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.
LASER SAFETY
The following information is provided to comply with the rules imposed by
international authorities and refers to the correct use of the DS8100 scanner.
Standard Regulations
This scanner utilizes up to 4 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 hazardous
visible laser light.

xi
The laser light is visible to the human eye and is emitted from the window on the side
of the scanner (Figure A, 1,Figure B, 1 and Figure C, 1).
Warning labels indicating exposure to laser light and the device classification are
applied onto the body of the scanner (Figure A, 2, 10 and 11, Figure B, 2, 3 and 4):

1 GENERAL FEATURES
1.1 INTRODUCTION
The DS8100 scanner is a barcode reader complete with decoder designed to provide
an innovative and high performance solution in omnidirectional reading applications
by combining the following advanced technologies with Datalogic’s 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.
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.

Single-Scanner and Multi-Scanner Applications
DS8100 Serial Interface version is provided with two standard interfaces allowing
easy use and connection and is therefore suitable for single-reader applications.
DS8100 Bus Interface version is particularly suited for multi-scanner applications. It is
provided with a Lonworks network for connections with other DS8100s and with an
SC8000 unit which performs real time data collection and control of the reading
station.
Flexibility
The high frequency laser diode modulation system guarantees complete immunity to
ambient light and allows installation of the DS8100 in any working area.
The DS8100 Serial Interface is easy 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 or using
the built-in keypad through the Keyboard Mode procedure.
1.2 DESCRIPTION
Some of the main features of DS8100 are listed below:
•scanning speed 1000 scans/sec. for standard models; higher speeds available
on request.
•reads all popular codes.
•supply voltage from 20 to 30 Vdc.
•test mode to verify the reading features and exact positioning of the scanner
without the need for external tools.
•programmable in 5 different operating modes to suit the most various barcode
reading system requirements.
•light source: solid state laser diodes; the light emitted has a wave length of
630~680 nm. For laser safety precautions refer to the “Safety precautions”
section at the beginning of this manual.
•2 serial communication interfaces for Serial Interface models.

1.2.1 Indicators - DS8100 Serial Interface
The DS8100 Serial Interface has six LEDs and an LCD display on the front panel.
The indicators have the following functions:
Power ON: LED (green). Indicates the scanner is ON. (Figure A, 3).
Ext Trig: LED (yellow). Indicates the external presence sensor is active. (Figure
A, 4).
Encoder: LED (yellow). Indicates the external encoder signal is active (when
provided). (Figure A, 9).
Good Read: LED (red). Indicates a code is present in the reading zone. (Figure
A, 6).
TX Data: LED (green). Indicates data transmission both on the main and on
the auxiliary interface. (Figure A, 7).
User Defined: LED (red). The use of this indicator depends on the application.
(Figure A, 8).
LCD display: The LCD displays messages relative to the DS8100 configuration
and to the code read after decoding. It is a 2 x 20 character
display. (Figure A, 5).
1.2.2 Indicators - DS8100 Bus Interface
The DS8100 Bus Interface has six LEDs on the rear panel.
The indicators have the following functions:
Power ON: LED (green). Indicates the scanner is ON. (Figure B, 10).
Ext Trig: LED (yellow). Indicates the external presence sensor is active. (Figure
B, 9).
Encoder: LED (yellow). Indicates the external encoder signal is active (when
provided). (Figure B, 8).

(Figure B, 7).
TX Data: LED (green). Indicates data transmission both on the main and on the
auxiliary interface. (Figure B, 6).
Network: LED (red). In a normal situation, this LED is OFF. If the LED blinks, check
the connections between the DS8100 and the SC8000. When this LED is
ON, the network card needs to be reprogrammed. Contact your Datalogic
distributor. (Figure B, 5).

1.3 AVAILABLE MODELS
The DS8100 scanner is available in versions that differ depending on the system of
connection, the laser number and on the laser output type:
DS8100 - X X X 0
Communication Type:
0 = Bus Interface version
1 = Serial Interface version
Laser number:
2 = Double laser
4 = Quad. laser
Laser Output Type:
0 = Standard Output Window version
1 = Oscillating Mirror version
1.3.1 Oscillating Mirror Models
Oscillating mirror models are used when coverage of a large reading area is
required, mainly in picket fence applications.
The oscillating mirror is placed in front of the reading aperture of the DS8100 scanner
to deflect the laser beam. As the mirror moves, this sweeping function of the laser
beam allows the coverage of a larger area to locate the barcodes.
The aperture angle is symmetrical and the scan line perpendicular to the scanner is
at 25° as shown in the figure below.

The oscillating function can be set to work in two different oscillating reading areas
(setpoints). The selection of which setpoint area to use is controlled by the physical
input signal PS3 (see par. 2.4.5).

par. 2.4.5).

By configuring the oscillating speed up to the maximum value of 25 Hz, raster
emulation can be performed for reading fast moving objects.
The mirror can be deflected up to 50°. For oscillating applications, the minimum
amplitude (net movement between Min and Max positions) is 6°.
These models provide higher scanning speed (1200 scans/s) compared to standard
models and the reading performance is not adversely effected by the oscillating
mirror.
The oscillating mirror is completely controlled by software commands and therefore
avoids complex mechanical calibrations. For details of the software configuration
parameters see the WinHost Help On Line.
