The  CP450 is designed for use in a fixed 
application where the system boots up directly into 
the user application and does not allow  access to 
the operating system.  The application and GUI 
interface are normally created using a standard 
desktop computer and then installed onto the 
CP450 using a USB drive or network connection.

Once set-up, the CP450 will work trouble-free 
without user intervention.   

The  CP450 boots automatically as soon as power 
is applied. There is no need to press the power 
switch on the bottom of the unit.  In most 
installations, the system boots directly into the 
end-user application.

The  CP450 can be powered down using the 
shutdown/power off option from the START menu, 
or directly from an AVSnap application using the 
“App1.Shutdown” function.

It is not recommended to design and create control 
software directly on the CP450. In most situations, 
it is easier and faster to write and debug control 
software on a standard desktop computer and then
transfer the completed file when ready. However, if 
the CP450 needs to be programmed “in place”, use 
an external USB keyboard and mouse. Simply plug 
in the devices and wait for the system to recognize 
the new hardware and load the drivers.

Remember, the CP450 employs the Enhanced 
Write Filter (EWF) to protect the contents of the 
internal drive. Read the next section carefully 
before attempting to install, create, or edit any data 
files or applications on the CP450. If not executed 
properly, changes will be lost.

The best way to create and edit on the CP450 is to 
use a USB drive plugged into the bottom of the unit 
and make changes directly to the USB drive then 
copy the final files to the CP450’s “C” drive.

The  CP450 utilizes the Windows XP Embedded 
EWF to protect the CP450’s internal memory from 
accidental or unauthorized changes. The EWF 
appears to read and write from the internal drive, 
but executes everything in RAM. All changes WILL 
be lost after reset or shutdown unless the changes 
are committed to memory. Three batch files are 
provided for direct control over the EWF and should 
be used cautiously.

1. COMMIT.BAT – Write to hard drive

This batch file resides on the desktop and writes 
the RAM data onto the hard drive for permanent 
storage  while  EWF is enabled.  Close open 
applications before running this batch file or the 
changes may not be committed to memory.

2. ENABLE.BAT – Turn on EWF

This batch file resides in the root directory and 
turns on the EWF. In this mode, no changes
made to the system are saved unless the 
COMMIT batch file is executed. This is the 
default condition for all CP450s. 

3. DISABLE.BAT – Turn off EWF

This batch file resides in the root directory and 
turns off the EWF. In this mode, the system 
operates like a normal computer reading and 
writing data directly to the hard drive. 

WARNING

When the EWF is turned  off, the user MUST 
shutdown the computer properly. If power is 
turned off or lost without  executing the normal 
shutdown procedure, data can be lost, or 
corrupted, including the BIOS and operating 
system (OS). If the BIOS or OS are damaged, 
the entire system can become unusable. 

If the application or file is too large for the available 
RAM, the operation will be aborted. Use the disable 
batch file before installing the software.  Make sure 
to reset the EWF when done.
