A-4 Hardware Specifications Rev. D

Real-time Clock

The real-time clock (RTC) is built in the chipset (Intel 82801DA). The RTC has a clock function

and CMOS RAM function, and is backed up by the built-in lithium primary battery even when

the system is turned off.

CMOS RAM stores the system setting information such as the clock and power management

settings. To clear CMOS RAM, turn the power off and short 2-3 of JP1601 on the main board.

To set the clock, use the BIOS Standard CMOS Features menu.

Clock precision: ±100 seconds per month.

Video Controller

The video controller in the chipset

The video memory uses the part of the main memory, and the color count settings shown below

are possible for each resolution.

Dual display is available with Windows function. Another screen can be displayed on an

external display as well as the LCD.

It has a screen stretching function. When the VGA screen is displayed on the LCD with SVGA or

XGA, the screen in expanded to display without reducing the size.

POS Controller

The POS controller is built in the LCD unit. The POS controller sets and controls the touch panel,

28 Key POS keyboard, and MSR. It also stores the definition data of the 28 Key POS keyboard

and MSR. The POS controller is connected with the IR-700 through an USB port and sends the

input data from these devices to the IR-700 through it.

Before using the 28 Key POS keyboard, it is necessary to set the definition data in the POS

controller. (Refer to Chapter 4 "28-key Definition Utility" for more information.)

To use the MSR or touch panel, it is not necessary to set the definition data in the POS controller.

If any other settings are necessary, set them before use. (Refer to Chapter 4 "MSR Setting Utility"

for more information.)

Up to two Serial ATA 3.5" HDDs can be installed. The rear structure of the system enables you to

replace them easily.

The model with two HDDs can establish a RAID system to operate the system continuously and

to improve security by preventing a data loss.
