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

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 60-4

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 reduc

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

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 se

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

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
