Integration Guide 7Chapter 2Installation This section describes how to design the mounting for optimum scan engine performance.Mounting the Scan EngineGeneral ConsiderationsA 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 engine’s performance.Mechanical SizeFigure 4Nominal size: 21.0mm (width) x 11.4mm (height) x 15.75mm (depth)Maximum size: 21.15mm (width) x 11.55mm (height) x 15.91mm (depth). Nominal Engine Size

Installation8DE2011-DLMounting HolesThere 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 requirementsHousing DesignThe 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 windowThere 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.

Mounting the Scan EngineIntegration Guide 9Figure 6. Exit window positioning – perpendicular windowFigure 7. Exit window positioning – tilted windowAvoiding scratched windowsScratches 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 materialThe 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 13Chapter 3Electrical IntegrationElectrical ConnectionsGroundingThe 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.ESDThe 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)• three dedicated power supplies (for sensor, digital system, illumination system)•an I2C communication port for controlling the scan engineTable 3 below describes the power lines and the signals mapped on the 21-pole ZIF connector.

Integration Guide 17Chapter 4Software Interface Communication ProtocolThe 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 FormatCommands 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 DescriptionStart bit:Start bit as I2C standard specification.Address: Target slave address includes device address plus write option (0x00).For the engine, slave address is 0x5C (or 0xB8 after shifting to 7bit MSB). Command:See list of possible command codes for DE2011 in I2C Com-mand Codes, starting on page 19 or Table 5 on page 19.

Software Interface18DE2011-DLEngine Response FormatWhen the host requests a response from the engine, the response format will be:Same as for sent Command Format, plus:Target slave address includes device address plus read option (0x01).For the engine, slave address is 0x5C (or 0xB8 after shifting to 7bit MSB). STATUS can be one of the following:- ACK (0x80)- NAK (0x82)- CHECKSUM ERROR (0x84)Data returned by the issued command (can be one or multiple bytes or none), LSB first. See Table 5 on page 19.Command Parameters: Data bytes required by the command, shown in Table 5 on page 19. Checksum:1 byte for data integrity check. Checksum is calculated by:• Summing all command bytes, including command code and following data.• Performing 2's complement of the resulting least significant byte (LSB).Stop bit:Stop bit as I2C standard specification.Start bit Address Command (hex code)STATUS Response Data…Stop bit I2C Element DescriptionAddress: STATUS:Response Data: I2C Element Description

I2C Command Specifications30DE2011-DLI2C Command SpecificationsThis section contains a complete description of the DE2011-DL possible I2C supported commands in alphabetical order. 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)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: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.

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.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.The changes will not be written to non-volatile memory and User Custom Parameters will NOT be modified by this command.

I2C Command Specifications32DE2011-DLILLUMINATION 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 EXPOSURESee 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).

I2C Command SpecificationsIntegration Guide 33SENSOR 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 Bin0x01 = Row Bin 20x02 = Row Bin 4Column Binning codes:0x00 = No Column Bin0x04 = Column Bin 20x08 = Column Bin 4Total 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 camera’s 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 DURATIONILLUMINATION DELAYAIM PULSE DURATIONAIM DELAYSENSOR AEC MAX EXPOSURESee 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 STARTILLUMINATION ENABLESET SENSOR REGCommand 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.

I2C Command Specifications34DE2011-DLSET 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.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. CAUTIONUnpredictable camera behavior may occur.
