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.

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.

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 Motorola Solutions 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.

Location and Positioning
The location and positioning guidelines do not consider unique application characteristics. Motorola
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.
Installation 2 - 11
Embedded Applications Requiring a Window
Use the following guidelines for applications that require a window in front of the DS457.
NOTE
Motorola 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, Motorola 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.
!
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.

Embedded Window Angle and Position
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 2-15. 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 2-12. To understand the difference, test the imager in the desired
orientation and see if the difference affects imager performance.

CHAPTER 3 IMAGING
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 Aiming Pattern
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 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.
3-2
DS457 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.
Imaging
3-3
Capturing Data
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.

Figure 3-2 Scanning Orientation with Imager Aiming 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.

CHAPTER 5 MAINTENANCE &
TROUBLESHOOTING
Overview
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.

NOTE
If after performing these checks the symbol still does not decode, contact the distributor or contact
Motorola Enterprise Mobility Support. See page xviii for contact information.
CHAPTER 6 USER 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 Standard RS-232 with SSI and the default USB host is HID Keyboard Emulation, 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 Standard RS-232 with
SSI support, scan SSI Host on page 8-9.
Phantom Scan Session
The Phantom Scan Session feature places the system into a known state for two seconds immediately after
the power-up beep sequence in order to decode a parameter bar code without intervention and regardless of
existing settings and mode. This allows you to scan a Set Defaults or other parameter bar code without
triggering the imager or initiating a host scan session in order to return an unresponsive system to its factory
default settings. Aim and illumination are turned off and Phantom Scan exits upon a trigger event, host
command, or successful decode.
6-2
DS457 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
Feature/Option
(00h)
Option Hex Value for programming

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.

Trigger Mode
Parameter # 8Ah
• Level - A trigger event activates decode processing, which continues until the trigger event ends, a valid
decode, or the decode session time-out occurs.
• Presentation Mode - When the DS457 detects an object in its field of view, it triggers and attempts to
decode. The range of object detection does not vary under normal lighting conditions. This applies to
decode mode only. In this mode the unit does not enter Low Power mode.
• Host - A host command issues the triggering signal. The DS457 interprets a trigger pull as a level
triggering option.
• Software Trigger Only Mode - This option disables the hardware trigger so that only a host command
can issue the triggering signal. This is interpreted as a level trigger option.

Multicode Expression
Parameter # F1h, 95h
Use this feature to program a multicode expression for Multicode Mode (grid method). The default is 1, which
indicates any bar code.
To set the multicode expression:
1.
Scan the bar code below.
2.
Scan bar codes from the Alphanumeric Keyboard in the Advanced Data Formatting Programmer Guide.
3.
Scan End of Message in the Advanced Data Formatting Programmer Guide.
Multicode Expression
Multicode Expression Syntax: [n] [Element 1]; [Element 2 ]; ... [Element n];
Where n is the number of elements in the overall expression.
The multicode expression describes the bar code(s) that the imager can expect to find in an image. Each
element represents one bar code in the DS457's field of view. The order of elements in the expression is the
order in which bar code data from each element transmits to the host. Elements are defined using one or more
of the following methods:
By Region. This type of element limits decoding to a specific area within the DS457's field of view. Region
coordinates are defined as the top left and bottom right corners of the region, expressed in percentages of the
field of view. These can range from 0% to 100%, or 0x00 to 0x64 in hex, for both horizontal and vertical axes.
A region element is constructed as:
[R] [4] [Top, Left] [Bottom, Right]
Where:
• [R] is the character R
• [4] is 0x04, indicating there are four bytes thereafter to describe the region
• [Top, Left] are two values representing the top left corner of the region
• [Bottom, Right] are two values representing the bottom right corner of the region
Note that the top of the field of view used for multicode expressions is the topmost part of the field of view when
the DS457's chassis rests on a horizontal surface.
6 - 24 DS457 Fixed Mount Imager Integration Guide
By Code Type. An element can specify a specific bar code symbology to find and decode somewhere in the
field of view. A code type element is constructed as:
[C] [2] [Code Type]
Where:
• [C] is the character C
• [2] is 0x02, indicating there are two bytes thereafter to describe the code type
• [Code Type] is the desired symbology's parameter number (see Chapter 12, Symbologies). For
single-byte parameter numbers, extend the value to two bytes by adding 00 before the parameter
number.
Notes
When defining multicode expressions consider the following:
• Use the Code Type specifier if there are bar codes of more than one code type in view.
• Always use the Region specifier when there are multiple bar codes of the same code type.
• When transmission order is important (the first element in the expression transmits first), use either type
to define the order.
• When there are unwanted bar codes in view, filter them out in one of two ways:
• Use Code Type to specify only the target bar codes.
• Use Region to identify only the target bar codes.
• If the expression does not contain a Region specifier, scanning angle and distance do not matter. If you
specify a region you must scan in a fixed orientation and at a fixed distance. Because of this, it is
preferable to use the Code Type specifier rather than the Region specifier.
• When defining regions:
• Defining a region much larger than the bar code improves tolerance to scan distance and angle, but
can cause a decode of a nearby bar code instead of the target bar code. Therefore, for best
performance define larger regions when only a few bar codes are in view and those in view are widely
separated.
• Defining a region close to (or smaller than) the target bar code improves the probability of decoding
this bar code rather than one nearby, but scan distance and angle must be more accurate. Therefore,
for best performance define small regions when many bar codes are in view or those in view are close
together.
• Use Region elements to improve decode speeds by reducing the image area to search for the target bar
code.
• Specifying Code Type may also improve decode speeds for some code types.
• Although you can scan parameter bar codes when multicode mode is enabled, be aware of the following:
If the multicode expression defined a region(s), to scan a parameter bar code you must position the bar
code within the first region defined in the expression. In some cases, this first region is not the center of
the image and aiming at the parameter bar code does not result in a successful decode.
The following examples show the multicode expressions in both hex and decimal formats, however in the
sample figures the values are decimal. Be sure to use the correct base numbering system when creating an
expression. A region specified as 0x00 0x00 0x64 0x32 represents a region with coordinates of Top-Left (0,0)
and Bottom Right (100,50).

Programming a Multicode Expression via SSI Command
The following example describes how to program a Multicode expression via SSI within a Remote Scanner
Management (RSM) command.
SSI Transaction Sequences
Before sending the Multicode expression transaction (a command/response pair), perform the following
initialization transaction (command and response). This initialization transaction is required only once upon
each imager power up:
Command (to imager):
0A 80 04 00 00 06 20 00 00 FF FE 4D
Response (from imager):
0C 80 00 00 00 08 20 00 00 F0 00 F0 FD 6C
Next, program the Multicode Expression using the following basic transaction format.
Command (to imager):
Hex] FD A3
17 80 04 00 00 13 06 00 02 95 41 00 42 00 06 00 [Multicode Expression in
Response (from imager):

For full details on structuring Multicode expression commands, see Figure 6-4.
Legend for Figure 6-4
• All values in the table are hex, unless followed by a d which indicates decimal.
• Shaded fields represent values that change for different Multicode expressions.
Unshaded fields are fixed and are constant for all expressions.
• N: The length of the Multicode expression in bytes. Using Example 1, N = 6 decimal, 0x06 hex.
• Len1: N+17. Using Example 1, Len1 = 23 decimal, 0x17 hex.
• Len2: N+13. Using Example 1, Len2 = 19 decimal, 0x13 hex.
• Op: Command persistence.
• 0x06 stores the Multicode expression in non-volatile memory. The command persists through power
cycling.
or
• 0x05 stores the Multicode expression in RAM. The command is lost when power is removed from the
imager.
• Len4: Same value as N. Using Example 1, Len4 = 6 decimal, 0x06 hex.
• Checksum: 2's compliment checksum of bytes in the SSI Header and SSI Data. Sum all bytes, truncate
to a 2 byte value, subtract this value from 0x10000; the resulting number is the 2 byte checksum. Using
Example 1 the checksum is FDA3.

Multicode Troubleshooting
Troubleshooting Multicode Expression Programming
Use the following suggestions if encountering problems programming a multicode expression:
• Ensure the expression is valid. Invalid expressions are rejected during programming. When an
expression is rejected the previous expression remains intact. If after programming the expression the
imager can still decode any bar code, the expression was possibly rejected.
• When programming the multicode expression via parameter bar code, the DS457 generates beeps. If
any of the following beeps do not sound during programming, an error occurred (see Table 3-1 on page
3-4 for error indicators):
• Scanning the Multicode Expression bar code produces a two-tone (same pitch) beep.
• Scanning each value of the expression produces a two-tone (same pitch) beep.
• Scanning the End Of Message bar code produces a four-tone (high-low-high-low) beep.
• Check the expression for syntax errors.
• Try programming a simple expression to ensure the syntax is correct. See Examples of Simple Multicode
Expressions.
• Review Notes on page 6-24 for additional hints.
Troubleshooting Multicode Mode Scanning and Decoding
Use the following suggestions if encountering problems using multicode mode:
• If the DS457 appears to decode any single bar code instead of the intended multiple bar codes, ensure
you enabled Multicode Mode on page 6-22. Programming the multicode expression does not enable
multicode mode.
• When specifying Region, ensure:
• Coordinates are within range the 0-100 decimal (or 0x00 - 0x64 hexadecimal).
• Top, Left is above Bottom, Right. Top, Left is 0,0 (0x00, 0x00 hexadecimal), and Bottom, Right is
100,100 (0x64, 0x64 hexadecimal).
• Regions for two or more bar codes do not overlap.
• When specifying Code Type ensure the DS457 supports the code type. Try decoding a single bar code
without using multicode. If it does not decode try enabling the bar code type. See Chapter 12,
Symbologies.
• Experiment with simpler expressions, then add to it until you discover the source of the error. For
example try the simplest expression (see Examples of Simple Multicode Expressions) and make sure
you can scan a single bar code. If so, extend the expression by adding a second bar code, specifying a
region, or specifying the code type. Verify that the DS457 can decode this new expression. Continue
adding to the expression until it fails to decode as expected, indicating the source of the error.
• Review Notes on page 6-24 for additional hints.

CHAPTER 7 IMAGER 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 (*) indicate default values.

DS457 Fixed Mount Imager Integration Guide
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.

DS457 Fixed Mount Imager Integration Guide
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 7-13 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 7-13.
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.
Imager Preferences
7-5
Video Mode
In this mode the imager behaves as a video camera as long as the trigger is active. Upon trigger release, the
imager returns to Decode Mode. Scan the Video Mode bar code to temporarily enter Video Capture Mode.
NOTE
The DS457 does not support Video Mode when Trigger Mode on page 6-11 is set to Presentation Mode
(the default).

Aim Brightness
Parameter # F1h 9Ch
This feature sets the brightness of the aim pattern. The default is 0, which indicates that the aim pattern is
always on in between camera exposures. For values above 0, each increment of the brightness value
increments the aim duration 0.5 ms.
To program Aim Brightness, scan this bar code followed by three numeric bar codes in Appendix D, Numeric
Bar Codes that correspond to the value representing brightness. Settings range from 0 to 255. The maximum
aim duration is limited by the frame time, so the recommended range is 0 to 30 when the frame rate is set to 60
fps.
Aim Brightness
Illumination Brightness
Parameter # F1h 9Dh
This feature sets the brightness of the illumination by altering LED power. The default is 10, which is maximum
LED brightness. For values from 1 to 10, LED brightness varies from lowest to highest level of brightness.
To program Illumination Brightness, scan this bar code followed by two numeric bar codes in Appendix D,
Numeric Bar Codes that correspond to the value of desired illumination brightness. For example, to set
Illumination Brightness to 6, scan the bar code below followed by the 0 and 6 bar codes.

Fixed Gain
Parameter # F1h 38h
This parameter only applies when Decoding or Image Capture Autoexposure is disabled. Gain is a means of
amplifying the raw image data before it is converted into 8-bit grayscale values. Increasing the fixed gain
increases brightness and contrast, but also increases noise (undesired electrical fluctuations in the image)
which makes the image less attractive and/or harder to decode.
To set the fixed gain, scan the bar code below followed by 3 bar codes from Appendix D, Numeric Bar Codes,
in the range of 1 to 100, representing the value. The default is 50.
Fixed Gain
Exposure Time
Parameter # F4h F1h 37h
This parameter only applies when Decoding or Image Capture Autoexposure is disabled. It configures the
exposure for both Decode and Snapshot modes.
Each integer value represents 100 μs worth of exposure. The default value is 100 which results in an exposure
setting of 10 ms.
To set the Exposure Time parameter, scan Fixed Exposure followed by four numeric bar codes representing
the value in the range of 1 - 1000. Insert leading zeros if necessary. For example, to set a Fixed Exposure
value of
9.9 ms, scan 0, 0, 9, 9. See Appendix D, Numeric Bar Codes for numeric bar codes.

Parameter # F4h F0h 3Eh (Right)
If Enable Image Cropping is selected, set the pixel addresses from (0,0) to (751,479) to crop to.
Columns are numbered from 0 to 751, rows from 0 to 479. Specify four values for Top, Left, Bottom, and Right,
where Top and Bottom correspond to row pixel addresses, and Left and Right correspond to column pixel
addresses. For example, for a 4 row x 8 column image in the extreme bottom-right section of the image, set the
following values:
Top = 476, Bottom = 479, Left = 744, Right = 751
To set the pixel address to crop to, scan each Pixel Address bar code followed by three bar codes from
Appendix D, Numeric Bar Codes which represent the value. Include leading zeros, so to enter a value of 3, for
example, scan 0, 0, 3.
NOTE
The imager has a minimum cropping resolution of four pixels; increment and decrement cropping
addresses in multiples of four. Other values are rounded up. For example, choosing to crop from the top at
addresses 0, 1, or 2 (removing 1, 2, or 3 pixels) has the same result as cropping at address 3; this
removes four rows from the top.

CHAPTER 8 SSI INTERFACE
Introduction
This chapter describes the system requirements of the Simple Serial Interface (SSI), which provides a
communications link between Motorola decoders (e.g., scan engines, imagers, hand-held scanners,
two-dimensional scanners, hands-free scanners, and RF base stations) and a serial host. It provides the
means for the host to control the imager.
Communications
All communication between the imager and host occurs over the hardware interface lines using the SSI
protocol. Refer to the Simple Serial Interface Programmer’s Guide, p/n 72-40451-xx, for more information on
SSI.
The host and the imager exchange messages in packets. A packet is a collection of bytes framed by the proper
SSI protocol formatting bytes. The maximum number of bytes per packet that the SSI protocol allows for any
transaction is 257 (255 bytes + 2 byte checksum).
Decode data can be sent as ASCII data (unpacketed), or as part of a larger message (packeted), depending on
the imager configuration.
SSI performs the following functions for the host device:
• Maintains a bi-directional interface with the imager
• Allows the host to send commands that control the imager
• Passes data from the imager to a host device in SSI packet format or straight decode message.
The working environment of the SSI consists of an imager, a serial cable which attaches to the host device,
and in some instances, a power supply.
SSI transmits all decode data including special formatting (e.g., AIM ID). Parameter settings can control the
format of the transmitted data.
The imager can also send parameter information, product identification information, or event codes to the host.
All commands sent between the imager and host must use the format described in the SSI Message Formats
section. SSI Transactions on page 8-3 describes the required sequence of messages in specific cases.
8-2
DS457 Fixed Mount Imager Integration Guide
Table 8-1 lists all the SSI opcodes the imager supports. It identifies the SSI partner allowed to send a message
of each type. The host transmits opcodes designated type H. The imager transmits type D opcodes, and either
partner can transmit Host/Decoder (H/D) types.

SSI Transactions
General Data Transactions
ACK/NAK Handshaking
If you enable ACK/NAK handshaking, all packeted messages must have a CMD_ACK or CMD_NAK response,
unless the command description states otherwise. This parameter is enabled by default. Motorola
recommends leaving this handshaking enabled to provide feedback to the host. Raw decode data and
WAKEUP do not use ACK/NAK handshaking since they are not packeted data.
Following is an example of a problem which can occur if you disable ACK/NAK handshaking:
• The host sends a PARAM_SEND message to the imager to change the baud rate from 9600 to 19200.
• The imager cannot interpret the message.
• The imager does not implement the change the host requested.
• The host assumes that the parameter change occurred and acts accordingly.
• Communication is lost because the change did not occur on both sides.
If you enable ACK/NAK handshaking, the following occurs:
• The host sends a PARAM_SEND message.
• The imager cannot interpret the message.
• The imager CMD_NAKs the message.
• The host resends the message.
• The imager receives the message successfully, responds with CMD_ACK, and implements parameter
changes.
8-4
DS457 Fixed Mount Imager Integration Guide
Transfer of Decode Data
The Decode Data Packet Format parameter controls how decode data is sent to the host. Set this parameter to
send the data in a DECODE_DATA packet. Clear this parameter to transmit the data as raw ASCII data.
NOTE
When transmitting decode data as raw ASCII data, ACK/NAK handshaking does not apply regardless of
the state of the ACK/NAK handshaking parameter.
ACK/NAK Enabled and Packeted Data
The imager sends a DECODE_DATA message after a successful decode. The imager waits for a
programmable time-out for a CMD_ACK response. If it does not receive the response, the imager tries to send
two more times before issuing a host transmission error. If the imager receives a CMD_NAK from the host, it
may attempt a retry depending on the cause field of the CMD_NAK message.

Communication Summary
RTS/CTS Lines
All communication must use RTS/CTS handshaking as described in the Simple Serial Interface Programmer’s
Guide, p/n 72-40451-xx. If hardware handshaking is disabled or bypassed, the WAKEUP command must be
sent prior to all other communications, or the first byte of a communication message may be lost during the
imager wakeup sequence.
ACK/NAK Option
Enable or disable ACK/NAK handshaking. This handshaking is enabled by default and Motorola recommends
leaving it enabled. Disabling this handshaking can cause communication problems, as handshaking is the only
acknowledgment that a message was received, and if it was received correctly. ACK/NAK is not used with
unpacketed decode data regardless of whether or not it is enabled.
Number of Data Bits
All communication with the imager must use 8-bit data.
Serial Response Time-out
The Serial Response Time-out parameter determines how long to wait for a handshaking response before
trying again, or aborting any further attempts. Set the same value for both the host and imager.
NOTE
You can temporarily change the Serial Response Time-out when the host takes longer to process an ACK
or longer data string. Motorola does not recommend frequent permanent changes due to limited write
cycles of non-volatile memory.
Retries
When sending data, the host should resend twice after the initial send if the imager does not respond with an
ACK or NAK (if ACK/NAK handshaking is enabled), or response data (e.g., PARAM_SEND,
REPLY_REVISION). If the imager replies with a NAK RESEND, the host resends the data. All resent
messages must have the resend bit set in the Status byte.
The imager resends data two times after the initial send if the host fails to reply with an ACK or NAK (if
ACK/NAK handshaking is enabled).
8-6
DS457 Fixed Mount Imager Integration Guide
Baud Rate, Stop Bits, Parity, Response Time-out, ACK/NAK Handshake
If you use PARAM_SEND to change these serial parameters, the ACK response to the PARAM_SEND uses
the previous values for these parameters. The new values then take effect for the next transaction.
Errors
The imager issues a communication error when:
• The CTS line is asserted when the imager tries to transmit, and is still asserted on each of 2 successive
retries
• Failure to receive an ACK or NAK after initial transmit and two resends.
Things to Remember When Using SSI Communication
When not using hardware handshaking, space messages sufficiently apart. The host must not communicate
with the imager if the imager is transmitting.
When using hardware handshaking, frame each message properly with the handshaking signals. Do not try to
send two commands within the same handshaking frame.
There is a permanent/temporary bit in the PARAM_SEND message. Removing power from the imager
discards temporary changes. Permanent changes are written to non-volatile memory. Frequent changes
shorten the life of the non-volatile memory.

SSI interprets Prefix, Suffix1, and Suffix2 values listed in Table E-1 on page E-1 differently than other
interfaces. SSI does not recognize key categories, only the 3-digit decimal value. The default value of
7013 is interpreted as CR only.
SSI Host Parameters

Parity
Parameter # 9Eh
A parity check bit is the most significant bit of each ASCII coded character. Select the parity type according to
host device requirements.
• Select Odd parity and the parity bit has a value 0 or 1, based on data, to ensure that an odd number of 1
bits is contained in the coded character.
• Select Even parity and the parity bit has a value 0 or 1, based on data, to ensure that an even number of
1 bits is contained in the coded character.
• If no parity is required, select None.

(01h)
Software Handshaking
Parameter # 9Fh
This parameter offers control of data transmission in addition to the control hardware handshaking offers.
Hardware handshaking is always enabled; you cannot disable it.
• Disable ACK/NAK Handshaking: When this option is selected, the imager neither generates nor
expects ACK/NAK handshaking packets.
• Enable ACK/NAK Handshaking: When this option is selected, after transmitting data, the imager
expects either an ACK or NAK response from the host. The imager also ACKs or NAKs messages from
the host.
The imager waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK. If
the imager does not get a response in this time, it resends its data up to two times before discarding the
data and declaring a transmit error.
Disable ACK/NAK

SSI Interface 8 - 13
Host RTS Line State
Parameter # 9Ah
This parameter sets the expected idle state of the Serial Host RTS line.
The SSI Interface is used with host applications which also implement the SSI protocol. However, you can use
the imager in a "scan-and-transmit" mode to communicate with any standard serial communication software on
a host PC (see Decode Data Packet Format on page 8-13). If transmission errors occur in this mode, the host
PC may be asserting hardware handshaking lines which interfere with the SSI protocol. Scan the Host: RTS
High bar code to address this problem.
*Host: RTS Low
(00h)
Host: RTS High
(01h)
Decode Data Packet Format
Parameter # EEh
This parameter selects whether to transmit decoded data in raw format (unpacketed), or with the packet format
defined by the serial protocol.
Selecting the raw format disables ACK/NAK handshaking for decode data.
*Send Raw Decode Data
(00h)
Send Packeted Decode Data
(01h)
8 - 14 DS457 Fixed Mount Imager Integration Guide
Host Serial Response Time-out
Parameter # 9Bh
This parameter specifies how long the imager waits for an ACK or NAK before resending. Also, if the imager
wants to send, and the host has already been granted permission to send, the imager waits for the designated
time-out before declaring an error.
To set the delay period (options are 2, 5, 7.5, or 9,9 seconds), scan one of the following bar codes.
NOTE
Other values are available via SSI command.
*Low - 2 Seconds
(14h)
Medium - 5 Seconds
(32h)
High - 7.5 Seconds
(4Bh)
Maximum - 9.9 Seconds
(63h)
SSI Interface 8 - 15
Host Character Time-out
Parameter # EFh
This parameter determines the maximum time the imager waits between characters transmitted by the host
before discarding the received data and declaring an error.
To set the delay period (options are 200, 500, 750, or 990 ms), scan one of the following bar codes.
NOTE
Other values are available via SSI command.
*Low - 200 ms
(14h)
Medium - 500 ms

8 - 16 DS457 Fixed Mount Imager Integration Guide
Multipacket Option
Parameter # F0h, 4Eh
This parameter controls ACK/NAK handshaking for multi-packet transmissions.
• Multi-Packet Option 1: The host sends an ACK / NAK for each data packet during a multi-packet
transmission.
• Multi-Packet Option 2: The imager sends data packets continuously, with no ACK/NAK handshaking to
pace the transmission. The host, if overrun, can use hardware handshaking to temporarily delay imager
transmissions. At the end of transmission, the imager waits for a CMD_ACK or CMD_NAK.
• Multi-Packet Option 3: Option 3 is the same as option 2 with the addition of a programmable interpacket
delay.
*Multipacket Option 1
(00h)
Multipacket Option 2

CHAPTER 9 SERIAL INTERFACE
Introduction
This chapter describes how to set up the imager with a serial host. The serial interface connects the imager to
point-of-sale devices, host computers, or other devices with an available serial port (e.g., com port).
If the host is not listed in Table 9-2, refer to the documentation for the host device to set communication
parameters to match the host.
NOTE
The imager uses TTL signal levels, which interface with most system architectures. System architectures
that use RS-232C signal levels require conversion circuitry.
Throughout the programming bar code menus, asterisks (*) indicate default values.
* Indicates Default
NOTE
*Baud Rate 57,600
Feature/Option
The serial host type is automatically selected when a serial cable is attached, and typically requires
scanning bar code menus as part of initial configuration.
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.
CAUTION
The DS457 wakes from low power mode upon receiving a character. However, the DS457 does not
process this character or any others it receives during the 7 ms period following wakeup. Wait at least
7 ms after wakeup to send valid characters.

Serial Host Types
To select a serial host interface, scan one of the following bar codes.
NOTE
Scanning Standard RS-232 activates the serial driver, but does not change port settings (e.g., parity, data
bits, handshaking). Selecting another serial host type bar code changes these settings.
NOTE
Selecting one of the Serial Host Types disables SSI support. To restore Standard RS-232 with SSI
support, scan SSI Host on page 8-9.

Serial Interface 9 - 11
Hardware Handshaking
The data interface consists of a serial port designed to operate either with or without the hardware
handshaking lines Request to Send (RTS) and Clear to Send (CTS).
If Standard RTS/CTS handshaking is not selected, scan data transmits as it becomes available. Select
Standard RTS/CTS handshaking to transmit scan data according to the following sequence:
• The imager reads the CTS line for activity. If CTS is asserted, the imager waits up to the Host Serial
Response Time-out for the host to de-assert the CTS line. If, after the Host Serial Response Time-out
(default) the CTS line is still asserted, the imager sounds a transmit error and discards any scanned data.
• When the CTS line is de-asserted, the imager asserts the RTS line and waits up to the Host Serial
Response Time-out for the host to assert CTS. When the host asserts CTS, data transmits. If, after the
Host Serial Response Time-out (default) the CTS line is not asserted, the imager sounds a transmit error
and discards the data.
• When data transmission completes, the imager de-asserts RTS 10 msec after sending the last character.
• The host responds by negating CTS. The imager checks for a de-asserted CTS upon the next
transmission of data.
During data transmission, the CTS line should be asserted. If CTS is deasserted for more than 50 ms between
characters, the imager aborts transmission, sounds a transmission error, and discards the data.
If the above communication sequence fails, the imager issues an error indication. In this case, the data is lost
and must be rescanned.
If hardware handshaking and software handshaking are both enabled, hardware handshaking takes
precedence.
NOTE
The DTR signal is jumpered to the active state.
• None: Scan this bar code to disable hardware handshaking.
• Standard RTS/CTS: Scan this bar code to select Standard RTS/CTS Hardware Handshaking.
• RTS/CTS Option 1: The imager asserts RTS before transmitting and ignores the state of CTS. The
imager de-asserts RTS when transmission completes.
• RTS/CTS Option 2: RTS is always high or low (user-programmed logic level). However, the imager waits
for CTS to be asserted before transmitting data. If CTS is not asserted within Host Serial Response
Time-out (default), the imager issues an error indication and discards the data.
• RTS/CTS Option 3: The imager asserts RTS prior to any data transmission, regardless of the state of
CTS. The imager waits up to Host Serial Response Time-out (default) for CTS to be asserted. If CTS is
not asserted during this time, the imager issues an error indication and discards the data. The imager
de-asserts RTS when transmission completes.

Software Handshaking
This parameter offers control of data transmission in addition to, or instead of, the control hardware
handshaking offers. There are five options.
If software handshaking and hardware handshaking are both enabled, Hardware Handshaking takes
precedence.
• None: Data transmits immediately. No response is expected from host.
• ACK/NAK: After transmitting data, the imager expects either an ACK or NAK response from the host.
When the imager receives a NAK, it transmits the same data again and waits for either an ACK or NAK.
After three unsuccessful attempts to send data when NAKs are received, the imager issues an error
indication and discards the data.
The imager waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK. If
the imager does not receive a response in this time, it issues an error indication and discards the data.
There are no retries when a time-out occurs.
• ENQ: The imager waits for an ENQ character from the host before transmitting data. If the imager does
not receive an ENQ within the Host Serial Response Time-out, it issues an error indication and discards
the data. The host must transmit an ENQ character at least every Host Serial Response Time-out to
prevent transmission errors.
• ACK/NAK with ENQ: This combines the two previous options. For re-transmissions of data due to a
NAK from the host, an additional ENQ is not required.
• XON/XOFF: An XOFF character turns the imager transmission off until the imager receives an XON
character. There are two situations for XON/XOFF:
• The imager receives an XOFF before it has data to send. When the imager has data to send, it waits
up to the Host Serial Response Time-out for an XON character before transmission. If it does not
receive an XON within this time, the imager issues an error indication and discards the data.
• The imager receives an XOFF during a transmission. Data transmission then stops after sending the
current byte. When the imager receives an XON character, it sends the rest of the data message. The
imager waits indefinitely for the XON.

CHAPTER 10 USB INTERFACE
Introduction
This chapter describes how to set up the imager with a USB host. The imager connects directly to a USB host,
or a powered USB hub, which powers it. No additional power supply is required.
Throughout the programming bar code menus, asterisks (*) indicate default values.
* Indicates Default
NOTE
*North American Standard USB Keyboard
Feature/Option
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.

USB Device Type
Select the desired USB device type.
NOTE
When changing USB Device Types, the imager automatically resets. The imager issues the standard
startup beep sequences.
NOTE
Before selecting USB CDC Host, install the CDC INF file on the host to ensure the imager does not stall
during power up (due to a failure to enumerate USB). If the imager stalls, to recover it:
1) Install the CDC INF file
or
2) After power-up, hold the trigger for 10 seconds, which allows the imager to power up using an
alternate USB configuration. Upon power-up, scan another USB Device Type.
NOTE
The SSI over USB CDC option enables a subset of the SSI protocol over the USB CDC interface which
omits all hardware handshaking functionality. For more information refer to the SSI Programmer's Guide.

USB Ignore Unknown Characters
This option applies only to the HID Keyboard Emulation device and IBM device. Unknown characters are
characters the host does not recognize. Select Send Bar Codes With Unknown Characters to send all bar
code data except for unknown characters. No error beeps sound. When Do Not Send Bar Codes With
Unknown Characters is selected, for IBM devices, bar codes containing at least one unknown character are
not sent to the host, and an error beep sounds. For HID Keyboard Emulation devices, the bar code characters
up to the unknown character are sent, and an error beep sounds.
*Send Bar Codes with Unknown Characters

Emulate Keypad
Enable this to send all characters as ASCII sequences over the numeric keypad. For example ASCII A is sent
as “ALT make” 0 6 5 “ALT Break”. This allows support for other country variants.
*Disable Keypad Emulation
Enable Keypad Emulation
10 - 10 DS457 Fixed Mount Imager Integration Guide
Emulate Keypad with Leading Zero
Enable this to send character sequences sent over the numeric keypad as ISO characters which have a
leading zero. For example ASCII A is sent as “ALT MAKE” 0 0 6 5 “ALT BREAK”.
*Disable Keypad Emulation with Leading Zero
Enable Keypad Emulation with Leading Zero
USB Keyboard FN1 Substitution
This option applies only to the USB HID Keyboard Emulation device. Enable this to replace any FN1
characters in an EAN 128 bar code with a Key Category and value (see FN1 Substitution Values on page 13-6
to set the Key Category and Key Value).
Enable FN1 Substitution
*Disable FN1 Substitution
USB Interface 10 - 11
Function Key Mapping
ASCII values under 32 are normally sent as control-key sequences (see Table 10-2 on page 10-13). Enable
this to send the keys in bold in place of the standard key mapping. Table entries that do not have a bold entry
remain the same whether or not this parameter is enabled.
*Disable Function Key Mapping
Enable Function Key Mapping

CHAPTER 11 OCR READING
Introduction
This chapter describes how to set up the imager for OCR reading. The DS457 can read 6 to 60 point OCR
typeface. It supports font types OCR-A, OCR-B, MICR-E13B, and US Currency Serial Number.
OCR is not as secure as a bar code. To decrease OCR misdecodes and speed OCR reading, set an accurate
OCR template and character subset, and use a check digit.
All OCR fonts are disabled by default. Enabling OCR can slow bar code decoding. Enabling more than one
OCR font could also slow OCR decoding and impact OCR decoding accuracy.
Throughout the programming bar code menus, asterisks (*) indicate default values.
* Indicates Default
NOTE
*Disable OCR-A
Feature/Option
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.

OCR Subset
Parameter # F1 AEh
Set an OCR subset to define a custom group of characters in place of a preset font variant. For example, if
scanning only numbers and the letters A, B, and C, create a subset of just these characters to speed decoding.
This applies a designated OCR Subset across all enabled OCR fonts.
To set or modify the OCR font subset, first enable the appropriate OCR font(s). Next, scan the following bar
code, then scan numbers and letters to form the OCR Subset from the Alphanumeric Keyboard from the
Advanced Data Formatting Programmer Guide. Then scan End of Message from the Advanced Data
Formatting Programmer Guide.
OCR Subset
To cancel an OCR subset, for OCR-A or OCR-B, scan OCR-A variant Full ASCII, or OCR-B variant Full ASCII.
For MICR E13B or US Currency Serial Number, create a subset which includes all allowed characters in that
character set, or scan an option from the Set Default Parameter on page 6-5 and re-program the imager.
OCR Quiet Zone
Parameter # F1h B7h
This option sets the OCR quiet zone. The DS457 stops scanning a field when it detects a sufficiently wide
blank space. The width of this space is defined by the End of Field option. Used with parsers that tolerate
slanted characters, the End of Field count is roughly a count of 8 for a character width. For example if set to 15,
then two character widths are an end of line indicator for the parser. Larger end of field numbers require bigger
quiet zones at each end of text line.
To set a quiet zone, scan the following bar code, then scan a two-digit number using the Numeric Keypad from
the Advanced Data Formatting Programmer Guide. The range of the quiet zone is 20 - 99 and the default is 50,
indicating a six character width quiet zone.

OCR Check Digit Modulus
Parameter # F1h B0h
This option sets OCR module check digit calculation. The check digit is the last digit (in the rightmost position)
in an OCR string and improves the accuracy of the collected data. The check digit is the end product of a
calculation made on the incoming data. For check digit calculation, for example Modulus 10, alpha and
numeric characters are assigned numeric weights (see OCR Check Digit Multiplier on page 11-26). The
calculation is applied to the character weights and the resulting check digit is added to the end of the data. If
the incoming data does not match the check digit, the data is considered corrupt.
The selected check digit option does not take effect until you set OCR Check Digit Validation.
To choose the Check Digit Modulus, such as 10 for modulo 10, scan the following bar code, then scan a
three-digit number from 001 to 099 representing the check digit using the Numeric Keypad from the Advanced
Data Formatting Programmer Guide. The default is 1.

CHAPTER 12 SYMBOLOGIES
Introduction
This chapter describes symbology features and provides the programming bar codes for selecting these
features. Before programming, follow the instructions in Chapter 1, Getting Started.
The imager is shipped with the settings shown in the Symbology Default Table on page 12-2 (also see
Appendix A, Standard Default Parameters for all host device 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 are shown in this chapter below the parameter title, and options are shown 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 the bar code can be seen clearly, and
bars and/or spaces are not merging.

Scanning Sequence Examples
In most cases, scanning one bar code sets the parameter value. For example, to transmit bar code data
without the UPC-A check digit, simply scan the Do Not Transmit UPC-A Check Digit bar code under Transmit
UPC-A Check Digit on page 12-16. The imager issues a fast warble beep and the LED turns green, signifying
a successful parameter entry.
Other parameters, such as Set Length(s) for D 2 of 5 require scanning several bar codes. See the individual
parameter, such as Set Length(s) for D 2 of 5, for this procedure.
Errors While Scanning
Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.
Symbology Parameter Defaults
Table 12-1 lists the defaults for all symbologies parameters. To change any option, scan the appropriate bar
code(s) provided in the Symbologies Parameters section beginning on page 12-8.

Decode UPC/EAN/JAN Supplementals
Parameter # 10h
Supplementals are bar codes appended according to specific format conventions (e.g., UPC A+2, UPC E+2,
EAN 13+2). The following options are available:
• If you select Ignore UPC/EAN with Supplementals, and the imager is presented with a UPC/EAN
plus supplemental symbol, the imager decodes UPC/EAN and ignores the supplemental characters.
• If you select Decode UPC/EAN with Supplementals, the imager only decodes UPC/EAN symbols with
supplemental characters, and ignores symbols without supplementals.
• If you select Autodiscriminate UPC/EAN Supplementals, the imager decodes UPC/EAN symbols with
supplemental characters immediately. If the symbol does not have a supplemental, the imager must
decode the bar code the number of times set via UPC/EAN/JAN Supplemental Redundancy on page
12-14 before transmitting its data to confirm that there is no supplemental.
• If you select one of the following Supplemental Mode options, the imager immediately transmits EAN-13
bar codes starting with that prefix that have supplemental characters. If the symbol does not have a
supplemental, the imager must decode the bar code the number of times set via UPC/EAN/JAN
Supplemental Redundancy on page 12-14 before transmitting its data to confirm that there is no
supplemental. The imager transmits UPC/EAN bar codes that do not have that prefix immediately.

Coupon Report
Parameter # F1h DAh
Traditional coupon symbols (old coupon symbols) are composed of two bar codes: UPC/EAN and Code128. A
new coupon symbol is composed of a single Databar Expanded bar code. The new coupon format offers more
options for purchase values (up to $999.99) and supports complex discount offers such as a second purchase
requirement.
An interim coupon symbol also exists that contains both types of bar codes: UPC/EAN and Databar Expanded.
This format accommodates both retailers that do not recognize or use the additional information included in the
new coupon symbol, as well as those who can process new coupon symbols.
Scan a bar code below to select one of the following options for decoding coupon symbols:
• Old Coupon Format - Scanning an old coupon symbol reports both the UPC and Code 128 portion of the
symbol if both are present in the field of view. The imager may report either the UPC or the Code 128 if
only one is within the field of view or is readable. UPC/EAN/JAN Supplemental Redundancy on page
12-14 controls the number of times the imager attempts to decode the entire symbol before transmission.
Additionally, scanning an interim coupon symbol reports UPC, and scanning a new coupon symbol
reports nothing (no decode).
• New Coupon Format - Scanning an old coupon symbol reports either UPC or Code 128, and scanning an
interim coupon symbol or a new coupon symbol reports Databar Expanded.
• Both Coupon Formats - Scanning an old coupon symbol reports both the UPC and Code 128 portion of

Code 39 Buffering (Scan & Store)
Parameter # 71h
This feature allows the imager to accumulate data from multiple Code 39 symbols.
Selecting the Scan and Store option (Buffer Code 39) temporarily buffers all Code 39 symbols having a leading
space as a first character for later transmission. The leading space is not buffered.
Decode of a valid Code 39 symbol with no leading space causes transmission in sequence of all buffered data
in a first-in first-out format, plus transmission of the “triggering” symbol. See the following pages for further
details.
When the Do Not Buffer Code 39 option is selected, all decoded Code 39 symbols are transmitted
immediately without being stored in the buffer.
This feature affects Code 39 only. If selecting Buffer Code 39, we recommend configuring the imager to
decode Code 39 symbology only.
Buffer Code 39 (Enable)
(01h)
*Do Not Buffer Code 39 (Disable)
(00h)
While there is data in the transmission buffer, selecting Do Not Buffer Code 39 is not allowed. The buffer
holds 128 bytes of information.
To disable Code 39 buffering when there is data in the transmission buffer, first force the buffer transmission
(see Transmit Buffer on page 12-38) or clear the buffer.
Buffer Data
To buffer data, Code 39 buffering must be enabled and a Code 39 symbol must be read with a space
immediately following the start pattern.
• Unless the data overflows the transmission buffer, the imager issues a lo/hi beep to indicate successful
decode and buffering. (For overflow conditions, see Overfilling Transmission Buffer.)
• The imager adds the decoded data excluding the leading space to the transmission buffer.
• No transmission occurs.
12 - 38 DS457 Fixed Mount Imager Integration Guide
Clear Transmission Buffer
To clear the transmission buffer, scan the Clear Buffer bar code below, which contains only a start character, a
dash (minus), and a stop character.
• The imager issues a short hi/lo/hi beep.
• The imager erases the transmission buffer.
• No transmission occurs.
Clear Buffer
NOTE
The Clear Buffer contains only the dash (minus) character. In order to scan this command, be sure
Code 39 length is set to include length 1.
Transmit Buffer
There are two methods to transmit the Code 39 buffer.
1.
Scan the Transmit Buffer bar code below. Only a start character, a plus (+), and a stop character.
• The imager transmits and clears the buffer.
• The imager issues a Lo/Hi beep.
Transmit Buffer
2.
Scan a Code 39 bar code with a leading character other than a space.
• The imager appends new decode data to buffered data.
• The imager transmits and clears the buffer.
• The imager signals that the buffer was transmitted with a lo/hi beep.
• The imager transmits and clears the buffer.
NOTE
The Transmit Buffer contains only a plus (+) character. In order to scan this command, be sure Code 39
length is set to include length 1.
Symbologies 12 - 39
Overfilling Transmission Buffer
The Code 39 buffer holds 128 characters. If the symbol just read results in an overflow of the transmission
buffer:
• The imager indicates that the symbol was rejected by issuing three long, high beeps.
• No transmission occurs. The data in the buffer is not affected.
Attempt to Transmit an Empty Buffer
If the symbol just read was the Transmit Buffer symbol and the Code 39 buffer is empty:
• A short lo/hi/lo beep signals that the buffer is empty.
• No transmission occurs.
• The buffer remains empty.

Set Lengths for MSI
Parameter # L1 = 1Eh, L2 = 1Fh
The length of a code refers to the number of characters (i.e., human readable characters), including check
digit(s) the code contains. Set lengths for MSI to any length, one or two discrete lengths, or lengths within a
specific range.
• One Discrete Length - Select this option to decode only MSI symbols containing a selected length.
Select the length using the numeric bar codes in Appendix D, Numeric Bar Codes. For example, to
decode only MSI symbols with 14 characters, scan MSI - One Discrete Length, then scan 1 followed by
4. To correct an error or to change the selection, scan Cancel on page D-3.
• Two Discrete Lengths - Select this option to decode only MSI symbols containing either of two
selected lengths. Select lengths using the numeric bar codes in Appendix D, Numeric Bar Codes. For
example, to decode only MSI symbols containing either 2 or 14 characters, select MSI - Two Discrete
Lengths, then scan 0, 2, 1, and then 4. To correct an error or to change the selection, scan
Cancel on page D-3.
• Length Within Range - Select this option to decode a MSI symbol with a specific length range.
Select lengths using numeric bar codes in Appendix D, Numeric Bar Codes. For example, to decode
MSI symbols containing between 4 and 12 characters, first scan MSI - Length Within Range. Then
scan 0, 4, 1, and 2 (single digit numbers must always be preceded by a leading zero). To correct an
error or change the selection, scan Cancel on page D-3.
• Any Length - Scan this option to decode MSI symbols containing any number of characters within the
imager’s capability.

NOTE
Due to the construction of the MSI symbology, it is possible for a scan line covering only a portion of the
code to be interpreted as a complete scan, yielding less data than is encoded in the bar code. To prevent
this, select specific lengths (MSI - One Discrete Length - Two Discrete Lengths) for MSI applications.

Security Level
Parameter # 4Dh
The imager offers four levels of decode security for delta bar codes, which include the Code 128 family,
UPC/EAN, and Code 93. Select increasing levels of security for decreasing levels of bar code quality. There is
an inverse relationship between security and imager aggressiveness, so choose only that level of security
necessary for any given application.
• Security Level 0: This setting allows the imager to operate in its most aggressive state, while providing
sufficient security in decoding most “in-spec” bar codes.
• Security Level 1: Select this option if misdecodes occur. This default setting should eliminate most
misdecodes.
• Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3: If Security Level 2 was selected and misdecodes still occur, select this security level.
Be advised, selecting this option is an extreme measure against mis-decoding severely out of spec bar
codes. Selecting this level of security significantly impairs the decoding ability of the imager. If this level
of security is necessary, try to improve the quality of the bar codes.

Macro PDF is a special feature for concatenating multiple PDF symbols into one file. The imager can decode
symbols that are encoded with this feature, and can store more than 64 kb of decoded data stored in up to 50
Macro PDF symbols.
CAUTION
When printing, keep each Macro PDF sequence separate, as each sequence has unique identifiers.
Do not mix bar codes from several Macro PDF sequences, even if they encode the same data. When
scanning Macro PDF sequences, scan the entire Macro PDF sequence without interruption.

Macro PDF Transmit / Decode Mode Symbols
Parameter # BCh
Select one of the options below for handling Macro PDF decoding. In Buffer All Symbols the imager can handle
sets of up to 50 maximum-sized Macro PDF symbols. In all other modes there is no limit to the size of the
Macro PDF set.
• Buffer All Symbols / Transmit Macro PDF When Complete: This transmits all decode data from an
entire Macro PDF sequence only when the entire sequence is scanned and decoded. Use the beeper
and LED signals provided with the DS457 when using this mode to ensure proper user feedback.
If the decode data exceeds the limit of 50 symbols, there is no transmission because the entire sequence
was not scanned. Use the parameter Flush Macro Buffer on page 12-93 to purge the buffer.
• Transmit Any Symbol in Set / No Particular Order: This transmits data from each Macro PDF symbol
as decoded, regardless of the sequence (although some error handling is performed; see Table 12-2).
When selecting this mode, enable Transmit Macro PDF Control Header on page 12-92. Also use the
beeper and LED signals provided with the DS457 to ensure proper user feedback.
• Passthrough All Symbols: This transmits and decodes all Macro PDF symbols and performs no
processing. In this mode the host is responsible for detecting and parsing the Macro PDF sequences.
Use this mode when the imager’s BEEPER_ON signal is not used to drive a beeper (see Table 3-1 on
page 3-4). In the other modes, some Macro PDF scanning sequences provide audible feedback only, so
if BEEPER_ON is not used no user feedback is provided. In Table 12-2, all actions marked No
Tranmission provide no feedback unless the BEEPER_ON signal is used. By using Passthrough All
Symbols mode every user decode is transmitted to the host where the host software can provide the
appropriate feedback.

CHAPTER 13 MISCELLANEOUS OPTIONS
Introduction
This chapter includes commonly used bar codes to customize how data is transmitted to the host device.
The imager ships with the settings shown in the Miscellaneous Options Default Table on page 13-2 (also see
Appendix A, Standard Default Parameters for all host device and miscellaneous imager 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 are shown in this chapter below the parameter title, and options are shown 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 the bar code can be seen clearly, and
bars and/or spaces are not merging.
To return all features to default values, scan the Set Default Parameter on page 6-5. Throughout the
programming bar code menus, default values are indicated with asterisks (*).

Prefix/Suffix Values
Key Category Parameter # Prefix = 63h, Suffix1 = 62h, Suffix2 = 64h
Decimal Value Parameter # Prefix = 69h, Suffix1 = 68h, Suffix2 = 6Ah
A prefix and/or one or two suffixes can be appended to scan data for use in data editing. To set a value for a
prefix or suffix, scan the prefix or suffix bar code below, then scan a four-digit number (i.e., four bar codes from
Appendix D, 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.
See Table E-1 on page E-1 for the four-digit code values. To correct an error or change a selection, scan
Cancel on page D-3.
NOTE
When using the imager with an SSI or SNAPI host, only a key category value of 1 is valid. All other values
are ignored.
To send a Prefix or Suffix with bar code data, first enable the format in which they are sent by setting the

CHAPTER 14 DRIVER’S LICENSE SET UP
(DS457-DL)
Introduction
The DS457-DL imager is capable of parsing out information from standard US driver's licenses and certain
other American Association of Motor Vehicle Administrators (AAMVA) compliant ID cards. Parsing can be
achieved in one of two ways:
• Internally embedded algorithms - scanning bar codes activates algorithms internally embedded in the
imager to produce formatted data. Use the formatted data for age verification, credit card application
information, and more.
• Server based parsing algorithms - the imager recognizes the same ID cards but encrypts the content and
sends this to a host side application. The host side application uses Motorola's server based parsing
algorithms, provided as a .DLL, to produce formatted data.
This chapter describes how to program the DS457-DL imager to read and use the data contained in the 2D bar
codes on US driver's licenses and AAMVA compliant ID cards.
14 - 2 DS457 Fixed Mount Imager Integration Guide
Driver’s License Parsing
There are three options available for programming the imager:
• No driver's license parsing (default) - disables the feature.
• Embedded driver's license parsing - this does not require Motorola software (.DLL).
Scan the bar codes on the following pages in the order indicating the sequence of data fields that the
imager outputs. See Parsing Driver’s License Data Fields (Embedded Driver's License Parsing) on page
14-3 for more information.
As jurisdictional updates become available, Motorola updates a series of bar codes on the Motorola Web
site: http//www.motorola.com/enterprisemobility/support.
These bar codes contain embedded software. Scanning these in conjunction with the bar codes on
<Blue><Italic>page 14-4 download jurisdictional software updates to the imager. The updates reside in
the imager's Flash memory and apply when the imager is next used.
• Server based driver's license parsing - this requires Motorola software (.DLL).
The imager recognizes the same ID cards, encrypts the content, and sends it to a host side application
that can use Motorola's server based parsing algorithms. Download/install the software from the
Motorola Web site at: http//www.motorola.com/enterprisemobility/support.
When the Motorola .DLL installs on the host server along with a custom driver's license application, the
DS457 imager can read 2D bar codes on standard US driver's licenses and AAMVA compliant ID cards
to produce formatted data. Use this data for age verification, credit card application information, and
more.
The Motorola driver's license Software Developer Kit (SDK), available on the Motorola Web site at
http//www.motorola.com/enterprisemobility/support, provides scanner software, sample code, a demo
application, and Help to develop the application necessary to generate formatted driver's license
information.
As jurisdictional updates become available, Motorola updates the .DLL on the Motorola Web site.
Scan the appropriate bar code below to program the imager.

Parsing Driver’s License Data Fields (Embedded Driver's License Parsing)
To begin programming a parsing rule:
1.
Scan Begin New Driver’s License Parse Rule on page 14-4.
2.
Scan any of the field bar codes on the following pages, or Send Keystroke (Control Characters and
Keyboard Characters) on page 14-24 to complete the parsing rule.
3.
After entering the entire rule, scan Save Driver’s License Parse Rule on page 14-4 to save the rule.
NOTE
Only ONE driver’s license parsing rule may be stored in memory at any time. Saving a new rule replaces
the prior rule.
To abort the programming sequence at any time during programming, scan Quit Entering Driver’s License Rule
on page 14-4. Any previously saved rule is retained.
To erase a programmed saved rule, scan Erase Driver’s License Parse Rules on page 14-4.
Embedded Driver's License Parsing Criteria - Code Type
After specifying the fields and their order for the parsed driver's license, you can also apply standard ADF rules
to the parsed data using the Parsed Driver’s License criterion bar code in the Advanced Data Formatting
Programmer Guide.
NOTE
Only create standard ADF rules on parsed driver's license data when configured for Embedded Driver's
License Parsing.
See Embedded Driver's License Parsing ADF Example on page 14-21 for a sample ADF rule using this code
type criterion.

Driver’s License Parse Field Bar Codes (continued)
The parse fields currently supported begin below. Not all IDs present data in the same format. For example, some IDs may
have separate fields for first name, last name, and middle initial, and others may have a single field with the entire name.
In addition, some IDs may expire on the subject's birth date and the actual expiration date field may only indicate the year.
In order to present data in a consistent format, the following nine bar codes return data that may be calculated from the
actual data contained within the ID bar code.

GLOSSARY
A
Aperture. The opening in an optical system defined by a lens or baffle that establishes the field of view.
API. An interface by means of which one software component communicates with or controls another. Usually used to
refer to services provided by one software component to another, usually via software interrupts or function calls
Application Programming Interface. See API.
ASCII. American Standard Code for Information Interchange. A 7 bit-plus-parity code representing 128 letters,
numerals, punctuation marks and control characters. It is a standard data transmission code in the U.S.
Autodiscrimination. The ability of an interface controller to determine the code type of a scanned bar code. After this
determination is made, the information content is decoded.
B
Bar. The dark element in a printed bar code symbol.
Bar Code. A pattern of variable-width bars and spaces which represents numeric or alphanumeric data in
machine-readable form. The general format of a bar code 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. See Symbology.
Bar Code Density. The number of characters represented per unit of measurement (e.g., characters per inch).
Bar Height. The dimension of a bar measured perpendicular to the bar width.
Bar Width. Thickness of a bar measured from the edge closest to the symbol start character to the trailing edge of the
same bar.
Bit. Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of
data. The pattern of 0 and 1 values within the byte determines its meaning.
Glossary - 2
DS457 Fixed Mount Imager Integration Guide
Bits per Second (bps). Bits transmitted or received.
Boot or Boot-up. The process a computer goes through when it starts. During boot-up, the computer can run
self-diagnostic tests and configure hardware and software.
bps. See Bits Per Second.
Byte. On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a pattern to represent a specific
character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in
memory is used to store one ASCII character.
C
CDRH. Center for Devices and Radiological Health. A federal agency responsible for regulating laser product safety.
This agency specifies various laser operation classes based on power output during operation.
CDRH Class 1. This is the lowest power CDRH laser classification. This class is considered intrinsically safe, even if all
laser output were directed into the eye's pupil. There are no special operating procedures for this class.
CDRH Class 2. No additional software mechanisms are needed to conform to this limit. Laser operation in this class
poses no danger for unintentional direct human exposure.
Character. A pattern of bars and spaces which either directly represents data or indicates a control function, such as a
number, letter, punctuation mark, or communications control contained in a message.
Character Set. Those characters available for encoding in a particular bar code symbology.
Check Digit. A digit used to verify a correct symbol decode. The scanner inserts the decoded data into an arithmetic
formula and checks that the resulting number matches the encoded check digit. Check digits are required for UPC
but are optional for other symbologies. Using check digits decreases the chance of substitution errors when a
symbol is decoded.
Codabar. A discrete self-checking code with a character set consisting of digits 0 to 9 and six additional characters:
( - $ : / , +).
Code 128. A high density symbology which allows the controller to encode all 128 ASCII characters without adding extra
symbol elements.
Code 3 of 9 (Code 39). A versatile and widely used alphanumeric bar code symbology with a set of 43 character types,
including all uppercase letters, numerals from 0 to 9 and 7 special characters (- . / + % $ and space). The code name
is derived from the fact that 3 of 9 elements representing a character are wide, while the remaining 6 are narrow.
Code 93. An industrial symbology compatible with Code 39 but offering a full character ASCII set and a higher coding
density than Code 39.
Code Length. Number of data characters in a bar code between the start and stop characters, not including those
characters.
COM Port. Communication port; ports are identified by number, e.g., COM1, COM2.
Continuous Code. A bar code or symbol in which all spaces within the symbol are parts of characters. There are no
intercharacter gaps in a continuous code. The absence of gaps allows for greater information density.
Glossary - 3
D
Dead Zone. An area within a scanner's field of view, in which specular reflection may prevent a successful decode.
Decode. To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the content of the specific bar code
scanned.
Decode Algorithm. A decoding scheme that converts pulse widths into data representation of the letters or numbers
encoded within a bar code symbol.
Decryption. Decryption is the decoding and unscrambling of received encrypted data. Also see, Encryption and Key.
Depth of Field. The range between minimum and maximum distances at which a scanner can read a symbol with a
certain minimum element width.
Discrete 2 of 5. A binary bar code symbology representing each character by a group of five bars, two of which are
wide. The location of wide bars in the group determines which character is encoded; spaces are insignificant. Only
numeric characters (0 to 9) and START/STOP characters may be encoded.
Discrete Code. A bar code or symbol in which the spaces between characters (intercharacter gaps) are not part of the
code.
DRAM. Dynamic random access memory.
E
EAN. European Article Number. This European/International version of the UPC provides its own coding format and
symbology standards. Element dimensions are specified metrically. EAN is used primarily in retail.
Element. Generic term for a bar or space.
Encoded Area. Total linear dimension occupied by all characters of a code pattern, including start/stop characters and
data.
ENQ (RS-232). ENQ software handshaking is also supported for the data sent to the host.
ESD. Electro-Static Discharge
F
Flash Memory. Flash memory is responsible for storing the system firmware and is non-volatile. If the system power is
interrupted the data is not lost.
H
Hz. Hertz; A unit of frequency equal to one cycle per second.
Glossary - 4
DS457 Fixed Mount Imager Integration Guide
I
IEC. International Electrotechnical Commission. This international agency regulates laser safety by specifying various
laser operation classes based on power output during operation.
Intercharacter Gap. The space between two adjacent bar code characters in a discrete code.
Interleaved 2 of 5. A binary bar code symbology representing character pairs in groups of five bars and five
interleaved spaces. Interleaving provides for greater information density. The location of wide elements
(bar/spaces) within each group determines which characters are encoded. This continuous code type uses no
intercharacter spaces. Only numeric (0 to 9) and START/STOP characters may be encoded.
Interleaved Bar Code. A bar code in which characters are paired together, using bars to represent the first character
and the intervening spaces to represent the second.
I/O Ports. interface The connection between two devices, defined by common physical characteristics, signal
characteristics, and signal meanings. Types of interfaces include RS-232 and PCMCIA.
K
Key. A key is the specific code used by the algorithm to encrypt or decrypt the data. Also see, Encryption and
Decrypting.
L
LASER. Light Amplification by Stimulated Emission of Radiation.The laser is an intense light source. Light from a laser
is all the same frequency, unlike the output of an incandescent bulb. Laser light is typically coherent and has a high
energy density.
Laser Diode. A gallium-arsenide semiconductor type of laser connected to a power source to generate a laser beam.
This laser type is a compact source of coherent light.
LED Indicator. A semiconductor diode (LED - Light Emitting Diode). The semiconductor uses applied voltage to
produce light of a certain frequency determined by the semiconductor's particular chemical composition.
Light Emitting Diode. See LED.
M
MIL. 1 mil = 1 thousandth of an inch.
Misread (Misdecode). A condition which occurs when the data output of a reader or interface controller does not agree
with the data encoded within a bar code symbol.
Glossary - 5
N
Nominal. The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and
negative deviations from this value.
Nominal Size. Standard size for a bar code symbol. Most UPC/EAN codes are used over a range of magnifications
(e.g., from 0.80 to 2.00 of nominal).
NVM. Non-Volatile Memory.
O
Open System Authentication. Open System authentication is a null authentication algorithm.
P
Parameter. A variable that can have different values assigned to it.
Percent Decode. The average probability that a single scan of a bar code would result in a successful decode. In a
well-designed bar code scanning system, that probability should approach near 100%.
Print Contrast Signal (PCS). Measurement of the contrast (brightness difference) between the bars and spaces of a
symbol. A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL
is the reflectance factor of the background and RD the reflectance factor of the dark bars.
Programming Mode. The state in which a scanner is configured for parameter values. See Scanning Mode.
Q
