only, solely for integration and authorizes the Integrator to transfer the license to use the Software solely to
the end user of the integrated product. This Agreement does not convey ownership of the Software to Inte-
grator. Title to the Software shall be and remain with Datalogic or the third party from whom Datalogic has
obtained a licensed right. As used in this Agreement, the term "purchase" or its equivalents when applied to
the Software shall mean "acquire under license." Integrator is not entitled to receipt or use of the source code
to any Software.
2.2 Integrator shall not modify, decompile, disassemble, reverse engineer, or otherwise reproduce or remanu-
facture the Software, whether modified or unmodified, nor sell, assign, sublicense, distribute, lend, rent,
give, or other- wise transfer the Software separately from the Datalogic Product to any other person or orga-
nization, for purposes other than as expressly provided in this Agreement.
3. Transfers, Support.
3.1 Any copying, installing, reproduction, remanufacture, reverse engineering, electronic transfer, or other use
of the Software on other than the designated Datalogic Product will be a material breach of this Agreement.
However, in the event that Datalogic discovers such breach, Datalogic may elect not to terminate this Agree-
ment or the granted licenses, but instead may elect to notify Integrator that Integrator is deemed to have
ordered and accepted a license for each breaching use. Integrator shall pay Datalogic the applicable list price
for such licenses as of the date of such breach.
3.2 Integrator is authorized to integrate the Datalogic Product into specific products as authorized by Datalogic.

erty of Datalogic and Datalogic's third party licensors and Integrator acquires no right or interest in any Pro-
prietary Information.
5.2 Integrator shall not disclose, provide, or otherwise make available the Proprietary Information of Datalogic or
its third party licensors to any person other than Integrator's authorized employees or agents who are under
confidentiality agreement, and Integrator shall not use the Proprietary Information other than in conjunction
with use of the Datalogic Product exclusively for Integrator's internal business purposes. Integrator shall take
steps to protect the Proprietary Information no less securely than if it were Integrator's own intellectual prop-
erty.
5.3 The provisions of this Proprietary Information Section shall survive and continue for the life of the Datalogic
Product or five (5) years after the termination of this Agreement, whichever is longer.

WARNING
STANDARD LASER SAFETY REGULATIONS
This product conforms to the applicable requirements of both CDRH 21 CFR 1040
and EN 60825-1 at the date of manufacture. For installation, use and maintenance,
it is not necessary to open the device.
Use of controls or adjustments or performance of procedures other than those
specified herein may result in exposure to hazardous visible laser light.
The product 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. Avoid that the laser
beam hits the eye of an observer, even through reflective surfaces such as mirrors,
etc.
ATTENTION
NORMES DE SECURITE LASER

Exit Window Recommendations
The use of a double-sided AR coated exit window is strongly rec-
ommended.
Avoiding scratched windows
Scratches on the exit window can strongly affect the reading performance. It
is recommended to use an exit window having a scratch-resistant coating
and to position the engine window in a recessed position.
Window material
The exit window is an integral part of the imaging system and should be
designed and selected to preserve the optical quality of the system. It is rec-
ommended to use only cell-cast plastics or optical glass.
Common materials and their characteristics are shown in Table 1below.

Overview
Integration Guide 11
Description:
• POWER_ON signal can be used by host to switch-on/off the whole Scan
Engine: leave it unconnected if not used
•HW_TRIGGERsignalcanbeused to physically
• issue a “trigger pressure” event to the Scan Engine: leave it uncon-
nected if not used
• VBUS, D+, D- and GND are the standard USB interface lines
HW_TRIGGER Signal
This paragraph describes different ways to drive the HW_TRIGGER signal in
order to instruct the Decoder to start acquisition & decode process. Each of
these Scan Modes must be first issued (programmed) to the Decoder before
to use it. The current default configuration is “Trigger Single”.
In the following pictures, “PRESS” and “RELEASE” words refer to the common
meaning of pressing a push button and releasing it in order to obtain a spe-
cific behavior. The current release of the Decoder board has the HW_TRIG-
GER signal with the following level meaning:
Software TRIGGER Commands
The “PRESS” and “RELEASE” events can be issued also by way of the USB com-
munication port (COM emulation only) and the corresponding commands are
listed here below:
Command ASCII Code Meaning
X88 (58h) PRESS
T84 (54h) RELEASE
The behavioral description of the Scan Engine is the same as that shown
above for HW_TRIGGER Signal.
Level Meaning
n/c or ‘0’ = GND PRESS
‘1’ = VBUS RELEASE
