INTRODUCTION
The Datalogic DLL2020 is a high perform ance omni-directional scanner,
which provides optimal sc anni ng conditions.
Together with its compact and ergonomic design, operator fatigue and
other discomforts are less than any competi tive 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 sc an field of the DLL2020 generat es 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 ‘f ree-standing’ on a counter surface using
its protective rubber sleeve or without the s leeve, fl ush or s urfac e fixed to
check-out furniture, making for a very neat instal l ation.
This manual contains three chapters and three appendices. The first
chapter describes the DLL2020 sc anner, its general features as well as
the way in which it can be used. The precise ins truc t ions f or ins tall ing 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 s canner is not working properly.

1.1 UNPACKING THE DLL2020
Take the scanner and its accessories out of the box and remove all
packing material s. Refer to the packing lis t 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 s leep mode time-out has been programmed,
the scanner can be reactivated by pres sing this switch. The sleep-mode
feature can be programmed us ing the Software Configurat ion Guide part
number 90ACC1620.
The default value for the sleep mode time-out is set to
30 minutes. When the sc anner is in sleep mode, the
LED is intermittently flashing red.
NOTE
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 s canner, and t akes care that i t does not s lide when instal led
‘free-standing’ on a counter surf ace. Furthermore, its ergonomic design
makes the unit eas y t o pi ck up; it fits nat ural l y i n the hand.

GETTING STARTED
Radiant Energy The DLL2020 uses a low-power laser diode operating
at 650 nm in an opto-mechani cal scanner resulting i n 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 s econds is less than 3.9
µW per CDRH Class IIa specification. Do not attempt to remove the
protective housing of the scanner, as unsc anned laser light with a peak
output up to 0.90 mW could be accessibl e i nside.
Laser Light Viewer The sc anner window is the only aperture through
which laser light may be observed on t his product.
A failure of the scanner m otor, while the laser diode conti nues 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 i ts power source immediat el y.
Adjustments Do not att empt t o mak e any adjustm ents to or alterat ion of
this product. Do not remove the s canner’s protect ive housing. There are
no user-serviceable parts ins i de.
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous laser light exposure.
CAUTION

1.5 MAINTAINING THE SCANNER
The DLL2020 scanner requires little maintenance. Only occasional
cleaning of the scanner window is necess ary in order to remove dirt and
fingerprints. The scanner c an be cleaned during operation. To this end
use a non-abrasive glass spray cl eaner and a soft lint-free cloth onl y.

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 si nglebyte commands to the scanner. In the Datalogic default setting the
following commands are avai l abl e (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 dec oding is disabled, the scanner motor will remain
switched-on until the scanner goes i nto 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.
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.
NOTE
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.
You are advised to install the scanner in an air
circulated place out of di rect sunlight.

The Freeze Frame m ode is a special trigger mode allowing to aim t he
laser pattern on the code before reading.
To work in this mode:

CONFIGURATION
Single Line Mode (DLL2021 only)
The single line option allows tem porarily switching from full scan pattern
to a single scan line preventing the wrong barcode to be read. This
feature is especially helpful on sheets or products where multiple
barcodes are printed.
To use this option proceed as f ol l ows:
1. Press the button on top of the scanner t o switch from the full scan
pattern to a single scan li ne;
2. Aim t he singl e sc an line on t he barcode t o be scanned while holding
the button;
3. Make the line to completely cross the barcode, then release the
button. A beep indicates the barcode has been accepted by the
scanner;
4. After successful reading the s ingle line blinks. During the scan line
blinking, the scanner will not read a barcode. Af ter one second, the
scanner will return to normal m ode. I f pres sing t he trigger during t he
scan line blinking, the single line procedure will start again.
