INTRODUCTION
The Datalogic DLL2020 is a high performance omni-directional scanner,
which provides optimal scanning conditions.
Together with its compact and ergonomic design, operator fatigue and
other discomforts are less than any competitive omni-directional scanner.
These characteristics make the DLL2020 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 generates a scan pattern
of 16 lines, ensuring high performance scanning. Featuring an
unequalled scan rate of 800 scans per second, the DLL2020 is an
aggressive scanner.
Barcodes are read simply on presentation to the scanner window.
However, the ergonomic design of DLL2020 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.
This manual contains three chapters and three appendices. The first
chapter describes the DLL2020 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 chapter 3 "Configuration".
Appendix A shows the connector types of the scanner. Technical
specifications of the DLL2020 can be found in Appendix B. Refer to
Appendix C for troubleshooting if the scanner is not working properly.

1.1 UNPACKING THE DLL2020
Take the scanner and its accessories out of the box and remove all
packing materials. Refer to the packing list in order to ensure that you
have received all the items ordered. Visually inspect the scanner and
accessories for any visible traces of damage. Refer to the figure in
paragraph 1.4 to locate the interface label and verify if the scanner
interface corresponds with the host system interface. Immediately
contact your supplier if anything appears to be damaged, or if the
supported interface does not correspond with the host system interface.

The various parts of the DLL2020 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 using the Software Configuration Guide part
number 90ACC1620.
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 beeper: The beeper sounds whenever data have been
correctly read. The frequency can be adjusted using the Software
Configuration Guide part number 90ACC1620.
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.
1.2 AVAILABLE MODELS
The following two models are available:
− DLL2020, standard model
− DLL2021, with single line option (see par. 3.7 for details).

1.3 SCANNING BAR CODES WITH THE DLL2020
15cm
The DLL2020 is an omnidirectional scanner featuring a 4-directional scan
field with a 16-line scan pattern. Bar codes can easily be read by
presenting them to the scanner. The scan volume is illustrated in the
figure above. The optimal reading zone lies between 3 and 15 cm from
the scanner window. However, bar codes can still be read up to 25 cm
(10 inches) from the scanner window.

Radiant Energy The DLL2020 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 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
The DLL2020 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.

1.6 CONTROLLING THE SCANNER FROM THE POS
SYSTEM
The DLL2020 can be controlled from the POS system via the RS232
interface. Controlling is accomplished by transmitting the following single-
byte commands to the scanner. In the Datalogic default setting the
following commands are available (more details upon request):
Command Description Hex.
Ctrl - E Power-up re-initialization 05 Hex
Ctrl - N Enable decoding 0E Hex
Ctrl - O Disable decoding 0F Hex
Ctrl - R Sleep 12 Hex
Ctrl - T Wake 14 Hex
When the scanner decoding is disabled, the scanner motor will remain
switched-on until the scanner goes into sleep mode.

2 INSTALLING THE DLL2020
2.1 CONNECTING THE SCANNER
This chapter describes the instructions necessary for installing the
DLL2020 scanner.
Due to many POS systems on the market, a large number of
communication cables is 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.
Follow these steps carefully in order to install the scanner:
1. Locate the optimal scanner position in relation to the counter
surface.
Pay attention to the product flow, the distance to the counter edge
and convenience for the operator.
2. You have two options to connect the scanner to your POS or
computer.

NOTE
The present manual provides information on how to set the
DLL2020 reader in operation, as well as to set up its basic
configuration parameters.
Additional customized configurations are also available
by changing basic parameters: please refer to the
Software Configuration Manual (Part No. 90ACC1620)
for a complete list of codes and procedures.
3.1 CHANGE SCANNER SETTINGS
In order to change the scanner settings please follow the sequence
below:
1. Enter the scanner Programming Mode by scanning the Enter/Exit
code (see par. 3.4);
2. Change Scanner Settings by scanning the desired codes from
par. 3.5 to par. 3.9.
3. Exit the scanner Programming Mode by scanning the Enter/Exit
code in par. 3.4.
Reading the Enter/Exit code in par. 3.4 gives a double tone beep (Low
High).
Example:
For changing the keyboard to German the following codes must be
scanned successively:
"Enter/Exit and Save Programming Code", "German", "Enter/Exit and
Save Programming Code".
After reading a valid configuration barcode in Programming Mode the
scanner will give a High beep.
The scanner will generate a Low beep after receiving an unexpected
code.
At any moment (in Programming Mode) you can scan the "Return to
Factory Default Settings" code to return to default settings.
