1. Introduction
The CPT-720 Portable Terminal is a durable,
versatile, rugged data terminal designed for all-
day, everyday use. It is supported by a rich set of
development tools, including a Windows-based
application generator, “C”and “Basic”compilers.
In order to satisfy heavy-duty applications, the
CPT-720 can withstand 1.5-meter drops onto
concrete and can also be operated under extreme
temperature.With its integrated Laser/LRCCD
barcode scanning unit, expandable data memory,
and multiple communication interfaces, the CPT-
720 is today’s most flexible and reliable data
collection terminal.

4. Software Organization
The system software of CPT-720 Portable Terminal consists
of three modules: the kernel module, the system module and
the application module.
4.1 Kernel module
Kernel module is the innermost core of the system. It has the
highest security and is always protected by the system. Only
the failure of flash memory or improperly power off during
system restart after updating kernel will the kernel be
destroyed. The kernel module ensures that user can always
download their own program even the operating system was
crashed by user’s program. It provides the following
services:
ŸProgram download
ŸUpdate kernel
ŸTest & Calibrate
For detail operations, please refer to section 5.4.
4.2System module
The system module provides the following system services
ŸMemory
ŸSetting
ŸReader
ŸBattery
ŸTest
ŸDownload
ŸVersion
For detail operations, please refer to section 5.3.

11
4.3Application module
The Application module runs on top of the System module.
The CPT-720 Portable Terminal is preloaded with an
application module that runs upon powering the unit up. The
following menu will be shown:
ŸExecute
ŸClear Data
ŸTransmit Data
ŸDownload Settings
The arrow keys can be usedto select the menu item, and
execute it by pressing the ENTER key. The function and
meaning ofeach item are as follows:
Execute Start the data collection process.
A new screen appears after Executeis
selected and the ENTER key is pressed,
showing the following two prompts:
Item:
Qty:
Data can be input from keypad or barcode
reader. Pressing the ENTER key after the
Quantity has been entered will save the
data and the system will show the same
prompts until the ESC key is pressed,
which will bring back the main menu.
Clear Data To clear all the transaction data.
A submenu will be shown asking to
confirm this action. Once executed, the
transaction data will be lost and can not be
retrieved. To abort this operation, Nomust
be selected when asked to confirm the
operation or by pressing the ESC key to go
back to the main menu.

12
Transmit Data To upload transaction data to the host PC.
There are three ways to transmit the data:
via RS-232 or Infrared or standard IrDA.
Note: terminal COM port settings should
match the host PC settings.
Download Settings To download the menus and form
prompts for the data collection process.
The settings should be configured in the
Application Generator,then downloaded
to the terminal. The Application
Generator allows to define menus and
data input forms. For detail operation,
please refer to the Application Generator's
Operation Guide.
4.4Build your own application module
There are three software tools available for developing
application programs.
1. The Application Generator
2. The “BASIC”Compiler
3. The “C”Compiler
For more information, please contact CipherLab USA or
Syntech Information Co., Ltd.

5. Operations
Batteries must be fresh and properly loaded before start
operation.
5.1 Keypad operations
The keypad of CPT-720 Portable Terminal consists of 32
rubber keys and one power switch. The functions of some
special keys are as follows:
BS Back Space.
If pressed down longer than one
second, a clearcode will be sent.
Shift Shift (toggle key)
When it is in shift mode, an up-
arrow icon will be shown in the
screen. Alphabet input will be small
letter and F8 can be used to turn
on/off the display back-lit. Also the
F6 and F7 can be used to adjust the
display contrast.
Alpha The toggle key for Alphabet /
Numeral input.
When the system is in alpha-mode, a
small icon will be shown on the
right most side of the display.
ESC Escape.
Usually this key is to exit current
operation.
POWER Power On/Off.
To prevent a faulty push, it needs
about 1.5 sec continuous pressing to
turn On/Off the power.

14
5.2 Application mode
This is the default operation mode when turning on the
power. The operation depends on the application module.
Please refer to section 4.4.
5.3 System mode
When pressing the 7, 9and POWER keys simultaneously, the
system will enter the System Mode with which provides the
following services:
1. Memory
Size Information Includes the SRAM (Data memory)
size, extended memory size (Smart-
Media Card) and FLASH (Program
memory) size in kilobytes.
Initialize To initialize the data memory
(RAM). Note that the contents of the
data space will be wiped out after
memory initialization.
Test To test the data memory. For 256
KB SRAM, it takes about 15
seconds to finish the test. Note that
the contents of the data space will be
wiped out too after memory test.
2. Setting
Clock To set new date and time.
Backlit To set the intensity of LCD back-
light and the duration for staying on.
Default:High intensity, the lights go
off after 20 seconds.

15
Speed To set CPU running speed. There
are five speeds available:
Full speed, 1/2 speed, 1/4 speed, 1/8
speed and 1/16 speed; which need
about 39mA, 22mA, 12mA, 7mA
and 5mA,respectively,during
normal operation (without scanning
or data transmission). If high-speed
operation isnot required, selecting
low CPU speed will save battery
power.
Default: Full speed
Auto Off Set time threshold for auto power-
off when no operation is taking
place during that specified period. If
this value is set to zero, this function
will be disabled.
Default: 10 minutes
Power On There are two possible selections:
Program Resume, which starts from
the program being used during the
last session before the last power-off;
and Program Restart, which starts
with a new program.
Default: Program Resume
3. Reader
Reading test To test the reading performance of
the scanner. Following are the
default enabled symbologies:
Code 39
Industrial 25
