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.

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 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.

Trigger Jack Connector Pins

Figure 2-10

Location and Positioning

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.

Trigger Jack Connector Pins

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.

CAUTION Consult an opto-mechanical engineer to recommend an appropriate window material and to

determine if coatings are appropriate for the specific application.

Installation 2 - 11

NOTE 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

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 - 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.

Capturing Data

1D bar code symbol

2D bar code symbol

2D dot peen DPM symbol

0123 45

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.

Imaging 3 - 3

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.

Figure 3-3

Acceptable and Incorrect Aiming

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

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 Zebra

Global Customer 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 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 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.

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.

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.

User Preferences Parameter Defaults

Table 6-1 lists defaults for user preferences parameters. To change any parameter value, scan the appropriate

bar code(s) provided in the User Preferences section beginning on page 6-5.

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.

Use this feature to program a multicode expression for Multicode Mode (grid method). The default is 1, which indicates any bar code.

NOTE DS457-DP does not support this parameter.

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 - 26 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).

To decode the set of three bar codes while excluding the center Code 128 bar code, as in Figure 6-3, the expression is:

The expression in decimal is (formatted for readability):

3 C 2 0 15 R 4 0 0 50 50 ; C 2 [F0 24] R 4 70 0 100 40 ; C 2 0 8 R 4 65 60 100 100 ;

To program the expression via scanning parameters the sequence is:

[MultiCode-Expression] 03 C 02 00 0F R 04 00 00 32 32 ; C 02 F0 24 R 04 46 00 64 28 ; C 02 00 08 R 04 41 3C 64 64 ; [End Of Message]

To program the expression via host command (SSI/SNAPI) the sequence is:

0x03 0x43 0x02 0x00 0x0F 0x52 0x04 0x00 0x00 0x32 0x32 0x3B 0x43 0x02 0xF0 0x24 0x52 0x04 0x46 0x00 0x64 0x28 0x3B 0x43 0x02 0x00 0x08 0x52 0x04 0x41 0x3C 0x64 0x64 0x3B

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): 17 80 04 00 00 13 06 00 02 95 41 00 42 00 06 00 [Multicode Expression in Hex] FD A3

Response (from imager): 08 80 00 00 00 04 06 00 FF 6E

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

• Scanning each value of the expression produces a two-tone (same pitch) beep.

• Scanning the

•

Check the expression for syntax errors.

•

Try programming a simple expression to ensure the syntax is correct. See Examples of Simple Multicode

Expressions.

Multicode Expression bar code produces a two-tone (same pitch) beep.

End Of Message bar code produces a four-tone (high-low-high-low) beep.

•

Review Notes on page 6-26 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 6-24. 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.

Examples of Simple Multicode Expressions

The simplest multicode expression is:

•

One bar code of any type, anywhere in the image.

•

To program this use: [MultiCode-Expression] 01 ; [End Of Message]

Another simple multicode expression is:

•

One Code 128 bar code, anywhere in the image.

•

To program this use: [MultiCode-Expression] 01 C 02 00 08 ; [End Of Message]

Miscellaneous Parameters

Transmit Code ID Character

Parameter # 45 (SSI # 2Dh)

A Code ID character identifies the code type of a scanned bar code. This is useful when the imager is decoding more than one code type. In addition to any single character prefix already selected, the Code ID character is inserted between the prefix and the decoded symbol.

Select no Code ID character, a Symbol Code ID character, or an AIM Code ID character. For Code ID Characters, see Code Identifiers on page B-1.

Prefix/Suffix Values

Parameter # Prefix = 105, Suffix1 = 104, Suffix2 = 106

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

Scan Data Transmission Format on page 6-39.
