SAFETY PRECAUTIONS
ELECTRICAL SAFETY
This product conforms to the applicable requirements contained in the European
Standard for electrical safety EN-60950 at the date of manufacture.
This symbol refers to operations that must be performed by qualified personnel
only. Example: opening the device.
This symbol refers to operations where there is danger of electrical shock. Before
opening the device make sure the power cable is disconnected to avoid electric
shock.
For AC models, this device must be installed to a power source equipped with
on/off switch or breaker within range of the operator as protection against
grounding failures.
This device is protected against overloading by correct value fuses. For
protection fuse replacement make sure correct value fuses are installed. See the
fuse selection table in par. 5.2.
LASER SAFETY
The following information is provided to comply with the rules imposed by international
authorities and refers to the correct use of the DX8200 scanner.
Standard Regulations
This scanner utilizes up to 3 low-power laser diodes. Although staring directly at the laser
beam momentarily causes no known biological damage, avoid staring at the beam as one
would with any very strong light source, such as the sun. Avoid that the laser beam hits the
eye of an observer, even through reflective surfaces such as mirrors, etc.
This product conforms to the applicable requirements of both IEC 825-1 and CDRH 21 CFR
1040 at the date of manufacture. The scanner is classified as a Class 2 laser product
according to IEC 825-1 regulations and as a Class II laser product according to CDRH
regulations.
There is a safety device which allows the laser to be switched on only if the motor is rotating
above the threshold for its correct scanning speed.
WARNING
Use of controls or adjustments or performance of procedures other than
those specified herein may result in exposure to dangerous laser
radiation.

x
The laser light is visible to the human eye and is emitted from the windows on the lower side
of the reader (Figure A, 3).
Warning labels indicating exposure to laser light and the device classification are applied
onto the body of the scanner (Figure A, 5 and 2):
Warning and device class labels
Disconnect the power supply when opening the device during maintenance or installation to
avoid exposure to hazardous laser light.
The laser diodes used in this device are classified as Class 3B laser products according to
IEC 825-1 regulations and as Class IIIb laser products according to CDRH regulations. As it is
not possible to apply a classification label on the laser diodes used in this device, the
following label is reproduced here:
Laser diode class label
Any violation of the optic parts in particular can cause radiation up to the maximum level of
the laser diode (35 mW at 630~680 nm).

1 GENERAL FEATURES
1.1 INTRODUCTION
The DX8200 scanner is a high performance omnidirectional barcode reader providing a plug
and play approach towards omnidirectional system reading applications by combining the
following advanced technologies with Datalogic solid experience in the material handling
sector.
ACR™
Advanced Code Reconstruction technology allows the reading of low aspect ratio labels
placed anywhere on a parcel and enhances the readability of poorly printed or damaged
codes.
CD SQUARE™
CD SQUARE™ provides useful information on label position and object shape elaborated
during the barcode reading phase. This innovative technology identifies the area in which the
code is located and measures the code distance from the scanner.
PACKTRACK™
PackTrack™ is a Datalogic patented parcel tracking system which improves the reading
features in omnidirectional stations. In particular, PackTrack™ manages 6-sided reading
systems when it is impossible to detect the real position of the code on the parcel, thus
overcoming the need for external accessories essential in traditional tracking systems. See
par. 4.2 for more details.
ASTRA™
Automatically Switched Reading Area™ is the new Datalogic technology based on a multi-
laser architecture and a fixed mounted optic system which concentrates the multiple laser
emissions in a single laser beam. As each laser emitter is focused on a specific range of the
reading area, a sophisticated electronic controller selects the best focused laser emitter with
respect to the code to read. This allows the reading of medium-high density codes in a large
reading area on very fast conveyors.

Flexibility
The high frequency laser diode modulation system guarantees complete immunity to ambient
light and allows installation of the DX8200 in any working area.
The DX8200 Serial Interface models are easily configurable by means of the Windows-based
user-friendly WinHost utility program provided on diskette.
It can also be configured from a Host PC through the Host Mode procedure.
