1 - 2 2020/4820/4820 i User’s GuideCordless System: Main ComponentsAbout the BatteryUse only the Li-ion battery packs provided by Hand Held Products. The use of any battery pack not sold by Hand Held Products will void your warranty and may result in damage to your unit.Power is supplied to the cordless image scanner by a rechargeable battery that is integrated in the image scanner handle. Each image scanner is shipped with a battery. (See Product Specifications beginning on page 13-1.)Charging InformationThe battery is designed to charge while the image scanner is positioned in the cordless base unit. Refer to "2020 LED Sequences and Meaning" on page 3-4 for an interpretation of the Charge Status indicators.• Place the image scanner in the base that is connected to an appropriate power supply.Battery Recommendations• Batteries are shipped approximately 30% to 60% charged and should be fully charged for maximum charge capacity.in HandleBattery ContainedImage Scanner2020Cordless Base!
2020/4820/4820 i User’s Guide 1 - 3• The battery is a lithium ion cell and can be used without a full charge, and can also be charged without fully discharging, without impacting the battery life. There is no need to perform any charge/discharge conditioning on this type of battery.• Do not disassemble the battery. There are no user-serviceable parts in the battery.• Keep the base connected to power when the host is not in use.• Replace a defective battery immediately since it could damage the image scanner.• Don’t short-circuit a battery or throw it into a fire. It can explode and cause severe personal injury.• Although your battery can be recharged many times, it will eventually be depleted. Replace it after the battery is unable to hold an adequate charge.• If you are not sure if the battery or charger is working properly, send it to Hand Held Products or an authorized Hand Held Products service center for inspection.Proper Disposal of the BatteryWhen the battery has reached the end of its useful life, the battery should be disposed of by a qualified recycler or hazardous materials handler. Do not incinerate the battery or dispose of the battery with general waste materials. You may send batteries to Hand Held Products (postage paid). The shipper is responsible for complying with all federal, state, and local laws and regulations related to the packing, labeling, manifesting, and shipping of spent batteries. Contact the Product Service Department (page 15-1) for recycling or disposal information. Since you may find that your cost of returning the batteries significant, it may be more cost effective to locate a local recycle/disposal company.Connecting the Base A base can be connected between the keyboard and PC as a “keyboard wedge,” plugged into the serial port, plugged into a USB port, or connected to a portable data terminal in wand emulation or non decoded output mode. Turn off power before connecting the base, then power up the computer once the base is fully connected. When the base is connected and powered up, put the image scanner in the base to establish a link. The green LED on the base flashes to indicate the image scanner’s battery is charging.

Once the image scanner is placed into the base, the software automatically links the image scanner and the base. If the image scanner and base have previously been linked, you do not receive any feedback. If this is the first time that the image scanner and base are linked, both devices emit a short chirp when their radios link. At this point, you are set to one image scanner to one base.1. Provide power to the base.2. Place the image scanner into the base. The image scanner and base link.3. To determine if your cordless system is set up correctly, scan one of the sample barcodes in the back of this manual. If the image scanner provides a single good read beep and the green LED lights, the image scanner has successfully linked to the base. If you receive a triple error beep and the red LED lights, the image scanner has not linked to the base. Refer to page 14-4 for troubleshooting information.Communication Between the Cordless System and the HostThe cordless image scanner provides immediate feedback in the form of a “good read” indication (a green LED on the image scanner and an audible beep) after a barcode is scanned correctly and the base has acknowledged receiving the data. This is possible since the cordless system provides two-way communication between the image scanner and the base. Image Scanner2020 Cordless BaseGreen LEDRed LED

1 - 10 2020/4820/4820 i User’s GuideReading TechniquesThe image scanner has a view finder that projects a bright green aiming beam that corresponds to the image scanner’s horizontal field of view. The aiming beam should be centered over the barcode, but it can be positioned in any direction for a good read.The aiming beam is smaller when the image scanner is closer to the code and larger when it is farther from the code. Symbologies with smaller bars or elements (mil size) should be read closer to the unit. Symbologies with larger bars or elements (mil size) should be read farther from the unit. To read single or multiple symbols (on a page or on an object), hold the image scanner at an appropriate distance from the target, pull the trigger, and center the aiming beam on the symbol. If the code being scanned is highly reflective (e.g., laminated), it may be necessary to tilt the code up 15° to 18° to prevent unwanted reflection.Linear barcode 2D Matrix symbol

2 - 18 2020/4820/4820 i User’s GuideHost ACK SelectionSome applications require that the host terminal (or server) approve or reject incoming barcode data and notify the operator of these actions. These applications require that the host maintain control over the response indicators emitted from the source image scanner. Turning the Host ACK selection on, configures the cordless system image scanners to respond to commands from the host system.The following criteria must be met for the Host ACK to work correctly:• The cordless system must be configured for Host Port RS-232 (terminal ID = 000) or USB COM Emulation (terminal ID = 130).• RTS/CTS is defaulted off. You must enable it if the host system requires it.• Host ACK must be enabled (page 2-19). • System performance degrades when using Host ACK at rates lower than 9600.• The host terminal software must be capable of interpreting the barcode data, make decisions based on the data content, and send out appropriate escape commands to the source image scanner.Escape commands are addressed to the source image scanner via “Application Work Groups.” Once a command is sent, all image scanners in a group respond to that command. Because of this situation, it is recommended that each image scanner is assigned to its own group in host ACK mode.The commands to which the image scanner responds are listed on page 2-20. The <ESC> is a 1B in hex. A typical command string is y <ESC> x, where “y” is the application work group number, “<ESC> x” is the escape command, and the comma is the terminator, which is required.Commands may be strung together to create custom response sequences. An example of a command string is listed below.0<ESC>4<ESC>5<ESC>6,The above example will make an image scanner in application work group zero beep low, medium, high.Once Host ACK is enabled, the system works as follows:• The image scanner reads a code and sends data to the base/host system. No audible or visual indication is emitted until the image scanner receives an escape command. The image scanner read illumination goes out upon a successful read.• Image Scanner operation is suspended until 1) a valid escape string is received from the host system (via the base) or 2) the image scanner “times out.”• Once condition 1 or 2 above has been met, the image scanner is ready to scan again, and the process repeats.Time out is indicated by three rapid beeps at the same pitch. A time out occurs if the source image scanner does not receive a valid escape command in 10 seconds. If a time out occurs, the operator should check the host system to understand why a response to the image scanner was not received.

2020/4820/4820 i User’s Guide 3 - 13Basic System OperationCordless BaseThe cordless base provides the link between the cordless image scanner and the host system. The base contains an interface assembly and an RF communication module. The RF communication module performs the data exchange between the cordless image scanner and the interface assembly. The control assembly coordinates the central interface activities including: transmitting/receiving commands and data to/from the host system, performing software activities (parameter menuing, visual indicator support, power-on diagnostics), and data translation required for the host system.The base also is the image scanner’s battery charger. Refer to "Base Charge Mode" on page 3-3 for additional information.RF (Radio Frequency) Module OperationThe cordless system uses a two-way Bluetooth radio to transmit and receive data between the image scanner and the base. Designed for point-to-point and multipoint-to-single point applications, the radio operates using a license free ISM band, which sends relatively small data packets at a fast data rate over a radio signal with randomly changing frequencies, makes the cordless system highly responsive to a wide variety of data collection applications and resistant to noisy RF environments. Bluetooth Class 2 power level provides a communication range of 33 feet (10m) between the image scanner and base/Bluetooth adapter, depending on the environment.Cordless Image ScannerThe cordless image scanner enables fast and accurate barcode scanning using a non-contact area image scanner. The image scanner is comprised of an area image engine, a decode/control assembly, and an RF communication module. The image engine performs the barcode image illumination and sensing. The decode/control assembly coordinates the central communication activities including: capturing and decoding the barcode image data, performing software activities (parameter menuing, visual indicator support, low battery indication), and data translation required for the host system. The RF communication module performs the data exchange between the image scanner and the base.
3 - 2 2020/4820/4820 i User’s GuideSystem ConditionsThe components of the cordless system interact in specific ways as you associate an image scanner to a base, as you move an image scanner out of range, bring an image scanner back in range, or swap image scanners between two cordless systems. The following information explains the cordless system operating conditions.Linking ProcessOnce an image scanner is placed into the base, the image scanner’s battery charge status is checked, and software automatically detects the image scanner and links it to the base depending on the selected link mode.Image Scanner Is Out of RangeThe cordless image scanner is in communication with its base, even when it is not transmitting barcode data. Whenever the image scanner can’t communicate with the base for a few seconds, it is out of range. If the image scanner is out of range and you scan a barcode, the image scanner issues a triple beep indicating no communication with the base. In addition, your image scanner and base can sound an alarm if programmed to emit an alarm. Refer to "Out-of-Range Alarm" on page 3-14.Image Scanner Is Moved Back Into RangeThe image scanner re-links if the image scanner or the base have been reset or the image scanner comes back into range. If the image scanner re-links, you will hear a single chirp when the re-linking process (uploading of the parameter table) is complete. Out of Range and Back into Range with Data Accumulation Mode OnThe image scanner may store a number of symbols (approximately 500 UPC symbols, others may vary) when out of range and then send them to the base when back in range. You will not hear a communication error beep in this mode, but you will hear a short buzz when you pull the trigger if the radio communication is not working. Once the radio connection is made, the image scanner produces a series of beeps while the data is being transferred to the base.
2020/4820/4820 i User’s Guide 3 - 3Base Charge ModeIn order for the battery to be charged, there must be enough voltage for the circuitry to work. There are three methods during which power can be supplied to the base:1: 9VDC power supply connected to the barrel connector2: 12VDC host power source only3: 5VDC host power source onlyThe chart below describes each selection by condition.Using a slow charge rate draws less current (power) from the input power source when the battery is mostly discharged.Note: If you attach the 4820/4820i system to a host with a 12V power source, the 12V host is dominant; the system pulls power from the host and not the 9V power supply. For example, if you have a host system with a 12 volt available to the base, it will supersede the 9V power supply.

3 - 6 2020/4820/4820 i User’s GuideLocked Link Mode - Single Image ScannerIf you link an image scanner to a base using the Locked Link Mode, other image scanners are blocked from being linked if they are inadvertently placed into the base. If you do place a different image scanner into the base, it will charge the image scanner, but the image scanner will not be linked. To use a different image scanner, you need to unlink the original image scanner by scanning the Unlink Image Scanner barcode. (See "Image Scanner Modes" on page 3-5.)Open Link Mode - Single Image ScannerWhen newly shipped or defaulted to factory settings, the base and image scanner are not linked. By placing an image scanner into the base, they establish a link. Placing a different image scanner into the base establishes a new link and the old image scanner is unlinked. Each time an image scanner is placed into the base, it becomes the linked image scanner; the old image scanner is unlinked.Override Locked Image ScannerIf you need to replace a broken or lost image scanner that is linked to a base, scan the Override Locked Image Scanner barcode below with a new image scanner and place that image scanner in the base. The locked link will be overridden; the broken or lost image scanner’s link with the base will be removed, and the new image scanner will be linked.* Locked Link Mode(Single Image Scanner)Open Link Mode(Single Image Scanner)Override Locked Image Scanner(Single Image Scanner)

3 - 8 2020/4820/4820 i User’s GuideImage Scanner NameYou may assign a name to each image scanner you are using. When you have multiple image scanners linked to one base, you may want to name each image scanner so you will be able to control the image scanner receiving imaging commands sent from the base.The default name for a 4820 is “4820,” and ”4820i” for a 4820i. If you have more than one image scanner linked to a base, and they all have the default names, the first image scanner linked to the base receives commands. You can change the name of an image scanner using a serial command (refer to "Image Scanner Name" on page 12-8) or using a barcode command. To change the name serially, unlink all except one of the image scanners from the base. Send “:4820:BT_NAMname.” or “:4820i:BT_NAMname.”, where name is the new image scanner name. If you wish to change the names of additional image scanners, re-link them one at a time and repeat the “:4820:BT_NAMname.” or “:4820i:BT_NAMname.” command for each image scanner.
2020/4820/4820 i User’s Guide 3 - 9To rename image scanners with sequential, numeric names, scan the barcodes below. Scan the Reset code after each name change and wait for the scanner to re-link to the base before scanning another barcode to rename the next image scanner.Alternatively, you may change the name with a barcode command if you cannot send serial commands to the base. One way to do this is to scan the barcode below and scan a number for the image scanner name. For example, if you had 7 image scanners to one base, scan the barcode below with the first image scanner, scan the 1 barcode on the Programming Chart inside the back cover of this manual and scan Save. Then scan the Reset barcode and wait for the scanner to re-link to the base before scanning the next barcode.

Scan the Reset barcode (page 3-9 or on the Programming Chart inside the back cover of this manual). You may use Barcode Builder, which is included with Quick*View. Refer to Quick*View on page 11-5 for instructions about downloading Quick*View from the Hand Held Products website: www.handheld.com.Image Scanner Report Scan the barcode below to generate a report for the connected image scanners. The report indicates the port, work group, image scanner name, and address.Application Work GroupsYour cordless system can have up to seven image scanners linked to one base. You can also have up to seven work groups. If you want to have all of the image scanners’ settings programmed alike, you don’t need to use more than one work group. If you want each image scanner to have unique settings (e.g., beeper volume, prefix/suffix, data formatter), then you may program each image scanner to its own unique work group and may program each image scanner independently. For example, you might want to have multiple work groups in a retail/warehouse application where you need to have different data appended to barcodes used in the warehouse area versus the retail area. You could assign all of the image scanners in the retail area to one work group and those in the warehouse to another. Consequently, any desired changes to either the retail or warehouse area would apply to all image scanners in that particular work group. Visual Xpress (page 11-4) makes it easy for you to program your system for use with multiple image scanners and multiple work groups.The image scanner keeps a copy of the menu settings it is using. Whenever the image scanner is connected or reconnected to a base, the image scanner is updated with the latest settings from the base for its work group. The image scanner also receives menu setting changes processed by the base. If an image scanner is removed from one base and placed into another base, it will be updated with the new base settings for whatever work group that the image scanner was previously assigned. For example, if the image scanner was in work group 1 linked to the first base, it will be placed in work group 1 in the second base with the associated settings.Image Scanner Report

When a different code is presented, the image scanner is triggered to read the new code. Note:The image scanner automatically adjusts the illumination LEDs to the lowest light level possible to maintain a good lock on the Scan Stand symbol. When a symbol is presented, the image scanner’s light levels adjust to the saved setting (see LED Power Level on page 4-9). This mode requires at least 50 lux of ambient light to operate correctly.Scan Stand SymbolWhen a unit is in Scan Stand mode, the LEDs shine at the Scan Stand symbol on the base of the stand which tells it to remain idle. When the Scan Stand symbol is covered, the image scanner turns the LEDs on at the configured power level (Default High) and attempts to find and decode barcodes in its field of view.Presentation ModeNote: This mode requires at least 50 lux of ambient light to operate correctly.Scanning the barcode below programs the image scanner to work in Presentation Mode. Presentation Mode uses ambient light to detect barcodes. The LEDs are off until a barcode is presented to the image scanner, then the LEDs turn on automatically to read the code.

2020/4820/4820 i User’s Guide 4 - 11CenteringUse Centering to narrow the image scanner’s field of view to make sure the image scanner reads only those barcodes intended by the user. For instance, if multiple codes are placed closely together, centering will insure that only the desired codes are read. (Centering can be used in conjunction with Aimer Delay, page 4-10, for the most error-free operation in applications where multiple codes are spaced closely together. Using the Aimer Delay and Centering features, the image scanner can emulate the operation of older systems, such as linear laser barcode image scanners.)In the example below, the gray area is the full image scanner field of view and the white area is the centering window. Barcode 1 will not be read, while Barcode 2 will be.The default centering window is a 128x96 pixel area in the center of the image scanner’s field of view.

The image scanner attempts to find and decode new symbols as long as the trigger is pulled. When this programming selection is turned Off, the image scanner will only read the symbol closest to the aiming beam.No ReadWith No Read turned On, the image scanner notifies you if a code cannot be read. If using a Quick*View Scan Data Window, an “NR” appears when a code cannot be read. If No Read is turned Off, the “NR” will not appear. Required On/Not Required *OffOn* OffOn* Off
4 - 18 2020/4820/4820 i User’s GuideIf you want a different notation than “NR,” for example, “Error,” or “Bad Code,” you can edit the output message using the Data Formatter (page 6-5). The hex code for the No Read symbol is 9C. Print WeightPrint Weight is used to adjust the way the image scanner reads Matrix symbols. If an image scanner will be seeing consistently heavily printed matrix symbols, then a print weight of 6 may improve the reading performance. For consistently light printing, a print weight of 2 may help. After scanning the Set Print Weight barcode, set the print weight (from 1-7) by scanning digits from the inside back cover, then scanning Save. Default = 4.Video ReverseVideo Reverse is used to allow the image scanner to read barcodes that are inverted. The “Off” barcode below is an example of this type of barcode. If additional menuing is required, Video Reverse must be disabled to read the menu barcodes and then re-enabled after menuing is completed.Note: Images downloaded from the unit will not be reversed. This is a setting for decoding only.Set Print Weight* DefaultOn* Off

2020/4820/4820 i User’s Guide 5 - 15Data EditingPrefix/Suffix OverviewWhen a barcode is scanned, additional information is sent to the host computer along with the barcode data. This group of barcode data and additional, user-defined data is called a “message string.” The selections in this section are used to build the user-defined data into the message string.Prefix and Suffix characters are data characters that can be sent before and after scanned data. You can specify if they should be sent with all symbologies, or only with specific symbologies. The following illustration shows the breakdown of a message string:Points to Keep In Mind• It is not necessary to build a message string. The selections in this chapter are only used if you wish to alter the default settings. Default prefix = None. Default suffix = None.• A prefix or suffix may be added or cleared from one symbology or all symbologies.• You can add any prefix or suffix from the Code Page Mapping of Printed Barcodes on page A-6, plus Code I.D. and AIM I.D.• You can string together several entries for several symbologies at one time.• Enter prefixes and suffixes in the order in which you want them to appear on the output.• When setting up for specific symbologies (as opposed to all symbologies), the specific symbology ID value counts as an added prefix or suffix character.To Add a Prefix or Suffix:Step 1. Scan the Add Prefix or Add Suffix symbol (page 5-4).Step 2.

2020/4820/4820 i User’s Guide 6 - 16Data FormattingData Format Editor IntroductionYou may use the Data Format Editor to change the image scanner’s output. For example, you can use the Data Format Editor to insert characters at certain points in barcode data as it is scanned. The selections in the following pages are used only if you wish to alter the output. Default Data Format setting = None.Normally, when you scan a barcode, it gets outputted automatically; however when you do a format, you must use a “send” command (see Send Commands on page 6-2) within the format program to output data.Multiple formats may be programmed into the image scanner. They are stacked in the order in which they are entered. However, the following list presents the order in which formats are applied:1. Specific Term ID, Actual Code ID, Actual Length2. Specific Term ID, Actual Code ID, Universal Length3. Specific Term ID, Universal Code ID, Actual Length4. Specific Term ID, Universal Code ID, Universal Length5. Universal Term ID, Actual Code ID, Actual Length6. Universal Term ID, Actual Code ID, Universal Length7. Universal Term ID, Universal Code ID, Actual Length8. Universal Term ID, Universal Code ID, Universal LengthIf you have changed data format settings, and wish to clear all formats and return to the factory defaults, scan the Default Data Format code on page 6-4.To Add a Data FormatStep 1. Scan the Enter Data Format symbol (page 6-4).Step 2. Primary/Alternate FormatDetermine if this will be your primary data format, or one of 3 alternate formats. (Alternate formats allow you “single shot” capability to scan one barcode using a different data format. After the one barcode has been read, the image scanner reverts to the primary data format. See page 6-5.) If you are programming the primary format, scan 0 using the Programming Chart inside the back cover of this manual. If you are programming an alternate format, scan 1, 2, or 3, depending on the alternate format you are programming.Step 3. Terminal TypeRefer to Supported Terminals (page 2-8) and locate the Terminal ID number for your PC. Scan three numeric barcodes on the inside back cover to program the image scanner for your terminal ID (you must enter 3 digits). For example, scan 0 0 3 for an AT wedge.

Code I.D.In the Symbology Chart, beginning on page A-1, find the symbology to which you want to apply the data format. Locate the Hex value for that symbology and scan the 2 digit hex value from the Programming Chart inside the back cover of this manual.Step 5. LengthSpecify what length (up to 9999 characters) of data will be acceptable for this symbology. Scan the four digit data length from the Program-ming Chart inside the back cover of this manual. (Note: 50 characters is entered as 0050. 9999 is a universal number, indicating all lengths.) Step 6. Editor CommandsRefer to Data Format Editor Commands (page 6-2).

2020/4820/4820 i User’s Guide 8 - 18Imaging CommandsThe image scanner can be used as a digital camera for capturing, manipulating, and transferring images.Imaging Commands with their modifiers send imaging commands to the image scanner on a single-use basis, and take effect for the next subsequent image capture. Once that capture is complete, the image scanner reverts to its imaging default settings. If you wish to change a default setting, you must use the serial default command (see Imaging Default Commands on page 12-21). When the serial default command is used, that selection becomes the new default setting for the image scanner.Image Snap - IMGSNPAn image is taken whenever the trigger of the image scanner is pressed, or when the Image Snap (IMGSNP) command is processed. Image Snap is the command processor for image capture, or taking a picture. The image snap command has many different modifiers that can be used to change the look of the image in memory. Modifiers always begin with numbers and end with a letter (case insensitive). Any number of modifiers may be appended to the IMGSNP command. For example, you can use the following command to snap an image, increase the gain, and have the beeper sound once the snap is complete:IMGSNP2G1BIMGSNP ModifiersP - Imaging Style: Sets the Image Snap style.0P Decoding Style. This is similar to the current format for decoding, however, this processing allows a few frames to be taken until the exposure parameters are met. Then the last frame is available for further use.1P Photo Style (default). This attempts to mimic a simple digital camera, and results in a visually optimized image.2P Manual Style. This is an advanced style, and should not normally be used. It allows you the most freedom to set up the image scanner, and has no auto-exposure.B - Beeper: Causes a beep to sound after an image is snapped.0B No beep (default)1B Sounds a beep when the image is captured, notifying the user that the image scanner can be moved. E - Exposure: This allows you to set the exposure time. Units are 127 microseconds. Exposure is used in Manual Style only. (Default = 7874) nE Range: 1 - 7874

Delta is only available when using Photo Style. (Default = 25)nD Range: 0 - 255L - LED State: Determines if the LEDs should be on or off, and when. Ambient illumination (0L) is preferred for taking pictures of color documents, such as ID cards, especially when the image scanner is in a stand. LED illumination (1L) is preferred when the image scanner is hand held. LED State is not available when using Decoding Style. 0L LEDs off (default)1L LEDs on T - Wait for Trigger: Waits for a hardware trigger pull before taking the image. 0T Takes image immediately (default)1T Waits for a trigger pull, then takes the image. This option only works with Imaging Style 1P (Photo Style). Refer to page 8-1.U - Update Tries: The maximum number of frames the image scanner should take to reach the Delta for Acceptance. Update Tries is only available when using Photo Style. (Default = 6)nU Range: 0 - 10W - Target White Value: Sets the target for the median grayscale value in the captured image. For capturing close-up images of high contrast documents, a lower setting, such as 75, is recommended. Higher settings result in longer exposure times and brighter images, but if the setting is too high, the image may be overexposed. Target White Value is only available when using Photo Style. (Default = 125)nW Range: 0 - 255% - Target Set Point Percentage: Sets the target point for the light and dark values in the captured image. A setting of 75% means 75% of the pixels are at or below the target white value, and 25% of the pixels are above the target white value. Altering this setting from the default is not recommended under normal circumstances. To alter grayscale values, Target White Value should be used. (Default = 50)n% Range: 1 - 99Image Ship - IMGSHPAn image is taken whenever the trigger of the image scanner is pressed, or when the Image Snap (IMGSNP) command is processed. The last image is always stored in memory. You may “ship” the image by using the IMGSHP command.
2020/4820/4820 i User’s Guide 8 - 3The image ship command has many different modifiers that can be used to change the look of the image output by the image scanner. Modifiers affect the image that is transmitted, but do not affect the image in memory. Modifiers always begin with numbers and end with a letter (case insensitive). Any number of modifiers may be appended to the IMGSHP command. For example, you can use the following command to ship a bitmap image with gamma correction and document image filtering:IMGSHP8F75K26U IMGSHP ModifiersA - Infinity Filter: Enhances pictures taken from very long distances (greater than 10 feet or 3 m).0A Infinity filter off (default)1A Infinity filter onC - Compensation: Flattens the image to account for variations in illumination across the image.0C Compensation disabled (default)1C Compensation enabledD - Pixel Depth: Indicates the number of bits per pixel in the transmitted image (KIM or BMP format only).8D 8 bits per pixel, grayscale image (default)1D 1 bit per pixel, black and white imageE - Edge Sharpen: Causes the transmitted image to be convolved with an edge sharpening filter.

2020/4820/4820 i User’s Guide 8 - 7Intelligent Signature Capture - IMGBOXNote: IMGBOX commands can only be used with PDF417, Code 39, Code 128, Aztec, Codabar, and Interleaved 2 of 5 symbologies.Intelligent signature capture ships only part of an image to the host application. This method reduces transfer time and file size, while simplifying signature capture.Below is an example of an intelligent signature capture application. In this example, the operator reads the barcode, which is then transmitted to the host application. Upon the receipt of the barcode data, the host application sends the IMGBOX command, which tells the image scanner to output only the area of the image corresponding to the signature capture box. The image scanner also automatically adjusts for aspect ratio and distortion, issues that arise due to image scanner skew with respect to the barcode.Align the aimers with the signature area (not with the barcode), then pull the trigger. Send the IMGBOX command string after the trigger pull.An important aspect of intelligent signature capture is that all dimensions used in the application are measured as multiples of the minimum element size of the barcode. Using this method, intelligent signature capture always outputs the correct image size and resolution, no matter the distance at which the image scanner is held from the barcode, assuming that the entire signature capture area is within the image scanner’s field of view.The intelligent signature capture command string for this application is:IMGBOX40S0X70Y190W100H1R0FIMGBOX ModifiersA - Output Image Width: This option is used to output an image of a particular width. If using this option, set the resolution to zero.B - Output Image Height This option is used to output an image of a particular height.

The value for H is slightly larger, to accommodate some extra image capture area outside of the signature capture box.K - Gamma Correction: Gamma measures the brightness of midtone values produced by the image. You can brighten or darken an image using gamma correction. A higher gamma correction yields an overall brighter image. The lower the setting, the darker the image. A setting of 100 results in no adjustment to the image. (Default = 50K)0K Gamma correction off 50K Apply gamma correction for brightening typical document imagenK Apply gamma correction factor n (n = 1-255)R - Resolution of Signature Capture Area: The number of pixels that the image scanner outputs per each minimum bar width. The higher the value for R, the higher the quality of the image, but also the larger the file size. To specify a non-integer value for the resolution, use a number greater than or equal to 1000. For example, use 2500 to specify a resolution of 2.500. The image scanner automatically inserts a decimal point between the first and second digit. Set to zero when using the A and B modifiers.S - Barcode Aspect Ratio: The ratio of the barcode height to the narrow element width. In the example, the narrow element width is .010 inches and the barcode height is 0.400 inches, resulting in a value of S = 0.4/0.01 = 40.W - Width of Signature Capture Area: In the example, the width of the area to be captured is 1.90 inches, resulting in a value of W = 1.9/0.01 = 190. The value for W is slightly larger, to accommodate some extra image capture area outside of the signature capture box.X - Horizontal Barcode Offset: The horizontal ratio offset of the center of the signature capture area, in multiples of the minimum bar width. In the example, the horizontal offset is 0.Y - Vertical Barcode Offset: The vertical offset of the center of the signature capture area, in multiples of the minimum bar width. Negative numbers indicate that the signature capture is above the barcode, and positive numbers indicate that the area is below the barcode. In the example, the horizontal offset is 0.70 inches, resulting in a value for Y = 0.7/0.01 = 70.
2020/4820/4820 i User’s Guide 8 - 9RF Default Imaging DeviceThe image scanner supports imaging command processing (IMGSHP, IMGSNP, IMGBOX) so that Quick*View (see "Quick*View" on page 11-5) and other applications are able to perform imaging functions as if they were talking directly to an image scanner. To accomplish this, the image scanner uses a menu command called RF_DID (RF Default Imaging Device). RF_DID is the name of the image scanner (BT_NAM) that is to receive imaging commands. The default for RF_DID is “*”indicating that imaging commands are to be sent to all associated image scanners. Change this setting to RF_DIDimage scanner_name to ensure that they are sent to a particular image scanner. Refer to "Image Scanner Report" on page 11-2 to generate a report containing the port, work group, image scanner name, and address for each image scanner. Refer to "Image Scanner Name" on page 3-8 set a unique name for each image scanner.

The image scanner reads 6 to 60 point OCR typeface.Note: OCR is not as secure as barcodes. To enhance security in OCR applications, create an OCR template to match the data and print an OCR check character.The image scanner will read OCR-A, OCR-B, U.S. Currency Serial Number (Money), MICR E-13B, and SEMI Font.You can either select an OCR default, or create your own custom template for the type of OCR format you intend to read. See "OCR" on page 9-1 for programming codes that will enable your image scanner to read OCR-A, OCR-B, U.S. Currency, MICR E 13 B, or SEMI fonts. See "OCR Templates" on page 9-3 if you want to create a custom “template,” or character string that defines the length and content of OCR strings that will be read with your image scanner.Note: Setting the template and check character options are essential for OCR reading.OCR FontsDefault All OCR Settings turns off all OCR capability in the image scanner, so the image scanner will be able to scan linear, stacked, matrix, and composite barcodes, but not OCR fonts.

9 - 4 2020/4820/4820 i User’s GuideCreating an OCR TemplateA single template allows you to program the image scanner to read any combination of characters in the order you specify. Refer to examples that follow the Template Characters table below.Template CharactersNote: OCR templates default to eight digits, no check character. To Add an OCR Template1. Turn on the OCR font you want to read (page 9-2).2. Begin building the template.Scan the Enter OCR Template symbol (page 9-13).3. Scan the characters for the string.Use the Template Characters chart above to determine what characters you need to create your format. Use the OCR Programming Chart (after the Sample Codes in the back of this manual) to scan the characters for your template. Example: You need to read any combination of eight digits. The template would be:a represents any alphanumeric character (digit or letter)c represents a check character positiond represents any digite represents any available OCR characterg represents character from user-defined variable “g”h represents character from user-defined variable “h”i represents character from user-defined variable “g” or “h”k represents that a check character is verified but transmittedl represents any uppercase lettert marks the start of a new templater multi row indicatorAll other characters represent themselves.

Discard OCR Template exits without saving any OCR Template changes. Stringing Together Multiple Formats (Creating “Or” Statements)You may want to program the image scanner to accept many OCR formats. To do this, you would string together each format with a “t.” This tells the image scanner to read optical characters that match any one of the formats in the template.Example: You need to read any combination of eight digits, or a combination of four digits, two uppercase letters, and two digits. The template would be:ddddddddtddddllddTo create this template, you would enable the OCR-A font. Scan the Enter OCR Template symbol (page 9-13). Scan the d from the OCR Programming Chart in the back of this manual eight times, then scan the t to create the “or” statement. Then you would scan the characters for the second template. Scan d four times, scan l two times, then scan d two more times. Scan Save OCR Template (page 9-14). This would let you read either type of format, for example:99028650or9902XZ50You can string together as many templates as you need.
2020/4820/4820 i User’s Guide 9 - 7OCR User-Defined VariablesYou can create up to two of your own user variables for an OCR template. These variables will represent any OCR readable characters. The user-defined variables are stored under the letters “g” and “h.” Creating a user variable follows the same steps as creating a template, but instead of scanning the Enter OCR Template symbol, you scan the Enter User-Defined Variable symbol (page 9-13). The letters g and h can then be used in an OCR template to define the variable you specified.Example: You need a variable to represent the letters “A,” “B,” or “C.” The template for this variable would be:414243To create this template, you would enable the OCR-A font. Scan the Enter User-Defined Variable g symbol (page 9-13). Scan 414243 from the Programming Chart (the hex characters for “A,” “B,” and “C”). Scan Save OCR Template (page 9-14). This will let you read either A or B or C in any position where you place the g. For example, you could create the following template:ddddddgggThis template would then let you read data that began with six digits, and had an A, B, or C trailing. So you would be able to read:654321ABCor654321BACor654321CCCReading Multi-Row OCRThe image scanner is capable of decoding multi-row OCR text. Note: Reading rows longer than sixteen characters is not recommended.Consider the following example. This example shows serial commands as they would be entered using Quick*View.Example: You need to read multiple rows of OCR-A data as shown below:12345678ABCDEFGHFirst, enable the OCR-A font. To read the first row of OCR data, you would program the following template:
9 - 8 2020/4820/4820 i User’s GuideOCRTMP"dddddddd".This template is the default OCR template. If you wanted to read the second line of data, you would use the following template: OCRTMP"llllllll".To read both lines of OCR at one time, use the variable r to indicate the start of a new row. All the other templating variables for the individual rows work the same as previously described. For instance, in the above example, you would use the following template to read both rows:OCRTMP"ddddddddrllllllll".To read the three rows below, you would use the template command "OCRTMP"ddddddddrllllllllrlllldddd".12345678ABCDEFGHABCD1234OCR Check CharacterYou may want to print and verify a check character in order to enhance the security of your OCR application. The image scanner can be programmed for almost any type of check character. A number of presets are provided for common check character uses (e.g., modulo 10 and modulo 36).Scan the OCR Modulo 10 or OCR Modulo 36 Check Character barcode to specify the type of check character used in the OCR strings you’re scanning. The image scanner will then only read OCR character strings with a valid check character. The image scanner transmits the OCR data without the check character data. You must specify the location of the check character in the template with a c.Example: You need to read any combination of seven digits, with a modulo 10 check character in the eighth position. The template would be:dddddddcTo create this template, you would enable the OCR-A font. Scan the Modulo 10 Check Character symbol. Then scan the Enter OCR Template symbol, and scan the d from the OCR Programming Chart seven times, and scan the c once. Scan Save OCR Template (page 9-14). This template will let you read any combination of six digits with a correct check character after. (If the check character is invalid, data is discarded.) For example, the following string could be scanned:01234569and the output would be: 0123456

Each character of the check character alphabet can be programmed in its proper order. The number of characters you enter determines the modulo value for the calculation. By default, the check character computation is unweighted, but the image scanner also supports two weighted modulo 10 checking schemes.Example: To program a modulo 11 check character, you would enter the following 11 characters in order:0123456789XAlso enter the OCR template:dddddddcEnable the OCR-A font, then scan the following string:6512351XThe image scanner performs the following check character computation:(6 + 5 + 1 + 2 +3 + 5 + 1 + X) modulo 11 = 0Since the result is zero, the message is considered to be valid, so the reader outputs the message: 6512351OCR Modulo 10 Check Character OCR Modulo 36 Check Character

For each character, look up the corresponding hex value from the Code Page Mapping of Printed Barcodes on page A-6. Use the Programming Chart on the inside the back cover of this manual to scan the two symbols for each hex value.3. Scan the Save barcode on the inside back cover.Example: To program the modulo 11 check character from example #8 on page 9-9, enable the OCR-A font.

It is possible to use one of two weighted modulo 10 schemes. Weighting is often used to detect if two neighboring characters are transposed, a common error when an operator keys in data.3-1-3-1 Weighted Modulo 10 Check CharacterStarting with the check character and working backward through the message, the image scanner applies a multiplier of 1, then 3, then 1, then 3, and so on. This is the checking scheme used in many EAN•UCC symbologies, including U.P.C. and Interleaved 2 of 5 (when a check digit is invoked). To apply this weighting scheme, set the OCR check character to “0123456789x3x1” or scan the following symbol:Enter OCR Check Character3-1-3-1 Weighted Modulo 10 Check Character

When the result of the multiplication is greater than 9, add both digits to the running sum. This is often referred to as the LUHN formula. One common application of the LUHN formula is validate credit card numbers. This is the modulo 10 checking scheme used in MSI Code and in Code 32 Pharmaceutical (PARAF). To apply this weighting scheme, set the OCR check character to "0123456789x2x1" or scan the following symbol:Example: Scan the 2-1-2-1 Weighted Modulo 10 Check Character symbol.

9 - 12 2020/4820/4820 i User’s GuideOCR ISBN Application ExampleOne application of OCR is to read the ISBN characters typically encoded using the OCR-A or OCR-B font. This is especially useful when the ISBN number is not encoded in an EAN-13 barcode. The following example shows how to configure the image scanner to read the ISBN strings on books in Japan. After you have followed the steps below, you will be able to scan the following ISBN number or the additional data below it, depending on the line of text at which the image scanner is aimed.1. Scan the OCR-B On barcode on page 9-2.2. Program the user-defined variable “g” to comprise the ten digits plus the dash:0123456789-3. In Japan, it is common for two fields to follow the ISBN number, the three digit price field, and the four digit price field. The first field typically starts with a “C” (uppercase c), followed by four digits. The second field typically starts with a “P” or a yen symbol, followed by three or four digits, followed by an “E.” Program the user-defined variable “h” to comprise the “P” and the yen symbol (represented by a backslash).P\4. Scan the symbol below to set up three templates to handle the ISBN number, the three digit price field, and the four digit price field.
2020/4820/4820 i User’s Guide 9 - 135. Finally, set up the ISBN check digit, which is a special position-weighted modulo 11 checksum. The image scanner automatically invokes the ISBN checksum for template rows that are: 1.) at least fourteen characters long, 2.) whose first four characters are the letters “ISBN,” 3.) whose last character is a check character, and 4.) when the modulo 11 check character “0123456789X” is programmed.Please note that all these commands can be combined into a single serial programming command:OCRENA2,TMP”ISBNggggggggggggctCdddd hdddEtCddddhddddE”,GPG”0123456789-”,GPH”P\”,CHK”0123456789X”.These commands can be encoded into the following Aztec Code symbol:OCR Template CodesNote: Reading more than three rows of OCR is not recommended.

11 - 4 2020/4820/4820 i User’s GuideTest MenuWhen you scan the Test Menu On code, then scan a programming code in this manual, the image scanner displays the content of a programming code. The programming function will still occur, but in addition, the content of that programming code is output to the terminal. Note: This feature should not be used during normal image scanner operation.Visual XpressVisual Xpress provides a wide range of PC-based programming functions that can be performed on an image scanner connected to your PC's COM port. Visual Xpress allows you to download upgrades to the image scanner's firmware, change programmed parameters, and create and print programming barcodes. Using Visual Xpress, you can even save/open the programming parameters for an image scanner. This saved file can be e-mailed or, if required, you can create a single barcode that contains all the customized programming parameters and mail or fax that barcode to any location. Users in other locations can scan the barcode to load in the customized programming. To communicate with an image scanner, Visual Xpress requires that the PC have at least one available serial communication port, or a serial port emulation using a physical USB port. If you are using the serial port and RS-232 cable, an external power supply is required. When using a USB serial port emulation, only a USB cable is required.Visual Xpress OperationsThe Visual Xpress software performs the following operations:Scan DataScan Data allows you to scan barcodes and display the barcode data in a window. Scan Data lets you send serial commands to the image scanner and receive image scanner response that can be seen in the Scan Data window. The data displayed in the Scan Data window can either be saved in a file or printed. On* Off
2020/4820/4820 i User’s Guide 11 - 5ConfigureConfigure displays the programming and configuration data of the image scanner. The image scanner's programming and configuration data is grouped into different categories. Each category is displayed as a tree item under the "Configure" tree node in the application explorer. When one of these tree nodes is clicked, the right-hand side is loaded with the parameters' form belonging to that particular category. The "Configure" tree option has all the programming and configuration parameters specified for an image scanner. You can set or modify these parameters as required. You can later write the modified settings to the image scanner, or save them to a dcf file. ImagingImaging provides all the image-related functions that a 2D Image Scanner can perform. You can capture an image using the current settings, and the image will be displayed in an image window. Images captured from the image scanner can be saved to files in different image formats. You can modify the image settings and save the image settings to an INI file, which can be loaded later to capture new images. Imaging also lets you preview the images continuously captured by the image scanner. Installing Visual Xpress from the Web1. Access the Hand Held Products web site at www.handheld.com.2.

2020/4820/4820 i User’s Guide 12 - 112Serial Programming CommandsThe serial programming commands can be used in place of the programming barcodes. Both the serial commands and the programming barcodes will program the image scanner. For complete descriptions and examples of each serial programming command, refer to the corresponding programming barcode in this manual.The device must be set to an RS-232 interface (see page 2-2). The following commands can be sent via a PC COM port using terminal emulation software.ConventionsThe following conventions are used for menu and query command descriptions:parameterA label representing the actual value you should send as part of a command.[option] An optional part of a command.{Data} Alternatives in a command.bold Names of menus, menu commands, buttons, dialog boxes, and windows that appear on the screen.Menu Command SyntaxMenu commands have the following syntax (spaces have been used for clarity only):Prefix [:Name:] Tag SubTag {Data} [, SubTag {Data}] [; Tag SubTag {Data}] […] StoragePrefix Three ASCII characters: SYN M CR (ASCII 22,77,13).:Name: To send information to the image scanner (with the base connect-ed to host), use :4820: or :4820i: The default factory setting for a 4820 image scanner is 4820, and 4820i for a 4820i image scanner. This setting is changed by using the BT_NAM command, which ac-cepts alphanumeric values. If the name is not known, a wildcard (*) can be used :*:.Note: Since the base stores all work group settings and transfers to them to image scanner once they are linked, changes are typically done to the base and not to the image scanner.Tag A 3 character case-insensitive field that identifies the desired menu command group. For example, all RS-232 configuration settings are identified with a Tag of 232.SubTag A 3 character case-insensitive field that identifies the desired menu command within the tag group. For example, the SubTag for the RS-232 baud rate is BAD.Data The new value for a menu setting, identified by the Tag and Sub-Tag.
12 - 2 2020/4820/4820 i User’s GuideStorage A single character that specifies the storage table to which the command is applied. An exclamation point (!) performs the com-mand’s operation on the device’s volatile menu configuration table. A period (.) performs the command’s operation on the device’s non-volatile menu configuration table. Use the non-volatile table only for semi-permanent changes you want saved through a power cycle.Query CommandsSeveral special characters can be used to query the device about its settings.^What is the default value for the setting(s).?What is the device’s current value for the setting(s).*What is the range of possible values for the setting(s). (The de-vice’s response uses a dash (-) to indicate a continuous range of values. A pipe (|) separates items in a list of non-continuous val-ues.):Name: Field Usage (Optional)This command returns the query information from the image scanner.Tag Field UsageWhen a query is used in place of a Tag field, the query applies to the entire set of commands available for the particular storage table indicated by the Storage field of the command. In this case, the SubTag and Data fields should not be used because they are ignored by the device. SubTag Field Usage When a query is used in place of a SubTag field, the query applies only to the subset of commands available that match the Tag field. In this case, the Data field should not be used because it is ignored by the device.Data Field UsageWhen a query is used in place of the Data field, the query applies only to the specific command identified by the Tag and SubTag fields.Concatenation of Multiple CommandsMultiple commands can be issued within one Prefix/Storage sequence. Only the Tag, SubTag, and Data fields must be repeated for each command in the sequence. If additional commands are to be applied to the same Tag, then the new command sequence is separated with a comma (,) and only the SubTag and Data fields of the additional command are issued. If the additional command requires a different Tag field, the command is separated from previous commands by a semicolon (;).
2020/4820/4820 i User’s Guide 12 - 3ResponsesThe device responds to serial commands with one of three responses:ACK Indicates a good command which has been processed.ENQ Indicates an invalid Tag or SubTag command. NAK Indicates the command was good, but the Data field entry was out of the allowable range for this Tag and SubTag combination, e.g., an entry for a minimum message length of 100 when the field will only accept 2 characters.When responding, the device echoes back the command sequence with the status character inserted directly before each of the punctuation marks (the period, exclamation point, comma, or semicolon) in the command.Examples of Query CommandsIn the following examples, a bracketed notation [ ] depicts a non-displayable response.Example #1:What is the range of possible values for Codabar Coding Enable?Enter: cbrena*.Response: CBRENA0-1[ACK]This response indicates that Codabar Coding Enable (CBRENA) has a range of values from 0 to 1 (off and on). Example #2: What is the default value for Codabar Coding Enable?Enter: cbrena^.Response: CBRENA1[ACK]This response indicates that the default setting for Codabar Coding Enable (CBRENA) is 1, or on. Example #3: What is the device’s current setting for Codabar Coding Enable?Enter: cbrena?.Response: CBRENA1[ACK]This response indicates that the device’s Codabar Coding Enable (CBRENA) is set to 1, or on.
12 - 4 2020/4820/4820 i User’s GuideExample #4: What are the device’s settings for all Codabar selections?Enter: cbr?.Response: CBRENA1[ACK],SSX0[ACK],CK20[ACK],CCT1[ACK],MIN2[ACK],MAX60[ACK],DFT[ACK].This response indicates that the device’s Codabar Coding Enable (CBRENA) is set to 1, or on; the Start/Stop Character (SSX) is set to 0, or Don’t Transmit; the Check Character (CK2) is set to 0, or Not Required;concatenation (CCT) is set to 1, or Enabled; the Minimum Message Length (MIN) is set to 2 characters; the Maximum Message Length (MAX) is set to 60 characters; and the Default setting (DFT) has no value. Trigger CommandsYou can activate and deactivate the image scanner with serial trigger com-mands. First, the image scanner must be put in Manual/Serial Trigger Mode either by scanning the Manual/Serial Trigger Mode barcode (page 4-4), or by sending the Manual/Serial Menu Command (page 12-9). Once the image scan-ner is in serial trigger mode, the trigger is activated and deactivated by sending the following commands:Activate: SYN T CRDeactivate: SYN U CRThe image scanner scans until a barcode has been read, until the deactivate command is sent, or until the serial time-out has been reached (see "Read Time-Out (Serial Trigger Mode)" on page 4-4 for a description, and the serial command on page 12-9).

In some cases, the image scanner’s battery may trickle charge to bring it into an acceptable level and then transition to a normal charge cycle.Troubleshooting Image ScannerNote: Make sure that your image scanner’s battery is charged.Note: Please visit the Services and Support section of our website (www.handheld.com) to check for the latest software for both the image scanner and the base.Is the image scanner having trouble reading your symbols?If the image scanner isn’t reading symbols well, check that the symbols:• Aren’t smeared, rough, scratched, or exhibiting voids.• Aren’t coated with frost or water droplets on the surface.• Are enabled in the base to which the image scanner connects.Is the barcode displayed but not entered into the application?The barcode is displayed on the host device correctly, but you still have to press a key to enter it (the Enter/Return key or the Tab key, for example).You need to program a suffix. Programming a suffix enables the image scanner to output the barcode data plus the key you need (such as “CR”) to enter the data into your application. Refer to Prefix/Suffix Overview on page 5-1 for further information.Does the image scanner read the barcode incorrectly?If the image scanner reads a barcode, but the data is not displayed correctly on the host screen:• The base may not be programmed for the appropriate terminal interface. For example, you scan “12345” and the host displays “@es%.”Reprogram the base with the correct Plug and Play or Terminal selection barcode. See Chapter 1 and Chapter 2.• The base may not be programmed to output your barcode data properly.For example, you scan “12345” and the host displays “A12345B.”Reprogram the base with the proper symbology selections. See Chapter 7.The image scanner won’t read your barcode at all.1. Scan the sample barcodes in the back of this manual. If the image scanner reads the sample barcodes, check that your barcode is readable.Verify that your barcode symbology is enabled (see Chapter 7).

2020/4820/4820 i User’s Guide B - 1BMinimizing Bluetooth/ISM Band Network ActivityThe settings described below can help you customize the re-linking behavior of the cordless linear imaging system to obtain the best compromise between convenience and low interference.Note: ISM band refers to the 2.4 to 2.48 GHz frequency band used by wireless networks, cordless phones, and Bluetooth.Auto Reconnect ModeAuto Reconnect controls whether or not the image scanner automatically begins the re-link process when a loss of connection is detected. When the Auto Reconnect On barcode is scanned, the image scanner begins the re-link process immediately, without user intervention. Default = Auto Reconnect On.The table below shows the results of the Auto Reconnect On and Off settings: Event Auto Reconnect On Auto Reconnect OffImage scanner out of rangeRe-link occurs automatically. If maximum number of link attempts (see Maximum Link Attempts on page B-2) is unsuccessful, then the trigger must be pulled or the image scanner must be placed in the base unit to re-link.The trigger must be pulled to initiate re-linking.Base reset (firmware upgrade or power cycle)Image scanner behaves as if out of range.No attempt to re-link made while base unit is powered off. Trigger must be pulled to initiate re-linking.* Auto Reconnect OnAuto Reconnect Off
B - 2 2020/4820/4820 i User’s GuideMaximum Link AttemptsThe Maximum Link Attempts setting controls the number of times the image scanner tries to form a connection with a base unit or PC. During the connection setup process, the image scanner transmits in order to search for and connect to a base unit. In order to prevent continuous transmissions that could interfere with other users of the ISM band, the number of attempts to connect is limited by this setting. After the maximum number of attempts is reached, the image scanner will not attempt to reconnect to the base unit. Pressing the trigger or placing the image scanner in the cradle resets the attempt count and the image scanner will again try to link to the base unit. When set to zero, the image scanner will try to link until the Power Time-Out Timer setting (see page 4-4) expires. Scan the Maximum Link Attempts barcode, then scan the number of attempts for the setting (from 0-100) from the inside back cover. Scan Save to save the setting. Default = 0.Image scanner power down due to Power Time-Out Timer setting (see page 4-4)Trigger must be pulled or the image scanner must be placed in the base unit to re-link.(Note: image scanner re-links on power up, but powers on due to one of the above actions.)Image scanner reset due to firmware upgradeRe-link occurs automatically.Image scanner reset due to battery changeRe-link occurs automatically.Image scanner placed in different base unitRe-link to new base occurs automatically.Event Auto Reconnect On Auto Reconnect OffMaximum Link Attempts
2020/4820/4820 i User’s Guide B - 3Relink Time-OutRelink Time-Out controls the idle time between re-link attempts. An attempt to link an image scanner to a base unit typically lasts up to 5 seconds. This is the time when the image scanner is actually attempting to contact base unit. Relink Time-Out controls the amount of time, in seconds, that elapses between the end of one connection attempt and the start of the next.Note: The length of time for an attempt depends on the number of image scanners connected to a base unit. An extra 7 seconds may be required when a connection is successful.Scan the Relink Time-Out barcode, then scan the number of seconds for the setting (from 1-100) from the inside back cover. Scan Save to save the setting. Default = 3 seconds.Bluetooth/ISM Network Activity ExamplesDefault values:When the image scanner goes out of range, the image scanner repeatedly attempts to connect to base unit. Each attempt consists of approximately 5 seconds of active time followed by 3 seconds of idle time. After one hour, the image scanner powers off and batch mode data is lost.Maximum Link Attempts set to 15Other values at default setting:When the image scanner goes out of range, 15 attempts are made to link to the base unit. Each attempt consists of approximately 5 seconds of active time followed by 3 seconds of idle time. After 15 cycles (8*15 =120), or about 2 minutes, the image scanner stops trying to connect to the base unit, but retains any barcodes that may have been saved in batch mode. After one hour, the image scanner powers off and batch mode data is lost.Auto Reconnect Mode set to 0Maximum Link Attempts set to 15Other values at default setting:When the image scanner goes out of range, no action is taken to re-link. When the trigger is pulled, 15 attempts are made to link to the base unit. Each attempt consists of approximately 5 seconds of active time followed by 3 seconds of idle time.
