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.

Contact Hand Held Products Technical Support for information on custom and
other models.
ScanView Software
The recommended setup tool for the SV Series is Hand Held Products’
ScanView Windows®-based software. This program makes SV setup simple via
menus, plus it offers real time monitoring of bar codes being analyzed. This
program is available from Hand Held Products and authorized Hand Held
Products re-sellers. ScanView can be used to program the SV Series via serial
communication using SV download language. The language is described in this
user’s guide.

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:
1 - Isolated synchronization input (+)
2 - Isolated synchronization input (-)
3 - GND
4 - Switch synchronization input

+ 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.

Quick Check® SV Series User’s Guide 2 - 3
Sync inputs are also available via serial communications. See ~SK# (page 6-26)
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.

Edge Sync Mode
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.
Sync sensed here
Sync period starts here
Sync period ends here

Quick Check® SV Series User’s Guide 2 - 5
3. Counting ceases upon receipt of the trailing edge of a sync signal. The SV
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.

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.
