Gryphon™ GFE4400
Integration Guide
This document gives instruction, mechanical details, and design consid-
erations to integrate the Gryphon™ GFE4400 model (designated as
“scan engine” or “OEM scan engine” in this manual) specifically into
equipment-integrated scanning applications.
Overview
The GFE4400 OEM scan engine is a compact decoding omni-direction-
al imaging scan engine for fixed position OEM integration, such as price
verifiers, kiosks, vending machines, point-of-sale (POS) terminals, and
other equipment-integrated scanning applications. The new proprietary
imaging technology excels at capturing hard-to-read bar codes in om-
ni-direction orientation.
A typical system using the scan engine consists of a host system such as a
price verifier or kiosk. The host system interfaces with the scan engine
and receives decoded bar code data produced by the scan engine. The il-
lumination LEDs in the scan engine emit visible light when a bar code
passes through the scan volume area and light is reflected off the bar code.
The scan engine captures an image, processes it into a digital signal and
decodes it into data that can be used by the host system. The scan engine
has different operational modes which can be selected via special pro-
gramming bar codes.
The OEM scan engine is the same reader as that found in the Gryphon

Overview

GFS4400 scan module. This document is meant to give instruction, me-
chanical details, and design considerations to integrate the OEM scan en-
gine model only.
Details on the Configuration Settings and Programming are found in the
GFS4400 Product Reference Guide (PRG). The Datalogic Aladdin Con-
figuration Utility (available free from the Datalogic website) can also be
used to modify settings.
Demo Kit
To facilitate the scan engine OEM integration process, Datalogic offers a
demo kit that contains:
• GFE4490 Scan Engine
• RS-232 cable
• USB cable
• Keypad containing trigger button & LED indicators
•IntegrationGuide
The kit can be ordered as GFE4490-DEMO. Contact your Datalogic
representative or salesperson for more information.
Unpacking the Scan Engine
The scan engine is shipped in custom packaging. Carefully open the pack-
age, and inspect for the following:
• scan engine
• power supply (if ordered)
• interface cable (if ordered)
If any parts are damaged or you need additional hardware, please contact
Technical Support.

Scan Engine Care
The scan engine contains sensitive components which require special
handling. Datalogic may not warrant damage due to improper handling.
• Do not disassemble the scan engine. Doing so will void the war-
ranty.
• Use standard ESD precautions & policies when handling the
GFE 4400 scan engine.
• Avoid touching the camera lens. Fingerprints will degrade the
scan engine's performance.

Mounting the Scanner
This section describes how to design the mounting for optimum scanner
performance.
General Considerations
A typical system uses the scanner mounted inside a host enclosure, with
an opening for the scanning pattern to exit and read bar codes. The open-
ing should be the size of the scanner field of view at a minimum, but only
exposing as much of the scanner as necessary.
Although the scanner has been designed to be rugged, it is important to
consider the effect of the environment on the scanner. In particular,
mounting should minimize the possibility of foreign objects coming into
contact with the electronics. Such contact could damage the device or re-
duce the scanner's performance.
Mounting
The primary method of mounting to the host enclosure is to attach the
scanner using the three mounting holes provided in the main PCBA. "Me-
chanical Specifications"
on page 26 has mechanical drawings of the scan-
ner, including the position of the mounting features.
The scanner can be mounted upside down with no loss in scanning per-
formance.
Mounting the Scanner Standalone
The OEM scanner is not intended for use in a standalone application.
This model is intended to be integrated inside a host enclosure. GFS4400
models should be used when a standalone application is required.

Scan Engine Electrical Connections
The GFE4400 scan engine has three application ports for device integra-
tion, as indicated below, a Host (J1), User (J2), and Good Read Beep In-
terface.

Host Interface
The Host Interface connection (J1) provides all the connection points for
either RS-232 or USB host communications. Additionally, this connec-
tor is input for power and provides access to the external triggering input
and digital signal output functions. The assignment of the connector
pins are indicated in
Table 1 on page 6.

User Interface
The User Interface connection (J2) provides the integrator a means to
monitor scan engine status (LEDs), and offers an additional mechanism
for manually triggering the device.
The user connection (J2) uses a Molex part number, 0527460671,
0.50mm (.020") Pitch FFC/FPC Connector, Right Angle, SMT, ZIF,
Bottom Contact Style, 6 Circuits, Gold Contact Plating. For custom ad-
aptations, the integrator must interface using an FFC (Flat Flexible Cable)
that mates properly to scan engine ZIF connector.

Good Read Beep Interface
The Beep Interface connection (J3) provides the integrator a means to
tap the engine's good read beep signaling and interface with an external
audio device.
The Beep Connection (J3) is a Molex part number, 53261-0271,
1.25mm Pitch PicoBlade™ 2 Circuit Header. To attach to this SMT
Right Angle Header, the integrator should use the Molex mating plug,
51021-0200 and wire crimp terminal, 50079-8000 or equivalent.
Table 3. J3 Connector Pin Assignment
The Good Read Beep is a 2750Hz signal burst for 100ms provided by an
on board Open Collector transistor drive circuit. Below is a simple exam-
ple of an external audio implementation which calls out a readily avail-
able Magnetic Audio Buzzer. Any other type of audio-producing element
may require a custom interface and drive circuitry. See
"Technical Speci-
fications" on page 19 for additional information about Good Read Beep
output.

Scanner Ventilation
When mounting the scanner inside an enclosure, it is important to have
proper ventilation to ensure that the scanner temperature does not exceed
the maximum range as listed in
"Technical Specifications" on page 19. The
reliability of the scanner may be compromised if the temperature range is
not maintained.

Mounting the Scanner
Integration Guide 15
Integrating the Scanner to Read at the Proper Dis-
tance
When deciding how to mount the OEM scanner, there are many criteria
that must be considered. First, there are minimum and maximum dis-
tances that the bar code can be from the front of the scanner to be prop-
erly read, depending on the size of the bar code. These distances, or depth
of field, are specified in
"Technical Specifications" on page 17.
The scanner must be positioned so that the scan volume and illumina-
tion light will cover the entire bar code. The scan volume is shown in
Figure 9 . The combination of the Scan Volume and the illumination
light is called the Field of View. Designing around the scanner Field of
View is explained more in the following section.
Figure 9. Scanning Volume

Design of the Scanner Opening
The design and placement of the scanner opening within a host enclosure
are critical for optimum system performance. A typical system uses the
scanner mounted inside a host enclosure, with an opening to allow the
scanner Field of View to exit the scanner window and read bar codes.
Use the following guidelines to design the host enclosure and scanner
opening, along with the dimensions shown in
"Mechanical Specifications"
on page 26.
• The opening must not block any of the outgoing illumination
light, described by dimensions of the scanner Field of View.
• Ensure that there are no reflective surfaces around the area of the
scanner opening.
• The minimum opening size must increase as the distance between
the scanner and the host enclosure window increases. This is nec-
essary to accommodate the width and height of the scan volume.
• The opening or other parts of the host enclosure must not enter
the Field of View in order to allow the bar code image to be cap-
tured by the scanner.
• If the scanner is flush against the opening, the opening must be
the size of the scanner at a minimum, but only exposing as much
of the front surface of the scanner as necessary.
