Position Imager and Symbol
Step 3 — Position Imager and Symbol
• Position the imager at a focal distance between 2 and 6 inches from the symbol.
• Tip the imager relative to the symbol to avoid the glare of direct (specular) reflection. The
case parting line should be perpendicular to the plane of the symbol by either pitching the
symbol or the imager as shown.
• Position the imager in a place with as little ambient light as possible.
• Symbols can be rotated (tilted) at any angle; however, for best results symbols should
be aligned with the FOV (field of view).
Imager and Symbol Orientation
• In the case of linear symbols, aligning the bars in the direction of their movement (“ladder”
orientation) will minimize the chances of blurring, and will produce better reads.
Important: Avoid excessive skew or pitch. Maximum skew is ±30°; maximum pitch is
±30°. The illustration below shows skew axis, pitch axis, and tilt axis.

Step 8 — Calibrate
MINI Hawk settings can be adjusted automatically for optimum symbol decoding performance
by either the EZ Button or by ESP.
During the calibration routine, the reader will flash its amber Read Rate percent LEDs and
red illumination LEDs while searching camera settings and determining the best configuration
for decoding symbol data. Upon successful completion of this routine, a green LED pattern
will flash brightly and illuminate the symbol. If unsuccessful, the imager will emit 5 short beeps

This section is designed to help you understand the basic structure and elements of ESP
(Easy Setup Program).
When you open ESP, unless otherwise specified in the ESP Preferences dialog accessible
from the Options heading on the menu toolbar, you will enter EZ Mode for initial setup.
From there, you can enter Application Mode (App Mode) and access several configuration
menus (Communications, Read Cycle, Symbologies, I/O Parameters, Symbol Quality,
Matchcode, and Diagnostics), a Camera setup interface, a Terminal interface, a Utilities
interface, and an Output Format interface.
ESP can be used to configure the MINI Hawk in three different ways:
• Tree Controls: Each configuration menu contains a list of all option settings that pertain to that
specific element of imager operation. For example, the Communications menu shows a
Host Port Connections option, and then a list of the sub-options Baud Rate, Parity, Stop
Bits, and Data Bits. Each of these sub-options is configurable by using dropdown menus.
• Graphic User Interfaces: Imager settings can be configured using such point-and-click
tools as radio buttons, zoom in/zoom out sliders, spin boxes, check boxes, and drag-and-drop
functions.
• Terminal: ESP’s Terminal allows you to send serial configuration and utility commands
directly to the imager by typing them in the provided text field.
Information about using ESP in specific applications is provided in subsequent sections.
For ESP system requirements, see Minimum System Requirements in Chapter 1, Quick Start.

MINI Hawk High Performance Imager User Manual
Communications
Host Port Protocol
Usage:
In general, the point-to-point protocols will work well in most applications.
They require no address and must use RS-232 or RS-422 communications
standards.
Definition:
Protocols define the sequence and format in which information is transferred
between the reader and the host, or in the case of Multidrop, between the
readers and a concentrator.
Serial Cmd:
Default:
Point-to-Point
Options:
0 = Point-to-Point
1 = Point-to-Point with RTS/CTS
2 = Point-to-Point with XON/XOFF
3 = Point-to-Point with RTS/CTS and XON/XOFF
4 = ACK/NAK
5 = Polling Mode
Note: In all protocol modes, the preamble and postamble character
strings can be used to frame the decode data, and both are included in calculating the
LRC (Longitudinal Redundancy Check).
Point-to-Point (Standard)
Usage:
Definition:
Serial Cmd:
Used only with RS-232 or RS-422.
Standard Point-to-Point requires no address and sends the data to the
host whenever it is available, without a request or handshake from the host.
Point-to-Point with RTS/CTS
Usage:
Definition:
Serial Cmd:
A reader initiates a data transfer with an RTS (request-to-send) transmission.
The host, when ready, responds with a CTS (clear-to-send) and the data is
transmitted. RTS and CTS signals are transmitted over two dedicated wires
as defined in the RS-232 standard. Used only with RS-232.
Point-to-Point with RTS/CTS (request-to-send/clear-to-send) is a simple
hardware handshake protocol that allows a reader to initiate data transfers
to the host.
Point-to-Point with XON/XOFF
Usage:
Definition:
Serial Cmd:
If an XOFF has been received from the host, data will not be sent to the host
until the host sends an XON. During the XOFF phase, the host is free to carry
on other chores and accept data from other devices. Used only with RS-232.
This option enables the host to send the XON and XOFF command as a
single byte transmission command of start (^Q) or stop (^S).

Host Port Protocol
Point-to-Point with RTS/CTS and XON/XOFF
Usage:
Definition:
Serial Cmd:
Used only with RS-232.
This option is a combination of Point-to-Point with RTS/CTS and Pointto-Point with XON/XOFF.

ACK/NAK Options
Definition:
Serial Cmd:
These parameters take effect for ACK/NAK on the main RS-232 or
RS-422 ports (not on the Auxiliary Port), and are completely independent of
the Polling Mode Options .
The imager always follows the protocol in both directions (to and from the
host). There is no option to disable it from either direction.
RES-NAK Defaults
RES: (Reset)
REQ: (Request)
STX: (Start of Text)
ETX: (End of Text)
ACK: (Acknowledge)
NAK: (Negative Acknowledge)
00 (disabled)
00 (disabled)
00 (disabled)
00 (disabled)
06
15
The following are general outlines of the ACK/NAK protocol. Items that are framed by
brackets ( [ ] ) can either be disabled or enabled. LRC does not include STX, but it does
include preamble, postamble, and ETX.
Symbol Data Output
TX to host: [STX] [preamble] SYMBOL DATA [postamble] [ETX] [LRC]
Response from host: ACK/NAK. Sent when LRC, ETX, postamble, or timeout (waiting
for more data) are detected (if REQ is disabled) depending on what is enabled.
Commands from Host to Imager
TX to Imager: [STX] [ETX] [LRC]
Response from Imager: ACK/NAK. Sent when LRC, ETX, or command-ending angle
bracket ‘>’ are received, depending on what is enabled.
Command Response from Imager to Host
TX to host: [STX] [preamble] COMMAND RESPONSE DATA [postamble] [ETX] [LRC]
Response from host: ACK/NAK. Sent when LRC, ETX, postamble, command-ending
angle bracket ‘>’, or timeout (waiting for more data) are detected, depending on what is
enabled.
As with Polling Mode , the imager can optionally perform the REQ and RES
event sequences in ACK/NAK mode. If the sender does not receive an ACK or NAK, it will
send REQ to request such a response (if enabled). When the sender receives an ACK, too
many NAKs, or times out (if already enabled), it will send a RES (if enabled) to terminate the
transaction.
Note: See ACK/NAK Data Flow Examples in Appendix D for sample ACK/NAK communication
scenarios.
Note: See USB HID Interface on page 3-23 for protocol information relating to USB.

The auxiliary port offers an alternative port that can be configured to communicate by
RS-232 in several modes, including daisy chain.
As with the host port parameters, the auxiliary port settings (baud rate, parity, stop bits,
and data bits) must be identical with those of the auxiliary device.
Usage:
Definition:
An auxiliary port connects the imager to a remote display or to other readers

A common application, in conjunction with handheld imagers, is one that
employs an auxiliary readout to detect misapplied symbols.
In Transparent Mode, data is passed between the auxiliary port and the
host. The imager buffers data from the auxiliary port and echoes the keyed
data on the auxiliary port.
• Auxiliary port data is passed through to the
host whenever a return key is pressed at the
auxiliary port or whenever symbol data is
sent. If sent with symbol data, it is processed
on a first-in/first-out basis.
• Auxiliary port data to the host is always sent
with a preamble and postamble.
• If the imager is in a polling mode with the
host, auxiliary port data will still pass
through.

Daisy Chain Mode
Usage:
Definition:
Serial Cmd:
Options:
Function:
Useful in applications where:
• More than one symbol type is present.
• A symbol may be present on multiple sides of a package.
• Symbols are presented at different depths.
In a daisy chain application, readers are connected in tandem or a “daisy
chain” and decoded data is relayed from one reader to another until the
data reaches the host.
A primary reader has its host port linked to the host computer and its auxiliary
port linked to the host port of the first secondary reader in the chain.
Thereafter, each secondary reader’s auxiliary port is linked to the host port
of the secondary reader that is farther from the host in the daisy chain.
Each reader in the chain can be assigned an ID that accompanies any data
that it sends.
4 = Daisy Chain
Before the primary reader times out, it checks its auxiliary port for data. It
should be set to wait at least 30 ms for each secondary reader in the daisy
chain. If no data is received within the read cycle timeout, the primary
reader sends a No Read message to the host. Otherwise the complete data
is sent.
If, for example, the primary reader is set to timeout in 120 ms, the first
secondary reader reader downstream might be set to 90 ms, the next to 30
ms, and so forth, thus assuring that at least 30 ms elapses between transmissions.a
Daisy-chained readers can send a series of symbols by enabling Multisymbol
and a common multisymbol separator. If the primary reader does not
receive the expected number of symbols, No Read messages are
appended to the data string to make up the difference between the number
of symbols enabled in Multisymbol and the number of symbols read.
For example, a primary and two secondary readers have Number of
Symbols set to 3 and Multisymbol Separator defined as %. If the primary
and the first secondary reader do not find symbols, but the next secondary
reader registers a good read, the transmitted results would be:
symbol data % No Read % No Read
a. The above example assumes a best-case scenario. Other factors, such as baud rate, dynamic focus
timing, number of characters in a given symbol, and the number of secondary readers in the daisy chain
can affect timing and may need to be included in your calculations for complete accuracy.

Daisy Chain Autoconfigure
Usage:
Definition:
Serial Cmd:
For quick setup and configuration of your daisy chain network.
The command to autoconfigure the daisy chain is sent to the primary
imager and the software responds in the following ways:
• Counts the number of secondary readers in the daisy chain.
• Assigns an internal ID number (1...n) to each secondary reader, where
the first secondary reader is number 1 (the primary reader’s ID being a 0).
• Propagates the communications settings and the relevant operating
modes of the primary imager to the host and auxiliary ports of each
secondary reader.
• Resets each secondary reader.
• Confirms that each secondary reader has acquired the new settings.
Note: All secondary readers must be set to Serial for Daisy Chain to function.
When setting up a daisy chain operation, perform the following steps:
1. Set the primary imager (the one connected to the host) to Serial.
This sets all the imagers in the chain to Serial when the command is executed.
Before Autoconfigure you must set the primary imager to Serial (S):

USB HID Interface
The USB version of the MINI Hawk operates as an HID (Human Interface Device) on the
USB bus. HID-class devices communicate via “report” packets. An HID may support
multiple report types, each of which is identified with a unique report ID. The MINI Hawk
supports two different report types:
• Omron Microscan HID Report (ID = 1)
• Keyboard Report (ID = 2)
The imager always outputs the same data for both report types. The user may enable or
disable either report type.
Regardless of the report type used by the host application, the application protocol via USB
is identical to RS-232/RS-422 ports. HID Reports are used as a channel for standard
Omron Microscan imager communication, command input, and symbol data output.
Important: No matter how the imager is configured, it is always able to receive and
respond to commands from the host application using Omron Microscan HID Reports.
MINI Hawk High Performance Imager User Manual

USB HID Interface
Report Options
The following functionality conditions hold true regardless of how HID Reports are configured:
1. The host application must establish a connection with the imager to receive Omron Microscan
HID IN Reports (symbol data) and to send Omron Microscan HID OUT Reports (commands,
serial triggers).
2. The imager can always receive Omron Microscan HID OUT Reports (commands, serial triggers).
3. The host application can always send commands through Omron Microscan HID OUT
Reports. If the command requires a response (a part number, for example), the imager will
always send the response through Omron Microscan HID IN Reports.
4. The imager always ignores Keyboard OUT Reports sent by the host operating system.
5. The content of both the Keyboard Reports and Omron Microscan HID IN Reports is
identical, except for Keyboard Reports non-printable data limitations.
Omron Microscan HID IN Reports
HID Reports are used as a channel for standard Omron Microscan imager
communication, command input, and symbol data output. There are two types of
Omron Microscan HID Reports:
Report Type
HID IN (imager to host)
HID OUT (host to imager)
Data Content
Symbol data; No Reads; Service messages
Commands; serial triggers
Note: The imager is always able to receive commands and serial triggers from the host
through HID OUT Reports, regardless of the HID IN Report status. If the imager receives a
command that requests a response, such as a part number query, the imager will send a HID
IN Report regardless of the IN Report status.

Keyboard Reports protocol requires that two reports be sent for every keystroke. The first
report indicates which key is pressed. The second report indicates “no key pressed”, with
all keycodes NUL (0x00) to indicate that all keys have been released. In the case of the

USB HID Interface
USB HID Configuration Options
The user has the following options for configuring and defaulting a USB version of the
MINI Hawk:
Configuration Symbols (Data Matrix with “Configure Reader” Flag)
Symbol configuration can be performed “out-of-the-box”, as the MINI Hawk is configured for
Continuous Read Mode, and Data Matrix is enabled by default. Data Matrix symbols are
used to encode configuration commands when the symbology’s “configure reader” flag is set.
If the read cycle is changed, or if Data Matrix is disabled, another configuration/default
method must be used. This is because the USB MINI Hawk has no external trigger, unless
the user has configured the EZ button as a trigger.
EZ Button Configuration
By default, basic calibration can be initiated from the EZ button (3 beeps). Note that this
only changes the camera, image processing, and symbology settings of the imager. To
default the USB MINI Hawk, hold down the EZ button during power-on.
Note: This only overwrites Power-On settings with Custom Default settings, as when the
command is received. It does not overwrite Power-On settings with Factory
Defaults, as when the command is received. If Custom Defaults are misconfigured,
another method must be used to default the imager.
Implementing the Host Operating System API and Establishing a
Connection with the Omron Microscan HID Interface
When a connection is made, the host can send serial configuration/default commands. The
imager will always be able to receive configuration commands from the host application and
send responses to those commands. However, the imager can be configured to stop producing
IN Reports to the host from symbol data output and diagnostics (service messages).

Configuration Exceptions for USB
Read Cycle Mode
By default, the imager operates in Continuous Read Mode. If the imager is configured
using Data Matrix symbols, the read cycle mode should be the last item changed before
saving the configuration settings and beginning operation. This is because all read cycle
modes other than Continuous Read Mode require a trigger event. In USB, a trigger event
can only be initiated by serial command. To send a trigger command the imager, the host
application must establish a connection with the imager’s Omron Microscan HID
interface and send the trigger command in an Omron Microscan HID Report.
The following read cycle conditions are required for USB MINI Hawk:
Serial Cmd:
Default:
Options:
Continuous
0 = Continuous Mode 1 = Coninuous Read 1 Output Mode
2 = Level Mode
3 = Edge Mode

• To use Serial Mode, you must use the Delimited Trigger defined by , or enable
and use the Undelimited Start Trigger Character .
• To use Serial and Edge Mode, you must use the Delimited Trigger defined by
, or enable and use the Undelimited Start Trigger Character .
Communications
For the USB version of MINI Hawk, no communications serial commands have any effect
on the imager except the following:
• USB HID Report Status
• Preamble
• Postamble
EZ Button
Default on power-on cannot be disabled = . This ensures a
level of safety for recovering from misconfigured Power-On settings . However, it is not
foolproof, as defaulting with the EZ button only recovers Custom Default settings, which
can be misconfigured themselves. For this reason, do not save to Custom Default settings
until the imager’s configuration has been tested.
Symbologies
If the imager is going to be configured with Data Matrix symbols, do not disable Data Matrix
. Disabling Data Matrix will prevent the imager from reading configuration symbols.

can be sent to the imager as hex pairs (see Appendix E, ASCII Table, for conversions).
Serial Cmd Format:
To enter ASCII fields as hex values (00 to FF), add a lower-case h directly after the command’s
K number, and then enter the hex value that corresponds with the desired ASCII character.
Example:
Consider the Postamble command:
Serial Cmd:
Imagine that your application requires the ASCII character > to be the postamble in your
symbol decode output.
The ASCII characters , and , can only be entered as hex pairs. So, to make > the
postamble in your symbol decode output, enter the Postamble command as follows:
Note that the “status” field contains only a , . This is because the only field that is being
changed is the “postamble character(s)” field. (See Serial Configuration Command
Conventions on page A-14 for a more detailed explanation of this command shortcut.)

Autocalibrate
Calibration Overview
Autocalibration is one of the most powerful features of the MINI Hawk. The calibration
process can be initiated by serial command, EZ button, or ESP user interface.
When the imager enters calibration, it runs through an optimization cycle that sets the ideal
parameters for reading symbols at the highest possible level of performance. Autocalibration
can be specially configured to optimize specific parameters, such as focus, gain, shutter
speed, and symbol type.
The calibration process consists of five separate phases: quick focus, search pass, focus
pass, medium pass, and fine-tune pass. During this process the imager quickly locates
configuration setup, defines a calibration range for the configuration parameters, and then
tunes those parameters for optimal performance.

Calibration
Calibration Options
This command specifies the operation of the imager’s calibration feature. The default
configuration is set up to perform calibration on gain, focus, and symbol type. The
default shutter speed setting is disabled, because not all applications require shutter
speed, and when it is required, the application-specific settings tend to vary widely.
Note: Background Color is part of the calibration process regardless of the calibration
setup. After successful completion of the calibration routine, the background color will be
set to the appropriate value, depending on the symbol in the field of view. The Illumination
Brightness parameter is not part of the calibration process, and it must be configured
appropriately prior to calibration.
Gain
Definition:
Serial Cmd:
Default:
Options:
When enabled, gain will be calibrated to provide the best available image
quality and performance.
When disabled, gain is fixed and is not part of the calibration process.
Enabled
0 = Disabled
1 = Enabled
Shutter Speed
Unless an application is a static setup, the shutter speed setting should be
configured by the user based on the application. For dynamic applications, the
user should configure the shutter speed setting so the calibration process can
optimize the gain for that setting.

Note: The following table shows general guidelines for shutter speed configurations based on
various line speeds. The configurations shown depend on the imager’s optical configuration,
and on symbol element size.

Disabled (Shutter Speed)
When this feature is disabled, the shutter speed is fixed and is not part of the calibration
process.
Enabled (Shutter Speed)
When this feature is enabled, shutter speed will be calibrated to provide the best possible
image quality and performance.
Fast Shutter
The calibration process will concentrate on achieving the fastest possible shutter setting that
will still provide good performance. The image quality or contrast may not be as good as
what would be achieved with the Enabled setting. The calibration process is not designed to
choose the fastest shutter speed that can decode a symbol, but rather to optimize for the
fastest shutter speed that still provides good image quality.

Calibration
Focus Position
Definition:
Serial Cmd:
Default:
Options:
Since focus can be configured by entering the target distance from the
imager’s parting line, the user will normally configure the focus setting
without needing to calibrate. However, if it is necessary to calibrate the
focus distance, there are two methods for doing so: the standard “Search
Method”, or a “Quick Focus” method, both of which are defined below.
Quick Focus
0 = Disabled
1 = Enabled
2 = Quick Focus
Disabled
When this feature is disabled, the focus position is fixed and is not part of the calibration
process.
Enabled (Search Method)
When this feature is enabled, the focus position will be calibrated to provide the best possible
image quality and performance. This method is essentially a search method that attempts to
identify the desired focus using a search algorithm that cycles through focus settings to try
and locate the desired focus as quickly as possible. This is accomplished when the given
symbol in the field of view is decoded. Once a focus distance that will decode the given
symbol has been located, the search algorithm will fine-tune the search to locate the
“inside” and “outside” focal distances. The final focus distance will be between the “inside”
and “outside” values.
Note: This method can be time-consuming if the focus is not found on the first pass.
Quick Focus
Quick Focus is designed to quickly locate the focus setting for an object in the field of view.
This is accomplished with minimal processing of the image by analyzing a histogram of
the image frame. Before performing the focus calibration, a value for shutter speed and
gain is determined and then the calibration process will step through the focus range of the
system, capturing the required number of image frames for each focal position. A histogram
is performed on each image frame and the histogram results for each focus position are
averaged. When this process is completed, the data is analyzed and the optimal focus position
is determined.
Note: Quick Focus may not work well for all applications. It is not recommended for
applications that use very small symbols.

Disabled
When this feature is disabled, only the currently-enabled symbologies will be considered
during the calibration process.
Enabled
When this feature is enabled, autodiscrimination will be in effect during the calibration
process. All symbologies that are readable by the imager except PDF417 and Pharmacode
will be considered during calibration. Any new symbologies successfully decoded during
calibration will remain enabled at the end of the process. All enabled symbologies will
remain enabled.
For example, assume that only Code 39 is enabled at the beginning of calibration. If a
Code 128 symbol is read during calibration, then Code 128, as well as Code 39, will be
enabled after the calibration process is complete.

Window of Interest (WOI) Framing
Definition:
Serial Cmd:
Default:
Options:
Configured WOI
If a WOI framing mode is enabled, it will set the camera WOI to a full-size
image when calibration begins. Once a symbol is decoded, the camera
WOI will be zoomed-in both vertically and horizontally (regardless of
which WOI mode is enabled) to include the symbol plus an additional
margin area. This is done to accelerate the calibration process.
When a successful calibration process is completed, the camera WOI
will be adjusted according to the mode enabled. Otherwise, the original
WOI configuration will be retained.

Straight Line
This feature is intended for use with linear symbologies. If the calibration process is successful,
the orientation of the symbol is determined and the Window of Interest is modified according
to the symbol orientation. The scan line orientation is determined to be vertical if the
symbol tilt is between 225° and 315°, or between 45° and 135°. Otherwise, the scan line
will be horizontal.
If the symbol is vertical, the image column size will be set by the scan height parameter,
and will be configured for full row resolution. If the symbol is horizontal, the image row size
will be set by the scan height parameter, and will be configured for full column resolution.
The scan line will be centered in the middle of the symbol. If the symbol is tilted such that
the scan line will not pass completely through the symbol, the scan width will be adjusted
to include the entire symbol. Refer to the diagram below:
Straight Line Framed
This parameter is the same as “Straight Line”, except that the Window of Interest will also
frame the scan line on the symbol length as well. The scan line includes the symbol plus
an additional margin area determined by the WOI Margin parameter.

Calibration
Additional Notes about Calibration
The following conditions apply to the imager’s calibration process. Some of these items
are noted at various points throughout this section, or in other sections of the imager’s
documentation.
1. The Illumination Brightness parameter is not part of the calibration process.
2. Background Color is calibrated.
3. If Window of Interest Framing is enabled, the WOI will be set to full frame when
calibration begins. If WOI Framing is disabled, the current WOI configuration will be
used for the Search Pass.
4. If Symbol Type is enabled for calibration (Autodiscriminate), then Interleaved 2 of 5
Range Mode Status (Interleaved 2 of 5) will be enabled. This allows variable-length
Interleaved 2 of 5 symbols to be decoded. If an Interleaved 2 of 5 symbol is decoded
during calibration, then code length # 1 will be set to the decoded symbol length at the
end of calibration. Otherwise, the symbol lengths will be restored to their original
configurations.
5. Pharmacode is not calibrated.
6. All symbol types that were enabled before calibration will still be enabled after calibration.
For example, if Data Matrix ECC 200 was enabled before calibration, and the calibration
routine was performed on a Code 128 symbol, then after calibration is completed both
Data Matrix ECC 200 and Code 128 will be enabled.
7. The calibration process does not modify the global Composite status . The
global Composite status must be configured properly before calibration.
8. If the user requires calibration of a stacked symbology , , or ,
that symbology must be enabled and configured appropriately before calibration.
9. UPC Supplementals will be disabled during calibration.
10. The Search process will use the configurable Window of Interest for image captures.
However, when the search process is completed, the WOI will be reduced to include
only the symbol of interest and some additional boundary area.

Read Cycle Setup
Read Cycle Setup
Setting up read cycle and triggering parameters will involve a series of decisions based on
your particular application, as follows:
1. Select the number of symbols to be read in a single cycle. The MINI Hawk can read
multiple symbols in a single image frame.
2. Decide on the trigger type to be used: if serial, choose a serial character; if external,
choose either Level or Edge.
3. Designate how the read cycle should end (Timeout, New Trigger, Last Frame).
4. Select Capture Mode, Continuous Mode, or Rapid Mode.
5. Select Number of Captures (if in Rapid Capture Mode).
6. Set the Time Before First Capture and Time Between Captures, if any.
Note: The imager’s camera captures images at a rate of about 16/second (based on a
1280 x 1024 image). The capture rate increases as frame sizes decrease.
Note: If you need to set up your MINI Hawk for use with EZ Trax software, see Setting Up
the Imager for EZ Trax.

Read Cycle
Multisymbol
Usage:
Definition:
Conditions:
Multisymbol is commonly used in shipping applications where a shipping
symbol contains individual symbols for part number, quantity, etc. This
feature allows on trigger to pick up all the symbols.
Multisymbol allows the user to define up to 100 symbols that can be read
in a single read cycle.
The following conditions apply:
• Each symbol must be different to be read, unless in Rapid Capture
Mode, configured for “triggered capture”.
• The maximum number of characters in a read cycle is 3,000 for all
symbols.
• All No Read messages are posted at the end of the data string, unless
output filtering is enabled.
• If more than one symbol is within the field of view at the same time,
symbol data may not be displayed in the order of appearance.
• If Matchcode Type is set to Sequential or if Trigger is set to Continuous
Read 1 Output, the imager will behave as if Number of Symbols were
set to 1, regardless of the user-defined configuration.

Continuous Read
Usage:
Definition:
Serial Cmd:
5-6
Continuous Read is useful in testing symbol readability or reader functions.
It is not recommended for normal operations.
In Continuous Read, trigger input options are disabled, the imager is
always in the read cycle, and it will attempt to decode and transmit every
capture. If a single symbol stays within read range for multiple read cycles,
its data will be transmitted repeatedly until it leaves the read range.
The imager sends replies to serial commands that require responses when
symbol data is transmitted, or read cycle timeout is enabled and a timeout
occurs and at least one captured image has been processed. Depending
on the combination of enabled symbologies, the imager may take longer
than the timeout to process a captured image.
Note: When to Output and No Read options have no affect on Continuous
Read.
MINI Hawk High Performance Imager User Manual
Read Cycle
Continuous Read 1 Output
Usage:
Definition:
Serial Cmd:
Continuous Read 1 Output can be useful in applications where it is not
feasible to use a trigger and all succeeding symbols contain different
information. It is also effective in applications where the objects are presented
by hand.
In Continuous Read 1 Output the imager self-triggers whenever it
decodes a new symbol or a timeout occurs.
If End of Read Cycle is set to Timeout and the symbol doesn’t change,
the output is repeated at the end of each timeout period. For example, if
Timeout is set to one second, the imager sends the symbol data immediately
and repeats the output at intervals of one second for as long as it continues
to capture the symbol.
If End of Read Cycle is set to New Trigger, the imager will send the current
symbol data immediately, but only once. A new symbol appearing in the
imager’s range will be read and sent immediately, provided it is not identical
to the previous symbol.
Caution: In automated environments, Continuous Read 1 Output is not recommended
because there is typically no reliable way to verify that a symbol was missed.
Note: If Trigger Mode is set to Continuous Read 1 Output, the imager will behave as if
Number of Symbols were set to 1, regardless of the user-defined configuration.

Trigger Mode and Filter Duration
External Level
Initiate Read Cycle:
Object #1, moving in front of the
detector beam, causes a
change in the trigger state,
which initiates the read cycle.
End Read Cycle:
The same object, moving out of
the detector beam, causes
another change in the trigger
state, which ends the read cycle.
Usage:
Definition:
Serial Cmd:
This mode is effective in an application where the speeds of the conveying
apparatus are variable and the time the imager spends reading each object
is not predictable. It also allows the user to determine if a No Read has
occurred.
External Level allows the read cycle (active state) to begin when a trigger
(change of state) from an external sensing device is received. The read
cycle persists until the object moves out of the sensor range and the active
trigger state changes again.
Important: Level and Edge apply to the active logic state (Negative or Positive) that exists
while the object is in a read cycle, between the rising edge and the falling edge. Rising edge
is the trigger signal associated with the appearance of an object. Falling edge is the trigger
signal associated with the subsequent disappearance of the object. This applies both to
External Level and External Edge.
External Edge
Initiate Read Cycle:
Object # 1, moving in front of the
detector beam, causes a change in
the trigger state, which initiates the
read cycle.
Initiate Second Read Cycle:
Object # 2, moving in front of the
detector beam, causes another
change in the trigger state. This signal initiates a new read cycle and
ends the previous read cycle unless
Timeout is enabled and a good read
or timeout has not occured.
Usage:
Definition:
Serial Cmd:
5-8
This mode is highly recommended in any application where conveying
speed is constant, or if spacing, object size, or read cycle timeouts are
consistent.
External Edge, as with Level, allows the read cycle (active state) to begin
when a trigger (change of state) from an external sensing device is
received. However, the passing of an object out of sensor range does not
end the read cycle. The read cycle ends with a good read output, or,
depending on the End of Read Cycle setting, a timeout or new trigger
occurs.
MINI Hawk High Performance Imager User Manual
Read Cycle
Serial Data
Usage:
Definition:
Serial Cmd:
Serial Data is effective in a highly controlled environment where the host
knows precisely when the object is in the field of view. It is also useful in
determining if a No Read has occurred.
In Serial Data, the imager accepts an ASCII character from the host or
controlling device as a trigger to start a read cycle. A Serial Data trigger
behaves the same as an External Edge trigger.
Serial commands are entered inside angle brackets, as shown here: .
Note: In Serial Data, sending a non-delimited start serial character will start a read cycle;
however, a non-delimited stop serial character has no effect.
Serial Data and Edge
Usage:
Definition:
Serial Cmd:
Serial Data or External Edge is seldom used but can be useful in an
application that primarily uses an external sensing device but occasionally
needs to be triggered manually.
An auxiliary terminal can be connected to the auxiliary port so the user can
send the serial trigger character through the imager to the host.
In this mode the imager accepts either a serial ASCII character or an external
trigger pulse to start the read cycle.
Note: In Serial Data, sending a non-delimited start serial character will start a read cycle;
however, a non-delimited stop serial character has no effect.

Leading Edge Trigger Filter
Usage:
Definition:
Serial Cmd:
Default:
Options:
Used to ignore spurious triggers when Trigger Mode is set to External
Edge or External Level.
To consider a change in state on the trigger input, the level must be stable
for the trigger filter duration. In an edge mode, the imager will trigger a read
cycle if the active state has been uninterrupted for the entire trigger filter
duration. In a level mode, the leading edge is filtered such that on an active
edge, the state must be held interrupted for the trigger filter duration before
a trigger will occur.

Definition:
To consider a change in state on the trigger input, the level must be stable
for the trigger filter duration. In an edge mode, the imager will trigger a read
cycle if the active state has been uninterrupted for the entire trigger filter
duration. In a level mode, the trailing edge is filtered such that on the falling
edge, the state must be held for the trigger filter duration before the trigger
will be deemed inactive.

When defining Start trigger characters, the following rules apply:
• In External Edge the imager looks only for the Start trigger character
and ignores any Stop trigger character that may be defined.
• In External Level the Start trigger character begins the read cycle and
the Stop trigger character ends it. Note that even after a symbol has
been decoded and the symbol data transmitted, the imager remains in
External Level trigger read cycle until a Stop character is received.
• In Serial Data or External Edge trigger mode, either a Start trigger
character or a hardware trigger can start an edge trigger read cycle.

Read Cycle
End of Read Cycle
Definition:
The read cycle is the time during which the imager will attempt to capture
and decode a symbol. A read cycle can be ended by a timeout, a new
trigger, or by the last frame in a capture sequence or a combination of the
above.

Timeout
Usage:
Definition:
Typically used with Serial Data or External Edge and Continuous Read
1 Output.
It is effective in highly controlled applications when the maximum length of
time between objects can be predicted. It assures that a read cycle ends
before the next symbol appears, giving the system extra time to decode
and transmit the data to the host.
Timeout ends the read cycle, causing the reader to stop reading symbols
and send the symbol data or No Read message when the time set in Timeout
elapses (times out), if When to Output is set to End of Read Cycle.
If in Continuous Read 1 Output, a timeout initiates a new read cycle and
allows the same symbol to be read again.
With External Edge, Serial Data, or Serial Data or External Edge
enabled, a timeout ends the read cycle and symbol data or a No Read
message is sent to the host.
With External Level enabled, the read cycle does not end until the falling
edge trigger occurs or a timeout occurs. The next read cycle does not begin
until the next rising edge trigger.
MINI Hawk High Performance Imager User Manual
5-15
End of Read Cycle
New Trigger
Usage:
Definition:
New Trigger is an effective way to end a read cycle when objects move
past the reader at irregular intervals (not timing-dependent).
New Trigger ends the current read cycle and initiates a new one when a
new trigger occurs. New Trigger refers only to a rising edge trigger.
With External Edge, Serial Data, or Serial Data or External Edge
enabled, an edge or serial trigger ends a read cycle and initiates the next
read cycle.
In the case of External Level, a falling edge trigger ends the read cycle but
the next read cycle does not begin until the occurrence of the next rising
edge trigger.
Timeout or New Trigger
Usage:
Definition:
Useful in applications that require an alternative way to end the read
cycle. For example, if an assembly line should stop completely or the
intervals between objects are highly irregular.
Timeout or New Trigger is identical to Timeout except that a timeout or a
new trigger (whichever occurs first) ends the read cycle.
Last Frame
Usage:
Definition:
Useful in applications in which the number of captures needed can be
defined but the timeout duration varies.
Last Frame only applies to Rapid Capture Mode.
Last Frame or New Trigger
Usage:
Definition:
Useful in applications in which line speeds are irregular and a new
labelled object could appear before the last frame in a Rapid Capture
sequence.
Last Frame or New Trigger is identical to New Trigger except that a new
trigger or last frame (whichever occurs first) ends the read cycle.

Rapid Capture
Definition:
In a rapid capture mode, one or multiple captures (as many as 32) can be
taken at an interval specified by the time-between-captures parameter. In
this mode, the only limiting time factor is integration and transfer timing.
Continuous Capture
Usage:
Definition:
Continuous Capture is useful in applications with slower line speeds or
where symbol spacing may be random or not time-dependent.
In Continuous Capture Mode, image captures are taken throughout the
read cycle in a multi-buffered format (see diagram below). The imager
begins processing the first captured image at the same time that it captures
the second image. Captures will continue occurring throughout the read
cycle until an end condition occurs, such as a timeout, a new trigger, the
last frame in a capture sequence, or a combination of the above.

Rapid Capture Mode. This feature is used in conjunction with Capture Timing
parameters to specify the capture sequence of a rapid capture read cycle.
1
1 to 64
Note: The range of maximum number of captures is dynamic. This range is dependent
on the maximum image size in the system. A full-size image (1280 x 1024) reduces the
maximum number of images to 6. The smaller the image size, the greater the maximum
number of captures. Once the image size is reduced to small enough dimensions, the
maximum number of captures will be capped at 64.
If a user enters a maximum capture value greater than that allowed, the value will be
limited to the number of system images. This command also affects the number of
stored images allowed in the system. If the maximum number of captures is selected,
the number of stored images allowed will be 0.

captures.
Also, consecutive captures are regarded as the same symbol if the output
data is the same.

Overview of Matchcode
Overview of Matchcode
Definition:
Usage:
Matchcode allows the user to store master symbol data in the imager’s
memory, compare that data against other symbol data, and define how
symbol data and/or discrete signal output will be directed.
A master symbol database can be set up for up to 10 master symbols.
Note: Matchcode will function with multiple symbols; however, if Matchcode
Type is set to Sequential or if Triggering Mode is set to Continuous Read 1
Output, the imager will behave as if Number of Symbols were set to 1,
regardless of the user-defined configuration.
Matchcode is used in applications to sort, route, or verify data based on
matching the specific symbol in a variety of ways as defined in this section.
For example, a manufacturer might sort a product based on dates that
are embedded in the symbol.
Steps for Entering and Using Master Symbols
1. Set Triggering Mode to External or Serial.
2. Choose the method of symbol comparison that fits your application.
3. Define the output you want to achieve with your matchcode setup:
a. Symbol data output
b. Discrete output
4. Select the number of master symbols you want to create.
5. Decide which of 4 ways you want to enter your master symbol(s):
a. Use ESP to type master symbol data directly.
b. Send a serial command with symbol data in the form of .
c. Send a (Read Next Symbol as Master Symbol) command.
d. Enable the New Master Pin command and activate the discrete input to store the
next symbol read as the master symbol.

compare symbols or portions of symbols for sequential numbers.
Note: If Matchcode Type is set to Sequential, the imager will behave
as if Number of Symbols were set to 1, regardless of the user-defined
configuration.
MINI Hawk High Performance Imager User Manual

Matchcode Type
Sequential Matching
Usage:
Definition:
Serial Cmd:
Default:
Options:
Useful in tracking product serial numbers that increment or decrement
sequentially.
With Sequential enabled, Sequential Matching determines if a count is in
ascending (incremental) or descending (decremental) order.
Increment
0 = Increment
1 = Decrement
Match Start Position
Usage:
Match Start Position is useful in defining specific portions of a symbol
for comparison. For example, if a symbol contains a part number, manufacturing
date, and lot code info, but you are only interested in the part number
information, you can set the imager to sort only the part number and
ignore the other characters.
Definition:
Match Start Position determines the portions of symbols that will be
matched by defining the first character in the symbol (from left to right)
that will be compared with those of the master symbol, when Matchcode
Type is set to Enabled or Sequential.
Function:
For example, if Match Start Position is set to 3, the first 2 characters
read in the symbol will be ignored and only the 3rd and subsequent
characters to the right will be compared, up to the number of characters
specified by Match Length.
Serial Cmd:
Default:
0
Options:
0 to 3000
Note: Match Start Position must be set to 1 or greater to enable this feature. A 0 setting
will disable this feature.
Match Length
Usage:
Definition:
Serial Cmd:
Default:
Options:
9-6
Example: If Match Length is set to 6 in a 10-character symbol, and
Match Start Position is set to 2, only the 2nd through 7th characters
(from left to right) will be compared.
Defines the length of the character string that will be compared with that
of the master symbol when Match Start Position is set to 1 or greater.
When Match Start Position is set to 0, no comparison will occur.
1
1 to 3000
MINI Hawk High Performance Imager User Manual
Matchcode
Wild Card Character
Usage:
Definition:
Serial Cmd:
Default:
Options:
Example: With Wild Card Character defined as the default asterisk,
defining CR*34 as the master symbol will result in matches for CR134
and CR234, but not CR2345. Entering URGENT** as your master symbol
will result in matches for URGENT, URGENT1, and URGENT12 but not
for URGENT123. This means any wild cards appended to the master
symbol data will result in matches of symbols in variable lengths up to the
master symbol lengths but not over. However, wild cards in the beginning
or center of a symbol (e.g., UR**NT) do not allow for variable symbol lengths.
Wild Card Character allows a user to define a wild card character as part
of the master symbol.

Usage:
Definition:
Serial Cmd:
Default:
Options:
Sequence on No Read is useful when the imager needs to stay in
sequence even if no decode occurs.

Evaluation
In Evaluation, you can view images
currently in the imager, capture and
decode a symbol, save it as a digital
file, and perform histogram and line
scan evaluations.
When you click on the Evaluation tab,
you will see the images that are currently
stored in the imager.
Click Receive to refresh this view.
Click Capture/Decode to display the
current stored image. Only one capture
and decode event will occur, regardless
of read cycle settings.
Click Read to trigger a read cycle. If
there is enough time in the read cycle,
up to 32 good reads (or 6 full-scale
images) can be captured and displayed,
depending on the size of the images,
and depending on the number enabled
in Number of Captures under Capture
Mode in the Camera Setup menu tree
to the left of the tabs.
If you click Save, the current image will
be saved to the location of your choice.
Note: An image can only be saved in
the format in which it was uploaded to
ESP. JPEG images will be saved as
.jpg, and bitmaps will be saved as
.bmp.
When you click the JPEG Image box, notice that the Line Scan button is grayed out.
The JPEG option allows faster captures and transfers, but since the JPEG standard compresses
image data, it is not suitable for the more rigorous demands of line scan evaluation.
JPEG also allows you to adjust the image quality (resolution) by adjusting the sliding tab
between 1 and 100, 1 being the lowest quality and 100 being the highest.
When possible, use the highest quality; when image transfer speed must be increased,
use a lower image quality setting. Adjustments for this setting will depend on your specific
hardware and software limitations.
MINI Hawk High Performance Imager User Manual

Evaluation
Histogram
Usage:
Definition:
Useful in determining quality and contrast of symbols.
A histogram is a graphic representation of the numeric count of the
occurrence of each intensity (gray level) in an image. The horizontal axis
represents the values of gray levels, and the vertical axis represents the
number of pixels for each gray level.
Note: Since histograms are performed in the imager, the results will be saved regardless
of whether the image was uploaded as a JPEG (.jpg) or a bitmap (.bmp).
1. From the Evaluation window, click the Histogram button.
The current image is transferred into the histogram operation. This may take a
moment, since all the relevant pixels are being evaluated intensively.
2. When the Histogram window opens, you may need to expand the window and/or
adjust the scroll bars in order to bring the image into view.
3. To generate a histogram, click and drag your cursor diagonally across the symbol or
a portion of the symbol.
The image will be surrounded by an “area of interest box”, a dashed blue line with red
anchor points that can be selected and moved by placing a cursor inside the box, and
can be resized by clicking and dragging the anchor points.

Line Scan
1. From the Evaluation tab, click the Line Scan button. A window like that shown
below will appear.
2. Drag your cursor horizontally across the image.
This will create a dashed horizontal line. Pixel information and a visual representation
of the dark and light pixels will be displayed below the image.
When you center your cursor over the dashed line, it becomes a double arrow cross.
This allows you to move the line anywhere in the window. You can also use your
keyboard arrows to move the line incrementally in any direction.
As with the histogram, the line scan compares light and dark pixels, but in a spatial
distribution. On the Y axis of the graph below, 0 is black and 255 is white; the X axis
represents the horizontal axis of the symbol as described by the line scan.
When you click anywhere on the graph, a vertical red line appears at that point and its
position and value (in terms of black-to-white) are updated in the Pixel Info table to
the left of the graph (237 in this example). In addition, a horizontal dashed red line is
displayed that indicates the average value.

Calibration
The Calibration interface in ESP is a powerful and intuitive way to optimize the imager’s
performance. It allows the user to control several complex, simultaneous calibration
operations, and to follow the progress of those operations using cues such as progress
bars, real-time representations of calibration values, and other dynamic user feedback.
See Chapter 4, Calibration, for full documentation of this feature.

Window of Interest
The active pixel area of the image sensor is called the Window of Interest (WOI). The WOI
allows the user to select an area of the field of view in which the desired symbol is located.
The programmable window of interest increases decode speed, improves threshold, and
makes it easy to select specific symbols from among several in the field of view. The user
provides the upper-left pixel location and the size of the window to define the Window of
Interest.

Window of Interest by ESP
1. From the Camera menu, click the WOI tab to bring up Window of Interest.
If you haven’t already captured an image, click the Capture and Decode button to
decode the present image. If successful, the Good Read indicator on the WOI tab will
be green and the symbol will appear in the pane below.
Note: You can resize the image by clicking and dragging the ESP window from the
lower right corner. This is useful where very small symbols are being read.
2. Click and drag your cursor over the symbol that you want to isolate for reading.
Notice that the surrounding area goes black.
You can use the handles on the image area that you have just drawn to resize the
region of interest. You can also click on the center of the window of interest and move it.
3. Test the new settings in Read Rate Mode.
Note: To remove the window of interest, click the Reset button or click anywhere in
the WOI pane.
Note that all pixels not in the WOI are defined as black.
Because the imager has far less processing to do in a smaller window, read rates
typically increase dramatically. One possible downside is that the chance of missing
a symbol increases with the smaller window. Always verify that your WOI will be
large enough to allow for any random movement of symbols in your field of view.

Configuration Database
The Configuration Database allows the user to manage multiple configuration profiles. It is
a useful tool in applications that require several different imager configurations to be
applied sequentially, and it allows the user to perform far more complex operations than
would be possible with only one set of configuration parameters.
See Chapter 11, Configuration Database, for full documentation of this feature.

Dynamic Setup
Dynamic Setup
Dynamic Setup is used to calculate image capture timing during a read cycle. Without proper
timing, the imager will not be able to decode all symbols in a read cycle. An external trigger is
used to activate image captures so the user can make timing adjustments as capture events
occur.
Read Rate is
represented
graphically in
real-time as the
user makes
adjustments to
the time delay
between image
captures.
The user can control Capture #, Number of Captures,
and Number of Symbols using these spin boxes.
The Delay Adjustment slider allows the
user extremely precise control of the time
delays between image captures in a read
cycle. Delay values are shown in seconds
in the field above the slider. The Coarse
and Fine Delay Adjustment options
determine whether larger or smaller
adjustment increments will be used.

X-Mode™
The MINI Hawk is equipped with powerful X-Mode™ technology, which provides industry-leading
decode performance on both printed and direct part mark symbols, with minimum configuration
required out of the box. The X-Mode algorithm identifies symbol candidates within the
imager’s field of view and uses sophisticated image processing to decode valid symbols.
In each of the examples below, the X-Mode technique locates a symbol, analyzes the
image gradient to detect areas with changes in reflectivity, grid-maps the image, and ultimately
produces an ideal, reliably decodable Data Matrix.

At 4:1, 4 pixel signals from 2 adjacent rows and columns are combined so that only 1 pixel
is output for every 4 pixels sampled. An image with the dimensions 640 x 480 is scaled to
320 x 240.
Since the resolution of the output image is reduced, the frame rate will increase, but not by
the factor of the image reduction. This is due to the overhead time of digital pixel data
processing and minimum row time requirements of the image sensor.

At 16:1, 16 pixel signals from 4 adjacent rows and columns are combined so that only 1
pixel is output for every 16 pixels sampled. An image with the dimensions 640 x 480 will be

AEC
AEC enables Automatic Exposure Control. In this mode, the optimal setting for exposure
(shutter) is computed and updated for every frame. It may take several frames to adjust
the shutter value to the correct setting. The current camera shutter parameter is updated
at the end of the read cycle (see Camera Settings).
Note: The minimum (slowest) shutter setting will not exceed the frame read-out time of the
current image dimension. For example, a full-size image has a minimum frame read-out
time of 15 ms. Therefore, the slowest shutter that can be achieved is 15 ms, or 1/67.
AGC
AGC enables Automatic Gain Control. In this mode, the optimal setting for gain is
computed and updated for every frame. It may take several frames to adjust the gain
value to the correct setting. The current camera gain parameter is updated at the end of
the read cycle (see Camera Settings).
AEC/AGC
AEC/AGC enables both Automatic Exposure Control and Automatic Gain Control. In
this mode, the optimal settings for exposure (shutter) and gain are computed and updated
for every frame. It may take several frames to adjust the shutter and gain values to the
correct settings.
Important: In this mode, only the Automatic Exposure Control (AEC) is active while the
gain value remains fixed at its minimum setting. The Automatic Gain Control (AGC) only
becomes active if the AEC has driven the shutter value to its minimum (slowest) setting
and the desired image brightness has still not been obtained. When this occurs, the shutter
value will remain fixed while gain is adjusted. The current camera shutter and camera gain
parameters are then updated at the end of the read cycle (see Camera Settings).

Sets the gain value for the image sensor. This setting can be configured
through calibration, which is the recommended method. A higher gain
value will increase the brightness of the image, but the image will be
“noisier”.
Important: Shutter Speed should be adjusted before Gain.
Each of the image sensor’s colors has a separate gain setting, and the
white balance adjustment provides gain offsets for color channels R
(red), G (green), and B (blue) to provide consistent white across the
image. Adjustments to both the R and B channels are usually required.
The gain value that is set here is the base gain value for all colors. If a
color requires additional gain to provide white balance, the offset is added
to this gain value. However, when in the analog gain range, the gain +
offset cannot exceed 42, and when in the digital gain range, the gain +
offset cannot exceed 48. For optimal white balance, avoid setting gain
near these values.
Note: Omron Microscan recommends using only the analog gain range
(0 to 42). Image quality is degraded within the digital gain range (43 to 48).

Focal Distance
Focal Distance
Definition:
Serial Cmd:
Default:
Options:
This setting provides a means for configuring the focal distance of the
imager. The input value is in terms of inches and is divided by 100 internally.
For example, 400 sets the imager to a focal distance of 4 inches. It is
important to note that the imager may not have an exact match for the
focal position requested. The imager has a range of steps that are calibrated
and mapped to focal positions. This input value is matched to the closest
focal position step that the system supports. It is also important to keep in
mind that the resolution of the system is not linear. As the imager’s focal
distance setting increases, the resolution decreases. This effect is offset
somewhat by the fact that the depth of field increases at greater focal
distances.
Standard Density = 400 (4”)
High Density = 400 (4”)
Ultra High Density = 300 (3”)
200 (2”) to 600 (6”)
Note: In the factory, the imager calibrates its focus curve and matches the focus motor
steps to various focal positions. Therefore, each imager has a slightly different focus map
of stepper motor positions vs. focal positions. This allows the user to enter a focal distance
that causes the imager to select the closest stepper motor position required to obtain the
user-defined setting. In this way, there is consistency between imagers for any given focal
distance input.

Definition:
Usage:
Default:
Options:
The 3 Megapixel MINI Hawk’s image sensor captures images in color
and then processes them for optimal decode performance. Color image
processing requires image captures to be filtered, or the R, G, and B cells
to be equalized. This is achieved by applying one of the available filters,
or by performing a white balance with the current camera configuration
before attempting to decode a symbol. This option specifies the filter
method that is applied to the RGB color image to produce a monochrome
image.
General Purpose
0 = Disabled
1 = General Purpose
2 = Horizontal 1D Symbols
Disabled
When Color Filter is disabled, no filter is applied to the captured image. If you are
attempting to decode symbols without a filter, a White Balance may be required to balance
the red, green, and blue cells of the image sensor.
General Purpose
When enabled, the General Purpose filter is applied to the captured RGB image to produce
a gray scale image. The gray scale image can be used in most applications, but the filtering
process increases processing time.
The General Purpose filter should be used when reading 2D symbols, linear symbols that
are not positioned horizontally in the field of view, or a combination of both.
Horizontal 1D Symbols
When enabled, the filter for Horizontal 1D Symbols is applied to the captured RGB image
to produce a gray scale image that is designed specifically to provide the best suitable
image for a linear symbol that is horizontally positioned in the field of view.
The Horizontal 1D Symbols filter should be used when reading linear symbols that are
positioned horizontally in the field of view.

Skew Correction
Skew Correction
Note: Skew Correction does not apply to the High Speed version of the MINI Hawk,
which has a global shutter.
The MINI Hawk’s CMOS image sensor has a
“rolling shutter” mechanism that controls pixel
integration row-by-row, unlike a global shutter,
Full Image Height
which performs light integration of all pixels at
once. When a row of pixels has integrated
light for the amount of time specified by the
Full Image Width
user-defined shutter speed, that row will be
read out. The rows of the image are exposed individually in rapid sequence. As a symbol
moves through the field of view, it is in a different position at each row read-out. This creates
distortion, or “skew”, as in the image shown below. In this image, the symbol is moving
from left to right at a line speed of 40 inches per second. The bottom of the symbol is read
out first while the upper portion is still being integrated, causing distortion along the symbol’s x-axis.
Note: The amount of blur in the image is an effect of shutter speed, and is not a factor in
rolling shutter distortion.
If the symbol enters the imager’s field of view from the top or bottom, distortion will occur
on the y-axis. The image below shows two symbols entering the field of view from the top
at different line speeds. As you can see, this causes the image to shrink along the y-axis.
This is because the symbol is moving perpendicular to the CMOS sensor’s row read-out.
In other words, the bottom of the symbol is read out first, and as the symbol moves information
is lost (the symbol enters pixel rows that have already been processed). This causes the
symbol to appear to shrink vertically.
Note: If the symbol were to enter the field of view from the bottom, the captured image
would be stretched along the y-axis.

Direction of

Full Image Width
The amount of rolling shutter distortion depends upon the amount of time it takes to read
out an image row, and the line speed at which the target object is traveling. Therefore, one
way to reduce skew is to speed up the read-out time per pixel row. This can be accomplished
by reducing the column size of the image sensor.
For example, if the column size is reduced from 640 to 320, the time it takes to read out a
row of pixels from the sensor is reduced by half, and image skew will be reduced by a factor
of 2. As the column dimension of the image is reduced, the effect of rolling shutter distortion
is reduced by the same factor.
Important: Reducing the row size of the image has no effect, because it does not change
the row read-out time. Skew will remain the same regardless of row size.

Distortion is corrected by shifting image rows in the direction opposite the symbol’s
movement on the line. The shift value of subsequent image rows is then increased. These
shift values depend on the speed of the line. The faster the line speed, the greater the
required shift values. More data loss is incurred at faster line speeds.
The image shown below was captured at a line speed of 40 inches per second, and it
shows virtually no inherent skew. The black area of the image is unusable, since the
information was lost as the symbol moved through the imager’s field of view.
The amount of data loss can be reduced by decreasing the image height or the row size of
the image, which reduces the amount of travel represented during the image frame
read-out. Note that the amount of distortion will not be changed, because the object will
have traveled the same distance during the read-out of the target area.

Skew Correction
Symbol Direction
Definition:
Serial Cmd:
Default:
Options:
This feature specifies the direction the symbol is moving through the

first.
Note: Image captures of symbols entering the field of view from above or
below cannot be skew-corrected.
Right
0 = Right
1 = Left
If a symbol enters the field of view from the left, it will be skewed as shown in the image
below. The image is processed from top to bottom, meaning that the top of the symbol is
captured first. The amount of skew is dependent on the speed at which the symbol moves
through the imager’s field of view. The symbol below was captured at a line speed of 40
inches per second.
Additional Notes on Skew Correction
• Autocalibration does not perform skew correction. It is assumed that during autocalibration
the symbol is stationary, so skew correction is not required.
• Images are corrected before they are processed. Therefore, if an image is still pending
at the end of the read cycle, it will not have been skew-corrected.

Important: Pixel Sub-Sampling has no effect when the Image Dimension mode is configured
as Region of Interest in the Database Mode command. This is because the Window of
Interest camera settings are determined by the software based on the Region of Interest
setup. There is no benefit to Pixel Sub-Sampling to increase processing speed when
ROI is configured, because the frame size would need to be increased to make Pixel Sub-Sampling
possible.

Symbology
Definition:
This field allows the user to configure the database to enable specific symbologies
for selected database indexes. Symbology-specific parameters must be
configured with the appropriate symbology command.
For example, if fixed length Code 128 is required, it must first be set up with
the Code 128 command: .
To select a particular symbology, add the number value associated with that
symbology.
Examples:
If Data Matrix and Code 39 are required, the paramater would be: 2 + 16 = 18.
If I 2/5, BC412, and DataBar Limited (RSS Limited) are required, the
parameter would be: 128 + 2048 + 16384 = 18560.
Serial Cmd:

Usage:
Useful in applications where it is necessary to process a single captured
image multiple times using different IP and decode parameters.
Serial Cmd:
Default:
Disabled
Options:
0 = Disabled
1 = Enabled
Disabled
When Image Process Looping is set to Disabled, an image is captured for every database
configuration, whether or not any camera settings have been modified.
Enabled
When Image Process Looping is set to Enabled, the last captured image frame is reprocessed with the new IP and decode parameters. If camera settings have not been
changed from the last capture event, and when a database configuration is loaded to
current, active settings, no new image is captured.
Note: An exception to this is the first database index: a new image is always captured
when the first database index is used. When a camera setting has been modified from one
database setting to the next, a new image is captured. For example, if all database entries
contained the same camera setting values but had different IP and decode parameters, an
image frame would only be captured when the first database configuration was used.

Region of Interest (ROI)
When Image Dimensions is set to Region of Interest, the database image dimension
parameters are IP and decode settings, and they determine the region or area of the
captured image to be processed.
ROI coordinate data is based on the full image size. The WOI of the captured image will be
configured to cover all the ROI settings in the current, active database entry. In the following
example, there are three active database settings, each with a different ROI configuration.
Their coordinates are based at point 0,0 of the full scale image. In this example, DB1 and
DB3 determine the size of the captured image WOI, while DB2 has no impact. The image
WOI is not configurable. It is automatically set up by the database according to the ROI
settings.

Note: Since the ROI parameters are not a camera setting, a change in ROI parameters
from one index to another does not indicate an image capture event.
This feature is intended to be used in conjunction with Image Process Looping, to
allow different regions of a captured image to be processed using different IP and

Customer Default Parameters
Customer default parameters (saved by ) are the same set of parameters as power-on
parameters but are saved in a different, isolated section of NOVRAM. This allows a user
essentially to create a backup set of parameters that can be recalled in the event that the
current parameters or power-on parameters have been accidentally changed or are no
longer desired.
It is important to note that a hardware default does not affect customer default parameters.
For example, a user that has inadvertently changed communication settings and saved
them with a command, may not know the correct settings or have the capability to
communicate within those settings. By first doing an EZ button default or hardware default to
restore the known Omron Microscan defaults, the user can then recall the previous
customer-saved settings with an or command.
Omron Microscan Default Parameters
Omron Microscan default parameters are contained in the firmware and cannot be changed.
Software Defaults
Omron Microscan default parameters can be recalled (loaded into current settings) with
command or recalled and saved for power-on with the command.
Hardware Default
If a software default and reset is not possible, it may be necessary to reset the reader by
shorting (connecting) specific pins. This procedure has the same effect as the
software command.
Important: For this reset to occur, this command must be executed within 60 seconds of a
power-on or a reset.
1. Apply power to the reader.
2. If using an IB-131, locate pins 7 and 11 on the host connector.
Caution: Be certain that the correct pins are located. Connecting the wrong pins could
cause serious damage to the unit.
3. Momentarily connect these wires (or pins) and listen for a series of short beeps.
4. Within 3 seconds, connect them again. A longer beep should be heard. If not, repeat

Learn
Sending the command from ESP’s Terminal will put the imager into a mode of
operation that will cause it to “learn” the next Data Matrix symbol decoded. This mode of
operation will remain active until either a Data Matrix symbol is decoded or the call is
made to disable the mode and revert back to normal operation. Upon decoding a Data
Matrix symbol, the image processing will save pertinent information regarding the target
symbol to allow it to be processed more quickly and consistently.
The data collected by the Learn operation can be saved for a Power-On condition by
sending the command.
Unlearn
Sending the command will cause the imager to discard any information
acquired during a Learn operation.
The Unlearn state can be saved for a Power-On condition by sending the command.

White Balance Calibration
The 3 megapixel MINI Hawk’s default values are appropriate for nearly all applications.
However, the White Balance calibration command will override the pre-configured values
if necessary.
White Balance is a processing operation performed to ensure proper color fidelity in a
captured digital image. The image sensor does not detect light in exactly the same way as
the human eye, which means that some processing or correction of the detected image is
necessary to ensure that the final image realistically represents the colors of the original
image.
White Balance calibration works best if a white object (a piece of paper, for example) is
placed in front of the imager. White and black objects can be present in the field of view
during White Balance calibration, but no color objects can be present.
Important: The White Balance correction adjusts the R, G, and B gain offset values for
every possible analog gain (0 to 42) in the system. Any gain values greater than 42 (43 to
48) will use the factory default White Balance settings.

Bar Code Configuration Mode
Definition:
Serial Cmd:
Bar Code Configuration Mode is a way of programming the imager by
using ECC 200 Data Matrix symbols.
Bar Code Configuration Mode can be entered three different ways:
1. By forcing the imager into Bar Code Configuration Mode by serial command
.
2. By configuring one of the 4 EZ Button positions to Bar Code Configuration Mode.
3. By reading a Data Matrix symbol with a special code word used by ISO/IEC 16022
to signify imager programming. This can be either in a regular read cycle or during a
read rate test. Reading this symbol in the calibration routine will have no effect.1
Once Bar Code Configuration Mode has been entered, the Data Matrix symbols can
be thought of as serial data. You can configure the imager by printing labels in Omron
Microscan’s serial command format. Commands are processed as if the data were
streamed in through the serial port. The imager will acknowledge the symbol with a beep,
green flash, and echo the serial data to the host. If the command causes the imager to
produce more serial output, such as serial verification or counter requests, the data will
be routed to the host port.
Bar Code Configuration Mode can be exited by any reset or command as well
as a or a quick press and release of the EZ Button.
The command to exit Bar Code Configuration Mode can be included as part of the Data
Matrix symbol. For example, try encoding into a Data Matrix symbol.
This configures the imager to enable Serial Trigger Mode, to program a new trigger to end
the read cycle, and to exit Bar Code Configuration Mode with .
To end all EZ Button functions, press the EZ Button once and quickly release.
1. In normal reading modes, it is required to read a special Data Matrix symbol with a special codeword used by
ISO/IEC 16022 to signify imager programming.

This function is limited to 4 characters per output index, so multiple indexes
must be entered in order to insert longer character sequences.
For example, if you wish to insert a 10 character sequence in user-defined
output, you would need three commands with consecutive index numbers,
where the first two character sequence lengths were 4 and the third was 2.
Serial Cmd:

Hex String
Definition:
Specifies a character string that represents ASCII characters to be inserted in
the database entry. Two hex characters are required for every ASCII character
to be inserted in the user-defined output string. These two characters comprise
the hex (base 16) value of the ASCII character.
For example, if you wanted to enter the three-character sequence “Hi!” you
would enter 3 for the length of the string, and a hex sequence of 486921 for
the ASCII sequence to be inserted. (48 = H; 69 = i; 21 = !)
Important: Each pair of hex characters represents one ASCII character. Hex
character pairs range from 00 to FF. Since you are limited to 4 ASCII characters
per insertion per database entry, you are likewise limited to 8 hex characters
per insertion per database entry.
Serial Cmd:
Default:
NUL (00 in hex)
Options:
00 to FF (As many as 4 bytes, or hex pairs.)

Output Filter Configuration
Definition:
Output filtering is a method of providing a set of good read qualifiers and also
providing ordered output. There is a filter for up to the first 10 positions in a
multisymbol output. The first filter corresponds to the first symbol output at the
end of the read cycle. Each filter has has settings for the following four
parameters: Symbology, Symbol Length, Data, and Configuration Database
Number.
Serial Cmd:
Rules for Output Filter Configuration
Output Filter Configuration Rule # 1
Each symbol that is decoded must match one of the filters before it can be saved to a read
cycle record. There is an exception to this rule, however, when the number of symbols
required for a read cycle exceeds the number of active filters. In such a case, unfiltered
symbols can be placed into unfiltered output positions.
For example, if the number of symbols required is 6 but there are only 4 active filters, the
last 2 positions can be filled by any (unfiltered) qualified symbol.
Output Filter Configuration Rule # 2
The same filter setup can be used multiple times.
For example, filters 1, 2, and 3 can be set up to filter Data Matrix symbols, and the output
will occur in the order the symbols are decoded.
Output Filter Configuration Rule # 3
All qualified symbols will be sorted and output in the matching filter position. If a symbol
matches filter 3, it will be output as the third symbol. If a filter does not have a matching
qualified symbol, a No Read message will be output in place of the symbol (assuming the
No Read message is enabled).
For example, if there is not a symbol that meets filter 3’s requirements, then a No Read
message will be output in the third output position.

Definition:
Number of Filters refers to the number of active output filters. 0 disables all
output filters. Any non-zero numeral will enable filtering to be performed
using the filter indexes covered by this value.
For example, if the number of filters is 1, then only filter index # 1 will be
applied. If the number of filters is 2, then only filter index # 1 and filter index # 2
will be applied, etc.

Serial Configuration Commands
Serial Command Format
Serial commands are of two types: utility and configuration.
Rules that apply to both utility and configuration commands
• A less than < and greater than > character enclose the commands.
• Commands and data are “case sensitive.” That is, characters must be entered as upper
or lower case, as specified.
Serial Utility Commands
These are sent during operations and are not followed by or .
Serial Configuration “K” Commands
These begin with a single “K” character followed by a 3-digit numeric character, data
fields, and an initializing command, as follows:
An initializing command or may follow the command. A initializes the
imager’s memory and saves for power-on; an initializes the imager’s memory but
does not save for power-on.
For example, to enable UPC and save the change for power-on, send .
To change Baud Rate and reset without saving changes for power-on, send
.
Serial Configuration Command Conventions
• All data fields (except the last) must be followed by a comma (without a space).
• NUL cannot be used. The characters , and , can be used, but only if entered as hex
pairs (see ASCII Character Entry Modifier on page 3-32).
• All fields preceding a modified field must be included.
• If there is no change in preceding fields, then commas alone can be entered in these
fields. For example, if only the last field in the following command is changing,
can be entered as .
• All fields following a modified field can be omitted. For example, to change Baud Rate
only, send .
A-14
MINI Hawk High Performance Imager User Manual
Appendices
Concatenating Configuration Commands
Commands can be concatenated (added together) in a single string or data block. For
example, enables LRC, sets End of Read Cycle mode
to New Trigger, enables Narrow Margins, and resets the data buffers (without saving the
changes for power-on).
Serial Command Status Request
To ensure that any command was received and accepted, you can send the Show Reader
Status command: .
The status of a specific serial command can be requested by entering the command followed
by a question mark. For example, send to request the status of Postamble.
Entering Control Characters in Serial Commands
To enter control characters within a serial command, hold down the Ctrl key while typing the
desired character.
Example: To enter a carriage return and line feed (^M^J), enter .

Interface Standards
Appendix F — Interface Standards
Interface Standards, established by the Electronic Industries Association (EIA), specify
such things as the signaling voltage levels, maximum cable lengths, and number of drivers.
In the MINI Hawk, selection of interface is made by pin assignment and, in the case of host
communications, by software switching between RS-232 and RS-422/RS-485.
RS-232
RS-232 defines an interface between two devices such as, for example, the reader and
host. It differs from the other interfaces by dedicating individual pins to specific functions
and by requiring both devices to share a common ground line. Since both device chassis
are connected to a common ground, a ground loop potential and the possibility of noise
interference exists. Therefore cable lengths are limited to a maximum of 50 feet (19.7m).
Despite being the most limited, this interface is used frequently because of the large
installed base of RS-232 equipment.
RS-422/RS-485
RS-422, unlike RS-232, measures signals deferentially; that is, the receiver looks at the
potentials between the two receive (or transmit) wires rather than the potential between
signal and ground. As a result, cables, if shielded, can be up to 4000 feet (1219m) in
length. Like RS-232, RS-422 communication is designed for only two devices on a single
line and must have a common ground. It can be used wherever RS-232 is used.
USB
The Universal Serial Bus can connect up to 127 devices to a host at a maximum of 6
megabytes per second (Mbps) of bandwidth.

Cleaning
The MINI Hawk has a hard-coated window that should only be cleaned with alcohol (100%
isopropyl).
Mounting
When mounting the MINI Hawk, do not insulate the stand mount. The bottom panel is
the hottest part of the imager and metal-to-metal contact is necessary for heat dissipation.

Using an External Trigger
Appendix H — Using an External Trigger
Two types of inputs are used on Omron Microscan readers. 5 volt devices have NPN trigger inputs. 10-28 volt devices have optoisolated inputs and outputs.
5 Volt Devices
To trigger a 5 volt device, the input has to be pulled down to “signal ground” (NPN). This
can be done by relays or by a transistor-sourced signal. If a 5 volt device is used in combination
with an IC-332, it must be connected as a 10-28 volt device.
Reader
Reader
Sensor
Sensor
10-28 Volt Devices
To trigger a 10-28 volt device, a small amount of current needs to flow from “Trigger +” to
“Trigger –”. If a PNP source is used, “Trigger –” must be connected to “signal ground”. If an
NPN source is used, “Trigger +” must be connected to the supply voltage.

MINI Hawk Image Output
Appendix J — MINI Hawk Image Output
This section explains how to extract (download) a video-captured image from a MINI Hawk.
Y-Modem Method
The easiest download method is to issue the command to get a list of available
images, then initiate a download sequence using a Y-Modem utility or protocol sequence.
The user will need to issue the first to get an image list response from the imager.
Then initiate the Y-modem download sequence with the command,
where: [path\filename] is one listed from the response.
Retrieve File List
To receive a file list of all images stored in the reader, send the command:
The reader will respond with a list similar to the one below:
In this example, there are 5 images in memory:
/good/0/640x480_gs.bmp
/pending/1/640x480_gs.bmp
/pending/2/640x480_gs.bmp
/pending/3/640x480_gs.bmp
/pending/4/640x480_gs.bmp
• The image will be stored in a directory describing the result of the image.
None assumes root.
/
Root Directory.
/saved
Saved Directory.
Good/
Symbol was decoded and good.
noread/
No symbol was decoded in this image.
Mismatch/
Symbol was decoded, but did not match.
pending
No attempt was made to decode this image.
• The image may be in a numbered sub-folder 0-9 indicating age; 0 = older, 9 = newer.
• The filename will describe the resolution and file type. Valid file types are: .jpg and .bmp.
• The directory locations, file names and file types will vary, depending on reader configuration.
A-32

Appendices
Upload Image
Select a file from the file list above, and then send the command:
.
Now initiate the Y-modem transfer and save the file. Y-modem uploads will vary depending
on the program or language. See the HyperTerminal example below.
Image Upload Using HyperTerminal
• Open the HyperTerminal application by clicking Start, Programs, Accessories, Communication,
and then HyperTerminal.
• Enter a name, and select an icon, then select OK.
• In the connection window, select the COM port, and then click OK.
• Adjust ‘COM Properties’ settings to match the reader (reader defaults shown below).
• Click OK and you will see the HyperTerminal screen.
• Retrieve an image list by sending .
• Request an image upload of the desired file.
• From the menu bar, select Transfer, Receive File…
• Select a file storage location, and then select ‘Y-modem’, click Receive.
• HyperTerminal will upload the image and save the file to the directory specified.

MINI Hawk Image Output
Bit Stream Method
A more difficult method is to parse and decode the bit stream data. The bit stream is a mix
of EXIF format & TIFF format. You will need to use the command.
To load a bitmap, send and the entire grayscale image will load.
To load a JPEG, set arg for the full-size JPEG image, with adjustable quality:
There is only one variable: nnn is a number from 1 to 100, and it represents the image
quality. 1 will load fastest, but will be extremely low-quality. 100 will load slowly, but will be
highest-quality.
= low-quality image, short load time
= high-quality image, long load time
Response Format
The user will need to write an application that can receive the image (8-bit format – 7 data
bit communication will not work), split up the data, and write the file. The data is format info
and then image data, so an ASCII terminal will not work.
The format of the data will be (_ added for readability):
SOH_DATALEN_FRAMETYPE_SCHEMA_DATA_CRC
SOH
= SOH character
DATALEN
= the length of data to follow, 32 bit integer from ‘00000000’ to ‘FFFFFFFF’
FRAMETYPE
=1
SCHEMA
=2
DATA
= image data
CRC
= CRC16 check digit at the end includes SOH, and everything after,
except the CRC

Glossary of Terms
Region — Area of an image. Also called a region of interest for image processing operations.
ROM — See Read-Only Memory.
Saturation — The degree to which a color is free of white. One of the three properties of
color perception, along with hue and value.
Scattering — Redirection of light reflecting off a surface or through an object.
Skew — Rotation of a linear or 2D symbol around an axis parallel to the symbol height on
the substrate. See the illustration under the definition of Pitch.
Substrate — The surface upon which a linear or 2D symbol is printed, stamped, or etched.
Symbol Transitions — The transition of bars and spaces on a symbol, used to detect the
presence of a symbol on an object.
Symbology — A symbol type, such as Code 39 or Code 128, with special rules to define
the widths and positions of bars and spaces to represent specific numeric or alphanumeric
information.
Tilt — Rotation of a linear or 2D symbol around an axis perpendicular to the substrate.
See the illustration under the definition of Pitch.
Trigger — A signal, transition, or character string that initiates a read cycle.
