Reading A Bar Code - Datalogic Gryphon I GPS4400 Quick Reference Manual

Reading a Bar Code

User comfort is maximized with the GPS4400 OEM module's steady,
deep red illumination light. Easier on the eyes than competitive prod-
ucts with flicker illumination, the highly visible 4-Dot aimer defines a
precise reading zone and reduces accidental reads. The aimer's cen-
ter cross provides a locator for targeted scanning in a multiple bar
code environment.
The GPS4400 omni-directional reading provides snappy decoding
performance on all common 1D and 2D codes as well as postal,
stacked and composite codes like PDF417.
For mobile marketing or ticketing applications, this imager also offers
excellent performance when reading bar codes from mobile
devices.The GPS4400 eliminates the need for separate equipment
with signature capture and document scanning capabilities.
The GPS4400 supports several modes that can be used as a trigger.
This module has the ability to automatically sense objects and trig-
ger itself. A continuous scan mode captures data whenever a bar
code passes into its field-of-view.
The reader can also be triggered remotely through software com-
mands. The GPS4400 bar code scanner supports an RS-232 serial
interface or a USB (USB-HID or USB COM) interface.
Reading a Bar Code
The Gryphon GPS4400 can be used as either a hands-free presenta-
tion scanner or a handheld. Read a bar code label by presenting the
label to the scanner, or by moving the scanner toward the target.
Center the aiming pattern and illumination system to capture and
decode the image. The aiming system will briefly switch off after the
acquisition time, and if no code is decoded will switch on again before
the next acquisition. The illumination will remain on until the symbol
is decoded.
