    This device emits CDRH/IEC Class 2 laser and IEC Class 1M light. Do not stare into beam. Introduction The JE-227 captures digital images for transmission to a decoder to decode a bar code of any format supported by the decoding software. The JE-227 uses laser aiming and LED illumination.

  • Page 12: Aiming System

    Aiming JE-227 Block Diagram Figure 1-1 A 21-pin ZIF connector on the JE-227 connects the engine and the host device via a 55 mm flex (available from JADAK). For information about this connector, see Figure 4-1 on page 4-3. Also see...

  • Page 13: Aiming Error

    Frame Rate Control The JE-227 outputs images at 54 frames per second by default. When capturing images, use lower frame rates to increase image brightness. The aiming pattern appears to blink when the frame rate is 30 fps or lower.

  • Page 14: Chapter 2 Installation

    This results in decode performance degradation and should be avoided. Grounding The chassis is at ground. Isolate the JE-227 and host if installing the engine to a host that is not at ground, or has ground with the potential to inject noise.

  • Page 15: Electrostatic Discharge (Esd)

    As a protective measure for the laser diode, at extreme temperatures the JE-227 first shuts off the laser and dims illumination (at 68°C chassis temperature). Illumination shuts off at 72°C. As the engine temperature returns to normal levels the laser and illumination power returns to nominal values.

  • Page 18: External Optics (Imaging Lens, Illumination Leds, And Aiming Element)

    External Optics (Imaging Lens, Illumination LEDs, and Aiming Element) Do not subject external optical components on the JE-227 engine to any external force. Do not hold the engine by an external optical component. This can place excessive stress in the mechanical joints that secure the components, which can cause failures such as joint cracking or breaking.

    •Holes marked "A#" are engine locating aides. Holes marked "B#" are threaded mounting holes. Slot marked "C" is JE-227-SR LSR AIM specific locating aid. •It is recommended to secure the engine using a combination of two locating pins and two mounting screws which must include A1 and B1.

  • Page 20: Optical

    2 - 7 Optical The JE-227 uses a sophisticated optical system that provides imaging performance that matches or exceeds the performance of much larger imagers. However, an improperly designed enclosure, or improper selection of window material, can affect the performance of the JE-227.

  • Page 21: Commercially Available Coatings

    Installation 2 - 8 When using plastic materials pay extra attention to the wavefront distortion recommendation specified above. Colored windows are not recommended because they can significantly degrade performance of the white illumination system and adversely affect cellphone reading mode. Cell Cast Acrylic (ASTM: PMMA) Cell Cast Acrylic, or Poly-methyl Methacrylic (PMMA) is fabricated by casting acrylic between two precision sheets of glass.

  • Page 51 C is a master/slave protocol, meaning the host initiates both transmissions. The JE-227 typically processes a command in less than 1 ms, but some commands take up to 100 ms. For this reason, after sending a command, the host (I C master) should request a response, and if the JE-227 does not respond the host should retry the response request for up to 100 ms.
