Introduction
Product Overview
The IS4920 is a miniature area-imaging engine and decode board with image capturing and bar code decoding capabilities. The engine module consists of a non-decode imaging engine (IS4910), a decode board and two flex cables. The IS4920 features a mega-pixel CMOS sensor, integrated illumination, and patented
FirstFlash® technology; together they ensure capturing a high-resolution image with optimal brightness each time. IS4920 also has a wide-angle lens design, which covers a large scan area and delivers a true omnidirectional scanning performance. The high-quality images produced by the imaging engine can be used for decoding bar codes, image upload, signature capture, document lifting and reading OCR fonts.
The decode board is powered by a fast processor and SwiftDecoder™ software to decode a wide array of 1D and 2D bar codes plus OCR fonts. The decode board supports TTL level RS232 or USB 1.1 communication.
The decode board is compatible with MetroSet2, a PC-based software for easy configuration.
IS4920 is designed with the industrial standard size, mounting options and output to facilitate integration into existing applications. The imaging engine’s miniature size makes IS4920 ideal for integration into data terminals and other small devices. IS4920 is supplied as an assembled module with a mounting bracket or as separate components for custom mounting. The imaging engine’s unique open system architecture allows
IS4920 to accept third party and custom plug-ins, giving the IS4920 virtually unlimited application flexibility.
The small yet powerful engine delivers a scanning performance that rivals a full-fledged handheld scanner.
A high-density version, IS4921, is also available.

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 49) is void if the following considerations are not adhered to when integrating the area-imaging engine into a system.
Electrostatic Discharge (ESD) Cautions
All engines and decode boards are shipped in ESD protective packaging due to the sensitive nature of the 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 49), 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 condensation.
Refer to page 15 for information on power and thermal considerations.
12
Output Window Properties
An improperly placed window has a 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.
• The output window 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 14 and pages 29 - 30 for Field of View specifications.
• The window size must accommodate the illumination and targeting areas shown on page 14.
• 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, the coating is recommended to be on both sides of the window providing a
0.5% maximum reflectivity on each side from 600 - 700 nanometers 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.
13
Optical Clearance Specifications
The window size and enclosure design must provide unobstructed clearance for the illumination and targeting
areas shown below in figures 14 and 15 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*
The decode engine is powered from the host device via the VIN and GND pins of the ZIF connector on the decode board. This voltage must be maintained within the specified voltage range at the decode board
(see electrical specifications on page 34). Voltage drops in the host flex cable must be taken into account.
The power must be clean and heavily decoupled in order to provide a stable power source.
Note: The power supply must be able to handle dynamic current loads because the input current will increase considerably when the illumination LEDs are enabled.
Host Flex Cable
The host flex cable is used to carry power and data signals between the decode engine and the host system.
The flex cable should allow for minimal voltage drop and maintain a good ground connection between the host and the decode engine. In terms of grounding and voltage drop, a shorter cable is better.
In addition to power, the flex cable will also carry the digital signals required for communication. The cable design is especially important in the case of USB due to the relative high speed of the USB signals.
The impedance of the cable should match, or be as close as possible to, the impedance of the USB driver
(approximately 45 ohms per trace).
The routing of the host flex cable also plays a critical role in the system design. The cable should be routed away from high frequency devices since these frequencies can couple onto the flex cable and cause potential data corruption or unwanted electromagnetic inference, EMI.
Power Sequencing*
The decode engine is powered from the VIN power signal on the ZIF connector on the decode board. Most of the host signals (signals present on the ZIF connector) are relative to this voltage. Not all of these signals are overvoltage tolerant thus; care must be taken to ensure that the relationship between the VIN and the host signals are always met (see electrical specifications on page 34).
Thermal Considerations
The decode engine is qualified over the specified operational temperatures (0°C to 40°C) for all operating modes. Make sure ambient temperatures do not exceed this range in order to guarantee operation. Operating the decode engine in continuous mode for an extended period may produce considerable heating. This mode should be limited and sufficient airflow should be provided whenever possible to minimize internal heating.
Excessive heating may degrade images and potentially damage the engine.

See pages 38 and 42 for additional information on the engine pinouts and flex cable pinouts.

Theory of Operation
Overview
The IS4920 decode imaging engine series is ideal for integration into data terminals and other small devices.
The high-quality images produced by the imaging engine can be used for decoding bar codes, image upload, signature capture, document lifting and reading OCR fonts.
The decode engine consists of two main system components: the a non-decode imaging engine, which utilizes a high-resolution CMOS image sensor, and a small decode board that contains a powerful microprocessor and the firmware to control all aspects of the engine’s operations and enabling communication with the host system over the standard set of communication interfaces.
The model IS492x-xx103 provides communication with the host system over TTL-level RS232 communication interface.
The model IS492x-xx38 provides communication with the host system over USB. It can be configured for the following protocols of USB communication:
• USB Keyboard Emulation Mode (default)
• USB Serial Emulation Mode
The system hardware architecture of the decode engine is shown in the figure below.

17
Since many host systems and applications have unique formats and protocol requirements, the decode engine supports a wide range of configurable features. These features may be selected by scanning a corresponding configuration bar code from the MetroSelect Single-Line Configuration Guide or Area Imaging Bar code
Supplemental Configuration Guide. Both guides are available for download at www.honeywell.com/aidc under the IS4920 product page.
Usage of the Host Interface Signals
In the default “multi-try” trigger mode of operations, the scanning engine is activated by the nTrig signal, which must be kept active (low) until the successful scan is achieved, as indicated by the nGoodRead signal.
Upon a successful scan, the decode engine asserts the nGoodRead signal and keeps it asserted (low) for the duration of transmission of the decoded data to the host, or for the minimum of 100 msec (configurable to 50 msec), which coincides with the duration of the nBeeper signal.
The nGoodRead and nBeeper signals are driven with LVC family open drain outputs and are pulled up on the decode board with 100K resistors to VIN. The default state of these pins is Hi-Z (pulled up via 100K) and these signals are capable of sinking up to 24mA each when driven to the low state. For beeper applications, care must be taken to ensure that inductive spikes do not cause the voltage on the lines to exceed the maximum voltage of 5.5V.
Warning: The nGoodRead and nBeeper signals are not current limited. The external host circuitry connected to these pins must ensure that the current is limited to 25mA.
At any given time, the decode engine can be in one of the following power modes, see page 20 for descriptions:
• Boot Mode
• Operating Mode
• Idle Mode
• Sleep Mode
• Presentation Wakeup Mode
• Power-down Mode (TTL Only)
• Suspend Mode (USB Only)
When the decode engine is in the Sleep or Presentation Wakeup Mode, the nWake or nTrig signals can be used to wake up the engine.
The nWake signal wakes up the engine and turns the engine into the Idle Mode, which in the TTL RS232 version enables communication with the host for a short period of time defined by the value of the sleep timeout, which is set to one second by default.
Note: In the USB decode engines with USB Serial Emulation Mode activated; communication with the host is enabled even when the engine is in the Sleep or Presentation Wakeup Mode.
18
The nTrig signal not only wakes the engine up, but also immediately activates and turns the engine into the
Operating Mode.
Either nWake or nTrig signals can be used to restart the TTL RS232 scanning engine when the engine is in
Power-down Mode, which is indicated by the asserted (high) PWRDWN signal.
The PWDWN pin is used to indicate when the decode engine is in various operating modes such as Power
Down, Suspend, and Boot.
Note: The output signals from the decode engine can experience analog behavior when VIN is initially applied or removed due to the supply voltage ramping up or down. Care must be taken to ensure that this behavior does not adversely affect the host System. Special attention must be given to the PWRDWN
Pin. When power is initially applied, the output state of this line will be indeterminate for about 10mS until the USB controller exits reset. The state of this pin should be disregarded during this time. The following waveforms show several signals when VIN is first applied (Figure 17) and when VIN is removed (Figure 18).

• The engine can be turned to Suspend Mode any time (by the USB host).
The engine can wake up from Suspend Mode and reboot:
• Upon receiving the Resume signal from the USB host.
21
Serial Configuration
The IS4920 series can be configured by scanning configuration bar codes
†
or by serial commands sent from the host device. With serial configuration, each command sent to the engine is the ASCII representation of each numeral in the configuration bar code (see Figure 19). The entire numeric string is framed with an ASCII
[stx] and an ASCII [etx].
Do Not Include in the Command
³ 1 0 0 1 0 4
Include in the
Command
Figure 19.
Example 1:

String Sent to the Engine - ASCII Representation (Hexadecimal Values)
02h 31h 30h 30h 31h 30h 34h 03h
If the command sent to the engine is valid, the engine will respond with an [ack]. If the command sent to the
engine is invalid, the engine will respond with a [nak] then automatically exit serial configuration mode. All the
settings chosen in the failed serial configuration session will be lost. There is a 20-second window between commands. If a 60-second timeout occurs, the engine will send a [nak].
To enter serial configuration mode, send the following command, [stx]999999[etx]. The engine will not scan bar codes while in serial configuration mode.
Note: Serial configuration mode uses the current Baud Rate, Parity, Stop Bits and Data Bits settings that are configured in the engine. The default settings of the engine are 9600 bits-per-second, no parity,
1 stop bit, 8 data bits, and no flow control. If a command is sent to the engine to change any of these settings, the change will not take effect until after serial configuration mode is exited.
To exit serial configuration mode, send the following command, [stx]999999[etx]. The engine will respond with an [ack]. Refer to Example 2 on page 23.

The waveforms shown in this section assume VIN = 3.3V, nGoodRead pulled up with 10K resistor to VIN, and nBeeper pulled up with 10K resistor to VIN, unless otherwise noted.
Power Up / Boot Up
The power up sequence of the decode engine depends on the interface type. For the USB version, a USB
Microcontroller controls the power to the decoding platform and imaging engine via a power switch. When power is initially applied, only the USB controller is active and begins the process of enumeration. Once enumeration is complete, the USB controller turns power on to the imaging engine and decoding platform. As a result, powering up the engine is completely controlled by the on board USB controller per the USB specifications. In this version, only Idle and Sleep Modes are supported. For additional power savings, the unit must be placed in Suspend Mode per the USB specification. Figure 20 shows the power up sequence of the
USB version of the decode engine.
Note: The PWNDWN signal remains high until the Decode platform transitions to Idle Mode and is ready to accept commands. In the USB version, the PWNDWN Pin will only be high during this boot up condition or when the Decode enters, Suspend Mode. From Figure 20 , it can be seen that the entire boot up sequence takes approximately nine seconds.
Figure 20. Power Up / Boot Up Sequence of USB Version
24
The TTL version of the decode engine does not have an on board microcontroller to control the power to the decode platform and imaging engine. As such, the TTL version can only enter Boot Mode in response to signals from the host (nTrig or nWake). When VIN is initially applied with the nWake and nTrig signals held high, the unit will be in the Power Down Mode. In this state, the PWRDWN signal will be high and all other output signals will be in their default state. By bringing either the nTrig or nWake signal low, power will be applied to the entire system and the unit will enter the Boot Mode. The nTrig or nWake signal will need to be held low continuously for approximately two seconds at which time the decode engine will take control of the internal power circuitry. At this point, the nTrig and nWake signals can be used with out interrupting the power.
Figures 21 - 23 show the state several host signals when power is first applied and when the unit enters boot mode.
Note: The default state of TxD depends on the 232INV signal. When 232INV is low, the default state of TxD is high. When INV is high, the default state of TxD is low.

Figure 23. Transmit and RTS during Boot
Up forTTL Version (Vin= 5V)
25
Notes: In Figure 21 , the nGoodRead, nBeeper, and PWRDWN signals are high while in the Power Down
Mode.
The RTS Signal will be high in Power Down Mode regardless of the RTS polarity software configuration. Also, the RTS signal may have the incorrect polarity when the device first enters Boot
Mode (Figure 23) or right before the unit enters Power Down Mode (Figure 24).
The USB version can be placed into Suspend Mode via the USB suspend signal for low current consumption.
When this occurs, power to the decoding platform and imaging engine is removed. While in this state, nBeeper and nGoodRead will be in their default state (Hi-z with weak pull up). PWRDWN will be high and the
USB data lines will be in the Suspend Mode.
Power Down / Suspend / Power Removed
At any time VIN can be completely removed from the decode engine however, care must be taken to avoid removing power during the boot up, flash upgrades, or configuration updates. Removing power during these times can result in the corruption of the flash memory. Figure 18 shows several host signals during a power removed condition for the USB version.
The TTL version enters into the Power Down Mode in which power to the decoding platform and imaging engine is removed. The decoding processor can initiate a Power Down sequence after a programmable time period has elapsed without any activity. Figure 24 shows the TxD, RTS, VIN, and PWRDWN signals when the
TTL enters into Power Down Mode.
Figure 24. Power Down for TTL
26
Decode Timing
Engine image acquisition or decoding can occur from either the Idle Mode or the Sleep Mode. The process is initiated by asserting the nTrig signal (or serial command when in the Idle Mode). Once the trigger signal is received, the image sensor is reset and image acquisition begins. During image acquisition, the illumination
LEDs are enabled for a time determined by the FirstFlash circuitry on the non-decode engine. The image is then transferred to the processor and decoded. Upon decoding the image, the processor asserts the nGoodRead signal (low) and beings transmitting the decoded data. When the decode engine receives a trigger signal while in the Sleep Mode, an additional delay is needed for the processor exit Sleep Mode and reconfigures the sensor.
Figure 25 and Figure 26 show the amount of time required for decoding when a nTrig signal is asserted in both the Idle Mode and Sleep Mode.
Notes: The total image acquisition / decode time can be approximated by measuring the time from the nTrig signal going low to the nGoodRead signal going low. This time will vary slightly based on several factors including code quality, code type, and distance from the engine. The following waveforms show a typical condition.
The nTrig signal must be kept low for at least 20msec.

EMI
The IS4920 consists of a 400MHz processor running a 100MHz SDRAM bus and a camera interface capable of image transfer up to 48MHz. The IS4920 series engine was designed to meet EN55022 Radiated Class B emission limits. Using the system shown below, the decode engine was able to meet these requirements with an input voltage VIN = 3.3V and the camera interface operating at its maximum frequency of 48MHz.
