IR-320 System Overview
Rev. C
Operation Modes
The IR-320 has the following five operation modes.
(1) Mechanical Off Mode
In the mechanical off mode, the main power switch is off. No power is supplied to the IR-320
main body, and the power in all circuits is off.
To turn on the power to the IR-320, first turn on the main power switch.
(2) Soft Off Mode
In the soft off mode, only the main power switch is on. Items such as the clock circuit, backup
circuit, and power management circuit inside the IR-320 are on in the standby state. To save the
backup data after the power is off, the main power switch should remain on.
When the system is in the soft off mode, it can be put in full on mode by software, by pressing
the soft off switch, by a wake up signal from the LAN or by a ring signal from the modem.
(3) Full On Mode
In the full on mode, the main power switch and the soft power switch are on. The system is in
the normal operating state. Even if the system is started by a wake-up request signal from the
LAN, the full on mode is produced.
To turn off the IR-320 power, turn the power off from the software. The power-off operation
differs slightly, depending on the setting of the APM driver. See Chapter 4 “Utility“.
(4) Video Off Mode
When no input operation is performed for a given period of time during operation in the full on
mode, only the LCD and the backlight circuits are turned off, thus extending the service lifetime
for the LCD peripheral parts.
Depending on which operating system (OS) is used, the setup method for the time for transfer to
the video off mode differs. The setup method for each OS is described below.
Windows NT does not support the video off mode; therefore, the LCD and the backlight circuits
cannot be turned off during operation.
When “Power Button Tool“ is installed, Win 98 and Win 2K can realize “No-Operation“.
In the video off mode, the unit immediately returns to the full on mode when input is received
from the keyboard, mouse, or touch panel.
