1. Introduction
1.1 How to download data from scanner
The major difference between the PA500 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 PA500. Inside the PA500 there is an advanced decoding
chip to control SE900 laser engine and to handle barcode decoding. Below is system
diagram for the PA500 barcode:
SE950
Laser
Engine
Decoder
Chip
COM2Advanced
CPU
According to the above diagram, the PA500 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 PA500.
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 PA500’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, PA500 provides USI.DLL to let user control scanner input,
symbologies setting and profile controlling. Please refer to 2 for detail API lists.
USI.DLL is Unitech’s new scanner function library on PA500. For backward compatible
issue, Unitech still provide Scanner3.DLL and ScanKey3.DLL for existing
PT930/PT930SA user to port their software into PA500, but several APIs on
Scanner3.DLL and ScanKey3.DLL have already been removed on PA500. User can
refer to 0and 5 for detail supporting API.

2. USI.DLL – Unitech Scanner Interface DLL
Note : For PA500 programming, it need to dynamically load DLL for using Unitech built-in DLL (Unitech
will not provide *.H and *.LIB for compiler for mobile 5.0 OS), please refer to Chapter 7 for
programming guide.
2.1. Register the application to the USI DLL
Function Description: Register the application to the USI DLL, so that the DLL can communicate with
the application. It will 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"

Parameter: (output)
buffer : LPBYTE : Data buffer for storing scanned data
type : UINT : barcode type which is defined on
Retrieves the scan data into the buffer. Returns the length of characters. It also returns the
barcode type if type is not NULL. Return 0 means that the buffer is too short to hold the
data.
USI_GetData should be called when SM_DATAREADY message is received. Or call
USI_ResetData to discard the data. Both of them will reset the data buffer so that next
scan data can come in.
If the data buffer is not empty and a new scan data occurs, it will be discarded and an
error message SM_ERROR with code of SERR_DATALOST will be sent.
UINT USI_GetData(LPBYTE buffer, UINT len, UINT* type);

3. Control command for decoder chip
Important: This chapter describes low level command for scanner control function. If you
already USI to do scanner programming, you don’t need to care about this chapter. In general, it
is not suggested to use level command to control scanner, because there are timing issue on
serial communication programming , and it is always need communication expert to do that and
it is hard to explain it on document.
When Host prepare to send a command to hamster, it must first check CTS, if CTS is high, then
Host must set the RTS to high then clear RTS to low to wake up the Hamster.
Special Command for control
command Format Comment
Control Esc,80H+SOH(01H) Let Hamster enter slaving status. At this status Hamster just
receives commands and executes it until it receives Release
command or timeout (about 10s). Otherwise, the timeout is
about 1s as the interval of commands.
Release Esc,80H+EOT(04H) Let Hamster exit from slaving status.
Execute/
Enquiry
ACK Esc,80H+ACK(06H) It is from Hamster to Host. If Hamster receive a command and
NAK Esc,80H+NAK(15H) It is from Hamster to Host. Hamster require the Host to re-send
COMMAND FROM HOST TO HMASTER
Command format:Esc,Lh,Ll,n,m,S1,...,Si,BCC
Here: Esc is Escape code(H'1B)
Lh/Ll is command's length when the Lh.b7 is 0, Lh is high byte, Ll is low byte, count from n to BCC.
When Lh.b7=1 it is a two bytes special command.
n is command ID
m is operation: Normally for setting commands the 0 means setting, 1 default, 2 read current setting, 3
special operation. When m=1 or 2, the S1 should be 0 for bits or one character setting. If the setting is a
string, like pre_amble, the read or default command should not contain any Si byte. The special meaning
in a command please refers the command definition.
Si is setting/read data.
BCC: it equals to XOR of all the bytes before the BCC.
Conventions: S1.bj means the number j bit of byte S1.
The expression 1~64:2 means that the number is between 1 and 64, the default is 2.
Notice: Any interval in a command transmit can not exceed 1 second.

there is a result. If Host receive a result but the BCC is wrong,
it can re-send ENQ to re-send result again.

#define kKeybdTriggerEventName TEXT("KeybdTriggerChangeEvent")
#define kKeybdAlphaKeyEventName TEXT("KBDAlphaKeyChangeEvent")
#define LEFT_TRIGGER_KEY 1
#define RIGHT_TRIGGER_KEY 2
gKeyEvents[0] = CreateEvent(NULL, TRUE, FALSE, kKeybdTriggerEventName);
gKeyEvents[1] = CreateEvent(NULL, TRUE, FALSE, kKeybdAlphaKeyEventName);
while (1)
{
WaitForMultipleObjects(2, gKeyEvents, FALSE, INFINITE);
TriggerKeyStatus(LEFT_TRIGGER_KEY);
TriggerKeyStatus(RIGHT_TRIGGER_KEY);
}

7. Dynamic Load DLL
Compiler would not load the DLL while use dynamic load DLL, it help user to load the DLL if it exists while the
application executed. The follow is the example.
Note: Even user does not need include the header and lib file but need to know the function definition.
//////////////////////////////////////////////////////////////////////////////////////////
HINSTANCE g_hUSIDLL;
typedef BOOL (*lpfnUSI_GetScannerVersion)(LPTSTR model, LPTSTR firmware, LPTSTR sdk, int blen);
lpfnUSI_GetScannerVersion USI_GetScannerVersion;
g_hUSIDLL = LoadLibrary(L"\\Windows\\USI.dll");
if (g_hUSIDLL != NULL)
{
USI_GetScannerVersion = (lpfnUSI_GetScannerVersion)GetProcAddress(g_hUSIDLL,
TEXT("USI_GetScannerVersion"));
}
else
{
MessageBox(_T("Load library USI.dll fail"), NULL, MB_OK);
return;
}
TCHAR lstrmodel[50], lstrfirmware[50], lstrsdk[50];
if (USI_GetScannerVersion != NULL)
rc = USI_GetScannerVersion(lstrmodel, lstrfirmware, lstrsdk, sizeof(lstrmodel) + sizeof(lstrfirmware) +
sizeof(lstrsdk));
else
MessageBox(_T("USI_GetScanerVersion does not find"), NULL, MB_OK);
if (g_hUSIDLL != NULL)
FreeLibrary(g_hUSIDLL);

8. Useful function call - without include SysIOAPI.DLL
8.1. Warm-boot, Cold-boot and power off
#include <pkfuncs.h>
#include "oemioctl.h"
// Warn boot
KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);
// Cold boot
KernelIoControl(IOCTL_COLD_BOOT, NULL, 0, NULL, 0, NULL);
// Power off
{
DWORD dwExtraInfo=0;
BYTE bScan=0;
keybd_event( VK_OFF, bScan, KEYEVENTF_SILENT, dwExtraInfo );
keybd_event( VK_OFF, bScan, KEYEVENTF_KEYUP, dwExtraInfo );
}
8.2. Get Device ID
In PA500, an unique ID had been burnt into terminal, user can check it by pressing
“Func”+”9”.
The sample code for read device ID as follow,
////////////////////////////////////////////////////////////////
HWND hDeviceId = GetDlgItem(hWnd, IDC_DEVICEID);
PDEVICE_ID pDeviceID = NULL;
TCHAR outBuf[512], szProductID[100], stringBuffer[100];
BYTE szBuff[255];
DWORD bytesReturned;
char platformID[64];
pDeviceID = (PDEVICE_ID)outBuf;
pDeviceID->dwSize = sizeof(outBuf);
if (KernelIoControl(IOCTL_HAL_GET_DEVICEID, NULL, 0, outBuf, sizeof(outBuf), &bytesReturned))
{
// Platform ID
memcpy((PBYTE)platformID, (PBYTE)pDeviceID + pDeviceID->dwPlatformIDOffset, pDeviceID->dwPlatformIDBytes);
// Device ID for WinCE version
memcpy((PBYTE)stringBuffer, (PBYTE)pDeviceID + pDeviceID->dwPresetIDOffset, pDeviceID->dwPresetIDBytes);
swprintf(szProductID, _T("%s"), stringBuffer);
// Device ID for Mobile version
memcpy((PBYTE) szBuff, (PBYTE)pDeviceID + pDeviceID->dwPresetIDOffset, pDeviceID->dwPresetIDBytes);
swprintf(szProductID, TEXT("%X%X%X%X%X%X%X%X"),
szBuff [0], szBuff [1], szBuff [2], szBuff [3], szBuff [4], szBuff [5], szBuff [6], szBuff [7]);
}
/////////////////////////////////////////////////////////
The code will have platformID holds Platform ID, and deviceID holds Device ID.
