1. Introduction

The ScanPall2 is a high performance, light-weight and compact portable terminal, designed for
daily intensive use.

It is powered by two ‘AAA’ replaceable batteries or one Ni-MH rechargeable battery and is
equipped with a comprehensive set of development tools, including a Windows based
application generator, a "BASIC" compiler and a "C" compiler.

It is provided with an FSTN technology LCD graphics screen, with a resolution of 128x64 pixels,
equipped with backlighting and a contrast control enabling it to be read perfectly, whatever the
ambient lighting.

Its CCD scanner and integrated RS-232 and IrDA communication ports make the ScanPall2
ideal for inventory, stock control, document monitoring, factory floor management, asset
tracking, warehousing and distribution operations.

4. Software organization

The ScanPall2 software system consists of three modules:

• The Kernel module

• The System (Operating System) module

• The Program module

4.1. Kernel Module

The Kernel module forms the heart of the system. It is extremely secure and always protected
by the system. Only a failure of the flash memory or incorrect switching off of the power supply,
during system restart after a kernel update, can destroy the kernel. The Kernel module
guarantees that the user can always download his program, even when the operating system
has been damaged by the user program.

The Kernel module allows the following operations to be performed:

• Program Download

• Update Kernel

• Test & Calibrate

• Version

For further information, refer to section 5.4.

4.2. System Module

The System module is the operating system. It allows the following operations to be performed:

• Memory

• Settings

• Reader

• Battery

• Test

• Download

• Version

For further information, refer to section 5.3.
