1. Overview
1.1 Features of System
1.1.1 Development Concept
The IT-2000 is a data collection terminal for business use. After years of refinement Casio
Computer Co., Ltd. has developed its hand-held type terminals so that they yield high speed and
a high functionality in comparison to general personal computers. This allows improved efficiency
in software development.
It has adopted the IBM PC/AT architecture and incorporated an IBM PC/AT compatible BIOS. It
uses MS-DOS Ver. 6.22 for its OS. This has drastically improved the software development
environment and compatibility to IBM PC/AT family applications.
The adoption of a power-saving type 32-bit CPU, the Intel 80486GX, allows the terminal to operate
continuously for eight hours (when the backlight is off).
1.1.2 Hardware
Global IBM PC/AT architecture standard is adopted.
Compact design: 85 (W) x 196 (L) x 30 (H) mm, 430 g (approx.)
Uses a 32-bit CPU (Intel 80486 GX) for 25 MHz high-speed operation.
High-resolution (192 x 384 pixels), large-size liquid crystal touch panel.
Supports various interfaces, including RS-232C (8-pin, 14-pin), IR, and PC card.
High environmental adaptability: Operation temperature at between -5 and 50 , water splash
proof capability conforms to the IPXII standard, etc.
Uses a small-size, large capacity lithium-ion battery pack as the main battery.
Incorporates a large capacity flash ROM drive as the user drive.
1.1.3 Software
MS-DOS Ver. 6.22 as the operating system.
IBM PC/AT-compatible BIOS makes it easy to develop user application programs.
Uses APM 1.1, for advanced low-power consumption capability.
