Preface
This PS306 is the continuation of the excellent optical design experience
and with a new back-end design, to create an outstanding product
performance and reliability. This scanner features high inerrability, flexibility,
scanning, and decoding capability. It is ideally suited for supermarkets,
pharmacies, petrol stations, and other similar retail stores.
Based on the standard product reliability, the product design concept is fully
focused on user’s context and mode. It also reduces time and cost.
Our solutions provide instant and accurate scanning, making the checkout
process more efficient for you and more convenient for your customers.
Reduce checkout lines at busy times, including weekends and holidays.
Create additional points-of-sale anywhere in the store by enabling
sales associates to access POS systems in real-time and complete
transactions on the store floor.
True presentation scanning, with Omni-directional and pass through
scan capabilities offer a faster, more natural way of working
This scanner reads all popular bar code symbologies, and supports a wide
range of scan pattern. In addition, this scanner also provides an aggressive
first-pass scanning, reducing the time it takes to scan products, increasing
customer satisfaction and employee efficiency. Another important feature of
this scanner is its programmable sleep mode which is designed to save
power on this scanner. If the scanner is not used within a programmable
period of time, the scanner switches off automatically. The scanner can be
re-activated by pressing the sleep mode button.
This scanner is available in two colour versions, both supporting multiple
interfaces for communication with any host system. The multiple interface
versions are: RS-232 + USB + P-USB + Keyboard Wedge(Option).
This manual contains two chapters and three appendices. The first chapter
describes this scanner and its general features. The description for
installation can be found in the second chapter. Precisely follow the
instructions for the installation of the scanner. Default settings can be
changed with the bar code labels from the Configuration Guide that came
with the scanner.
Appendix A gives the pin definition for the Data ports of the scanner. The pin
definition may be required when you want to make a new cable for
communication with the POS/computer. Technical specifications of this

scanner can be found in Appendix B. Refer to Appendix C for
troubleshooting if the scanner is not working properly.

Product Overview 5
1.3 SCANNING BAR CODES
This scanner is an omni-directional presentation scanner featuring a 7
directional scan field with a 24 lines scan pattern. Bar code labels can easily
be read by presenting them to the scanner.
The scanner's scan volume is illustrated in the figure below. The optimal
reading zone lies between 2 and 30 cm from the scanner window. The scan
depth varies depending on the size of the barcode.
Scanning a bar code label with a presentation scanner is very simple:
present the product’s bar code label to the scanner as illustrated in the
figure below.

Product Overview8
English:
The scanner complies with safety standard IEC 825-1 (1993) for a Class I laser product. It also
complies with U.S. 21CFR1040 as applicable to a Class IIa laser product. Avoid long term
viewing of direct laser light.
Optical:
The use of optical instruments with this product will increase eye hazard. Optical instruments
include binoculars, microscopes and magnifying glasses but do not include eye glasses worn
by the user.
Radiant Energy:
The scanner uses a low-power laser diode operating at 630…670 nm in an opto-mechanical
scanner resulting in less than 0.6 mW peak output power. Laser light observed at 13 cm (5.1
in.) above the window through a 7 mm (0.28 in.) aperture and averaged over 1000 seconds is
less than 3.9 µW per CDRH Class IIa specification. Do not attempt to remove the protective
housing of the scanner, as unscanned laser light with a peak output up to 0.8 mW could be
accessible inside.
Laser Light Viewer:
The scanner window is the only aperture through which laser light may be observed on this
product.
A failure of the scanner motor, while the laser diode continues to emit a laser beam, may cause
emission levels to exceed those for safe operation. The scanner has safeguards to prevent this
occurrence. If, however, a stationary laser beam is emitted, the failing scanner should be
disconnected from its power source immediately.
Adjustments:
Do not attempt any adjustments to or alteration of this product. Do not remove the scanner’s
protective housing. There are no user-serviceable parts inside.
CAUTION: Use of controls or adjustments or performance of
procedures other than those specified herein may result in hazardous
laser light exposure.

1.5 MAINTAINING THE SCANNER
This scanner requires little maintenance. Only occasional cleaning of the
scanner window is necessary to remove dirt and fingerprints. Cleaning can
be performed during operation with a non-abrasive glass spray cleaner and
a soft lint-free cloth.

Product Overview10
1.6 CONTROLLING THE SCANNER FROM THE POS
SYSTEM
This scanner can be controlled from the POS system via the RS232C
interface. Control is achieved by transmitting the following single byte
commands to the scanner. In the default setting the following commands are
available (more details upon request):
ASCII code function byte is also called:
05 Hex power-up re-initialization ENQ or <Ctrl-E>
OE Hex enable (cancels disable) Shift Out or <Ctrl-N>
OF Hex disable Shift In or <Ctrl-O>
12 Hex sleep DC2 or <Ctrl-R>
14 Hex wake (cancels sleep) DC4 or <Ctrl-T>
When the scanner is disabled (indicated by the blinking red LED), the motor
of the scanner will stay on until the scanner goes into sleep mode.

Chapter 2 Installation

Installation12
This scanner can be installed on a counter surface. Instructions for
installation on a counter surface are given in Section 2.3.
Due to many POS systems on the market, a large number of communication
cables are available. Make sure that you have the right cable to connect the
scanner to your POS or computer.
NOTE
The scanner and the host system must be switched off before
starting the installation of the scanner. By following this
precaution you prevent any electrical damage.
You are advised to install the scanner in an air circulated place
out of direct sunlight.
2.1 CONNECTING THE SCANNER
Before you connect any cables to the scanner, check whether you should
guide them through the foot or counter surface!
This scanner features a triple interface in one standard unit:
RS232 + Keyboard Wedge (KBW) + USB and powered USB
(Option).
It also provides:
Auxiliary port for additional scanner
Power connector
If you use “Direct Powering”, power is supplied by the host and you do not
need to connect an external power supply to the Power Input entry.
NOTE
Plug the interface cable prior to connecting power. System will
automatically setup interface.
For changing interface cable, remove power first. Change
interface cable then connect power.
