Enclosure Description

Quick Check SV Series

Introduction

The Hand Held Products SV Series of Scanner/Verifiers is a universal system component that analyzes linear bar code print quality, checks encoded data, and detects system failures. In its basic mode of operation, an SV unit acts similar to a normal fixed position scanner by automatically decoding bar codes as they pass through its laser beam. Additional capabilities, such as performing bar code verification and operating in synchronous modes make the SV Series unique.

The SV Series combines state-of-the-art digital signal processor (DSP) technology, a proprietary high-speed moving beam laser scanner with unique analog output capability, and flexible I/O and communications capability. This powerful architecture makes an SV unit an economical Quality Assurance tool for practically any bar code print, application, or conveyance system.

The SV Series performs practically every accepted method of bar code verification – ISO method, traditional method, encoded data format checks, and laser scanning type analyses. These wide-ranging analysis parameters can be used to measure bar code quality and detect failure mechanisms for any print technology.

Bar code quality and encoded data information can be reported through the serial communications port for each code analyzed, so accountability for all printed bar codes is possible.

An SV Unit’s I/O consists of five programmable output ports, two programmable display LED’s, and a sync input (with two interface circuit choices). This allows the unit to be used as a local controller for pausing printers, activating lights, gating conveyors, etc.

The SV Series is available in different models. All models operate identically, but the scanner parameters, such as scans per second and focus distance, are different.

Control Panel

The control panel displays the reset button, I/O connector, system LEDs, and the serial port connector.

Reset Button

The Reset button is multifunctional. It may be used to turn off the laser beam, perform calibration, and reset the ports.

Turn Off Laser Beam

The laser beam may be turned off (therefore turning off the SV unit’s operation) by holding down the Reset button for a few seconds until the beam turns off. Pressing the Reset button again will begin normal operation.

Note: There are some modes of operation when the laser beam is on only

during specific scanning times. (See the ~SA command (page 6-24) in

Chapter 6, SV Command Language) Using the Reset Button for turning

off the system is not recommended in these modes.

Perform Calibration

The reset button is used in the calibration procedures. See "Calibration" on

page 5-8 for details.

Reset Ports

Pressing the Reset button will reset ports to their inactive states. This is useful in systems where the SV unit is holding a printer in PAUSE mode and the user desires to clear the pause condition. See "Output Ports" on page 2-5 for details.

I/O Connector

The I/O connector is used for all power and field interconnections. The connector is a DB 15 male. Pin-outs are shown below:

+ 5 VDC Power Input

The SV Series requires + 5 Volts DC, +/- 0.25 Volt. Maximum current consumption is 1 amp. The voltage input must be connected to pin 12 and the ground input should be connected to pin 13 on the I/O connector.

The alternate ground pins (3, 11, and 14) may be used for power ground or for connecting the ground(s) of an external device(s) (such as presence sensors) that may be powered from a different source than the verifier power input.

Sync Inputs

Utilizing a sync signal is recommended for all applications using hardware (as opposed to communication) interfaces. (See "SV Command Language" on

page 6-1.) A sync signal is used to synchronize the SV Series to an object, label,

etc. that contains the bar code(s) being analyzed as it passes through the laser beam. The SV Series should be programmed for the number of bar codes expected per sync interval. This ensures a robust system that can report all undetectable bar codes due to printer failure, missing labels, etc., along with quality and data information on bar codes that are fully or partially decoded.

Two hardware sync inputs are available. Pin 4 is designed to be used with TTL or open collector inputs. For open collector inputs, adding an external pull-up resistor to 5 VDC is recommended because the internal pull-up is a relatively high 100K ohm resistance. Pins 1 and 2 form a ground isolated input designed to be used with systems that need separate grounds than the verifier and/or output a higher voltage level than TTL. See the figures the follow for circuit diagrams.

command for details.

Hardware sync operation is very flexible due to programmable options. Two sync modes, edge and envelope, are available. Signal input polarity is also user programmable.

Please see "SV Command Language" on page 6-1 for more information on the use of these sync modes.

Quick Check® SV Series User’s Guide 2 - 3

Edge Sync Mode

Sync sensed here

Sync period starts here

Sync period ends here

This mode senses a signal transition level of a sync signal as shown below.

The illustration above shows the sync operation of an SV unit programmed to sense the rising edge of a sync signal in edge mode. Each time a rising edge is sensed, the SV unit does the following:

1. It verifies that at least the number of bar codes expected (programmed) since receiving the last sync input have been fully decoded. If not, a No Read condition is internally set for possible reporting through communication or output activation.

2. It begins a new interval, counting the bar codes analyzed until the next sync input is received.

3. A serial communication report is transmitted and an output port is updated per its programmed function each time a bar code is analyzed.

Envelope Sync Mode

This mode senses two transitions (leading and trailing) of the sync signal to determine when to begin and end the period for determining missing bar codes:

The illustration above shows the sync operation of an SV unit programmed to sense the rising voltage edge as the start of a sync period. The SV unit operates in this mode as follows:

1. Upon receipt of the starting edge of a sync signal, the unit begins counting the bar codes being scanned and analyzed.

2. A serial communication report is transmitted, and an output port is updated per its programmed function each time a bar code is analyzed.

Series determines that at least the number of bar codes expected (programmed) during the sync period have been fully decoded. If not, an internal No Read condition is set for possible reporting through communication or output activation.

4. The SV unit then waits for the next leading edge of a sync signal to begin counting codes being scanned and analyzed.

Note: For best performance in either sync mode, mount the SV unit in a location

where a bar code is not in the laser beam when an active edge signal is received.

Communication Sync Commands

Sync operation can be accomplished through serial communications. Please see the ~SK# (page 6-26) command for details.

Output Ports

Five programmable output ports are available on I/O connector pins 5, 6, 7, 8, and 15. Each port can be programmed to activate on practically any combination of data and analysis parameters (including “good codes”) analyzed by the SV Series. Port activation logic and parameters are programmed via the output interface modes and associated commands. See the "Output Interface Modes

Descriptions" on page 6-30 for details.

Each port’s output is an open drain FET (field effect transistor). Therefore, the port can either be “ON” (sinking current) or “OFF” (no current/open circuit). The active polarity determines whether the port is “ON” or “OFF” while active. This type of output circuit is used because it is flexible for field connections. The diagram below shows an example circuit diagram of one output port.

Quick Check® SV Series User’s Guide 2 - 5

System Displays

Five LEDs are included on the SV Series back panel.

Power/Sync LED

This LED is illuminated green whenever power is applied to the SV Series. Upon receipt of any sync input (hardware or serial communications), the LED blinks yellow for approximately 100 milliseconds.

Calibration LED

This yellow LED indicates calibration status. Please refer to "Calibration" on

page 5-8 for details.

Read LED

This green LED is illuminated whenever a bar code is being fully decoded.

Indicator LEDs 1 and 2

The two green indicator LEDs are user programmable exactly like the five output ports. Their functions are intended for use as indicators for specific analysis results.

A common example is programming LED 1 to illuminate in latch mode whenever a symbol quality error is detected, while programming LED 2 to illuminate in latch mode whenever a No Read error is detected.

Serial Port Connector

The serial port connector is used to interface the SV Series with devices incorporating RS-232C signal levels. The connector is a DB 9 male.

The serial port can be used for reporting bar code analysis results to a host and receiving SV Command Language instruction from a host.

ScanView Installation and Setup

Introduction

ScanView is designed to be a tool used for system setup and real-time bar code monitoring of a Hand Held Products SV type scanner/verifier. It is a Windows 2000/XP application with facilities for sending commands to the SV scanner/ verifier and receiving the responses. The program can view bar code analysis results and monitor bar code printing/monitoring sessions. In addition, it can gather and display an ISO method scan reflectance profile for a particular symbol placed in the SV unit’s laser beam scan path. ScanView also streams the analysis results received from the SV scanner/verifier to data files on hard disk that can be reviewed by ScanView at a later time.

Note: This chapter refers to ScanView versions 2.08 and higher.

Note: If you are not using ScanView, skip this section and go to Chapter 5.

System Requirements

The following hardware and software is required to use ScanView:

1. A computer running either Windows 2000 or XP.

2. At least one available RS-232 serial port.

3. At least 32 MB RAM.

4. A hard disk with at least 15 MB of free space.

5. A color printer is recommended for users who wish to print analysis results.

ScanView Software Installation

There are two basic steps for installing ScanView. The program must be installed and a communication port must be set up.

Note: Before installing a new version of ScanView make sure to uninstall

previously installed versions. To do this, select the Windows ‘Start’ button; the ‘Settings’ menu item; the ‘Control Panel’ to display the Control Panel Window. Double-click on the ’Add/Remove Programs’ icon. The ‘Add/Remove Programs Properties dialog box appears. Click on the ‘Install/Uninstall’ tab. Scroll the list box to locate the ‘ScanView by Hand Held Products’ item. Select that item and select the ‘Add/Remove’ button

Quick Check® SV Series User’s Guide 4 - 1

and follow the displayed instructions. If the previous version of ScanView was 2.07 or earlier, delete the folder that contains the remaining ScanView files: ‘c:/Program Files/Hand Held Products/ ScanView by Hand Held Products.’

Note: If you are using a CD-ROM, insert the CD and the system walks you

through the set up. If you are using 3.5 diskettes, follow the steps below.

Follow these steps to install ScanView:

1. Insert ScanView Installation Diskette #1 into a floppy disk drive; e.g., drive A.

2. Select the Windows 'Start' button.

3. Select 'Run...' menu item

4. Type A:\setup.exe.

5. Select ‘OK’ and follow the displayed installation instructions.

At the end of the installation procedure click the ‘Finish’ button to close the ScanView Installation program. The ScanView Group Window remains, and it contains the ScanView application icon. The icon label is ‘ScanView.exe’. To place a shortcut to ScanView on the Windows Desktop, hold down the right mouse button while dragging the ScanView icon to an open space on the desktop; then release the right mouse button. A menu will appear. Click on the ‘Create Shortcut(s) Here’ menu item.

Launch the ScanView application by double-clicking on the ScanView icon. (ScanView can also be launched by clicking the Windows ‘Start’ button, then by clicking the ‘Programs’ menu item, and finally, by clicking the ScanView submenu item.)

The first time ScanView is launched, a dialog box is displayed that shows all of the communications ports on the PC in a drop-down list. Select the communications port that is connected to the SV scanner/verifier.

The initial screen displayed after successful installation is the Bar Code Analysis Screen. This is shown in page 4-9 and described in the Analysis Screens section.

PC Communication Port Setup

Connect the null-modem cable between the SV unit and the PC serial com port.

The PC communication port settings must match the ScanView communication parameter settings. To match the communications port baud rate to the verifier baud rate, click the Setup item on the application Menu Bar (See "Bar Code

Analysis Screen" on page 4-9). Then click the ‘Match Verifier Baud rate” menu

item. ScanView will detect the verifier’s baud rate, and set the port to the detected value.

4 - 2 Quick Check® SV Series User’s Guide

Software Operation Warnings

Do not let other Windows applications run concurrently with ScanView. ScanView operation depends on communication and timing issues that can be disrupted when ScanView shares Windows resources with other applications. The resource sharing problem can include conflicts with Windows screensavers. ScanView blocks screensaver operation.

This version of ScanView limits the number of processed bar codes to 30,700 per session. To use ScanView for monitoring larger amounts of bar codes, divide the job into multiple sessions, each less than 30,700 bar codes.

Title Bar – Screen Display

See "Bar Code Analysis Screen" on page 4-9. The area marked B is the title bar. The application Title Bar is located at the top of the application window. It shows the application’s name and the name of the data file that receives the analysis results generated by the verifier. The title changes to identify the current display mode.

The Title Bar also includes the standard Windows Minimize, Maximize and Application Termination buttons.

Menu Bar – Screen Display

See "Bar Code Analysis Screen" on page 4-9. The area marked C is the Menu Bar. The Menu Bar is located just below the Title Bar. It lists five menu categories: File, Setup, Advanced, Support and About.

File Menu

This menu controls data file handling functions, printing and application termination. The format is typical of any Windows type file menu. The files contain the raw data collected from the SV unit. ScanView can re-open these files to re-display the data at a later time.

Note: The Print function prints the current ScanView display on the printer.

Setup Menu

This menu is used to configure the ScanView analysis displays and program the most common SV scanning and communication parameters.

Transmit SV Commands

This button invokes a special screen where up to fourteen individual commands may be composed and transmitted in any order. Proper use requires knowledge of the SV download language. See the Chapter 6, SV Download Language for details. This function is intended for advanced setup involving special functions not normally accessed by ScanView. These can include special transmission formats, special commands in a custom SV firmware version or diagnostic functions used by Hand Held Products’ Application Support and Service personnel. The shortcut key for this function is F4.

Report an Analysis

Reports a new analysis of any bar code(s) currently in the SV

unit’s beam path. This is most useful in setup where scan distance and orientation is being finalized. It is also useful when using the SV unit as a standalone verifier scanning codes being manually placed in the beam by the user. The shortcut key for this function is the Spacebar.

Modes Of Operation

ScanView operates in two basic modes: Session and Reflectance Profile.

Session Mode

This mode scans, analyzes and provides reports on individual bar codes. Reporting is accomplished via the Bar Code Analysis Screen (see "Bar Code

Analysis Screen" on page 4-9). The parameters analyzed and many of the

parameters displayed are user programmable

Session Mode is entered by default when the program is initially started. It can also be entered from the Reflectance Profile Mode by clicking the Return to Session Mode Speed button (see "Reflectance Profile Screen" on page 4-12.) The Bar Code Analysis Screen (see "Bar Code Analysis Screen" on page 4-9) is displayed and analysis from bar codes passing through the SV unit’s beam will be displayed. In cases where a bar code is statically held in the beam analysis of the code can be accessed by clicking the Report an Analysis Speed button.

Session Mode Notes

ScanView updates the bar code analysis graphs each time a bar code is processed by the verifier; but there is a limit to the graph update rate that ScanView can sustain. Factors that determine the processing load include the bar code analysis rate (bar codes per second) and the number of displayed analysis parameter graphs (selected by the user). The Windows communications facility has a data buffer that allows the graph processing to ‘catch up’ between bursts of transmitted data. If the incoming data volume

Quick Check® SV Series User’s Guide 4 - 7

exceeds the application’s processing limit it will lag farther and farther behind until the buffer overflows and the communications port ceases to operate. If this condition occurs, port operation can be restored by clicking the Initialize Com Port item in the Support Menu list. When using ScanView to monitor a printing session, the user can test for processing lag during short sample runs by intermittently blocking the beam path and noting the resulting analysis graph update lag. If the apparent lag time is longer when the time between blocking the beam is longer, then an adjustment is required; either reduce the speed the bar codes are traveling through the laser beam or change to a ScanView display mode that requires less graphic processing. (e.g., see "Toggle Display

Updating" on page 4-5)

ScanView streams the verifier analysis results directly to data files on hard disk as the data are received from the verifier. There are two data files: one, contains the verifier analysis results; the other file contains the date and time when each bar code was processed (supplied by the PC clock). The two default files are deleted and a new pair of default files are created each time the ScanView application is launched. Therefore, the user must rename the files to preserve session analysis results. To do this, use the ‘Save As’ item in the File Menu. Enter a filename without a trailing file-type identifier. ScanView uses that name to create two files: one, for the session analysis results data (.ses); and the other for the date/time data (.tim).

When ScanView is launched it exhibits the same configuration it had when it was last shut down. The configuration parameters that are maintained between application launches include window position, shape and the user selected display mode options. The configuration saving capability extends to selected application’s dialog boxes that can be repositioned and reshaped by the user.

Reflectance Profile Mode

This mode gathers and displays a scan reflectance profile for the entire scan path. The profile is displayed with the Reflectance Profile Screen (see

"Reflectance Profile Screen" on page 4-12.) Reflectance Profile Mode is

enabled by clicking the Reflectance Profile Speed button or pressing F3.

Analysis Screens

There are two analysis screens used for setup and monitoring an SV type scanner/verifier. These are the Bar Code Analysis Screen and the Reflectance Profile Screen.

Bar Code Analysis Screen

This screen provides all analysis results for a particular bar code. It also shows many bar code analysis results over time. An example is shown below. Each individual parameter analysis result for one bar code is indicated by a dot on a parameter graph in the Graph Display Area and can be easily accessed via the mouse.

Scanner Setup

Scanner positioning and proper system setup are extremely important for proper SV Series operation. The following sections describe the most common setup possibilities in detail. Some knowledge of SV Series operation is recommended to best follow the steps. Please refer to Appendix A (SV Series Setup Hints -

Scanning Distance and Angle) for a basic description of SV Series operation and

scanner positioning and calibration.

Positioning is important to provide accurate analyses. The scan distance must be set accurately to achieve the proper beam focus to detect printer flaws and failures, such as a worn ribbon (matrix printing), low toner (laser printing), voids (flexo printing), burned pixels (thermal printing). The scan angle is important to accurately measure bar code and substrate reflectance values.

Setup is important to ensure proper interface to print mechanisms and host computers.

Bar Code Travel Direction

Direction

Laser Beam

Ladder Travel Direction

Picket Fence Travel

Bar codes can be scanned in a static location, or more commonly with on-line scanner/verifiers, they can be scanned while moving through the laser beam. The illustration below shows the two directions a bar code can travel through the laser beam. They are designated “picket fence” and “ladder” directions.

The SV unit must be programmed for the direction of travel of the codes being analyzed. If the codes are being scanned in a static condition, use the picket fence travel direction.

Bar Code Travel Speed Considerations

A bar code should be present in the beam for at least five scans for the most reliable operation. The SV Series performs a minimum of 100 scans/analyses per second. At that rate, each analysis is accomplished in 10 milliseconds maximum. Therefore, a bar code must be in the beam for at least 50 milliseconds to be reliably analyzed. Some SV models have higher minimum scans/analysis; therefore a bar code must be in the beam for less amount of time for those models.

SV Scanner/Verifier Setup Procedure

Installation of an SV scanner/verifier requires proper mounting position, output port configuration(s), and LED configurations to ensure the reliable and accurate operation. This section describes the procedures for using ScanView to ensure proper SV setup and installation.

Each SV unit has a label showing the specified mounting distance and angle for its particular scanner. Follow the steps below to ensure the SV unit is properly mounted and programmed.

Quick Check® SV Series User’s Guide 5 - 3

1. Mount the SV units at the proper distance and angle. Use "Good

Reflectance Profile" on page 5-6 as a reference.

2. Connect the power and communication cables to SV unit.

3. Set the SV unit for picket fence bar code travel direction by clicking the Picket Fence Mode item in the ScanView Setup Menu.

4. Place a sample bar code in the center of the intended laser beam path. For best results, this sample should match the type of bar code(s) and material that is to be analyzed in the final application. Knowing the X dimension (narrow element width of the bar code(s) is a big plus as will be seen in Step 5.

Note: SV calibration symbols have a 10 mil X dimension unless otherwise

indicted.

5. Take a Reflectance Profile with ScanView (see "Reflectance Profile

Screen" on page 4-12).

a. Ensure the bar code(s) is in the center of the scan path.

b. Ensure the scan profile contains no distortion from light reflecting

from objects in or near the light path. (An example of a good reflectance profile is provided in the "Reflectance Profile Screen" on

page 4-12.). One major aspect in a good profile is the low reflec-

tance points (the bars) in the symbol are uniform all the way across the code. Optimum signal amplitude should be adjusted so the bar code element reflectances are between the 90% and 10% marks shown in yellow on the screen. Scanner angle has the most effect on the signal amplitude.

c. Continue adjusting the SV unit’s placement until a good, centered

scan profile is obtained. The scan angle may have to be altered slightly or a light shield may have to be installed in extreme cases to achieve a good reflectance profile. If adjustment of scan angle does not produce the correct signal amplitude or placement, see Adjust-

ing Scanner Gain and Offset (page 5-10) to adjust scanner gain and

offset.

6. *Place ScanView in Session Mode.

a. Click on the Report an Analysis Speed button.

b. Ensure that X in the bottom panel of the Bar Code Analysis Screen

matches the X dimension of the symbol within +/- .1 mil.

c. Adjust distance of the SV100 from the bar code until the X dimen-

sion matches the desired value. (If X is analyzed as too large, move the scanner farther away; if X is too small, move the scanner closer.)

7. Repeat steps 4 and 5 until no more mounting adjustments are required.

8. Remove the symbol from the laser beam path.

5 - 4 Quick Check® SV Series User’s Guide

9. Program the SV unit’s ports, LEDs, sync mode, etc. (if required).

10. Calibrate the SV unit if any reflectance parameters (such as symbol contrast) are programmed in this application to report to a host or activate any ports. Each SV unit is supplied with a calibration symbol.

11. The SV scanner/verifier is now ready to operate for picket fence bar code travel direction. If Ladder Mode is being used and the desired scanning length for ladder bar code travel direction is programmed, place the unit in ladder mode. The unit is now ready to operate.

Note: If ladder mode scanning length is to be programmed, continue with the

following steps.

12. Turn off partial decodes using the ~Lp0 command.

13. Display additional results in ScanView through the Advanced Menu.

14. **Place a sample of a bar code that is to be analyzed on the farthest position towards the left end of the laser beam where the code is intended to be scanned.

15. Analyze the code by clicking the ScanView Report an Analysis Speed Button.

16. Confirm the code is being read and analysis results are proper. If not, move the code to the right until acceptable analysis results are achieved.

17. Record the value of the “Hor Pos” value in the additional parameters for the acceptable analysis. This value will consist of four digits. This value will be used for the “Set Ladder Start Position” setting later in the procedure.

18. Move the code to the farthest position towards the right end of the laser beam where the code is intended to be scanned.

19. Similar to steps 15, 16 and 17, obtain an acceptable analysis and record the “Hor Pos” value for the acceptable analysis. This value will be used for the “Set Ladder Stop Position” setting later in the procedure.

20. Place the unit in Ladder mode through the Setup Menu. Place the proper values for the “Set Ladder Start Position” and “Set Ladder Stop Position” boxes during menu process.

21. Enable partial decodes if desired for this application.

22. The unit is now ready to operate for ladder bar code direction.

*This step is not mandatory, but highly recommended. Scanner focus is dependent on the scan distance. Good focus maximizes the SV unit’s ability to detect printer errors and failures. If this step is omitted, take extra precaution in setting and measuring the scan distance.

Picket Fence Direction

In picket fence travel direction, a bar code is in the laser beam throughout the height of the shortest bar in the code. An easy way to estimate the fastest speed the code can travel through the beam is to divide the height of the shortest bar in the code by the maximum time required for the SV unit to take five scans of the code. For example: Calculate the maximum travel speed where the shortest bar height in a code is .5 inches and the SV model being used performs a minimum of 100 scans/analyses per second. Five scans requires 50 milliseconds (.05 seconds) to gather, so .5 inches (bar code height) divided by .05 seconds (time needed to gather 5 scans) = 10 inches/second. Therefore, the maximum speed the code can travel through the beam is 10 inches per second.

Vertical distance between bar codes is also a speed consideration in picket fence direction. The SV Series must have five continuous scans where no bar code is detected to reliably exit a bar code when operating in the standard operation mode set by Command ~HO1. Assuming 100 scans per second minimum, this means the vertical distance between the codes must take at least 50 milliseconds to pass through the laser beam. Calculate the maximum speed by measuring the shortest vertical space between bar codes on a label (or between labels.) Divide this distance by .050 (seconds). The result is the fastest speed the codes can move through the beam. If the application travel speed cannot be met due to a short vertical distance between codes, Command ~HO2 can be used to cause the SV to exit on a change in data rather than detecting no bar code.

Quick Check® SV Series User’s Guide 5 - 7

Note: If using ~HO2, ensure the bar codes with short vertical gap are encoded

with different data and only one code across is being analyzed in each scan.

Note: The slower of the two print speeds calculated above for bar height and

gap height is the maximum recommended speed for picket fence travel.

Picket Fence Bar Code Positioning Specifications:

• Four codes across maximum

• Horizontal gap between codes: .5 inch (13 mm) minimum

• Maximum number of codes per sync period: 99

Ladder Direction

In ladder direction, one bar code at a time is usually in the beam. The amount of time the code is in the beam is a function of the total width of the code (including quiet zone), the length of the beam area that is used for scanning and the speed the code is travelling. The distance the bar code is in the beam is calculated by subtracting the bar code width from the length of the beam programmed to scan the bar code. (See "Setting Ladder Mode Scanning Length Using ScanView

Software" on page 5-8.) Divide this difference by the amount of time the SV

model requires to gather 5 scans to get the maximum speed. For example, a bar code with total width of 3 inches is to be analyzed in a beam length of 6 inches and the SV model being used performs a minimum of 100 scans/analyses per second. Maximum speed of travel is (6 –3)inches /.050 seconds = 60 inches per second in ladder direction.

Setting Ladder Mode Scanning Length Using ScanView Software

The distance and location in the laser beam where a bar code is scanned sometimes must be tuned (programmed) for a particular ladder mode application. In general, the wider the length, the faster the bar codes can travel. In some cases, a narrower scan length is required to mask an adjacent code so only one code at a time is scanned.

Calibration

Calibration is required if any reflectance calculation (e.g., symbol contrast, Rmin, PCS) is used in the application. It is recommended to calibrate the unit in any case during initial setup to ensure the scanning distance and orientation is within device limits. A calibration symbol is supplied with each SV unit as a standard component. Store this symbol in a clean location.

The SV Series can be calibrated using either of the two following procedures:

5 - 8 Quick Check® SV Series User’s Guide

Procedure 1

1. Remove all bar codes from the laser beam path.

2. Place the supplied calibration symbol in the laser beam in the same position (distance and angle) as the labels to be verified will be scanned.

3. Press and hold the RESET button on the SV unit until the Calibration LED begins to flash.

4. Release the RESET button immediately after the Calibration LED begins flashing.

If calibration is successful, the laser beam will go off and the Calibration LED will go off.

5. Remove the calibration symbol from the beam path, and press the RESET button until the beam turns on. The SV unit is now ready to operate.

If calibration is unsuccessful, the Calibration LED will be either on steadily or flashing. In this case, repeat the calibration procedure.

Procedure 2

1. Place the supplied calibration symbol in the laser beam in the same position (distance and angle) as the labels to be verified will be scanned.

2. Send “~SC” into the SV unit serial port. This will cause the Calibration LED to flash.

3. If calibration is successful, the laser beam will go off and the Calibration LED will go off. Remove the calibration symbol from the beam path and then Press the RESET button until the beam turns on. The SV unit is now ready to operate.

4. If calibration is unsuccessful, the Calibration LED will be either on steadily or flashing. In this case, repeat the calibration procedure.

Once calibration is successful, re-calibration is not required unless the unit has been moved – either on its mounting stand or into a new location. It is advised to keep the laser beam exit window clean. Dirt, dust, and fingerprints on the exit window can affect calibration.

Quick Check® SV Series User’s Guide 5 - 9

Adjusting Scanner Gain and Offset

Scanner gain and offset adjustment via commands is available in SV units that have the “A” circled on the label that indicates focus distance. The adjustment capability is useful for adapting the unit to various material types and scanning angles during the setup procedure. Knowledge of Hand Held Products’ ScanView software is required for best understanding of the following description.

When setting SV scanner gain and offset, use ScanView Reflectance Profile Mode as the guide to viewing signal levels. The object is to have at least 6 lines high of signal amplitude for the bar code(s) being verified. The bar code signal vertical placement (offset) should be within the yellow lines to ensure the signal is in the linear range. All other objects’ amplitudes and placements are not important. A picture of a “good” signal level is shown on page 5-11.

To adjust gain and offset settings, first use the ScanView Transmit SV Commands Screen to send a ~HT command to the SV unit. In the reply, look for the line that reads [DACs] = nnn nnn nnn nnn where nnn = numeric values. Example: a unit may read: [DACs] = 201 146 255 255. This indicates the current settings.

1. The 201 indicates the value of the gain setting. The higher the value, the higher the gain and therefore the higher the amplitude of the scan profile for a symbol. Max value is about 225.

2. The 146 value indicates the offset setting. The higher the value, the lower the symbol placement is offset on the graph.

3. The command ~Hd101nnn sets gain where nnn is the three digit value.

4. The command ~Hd201nnn sets offset where nnn is the three digit value.

5. Use these commands to set the desired signal amplitude ( ~Hd101nnn) and locate the signal vertical placement between the yellow lines ( ~Hd201nnn.)

6. A few iterations of commands will probably be needed, therefore it will be necessary to access the Transmit SV Commands Screen and Reflectance Profile Mode alternately.

Note: A short cut to the Reflectance Profile Mode is accessed by pressing F3.

7. Like most other SV commands – new scanner settings are enabled immediately when received, but to be stored to non-volatile memory so they are maintained on a power up condition, the ~Hx command must be transmitted after the desired settings are achieved.

SV Command Language

Introduction

All commands to the verifier begin with a tilde, ‘~’, followed by one or more alphanumeric characters. The ‘~’ identifies the subsequent character string as a verifier command. The string is parsed from left to right. The first character after the ‘~’ identifies the command category. Each command requires at least one additional character that identifies the particular command from that category. Some commands require additional data, e.g., a data value, or an option ID character, or a text string. These values are included at the end of the command string. The command string format is shown below. As each character is received by the SV unit, it echoes back the same character. Echo-back is used to determine when the verifier has completed the command action. The verifier is ready to receive the next command when the last character of the command is transmitted (echoed-back) to the host.

~CPx…

~ - indicates the start of a command string.

C - a character that identifies the command Category

P - a character that specifies the Particular command in the category

x… - a number or text string (as necessary)

Data Match Commands – B

A ‘~’ followed by a ‘B’ specifies a command from the Data Match category. All Data Match commands include a second alphabetic character that identifies the particular diagnostic command. The Data Match Commands are listed below.

An important consideration when using data match type commands is the data format. These commands incorporate a “scanner” philosophy rather than a “verifier” philosophy. A scanner philosophy is to report the data encoded in a symbol while a verifier philosophy is to report all symbol characters whether they include data or not. Symbol characters typically include stop character, start character, symbology mod check digit(s), internal control characters, etc. depending on the symbology type.

The data fields described in the B commands below include data characters only, therefore the ~B commands have a “scanner” philosophy. The one possible exception is in UPC or EAN symbols the symbology mod 10 check digit is also considered a data character.

A data match error occurs if at least one array is active and the data scanned does not match the data programmed in the array. Each array can be up to 32 characters in length. Multiple portions of each array can be masked and the mask character is defined in the command. The data in the array must consist of printable ASCII characters with ASCII values less than 128.

Increment is to be done in location 6 through 8 characters of the 10 character array.

~BD010!!!!!!!+++

~BD110!!!!!!!C34

~BD010!!!!!+++!!

~BI000 or ~BD000

~BU#

Allows data match command ~BC to detect a Code 128 Function 1 character.

This allows a check to make sure function 1 characters (F1) are correctly placed in applications involving GS1-128 symbols. # = 0 or 1.

If ~BU0 is set - the ~BC command acts "normal" per the ~BC command description.

Decrement is to be done in the last three characters of the 10 character array.

Decrement is to be done in the last three characters of the 10 character array. The initial value scanned must be C34 (base 36 alphanumeric field).

Decrement is to be done in location 6 through 8 characters of the 10 character array.

Disable the Increment/Decrement array. The remainder of the array data is not required.

6 - 4 Quick Check® SV Series User’s Guide

If ~BU1 set, if a right bracket character ( ] ) character is set in the ~BC command data field, that will be used as a match for a Code 128 F1 character.

The F1 character will be treated as a data character rather than a symbol character and therefore be included in the data match logic.

This also means that even if the special character is not included in the ~BC command, but ~BU1 is set, an F1 character in the symbol will still be checked as a data character, therefore any extra F1 character will cause a data match error.

Note: If ~OS1 is set, and ~BU1 is set, right bracket characters are stripped from

the transmitted data. Therefore this application is not suitable when mixing GS1-128 codes and normal Code 128 codes that contain a right bracket character. Setting ~OS0 for all symbol characters in the transmission operates normally with either setting of ~BU#.

Relationship Between ~BC and ~Br Commands

When programming both data match and increment/decrement arrays, the data match array(s) have higher priority. This is useful when analyzing a label containing more than one bar code, and one of the codes contains an incrementing or decrementing field. In this case, a data match array(s) can be used to match (or in this case – logically “mask”) the bar code(s) containing static data and the increment/decrement array can analyze the incrementing or decrementing bar code data.

~ BT

Lists all Data Match strings and Increment/Decrement fields.

~Hdx01nnn

Sets scanner gain or offset.

x = value of 1 or 2. If =1, scanner gain is set. If = 2, scanner offset is set.

nnn = gain or offset setting.

For gain, the higher the value, the higher the gain. 225 is the max allowed value.

Example: ~Hd101195 sets the scanner gain setting to a value of 195.

For offset, the higher the value, the lower the offset.

Example: ~Hd201145 sets the scanner offset value to 145.

These commands are best used in conjunction with Hand Held Products’ ScanView software. Please refer to Chapter 4 for descriptions on the use of these commands.

~Hnx

Sets the number of consecutive scans that do not detect a bar code that cause a bar code to exit the beam and be reported.

x = values of 2, 3, 4 or 5. The normal setting is 5.

This command is best used in conjunction with the ~SB 1 setting for single scan operation. Please see ~SBn (page 6-24) command description.

~Hx

Saves the parameters to FLASH (non-volatile memory) from RAM.

6 - 10 Quick Check® SV Series User’s Guide

~H#nn

Sets the number of signal transitions to search for finding a bar code symbol

nn = values of 10 through 99. This indicates the number of high to low transitions of the optical signal to search before ending a search for a bar code. High values of nn are useful when complex graphic fields or small fonts are closely adjacent to a bar code and therefore in the scan path. The higher the number, however, the greater chance the analysis rate will be lowered. For normal situations with minimum graphics in the same path as the bar code, a value of 10 is recommended (~H#10.)

Label Setup Commands – L

A ‘~’ followed by an ‘L’ specifies a command from the Label Setup category. The next character identifies the particular Label Setup Command. In general, the commands in this category terminate with one or more numeric digits. The Label Setup Commands are listed below.

~LA##

Overall passing grade.

## is the numeric grade value – 00 through 40. Example ~LA32 causes an ISO Overall Symbol Grade of 3.1 or lower to set a failure condition.

~LC##

Minimum number of symbol characters to decode in an Interleaved 2 of 5 symbol.

This command sets the minimum number of symbol characters to be expected (## in the command, 01-16) by the Interleaved 2 of 5 decoder. This adds extra filtering in applications where I 2 of 5 symbols are used and there is a large amount of other graphics, such as fonts in the scan path. Example: ~LC03 sets the unit to decode I 2 of 5 symbols (assuming the I 2 of 5 decoder is enabled) containing three or more symbol characters.

Note: Each I 2 of 5 symbol character contains two data digits, therefore the

symbol in the example must contain a minimum of six data digits to be decoded.

~LD##

Passing percent decode.

This command sets the % decode threshold for a passing condition. If analyzing poorly printed symbols, it is recommended that partial decodes be enabled at the decoder level when this command is enabled.

xx = failure threshold. Example ~LD75: if 74 % or less of scans on a code were not fully decoded, this sets a failure for this parameter.

~LN##

Set Minimum Number of Bar Codes Per Label (i.e., per sync period)

This command instructs the verifier on how many bar codes it is expected to read and analyze during a sync period. If the programmed number of codes are not read, a (robust) NO READ condition is internally flagged for communications or output port activation. Except for mode ~LV03, this command sets the minimum bar codes expected. Mode ~LV03 uses this value for the EXACT number of codes read during the sync interval.

~LR#

Enable or Disable No Read Transmission or Alternate Data Transmission Formats

A No Read transmission message can be sent via the serial port if the SV unit is receiving sync inputs. See "Serial Port Transmission Format" on page 3-1 for details. Fields y, M and N (data positions 52 through 55) set to 0, indicate a No Read condition.

Values for # are:

1 enables the No Read message to be transmitted

0 disables the No Read transmission

The transmission is available in any output interface mode that includes a no read condition. The transmission data format enabled (~OS#) does not affect the format of the No Read transmission.

Alternate data formats can also be transmitted using the ~LR# command.

# = 2, disables all data transmissions. The exceptions are ~SA and ~SY will cause a "normal" transmission if a bar code is in the laser beam when the command is received. This allows bar codes to be reported to ScanView during setup. A No Read transmission is not available with this setting.

# = 3, causes the SV unit to transmit bar code data only without the 88 byte field used to indicate all quality parameters. The data has no framing. The data format is determined by the state of the ~OS# command (data or all symbol characters). ~SA and ~SY will cause a "normal" transmission including the 88 byte field of verification analyses if a bar code is in the laser beam when the command is received. This allows bar codes to be reported to ScanView during setup. A No Read transmission is not available with this setting.

# = 4, is identical to ~LR3 with the exception that after the data characters a carriage return character is transmitted followed by a line feed character.

# = 5, is similar to ~LR3 in that it causes the SV Unit to transmit bar code data only in the format set by the ~OS# command. The data is framed by characters set by the ~SSbbbeee command. Commands ~SA and ~SY will allow transmission of the "normal" format including the 88 byte field of verification analyses, but the transmission will also be framed with the characters set by the ~SSbbbeee command. Therefore it may not be compatible with setup with ScanView. A No Read transmission is not available with this setting.

Quick Check® SV Series User’s Guide 6 - 15

# = 6, causes the SV unit to transmit bar code data only, without the 88 byte field used to indicate all quality parameters. The data has no framing. The data format is determined by the state of the ~OS# command (data or all symbol characters). ~SA and ~SY will cause a "normal" transmission including the 88 byte field of verification analyses if a bar code is in the laser beam when the command is received. This allows bar codes to be reported to ScanView during setup. With this setting, a No Read transmits the string "No Read" instead of the No Read analysis record.

# = 7, is identical to ~LR3 with the exception that after the data characters a carriage return character is transmitted followed by a line feed character. With this setting, a No Read transmits the string "No Read" instead of the No Read analysis record.

# = 8, is similar to ~LR3 in that it causes the SV Unit to transmit bar code data only in the format set by the ~OS# command. The data is framed by characters set by the ~SSbbbeee command. Commands ~SA and ~SY will allow transmission of the "normal" format including the 88 byte field of verification analyses, but the transmission will also be framed with the characters set by the ~SSbbbeee command. Therefore, it may not be compatible in setup with ScanView. With this setting, a No Read transmits the string "No Read" instead of the No Read analysis record.

~LS##

Set minimum number of scans for valid read

## = 02 – 99 (See ~SBn (page 6-24) command for ##=01; single scan mode)

This command sets the minimum number of times a full decode must be achieved on a symbol in order to be a valid read. The system acts slightly differently, depending on what operation mode is set – ~HO1 or ~HO2.

With ~HO1 enabled, if the minimum number of full decodes is not accomplished, a No Read condition is set, even though the bar code is read, analyzed and reported. The report includes a No read status indication. With ~HO2 enabled, if the minimum number of full decodes is not accomplished, the code is not recognized nor reported. This essentially creates a No Read condition when a sync input is being received.

When used in conjunction with the ~LDxx command, the ~LS## command can create a powerful area check of a symbol.

System Control Commands – S

A ‘~’ followed by an ‘S’ specifies a command from the System Control category. These commands include one additional character that identifies the particular System Control Command. The System Control Commands are listed below.

~SA

Software sync for communication output mode #4 – Commanded Read Mode ( ~HO4)

~SBn

Normal or Single Scan Operation

When n=0, normal scanning is enabled where a code must be scanned 2 out of 3 times in order to be detected.

When n=1, a single scan of can be used to capture and analyze a bar code, enabling bar codes to be analyzed while traveling through the laser beam at high speeds.

6 - 24 Quick Check® SV Series User’s Guide

The major trade-off to the single scan feature is only one bar code at a time can be analyzed in the beam vs. up to 4 codes in picket fence mode in the standard system. The major disadvantage to this method in cases where only a single scan is used for evaluation of a bar code is there is a higher probability that the analyses may not be accurate because part of the scan could be at the upper or lower edges of one or more of the elements in the code. Therefore if most of the analyses are being calculated with a single scan, this type of operation is recommended for measuring print trends in high volume, high speed applications where some small percentage of analyses that randomly indicate an unusual low grade can be filtered out.

In the case the bar code is in the laser beam for more than a single scan, all the scans gathered are averaged in the symbol analysis just like standard SV operation.

The special single scan operation is enabled only in Ladder Orientation mode. Picket fence Orientation mode operation is not affected. The travel direction of the codes can be either picket fence or ladder. The reason for using ladder mode is it limits the number of codes that can be simultaneously analyzed in the beam to a single code.

How to Set Up Single Scan Operation

Three commands that set up the operation are ~SB1 and ~LS01 and ~Hnx (x can be 2, 3, 4, or 5). The SV must also be placed in "Ladder" mode and the code must be in the ladder zone to be scanned and analyzed.

~SB 1 (~SB0 is the normal setting) enables the system to let the initial scan of a code pass to the analysis algorithms rather than wait for one of the next two scans to be a duplicate before the code is allowed to be analyzed.

Note: The ~SB1 setting may not update the horizontal bar code position in the

report transmission. Therefore if the horizontal position is needed during setup, set ~SB0 temporarily to see the position, then set ~SB 1 for 1 scan operation.

~LS01 allows the initial scan to be reported as a 1 scan average in case the code leaves the beam before a second scan is detected.

~Hnx is a command that programs the number of consecutive scans that do not detect a bar code that cause the code to exit the beam and be reported. The standard system operation is fixed at 5. ~Hnx can be programmed for 2, 3, 4, or 5 scans. A lower number will allow a higher duty cycle, but it may also be less stable if a code is static in the laser beam, therefore causing multiple reports.

Note: Especially when setting up with a static code in the beam, or operating in

picket fence orientation, make sure the code passes through the programmed ladder zone.

Checking SV Status with ~HT

The normal way of checking system status is with the ~HT command. The newer commands ~SB and ~Hn are not displayed with the standard ~HT command. In order to display the additional commands, set command ~De1 to allow the alternate ~HT reply.

Quick Check® SV Series User’s Guide 6 - 25

When using ScanView menus to program SV parameters, set ~De0 for normal ~HT reply or an error message may be displayed.

~SC

Execute the calibration procedure.

The SV unit responds to this command as follows:

CP505050 is transmitted if the calibration is successful.

CF000000 is transmitted if the calibration was unsuccessful

~Sc (lowercase c)

Set Scanner Gain and Offset for symbol that is in the laser beam

This command automatically sets the scanner gain and offset to a bar code that is in the laser beam. Place the SV unit in moving codes mode to use this command. In some cases where more than two reflectance levels are in the beam (caused by color graphics, etc.), this command will be unsuccessful. In those instances, use the ~Hd commands to set scanner gain and offset.

~SD

Disable Verification

This command turns the laser beam off.

~SE

Enable Verification

This command turns the laser beam on.

~SK#

Communication Sync

A sync command sent via serial communications can be used similar to an external sync input to analyze a no read condition. In previous versions of SV firmware the only way to create a no read transmission or no read control output from an SV unit is by detecting an external sync through inputs on pin 1,2 (Isolated) or on pin 4 (ttl) of the Power I/O connector.

# = 0 or 1. Details of how the values are used in conjunction with other commands as follows:

1. Command ~LT# includes an ~LT2 choice to allow ~SK# as the sync input

2. ~SK# will be received but not cause any action if either ~LT0 or ~LT1 is set.

3. An external sync input will not be recognized if ~LT2 is set

6 - 26 Quick Check® SV Series User’s Guide

4. Receipt of ~SK# command will be identical to detecting a hardware sync input

5. After receiving the ~SK# command, the SV unit will operate per settings of the various commands related to sync inputs - ~LR#, ~LV#

6. ~LP0 must be set when using any Output Interface Mode except 2 and 19

7. ~LP1 must be set if using Output Interface Mode 2 or 19

8. ~LX0, ~LX1, ~LX2 or ~LX3 can be used with any Output Interface Mode except 2 and 19

9. ~LX0 must be set if using Output Interface Modes 2 or 19

Operation Description

1. If ~LX0 or ~LX2 (any envelope sync mode) is enabled

a. Receipt of ~SK1 will be the leading edge of the envelope sync

b. The end of the envelope sync will occur when~SK0 is received

c. After ~SK1 is received, any additional ~SK1 received will be ignored until

a ~SK0 is received

d. After ~SK0 is received, any additional ~SK0 will be ignored until an ~SK1

is received

2. If ~LX1 or ~LX3 (any edge sync mode) is enabled

a. Receipt of any ~SK0 will be ignored

b. Receipt of any ~SK1 will be the edge sync input

Note: Recognition and response of the communication sync commands may be

slower than a hardware sync (13 ms).

~SN###

Set the number of scans for Software Commanded Read Mode.

### - The number of scans up to 200.

~SQ

Raster Check.

This command shows beams for all eight polygon facets for 4 seconds, then shows a beam for one facet for 4 seconds. Ideally, the beam widths will look identical in non-raster type scanners. Acceptable difference in most cases is 1/

~SR

Reset the System.

This re-initialization procedure recalls all of the current setup parameters from the flash.

~SSbbbeee

Program the start and end characters in a transmission

bbb = decimal value of the ASCII character that indicates the beginning of a transmission. eee = decimal value of the ASCII character that indicates the end of a transmission. Allowed values for bbb and eee are 001 through 127.

Example ~SS083069 causes an S to be the beginning character and an E to be the ending character of a data transmission. This command applies only when the standard transmission mode is enabled (~HQ0.) The command ~SS013010

must be used when operating with RJS ScanView software.

~SY

Software Sync for communication output modes #1 and #2 (~HO1, ~HO2); trigger a sync response from the verifier, and enable the verifier

~Sh##

Set the high target reflectance value for calibration.

## - The high target reflectance value (70 to 99).

This sets a new high reflectance target value for a calibration symbol.

To use the target values encoded in the calibration symbol set this value to 00.

~Sl##

Set the low target reflectance value for calibration.

## - The low target reflectance value (1 to 20).

This sets a new low reflectance target value for a calibration symbol.

To use the target values encoded in the calibration symbol set this value to 00.

~Ssxy

Program header and trailer characters in a standard transmission format.

This command is similar to ~SS, but allows a programmable number of characters that begin and end the standard transmission, where ~SS has a fixed single character for both start and end of the transmission.

x = number of characters in the header. Allowed values are 0,1,…9 therefore up to nine header characters are available.

6 - 28 Quick Check® SV Series User’s Guide

y = number of characters in the trailer. Allowed values are 0,1,2 therefore up to two trailer characters are available.

If either x or y are not 0, then additional 3 digit fields indicating the decimal value of the ASCII character transmitted must be added to the command for each character placement indicated by the x and y settings. Allowed values are 001 through 255.

If both x and y are 0, then the ~SS command settings are used for header and trailer characters.

The ~Ssxy command is basically an override to the ~SS command and obeys all current logic involving the ~SS command in conjunction with other command settings. Therefore ~LR0 or ~LR1 must be set for the transmission format to be valid for all transmissions.

Any other values of ~LR override the transmission format with the format defined by that particular ~LR setting.

Data Transmission Example 1

If ~Ss00 is set, ~LR3 is set and SV is in moving codes mode, if ~SY is received the transmission format sent will be sent according to the ~SS command settings.

Data Transmission Example 2

If ~Ssxy is programmed so x or y does not equal zero, in the case of Data Transmisssion Example 1 above, the transmission format will be sent according to the ~Ssxy command setting.

~S sxy Command Example 1;

~Ss320480491 12013010

~Ss = the command header

x = 3 which means there will be three header characters transmitted

y = 2 which means there will be 2 trailer characters transmitted

048 = decimal value for ASCII character 0 which will be the first header character transmitted

049 = decimal value of ASCII character 1 which will be the second header character sent

112 = decimal value for ASCII character p which will be the third header character (and final) sent

013 = decimal value for ASCII character CR which will be the first trailer character sent

010 = decimal value of ASCII character LF which will be second (and final) trailer character sent

~Ssxy Command Example 2;

~Ss11080086

One header character P will be sent and one trailer character V will be sent

~Stx

Program Command Indicator Header

This command programs the indicator character from a pre-determined set of available characters.

x - the value of this character is used for selecting the command indicator. Available indicators are ASCII characters that are not part of any standard SV command syntax in order to be secure. Allowed values of x are 0,1, ..9. Indicator characters available are below;

~St0 = ~ (system default) ASCII decimal value of 126

~St1 = : ASCII decimal value of 58

~St2 = ; ASCII decimal value of 59

~St3 = ( ASCII decimal value of 40

~St4 = ) ASCII decimal value of 41

~St5 = [ ASCII decimal value of 91

~St6 = ] ASCII decimal value of 93

~St7 = { ASCII decimal value of 123

~St8 = } ASCII decimal value of 125

~St9 = ^ ASCII decimal value of 94

Valid command syntax is [LV00 instead of the default ~LV00

Output Interface Modes Descriptions

Output interface modes are used to set the SV Series for particular ways to activate output ports. The mode is set via the ~LV## command. The following list describes the standard output interface modes available in SV firmware versions x270 and higher. Each description includes the commands for programming the particular parameters that can activate the proper ports for that mode. Custom modes are available – contact Hand Held Products Technical Support.

After programming the SV unit for the desired port activation parameters, it is recommended that you review them. When using ScanView, this can be done via the Transmit SV Commands Window by sending the ~HT command to review all scanner settings and sending the ~PT8 command to review all quality parameter failure threshold settings.

SV Commands Important to Mode 01

This system is operating in a “mode” rather than fully programmable logic. The port activation parameters are programmable via the ~PB8 rather than ~PB1, ~PB2, etc. for each individual port. Other commands, such as mode commands are also available. The commands most useful for this system application are described below.

~LV01

This command sets this mode of operation.

~Lp0

This command turns off all partial decode logic at the decoder level

~Lp1

This command turns on partial decode logic at the decoder level

~LQ1

This command allows partial decodes to activate the output ports

~LQ0

This command disables partial decodes to activate output ports.

Note: In SV firmware versions x238 and lower, ~LQ commands are not

implemented and the command ~HQ1 must be used to disable partial decodes from activating ports. In this case the standard data transmission format is modified, and ScanView will not display data characters correctly.

~LDxx

This command sets the % decode threshold for a passing condition. If analyzing poorly printed symbols, it is recommended that partial decodes be enabled at the decoder level when this command is enabled.

xx = failure threshold. Example ~LD75: if 74% or less of scans on a code were not fully decoded, this sets a failure for this parameter.

~PB816xxx100

This command sets the minimum percent of scans on a code which calculate good quiet zones to determine an acceptable quiet zone analysis. The field xxx is the minimum passing threshold. Example: if xxx = 030, a minimum of 30% of all fully decoded scans on a code must calculate a good quiet zone, or a failure condition is set for this parameter.

~PB806xxx000

This command sets the threshold for the ISO Defects calculation on a code to set a failure condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 025, a Defects analysis of 26% or higher will cause a failure condition for this parameter.

6 - 32 Quick Check® SV Series User’s Guide

~PB802xxx100

This command sets the threshold for the ISO Decodability calculation on a code to set a failure condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 037, a Decodability analysis of 36% or lower will cause a failure condition for this parameter.

~PB804xxx100

This command sets the threshold for the ISO Symbol Contrast calculation on a code to set a failure condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 020, a Symbol Contrast analysis of 19% or lower will cause a failure condition for this parameter.

~LN##

This command sets the minimum number of codes to be read during a sync period. ## = the number of codes. For example: ~LN02 causes a No Read condition to be set if less than 2 bar codes are fully decoded during a sync interval.

~LZ##

This command sets the exact number of codes to be read during a sync period. ## = the number of codes. For example: ~LZ02 causes a No Read condition to be set if exactly 2 bar codes are not fully decoded during a sync interval.

This command overrides the ~LN## command if the number of codes set does not = 00. If ~LZ## is set to ~LZ00, the ~LN## command takes precedence.

~LAxx

This command sets the passing threshold for the Overall ISO method Symbol Grade. For example: ~LA28 causes an Overall Symbol Grade of 2.7 or lower calculated for the code analyzed to set a failure condition for this parameter.

~Hx

This command stores all parameters into non-volatile memory. This command should be the last command sent after parameters are programmed via the above commands.

Mode 02 (~LV02)

Mode 02 I/O operation

1. Envelope type sync input on pin 4

2. Port 3: per sync type. The state of this output must be stable within 12.5 milliseconds after the sync input goes low (trailing edge.) Typical time for stability will be less than 7.5 milliseconds if the sync is received when a bar code or complex graphic is not in the beam. The port shall go active (sink current) for the following conditions;

e. No Read (if sync is received)

f. Partial decodes and % decode logic programmable (~Lp#, ~Lq#)

g. Number of codes per sync programmable (~LN##, ~LZ##)

h. Symbology modulo check digit

3. Sync polarity - Leading edge high going; time between trailing (low going) edge to leading edge - 12.5 milliseconds minimum

4. Port 1; acts as strobe (signal ensuring Port 3 condition is stable) in response to trailing edge of sync input. This signal will go “on” (sink current) between 20 and 100 microseconds after Port 3 condition is stable.

5. Ports 1 and 3 will go high (no current) within 12.5 milliseconds after the sync input goes high (leading edge).

6. Use ~PR0200 for proper port initialization.

Mode 02 LED Operation

1. LED1 will turn on if Port 3 goes active due to ISO or quiet zone failures

2. LED2 will turn on if Port 3 goes active due to a no read or partial condition

SV Commands Important to Mode 16

This system is operating in a “mode” rather than fully programmable logic. The port activation parameters are programmable via the ~PB8 rather than ~PB1, ~PB2, etc. for each individual port. Other commands, such as mode commands are also available. The commands most useful for this system application are described below.

~LV16

This command sets the proper mode for this operation.

~Lp0

This command turns off all partial decode logic at the decoder level

~Lp1

This command turns on partial decode logic at the decoder level

~LQ1

This command allows partial decodes to activate the output ports

~LQ0

This command disables partial decodes to activate output ports.

~PP801xxx

This command sets the “active” time for the port pulses. The value “xxx” sets the time in .1 second intervals. Any value greater than 100 (10 seconds) creates a latching output.

~LDxx

This command sets the % decode threshold for a passing condition. If analyzing poorly printed symbols, it is recommended that partial decodes be enabled at the decoder level when this command is enabled.

xx = failure threshold. Example ~LD75: if 74 % or less of scans on a code were not fully decoded, this sets a failure for this parameter.

6 - 40 Quick Check® SV Series User’s Guide

~PB816xxx100

This command sets the minimum percent of scans on a code which calculate good quiet zones to determine an acceptable quiet zone analysis. The field xxx is the minimum passing threshold. Example: if xxx = 030, a minimum of 30% of all fully decoded scans on a code must calculate a good quiet zone, or a failure condition is set for this parameter.

~PB806xxx000

This command sets the threshold for the ISO Defects calculation on a code to set a failure condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 025, a Defects analysis of 26% or higher will cause a failure condition for this parameter.

~PB802xxx100

This command sets the threshold for the ISO Decodability calculation on a code to set a failure condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 037, a Decodability analysis of 36% or lower will cause a failure condition for this parameter.

~PB804xxx100

This command sets the threshold for the ISO Symbol Contrast calculation on a code to set a failure condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 020, a Symbol Contrast analysis of 19% or lower will cause a failure condition for this parameter.

~PB811xxxyyy

This command sets the threshold for acceptable X dimension ranges. The value for xxx is the narrowest acceptable X dimension. The value yyy is the widest acceptable X dimension. Units are in .001 inch (mils). For example: ~PB811010020 will cause a failure for n X dimension less than 10 mils or greater than 20 mils.

~LAxx

This command sets the passing threshold for the Overall ISO method Symbol Grade. For example: ~LA28 causes an Overall Symbol Grade of 2.7 or lower calculated for the code analyzed to set a failure condition for this parameter.

~LN##

This command sets the minimum number of codes to be read during a sync period. ## = the number of codes. For example: ~LN02 causes a No Read condition to be set if less than 2 bar codes are fully decoded during a sync interval. (This system is using edge sync mode, therefore a sync interval is the time between sync inputs.)

~LZ##

This command sets the exact number of codes to be read during a sync period. ## = the number of codes. For example: ~LZ02 causes a No Read condition to be set if exactly 2 bar codes are not fully decoded during a sync interval.

This command overrides the ~LN## command if the number of codes set does not = 00. If ~LZ## is set to ~LZ00, the ~LN## command takes precedence.
