complete installation of the DS2200 scanner.
1. Read all information in the section "Safety Precautions” at the beginning
of this manual.
2. Correctly position and mount the scanner for barcode reading according
to the information in par. 2.2, 2.4 and 3.4.
3. Provide correct system cabling according to the signals necessary (see
all applicable sub-paragraphs under 2.3). See also sub-paragraphs
under 2.5 for reference.
4. Install the Configuration Disk.
Upon successful completion of the installation, the readme.hlp file is
opened, giving details about how to get started configuring your scanner.
See also the Guide to Rapid Configuration link.
Specific parameter details are available in the Help On Line.
NOTE
Fine tuning of the scanner position for
barcode reading can be accomplished using
the Test Mode as described in WinHost.

SAFETY PRECAUTIONS
LASER SAFETY
The following information is provided to comply with the rules imposed by
international authorities and refers to the correct use of the DS2200 scanner.
Standard Regulations
This scanner utilizes a low-power laser diode. 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 wich allows the laser to be switched on only if the
motor is rotating above the threshold for its correct scanning speed.
The laser beam can be switched off through a software command (see
"Beam Shutter" in the WinHost Help On Line or in the "Command Strings for
DS2200" file in the DS2200 directory).
WARNING
Use of controls or adjustments or performance of
procedures other than those specified herein may result
in exposure to hazardous visible laser light.
The laser light is visible to the human eye and is emitted from the window on
the side of the scanner (Figure A, ).

The warning label indicating exposure to laser light and the device
classification is applied onto the body of the scanner (figure A, ):
CAUTION - LASER LIGHT WHEN OPEN
AVOID EXPOSURE TO BEAM
This product conforms to the applicable
requirements of 21CFR1040 at the date of
manufacture.

General Features - 1
1 GENERAL FEATURES
1.1 INTRODUCTION
The DS2200 scanner is a cost effective barcode reader complete with
decoder designed to satisfy demanding requirements associated with high
performance scanning.
The DS2200 ultra compact dimensions, based on Datalogic's experience in
miniaturised laser components, make the scanner's integration into
automated equipment extremely easy.
The DS2200 is easily configurable by means of the Windows-based user-
friendly WinHost utility program provided on diskette, or through ESC
sequences via the serial interface.
1.2 DESCRIPTION
Some of the main features of DS2200 are listed below:
•miniaturised dimensions
•scanning speed: 500 scans/sec.
•raster version available
•2 serial communication interfaces: RS232 + RS485 Half-Duplex
•reads all popular codes
•supply voltage: 5 Vdc
•test mode to verify the reading features and exact positioning of the
scanner without the need for external tools
•programmable in 4 different operating modes to suit the most various
barcode reading system requirements
•code verifier
•programmable input and output signals
•light source: solid state laser diode; 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
•low power consumption

DS2200 DATALOGIC
2- General Features
•IP65 protection class of the enclosure; the reader is therefore suitable for
industrial environments where high protection against harsh external
conditions is required.
The laser beam output window is on the side of the scanner (Figure A, 2).
A security system allows the laser to activate only once the motor has
reached the correct rotational speed; consequently, the laser beam is
generated after a slight delay from the power on of the scanner.
1.2.1 Indicators
The four LEDs on the scanner indicate the following:
POWER ON (red), indicates the reader is connected to the power supply.
(Figure A, 3).
GOOD READ (red), is used to signal the possibility of a successful barcode
reading. (Figure A, 4).
EXT TRIG (yellow), indicates external trigger activity. Refer to par. 2.3.4.
(Figure A, 5).
TX DATA (green), when blinking, indicates data transmission.
(Figure A, 6).
The screw holes on the body of the reader are for mechanical fixture
(Figure A, 8).

2.3.3 Auxiliary Interface - RS232
The auxiliary serial interface is used exclusively for RS232 point-to-point
connections. It is also used for configuring the DS2200.
The parameters relative to the auxiliary interface (baud rate, data bits, etc.)
can be defined using the Winhost utility program or "Host Mode
Programming" installed from the diskette.

The EXT TRIG input is used to connect the external trigger which tells the
scanner to scan for a code.
The active state of this input is selected in
software. Refer to the Winhost Help On Line.
The yellow LED (Figure A, 5) is on when EXT TRIG- is shorted to I/O REF.
This input was designed to be driven by an NPN type command. The
connections are indicated in the following diagram:

An anti-disturbance hardware filter is implemented on the External Trigger
input (<5 milliseconds delay).
An additional 15 ms (typical) delay can be implemented through a dedicated
software parameter (refer to WinHost Help On Line).
2.3.5 Outputs
The following pins are present on the connector of the scanner:
Pin Name Function
8 OUT1+ Output 1 +
10 I/O REF I/O Reference
11 OUT2+ Output 2 +
12 I/O REF I/O Reference
The meaning of the two outputs OUT1 and OUT2 can be defined by the user
(No Read, Right or Wrong). Refer to the Winhost Help On Line.
By default, OUT1 is associated with the No Read event, which activates
when the code signalled by the External Trigger is not decoded, and OUT2 is
associated with the Right event, which activates when the code is correctly
decoded.

2.4 POSITIONING
The DS2200 scanner is able to decode barcode labels at a variety of angles,
however significant angular distortion may degrade reading performance.
When mounting the DS2200 take into consideration these three ideal label
position angles: Pitch 0°, Skew 15° to 30° and Tilt 0°.
Follow the suggestions for the best orientation:
The Pitch angle is represented by
the value Pin Figure 2.10. Position
the reader in order to minimize the
Pitch angle.
P
Figure 2.10 - Pitch Angle
The Skew angle is represented by the
value Sin Figure 2.11. Position the
reader to assure about 15° for the
Skew angle. This avoids the direct
reflection of the laser li
g
ht emitted by
the DS2200.
For the raster version, this an
g
le
refers to the most inclined or external
raster line, so that all other raster
lines assure more than 15° Skew.
S
Figure 2.11 - Skew angle
The Tilt angle is represented by the
value Tin Figure 2.12. Position the
reader in order to minimize the Tilt
angle.

2.5 TYPICAL LAYOUTS
2.5.1 Point-to-Point
In this layout data is transmitted to the Host on the RS232 Auxiliary serial
interface.
The Local Echo communication mode must be enabled (default)
see the Winhost Help On Line.
When On-Line Operating mode is used, the scanner is activated by an
External Trigger (photoelectric sensor) when the object enters its reading
zone.

2.5.2 RS485 Master/Slave
The RS485 Master/Slave connection is used to collect data from several
scanners to build a multi-point or a multi-sided reading system; there can be
one Master and up to 5 Slaves connected together.
The Slave scanners are connected together using the RS485 half-duplex
main serial interface. Every Slave scanner must have a multidrop address in
the range 0-4.
The Master scanner is also connected to the Host on the RS232 auxiliary
serial interface.
For details, see the Guide To Rapid Configuration in the WinHost Help On
Line.
