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 DS2100 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 which 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 also the
WinHost Help On Line).
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 front
of the scanner (Figure A, 8).

INTRODUCTION
The DS2100 laser scanner satisfies the most advanced needs of a wide range of
users. It has been developed focusing on the realistic requirements of its target
market. The outstanding result is an extremely compact, cost-effective and easy to
use industrial scanner.
C-Programmability
The DS2100 belongs to the generation of Datalogic scanners
that operate under the 'C' programming environment, which
is a recognized industry standard.
Standard Application
Program
A standard application program is factory-loaded onto the
DS2100. This program controls barcode reading, serial port
interfacing, data formatting and many other operating and
control parameters.
It is completely configurable from a host computer through
the WinHost utility program provided on diskette with the
scanner, or through ESC sequences via the serial interface.

Main Serial Interface
The signals relative to the following serial interface types are available on the
input/output connector of DS2100 depending on the DS2100 model (see par. 1.3).
A passive 20-mA Current Loop interface is available if the optional INT-22 accessory
is installed. This accessory interface replaces the main serial interface of the DS2100
model. The INT-22 accessory board is not available for DS2100-X3X0 models.
If the interface type is not compatible with the current communication handshaking,
then the system forces the handshake to none.
The parameters relative to the interface selected (baud rate, data bits, etc.) can
be defined using the WinHost utility program or "Host Mode" programming
procedure through ESC sequences installed from the diskette.
Details regarding the connections and use of the interfaces are given in the next
paragraphs.

When the auxiliary interface is permanently connected as part of the system cabling,
it is recommended to connect the cable shield to earth ground.
The RTSAUX and CTSAUX signals control data transmission and synchronize the
connected devices. If the RTS/CTS handshaking protocol is enabled, the DS2100
activates the RTSAUX output to indicate a message is to be transmitted. The
receiving unit activates the CTSAUX input to enable the transmission.

Code Verifier
If the DS2100 is used as a Code Verifier, it is possible to indicate to the scanner what
code to store as the verifier code by means of an external hardware input.
The Code Verifier parameter must be enabled and the configuration parameters to
allow correct Code Type reading must be saved to the scanner in order to read the
verifier code.
To activate the input, connect together pins 23 and 24 (CTSAUX and RTSAUX) of
the 25-pin connector (for example with a push-button), before the active edge of the
External Trigger input (or before the code passes under the laser beam for the
Automatic operating mode). The next read code will be stored as the verifier code in
the scanner's RAM and NON-VOLATILE (EEPROM) memory by default. Then, the
two pins must be disconnected.
Since it uses part of the RS232 auxiliary serial interface, this interface is limited when
using this option and the Handshake selection must not be set to RTS/CTS.

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 signaled by the external trigger is not decoded, and OUT2 is associated with
the Right event, which activates when the code is correctly decoded.

POSITIONING
The DS2100 scanner is able to decode barcode labels at a variety of angles,
however significant angular distortion may degrade reading performance.
When mounting the DS2100 take into consideration these three ideal label position
angles: Pitch 0°, Skew 10° to 30° and Tilt 0°.
Follow the suggestions for the best orientation:
The Pitch angle is represented by the value P in Figure 19. Position the reader in
order to minimize the Pitch angle.
P
Figure 19 - Pitch Angle
The Skew angle is represented by the value S in Figure 20. Position the reader to
assure at least 10° for the Skew angle. This avoids the direct reflection of the laser
light emitted by the DS2100.
For the raster version, this angle refers to the most inclined or external raster line, so
that all other raster lines assure more than 10° Skew.
S

The Tilt angle is represented by the value T in Figure 21. Position the reader in order
to minimize the Tilt angle.

TYPICAL LAYOUTS
The following typical layouts refer to system hardware configurations. Dotted lines in
the figures refer to optional hardware configurations within the particular layout.
These layouts also require the correct setup of the software configuration
parameters. Complete software configuration procedures can be found in the Guide
To Rapid Configuration in the WinHost Help On Line.

Point-to-Point
In this layout the data is transmitted to the Host on the main serial interface. Host
Mode programming can be accomplished either through the main interface or the
Auxiliary interface.
In Local Echo communication mode, data is transmitted on the RS232 auxiliary
interface independently from the main interface selection.
When On-Line Operating mode is used, the scanner is activated by an External
Trigger (photoelectric sensor) when the object enters its reading zone.

Pass-Through
Pass-through mode allows two or more devices to be connected to a single external
serial interface.
Each DS2100 transmits the messages received by the Auxiliary interface onto the
Main interface. All messages will be passed through this chain to the host.
When On-Line Operating mode is used, the scanner is activated by an External
Trigger (photoelectric sensor) when the object enters its reading zone.

RS232 Master/Slave
The RS232 master/slave connection is used to collect data from several scanners to
build either a multi-point or a multi-sided reading system; there can be one master and
up to 9 slaves connected together.
The Slave scanners use RS232 only on the main and auxiliary serial interfaces. Each
slave DS2100 transmits the messages received by the auxiliary interface onto the main
interface. All messages will be passed through this chain to the Master.
The Master scanner is connected to the Host on the main serial interface. The possible
main interface types for the master scanner are RS232 or RS485.
There is a single reading phase and a single message from the master scanner to the
Host computer.
Either On-Line or Serial On-Line Operating modes can be used in this layout.
When On-Line Operating mode is used, the external trigger signal is unique to
the system, however it is not necessary to bring the external trigger signal to the
Slave scanners.
The main and auxiliary ports are connected as shown in the figure below.

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 RS485 half-duplex on the 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.
The External Trigger signal is unique to the system; there is a single reading phase
and a single message from the master scanner to the Host computer.
It is necessary to bring the External Trigger signal to all the scanners.
The main and auxiliary ports are connected as shown in the figure below.

READING FEATURES
The number of scans performed on the code by the DS2100 and therefore the
decoding capability is influenced by the following parameters:
•
•
•
•
number of scans per second
code motion speed
label dimensions
scan direction with respect to code motion
At least 5 scans during the code passage should be allowed to ensure a successful
read.
3.1
STEP-LADDER MODE
If scanning is perpendicular to the code motion direction (Figure 27), the number of
effective scans performed by the reader is given by the following formula:
SN = [(LH/LS) * SS] – 2
Where:
SN = number of effective scans
LH
LS
SS
= label height (in mm)
= label movement speed
in (mm/s)
= number of scans per second
Direction of code
movement at LS speed

READING FEATURES

For example, the DS2100 (350 scans/sec.) for a 25 mm high code moving at 500
mm/s performs:
[(25/500) * 350] - 2 = 15 effective scans.
3.2
PICKET-FENCE MODE
If scanning is parallel to the code motion, (Figure 28), the number of effective scans
is given by the following formula:
SN = [((FW-LW)/LS) * SS] -2
Where: SN = number of effective scans
FW = reading field width (in mm)
LW = label width (in mm)
LS = label movement speed
(in mm/s)
SS = scans per second
Direction of code
movement at LS speed

Figure 28 - "Picket-Fence" scanning mode
For example, for a 50 mm wide code moving in a point where the reading field is 200
mm wide at a 1500 mm/s speed, the DS2100 (350 scans per sec.), performs:
[((200-50)/1500) * 350] - 2 = 33 scans
