Theory of Operation
During image capture:
1.The image sensor array in the embedded SE4500 imaging engine captures an image of the bar code
through the engine’s optical lens. If necessary, the engine automatically adjusts illumination, exposure, and
other parameters to obtain the best quality image.
2.The imaging engine sends the image to the DS457 CPU.
3.The DS457 CPU processes the image to identify the target bar code(s), decodes them, and transmits the
decoded data to the host.
Set various parameters provided in this guide to adjust the performance of the DS457 to match the application
or desired usage profile.

DS457 Block Diagram Descriptions
SE4500 Imaging Engine - The SE4500 imaging engine captures 8-bit gray scale WVGA images at up to 60
fps, which are sent uncompressed to a companion board for processing. The engine uses a red laser for intuitive
aiming and features LED illumination. The engine is available in two focusing configurations, providing a choice
between high resolution and longer depth of field.
DS457 Decoder/Interface Board - The decoder/interface board is a companion decoder module for the
SE4500 imaging engine, which controls the engine, receives images, decodes 1D and 2D symbologies, and
performs various image processing tasks. The board controls a beeper and red and green LEDs for acoustic
and visual feedback, respectively. It also provides imaging for an external trigger and external beeper via the
DB9 connector. The board supports asynchronous serial (the standard Symbol Simple Serial Interface/SSI
command set) and SNAPI (Symbol Native API) interfaces, as well as a variety of other USB and RS-232 host
interfaces.
DB9 - The DB9 connector provides an outlet for the various interface signals used between the DS457 and the
host. It also provides power to the unit.
DS457 Decoder/Interface Board
Atmel AT91SAM9G20 Processor
The digital system is built on an Atmel AT91SAM9G20, a RISC processor based on ARM v5TEJ architecture.
The major features of the core are:
•
CPU clock speed up to 400 MHz with external LP SDRAM bus speed of 133 MHz
The DS457 decoder/interface board has various power management options depending on the host interface.
•
USB (SNAPI, USB HID Keyboard, etc.) - The DS457 automatically manages its power usage, including
USB suspend mode. Additionally, when drawing power from the USB bus, the DS457 does not exceed
the USB limit of 500 mA.
•
SSI or RS-232 - When using SSI or any RS-232 host interface, the DS457 uses one of the following power
modes. See Power Mode (RS-232 Hosts Only) on page 6-15.
• Continuous Power: The DS457 is fully awake and running, even when not in a decode session.
• Low Power (default): The DS457 draws less current at idle than when in Continuous Power mode.

Serial Interface Cable Connection
When connecting via RS-232, identify the type of host system to determine the cable needed. If you are unsure
what host system you are using, contact the local Zebra representative.
TTL Level Compatible RS-232 Host Systems
If using a PC, laptop, or POS terminal, the host system most likely has an RS-232 port which is compatible with
TTL levels. In this case, use the standard 5V RS-232 cable.
Host Systems Which Require True RS-232 Levels
Some host devices are not compatible with TTL level signals and require true RS-232 levels, such as those in
electrically noisy environments and locations with long cable runs. In such installations the DS457 may require
a level-shifting cable, such as p/n 25-62186-03R, to interface to this host system.
Failure to use the appropriate cable can impact the imager’s ability to reliably communicate with the host under
some conditions.

Male jack shown for reference
Note: Due to many variations of
jack and socket styles, identify
terminals as shown before
soldering leads.
The location and positioning guidelines do not consider unique application characteristics. Zebra recommends
that an opto-mechanical engineer perform an opto-mechanical analysis prior to integration.
NOTE
Integrate the imager in an environment no more extreme than the product’s specification, where the
imager will not exceed its temperature range. For instance, do not mount the imager onto or next to a large
heat source. When placing the imager with another device, ensure there is proper convection or venting
for heat. Follow these suggestions to ensure product longevity, warranty, and overall satisfaction with the
imager.
Embedded Applications Requiring a Window
!
Use the following guidelines for applications that require a window in front of the DS457.
NOTE
Zebra does not recommend placing an exit window in front of the DS457; however, the following
information is provided for applications that require such a window.
Window Material
NOTE
Consider the following window placement and material recommendations if mounting the DS457 within a
product with its own window.
Many window materials that look perfectly clear can contain stresses and distortions that can reduce imager
performance. For this reason, Zebra highly recommends optical glass or cell-cast acrylic. Following is a
description of acrylic and CR-39, another popular window material. Table 2-1 outlines the suggested
window properties.
Installation 2 - 13
CAUTION
NOTE
Consult an opto-mechanical engineer to recommend an appropriate window material and to
determine if coatings are appropriate for the specific application.
Do not use polycarbonate material.
Acrylic (PMMA)
When fabricated by cell-casting, acrylic has very good optical quality and low initial cost. However, protect the
surface from the environment as acrylic is susceptible to attack by chemicals, mechanical stresses, and UV light.
Acrylic has reasonably good impact resistance and can be ultrasonically welded.
CR-39 (ADC)
CR-39 is a thermal-setting plastic produced by the cell-casting process, and is commonly used in plastic eye
glasses lenses. CR-39 has excellent chemical and environmental resistance, including good surface hardness.
Typically it does not require hard-coating, but can be hard coated for severe environments. CR-39 has
reasonably good impact resistance and cannot be ultrasonically welded.
Chemically Tempered Float Glass
Glass is a hard material which provides excellent scratch and abrasion resistance. However, unannealed glass
is brittle. Increasing flexibility strength with minimal optical distortion requires chemical tempering. Glass cannot
be ultrasonically welded and is difficult to cut into odd shapes.

Window Coatings
Table 2-3 lists some exit window manufacturers and anti-reflection coaters.
Anti-Reflection Coatings
Anti-reflection coatings can be used to achieve maximum working range and to improve the range of acceptable
window positions. However, they are expensive. AR coatings also have very poor abrasion and scratch
resistance, making only single-side AR coating practical (the AR coated side of the window faces the interior of
the imager).
Polysiloxane Coating
Apply polysiloxane type coatings to plastic surfaces to improve the surface resistance to both scratch and
abrasion. Typically, you apply these by dipping, then air-drying in an oven with filtered hot air.

If you are placing a window between the DS457 and the target, observe the following guidelines:
•
Window Clear Opening - Make the clear opening of the window large enough so that the entire imager
clear aperture passes through the window. Cutting off any part of the clear aperture can degrade decode
range performance. Ensure that window placement relative to the DS457 accounts for tolerances on all
parts involved in that assembly.
•
Window Angle - Minimum window tilt is indicated in Table 2-4 on page 2-19. Further tilting the window is
acceptable and decreases the possibility of a secondary reflection from that window degrading the
imager's performance.
•
Minimum Window Distance - 5 mm.
•
Optical Working Range - Adding a window can reduce the working range of the imager since there is a
signal loss when passing through window material. To minimize this reduction, use a special coating
described in Window Coatings on page 2-15. To understand the difference, test the imager in the desired
orientation and see if the difference affects imager performance.

CHAPTER 3IMAGING
Overview
This chapter provides information on aiming, illumination, data capture, beeper and decode LED feedback,
supported symbologies, and operating modes.
Imaging System
Aiming Pattern
A 655 nm laser and a pattern forming element generate a laser aiming pattern which represents the imager's
field of view throughout its entire depth of field. The pattern's center dot indicates the center of the field of view.
Figure 3-1
The bright center spot provides visibility for aiming in sunlight and other bright light applications. The aiming
pattern indicates the field of view for capturing images. The ends of the horizontal and vertical lines represent
the midpoints of the sides of an imaginary box outlining the capture field.
Aiming Pattern
Aiming Error
The aiming pattern is rotated by 2o relative to the imaging axis in the horizontal plane to minimize parallax
between the aiming axis and the imaging axis at 190 mm (7.5 in.) from the imager.
3 - 2DS457-XX20004ZZWW Fixed Mount Imager Integration Guide
Aiming Control
The DS457 can capture images with both the aiming subsystem turned on during exposure (the image of the
aiming pattern is visible in the digital image) or off. If the aiming system is turned off during exposure,
brightness of the aiming pattern decreases as exposure increases.
Illumination System
The illumination system consists of two high-output, red LEDs (625 nm) and a sophisticated drive system that
allows image capture and decoding throughout a full range of lighting conditions (total darkness to full
sunlight).
Illumination Control
The DS457 can capture images with the illumination subsystem turned on or off, accommodating images that
are close to the wavelength of the illumination. For example, since the imager uses red LED illumination, it may
be desirable to shut off the illumination when capturing an image printed in red ink.
It is recommended to turn off LED illumination and provide minimum 30 fcd ambient light on the document
surface when taking images of documents. Even a small amount of dust or fingerprints on the imager window
can scatter the LED illumination and create glare in the image. The glare reduces quality of document images
but does not affect bar code reading.
Frame Rate Control
The DS457 outputs images at 60 frames per second by default. When capturing images, use lower frame rates
to increase image brightness. The aiming pattern and illumination appear to blink when the frame rate is 30 fps
or lower.

012345

When scanning, the imager projects a red laser aiming pattern which allows positioning the bar code within its
field of view. See Decode Zones on page 4-6 for the proper distance to achieve between the imager and a bar
code. The imager turns on its red LEDs to illuminate the target bar code.
In Presentation Mode (default), when the DS457 detects an object in its field of view, it automatically triggers
and displays the aiming pattern. In triggered mode, press the trigger button on top of the imager to display the
aiming pattern.
To scan a bar code, center the symbol in any orientation within the aiming pattern. Be sure the entire symbol is
within the rectangular area formed by the cross pattern.

The imager can also read a bar code presented within the aiming pattern but not centered. The top examples
in Figure 3-3 show acceptable aiming options, while the bottom examples can not be decoded.

Upon successful decode, the DS457 beeps and its feedback LED turns green.

Beeper and Decode LED Indications
Table 3-1 provides beeper and LED indications related to certain events. The LED illuminates red to indicate
that the imager has power. SSI events are also listed.

* Above 45ºC the laser aimer is disabled. In high temperature
environments the DS457 safeguards the laser from overheating by
monitoring the internal system temperature. For this reason, if Time
Delay to Presentation Idle Mode is set to a high value and the aiming
pattern remains on for an extended period of time while in
presentation mode, the imager may temporarily shut off the aiming
pattern.

The chapter provides information on maintenance and troubleshooting.
Maintenance
Clean the imager housing and exit window with a damp cloth and, if necessary, a non-ammonia based
detergent. Do not allow any abrasive material to touch the exit window.
Cleaning the Connector
1.Remove the cable connector from the imager.
2.Rub a cotton-tipped applicator dipped in isopropyl alcohol back and forth across the connector pins. Do not
leave any cotton residue on the connector.
3.Rub a dry cotton-tipped applicator back and forth across the connector pins.
4.Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away from the
surface.
5.Inspect the area for any grease or dirt and repeat if required.
CAUTION
Do not get excess alcohol onto the soft elastomeric gasket since this can compromise the adhesion to
the housing and ultimately the gasket’s ability to prevent liquids from entering the imager in this area
during normal operation.

CHAPTER 6USER PREFERENCES
Introduction
This chapter describes each user preference feature and provides the programming bar codes necessary for
selecting these features.
Host Selection
The default serial host is SSI and the default USB host is USB HID Keyboard, as these host types provide
more flexibility during integration when configuring the unit via host command. Selecting other host
configurations requires scanning bar code menus and cannot be performed via host programming. See each
host chapter for configuration options for each host type.
NOTE
The DS457 automatically switches between USB and serial host interfaces based on the type of cable
attached.
NOTE
Selecting one of the Serial Host Types on page 9-5 disables SSI support. To restore SSI support, scan
SSI Host on page 8-9.
6 - 2DS457-XX20004ZZWW Fixed Mount Imager Integration Guide
Changing Default Values
The imager ships with the settings shown in the Table 6-1 on page 6-3 (also see Appendix A, Standard Default
Parameters for all host and miscellaneous defaults). If the default values suit requirements, programming is not
necessary.
There are two ways to change a parameter value:
•
Scan the appropriate bar codes in this guide. These new values replace the standard default values in
memory.
•
For SSI and USB SNAPI hosts, send a “parameter send” command from the host system. Hexadecimal
parameter numbers appear in this chapter below the parameter title, and options appear in parenthesis
beneath the accompanying bar codes. See the Simple Serial Interface (SSI) Programmer’s Guide for
detailed instructions for changing parameter values using this method.
NOTE
Most computer monitors allow scanning the bar codes directly on the screen. When scanning from the
screen, be sure to set the document magnification to a level where you can see the bar code clearly, and
bars and/or spaces are not merging.
To return all features to default values, scan *Restore Defaults on page 6-5. Throughout the programming bar
code menus, asterisks (
*) indicate default values.
* Indicates default
*High Volume
Scanning Sequence Examples
In most cases, scanning one bar code sets the parameter value. For example, to set the beeper tone to high,
scan the High Frequency (beeper tone) bar code listed under Beeper Tone on page 6-9. The imager issues a
fast warble beep signal and a good decode LED signal, signifying a successful parameter entry.
Other parameters, such as Decode Session Timeout, require scanning several bar codes. See these
parameter descriptions for this procedure.
Errors While Scanning
Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.

Parameter # 236 (SSI # ECh)
To disable the decoding of parameter bar codes, including the Set Defaults parameter bar codes, scan the
Disable Parameter Scanning bar code below. To enable decoding of parameter bar codes, scan Enable
Parameter Scanning.
This feature locks parameter settings with a 4-digit code to prevent the user from changing parameter values
by scanning parameter bar codes. This provides an added level of security not offered via Disable Parameter Scanning.
After locking parameter settings, the only the Unlock parameter bar code is accepted, with the correct code.
NOTE
Parameter Scanning must be enabled in order to scan the Lock parameter bar code. Once parameter
scanning is locked, scanning the Enable or Disable Parameter Scanning bar code results in a parameter
error beep.
1.To lock parameter scanning:
2.Scan the Lock bar code.
3.Scan four bar codes from Appendix G, Numeric Bar Codes that represent the desired code. Enter leading
zeros for numbers below 1000, e.g., to program a code of 29, enter 0, 0, 2, 9. A lock beep sounds (two
long high beeps) in addition to the parameter entry beep.
To unlock parameter scanning:
1.Scan the Unlock bar code.
2.Scan four bar codes from Appendix G, Numeric Bar Codes that represent the correct code. An unlock beep
sounds (two long low beeps) in addition to the parameter entry beep. Entering an incorrect code results in
a parameter error beep.

Locking/Unlocking via the Host Interface
Parameter scanning can also be locked or unlocked using a host interface such as SSI or USB SNAPI.
To lock parameter scanning using the host interface, store a 4-digit code within the range of 1-9999 in the Lock
parameter. Values outside this range are ignored. To unlock parameter scanning, store this code in the Unlock
parameter. To persist the lock/unlock status through a power cycle, make this parameter value permanent.
NOTE
Parameter values can be changed via host interface commands even when parameter scanning is locked.

Presentation Performance Mode
Parameter # 650 (SSI # F1h 8Ah)
Select one of the following Presentation Performance Mode options:
•
Standard Presentation Mode is optimized for general purpose scanning, i.e., reading bar codes from
standard surfaces such as paper labels or hang tags. This mode balances bar code swipe speed (the
speed a bar code can pass through the field of view and still be read) and decode range (distance
between the imager and the bar code) for optimal performance on standard paper-based bar codes.
•
Enhanced Presentation Mode is also optimized for general purpose (paper-based) scanning but
provides for a faster bar code swipe speed and shorter decode range than
This mode is recommended for applications requiring the highest bar code swipe speed (e.g., automated
scanning) or a reduced decode range (e.g., to better match EAS deactivation range or reduce the
occurrence of inadvertent reads during hands-free operation).
•
Traditional Presentation Mode is optimized for applications that require frequent reading of bar codes
from mobile phones or PC displays, and improves performance on large 2D symbols. This mode allows
more time for the imager to analyze each bar code, improving performance on challenging bar codes
such as those on a mobile phone display where the backlight has dimmed. This mode is also
recommended for applications that include many truncated or poor quality bar codes. Because swipe
speed is reduced, present bar codes to the imager rather than swiping them when using this mode.

PDF Prioritization
Parameter # 719 (SSI # F1h CFh)
Enable this feature to delay decoding a 1D bar code (Code 128) by the value specified in PDF Prioritization
Timeout. During that time the imager attempts to decode a PDF417 symbol (e.g., on a US driver's license), and
if successful, reports this only. If it does not decode (can not find) a PDF417 symbol, it reports the 1D symbol
after the timeout. The 1D symbol must be in the device’s field of view for the imager to report it. This parameter
does not affect decoding other symbologies..
NOTE
The 1D Code 128 bar code lengths include the following:
• 7 to 10 characters
• 14 to 22 characters

Parameter # 1438 (SSI # F8h 05h 9Eh)
NOTE
If you enable a DPM Mode, the decoder behaves as if the Data Matrix Inverse Autodetect setting is
selected.
Unlike bar codes typically printed on labels, a direct part mark (DPM) is a symbol that is marked directly on an
item's surface for permanent identification, using methods such as laser etching, dot peening, or
direct-printing.
Select one of the following DPM modes based on the type of bar code being scanned. There are two DPM
modes which are recommended for different sets of bar code characteristics. The combinations of these
characteristics vary and it is recommended that all modes are tested on the target bar code to determine the
best mode for the application.
•
Disable DPM Mode - No special processing occurs.
•
DPM Mode 1 - Optimizes decoding performance on smaller DPM bar codes, typically found on
electronics and medical instruments, especially on smooth surfaces. These bar codes tend to be laser
etched or direct-printed.
•
DPM Mode 2 - Optimizes decoding performance on larger DPM bar codes, typically found on industrial
parts, especially on rough, grainy, or visibly machined surfaces. These bar codes tend to be dot-peened
or laser etched.

prefix or suffix, scan the prefix or suffix bar code below, then scan a four-digit number (i.e., four bar codes from
Appendix G, Numeric Bar Codes) that corresponds to that value. The first digit defines the key category (type
of character to send) and is stored in the key category parameter. The remaining three digits define the value
of the character and are stored in the decimal value parameter. Be sure to use both key category and decimal
value parameters to define the prefix/suffix value.

CHAPTER 7IMAGER PREFERENCES
Introduction
This chapter describes imager preference features and provides the programming bar codes for selecting
these features.
The imager ships with the settings shown in the Imager Preferences Default Table on page 7-2 (also see
Appendix A, Standard Default Parameters for all host and miscellaneous defaults). If the default values suit
requirements, programming is not necessary.
There are two ways to change a parameter value:
•
Scan the appropriate bar codes in this guide. These new values replace the standard default values in
memory.
•
For SSI and USB SNAPI hosts, send a “parameter send” command from the host system. Hexadecimal
parameter numbers appear in this chapter below the parameter title, and options appear in parenthesis
beneath the accompanying bar codes. See the Simple Serial Interface (SSI) Programmer’s Guide for
detailed instructions for changing parameter values using this method.
NOTE
Most computer monitors allow scanning the bar codes directly on the screen. When scanning from the
screen, be sure to set the document magnification to a level where you can see the bar code clearly, and
bars and/or spaces are not merging.
Select a host type (see each host chapter for specific host information) after the power-up beep signal
activates. This is only necessary upon the first power-up when connected to a new host.
To return all features to default values, scan the Set Default Parameter on page 6-5. Throughout the
programming bar code menus, asterisks (
* Indicates default
*Enable Decode Aiming Pattern
*) indicate default values.

Scanning Sequence Examples
In most cases scanning one bar code sets the parameter value. For example, to disable the decode aiming
pattern, scan the Disable Decode Aiming Pattern bar code listed under Decode Aiming Pattern on page 7-6.
For systems that use a beeper and LED, a fast warble beep sounds and the LED lights, signifying a successful
parameter entry.
Other parameters, such as Crop to Pixel Address, require scanning several bar codes. See these parameter
descriptions for this procedure.
Errors While Scanning
Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.
Imager Preferences Parameter Defaults
Table 7-1 lists defaults for imager preferences parameters. To change any option, scan the appropriate bar
code(s) provided in Imager Preferences on page 7-4.

Imager Preferences
The parameters in this chapter control image capture characteristics. Image capture occurs in all modes of
operation, including decode, video, and snapshot.
Operational Modes
The imager has three modes of operation:
•
Decode Mode
•
Snapshot Mode
• Snapshot with Viewfinder Mode
•
Video Mode.
Decode Mode
By default, upon a trigger event, the imager attempts to locate and decode bar codes within its field of view.
The imager remains in this mode as long as the trigger is active, until it decodes a bar code, or it reaches the
Decode Session Timeout on page 6-17.
Snapshot Mode
Use Snapshot Mode to capture a high-quality image and transmit it to the host. To temporarily enter this mode
scan the Snapshot Mode bar code. While in this mode the imager blinks the green LED at 1-second intervals
to indicate it is not in standard operating (decode) mode.
In Snapshot Mode, the DS457 laser aiming pattern highlights the area to capture in the image. The next trigger
event instructs the imager to capture a high quality image and transmit it to the host. A short time may pass
(less than 2 seconds) between trigger activation and image capture as the imager adjusts to the lighting
conditions. Hold the imager steady until image capture, denoted by a single beep.
If a trigger event does not occur within the Snapshot Mode Timeout period, the imager returns to Decode
Mode. Use Snapshot Mode Timeout on page 7-14 to adjust this timeout period. The default timeout period is
30 seconds.
To disable the laser aiming pattern during Snapshot Mode, see Snapshot Aiming Pattern on page 7-14.
Use Video View Finder on page 7-30 to enable Snapshot with Viewfinder Mode. In this mode the imager
behaves as a video camera until the trigger activates, at which time a Snapshot occurs as described above.
