Altinex CP451-008 manual Operation, Power UP and Shutdown, Preparing Control Software

SPECIAL APPLICATION

OPERATION 7

The CP451-008is 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 CP451-008using a USB drive or network connection.

Once set up, the CP451-008will work trouble-free without user intervention.

7.1 POWER UP and SHUTDOWN

In most installations, the system boots directly into the end-user application the same as the default demo application.

The CP451-008can be powered down using the shutdown/power off option from the START menu, or directly from an AVSnap application using the “App.Shutdown” function.

7.2 PREPARING CONTROL SOFTWARE

It is not recommended to design and create control software directly on the CP451-008. 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 CP451-008needs 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 CP451-008employs 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 CP451-008. If not executed properly, changes will be lost.

The best way to create and edit on the CP451-008is 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 CP451’s “C” drive.

7.3 INSTALLING FILES AND APPLICATIONS

The CP451 utilizes the Windows XP Embedded EWF to protect its internal drive 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.

7.3.1 INSTALLING LARGE FILES

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.
