Introduction
The 5X10/5X80 Software Development Kit (5X00 Series) provides a set of libraries, tools, and sample source code to help soft-
ware developers create an interface between their host system and a Honeywell miniature image scan engine. The 5X00 Series
consists of:
•
•
•
The API Definition and Documentation
API Libraries
Sample Code
Features of the 5X00 Series
•
The 5X00 Series contains software libraries that interact with image/data capture engines using a documented API
(Application Programming Interface). The API functions are defined on a higher level so they can be easily understood and
integrated into your applications, so you don’t have to learn minute details of the engine interface protocol. You simply compile
your code with the library header files and link in the library for your platform. Afterward, all engine functionality is at your
disposal.
•
•
The image/data capture engine is easily integrated into a variety of host platforms.
The 5X00 Series captures images and returns them as unformatted data, or as one of the standard file formats (BMP, TIFF,
and JPG). Captured images can then be saved to disk and easily imported into a variety of common tools and applications.
A single API is used for all Honeywell decoding engines. The libraries for all engines are identical for a given host platform.
There are different libraries for each platform, but the API interface is the same for all of them, so you only need to learn a
single API.
•
®
®
®
•
Libraries are available for the Microsoft Windows family of operating systems. This includes both the Windows CE
®
®
operating system, Windows 9x, and Windows NT derivatives.
•
•
Sample code is included that demonstrate how to use specific aspects of the 5X00 Series, as well as the buildable source
and executable code for a demo application.
The communication driver library is separate from the main engine API library.
Target Operating Systems for the 5X00 Series
The 5X00 Series is designed for use with the following operating systems:
®
®
•
Windows CE versions WinCE 4.2, WinCE 5.0, Windows Pocket PC 2000, and Pocket PC 2002 supporting the following
processors:
Pocket PC 2000ARM, MIPS, SH3
PocketPC 2002ARM
PocketPC 2003ARMV4

Interface Diagram
The following diagram shows the interface between the 5X00 Series and the Image Engine:
User Application
SDK Driver Interface Layer - hhpImgrSdk.dll
SDK API Interface Layer - commDrv.dll
OS Communications Driver
Physical Connection: RS-232, USB, etc.
Image Engine
5X00 Series Library Files
The SDK API and SDK communications layers are provided in the dynamic link libraries, hhpImgrSdk.dll and commDrv.dll,
respectively. The library link file hhpImgrSdk.lib and the include files hhpImgrSdk.h, hhpSymCfg.h and hhpImgrCfg.h are also
provided. In order to use the 5X00 Series, you must include hhpImgrSdk.h in any source files that call the SDK functions. The
library include files must be in the include path for the application’s project. This means that the files must either be in the
source file build directory, or in the developer’s Studio include path. Also, the library link file, hhpImgrSdk.lib, must be added to
the application project link list and link path. Since the .dll and .lib files are operating system and processor type dependent,
care must be taken to use the proper files for the chosen target environment.

5X00 Series API Library Summary
The following is a summary of the API functions. The full description of each function is found on the page noted.
Core Functions
Page
Core Function
Error Management Function
Summary
Returns a descriptive text string for the specified SDK error code.
Connection Functions
These functions open, close, and verify a connection to an imager.
Establishes and initializes a connection to the imager at the specified port and
connection settings.
Closes down the open imager connection.
Checks if the connection to the imager is valid.
Establishes and initializes a connection to the imager at the specified driver
name and connection settings.
Asynchronous Notification and Control Functions
Image and barcode capture can be either blocking (synchronous) or non-blocking (asynchronous).
In blocking (synchronous) mode, the SDK function call does not return until the barcode or image is received, the request times
out, or an error occurs. In non-blocking (asynchronous) mode, the capture call returns immediately. Your application is notified
of the completion when either a barcode or an image was received, the time-out for the call was reached, or an error was detected.
You can specify which notification methods you wish to receive.
Your application can subscribe to one or more of the following notification methods: Windows Event, Windows Message, and/or
Callback Function. When notification is received, your application can call hhpGetAsyncResult (see page 2-4) to retrieve the
return code as well as the image, barcode, or text data. The asynchronous interface is also the manor in which imager-initiated
barcode capture data, such as from a hardware trigger, is returned.
There is also a cancel function (see hhpCancelIo on page 2-2) that allows you to cancel any ongoing operation. You should be
aware that when the callback function method is used, any processing done during the callback is run within the context of the
SDK’s asynchronous read thread. This means that the SDK is unable to receive images or barcodes until the callback returns.
Cancels any synchronous or asynchronous I/O in process.
Retrieves the results (image/barcode, etc.) of an asynchronous
I/O event.
Allows the application to select how it wishes to be notified on completion of
an asynchronous I/O event.
Imaging and General Configuration Functions
The imaging and configuration functions provide a simplified API for modifying the imager setup, image/barcode capture
configuration, and symbology configuration. In order to limit the number of functions a developer must master, the design
philosophy is to allow configuration control using only a small number of setup functions. The imager configuration is broken down
into functional groups with structures containing the configurable items for each. Individual configuration items are specified within
structures by use of a bit field mask. In this way, single configuration items can be read or written using minimal communication
traffic. There are functions for reading and writing parts or all of the HHP_CONFIG imager configuration structure as well as
writing the setup/configuration for individual symbologies. If the specified symbology is not available in the imager’s version of
the symbol decoder, (e.g., Data Matrix in a linear and PDF417 decoder), the symbology functions return
RESULT_ERR_UNSUPPORTED. Finally, to facilitate easy configuration management from device to device and application to
application, the 5X00 Series also provides methods for retrieving and setting the whole imager configuration as a single stream
so it can be saved to disk and restored at a later time.
Retrieves a single configuration group or whole imager configuration from the
imager.
Retrieves the current whole imager configuration as a single buffer. This
buffer can be saved to a file and later restored.

Core Functions (Continued)
Page
Core Function
Summary
Retrieves the imager settings (fixed) for image size, image bit depth, and
maximum message length.
Reads information about the image engine contained in the image engine
PSOC.
Sets a selected symbology, or all symbology configurations, to their default
values.
Writes some or all of the configuration items for a single configuration group or
for all configuration groups, with the exception of version and communication
groups.
Writes an entire data stream of programmable parameters from a previous
call to hhpReadConfigStream.
Symbology Configuration Functions
These functions allow you to read and set the symbology configurations.
Enables or disables a single symbology, or all symbologies.
Retrieves the current or default symbology configuration for a specified
symbology, or for all symbologies.
Returns the specified symbology range maximum and minimum values.
Defaults a single symbology, or all symbologies.
Writes some or all of a single symbology, or all symbologies’ configuration
items.
Barcode Capture Functions
The 5X00 Series captures barcodes from imagers that have hardware triggers or some other non-SDK initiated barcode captures
without having to poll the imager to see if there is any data to read. This allows the imager to be put into low power mode without
having to wake up to answer the polling message.
All barcode result strings are returned in TCHAR arrays, which, if running on a WinCE device or if using a Unicode Desktop build,
are 2 bytes per character. You can specify a Unicode code page other than the default ANSI code page (CP_ACP).
Initiates a synchronous (wait for finish before returning from call) or
asynchronous (return immediately) barcode capture. Decoded data returned
is translated by code page and locale.
Specifies the code page used to convert the barcode characters to Windows
text. The default is the ANSI code page.
Initiates a synchronous (wait for finish before returning from call) or
asynchronous (return immediately) barcode capture. Decoded data returned
is unmodified 8 bit (ASCII) data.
Image Capture Functions
The image capture functions provide both synchronous and asynchronous operation.
A synchronous capture is specified by setting the bWait parameter of hhpAcquireImage or hhpGetLastImage to TRUE. For
synchronous operation, the function will not return until an image has been captured and transferred (hhpAcquireImage), just
transferred (hhpGetLastImage), or an error has occurred.
Asynchronous captures are specified by setting bWait to FALSE. The function call returns immediately and the caller is notified
on request completion as long as at least one of the event notification methods has been enabled. You can receive transfer
progress updates by Windows messages or by providing a pointer to a DWORD. Both hhpAcquireImage and hhpGetLastImage
allow the caller to override the current imager transfer configuration in the imager.
Initiates a synchronous (wait for finish before returning from call) or
asynchronous (return immediately) image capture. The image acquisition and
transfer parameters can also be specified.

Core Functions (Continued)
Page
Core Function
Summary
Initiates transfer of the last image captured. (This includes images captured
during barcode scan.) The call can be made synchronously or
asynchronously, and the transfer parameters can be specified.
Intelligent Imaging (Signature Capture) Functions
Intelligent imaging is barcode capture combined with an image window capture. The image window is cut from the same image
used to capture a barcode. This is how the SDK provides the ability to capture a signature associated with a barcode. In fact, a
successful barcode capture is required before the intelligent image window is sent by the imager. You can specify whether the
image is returned grayscale or black and white.
Barcode capture combined with an image window capture.
Captures portion of the image in which a barcode is decoded.
Miscellaneous Functions
Turns on illumination LEDs, Aimers, (and sound beeper for imagers that have
one) outside the image or barcode capture.
Sends menu commands to the imager.
Upgrades the current imager firmware with a new firmware file.
Allows you to specify the name of an OEM dll file. This file can contain some
or all of the OemDll exports that provide support for hardware trigger and low
power mode hardware lines.
Data Types, Structures, and Enumerated Types
The 5X00 Series API uses structures (see Structures and Mask Definitions beginning on page 4-1) and enumerated types (see
Enumerated Types and Definitions beginning on page 3-1) extensively . The definitions are in the include files in the 5X00
Series package. All 5X00 Series-specific structures have a dwStructSize member that must be set to sizeof( struct name ).
This insures that the structure being passed to a given function is the structure type expected by the function and, if writing is
done to the structure, that the structure size boundary is not exceeded. Furthermore, all imager configuration structures (except
the all inclusive structure HHP_CONFIG) have a DWORD member dwMask. The mask allows you to specify only certain mem-
bers within a structure. Set the mask value by ORing together the appropriate masks for the given structure for the particular
items within the structure that should be read/written. Samples of programs that demonstrate this can be found in Program
®
®
Samples beginning on page 6-1. This technique is also used by Microsoft in their Windows SDK (for example, see Win-
®
dows SDK structure CHARFORMAT).
®
The following Windows data types are included for clarity.
Note:
A “P” in front of a data type means a pointer to the type.
Windows Data Types
BOOL
32 bit signed integer used by most Microsoft SDK functions in place of a true Boolean.
BYTE
8 bit unsigned variable.
DWORD
32 bit unsigned integer variable.
A Windows WIN32 handle type. Returned from opening files, creating events, semaphores, or
mutexes.

API Function Descriptions
The following is an alphabetic listing of each API function with its complete description and a prototype for each function. All API
functions (with the exception of hhpEngineConnected (page 2-4) return a result code of type Result_t. See Error Codes on page
hhpAcquireImage
This function causes the imager to capture an image and transfer it to the host. Values to be used from the structures are
specified by setting the appropriate bit mask for each item in the structure’s mask member.
hhpAcquireImage(
BOOL bWait
)
Parameter
Description
pImg
Pointer to an HHP_IMAGE structure if bWait is TRUE. If bWait is FALSE, the parameter
is ignored and should be NULL.
pImgTrans
Optional pointer to an HHP_IMAGE_TRANSFER structure. This structure overrides (just
for this call) the current imager configuration, and specifies the pixel subsample, cropping
rectangle, transfer compression type, compression factor (for JPEG lossy transfer), and
progress notification method. If this parameter is NULL, the current imager configuration
settings are used except for the progress notification methods that must be specified for
each call if notification is desired.
pImgAcqu
bWait
Optional pointer to an HHP_IMAGE_ACQUISITION structure. This structure overrides
(just for this call) the current imager configuration, to specify and configure the image
capture method (type of autoexposure control or manual mode). If this parameter is NULL,
the current imager configuration settings are used.
If TRUE, do not return until the image is received or an error occurs. If FALSE, return
immediately. One of the event notification methods must be enabled to receive notification
hhpAcquireIntelligentImage
The location of the window of interest must be provided in units of minimum barcode widths. This allows the imager to grab the
same physical window, no matter how far the imager is from the page. The resultant image window is always squared with the
X and Y axis of the returned image, so even if the barcode page is rotated relative to the imager, the resultant image appears
square to the image edges.
There is only one intelligent image call that supports both synchronous and asynchronous capture. If synchronous capture is
used, all members of this structure must be valid. If asynchronous capture is used, you will receive
HHP_INTELIMG_BARCODE_EVENT for the barcode data, and HHP_INTELIMG_IMAGE_EVENT for the image data. The
barcode data is returned in a normal barcode structure (HHP_DECODE_MSG), while the intelligent image data is returned in an
HPP_IMAGE structure.
Note:
Since the HHP_INTEL_IMG structure requires that image offsets and size be specified in barcode units, the
HHP_INTEL_IMG structure has a size member that allows you to specify (in pixels) the maximum allowable width and
height for the returned image.

immediately. One of the event notification methods must be enabled to receive notification
hhpCancelIo
Cancels the current barcode or image capture.
hhpCancelIo(
void
)
hhpCaptureBarcode
This function causes the imager to capture images and attempt to decode them. Decoded data returned is translated by code
page and locale. Barcode capture can be synchronous or asynchronous. Synchronous capture is specified by setting the bWait
parameter hhpCaptureBarcode to TRUE. In this case, the function will not return until a barcode is read, an error occurs, or the
decode timeout is reached. Asynchronous capture is specified by setting the bWait parameter hhpCaptureBarcode to FALSE,
or whenever a barcode capture is initiated other than by the 5X00 Series (e.g., from a hardware trigger). In order to be notified
of an asynchronous transfer, you must enable at least one of the notification methods (see hhpSetAsyncMethods on page 2-10).
hhpCaptureBarcode(
DWORD dwTimeout,
BOOL bWait
)
Parameter
Description
pDecodeMsg
Pointer to an HHP_DECODE_MSG structure if bWait is TRUE.
If bWait is FALSE, the parameter is ignored and should be NULL. (HHP_DECODE_MSG
will be passed to hhpGetAsyncMethods() call instead.) The function returns immediately,
and you are notified when symbols are decoded, an error occurs, or decoding times out
(no barcode) using the specified event notification method(s).
dwTimeout
bWait
Maximum time (in milliseconds) to attempt to decode before declaring a no decode. A
value of CURRENT_DECODE_TIMEOUT specifies that the timeout is whatever is
currently set on the imager. A value of 0 indicates no timeout.
If TRUE, wait for capture to complete before returning. If FALSE, one of the event
notification methods must be enabled to receive notification upon completion.
hhpCaptureRawBarcode
This function causes the imager to capture images and attempt to decode them. Decoded data returned is unmodified 8 bit ASCII
data. Barcode capture can be synchronous or asynchronous. Synchronous capture is specified by setting the bWait parameter
hhpCaptureRawBarcode to TRUE. In this case, the function will not return until a barcode is read, an error occurs, or the decode
timeout is reached. Asynchronous capture is specified by setting the bWait parameter hhpCaptureRawBarcode to FALSE, or
whenever a barcode capture is initiated other than by the 5X00 Series (e.g., from a hardware trigger). In order to be notified of
an asynchronous transfer, you must enable at least one of the notification methods (see hhpSetAsyncMethods on page 2-10).

descriptions.
hhpGetErrorMessage(
Result_t nErrorCode,
int nMaxChars
)
Parameter
nErrorCode
ptcErrMsg
nMaxChars
Description
Error code returned from one of the other 5X00 Series functions.
TCHAR buffer to hold error message string.

Parameter
Description
pImg
Pointer to an HHP_IMAGE structure if bWait is TRUE. If bWait is FALSE, the parameter
is ignored and should be NULL.
pImgTrans
Optional pointer to an HHP_IMAGE_TRANSFER structure. This structure overrides (just
for this call) the current imager configuration, and specifies the pixel subsample, cropping
rectangle, transfer compression type, compression factor (for JPEG lossy transfer), and
progress notification method. If this parameter is NULL, the current imager configuration
settings are used except for the progress notification methods that must be specified for
each call if notification is desired.
bWait
If TRUE, do not return until the image is received or an error occurs. If FALSE, return
immediately. One of the event notification methods must be enabled to receive notification
on completion.

Structures and Mask Definitions
Important: All structures have a dwStructSize member that MUST BE SET before calling any of the 5X00 Series API functions.
This insures that the proper structure has been passed to the function being called.
Most structures have a dwMask member. This specifies which structure members are active (to be read or written). Select
structure items by ORing the individual structure masks for each of the items you wish to be active together.
Symbology Structures and Defines
All symbology structures are 1 of 3 possibilities.
Important: Symbology configuration definitions for each symbology are ORed together in the dwFlags member of the symbology
structure. The applicable flags are dependent on symbology. For example, Aztec Code accepts only
SYMBOLOGY_ENABLE, while Postnet accepts SYMBOLOGY_ENABLE and SYMBOLOGY_CHECK_TRANSMIT.
#define SYMBOLOGY_ENABLE
0x00000001
0x00000002

OEM-Configurable SDK Functionality
The 5X80 accommodates a variety of PDA/PDT, static mount, and "gun" type installations, so the 5X00 Series has included the
flexibility to modify some SDK behaviors. You can provide a DLL that affords the SDK access to the hardware trigger, hardware
sleep lines, and access to the open driver handle and registry entries, which can be used to specify high speed baud rates
(greater than 115200). You can also specify whether to force a Y-modem communications protocol for image transfers.
OEM Supplied DLL
The OEM DLL interface is described in SDK header file OemDll.h. The DLL can export some or all of the available functionality.
If the DLL is named ImgrHwrLines.dll and is located in the default library search path, it will be loaded automatically by the SDK.
Otherwise, it can by loaded manually by calling the SDK function hhpSetHardwareLineDllFileName. The DLL exports are
described in the following list:
ConfigureCommPort
ConfigureCommPort performs any special driver configuration that needs to be done to support the specified communication port
settings. Configuring the communications driver requires the current driver handle, so you must also support
SetCommDriverHandle(). The function is called by the SDK whenever you set/change the communication port settings. It is
called after the SDK is finished processing pConfig, so any changes you make will not be overridden.
bool ConfigureCommPort(
PCommPortConfig pConfig
)
Parameter
Description
pConfig
The communication settings requested. The CommPortConfig structure contains:
Baud Rate, Data Bits, Parity, Stop Bits and RTS control.
ImagerPoweredDown
ImagerPoweredDown checks the imager powered down hardware line for the imager power state. The powered down hardware
line is active high. ImagerPoweredDown returns true if the hardware line is high, false if it is low.
bool ImagerPoweredDown(
void
)
ModifyCommPortDCB
ModifyCommPortDCB receives the RS-232 configuration (DCB) structure just before it's sent to the serial driver. You can then
modify the RTS/CTS and DTR/DTS settings if they are used for the imager’s power or trigger.
void ModifyCommPortDCB(
LPDCB lpDCB
)
Parameter
Description
LPDCB lpDCB
Structure used by windows to configure a serial port.
SetCommDriverHandle
SetCommDriverHandle receives the handle to the open communications port. The handle can then be used to access private
driver ioctl calls.
void SetCommDriverHandle(
HANDLE hDriver
)
5 - 1
Download from Www.Somanuals.com. All Manuals Search And Download.
Parameter
Description
hDriver
The current handle to the open driver used to communicate with the imager.
SetHardwareTrigger
SetHardwareTrigger triggers the imager hardware trigger line, depending on bEnable. The hardware trigger line is active low.
void SetHardwareTrigger(
bool bEnable
)
Parameter
Description
bEnable
If true, set trigger line low to trigger imager. If false, set trigger line high to turn off trigger.
WakeUpImager
WakeUpImager toggles the imager hardware wakeup line from low to high, delay, (see Integration Manual for timing), then from
high back to low.
void ImagerPoweredDown(
void
)
Registry Entries
There are two registry entries used to modify the SDK default behavior. The values are both located in the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Hand Held Products\MatrixDemos.
Baud Rate
The SDK will not normally allow high speed serial connections (connections greater than 115200 baud) unless it recognizes the
driver name in the registry. The first registry value, BaudRate, specifies the first baud rate at which the demos will attempt to
connect. It also overrides the normal block that sets high speed baud rates. This lets you specify a baud rate greater than
115200.
ForceHmodem
The SDK does not normally use its Y-Modem variant, Hmodem, if a high speed serial connection is specified. However, if your
driver does not support true hardware RTS flow control, there is a substantial risk of communication buffer overruns. These
overruns can cause data loss, especially during image transfer. The registry value ForceHmodem lets you force the use of the
communications protocol, preventing data buffer overflow.
