Casio IT-2000W manual Relationship between OFF Factors and on Processes

This terminal has the Auto Power ON function which automatically starts the system. This Auto ￿Power ON function can operate in one of the following three ways:

Auto Power ON function (only affects the resume process) activated by alarm

The system power can be turned on (resumed) at the specified time by means of an alarm. However, this will not function if the next start-up method is set to the boot process in the system

￿library.

Auto Power ON function activated by the RING signal

This function can be used if a modem is connected to the 14-pin expansion interface. In this case the system power can be turned on by the detection of the RING signal from the modem. Remember that Power ON by means of the RING signal is prohibited by default. Execute this function using the system library to enable the Power ON function to be activated by the RING signal. System operation after the power is turned on follows the sequence described in "

￿Relationship between OFF Factors and ON Processes" on this page.

Auto Power ON activated by mounting on the I/O Box

The system power can be automatically turned on as soon as this terminal is mounted on the I/O Box. However, this function is effective only if power is supplied to the I/O Box. This function is enabled by default, however, it can be disabled using the system library. System operation after the power is turned on proceeds according to the sequence described in "Relationship between OFF Factors and ON Processes".

Relationship between OFF Factors and ON Processes

As described in the above overviews, the ON process (the Boot process or Resume process) will run differently depending on the last OFF factor (what caused the OFF) and the conditions that existed when the power was turned OFF. The following table shows the relationship between the OFF factors and the ON processes that take place the next time the power is turned on.

OFF factor	If an application is running	If the System Menu is on
Power switch	Resume process or application	Application boot process
Auto Power OFF	boot process (see note below)
Software OFF
Low battery voltage
(LB1)
Low battery voltage	Resume process
(LB0)
RESET switch pressed	System menu boot process	System menu boot process

Note:

Depends on whether the resume function is enabled or disabled. With this setup the next boot process can be designated as the Application boot process.
