  • Page 15: Chapter 1 Getting Started

    Introduction The SE4710 is a sub-miniature area imager engine optimized for bar code reading. The engine captures digital images of a bar code for transmission to a decoder to decode a 1D or 2D bar code of any format supported by the decoding software.

  • Page 16: Se4710

    SE4710 Block Diagram Figure 1-1 A 27-pin ZIF connector on the SE4710 allows connection of the engine and the host device via a 3.52 in (89.4mm) flex strip. The flex is available from Motorola. For information about this connector, see Figure 4-1 on page 4-3.

  • Page 17: Aiming System

    In this case, ensure ambient illumination provides a minimum of 30 fcd on the document surface. See also Thermal Considerations on page 2-2. Frame Rate Control The SE4710 outputs images at 30 frames per second by default. The SE4710 can also output images at 60 fps, but at reduced frame size (640 x 400).

  • Page 19: Chapter 2 Installation

    General Information Default Power Mode The default power mode for the SE4710 when connected to a PL3307 decoder is Bus-Powered USB Mode (<500mA). If operating in Self-Powered USB Mode (>500mA) or RS-232 Mode with VCC_ILLUM =3.3V, configure the PL3307 for one of these modes using config 0 and config 1 signals.

  • Page 20: Environment

    In a thermal chamber with zero air flow and no heat sink attached, the thermal dissipation of the SE4710 engine can be simplified as the lumped capacitance thermal model shown in Figure 2-1.
  • Page 21 Installation 2 - 3 Based on this lumped capacitance thermal model and the engine power consumptions (see Table 3-7 on page 3-7), the allowed engine scanning duty cycles can be calculated and plotted for a defined engine chassis temperature limit as Figure 2-2 Figure 2-3.

  • Page 23: External Optics (Led Lenses And Pattern Forming Element)

    External Optics (LED Lenses and Pattern Forming Element) Do not subject external optical components on the SE4710 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: Se4710 Integration Guide

    There are several mounting holes (M1.4x0.3) and locator holes on both the top and bottom of the chassis (see Figure 2-4). The SE4710 can be mounted in any orientation without degradation in performance. 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 SE4710 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 SE4710.

  • Page 26: Window Material

    2 - 8 SE4710 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 49: Chapter 5 Control Interface

    Captures the aim pattern in the image. AIM_POWER 0xF3 Sets the aim brightness. AUTO_POWER_REDUCTION 0x74 Places the SE4710 in a low power state when idle. DRIVE_STRENGTH 0x99 Sets the output drive strength of the parallel interface based on host integration, and VDD_IO_HOST voltage level.
  • Page 50 Reads the OmniVision OV9212 registers. RESET 0x57 Returns engine components to a default state. TIME_TO_LOW_POWER 0x75 Sets the length of time the SE4710 is idle before entering low power mode. WR_SCRIPT 0x76 Programs more than one SE4710 command into one 5-10 script.

  • Page 51: Transactions

    C is a master/slave protocol, meaning the host initiates both transmissions. The SE4710 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 SE4710 does not respond the host should retry the response request for up to 100 ms.

  • Page 52: Command Checksum

    5 - 4 SE4710 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 53: Command Descriptions

    I C retry before the time specified by TIME_TO_LOW_POWER. The SE4710 is considered idle only if acquisition is stopped and aim is off. While acquisition is started, or aim is on, the SE4710 does not automatically enter low power mode.

  • Page 54: Enter_Bootloader 0X91

    It is up to the host to determine the correct drive strength level based on signal integrity and electromagnetic compatibility requirements. The default is 3.3V low. ENTER_BOOTLOADER 0x91 In this mode, the SE4710 protocol changes and no longer supports this I C command set. Bootloader mode is necessary for firmware updates.

  • Page 55: Get_Extended_Status 0X79

    5 - 7 GET_EXTENDED_STATUS 0x79 The SE4710 internally tracks various operating states and stores these states in the extended status structure. This command gets these states from the SE4710. The following are the operating conditions and descriptions. Each operating condition has 2 bits in the extended status: •...

  • Page 56: Illumination_Power_Level 0Xf0

    ILLUMINATION_POWER_LEVEL 0xF0 Sets the SE4710 illumination power (brightness) level. The valid ranges are from 1 to 27. The default is 7, or 100mA. Each count is in 12.5mA increments. It is not recommended to go below 7 due to the non-linearity of the illumination LED response.

  • Page 57: Picklist_Mode 0X7B

    Reads directly from the OmniVision OV9212 sensor registers. Refer to the OV912 specifications from OmniVision for register descriptions. RESET 0x57 Returns the SE4710 to a default state. TIME_TO_LOW_POWER 0x75 Sets the length of time the SE4710 must be idle before it enters low power mode. This only applies if AUTO_POWER_REDUCTION is enabled.

  • Page 58: Wr_Script 0X76

    5 - 10 SE4710 Integration Guide WR_SCRIPT 0x76 Programs more than one SE4710 command into a script, which can be executed using a single command (EXECUTE_SCRIPT). Use this method whenever possible to increase performance and timing synchronization. There are ten scripts (Script-0 through Script-9) and a total of 150 bytes for all scripts. Exceeding these limits results in a NAK status code.

    Recommended Procedures The following trigger mode procedures describe the recommended transaction sequence between a host and the SE4710. These transaction sequences use discrete commands for clarity. Replace any set of discrete commands with a multi-command EXECUTE_SCRIPT to improve throughput. System Initialization The host sends the IMAGER_INTERFACE_TYPE command to configure the desired interface.
