Compliance  
Compliance with FCC/Canada Radio Frequency Interference  
Regulations  
Determining FCC Class  
The Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCC  
places digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only)  
or Class B (for use in residential or commercial locations). All National Instruments (NI) products are FCC Class A products.  
Depending on where it is operated, this Class A product could be subject to restrictions in the FCC rules. (In Canada, the  
Department of Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.) Digital  
electronics emit weak signals during normal operation that can affect radio, television, or other wireless products.  
All Class A products display a simple warning statement of one paragraph in length regarding interference and undesired  
operation. The FCC rules have restrictions regarding the locations where FCC Class A products can be operated.  
Consult the FCC Web site at www.fcc.govfor more information.  
FCC/DOC Warnings  
This equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the instructions  
in this manual and the CE marking Declaration of Conformity*, may cause interference to radio and television reception.  
Classification requirements are the same for the Federal Communications Commission (FCC) and the Canadian Department  
of Communications (DOC).  
Changes or modifications not expressly approved by NI could void the user’s authority to operate the equipment under the  
FCC Rules.  
Class A  
Federal Communications Commission  
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC  
Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated  
in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and  
used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this  
equipment in a residential area is likely to cause harmful interference in which case the user is required to correct the interference  
at their own expense.  
Canadian Department of Communications  
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.  
Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.

Watchdog Timer Programming  
This appendix explains the TPC-2012/TPC-2512 watchdog timer  
programming.  
Overview  
You can use the TPC-2012/TPC-2512 watchdog timer to monitor system  
software operation and take corrective action if the software fails to  
function after the programmed period. This appendix describes how to  
program the watchdog timer operation.  
The watchdog timer is built into the W83627HF I/O controller. It includes  
the following programmable functions:  
You can enable and disable the timer via programming.  
You can set the timer interval from 1 to 255 seconds or 1 to  
255 minutes.  
The timer generates an interrupt or resets the signal if the software fails  
to reset the timer after a timeout.  
Watchdog Timer Programming  
The watchdog timer I/O port address is 2E (hex) (the address port) and  
2F (hex) (the data port). You must first assign the register address by  
writing the address value to address port 2E (hex), then write/read data  
to/from the assigned register through data port 2F (hex).

Watchdog Timer Programming  
on WinCE (TPC-2012)  
Windows CE includes a watchdog timer for the TPC-2012/TPC-2512. You  
can access the timer through the WIN32 API. The TPC-2012/TPC-2512  
includes a WDT driver, WDT1:, for enabling/disabling the watchdog timer.  
You must open this driver before using the resources, and then use the  
DeviceIOControl function to enable/disable the watchdog timer.  
This appendix describes DeviceIOControl and it parameters. It also  
includes a programming example.  
DeviceIOControl  
DeviceIOControl sends a control code directly to a specified device driver,  
causing the corresponding device to perform the specified operation. The  
function and its parameters are:  
BOOL DeviceIoControl( HANDLE hDevice, DWORD  
dwIoControlCode, LPVOID lpInBuffer, DWORD nInBufferSize,  
LPVOID lpOutBuffer, DWORD nOutBufferSize, LPDWORD  
lpBytesReturned, LPOVERLAPPED lpOverlapped );  
Parameters  
DeviceIOControl includes the following parameters:  
hDevice  
(in) Handle to the device that performs the operation. Call the  
CreateFile function to obtain a device handle.

Appendix D  
Watchdog Timer Programming on WinCE (TPC-2012)  
dwIoControlCode  
(in) Specifies the operation control code. This value identifies the  
specific operation to be performed and the type of device on which the  
operation is to be performed. No specific values are defined for the  
dwIoControlCodeparameter. However, if you write a custom device  
driver, you can define IOCTL_XXXXcontrol codes, per the CTL_CODE  
macro. You then can advertise these control codes, and an application  
can use these control codes with DeviceIoControl to perform  
driver-specific functions.  
lpInBuffer  
(in) Long pointer to a buffer that contains the data required to perform  
the operation. This parameter can be NULL if the dwIoControlCode  
parameter specifies an operation that does not require input data.  
nInBufferSize  
(in) Size, in bytes, of the buffer pointed to by lpInBuffer.  
lpOutBuffer  
(out) Long pointer to a buffer that receives the operation’s output data.  
This parameter can be NULL if the dwIoControlCodeparameter  
specifies an operation that does not produce output data.  
nOutBufferSize  
(in) Size, in bytes, of the buffer pointed to by lpOutBuffer.  
lpBytesReturned  
(out) Long pointer to a variable that receives the size, in bytes, of the  
data stored into the buffer pointed to by lpOutBuffer. The  
lpBytesReturnedparameter cannot be NULL. Even when an  
operation produces no output data, and lpOutBuffercan be  
NULL, DeviceIoControl makes use of the variable pointed to by  
lpBytesReturned. After such an operation, the variable value has no  
meaning.  
lpOverlapped  
(in) Ignored; set to NULL.  
Return Values  
Nonzero indicates success. Zero indicates failure. To get extended  
error information, call GetLastError.

Appendix D  
Watchdog Timer Programming on WinCE (TPC-2012)  
How to Use the Control Codes  
There are six control codes for the WDT driver operation codes.  
IOCTL _WDT_ENABLE  
Enables the application watchdog timer. By default, if the watchdog timer  
is enabled, the WDT driver automatically triggers itself after the specified  
period, and your application does not need to trigger the watchdog timer.  
lpInBuffer: unused  
nInBufferSize: unused  
lpOutBuffer: unused  
nOutBufferSize: unused  
IOCTL _WDT_DISABLE  
Disables the application watchdog timer.  
lpInBuffer: unused  
nInBufferSize: unused  
lpOutBuffer: unused  
nOutBufferSize: unused  
IOCTL_WDT_STROBE  
Triggers the watchdog. If your application uses IOCTL_WDT_ENABLE  
to enable the watchdog first and then sends IOCTL_WDT_REBOOT to the  
WDT driver, your application must trigger the watchdog once during the  
watchdog timer period. If your application has not triggered at the specified  
period, the device reboots automatically.  
lpInBuffer: unused  
nInBufferSize: unused  
lpOutBuffer: unused  
nOutBufferSize: unused  
IOCTL_WDT_GETTIMEOUT  
Gets the watchdog time setting.  
lpInBuffer: unused  
nInBufferSize: unused

Features in Windows XP  
Embedded (TPC-2512)  
The TPC-2512 supports the Windows XP Embedded platform (commonly  
abbreviated XPe), which is a componentized version of the Windows XP  
Professional edition. This appendix explains the version information and  
the EWF utility for Windows XP Embedded.  
Version Information  
You can access the version information by selecting Start»All Programs»  
Utilities.  
The version information states the current XPE runtime information  
including hardware platform, version, build number, release date, XPE  
QFEs installed in the component database, and Windows XP Pro patches  
installed.  
EWF  
Enhanced Write Filter (EWF) provides an upper filter in the storage device  
driver stack that redirects disk write operations to volatile (RAM) or  
nonvolatile (disk) storage. EWF protects a volume from write access and  
offers the following benefits:  
Write-protects one or more partitions on your system.  
Enables read-only media, such as CD-ROM or flash, to boot and run.  
Prolongs the life span of write-sensitive storage, such as  
CompactFlash.  
To disable/enable EWF, go to Start»All Programs»Utilities and select the  
EWF tab. The default setting is disabled.  
When EWF is enabled, the C:partition is protected from any disk writing.  
In this mode, any changes on the C:partition (including modifications to  
files or the registry) are redirected to memory. Thus, these changes are  
discarded in the next system startup. You can manually enable this mode  
after finishing all system changes such as installing your applications or  
adjusting system settings.
