About the DE2011-DL The Datalogic DE2011-DL is a very compact, high performance undecoded imager used to capture digital images to be transferred to an external digital platform, to provide the ability to decode any kind of bar code symbols. Unpacking the Scan Engine The scan engine is shipped in custom packaging. Carefully open the pack-
age, and inspect for the following:
scan engine interface cable (if ordered) If any parts are damaged or you need additional hardware, please contact Technical Support. Scan Engine Care The scan engine contains sensitive components which require special han-
dling. Datalogic may not warrant damage due to improper handling. Do not disassemble the scan engine. Doing so will void the warranty. Use standard ESD precautions & policies when handling the DE2011-DL scan engine. External Optics The engine has an exposed illumination system and aiming lenses on the outer surfaces. Take care of these optical components, preserving the lenses from mechanical stresses that can damage them. Avoid touching the optical surfaces to preserve the optical performance. 2 DE2011-DL System Overview About the DE2011-DL The Datalogic DE2011 scan engine features a global shutter sensor having 752x480 pixels, able to capture images at 60 frames per second. The engine contains an embedded illumination system and an aiming sys-
tem. A high performance, low power micro-controller runs the engine sys-
tem and handles communication with the external host. The host interface is available as a 21-pole zif connector. Figure 1. Engine block diagram Illumination System The Illumination System is comprised of two white LEDs and non-imaging optics designed to provide first-class reading performances, even in total darkness. Regulatory EN/IEC 62471 (exempt) Aiming System The aiming system is based on a 650nm laser diode and related optics. It projects a highly visible 4-Dot aimer with center-cross for targeted scan-
ning. Integration Guide 3 Introduction Aiming Pattern The central cross represents the center of the field of view, while the four dots show the boundaries of the field of view. Figure 2. Projected pattern at 200 mm Aiming System Parameters Wavelength Beam Divergence Maximum pulse duration 630-680 nm 35 (horizontal) x 25 (vertical) see Figure 8 on page 11 and Figure 9 on page 11 15ms Repetition rate 16.6ms Maximum output power Laser aperture 1mW See Figure 10 on page 12 Regulatory EN/IEC 60825-1:2007 (class 2) 21 CFR 1040 (CDRH) (class II) Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a dis-
tance of 100mm may pose an eye hazard. WARNING 4 DE2011-DL Figure 3.

stat la suite dune exposition au rayon laser. Eviter de regarder fixement le rayon, comme toute autre source lumineuse intense telle que le soleil. Eviter aussi de diriger le rayon vers les yeux dun observateur, mme travers des surfaces rflchissantes (miroirs, par exemple). WARNING ATTENTION Integration Guide 5 Introduction NOTES 6 DE2011-DL Chapter 2 Installation This section describes how to design the mounting for optimum scan engine performance. Mounting the Scan Engine General Considerations A typical system uses the scan engine mounted inside a host enclosure, with an opening for the illumination system light to exit and illuminate the label, and to read bar codes. The opening should be the size of the scan engine field of view at a minimum, but only exposing as much of the scan engine as necessary. It is important to consider the effect of the environment on the scan engine. In particular, mounting should minimize the possibility of foreign objects coming into contact with the electronics. Such contact could damage the device or reduce the scan engines performance. Mechanical Size Figure 4 Nominal size:
21.0mm (width) x 11.4mm (height) x 15.75mm
(depth)
. Nominal Engine Size Maximum size:
21.15mm (width) x 11.55mm (height) x 15.91mm (depth) Integration Guide 7 Installation Mounting Holes There are three mounting holes M1.6x0.35mm located on the bottom of the chassis. The recommended thread engagement for the screws is 1.7mm
(holes marked with A), with a mounting torque of 0.15Nm. Figure 5. Mounting holes and related requirements Housing Design The enclosure must be designed to prevent internal reflections from illumi-
nation and aiming systems into the receiving optics.The exit window must be properly positioned and tilted to avoid reflections that could limit engine performance, both for decoding and image capture. Positioning the exit window There are two options for positioning the exit window with respect to the engine optical axis:
Perpendicular Tilted Distances are measured from the illumination lenses to the first face of the exit window (the nearest to the engine). Window thickness should be smaller or equal to 1.5mm. The use of a double-sided AR coated exit window is strongly recommended both for perpendicular and tilted windows. 8 DE2011-DL Figure 6. Exit window positioning perpendicular window Mounting the Scan Engine Figure 7. Exit window positioning tilted window Avoiding scratched windows Scratches on the exit window can strongly affect the reading performance. It is recommended to use an exit window having a scratch-resistant coating and to position the engine window in a recessed position. Window material The exit window is an integral part of the imaging system and should be designed and selected to preserve the optical quality of the system. It is rec-
ommended to use only cell-cast plastics or optical glass. Common materials and their characteristics are shown in Table 1on the fol-
lowing page. Integration Guide 9 Installation Properties Table 1. Exit window materials PMMA

Front View - Laser aperture Environment Dust on the optical parts of the engine can badly affect the performance of the scan engine. Ensure the engine is clear of dust and water when integrat-
ing it inside the housing. 12 DE2011-DL Chapter 3 Electrical Integration Electrical Connections Grounding The chassis of the engine is at ground. Mounting screws can be used to implement additional connections to the host ground. Based on the host characteristics, the additional ground connections can affect:
the engine performance (if noise is injected into the scan engine) the radiated emission (depending on current loops) It is suggested to investigate these topics at the beginning of the integra-
tion. ESD The engine is protected from ESD up to 2.0Kv@ connector. During installation it is recommended to apply standard ESD handling pro-
cedures, such as operating in a properly grounded working area using wrist straps. Electrical Interface The DE2011-DL scan engine can be connected to an external digital plat-
form via a 21-pole ZIF connector supporting:
a parallel video port (8 bit per pixel, vertical and horizontal synchs, pixel clock) a signal to synchronize an external illumination system with the expo-
sure of the sensor (Flash_out) system) three dedicated power supplies (for sensor, digital system, illumination an I2C communication port for controlling the scan engine Table 3 below describes the power lines and the signals mapped on the 21-

For further details and requirements related to the flat cable, please refer to the manufacturers datasheet, available athttp://www.kyoceraconnec tor.com/prdct/type/fpc/index.html#2 Powerup sequence In order to guarantee the correct operation of the engine, it is mandatory to use the following powerup sequence timing constraints:
VDD_SENSOR must be stable at 3.3V not later than 6ms after the VDD is VDD_ILLUM_SYS must be stable at 3.3V at least 20ms before issuing any camera start command. Engine latency at powerup At powerup the engine begins executing the code when the power supply level reaches 2.1V. To complete the boot sequence, a 12ms time is required. After this, the engine is ready to parse commands. at 2.1V. 14 DE2011-DL Electrical Interface Supply Voltages and I/O levels Table 4.

The value of 3.0V has to be considered as an inferior limit, but for having superior power supply noise immunity, a value above 3.15V is rec-
ommended The digital and laser aiming system power supply. The LED illumination system power supply. The typical high level for input and output signals. Power supply noise To preserve image quality (both for decoding and image capture applica-
tions), a low-noise power supply is required, particularly for VDD_SENSOR. The requirement for the power supply peak-to-peak noise is 150mV on all three power supply lines (the lower the better). Integration Guide 15 Electrical Integration NOTES 16 DE2011-DL Chapter 4 Software Interface Communication Protocol The engine provides a bidirectional control interface for the communication with the integrating platform based on the I2C communication. This is a master/slave and host-initiated command/response type of protocol, and the engine always acts as a slave. It does not support unsolicited responses, meaning that all transactions that involve sending a command and receiving a response are always initiated by the host system. The time needed for execution depends on the command sent. If the engine does not respond when requested by the host, it is possible that the com-
mand is still being processed. In this case, the master will be forced into a wait state until the slave is ready. The maximum waiting time between receiving a command and the response request is 1 second. After this time a system timeout occurs and the engine will reset. Command Format Commands sent via I2C from host (master) to engine (slave) should have the following format:
Start bit Address Command
(hex code) Command Parameters Checksum Stop bit I2C Element Start bit:

Integration Guide 27 Technical Specifications Power Consumption Details While operating, the engine switches between different status conditions. Each status is characterized by a specific power consumption level. Low power Idle Running The engine is in sleep (minimum power consumption) The engine is active, waiting for commands and ready to start an acquisition The engine is acquiring and streaming images to the host. Power consumption depends on the configuration of the engine Assuming the system is at 23C and all three power supplies are at 3.3V, the typical current absorption is reported in the table below (engine parameters set at factory default).

For a summary list and more information, see Command Format, starting on page 17. AIM TIME (0x4E) Determines the lighting time of the aiming pattern during each frame, starting from after the sensor exposure. A longer period determines a brighter aim pattern. Accepts values from 0x1 to 0xFF; each unit corresponds to a 0.5 ms time increment. If set to 0x0, sets the time to a default value, which can be also determined by the user modifying the parameter AIM DURATION (see Table 7 on page 24) Whichever value is set, for each frame the aim on time might be automatically trimmed in order to be off during the sensor expo-
sure. AIM TOGGLE (0x35) With the value set to 0x01 the aim pattern will turn on whenever the camera is acquiring images. Setting the value to 0x00 will always turn it off. The aim pattern will not be visible in the acquired images. AUTO LOW POWER (0x44) Activates system automatic power saving mode, turning the system into low power mode after a timeout. When the camera is continuously idle for a time, previously determined using the SET AUTO POWER TIME command, the system enters a power reduction state. When an I2C command is issued the system wakes up and executes the command. BOOTLOADER START (0x41) Stops executing the engine camera application and runs the engine bootloader. Takes as input the following signature code: 0xAA, 0x50, 0x5. CAMERA MODE (0x3B) Sets up the engine system and the image sensor for better performance of a specific task: Barcode Decoding, Image Capture, Motion Detection, Fast High Bin or LCD screen Read modifying sensor internal register values, LED illumination and aiming pattern on/off timing. This command modifies only some key engine and sensor parameters, leaving others unchanged. The parameters changed by this command are:
30 DE2011-DL CAMERA MODE (continued) I2C Command Specifications ILLUMINATION TIME ILLUMINATION DELAY AIM ON TIME AIM DELAY IMAGE BINNING SENSOR CONTEXT SENSOR AEC MAX EXPOSURE DESIRED BIN SENSOR ACTIVE CONTEXT (A/B) Barcode Decoding, Image Capture and LCD Screen Read operate using sensor Context A, while Motion Detection and Fast High Bin operate using sensor Context B with a 2xColumn+2xRow binning. CAMERA RESET (0x37) Re-initialization of all systems. The camera returns to its initial state, except for all parameters previously stored in EEPROM using SET CAMERA PARAM, that will be retained and will be loaded back at the end of this system reset. If parameter is 0x00, only the image sensor will be reset. The changes will not be written to non-volatile memory and User Custom Parameters will NOT be modified by this command. CAMERA START (0x38) Starts or stops image acquisition and image transmission. After a stop command (CAMERA START with parameter 0x00), the engine begins the procedure for stopping the image sensor. During this time (at max one frame of 16.6ms) the system will not compute any I2C command. GET CAMERA PARAM (0x40) Reads camera system factory parameters or user custom parameters stored in non-volatile memory. Details can be found in Table 6 on page 23, and Table 7 on page 24. GET SENSOR REGISTER (0x31) Returns the desired register value of the Aptina MT9V024 image sensor. Further details on the sensor can be found in the MT9V024 manual. Integration Guide 31 I2C Command Specifications ILLUMINATION DELAY (0x34) Sets the illumination delay time taking as a starting point Sensor Exposure start. Accepts values from 0x00 to 0xFF with a time unit of 30us. ILLUMINATION ENABLE (0x39) With the value set to 0x01 the illumination LEDs will turn on whenever the camera is acquiring images. Setting the value to 0x00 will always turn it off. ILLUMINATION TIME (0x48) Sets the illumination light duration within each frame, with a 50us time increment. Values are from 0x00 (0us) to 0x14 (1ms). RESTORE FACTORY DEFAULT (0x23) The following User Custom Parameters values are restored to their Factory Default:
ILLUMINATION PULSE DURATION ILLUMINATION DELAY AIM PULSE DURATION AIM DELAY SENSOR AEC MAX EXPOSURE See Table 7 on page 24 for Factory Default values. RUN CMD LIST (0x47) Executes the sequence of commands previously memorized using the SET CMD LIST command. SET AUTO POWER TIME (0x45) Sets the timeout value after which power saving mode is activated. When camera is idle and AUTO LOW POWER is active the timer starts counting; whenever any command is issued the timer resets. SENSOR BINNING (0x3C) Modifies sensor register values for image binning:
merging of adjacent pixels with a consequent change of resolution and variation in output image signals timing. A bin of x means that x adjacent pixels are merged
(column or row wise), which means that resolution is
(current resolution)/x (on columns for Column Binning or rows for Row Binning). Column Binning also divides pixel clock frequency by x; row binning also multiplies by x the camera FPS. Binning is applied to the context A or B, depending on the current active CAMERA MODE (see command). 32 DE2011-DL I2C Command Specifications SENSOR BINNING (continued) The parameter to be sent can be calculated by summing the number corresponding to the desired Row Binning, with the number corresponding to the desired Column Binning, as in the following table:
Row Binning codes:
0x00 = No Row Bin 0x01 = Row Bin 2 0x02 = Row Bin 4 Column Binning codes:
0x00 = No Column Bin 0x04 = Column Bin 2 0x08 = Column Bin 4 Total Image Binning code = (Row Binning code) +
(Column Binning code). A value of 0 disables Binning. SET CAMERA PARAM (0x41) Writes the chosen parameter to the cameras non-volatile memory area User Custom Parameters. The stored values will be used as new defaults, replacing the Factory Default Values. For example, after a camera reset or startup the user custom values will be applied. The customizable parameters are:
ILLUMINATION PULSE DURATION ILLUMINATION DELAY AIM PULSE DURATION AIM DELAY SENSOR AEC MAX EXPOSURE See Table 7 on page 24 for details. To roll back the memory to factory default (losing the custom values), use RESTORE FACTORY DEFAULT command. SET COMMAND LIST (0x46) Sets a user-defined sequence of commands to be executed using RUN CMD LIST. Up to ten lists (0 to 9) can be saved; each can store up to 150 bytes (command codes + command parameters). NAK response is issued by the camera if limits are not respected. Possible commands for the list are:
AIM TOGGLE CAMERA START ILLUMINATION ENABLE SET SENSOR REG Command format:
(0x46)(List#)(Total Length) + (Command1 Length)
(Command1) +[]+(Command n Length) (Command n)
+(Checksum) Where command x is the normal byte sequence of the desired command. Integration Guide 33 I2C Command Specifications SET LOW POWER (0x3F) Activates system power saving mode. This command can only be used when the camera is stopped (no image acquisition is in progress), since it puts both the microcontroller and the image sensor into sleep mode. The system wakes up and returns to normal power mode each time a command is issued. SET SENSOR REG (0x30) Stores the new chosen value for the desired register of the Aptina MT9V024 image sensor. Further details on the sensor can be found on the MT9V024 manual. Unpredictable camera behavior may occur. CAUTION Modifying registers manually bypasses the engine system control over the sensor. This could cause the image sensor to behave in a way that conflicts with the engine system working setup and normal operation. 34 DE2011-DL Appendix C Engine Video Format This appendix describes details related to the video port of the engine, the image format and the related timing. Sensor Data Format The Datalogic DE2011-DL engine is based on the WVGA monochrome image sensor. Figure 12 and Figure 13 below show the pixel array description and the spa-
tial illustration of image readout. Figure 12. Pixel array description Figure 13.
