Preface

The Datalogic DLL2020-WO is a high performance omni-directional scanner, which
provides optimal scanning conditions. The DLL2020-WO shares the same quality of
the GOLDRUSH

TM

polygon and Scantium decoder chip as Datalogic’s popular Hunter
H-3010, Pollux P-4010 and Castor C-5010 scanners. Together with its compact and
ergonomic design, operator fatique and other discomforts are less then any
competitive omni-directional scanner.

These characteristics make the DLL2020-WO especially suitable for installation in
small counters such as in drugstores, pharmacies, department stores, tobacconists,
kiosks, petrol stations, and convenience stores.

The omni-directional scan field of the DLL2020-WO generates a scan pattern of
16 lines, ensuring high performance scanning. Featuring an unequalled scan rate of
800 scans per second, the DLL2020-WO is an aggressive scanner.

Barcodes are read simply on presentation to the scanner window. However, the
ergonomic design of DLL2020-WO rubber sleeve, which fits naturally in the hand,
makes the unit easy to pick up when larger or heavier products have to be scanned.

The scanner con be installed ‘free-standing’ on a counter surface using its protective
rubber sleeve or without the sleeve, flush or surface fixed to check-out furniture,
making for a very neat installation.

The DLL2020-WO can also be supplied in different colours to match with corporate/­retail designs and schemes thus enhancing the check-out environment even further.

This manual contains two chapters and three appendices. The first chapter describes
the DLL2020-WO scanner, its general features as well as the way in which it can be
used. The precise instructions for installing the scanner are listed in the second
chapter. Default settings can be changed using the bar code labels in the
Configuration Guide supplied with the scanner. Appendix A shows the connector types
of the scanner. Technical specifications of the DLL2020-WO can be found in Appendix
B. Refer to Appendix C for troubleshooting if the scanner is not working properly.

The various parts of the DLL2020-WO are:

Sleep mode switch If a sleep mode time-out has been programmed,

the scanner can be reactivated by pressing this
switch. The sleep-mode feature can be program­med by means of the menu labels in the
Configuration Guide.

NOTE: The default value for the sleep mode

time-out is set to 30 minutes. When the
scanner is in sleep mode, the LED is
intermittently flashing red.

Red LED The red LED indicates that the scanner is ready to

read a bar code.

Green LED The green LED indicates a good read.

Good read buzzer The buzzer sounds whenever data have been

correctly read. The frequency can be adjusted by
means of the menu labels from the Configuration
Guide.

Rubber sleeve A rubber sleeve encloses the scanner. The sleeve

protects the scanner, and takes care that it does
not slide when installed ‘free-standing’ on a counter
surface. Furthermore, its ergonomic design makes
the unit easy to pick up; it fits naturally in the hand.

Detachable handle A handle can be attached to the scanner,

depending on the preference of the user. The
handle makes the scanner easy to pick up, in case
large or heavy products need to be scanned.

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 DLL2020-WO uses a low-power laser diode

operating at 650 nm in an opto-mechanical scanner
resulting in less than 0.7 mW peak output power.
Laser light observed at 15.0 cm (5.9 inch) 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 0.90
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 to make any adjustments to or

alteration of this product. Do not remove the
scanner’s protective housing. There are no user­serviceable parts inside.

CAUTION Use of controls or adjustments or performan-

ce of procedures other than those specified
herein may result in hazardous laser light
exposure.

1.4 Maintaining the scanner

The DLL2020-WO scanner requires little maintenance. Only occasional
cleaning of the scanner window is necessary in order to remove dirt and
fingerprints. The scanner can be cleaned during operation. To this end use
a non-abrasive glass spray cleaner and a soft lint-free cloth only.

1.5 Controlling the scanner from the pos system

The DLL2020-WO can be controlled from the POS system via the RS232C
interface. Controlling is accomplished by transmitting the following single­byte commands to the scanner. In the Datalogic default setting the
