About This Guide Introduction The SE4400 Integration Guide discusses the theory of operation, installation, and specifications of the engine, and how to integrate the engine into data capture devices. Note: This guide provides general instructions for the installation of the engine into a customer's device.
SE4400 Integration Guide Notational Conventions The following conventions are used in this document: • Bullets indicate: • action items • lists of alternatives • lists of required steps that are not necessarily sequential • Sequential lists (e.g., those that describe step-by-step procedures) appear as numbered lists.
Chapter 1 Getting Started Per FDA and IEC standards, the engine described in this guide is not given a laser classification. However, the following precautions should be observed: Caution This laser component emits CDRH Class II/IEC Class I laser light. Do not stare into beam.
SE4400 Integration Guide SE4400 The SE4400 contains: • a monochrome VGA charge coupled device (CCD) imager system • a laser-based aiming system • an illumination system • a motor drive for changing focus position • ample signal processing to provide an 8-bit data output (grayscale) for each pixel of the CCD sensor array.
Getting Started A 31-pin ZIF connector on the SE4400 connects the engine and the device via a 40 mm flex (available from Symbol, p/n 50-16000-650, via KT-SE4400-01). For information about this connector and flex, see Figure 4-1 on page 4-4 Figure 4-3 on page 4-6.
SE4400 Integration Guide Aiming Control The aiming subsystem is under dynamic software control and is independent of the illumination subsystem. The SE4400 can capture images with both the aiming subsystem turned on (the image of the aiming pattern is captured in the digital image) and the aiming subsystem turned off. Illumination System An illumination subsystem, consisting of one red 635 nm LED, is provided to meet the image capture and decoding requirements throughout the full range of ambient lighting...
Chapter 2 Installation Overview This chapter provides information for mounting and installing the SE4400, including physical and electrical considerations, and recommended window properties for the SE4400. General Information Grounding The chassis is at ground. Isolate the SE4400 and host if installing the engine to a host that is not at ground, or has ground with the potential to inject noise.
SE4400 Integration Guide Mounting There are two mounting holes (M1.6x0.35) and two locator holes on the bottom of the chassis (see Figure 2-1). The SE4400 can be mounted in any orientation without degradation in performance. Note: Mounting the SE4400 in a non-upright position results in images rotated accordingly in snapshot or video mode.
Page 19
Installation Notes: Unless otherwise specified: • Chassis is at ground. • Nominal aiming pattern envelope is 30 x 22.5 • Nominal imaging FOV envelope is 32 x 24 • Nominal illumination envelope is 40 cone. • Maximum envelopes do not include integration tolerances. •...
SE4400 Integration Guide Housing Design Note: Opto-mechanical analysis is recommended for housing design to ensure optimal scanning or imaging performance. Design the housing so that internal reflections from the illumination system are not directed back toward the engine. The reflections from the window can cause problems, and for particular window tilt angles, these reflections can bounce off the top or bottom of the housing and reach the engine.

Installation or without an anti reflection coating, depending on the application). Following are descriptions of three popular window materials: PMMA, ADC (CR-39 ), and chemically tempered float glass. Table 2-1 outlines the suggested window properties. Table 2-1. Suggested Window Properties Material Clear cell-cast acrylic Thickness...
SE4400 Integration Guide 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. However, they are expensive and have very poor abrasion and scratch resistance.
Installation A Word About Coatings In all cases, adhere to the minimum tilt angle specified in Table 2-4 on page 2-9. When the SE4400 is set to an exposure time less than 10 milliseconds and gain less than 127, anti- reflection coating is not necessary (see Exposure &...

Chapter 5 Application Notes Overview This chapter includes image acquisition and power consumption information. Image Acquisition The SE4400 CCD is a monochrome VGA resolution sensor. The pixel area, shown in Figure 5-1, is composed of 680 horizontal pixels and 492 vertical pixels; however the actual area upon which light is gathered is slightly smaller (652 x 486 pixels).
Page 60
SE4400 Integration Guide *OBP = Optically Blocked Pixels, which are not photosensitive. Figure 5-1. Pixel Layout To operate properly, the CCD chipset requires a clock near 24 MHz. To achieve this, an internal PLL multiplies the incoming 12 MHz MCKI by two to generate the 24 MHz internal camera clock, MCK.
Application Notes Note: Clock details apply for the I C settings provided in Appendix A, Register Settings. For alternate clock scenarios, refer to LC99704B- WK3 Sanyo DSP Specification, Version 1. The operating settings, stored in the SE4400’s on-board DSP registers, are programmed using the I C interface developed by Philips.
Page 62
SE4400 Integration Guide the Vcc supply voltage cannot meet this rise time requirement, bring REG_RES* low by external means for a minimum of 500 µs. After a successful reset, the I C registers contain default parameters that place the SE4400 in stand-by mode. Initialize the SE4400 with the register values listed in Table A-1 Table A-2.
SE4400 Integration Guide Image Acquisition Procedure Figure 5-3 summarizes the Mode 3 imaging acquisition procedure. Table 5-1 provides a summary of the Mode 3 input and output signal functions. The CCD is exposed to light during the time that EXSFT is low. This exposure time must be an integer multiple of line times "H", unless it begins after the negative edge of VREF, in which case this time is not restricted.

Application Notes Mode 1 Startup Procedure Figure 5-4 for the Mode 1 startup procedure timing diagram. The Vcc supply voltage and REG_RES* reset line requirements are the same in Mode 1 as in Mode 3. After a successful reset, the I C registers contain default parameters that place the SE4400 in stand-by mode.
Application Notes Image Acquisition Procedure Figure 5-5 summarizes the Mode 1 imaging acquisition procedure. Table 5-2 summarizes the Mode 1 input and output signal functions. As with Mode 3, VREF and HREF indicate the reading of valid vertical and horizontal pixel data, respectively.
Application Notes Power Modes The SE4400 supports five power modes, defined in Table 5-3, which offer trade-offs between power consumption and image acquisition time. Table 5-3.

Page 72
SE4400 Integration Guide • To enter Mode D, halt the acquisition of the 8-bit pixel data. The recovery time for this mode can vary from 66 ms down to 33 ms, depending on how near the exit of Mode D is to the end of the frame (if it occurs immediately prior to the end of the frame, the recovery time is 33 ms).

SE4400 Integration Guide Motor Control The SE4400’s lens system can be dynamically set to near or far focus positions: • The near focus allows the SE4400 to focus on objects that are about five inches away. • The far focus allows the SE4400 to focus on objects that are about nine inches away.

Application Notes auto-exposure mode unless Address 130d[2] is set to 0. For more information concerning auto-exposure, refer to LC99704B-WK3 Sanyo DSP Specification, Version 1. Digital and analog gain controls can be varied over the I C interface. Use both the digital and analog gain to achieve a maximum gain of over 30 dB.
SE4400 Integration Guide Power Consumption Figure 5-8 segments the current profile into 7 divisions of time. See Table 5-5 for details of this segmentation. These measurements were taken with the motor disabled and the illumination and aiming turned off. The results apply to both Mode 1 and Mode 3 operation. Figure 5-8.
