SAFETY PRECAUTIONS
LASER SAFETY
The following information is provided to comply with the rules imposed by
international regulatory agencies and to instruct you on the proper use of the
LazerData 12000 Series Bar Code Scanner.
Standard Regulations
This scanner utilizes a low-power laser diode. Although staring directly at the laser
beam momentarily causes no known biological damage, avoid staring at the beam
as one would with any very strong light source, such as the sun. Prevent the laser
beam from hitting the eye of any observer, even if the beam is reflected from
surfaces such as mirrors, etc.
This product conforms to the applicable requirements of both IEC 825-1 and
CDRH 21 CFR 1040 at the date of manufacture. The scanner is classified as a
Class 2 laser product according to IEC 825-1 regulations and as a Class II laser
product according to CDRH regulations.
There is a built-in safety device that allows the laser to be switched on only if the
motor is rotating above the minimum threshold for its correct scanning speed.
The laser beam can also be switched off through a software command (see “Beam
Shutter” in the LDHOST Help Online).
WARNING
Use of controls or adjustments or performance of
procedures other than those specified herein may result
in exposure to hazardous visible laser light.

viii
The laser light is visible to the human eye and is emitted from the window on the
front of the scanner (Figures A and B, 10 ). Warning labels (Figure C), instructing
you to prevent laser light exposure to your eyes and informing you of the laser
device classification, are applied to the body of the scanner (Figures A and B, 7
and 8).

General Features - 1.1
1GENERAL FEATURES
1.1 INTRODUCTION
The LazerData 12000 Scanner is a bar code reader complete with decoder. It is
available in 16 standard models that were designed to satisfy the most demanding
requirements of high performance scanning.
Standard Application Program
A Standard Application Program is factory-loaded onto the LazerData 12000
Scanner. This program controls bar code reading, serial port interfacing, data
formatting, and many other operating and control parameters.
The scanner is completely user-configurable from a host computer using the
LDHOST interface utility program provided on diskette with the scanner or using
the Host Mode programming procedure – by ESC sequences via the serial interface.
There are four different programmable operating modes to suit various bar code
reading system requirements. One is the test mode that is used to verify the reading
features and exact positioning of the scanner without the need for external tools.
C Programmability
The LazerData 12000 Scanner belongs to the generation of PSC Automation
scanners that operate under the 'C' programming environment, a recognized
industry standard.
If your requirements are not met by the Standard Application Program, then
Custom Application Programs can be developed by your local PSC Automation,
Inc. distributor.

LazerData®12000 Scanner Installation Manual
1.2 - General Features
1.2 DESCRIPTION
Some of the main features of this scanner are –
•very high scanning speed (800 scans/s)
•raster version availability
•total configurability from host computer
•two serial communication interfaces: one can be set as RS232, RS485, or
20-mA C.L.; the other, an RS232 auxiliary interface
•readability of all popular codes
•supply voltage range from 10 to 30 VDC
•test mode – to verify the reading features and exact positioning of the scanner
without the need for external tools.
•configurability in different operating modes – to suit the most varied bar code
reading system requirements.
•code verifier
•detection capability for absolute label position in the scan line [for digital signal
processing (DSP) models only, see section 1.3]
•Print contrast signal (PCS) verification (for DSP models only, see section 1.3)
The LazerData 12000 Scanner uses a solid-state laser diode as a light source. The
light emitted has a wavelength of between 630 and 680 nm. Refer to the section
"Safety Precautions" at the beginning of this manual for information on laser
safety.
The use of a semiconductor laser has made it possible to develop an extremely
compact scanner with low power consumption. The reader is contained in a rugged
aluminum housing; the physical dimensions are 101 x 83.5 x 42 mm (4 x 3.3 x
1.7 inches) and it weighs about 800 g (1.8 lbs.).
The protection class of the enclosure is IP65. The reader, therefore, is particularly
suitable for industrial environments where protection against harsh external
conditions is required.

Installation Manual LazerData®12000 Scanner
General Features - 1.3
Electrical connection is provided through a cable on the side of the reader. This
cable is terminated with a 25-pin connector (25-pin connector models, see section
1.3, Figure A, 1) or by a junction box (junction box models, see section 1.3,
Figure B, 1).
The laser beam output window (Figure A, 10 ) is on the right-hand side of the
scanner. A green LED on the same side indicates the laser is active (Figure A, 9).
A built-in safety system allows the laser to turn on only after the motor has reached
the correct rotational speed. The laser beam is therefore generated after a slight
delay from scanner power up.
The four LEDs on the left-hand side of the scanner indicate the following:
POWER ON red – (Figure A, 3) indicates the reader is connected to the
power supply
GOOD READ red – (Figure A, 4) is used to signal successful bar code
decoding. It is also used in Test mode to signal the decoding
percentage (for details refer to the section "Test Mode" in the
LDHOST Help Online)
EXT TRIG yellow – (Figure A, 5) indicates the code presence sensor is
active (for details refer to the section "On Line Mode" in the
LDHOST Help Online)
TX DATA green – (Figure A, 6) indicates data transmission on the main
serial output line
The screw holes (Figure A, 2) on the body of the reader are for physical
attachment. The screw holes shown in Figure A,
11
are for the attachment of
accessories, such as the optional 90° mirror.
