Enclosure Specifications

The imaging engine was specifically designed for integration into custom housings for OEM applications. The
imaging engine’s performance will be adversely affected or permanently damaged when mounted in an
unsuitable enclosure.

Warning: The limited warranty (on page 31) is void if the following considerations are not adhered to when

integrating the engine into a system.

Electrostatic Discharge (ESD) Cautions

All imaging engines are shipped in ESD protective packaging due to the sensitive nature of the
engine's exposed electrical components.

• ALWAYS use grounding wrist straps and a grounded work area when unpacking
and handling the engine.

• Mount the engine in a housing that is designed for ESD protection and stray electric fields.

ESD has the ability to modify the electrical characteristics of a semiconductor device, possibly
degrading or even destroying the device. ESD also has the potential to upset the normal operation
of an electronic system, causing equipment malfunction or failure.

Airborne Contaminants and Foreign Materials

The imaging engine has very sensitive miniature electrical and optical components that must be protected from
airborne contaminants and foreign materials. In order to prevent permanently damaging the imaging engine
and voiding the limited warranty (on page 31), the imaging engine enclosure must be:

• Sealed to prevent infiltration by airborne contaminants and foreign materials such as,
dust, dirt, smoke, and smog.

• Sealed to protect against water, humidity and be non-condensing.

Refer to page 11 for information on power and thermal considerations.

8

Output Window Properties

An improperly placed window has the serious potential to reduce the imaging engine’s performance.
Careful consideration must be made when designing the output window’s distance and angle relative
to the imaging engine’s camera aperture.

Follow these guidelines when designing the output window.

• The output window material should have a spectral transmission of at least 85% from 580 nm to
680 nm and should block shorter wavelengths.

• It should have a 60-40 surface quality, be optically flat, clear, and free of scratches, pits, or seeds.
If possible, recess the window into the housing for protection or apply a scratch resistance coating
(see Output Window Coatings below).

• Apply an anti-reflective coating to the window surfaces to reduce the possibility of reflective light
interfering with the engine’s performance.

• The clear aperture of the output window should extend beyond the Field of View. Refer to page 10
and pages 20 - 21 for Field of View specifications.

• The window size must accommodate the illumination and targeting areas shown on page 10.

• The window must be parallel to the engine face.

• The distance from the engine face to the inside surface of the window of the enclosure should be

minimized and should not exceed 0.5 mm (0.02") due to possible specular reflections from internal
area illumination.

Output Window Coatings

• Anti-Reflection
An anti-reflective coating can be applied to the inside and/or outside of the window to reduce the
possibility of internal beam reflections interfering with the performance of the engine. If an anti­reflective coating is applied, it is recommended that it be on both sides of the window providing a

0.5% maximum reflectivity on each side from 600 - 700 namometers at the nominal window tilt angle.
The coating must also meet the hardness adherence requirements of MIL-M-13508.

• Polysiloxane Coating
Applying a polysiloxane coating to the window surface can help protect the window from surface
scratches and abrasions that may interfere with the performance of the engine. Recessing the window
into the housing can also provide added protection against surface damage such as scratches and
chips. If an anti-reflective coating is used, there is no need to apply a polysiloxane coating.

9

Optical Clearance Specifications

The window size and enclosure design must provide unobstructed clearance for the illumination and targeting
areas shown below to avoid optical interference that decreases the engine's performance.

System Considerations

In order to ensure proper operation of the decode engine’s electrical system; care must be taken to ensure the
following requirements are met.

Power Supply Decoupling*

The engine requires clean filtered power supplies for both the VLED and Vimager power rails. Special care
must be taken for the Vimager line as this voltage is used to power the imaging sensor. The power line must
be heavily decoupled to prevent noise from coupling into the engine, which can reduce image quality.

Power Sequencing*

All signals to and from the engine (except for VLED) are relative to Vimager. These pins are not over voltage
tolerant. As such, care must be taken to ensure that the voltage on these signals never exceed the voltage on
the Vimager pin.

Refer to page 11 for additional electrical specifications and page 25 for pinout information.

High-Speed Digital Bus*

Due to the relative high-speed nature of the Camera Data bus (48 MHz max), care must be taken to ensure
signal integrity and minimize clock skew. To reduce electromagnetic interference and ringing on the lines,
22-ohm series resistors have been added to each of the pixel data lines as well as the pixel clock and HSYN
signals. The capacitive loading and trace length on these lines should be minimal to ensure proper operation.

Thermal Considerations

The engine is qualified at temperatures from 0°C to 40°C (32°F to 104°F). Care must be taken to ensure that
ambient temperatures do not exceed this range in order to guarantee operation. The illumination LEDs
produce a considerable amount of heat when left on for extended time periods. The on time of these LEDs
should be minimized and airflow should be provided whenever possible to minimize internal heating.
Excessive heating can damage the LEDs and degrade image quality.

* See page 25 for additional information on electrical specifications.
See pages 25 and 26 for additional information on the engine and flex cable pinouts.

Theory of Operation

Overview

The IS4910 imaging engine series is specifically designed for integration into handheld portable data terminals
or other OEM devices used for barcode scanning and/or OCR applications. Since the imaging engine
functions like a digital camera, the engine is capable of digital image capture, document lift, and signature
capture. With software integration, the non-decode engine will support decoding of all standard 1D & 2D
barcodes, reading OCR.

The compact engine has a 1.2M pixel CMOS imaging sensor, high intensity illumination LEDs, and an LED
targeting system. The non-decode engine also incorporates FirstFlash

®

a patented technology that regulates

the illumination time during image capture, reducing the need for multiple image acquisition.

The IS4910 series has two types of imaging modes, the Snapshot mode and the Video mode. The Snapshot
mode facilitates fast and accurate image acquisition with a minimum amount of power consumption. In this
mode, the LEDs are only activated for a very short time while FirstFlash ensures proper illumination.
The amount of images required is minimized, ultimately reducing the engine's power consumption. Detailed
information on the Snapshot mode can be found on page 14. The second type, the Video mode, enables fine
control of the camera exposure time making the mode suitable for high ambient light applications. Detailed
information on the Video mode can be found on page 16.

2

Communication with the image sensor is done over two buses, the control bus (I

C) and the data bus. The
Control bus is used to send programming commands to the image sensor. The data bus is used to transfer
images from the image sensor to the host system. The image data rate is determined by the Pixel Clock
(PCLK), which has a maximum frequency of 48 MHz. Note that on some host systems, such as those based
on the XScale PXA270 processor, the platform may not be able to support the 48 MHz pixel clock. In these
applications, the pixel clock can be configured to 24 MHz or 12 MHz via the (I

2

C) control bus. See Figure 9 on

page 13 for an illustrated depiction of the engine’s system architecture.

12

Figure 9. IS4910 / IS4911 System Architecture

Honeywell Scanning and Mobility provides a Software Development Kit (P/N 46-00550) that will ease the
functional integration of the IS4910 or IS4911 non-decode engine. The SDK includes all the necessary
software components needed to enable an application developer to control and communicate with the engine,
acquire images, and decode barcodes. Additional information about the Software Development Kit and its
application programming interfaces (APIs) is provided in the IS4910 Series Area Imaging Engine
Programmer's Manual (P/N 00-02291). Contact a, customer service representative at 1-800-436-3876 for
additional information on this item and the Software Development Kit.

13

Snapshot Mode

In the Snapshot mode of operation, image acquisition begins on the rising edge of the Trigger signal.
Image integration continues until the trigger line is brought low at which time the Image Data is output on the
Camera bus. In this mode, the area illumination is coincident with the integration time and is activated on the
rising edge of the Trigger signal. The illumination will remain on until the FirstFlash circuitry determines that
sufficient light has reached the sensor. At that point, the FirstFlash circuitry will then automatically disable
illumination. The user can override the FirstFlash circuitry by activating the Illum_On signal along with the
Trigger signal. For additional information, refer to Snapshot Illumination Waveforms on page 15.

The minimum Trigger pulse time required to initiate image acquisition in Snapshot mode can be calculated
using the following formula:

Ttrig_min = 84 + (<image-height> + 19) * 9 / PCLK

Where PCLK is the pixel clock output of the image sensor
and can be programmed to 48 MHz, 24 MHz, or 12 MHz.

For example, in systems that cannot support 48 MHz pixel clock rates (such as Xscale PXA270 processor
based platforms) the pixel clock can be reduced to 24 MHz or 12 MHz. Thus, for the default image height of
960 rows at 24 MHz pixel clock, the Trigger pulse time should be at least 451 µs.

As mentioned above, the trigger pulse controls both the image integration time and the maximum duration of
the illumination. The maximum time is application specific. Increasing the time will typically result in brighter
images but longer exposure time will make the unit susceptible to motion blur.

Software used by the engine device driver and CamLib APIs included in the Software Development Kit provide
the ability for precise control of the timings of the Trigger signal, the image sensor, and the image dataflow
from the camera to the host system.

The actual time of the illumination flash in Snapshot mode can vary between the minimum illumination time
and the maximum illumination time. The maximum illumination time is determined by the duration of the
Trigger signal. The minimum illumination time is determined by the duration of the Illum_On signal. The actual
time of the illumination flash is determined by the internal Microcontroller based on the measurement of the
light intensity performed by the FirstFlash circuitry.

When the light intensity, as measured by the FirstFlash circuitry, exceeds a pre-set factory threshold, the
Microcontroller immediately turns illumination off if the time elapsed from the start of illumination is greater than
the minimum illumination time (i.e. if the Illum_On signal is de-asserted); otherwise, it waits until the minimum
illumination time elapses and then turns the illumination off.

Precise control of the timings of the Illum_On signal is done in software by the engine device driver and
CamLib APIs included in the Software Development Kit.

14

Snapshot Illumination Waveforms

The following waveforms show how the illumination LEDs are controlled relative to the input signals
(Trigger and Illum_On) during the snapshot mode. The Trigger signal determines when the illumination and
image integrations begin. In addition, the duration of this signal determines the maximum integration and
illumination time. The Illum_On signal can be used in conjunction with the Trigger signal to ensure a minimum
amount of illumination.

Example 1: Snapshot mode with Illumination duration controlled by FirstFlash circuitry only (see figure below).

= Denotes the actual duration of LED light will be determined by the FirstFlash circuitry. The

duration will vary based on object, object distance, and ambient light conditions.

Figure 10. Example 1

Example 2: Snapshot mode with Illumination being forced on for a given duration after which FirstFlash

circuitry takes over (see figure below).

= Denotes the actual duration of LED light will be determined by the FirstFlash circuitry. The

duration will vary based on object, object distance, and ambient light conditions.

Figure 11. Example 2

15

Video Mode

The Video Mode allows for streaming video from the CMOS imager. The main advantage in the mode is that
the user has fine control over the exposure time. Fine control over the exposure time makes this mode well
suitable for high ambient light applications. The Video Mode is initiated through commands via the I

2

C bus.
During this mode of operation, the Trigger signal must be held low. If lighting is required, the Illumination LEDs
can be controlled via the Illum_On control signal.

Control of all signals and image dataflow in Video Mode is done in software by the engine device driver and
CamLib APIs included in the Software Development Kit. See SDK documentation for more details.

When not in Video Mode, the image sensor is always ready for Snapshot image acquisition.

Targeting

The engine uses a targeting LED to indicate the center of the imaging field. This LED can be activated at any
time by asserting the Aimer signal. The targeting LED is independent of the mode of operation and
illumination. However, it is strongly recommended that the targeting LED not be activated during image

acquisition as the light from the targeting LED will be visible in the image and may result in “hot
spots”. Control of the aiming mechanism is done in software by the IS4910 device driver and CamLib APIs

included in the SDK.

I2C Interface

The IS4910 series engines use an I2C compliant interface to communicate with the host system. The bus
allows the host to communicate directly with the image sensor and illumination microcontroller. Both of these
devices function as auxiliary* devices on the bus. The illumination Microcontroller is capable of running at
speeds up to 100 kHz whereas the image sensor can support frequencies up to 400 kHz. The standard
configuration of the IS4900 series of imaging engines does not incorporate pull up resistors on the SDA and
SCL lines in order to allow flexibility for the end user when choosing the resistor values. These resistors must
be provided by the host system and sized to meet the I
specification must be observed in order to guarantee proper operation of the engine.

The two I

C devices used in the IS4910 Engine use the following addresses:

• CMOS Image: 0x10

• Illumination Micro: 0x61 and 0x70

Camera Bus Timings

The non-decode engine outputs pixel data via an 8-bit parallel data bus. The rate at which data is output is
determined by the pixel clock, which can be set for 48, 24, or 12 MHz. When the horizontal and vertical synch
signals are high, valid pixel data is latched on the rising edge of the PCLK. New pixel data is then driven on to
the bus on the falling edge. The VSYNC, HSYNC, and Pixel Data timings are relative to the PCLK and are
related as shown in the following timing diagram.

Wake Up Timing

When exiting sleep mode the engine will require a minimum wake up time before an image can be acquired.
Wake up is initiated by pulsing the Illum_On pin for a minimum of 250 µS. The pulsing wakes up the on board
microcontroller and oscillator. After this pulse is brought low, an additional 10 mS delay is required to ensure
that the oscillator has stabilized. After the additional 10 mS delay, the oscillator is stabilized and the imager is
ready to receive its configuration via the I

During sleep, the imager looses all configuration settings therefore all applicable settings will need to be
updated. The total time for the device to wake up will be dependant on how many registers need to be
reconfigured, the running speed of the I
(i.e. repeated stop vs. no repeat stop transmission).

Wake up time calculation:

Regulatory Compliance

Safety

The IS4910 series area imaging engines are designed to meet the requirements of IEC Class 1 in accordance
with IEC 60825-1:1993+A1+A2. IEC Class 1 is defined as follows:

The specifications required for agency approval are not obtainable until the IS4910 / IS4911 area imaging
engine is used in its final configuration. Honeywell International Inc. is unable to fulfill these requirements
because the imaging engine will operate differently depending upon where the engine is used as a component.

If the product containing the IS4910 series engine is to be used in another country, the manufacturer who

incorporates the imaging engine into their product is responsible for fulfilling any regulatory
compliance requirements for that country. Refer to one of the following sections for further explanation.

Europe

The CE Mark is required on products that incorporate the IS4910 series engine if the products are to be
imported into European Economic Area (EEA) countries. Use of the CE Mark requires compliance with
directives and standards dependent upon the type of product. Information may be found at

http://europa.eu.int/comm/enterprise/newapproach/

“Safety of LED products”

Compliance with either of the standards listed above is required for the product to bear the CE mark.

Note: Non EEA countries may impose additional testing/certification requirements.

EMC

All combinations of IS4910 area imaging engines and associated electronics will require certification of
compliance with the European EMC Directive. EMC compliance of finished products in Europe can be
accomplished by the following method:

The manufacturer may certify to the EC’s Electromagnetic Compatibility Directive 89/336/EEC.
Compliance is required for the product to bear the CE Mark.

Note: Non EEA countries may impose additional testing/certification requirements.

The IS4910 series area imaging engine is designed to meet EN55022 Radiated Class B emission limits.
The engine was installed in a representative system and tested for compliance.
