INTRODUCTION
The PRINTRONIX SV 2 Series of Scanner/Verifiers is designed to be a universal system component that
can analyze linear bar code print quality, check encoded data and detect 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 2 Series unique.
The SV 2 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 enables an SV unit to be an economical Quality
Assurance tool for practically any bar code printing, applying or conveying system.
The SV 2 Series performs practically every accepted method of bar code verification – ANSI 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, therefore accountability for all bar codes printed 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 2 Series is available in different models. All models operate identically, except the scanner
parameters such as scans per second and focus distance are different. Below is a matrix describing standard
available models.

The recommended setup tool for the SV 2 Series is PRINTRONIX ScanVision 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 at no charge from PRINTRONIX and authorized PRINTRONIX re-
sellers. ScanVision can be used to program the SV 2 Series via serial communication using SV Download
language. The language is described in this Operator’s Guide.
LASER BEAM
The laser beam may be on at any time the Power/Sync LED is illuminated.
