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 engine’s performance.

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.

Figure 6. Exit window positioning – perpendicular window
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.

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)
• three dedicated power supplies (for sensor, digital system, illumination
system)
•an I
2C communication port for controlling the scan engine
Table 3 below describes the power lines and the signals mapped on the 21-
pole ZIF connector.

Connector and Flat cable
The DE2011-DL scan engine is equipped with a Kyocera 21-pole ZIF con-
nector having a pitch of 0.3mm – series 6283 - ordering code 04 6283 021
002 868.
For further details and requirements related to the flat cable, please refer to
the manufacturer’s datasheet, available athttp://www.kyocera‐connec‐
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
at 2.1V.
• 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.

The image sensor power supply, from which the analog
power supply is also generated. 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
VDD 3.3V ± 0.3 The digital and laser aiming system power supply.
VDD_ILLUM_SYS 3.0V to 5.0V The LED illumination system power supply.
I/O level 3.3V 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).

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

DE2011-DL
I2C Command Specifications
This 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.

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.
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 Specifications
32
DE2011-DL
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).
I2C Command Specifications
Integration Guide
33
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 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 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.
I2C Command Specifications
34
DE2011-DL
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.
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.
CAUTION
Unpredictable camera behavior may occur.
