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.

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.

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.

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.

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.
Select Graphs
This item allows the user to select which bar code analysis parameter graphs are
displayed on the Bar Code Analysis Screen (see "Bar Code Analysis Screen" on
page 4-9.)

Select Symbologies
This item allows the user to program the SV unit to enable/disable individual
symbology decoders. This is useful for either more secure decoding or
sometimes faster throughput if a single symbology type is always being
analyzed.
Select Com Port
This item allows the user to select a com port in the host PC.
Change Verifier Baud Rate
This item allows the user to program the SV scanner/verifier baud rate.
Match Verifier Baud Rate
This item detects the baud rate of an SV scanner/verifier; then it changes the
ScanView baud rate setting to the detected value. This is useful when using
ScanView as a diagnostic tool in a system that is using the SV communication
interface. ScanView can easily be inserted in the system without re-programming
the SV serial port, therefore when re-connecting the SV unit back to the host, all
communication parameters remain compatible with the host.
Static Codes Mode
This item allows the user to set the SV unit in static codes mode.
Moving Codes Mode
This item allows the user to set the SV unit in moving codes mode.
Data Match
This item opens a dialog box that lets the user configure the Data Match feature.
Minimum Codes Per Sync
This item allows the user to program the minimum number of bar codes expected
in a sync interval. This parameter is important for detecting No Read conditions
when a sync input is being used.
Ladder Mode and Picket Fence Mode
These items allow the user to program the SV unit to scan bar codes traveling in
either “picket fence” or “ladder” direction. “Picket fence” orientation is defined as
the bar code traveling through the laser beam in the direction of the height of its
bars. “Ladder” orientation is defined as the bar code traveling through the laser
beam in the direction of the beam path.
4 - 4 Quick Check® SV Series User’s Guide
Note: In cases where the SV is scanning stationary bar codes, the “picket fence”
direction must be used.
Advanced Menu
This menu is an extension of the Setup Menu, providing less commonly used, but
useful SV system features.
Toggle Display Updating
This item enables/disables display updates in real time. Disallowing updates is
useful to allow ScanView to keep up with a high throughput application.
Toggle Additional Results
This item enables/disables additional analysis parameters to be displayed on the
Bottom Panel of the Bar Code Analysis Screen. The additional parameters are
intended for debug use only while working with Hand Held Products’ Technical
Support.
Download New Firmware
This item is used for updating the firmware revision level in an SV scanner/
verifier.
Port Configuration
This item lets the user configure the SV unit output port activation threshold
settings.
Initialize the Com Port
In the unlikely event that some failure causes the Com Port to lock up, this
feature can be used to unlock the port.
Support Menu
This menu provides special diagnostic displays that are intended to be used only
while working with Hand Held Products’ Application Support.
About (Menu Item)
This item lists information about the origin of ScanView, the version number of
this copy (it also queries the SV unit for its firmware version number) and it shows
the copyright warning.
