STEP 3 – FOCUS THE SCANNER
The reading distance depends on the focus distance of the scanner and should be set according to the application requirements. The Focus Position is set directly through the focus adjustment screw on the front panel of the scanner. This screw moves the internal lens of the scanner to change the focal length of the scanner. The setting is continuous but should not be set beyond the limits "Too Far" or "Too Near" which appear on the display at the extremes of the focus range. Although the scanner reads across the entire focus range, there
are three guaranteed positions which correspond to the reading diagrams in par. 7.4.
1. Power up the scanner
. For Subzero models, At -35 °C, a 20-minute
warm-up period is required before the scanner is ready to read barcodes, the Ready LED blinks.
Wait for the power up sequence to finish. By default the scanner focus is in the Unlocked position. The alternating message on the display shows the mechanical Focus Position.
2. Using a screwdriver turn the focus adjustment screw in the desired direction, clockwise (focus nearer to the scanner) or counterclockwise (focus farther from the scanner). The focus position in centimeters and inches is shown on the scanner display.
NOTE
The value of the Focus Position must be stored in memory. If the mechanical position changes by more than the allowed tolerance of the value in memory, an alarm will be sent. See the Focus Lock function in step 4,
X-PRESS™ Configuration.

STEP 4 – X-PRESS™ CONFIGURATION
X-PRESS™ is the intuitive Human Machine Interface designed to improve ease of installation and maintenance.
Status and diagnostic information are clearly presented by means of the five colored LEDs, whereas the single push button gives immediate access to the following relevant functions:
AutoSetup to self-optimize and auto-configure reading performance in demanding applications
AutoLearn to self-detect and auto-configure for reading unknown barcodes (by type and length)
Focus Lock to memorize the mechanical focus position
Test Mode with bar graph visualization to check static reading performance
The colors and meaning of the five LEDs are illustrated in the following table:
TRIGGER Yellow This LED indicates the status of the reading phase. *
STATUS Red This LED indicates a NO READ result.
* In On-Line mode the TRIGGER LED corresponds to the active reading phase signaled by the Presence Sensor.
In Automatic and Continuous modes the TRIGGER LED is always on indicating that the reader is ready to read a code.
** When connected to a Fieldbus network through the CBX500, the COM LED is always active, even in the absence of data transmission, because of polling activity on the Fieldbus network.
During the reader startup (reset or restart phase), all the LEDs blink for one second.
On the back of the reader near the cable, the “POWER ON” LED indicates the laser scanner is correctly powered.
NOTE
When entering the X-PRESS™ interface on the DS4800-X1XX the Oscillating

2. From the Genius™ Device Menu select “Local Device Network Settings” and program the
Role of the Master scanner (Synchronized or Multidata).
This procedure requires the Network Baud Rate be the same for all Slaves and Master,
(500 kbs is the default value). It can be changed after network setup using Genius™ through the Master scanner. See also the alternative procedure in the note below.
3. At the prompt to "Send updated Network configuration to the Local Device" (Master) choose "Yes".
4. Then run the NET-AUTOSET procedure from the Icon in the Devices Area. Genius™ sets all slave scanners according to the Master Role (Synchronized or Multidata), and assigns each a random address. If necessary, this address can be changed through the
Network Wizard.
5. Configure the System parameters via Genius™.
6. If using the CBX connection box equipped with a BM100 Backup module, perform
System Backup at the Master.
The scanner network is ready.
NOTE
If necessary, the ID-NET™ baudrate can be set individually on each Slave scanner to match the Master. Connect each Slave to Genius™ and set the
Reading System Layout > Network Baudrate parameter. Then follow the procedure above.
NOTE
An alternative method of programming scanner address and role assignment can be accomplished by using the “Connectivity Programming Barcodes”
(refer to the “ID-NET™ Setup Procedure Using Programming Barcodes” document on the product CD).

2.3 X-PRESS™ HUMAN MACHINE INTERFACE
X-PRESS™ is the intuitive Human Machine Interface designed with the precise goal of improving ease of installation and maintenance.
Status and diagnostic information are clearly presented by means of five-colored LEDs, whereas the single multi-function key gives immediate access to relevant functions:
Autosetup to self-optimize reading performance in demanding applications
Autolearn to self-detect unknown barcodes
Focus Lock to memorize the mechanical focus position
Test Mode with bar-graph visualization to check static reading performance
X-PRESS™ is the common interface adopted in all new products: “You learn one, you can
use them all”.
The colors and meaning of the five LEDs when in the one of the operating modes (On-Line,
Automatic or Continuous) are illustrated in par 2.1.1.
NOTE
Except for the Focus Lock/Unlock function, the X-PRESS™ functions do not
work if the motor or laser are turned off, see chp. 9 for details.
2.3.1 Diagnostic Indication
The “STATUS” and “READY” LEDs blink simultaneously to signal the presence of a failure.
Diagnostic message can be enabled to provide details about specific failure conditions.
These messages will be shown on the display and if enabled for transmission, also on the selected interfaces.
At the same time one or more LEDs light up according to the following scheme:

AutoLearn Function
Once entered, the reader starts a procedure to automatically detect and recognize barcodes
(by type and length), which are presented to it
. The laser turns on and the LEARN LED blinks to indicate the ongoing process.
The procedure is as follows:
- place the desired barcode on the scanline.
- wait until the LEARN LED stays steady on (indicating the reader has detected the barcode).
- repeat, if needed, the above two steps to program up to 10 different barcodes (the LEARN
LED returns to the blinking state for the next code). If more than one barcode is detected in the scan line, the Multi Label mode is enabled (refer to the “2K/4K Family Software
Configuration Parameter Guide” Help file).
- exit the process by pressing the X-PRESS™ push button once.
The scanner will restart at the end of the process, and then the detected barcodes are automatically configured in scanner memory.
AutoSetup Function
Once entered, if a barcode label is positioned in front of the scanline, the scanner automatically performs the optimal setup of the reading parameters for that specific barcode.
The procedure is as follows:
-
-
place the desired barcode on the scanline.
enter the AutoSetup function (the laser turns on and the SETUP LED blinks to indicate the ongoing process).
-
wait until the SETUP LED stays steady on (indicating the reader has detected the barcode).
This procedure ends either when the barcode is successfully decoded or after a timeout of about 7 (seven) seconds.
The scanner will restart at the end of the process, and then the optimized reading parameters for that barcode are automatically configured in scanner memory.
NOTE
The AutoSetup function does not modify the programmed barcode symbologies. If needed, the AutoLearn function can be performed after
Autosetup.

Focus Lock/Unlock
Once entered, the scanner automatically performs the Focus Lock procedure to save the mechanical focus position to memory. If the mechanical focus position is changed by more than the allowed tolerance of the value in memory, a diagnostic alarm will be sent to the display.
The procedure is as follows:
-
enter the Focus Lock function.
-
wait until the "Focus locked at..." message appears on the display (indicating the focus position has been saved to memory). The following parameters are set:
Locked Position = your mechanical setting
Focus Displacement (Alarm) = set (default to display only)
If the Focus lock has already been set, this procedure can be used to Unlock the focus value.
In this case control of the focus position is disabled.
The scanner will restart at the end of the process.
Reset Scanner to Factory Default
If it ever becomes necessary to reset the scanner to the factory default values, you can perform this procedure by holding the X-PRESS™ push button pressed while powering up the scanner. At the end of the procedure (about 5-6 seconds), the Configuration and
Environmental parameters are reset, all LEDs blink simultaneously 3 times and the message
"Default Set" is shown on the display.
2.4 DISPLAY

2.5 OSCILLATING MIRROR MODELS
The DS4800 OM is completely software controlled and software programmable through
Genius™ which allows adjusting the oscillating frequency and the minimum and maximum oscillation angles of two separate reading zones.
When the oscillating mirror is programmed to read barcode labels at small angles, position the reader to assure at least 15° for the Skew angle. This angle refers to the most inclined or external laser line, so that all other laser lines assure more than 15° Skew. This avoids the direct reflection of the laser light emitted by the reader.
35°
15°
0°
-5° code surface
Figure 5 – Oscillating Mirror Skew Angle
Otherwise, the scanner can be mounted at an angle of inclination of 15° in order to attain symmetrical deflection ranges.

Figure 6 - Oscillating Mirror Reading Position
In the above case, the zone where the scan line is perpendicular to the reflecting surface corresponds to a neutral zone at the center of the reading field.
NOTE
By limiting the raster width to the minimum necessary, the number of scans on the reading surface is increased.

2.6 SUBZERO TEMPERATURE MODELS
The DS4800 Subzero scanner is an industrial scanner designed to operate in industrial refrigerator/freezer cells or other stable subzero degree environments, which are below the operating range of standard industrial scanners. It is not designed to move between subzero and normal environments (rapid temperature changes).
It has a patent-pending intelligent microprocessor-driven and very efficient internal heating system which constantly monitors and automatically controls internal temperature, heating only the necessary temperature-sensitive components and thereby keeping them functioning within their designed operating range even though the outside temperature is below this value. This results in very low overall power consumption. Part of this system also heats the
Laser Beam Output window to eliminate ice and/or condensation build-up from negatively affecting the reading results.
Upon power-up in a subzero environment, the scanner waits until these internal components are heated to within their operating temperature range. For example, power-up at -35 °C can take about 20 minutes before the scanner is ready to read barcodes. During this time the laser, motor, and display remain off and the Ready LED blinks, indicating the warm-up phase. Scanner communication is however operative and it can be configured through
Genius™ or through Host Mode Programming during this phase.

3.3 POSITIONING
The DS4800 scanner is able to decode moving barcode labels at a variety of angles, however significant angular distortion may degrade reading performance.
When mounting the DS4800 take into consideration these three ideal label position angles:
Skew 15° to 30°, Tilt 0° and Pitch 0°.
Follow the suggestions for the best orientation:
The Skew angle is represented by the value S in Figure 19. Position the reader to assure at
least 15° for the Skew angle. This avoids the direct reflection of the laser light emitted by the
DS4800.
S
S
Figure 19 – DS4800 Skew Angle
The Tilt angle is represented by the value T in Figure 20. Position the reader in order to
minimize the Tilt angle.

4.3.1 ID-NET™ Cables
The following instructions are referred to Figure 30, Figure 31 and Figure 32.
The general cable type specifications are: CAT5 twisted pair + additional CAT5 twisted pair, shielded cable AWG 24 (or AWG 22) stranded flexible.
We recommend using DeviceNet cables (drop or trunk type) to the following reference standards:
AN50325 – IEC 62026
UL STYLE 2502 80°C 30V
Cable Shield MUST be connected to earth ground ONLY at the Master.
NEVER use ID-NET™ cable shield as common reference.
The ID-NET™ max cable length depends on the baudrate used, (see the Baudrate Table below).
For Common Power Connections use only 2 wires (ID+ and ID-).
-
-
-
DC Voltage Power cable (Vdc – GND) should be handled as a signal cable (i.e. do not put it together with AC cable):
Wire dimensioning must be checked in order to avoid voltage drops greater than 0.8
Volts.
Cable should lie down as near as possible to the ID-NET™ cable (avoiding wide loops between them).
Scanner's chassis may be connected to earth.

6 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 Genius™ Help On Line.
6.1 POINT-TO-POINT
In this layout the data is transmitted to the Host on the main serial interface. A Genius™ based 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.

In this layout a single scanner functions as a Slave node on a Fieldbus network. The data is transmitted to the Host through an accessory Fieldbus interface board installed inside the
CBX500 connection box.
Scanner configuration can be accomplished through the Auxiliary interface using the
Genius™ configuration program or Genius™ based Host Mode programming.
In Local Echo communication mode, data is transmitted on the RS232 auxiliary interface independently from the Fieldbus interface selection.
When On-Line Operating mode is used, the scanner is activated by an External Trigger

6.2 PASS-THROUGH
Pass-through mode allows two or more devices to be connected to a single external serial interface.
Each DS4800 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.
Applications can be implemented to connect a device such as a hand-held reader to the
Auxiliary port of the last scanner in the chain for manual code reading capability.

An alternative Pass-Through layout allows the more efficient ID-NET™ network to be used.
This layout is really an ID-NET Master/Slave Multidata layout which also allows each scanner (Master and Slaves) to accept input on the Auxiliary interface, for example to connect a device such as a hand-held reader for manual code reading capability.
Each DS4800 transmits its own messages plus any messages received by its Auxiliary interface onto the ID-NET™ interface. The Master passes all messages 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.

6.3 ID-NET™
The ID-NET™ 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 31 slaves connected together.
The slave scanners are connected together using the ID-NET™ interface. Every slave scanner must have an ID-NET™ address in the range 1-31.
The master scanner is also connected to the Host on the RS232/RS485 main serial interface.
For a Master/Slave Synchronized layout 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 not necessary to bring the External Trigger signal to all the scanners.
The main, auxiliary, and ID-NET™ interfaces are connected as shown in the figure below.

6.4 RS232 MASTER/SLAVE
NOTE
This interface is provided for backward compatibility. We recommend using the more efficient ID-NET™ network for Master/Slave or Multiplexer layouts.
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
DS4800 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 RS232/RS485 main serial interface.
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.

7 READING FEATURES
7.1 ADVANCED CODE RECONSTRUCTION (ACR™ 4)
The traditional way of barcode reading could be called “Linear Reading”. In this case, the laser beam crosses the barcode symbol from its beginning to its end as shown in the following figure:
Laser Beam
Figure 79 – Linear Reading
In Advanced Code Reconstruction mode it is no longer necessary for the laser beam to cross the label from the start to the end. With just a set of partial scans on the label (obtained using the motion of the label itself), the scanner is able to “reconstruct” the barcode. A typical set of partial scans is shown in the figure below:
Code Direction
Figure 80 – Partial Scans
None of the partial scans contains the whole label. The decoder aligns each partial scan correctly and combines them in order to obtain the entire code.
The alignment is performed by calculating the time difference from one partial scan to another using a reference code element.
ACR4 therefore has an intrinsic ability to increase the reading percentage of damaged codes as in the examples below:

7.2 LINEAR CODE READING
The number of scans performed on the code by the DS4800 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.
7.2.1 Step-Ladder Mode
If scanning is perpendicular to the code motion direction (Figure 84), 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 = label height (in mm)
LS = label movement speed in (mm/s)
SS = number of scans per second
Direction of code movement at LS speed
DS4800
LH
Laser beam
Figure 84 - "Step-Ladder" Scanning Mode
For example, the DS4800 (800 scans/sec.) for a 25 mm high code moving at 1250 mm/s performs:
[(25/1250) * 800] - 2 = 14 effective scans.
89
DS4800 REFERENCE MANUAL
7
7.2.2 Picket-Fence Mode
If scanning is parallel to the code motion, (Figure 85), 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
Direction of code m at LS speed ovement

For example, for a 60 mm wide code moving in a point where the reading field is 160 mm wide at a 2000 mm/s speed, the DS4800 (800 scans per sec.), performs:
[((160-60)/2000) * 800] - 2 = 38 effective scans

GLOSSARY
ACR4™ (Advanced Code Reconstruction)
This is a powerful code reconstruction technology (ACR™ 4). The new fourth generation
ACR™ considerably increases the code reconstruction reading capability in the case of damaged or very tilted barcodes.
Aperture
Term used on the required CDRH warning labels to describe the laser exit window.
Barcode
A pattern of variable-width bars and spaces which represents numeric or alphanumeric data in machine-readable form. The general format of a barcode symbol consists of a leading margin, start character, data or message character, check character (if any), stop character, and trailing margin. Within this framework, each recognizable symbology uses its own unique format.
Barcode Label
A label that carries a barcode and can be affixed to an article.
Baud Rate
A unit used to measure communications speed or data transfer rate.
CDRH (Center for Devices and Radiological Health)
This organization (a service of the Food and Drug Administration) is responsible for the safety regulations governing acceptable limitations on electronic radiation from laser devices.
Datalogic devices are in compliance with the CDRH regulations.
Code Positioning
Variation in code placement that affects the ability of a scanner to read a code. The terms
Pitch, Skew, and Tilt deal with the angular variations of code positioning in the X, Y and Z
axes. See pars. 3.2.1 and 3.3. Variations in code placement affect the pulse width and
therefore the decoding of the code. Pulse width is defined as a change from the leading edge of a bar or space to the trailing edge of a bar or space over time. Pulse width is also referred to as a transition. Tilt, pitch, and skew impact the pulse width of the code.
Decode
The process of translating a barcode into data characters using a specific set of rules for each symbology.
Decoder
As part of a barcode reading system, the electronic package which receives the signals from the scanner, performs the algorithm to interpret the signals into meaningful data and provides the interface to other devices. The decoder is normally integrated into the scanner.
EAN
European Article Number System. The international standard barcode for retail food packages.
FLASH
An on-board non-volatile memory chip.
107
Full Duplex
Simultaneous, two-way, independent transmission in both directions.
Half Duplex
Transmission in either direction, but not simultaneously.
Host
A computer that serves other terminals in a network, providing services such as network control, database access, special programs, supervisory programs, or programming languages.
Interface
A shared boundary defined by common physical interconnection characteristics, signal characteristics and meanings of interchanged signals.
LED (Light Emitting Diode)
A low power electronic device that can serve as a visible or near infrared light source when voltage is applied continuously or in pulses. It is commonly used as an indicator light and uses less power than an incandescent light bulb but more than a Liquid Crystal Display
(LCD). LEDs have extremely long lifetimes when properly operated.
Multidrop Line
A single communications circuit that interconnects many stations, each of which contains terminal devices. See RS485.
Parameter
A value that you specify to a program. Typically parameters are set to configure a device to have particular operating characteristics.
Picket-Fence Orientation
When the barcode’s bars are positioned vertically on the product, causing them to appear as
a picket fence. The first bar will enter the scan window first. See par. 7.2.2.
Pitch
Rotation of a code pattern about the X-axis. The normal distance between center line or
adjacent characters. See pars. 3.2.1 and 3.3.
Position
The position of a scanner or light source in relation to the target of a receiving element.
Protocol
A formal set of conventions governing the formatting and relative timing of message exchange between two communicating systems.
Raster
The process of projecting the laser beam at varied angles spaced evenly from each other.
Typically, the mirrored rotor surfaces are angled to create multiple scan lines instead of a single beam.
Resolution
The narrowest element dimension, which can be distinguished by a particular reading device or printed with a particular device or method.
108
RS232
Interface between data terminal equipment and data communication equipment employing serial binary data interchange.
RS485
Interface that specifies the electrical characteristics of generators and receivers for use in balanced digital multipoint systems such as on a Multidrop line.
Scanner
A device that examines a printed pattern (barcode) and either passes the uninterpreted data to a decoder or decodes the data and passes it onto the Host system.
Serial Port
An I/O port used to connect a scanner to your computer, identifiable by a 9-pin or 25-pin connector.
Signal
An impulse or fluctuating electrical quantity (i.e.: a voltage or current) the variations of which represent changes in information.
Skew
Rotation about the Y-axis. Rotational deviation from correct horizontal and vertical
orientation; may apply to single character, line or entire encoded item. See pars. 3.2.1 and
Step-Ladder Orientation
When the barcode’s bars are positioned horizontally on the product, causing them to appear
as a ladder. The ends of all bars will enter the scan window first. See par. 7.2.1.
Symbol
A combination of characters including start/stop and checksum characters, as required, that form a complete scannable barcode.
Tilt
Rotation around the Z axis. Used to describe the position of the barcode with respect to the
laser scan line. See pars. 3.2.1 and 3.3.
Trigger Signal
A signal, typically provided by a photoelectric sensor or proximity switch, which informs the scanner of the presence of an object within its reading zone.
UPC
Acronym for Universal Product Code. The standard barcode type for retail food packaging in the United States.
Visible Laser Diode
A light source used in scanners to illuminate the barcode symbol. Generates visible red light at wavelengths between 630 and 680 nm.
