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:

Ÿ Program download Ÿ Update kernel Ÿ Test & Calibrate

For detail operations, please refer to section 5.4.

4.2 System module

The system module provides the following system services

Ÿ Memory Ÿ Setting Ÿ Reader Ÿ Battery Ÿ Test Ÿ Download Ÿ Version

For detail operations, please refer to section 5.3.

4.3 Application 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:

Ÿ Execute Ÿ Clear Data Ÿ Transmit Data Ÿ Download Settings

The arrow keys can be used to select the menu item, and execute it by pressing the ENTER key. The function and meaning of each item are as follows:

Execute Start the data collection process.

A new screen appears after Execute is 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, No must be selected when asked to confirm the operation or by pressing the ESC key to go back to the main menu.

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.

4.4 Build 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 clear code will be sent.

Shift Shift (toggle key)

When it is in shift mode, an uparrow 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.

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, 9 and 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 (SmartMedia 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.

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 is not 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 Interleave 25 Codabar Code 93

Code 128 UPCE UPCE with ADDON 2 UPCE with ADDON 5 EAN8 EAN8 with ADDON 2 EAN8 with ADDON 5 EAN13 EAN13 with ADDON 2 EAN13 with ADDON 5

Other symbologies, must be enabled through programming.

4. Battery

Main Show voltage of the main battery

power. If the main battery voltage is low, a battery icon (power-low indicator) will be shown on the LCD screen. The available power will be less than 25% of fresh batteries, The terminal will continue to work normally for a short period of time.

Backup Show voltage of the backup battery.

5. Test

Buzzer To test the buzzer with different

Frequency/Duration. Press ENTER key to start the test, then press any key to stop the test.

LCD & LED To test LCD display and LED

indicator. Press ENTER key to start the test, then press any key to stop the test.

Ø Check if the RS-232 cable is plugged tightly,

then,

Ø Check if host communication parameters (COM

port, baud rate, data bits, parity, stop bit) match the CPT-720 Portable Terminal's.

e) Cannot download application program from the host

to the CPT-720 Portable Terminal or vice versa, via IrDA port.

Ø Check if the IrDA transceiver tightly connected

to host's COM port, then

Ø Check if host communication parameters (COM

port, baud rate, data bits, parity, stop bit) matched portable's.

properly positioned within the reading range: (5 to 100cm, 30 degree solid angle) of the IrDA transceiver.

f) Keypad does not work properly,

Ø Turn off the power then press the 7, 9 and

POWER keys simultaneously to enter the kernel

mode operation.

Ø From the system menu, select the Test and then

its sub-item KBD.

Ø Perform the key-in test. Ø If problem persists, call for service.

g) Scanner does not scan,

Ø Check if symbologies used are enabled, or Ø Check if battery-low indicator is shown on the

LCD display. If yes, change the batteries.

Ø If problem persists, call for service.

h) Abnormal responses,

Ø Open the battery holder and re-load the batteries. Ø Enter system menu by pressing 7, 9 and POWER

keys simultaneously.
