Introduction Product Overview The IS4910 series of non-decode miniature area imaging engines is designed for integration into customer ® OEM devices. When integrated with a host processor and decoding software from Omniplanar , the engine can be used to capture images for decoding 1D and 2D bar codes in addition to OCR fonts. The compact engine has several models available to accommodate all types of mounting requirements.

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.
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.
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. IS4910 Figure 7. IS4910 Optical Clearance Specifications IS4911 Figure 8. IS4911 Optical Clearance Specifications Specifications are subject to change without notice.
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.
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.
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.
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.
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.
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 2 suitable for high ambient light applications. The Video Mode is initiated through commands via the I 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.
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.
