    This device emits CDRH/IEC Class 2 laser and IEC Class 1M light. Do not stare into beam. Introduction The SE4750 captures digital images for transmission to a decoder to decode a bar code of any format supported by the decoding software. The SE4750 uses laser aiming and LED illumination.

    Aiming SE4750 Block Diagram Figure 1-1 A 21-pin ZIF connector on the SE4750 connects the engine and the host device via a 55 mm flex (available from Motorola). For information about this connector, see Figure 4-1 on page 4-3. Also see...

  • Page 17: Aiming System

    Frame Rate Control The SE4750 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 19: Chapter 2 Installation

    This results in decode performance degradation and should be avoided. Grounding The chassis is at ground. Isolate the SE4750 and host if installing the engine to a host that is not at ground, or has ground with the potential to inject noise.

  • Page 20: Electrostatic Discharge (Esd)

    As a protective measure for the laser diode, at extreme temperatures the SE4750 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 23: 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 SE4750 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.

  • Page 24: Mounting

    2-4). The SE4750 can be mounted in any orientation without degradation in performance. NOTE Mounting the SE4750 in a non-upright position results in images rotated accordingly in snapshot or video mode. When installing the mounting screws, ensure they do not protrude past the mounting hole threads in the chassis;...

  • Page 25: Housing Design

    Consider using baffles or matte-finished dark internal housing colors. Optical The SE4750 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 SE4750.

  • Page 26: Window Material

    2 - 8 SE4750 Integration Guide Window Material Many window materials that look clear can contain stresses and distortions that reduce performance. For this reason, use only cell-cast plastics or optical glass (with or without an anti reflection coating, depending on the application).

  • Page 27: Commercially Available Coatings

    Installation 2 - 9 Commercially Available Coatings Anti-Reflection Coatings Anti-reflection coatings can be used for stray light control or to achieve maximum working range, and can be applied to the inside and/or outside of the window to reduce the amount of light reflected off the window back into the engine.

Specific power-up and power-down sequences of these three supplies are recommended to ensure proper operation. Power-up During power-up, the VCC supply ramps up before or at the same time as the VCC_ILLUM and VCC_IO_HOST supplies.

  • Page 57: Transactions

    C is a master/slave protocol, meaning the host initiates both transmissions. The SE4750 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 SE4750 does not respond the host should retry the response request for up to 100 ms.

  • Page 58: Command Checksum

    5 - 4 SE4750 Integration Guide Command Checksum Every command must include a checksum, calculated as follows: Sum the bytes in the command, starting from the opcode through the last command data byte. Use only the low byte of this result.

  • Page 59: Command Descriptions

    After receiving the Stop command, the SE4750 may not respond to subsequent commands for up to one frame time (16.6 ms at 60 fps) because the system requires the current frame to complete before the engine processes new commands.
