Datalogic Scanning DX6400 - Manual (Page 19)

COMMON FEATURES

Mount the scanner using the ST-237 mounting bracket which assures an angle of 16°, as indicated in the figure
below, in order to obtain an angle of 90° between the two scan lines. This guarantees an omni directional reading
of the barcode, if the code label satisfies the ACR™ 4 conditions (see Scanner Reference Manual for details).
DX6400 Mounting Position
WARNING
When installing several scanners, take care to position them correctly so that no laser beam
enters the reading window perpendicularly and at the same level of the output beam of the
other scanners. This condition could occur more frequently for side mounted applications. If
these precautions are not followed, it may occur that the laser of the blinded scanner starts
blinking due to an internal circuit which temporarily turns the laser off when detecting a power
anomaly. To resolve this problem, it is sufficient to slightly change the inclination and position
of one of the two scanners involved.
FLASH™ Dynamic Focus:
The DX6400 has an innovative linear motor designed to control the focus position of the scanner via software.
This dynamic system, called FLASH™, is able to move the focus position rail to rail, from the minimum position to
the maximum position.
The FLASH™ functionalities (i.e. the driving modes of the linear motor) are programmed via the Genius™
software tool and can operate in the following modes:
- Fixed mode: the focus is set to the desired position via software (expressed in cm);
- Continuous mode: the focus position is continuously running from a minimum position to a maximum position
with a defined frequency;
- Triggered mode: the focus position can be set depending on the received external input (photocell, barrier,
serial message, etc.);
- D-Flash™ mode: the focus position can be set depending on the measured distance between the scanner
and the scanned object. This is the most innovative and flexible function that makes different software
implementations possible. The D-Flash™ development has been based on the minimum distance detected.
Thus, it can apply to the
widest variety of applications. Further developments of D-Flash™ will be provided
according to the specific application needs.
