Barcode Input

DataWedge 7.0

Overview

Barcode Input options specify the device hardware to use for scanning and the decoders to be applied on the acquired data before sending it for processing. Decoders included with DataWedge are explained below. DataWedge also provides audio and other feedback to alert the user of scanning results and barcode type. See the Scanner Parameters section for more information.

If using SimulScan, see SimulScan Input profile guide.

Barcode Input is used to specify:

  • Device cameras
  • 1D and 2D and imagers
  • Laser-based barcode scanners
  • Bluetooth-connected scanners
  • USB synchronous serial interface (SSI) scanners

Barcode Scanner Input reads data from the integrated barcode scanner built into the device, or attached via cable or Bluetooth connection, or implemented as a snap-on module. DataWedge supports lasers, imagers and internal cameras. The raw barcode data that's acquired is processed or formatted as using the Basic and Advanced Data Formatting Processing options that are found near the Output options.

Note: When SimulScan is used, DataWedge concatenates all captured text into a single string, and performs processing on the concatenated string. See the SimulScan section for details.

The parameters of this feature can be configured using the Set Config API.

Scanner Selection

For Barcode Input, the Scanner selection panel determines which scanning device will be used for data capture. The list of available scanners is based on devices present in (or connected to) the unit being configured.

The "Auto" option automatically determines the best scanning device from the list of available devices based on the rules below.

Auto Scanner Selection Rules:

  • If a Zebra Scan Module or Scan/MSR Module is installed, the 2D imager is selected.
  • If no Scan Module is installed, the camera is selected.
  • When the camera is selected, scanning is performed with the rear-facing camera.
  • When 2D Imager is selected, scanning is performed using the installed Scan or Scan/MSR module.

Bluetooth Scanners

DataWedge supports the following Zebra Bluetooth scanners:

  • RS507 Cordless Ring Scanner
  • RS6000 Ring Scanner
  • DS3678 Ultra-Rugged Scanner
  • LI3678 Ultra-Rugged Laser Scanner
  • DS2278 Bluetooth Scanner

Bluetooth scanners are supported according to the following rules:

  • To initially configure the RS507 in a Profile, the scanner must be paired and connected.
  • After initial configuration, a Bluetooth scanner can be enabled and disabled in the Profile, even if it is disconnected from the device. However, to configure decoders, reader parameters and other scanner settings, a Bluetooth scanner must be connected.
  • DataWedge does not automatically reconnect to a Bluetooth scanner if that scanner is connected while DataWedge is using a different auto-selected scanner. To re-enable a Bluetooth scanner, connect the scanner and select it in the Profile or re-choose the "Auto" selection option.
  • Auto-selection and Battery Swap - If Scanner selection is set to Auto and an RS507 was enabled prior to a battery swap, DataWedge continues working with that RS507 scanner upon reconnection after a battery is swapped. If the RS507 does not reconnect after the swap, DataWedge reverts to the current default scanner.
  • Keep Enabled on Suspend - This mode is supported on Bluetooth and pluggable scanners, and might result in faster battery drain than would otherwise be expected while in suspend mode. Note: The Zebra computing device wakes from suspend mode when pressing the scan trigger of any supported scanner.

USB SSI Scanners

DataWedge supports the following Zebra USB SSI scanners:

  • DS3608 USB SSI Scanner
  • LI3608 Ultra-Rugged USB SSI Laser Scanner

Support notes:

  • The DS3608 and LI3608 scanners are supported only on VC80 devices running Android.
  • Scanners must be configured using SSI over USB CDC.
  • The scanner connects via USB port and cable.

Important: Support for decode parameters can vary depending on the scanning device selected. For device-specific support notes, please refer to the Integrator Guide that accompanied the unit.

Auto Switch to Default on Event

This feature configures DataWedge to select an external scanner as the default scanning device immediately upon connection and revert to a built-in scanner when the external scanner is disconnected. External scanners include those connecting by Bluetooth, serial cable or snap-on module. If enabled, SWITCH_SCANNER should not be used upon scanner connection/disconnection as it can cause unexpected behavior. Disabled by default. Available only when “Auto" is selected in the Scanner selection panel.

This feature is intended to help reduce scanning workflow interruptions when a Bluetooth scanner is introduced and/or it becomes disconnected by losing power or moving out of range.

For Bluetooth scanners, if the device was not previously paired, a pairing barcode is displayed prior to automatic connection.

"Auto switch to default on event" is available only when "Auto" is selected.

Available Options:

  • Disabled - No scanner switching occurs when an external scanner is connected or disconnected (default).
  • On connect - Selects the external scanner as the default scanning device immediately upon connection.
  • On disconnect - Reverts to a built-in scanner based on its position in an internally managed scanner list (which varies by host device). This is usually the scanner most recently used prior to the external connection (see notes below).
  • On connect/disconnect - Selects an external scanner as the default scanning device immediately upon connection. Upon disconnection, reverts to the scanner set as the default prior to the external connection.

Notes:

  • The system selects the default scanner based on the connection state and the scanner's position in an internally managed scanner list. If the newly connected scanner is lower in the scanner list than the one currently selected as the default scanner, the newly connected scanner becomes the default scanner.
  • On devices with only one built-in scanner or imager, "On disconnect" reverts to that built-in scanner or imager.

Global Scanner Configuration

Global scanner configuration allows users to specify a generic scanner configuration applicable for all supported scanners. Rather than specifying multiple individual configurations for each separate scanner within a given DataWedge profile, the global configuration setting is provided to configure multiple scanners in a single profile.

Global scanner configuration displays all scanner parameters and values for each and every scanner even if not supported by a specific scanner. Since this list is all-inclusive, there is a possibility a particular parameter or value may not be supported on an individual scanner. In this case, an error is logged in logcat during scanning.

When global scanner configuration is enabled, access is still available to settings specific to individual scanners, such as the option “Keep enabled on suspend” (which specifically applies to Bluetooth and other peripheral scanners), even if the default scanner is selected as an internal scanner for “Scanner Selection” (See Figure 1). When applying configurations, if any of the global settings are not applicable to the specific scanner, those settings cannot apply and will be disregarded.

When a global setting is configured and then an individual scanner is configured, both configuration options are saved. The configurations will be applied in the following order:

  1. The global configuration is applied.
  2. The specific scanner configuration is applied.

If reports are generated when the global scanner configuration is set, the values supported by the connected device will be returned.

Configuration

Open a profile in DataWedge. The "Barcode input" section contains the option "Configure scanner settings".
Note: The “Configure scanner settings” option is still accessible even when the selected scanner in “Scanner Selection” is disconnected. In previous DataWedge versions prior to 6.8, all the scanner parameters (decoders, decoder params, etc.) are grayed-out and inaccessible.

img Figure 1. Profile settings

Tap "Configure scanner settings". A list of scanner configuration settings appears.

img Figure 2. Scanner configuration

Tap "Select scanner to set parameters". All Scanners option is available to allow the scanner settings to apply to all scanners.

img Figure 3. Global scanner configuration

Select All Scanners. A confirmation message appears indicating that any setting changes moving forward will be applicable to all scanners as a common global configuration. Any existing individual scanner setting will be replaced by this global setting. The scanner does not need to be connected to the device in order to configure the settings in the global scanner configuration.

Using Intents

Set the global scanner configuration by setting the value of parameter configure_all_scanners to "true" via SET_CONFIG intent API.

Decoder Selection

Many input methods include parameters that are configurable according to the expected scan targets and/or preferences of an organization. Enabling a narrow selection of decoders can help increase security, reduce decode errors and improve scan performance. For example, a company that routinely receives packages encoded with Code 128 symbology might consider limiting the Code 128 decoders it implements to those of the non-EAN variety.

Parameters for individual Decoders are modified within a Profile. Each DataWedge Profile can be assigned a unique group of Decoders and Decoder parameters (where applicable) to use with its associated application(s). This guide covers the selection of Decoders and provides details for those with configurable parameters.

Default Decoders

DataWedge decodes all major barcode symbologies. Popular formats are enabled by default in all DataWedge Profiles (indicated by an *). To improve scanning performance, Zebra recommends disabling all Decoders not required by the app(s) associated with a given Profile.

Note: Decoders lacking configurable parameters do not appear in the Decoder Parameters section. Others are linked to their corresponding parameter descriptions.

  • Concat Mode Always - There must be two ISBT codes in order to decode and perform concatenation. Does not decode single ISBT symbols.

  • Concat Mode Auto - Decodes and concatenates pairs of ISBT codes immediately. If only a single ISBT symbol is present, the device must decode the symbol the number of times set via Redundancy - Code128 before transmitting its data to confirm that there is no additional ISBT symbol.

Check ISBT Table - The ISBT specification includes a table that lists several types of ISBT barcodes that are commonly used in pairs. If ISBT128 Concat Mode is set, enable "Check ISBT Table" to concatenate only those pairs found in this table. Other types of ISBT codes are not concatenated.

Security Level - The scanner offers four levels of decode security for Code 128 barcodes. As the quality of barcodes decreases, implementing an increased level of security will compensate and help improve decoding success. There is an inverse relationship between scanner aggressiveness and security. Zebra recommends choosing carefully the level of security necessary for any given application:

  • Security Level 0 - This setting allows the scanner to operate in its most aggressive state, while providing sufficient security in decoding most "in-spec" barcodes.

  • Security Level 1 - This setting eliminates most decode failures.

  • Security Level 2 - Select this option if Security level 1 fails to eliminate decode failures.

  • Security Level 3 - If Security Level 2 is selected and decode failures still occur, select this security level. Be advised, selecting this option is an extreme measure against mis-decoding severely out-of-spec barcodes. Selecting this security level significantly impairs the decoding ability of the scanner. If this level of security is required, try to improve the quality of the barcodes.

Decode Lengths

The allowable decode lengths are specified by Length1 and Length2 as follows:

  • Variable length - Decode symbols containing any number of characters:
    • Set both Length1 and Length2 to "0" (zero)
  • Range - Decode a symbol with a specific length range from a-b:
    • Set Length1 to "a" (the lower bound) and set Length2 to "b" (the upper bound)
  • Two Discrete Lengths - Decode only symbols containing either of two specific lengths:
    • Set Length2 as the shorter length and Length1 as the longer one
  • One Discrete Length - Decode only symbols containing a specific length:
    • Set both Length1 and Length2 to the desired (non-zero) length

UPC/EAN Params

The UPC/EAN Parameter allows configuration of parameters that apply to more than one UPC or EAN decoder.


Security Level - The scanner offers four levels of decode security for UPC/EAN barcodes. As the quality of barcodes decreases, implementing an increased level of security will compensate and help improve decoding success. There is an inverse relationship between scanner aggressiveness and security. Zebra recommends choosing carefully the level of security necessary for any given application:

  • Level 0 - This setting allows the scanner to operate fastest, while providing sufficient security in decoding "in-spec" UPC/EAN barcodes.

  • Level 1 - As barcode quality levels diminish, certain characters become prone to decode failures before others (i.e., 1, 2, 7, 8). If the scanner is decode failures poorly printed barcodes, and the decode failures are limited to these characters, select this security level.

  • Level 2 - If the scanner fails to decode poorly printed barcodes, and the decode failures are not limited to characters 1, 2, 7, and 8, select this security level.

  • Level 3 - If the scanner is still fails to decode, select this security level. Be advised, selecting this option is an extreme measure against decode failures for severely out-of-spec barcodes. Selecting this level of security can significantly impair the decoding ability of the scanner. If this level of security is required, try to improve the quality of the barcodes.

Supplemental2 - A check in the checkbox enables this option.

Supplemental5 - A check in the checkbox enables this option.

Supplemental Mode

No Supplementals - The scanner is presented with a UPC/EAN plus supplemental symbol, the scanner decodes UPC/EAN and ignores the supplemental characters.

Supplemental Always - The scanner decodes only UPC/EAN symbols with supplemental characters, and ignores symbols without supplementals.

Supplemental Auto - The scanner decodes UPC/EAN symbols with supplemental characters immediately. If the symbol does not have a supplemental, the scanner must decode the barcode the number of times set via UPC/EAN Supplemental Redundancy before transmitting its data to confirm that there is no supplemental.

Supplemental Smart - Enables smart supplementals. In this mode, the decoder returns the decoded value of the main block immediately unless it belongs to one of the following supplemental types:

  • 378
  • 379
  • 977
  • 978
  • 979
  • 414
  • 419
  • 434
  • 439

If the barcode is preceded by one of the prefixes above, the image is searched more aggressively for a supplemental and attempts to scan it. If the supplemental scanning fails, only the main barcode is returned.

Supplemental 378-379 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with 378 or 379. Disables reading of supplementals for any other UPC/EAN barcode not starting with 378 or 379. Tries to scan the supplemental if present. If the supplemental scanning fails, only the main barcode is returned.

Supplemental 978-979 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with 978 or 979. Disables reading of supplementals for another UPC/EAN barcode not starting with 978 or 979. Tries to scan the supplemental if present. If the supplemental scanning fails, only then the main barcode is returned.

Supplemental 414-419-434-439 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with 414, 419, 434 or 439. Disables reading of supplementals for another UPC/EAN barcode not starting with 414, 419, 434 or 439. Tries to scan the supplemental if present. If the supplemental scanning fails, only the main barcode is returned.

Supplemental 977 - Enables (auto-discriminate) supplemental for UPC/EAN codes starting with 977. Disables reading of supplementals for another UPC/EAN barcode not starting with 977. Tries to scan the supplemental if present. If the supplemental scanning fails, only the main barcode is returned.

Retry Count - Retry count for auto-discriminating for supplementals. Possible values are 2 to 20. Note that this flag is only considered if Supplemental Mode is set to one of the following values: Supplementals Auto, Supplementals Smart, Supplementals 378-379, Supplementals 978-979, Supplementals 977 or Supplementals 414-419-434-439 (2 to 20).

Random Check Digit - Enables random weight check digit verification.

Linear Decode - Not in use. Deprecated.

Coupon - Enables Coupon code decoding. To successfully decode any Coupon codes, all appropriate decoders must be enabled.

Bookland - When enabled, select a Bookland Format from the list below.

Bookland Format - When Bookland is enabled, permits selection of an option for Bookland data:

  • Format ISBN-10 - The scanner reports Bookland data starting with 978 in traditional 10-digit format with the special Bookland check digit for backward-compatibility. Data starting with 979 is not considered Bookland in this mode.

  • Format ISBN-13 - The scanner reports Bookland data (starting with either 978 or 979) as EAN-13 in 13-digit format to meet the 2007 ISBN-13 protocol.

  • Convert GS1 To UPC EAN - If this is set it converts GS1 barcodes to UPC/EAN format. For this setting to work UPC/EAN symbologies must be enabled. A check in the checkbox indicates that the option is enabled.

Reader Params

Reader Parameters control specific configuration options for the barcode reader selected in the Profile being edited. Not all parameters will apply to all readers.


Illumination mode - Turns illumination on and off.

Illumination Brightness - Adjusts the brightness for the scanning session. Integer values: 0 - 10.

  • Low (0) - Low intensity illumination during scanning session.
  • High (10) - Maximum intensity illumination during scanning session (default).

Aim Mode - Turns aim pattern on and off.

Aim Type - Permits selection of reader behavior when the trigger is pressed:

  • Trigger - For each trigger press, a single barcode can be scanned.

  • Timed Hold – Once trigger is pressed, an aiming session is started for a time specified by Aim Timer. When this time expires, a decode session is started and scan beam will be visible. The decode session will remain active until the Beam Timer expires, the trigger is released or a barcode is decoded.

  • Timed Release - Once the trigger is pressed, an aiming session is started and will continue until the trigger is released. If the Aim Timer is expired when the trigger is released, a decode session will be started with scan beam visible for a remaining time equal to Beam Timer or a barcode is decoded.

  • Press and Release - The scan beam starts when the trigger is pressed and released. The decode session will remain active until the Beam Timer expires or a barcode is decoded.

  • Continuous Read - A press and hold of the scan trigger will continuously scan barcodes. Not supported with the Zebra RS507 Bluetooth Ring Scanner.

  • Press and Sustain - Starts the scan beam when the trigger is pressed and continues the decode session until the Beam Timer is expired, barcode is decoded or read is canceled. Scan beam is not stopped when the trigger is released. This avoids unexpected cancellations of a read by subsequently pressing the trigger button of the device; subsequent trigger presses while the beam is ON have no effect. Applies to internal imager on TC20/TC25 and RS6000/RS507 Bluetooth scanners connected to TC57/TC77 and PS20 devices.

Beam Timer - Sets the maximum amount of time (in ms) that the reader remains on. Supports a range from 0 - 60,000 ms in increments of 100 ms. A value of 0 sets the reader to stay on indefinitely.

Aim Timer - Sets the duration (in ms) for timed aim modes. Supports a range from 0 - 60,000 ms in increments of 100 ms.

Image Capture Mode - Sets the barcode scanner to image capture mode:

  • None - No image capturing.

  • Single Image Capture on Decode - Captures an image with decoded data.

  • Image Capture Only - Only captures and image and no barcode data will be dispatched.

Note: Zebra does not recommend changing the Image Capture Mode parameter when DataWedge is used to scan barcodes; DataWedge does not process image data.

Linear Security Level - Sets the number of times a barcode is read to confirm an accurate decode:

  • Security Redundancy and Length - Two times read redundancy based on redundancy flags and code length.

  • Security Short or Codabar - Two times read redundancy if short barcode or Codabar.

  • Security All Twice - Two times read redundancy for all barcodes.

  • Security Long and Short - Two times read redundancy for long barcodes, three times for short barcodes.

  • Security All Thrice - Three times read redundancy for all barcodes.

Picklist - Permits selection of Picklist mode, which instructs the imager to decode only the barcode directly under the cross-hair/reticle in the viewfinder. This feature is most useful for applications in which multiple barcodes may appear in the field of view during a decode session but only one is desired for decoding.

  • Disable - Disables Picklist mode; any barcode within the field of view can be decoded.

  • Hardware Picklist - Picklist mode is enabled by sending a command to hardware.

  • Software Picklist - Picklist feature is handled in the software; no commands are sent to hardware.

Picklist Notes

  • Performance might vary on some devices if Hardware or Software Picklist modes are set.
  • If using Multi-barcode mode, see important behavior notes below.

Same Symbol Timeout - Used to prevent the scanner from decoding the same symbol within a specified time interval (applicable only when Aim Type is set to Continuous Read). A value of 0 indicates that no interval is required between two successive reads.

Different Symbol Timeout - Used to prevent the scanner from decoding another symbol within a specified time interval (applicable only when Aim Type is set to Continuous Read). A value of 0 indicates that no interval is required between two successive reads.

Digimarc Decoding - Used to enable/disable support for Digimarc, which encodes and invisibly integrates traditional barcode data onto product packaging. Supported with internal imager only. Enabled by default. More about Digimarc.

Scanning Modes - Used to select between Single (normal), UDI and Multi-barcode modes. UDI mode acquires multiple simultaneous inputs as specified in the selected Universal Device Identifier UDI parameter(s). Multi-barcode mode acquires from 2-10 barcodes with each scan as specified in the Multi-barcode params panel. Default=5.

Keep Pairing Info After Reboot - Enable/disable automatic re-connection to the connected Bluetooth scanner after device reboot. Applies only to connected Bluetooth scanners.

See important notes below.

UDI Decoding

The Universal Device Identifier (UDI) parameter acquires multiple barcodes simultaneously.

This feature is supported using the imager on the following devices only:

  • TC51
  • TC56
  • TC70x
  • TC75x

Tap Scanning Modes to enable UDI decoding:

When UDI scanning mode is enabled (as above)... ...the selected UDI input parameter(s) will be used.

UDI Decoding Notes

  • UDI decoding is supported only on the devices listed above.
  • Output of collected UDI data might require settings adjustments of the token-separation character and/or output order. See the Keystroke Output guide guide for more information.
  • UDI settings can vary by geographic region. See the relevant sections of Keystroke Output, Intent Output and/or IP Output guides for more information.

Multi-barcode Decoding

When Multi-barcode scanning mode is enabled (as above)... ...specify the number of barcodes to be decoded with each scan.

Multi-barcode Notes

  • Supported with internal imager on TC20/TC25 devices only.
  • Acquired data from all barcodes is delivered as a single string when output as keystrokes. To add separators and adjust output order, see the Keystroke Output guide.
  • Picklist behavior - If the Picklist parameter is set to “Disabled,” the device will attempt to scan the number of barcodes (from 2-10) specified in the Multi-barcode params panel. If the Picklist parameter is set to a value other than “Disabled," the user is expected to move the cross-hair to each barcode to be scanned. Data is returned only after the specified number of barcodes is read.
  • Duplicate barcodes - If a label to be scanned contains multiple barcodes, some of which are duplicates (with the same label type and data), only one barcode from the duplicates is decoded; the remainder are ignored. If the label has two duplicate barcodes plus another two different barcodes, a maximum of three barcodes will be decoded from that form; one will be ignored as a duplicate.
  • Multiple barcode types - Barcodes can be of multiple label types and still be acquired together. For example, if the specified quantity for a Multi-barcode scan is four, two barcodes can be label type Code 128 and the other two can be type Code 39.
  • Barcodes in view -If the specified number of barcodes is not initially in view of the scanner, the scanner will not decode any data. If the scanner's field of view contains a number of barcodes greater than the specified quantity, the scanner will randomly decode barcode(s) until the specified number is reached. For example, if the count is set to two and eight barcodes are in the field of view, the scanner will decode the first two barcodes it sees, returning the data in random order. Data is returned only after the specified number of barcodes is read.

LCD Mode - Used to Enable/Disable LCD Mode, which enhances the ability of the imager to read barcodes from LCD displays such as cellphones (applies to Scan Module only). Use of LCD mode might lead to performance degradation and a blinking reticle prior to decoding.

HW Engine Low Power Timeout - Time (in ms) of inactivity before scanner enters low-power mode.

Inverse 1D Mode - Permits option selection for inverse 1D barcode decoding:

  • Disabled - Disables decoding of inverse 1D symbologies.

  • Enabled - Enables decoding of inverse 1D symbologies only.

  • Auto - Automatically detects and decodes positive and inverse 1D symbologies.

1D Quiet Zone Level - Sets the effort at which the decoder will attempt to decode "marginless" barcodes:

  • Level 0 - The decoder will perform margin decoding as usual.

  • Level 1 - The decoder will perform more aggressively.

  • Level 2 - The decoder requires only one side end of barcode.

  • Level 3 - The decoder can decode anything.

Behavior of these levels will vary based on the marginless decoder selected. See the Reduced Quiet Zone table for behaviors.

Note: Higher marginless levels will increase decoding times and the risk of decoding errors. Zebra recommends enabling only the symbologies that require a higher marginless level and leaving all other symbologies at the default level of 1.

Poor Quality Decode Effort - Permits selection of enhancement modes for decoding barcodes of poor or degraded quality. Available options:

  • Effort Level 0 - Decoding performance on regular 1D and 2D barcodes is not affected.

  • Effort Level 1 - The scanner performance on regular 2-D barcodes is impacted while decoding performance on Tesco Thailand barcode and Suppository barcode is improved.

  • Effort Level 2 - same as Level 1.

  • Effort Level 3 - same as Level 1.

Note: Same performance from Effort Level 1 to Effort Level 3.

Viewfinder Mode - Permits selection of supported Viewfinder modes:

  • Viewfinder Enabled - Enables only the viewfinder.

  • Static Reticle - Enables the viewfinder and a red reticle (cross-hairs) in the center of the screen to aid in positioning the barcode for scanning. This parameter is supported only when the Camera is used for scanning.

Character Set Configuration

Provides options to make adjustments with the decoder character set. These options are:

  • Character Set Selection
  • Auto Character Set Preferred Order
  • Auto Character Set Failure Option

img

Character Set Selection - Converts the barcode data to the specified encoding type if different from the default encoding type, UTF-8. Other options are: Auto Character Set Selection, ISO-8859-1, Shift_JIS and GB18030.

img

  • Auto Character Set Selection (Best Effort) - Decodes data in the preference order of character sets specified in the "Auto Character Set Preferred Order" list. If the data cannot be decoded based on the character sets listed, "Auto Character Set Failure Option" takes into effect. See description for each respective option for more details.

Auto Character Set Preferred Order - If "Auto Character Set Selection (Best Effort)" is selected, decodes data in the specified preference order of listed character sets. This is useful in cases where data can be decoded from more than one character set. The first character set listed which can decode the data successfully is chosen to decode the data - any other character set located lower in the list is not considered, even if the data could be successfully decoded using that character set. If DataWedge cannot find a character set from the preferred list to decode the data successfully, the character set selected in "Auto Character Set Failure Option" is used to decode the data.

Both the preferred character set list and its preference order is configurable. The order is rearranged by dragging the “hamburger-like” icon of the character set into the desired position. To delete a character set, long press on the item and the “Delete” option appears. To add a new character set, tap the “hamburger” menu at top right corner - an option to add characters sets, such as UTF-8 and GB2312, will appear.

img

Auto Character Set Failure Option - Used to decode data if the device cannot successfully decode based on the character sets listed in the "Auto Character Set Preferred Order" list. If “None” is selected, “Null” is returned as the data string.

Scan Params

Scan Parameters allow for configuration of Code ID and scanner-specific decoding feedback options for the scanner selected in the Profile being edited.

Note: Some parameters are device-dependent.


Code ID Type - Permits the selection of a Code ID character to insert between the prefix and the decoded symbol. The Code ID character identifies the code type of a scanned barcode. This information can be useful to an application when multiple barcode types are being read. Available options:

  • Code ID Type None - Insert no prefix.

  • Code ID Type Aim - Inserts a standards-based three-character prefix.

  • Code ID Type Symbol - Inserts a Zebra-defined single-character prefix.

Connection Idle Time - Specifies the length of time (in seconds) for a peripheral Bluetooth scanner to remain connected until transitioning to standby mode to conserve battery power.

Volume Type - Permits selection of the volume setting to be used when playing the Decode Audio Feedback. Available options:

  • Ringer and Notifications - Uses Ringer and Notifications volume setting for audio feedback.

  • Music and Media - Uses Music and Media volume setting for audio feedback.

  • Alarms - Uses the Alarms volume setting for audio feedback.

  • Decode Audio Feedback - Select an audio tone to play to indicate a successful decode.

Note: Not all ringtones are supported as decode tones; some ringtones might be truncated when used as a decode tone. Zebra recommends testing all selected tones before deployment.

Decode Haptic Feedback - Enable the mobile computer to vibrate to indicate a successful decode.

Decode Feedback LED Timer - Defines the length of time (in ms) to flash the Green LED to indicate a successful decode.

Decoding LED Notification - When enabled, causes the Red LED to flash when the scan trigger is pressed.

Important: Support for decode parameters can vary depending on the scanning device selected. For device-specific support notes, please refer to the Integrator Guide that accompanied the unit.
