1. Introduction

1.1. Why SDK?

Microsoft had provided several standard SDKs for different WinCE platforms because there are different

supporting modules, GUIs and components in each platform. There are un-predictable problem if user use

improper SDK to compile your application. User should select proper SDK which match to target platform to

develop application program. For Unitech terminal, we also provide SDK for each platform, you can get it

from Technical Binder, or get the latest version from below URL.

http://w3.tw.ute.com/pub/cs/SDK/MR650/MR650SDK.zip

You can also get sample source for Camera, Finger print and wave record/play from below URL

http://w3.tw.ute.com/pub/cs/software/sample_program/mr650/MR650_Sample_source.zip

1.2. How to download data from building RFID proximity reader

The major difference between the MR650 and a standard HPC/PalmPC is barcode input capability. The

WinCE Reference Manual contains no information regarding barcode input. This section will introduce the

programming structure of the barcode sub-system and the programming utility library for the MR650. Inside

the MR650 there is an advanced decoding chip to control SE900 laser engine and to handle barcode

decoding. Below is system diagram for the MR650 barcode:

According to the above diagram, the MR650 communicates with Decoder Chip by mean of serial port COM2.

Its communication parameter is fixed on 38400,N,8.1. Normally, the Decoder Chip is in sleep mode when

COM2 is not activated. When COM2 is activated, the Decoder Chip will start working, and it will decode the

barcode “signal” from the laser engine when the trigger key is pressed. After decoding, barcode data and its

symbology type will be sent directly to MR650.

Many programmers find it difficult to control the Decoder Chip via programming language alone, especially if

they are not familiar with barcode and serial port controls. Because of this, Unitech provides the following

utility library and program for the user or application programmer to control the Decoder Chip:

1. Application program “Scan2Key.exe” is a useful application program that can read input data from the

laser scanner and then directly input the data into MR650’s keyboard buffer. “Scan2Key.exe” makes

barcode data input simple, and can be especially valuable to those programmers not familiar with

COM port programming. User program simply reads the barcode data from the keyboard. For barcode

symbologies setting, you can run Scanner Setting from Control Panel to define all of supporting

symbologies and delimiter.

2. Utility library:

For programming control, MR650 provide USI.DLL to let user control scanner input, symbologies

setting and profile controlling. Please refer to for detail API lists.

1.4. Useful Sample program

You can get useful sample program for VC, C# and VB.NET from below URL

http://w3.tw.ute.com/pub/cs/software/sample_program/mr650/MR650_Sample_source.zip

It includes below functions’ sample program

1. Finger print

2. Camera

3. RS485

4. Audio Wave record and play

2. USI.DLL - Unitech Scanner Interface DLL

2.1. Register the application to the USI DLL

Function Description:

also open and initial scanner port (COM2, for example) and set the scanner to the working mode.

The application should call USI_Unregister to unregister from the DLL after done with the scanner.

Function call:

BOOL USI_Register(HWND hwnd, UINT msgID);

Parameter: (input)

hwnd: Handle of the window to which USI DLL will send messages to report all activities,

including error messages, scan data ready, etc.

msgID: Specifies the message to be posted. DLL will post messages by calling:

PostMessage(hwnd, msgID, msg, param).

The window procedure will receive custom message about msgID and wParam

parameter can be one of the followings:

SM_ERROR_SYS Indicates a system error, which is caused by a call to the system

function. Param contains the error code from GetLastEror().

SM_ERROR Indicates an error. Param contains the cause of error, which can be

on of followings:

SERR_INVALID_HWND: Invalid window handle.

SERR_INVALID_MSGID: msgID cannot be 0.

SERR_OPEN_SCANNER: Open or initial scanner port failed.

SERR_CHECKSUM: Checksum error in received packet.

SERR_DATALOST: New scan data is lost because data buffer is not

empty.

SERR_BUFFEROVERFLOW: Data buffer overflow. The default size is 4K bytes.

SM_REPLY Indicates received a reply. All the responses from the scanner

except the scan data will be notified by this message.

SM_DATAREADY Indicates that scan data is successfully decoded and ready to

retrieve.

SM_ACK Indicates received a ACK.

SM_NAK Indicates received a NAK.

SM_NOREAD Indicates received a No-Read packet.

Note: Scanner port settings are defined in registry as described below:

[HKEY_LOCAL_MACHINE\SOFTWARE\Unitech America Inc.\Scanner\Settings]

"COMPORT"="COM2:"

"BAUDRATE"="38400"

"STOPBITS"="1"

"PARITY"="None"

"CHECKPARITY"="1"
