputs of the reader are on the 25-pin and 26-pin connector (Figure 4, 1 and Figure 5, 1)
of the DS6300.
These inputs are called EXT_TRIG, IN2, IN3 and IN4.
Pin Name
18 EXT_TRIG A External trigger (polarity insensitive)
19 EXT_TRIG B External trigger (polarity insensitive)
6 IN2A
10 IN2B
14 IN3A
15 IN4A
24 IN_REF
IN2 is normally used for the Encoder input. In PackTrack™ mode, it detects the conveyor
speed.
EXT_TRIG is the main presence sensor. When active, this input tells the scanner to scan for
a code and that decoding can take place. The yellow LED (Figure 3,3) indicates the
EXT_TRIG is active.
IN3 and IN4 can be used as the stop signal for the reading phase.
All inputs are optocoupled, polarity insensitive, and driven by a constant current generator;
the command signal is filtered through an anti-disturbance circuit which generates a delay
which can be set to 5 ms or 500 µs. In particular, EXT_TRIG, IN3 and IN4 share the same
value which usually corresponds to 5 ms when using a photoelectric sensor, while IN2 has a
different value which is set to 500 µs when this input is used for the Encoder.
