Chapter 1. Introduction

The WDT2200 is a programmable and flexible data collection device that can be utilized in a variety

of data acquisition applications. It can be used as a portable data entry device or as a programmable

dedicated computer that receives and runs application programs downloaded from a host computer.

The WDT2200 is equipped with a 16-bit INTEL 8088 compatible microprocessor, and has 256K of

user updateable FLASH ROM that includes a rich set of DOS functions and device drivers for

application development, including bar code decoding, display, keypad, communications, and a real

time clock/calendar.

The WDT2200 can be purchased with 2.5MB of on-board RAM. The RAM memory is powered by

the rechargeable main Li-ion battery pack and a backup Lithium button cell battery, which retains

the data stored in RAM and powers the real time calendar/clock when the main battery is drained.

The WDT2200 has a 128x64 pixel backlit graphic LCD display, an integral 27-key keypad, a built-

in laser or CCD bar code scanner module and an RS-232 serial port for data communication with a

host PC.

1.1 Programming

The WDT2200 system kernel includes three basic modules: 1. Device driver, 2 File manager and

3.DOS manager. The WDT2200 terminal can be programmed using an E-PROM resident

application program called FormCaching, a Windows-based, high-level application generator

AppGen, Microsoft C, Borland C, Turbo C, Turbo Pascal and IBM PC macro assembler. The

ROM based firmware of the terminal provides emulated MS/DOS function calls. The programmer

can design the application programs by calling those functions just like in a DOS environment.

The calling and parameter passing conventions are compatible to that of MS/DOS and the

programs are in the EXE format. Programming details are included in the WDT2200

programming manual in this binder.

Page 4 of 41

______________________________________________________

The intelligence level of the terminal is determined by the configuration of the FormCaching

application or the downloaded program generated by AppGen or supported language compiler.

Once the program has been started up, the terminal operates as a stand-alone unit, storing

transaction data in the RAM disk area or linked to a host/personal computer.

1.2 Subsystems

The following describes several subsystems and related I/O interface functions, the DOS manager

and file manager functions. Detailed calling process is explained in the Programming Reference

Guide included in this binder.

1.2.1 Keypad Subsystem

The keypad subsystem scans the key matrix, converts the scan code to its associated key value and

stores the value in the keyboard input buffer for program utilization. The table below shows

hexadecimal values assigned to each key.

1.2.2 Display Subsystem

The WDT2200 display subsystem supports a character oriented 8-line by 20-character or 4-line by

16-character LCD display. The origin (0,0) is always at the top-left hand corner. This subsystem

provides the program interface functions to display characters, set cursor position, get cursor position

and clear screen display.

Page 5 of 41

______________________________________________________

1.2.3 Serial Port Subsystem

The WDT2200 terminal has an RS-232 serial port for data communication. The communication

subsystem consists of point-to-point protocol for general processing and multi-point protocol for

network processing. The WDT2200 also supports a built-in Kermit server for point-to-point

communication.

1.2.4 Real Time Clock Subsystem

This subsystem allows users to set and obtain system date and time from the Real Time Clock

Integrated Circuit (IC) in the WDT2200.

1.2.5 Bar Code Input Port

The WDT2200 has a built-in barcode decoder. The terminal reads bar code labels through an

integrated laser scanner module, pen type module.

1.3 Diagnostics and Power-On-Test

The system diagnostic routines exercise the ROM validity check, test the RAM, system parameters,

the keypad, the real time clock, the RS-232 port, LCD and scanner port. The power-on-test is a

subset of the system diagnosis that only includes the ROM validity check, system parameter check

sum test, and back-up battery level check.

______________________________________________________

Chapter 2. System Software Organization

The WDT2200 system software is organized into two modules: the kernel module and the

application module (see diagram below).

2.1 Application Module

Although applications run on the WDT2200 are classified into resident and transient categories, the

WDT2200 operation can’t decipher the difference between them. The only difference is the location

of the executable files. For resident applications, the Job Scheduling EXEC "jumps" to the entry

point in the EPROM and begins execution. For transient applications EXEC "loads" the executable

file from the RAM file into the RAM memory and then begins execution.

2.2 Kernel Module

The WDT2200 kernel provides basic system services. The kernel module includes the DOS Manager,

File Manager, COM Manager and several interrupt service routines.

DOS Manager The DOS manager emulates most MS DOS function calls to control WDT2200

peripherals and files.

FILE Manager The File manager implements a DOS-like file subsystem to support essential file

operations.

Page 7 of 41

______________________________________________________

COM Manager The COM manager controls the communication link between the WDT2200 and

the host through a RS232 serial port.

LOADER The function of the loader is identical to that of the MSDOS loader except for the

memory allocation/de-allocation scheme being simplified. The loader's operations

are:

1. read .exe header

2. find enough memory for .exe

3. read binary into RAM

4. relocation based on RAM allocation

5. set up all registers

6. jump to the entry point

LCD Manager The LCD manager handles the cursor positioning and graphic pattern display.

Two character pattern fonts are supported. The WDT2200 can support both 6x8

font (20 column by 8 lines) and 8x16 font(16 column by 4 line).

EXEC The EXEC is the job scheduler. It manages top-level operation flow of the

WDT2200 system. The EXEC program is analogous to the COMMAND.COM

program in MS DOS-based machines.

2.3 Operation Flow

The EXEC program controls the WDT2200. When the portable terminal is powered up, EXEC

performs the power-on-test (POT). EXEC proceeds to verify if the WDT2200 should make a warm

or cold booting. A warm boot resets the system without clearing any RAM program or data files.

Device configurations preserve the same values as they had before the warm boot. On the other hand,

a cold boot will clear the RAM and initialize the WDT2200 to default values.

The WDT2200 is always testing its main and backup batteries. The LCD will display a warning

message when the test fails.

Power on Test Test failure message

Main battery test "WARNING MAIN BATTERY LOW"

Backup battery test "WARNING LITHIUM BATTERY LOW"

When the main battery is low, a warning message will be displayed on the LCD when THE

WDT2200 is power on. For THE WDT2200, it can automatically detect battery status, a warning

sign will be display on battery icon on the upper side of LCD.

During the start-up process, EXEC also initializes the WDT2200 barcode scanner and RS232

communication port, and creates all dynamic data structures; e.g. keypad queue and COM buffer.

Page 8 of 41

______________________________________________________

Once the initialization procedure has been completed, EXEC checks if a supervisor menu has been

requested. The supervisor menu can be requested if the operator holds down both [CMD] and []

keys while powering up the WDT2200.

NOTE: 1) Cold start, will clear all data stored in the RAM and reinitialize the portable

terminal to system default.

2) There are two system flags, “Start” flag and “Save NOT OK” flag, which will be

verified each time the unit is turned on.

3) When the “Start” flag verification fails, it indicates that there is probably a

defective RAM chip or that the backup battery power is low. A data back up and

hardware diagnostics are recommended in these cases.

4) The “Save NOT OK” flag is used to check if the previous turn-off process was

made normally or not. The system will not return to the last turn-off point if the

“System Resume” is set to On when this flag verification fails.

A program downloaded to the WDT2200 may be automatically executed each time the portable

terminal is turned on. In order for the program to be auto-ran, it must be downloaded to THE

WDT2200 with the name AUTOEXEC.EXE. When the WDT2200 is turned on, the system will

scan the file directory and execute the program, otherwise it will enter a mode of operation called

the READY mode. In this mode, the WDT2200 will standby for keypad-entered commands, or

commands from the Host PC.

Chapter 3. OPERATING MODES

3.1 Keyboard Modes --- Using THE WDT2200’s keyboard

The keypad of THE WDT2200 consists of 27 rubber keys, the power key is used to switch on/off the unit and

other 26 keys are used to control the unit and key in data. Use of the keyboard is categorized to three modes:

normal mode, command mode, and alpha(betic) mode. All keys except the power key may produce a

sound (tone) when pressed. Keys in the upper four rows are larger to facilitate data entry.

When the unit is off, pressing the power key will turn on the unit. On the other hand, when the

unit is on, it is necessary to press and hold down the power key for about one second in order to

turn the unit off.

[CMD] Pressing the [CMD] key sets the keyboard to Command mode. However, pressing and holding

down the [CMD] key for two seconds in Ready mode will access the User mode. In User mode,

users can invoke system commands by menu selection.

______________________________________________________

3.2 WDT2200 Modes of Operation

There are three modes of operation in the WDT2200:

a. Ready Mode

b. User Mode

c. Supervisor Mode

3.2.1 Ready Mode

The Ready mode is the default operating mode. In the Ready mode, the WDT2200 is configured as a

portable programmable device, and is capable of receiving files (Download) from or transmitting

files (Upload) to a Host PC. Data files or recorded information collected from the WDT2200 are

uploaded to the host whenever the host program is ready to receive the collected data. Some

applications may also require prepared data files (e.g. database information). These data files are

loaded to the WDT2200 in the same manner as application programs are downloaded. The

WDT2200 carries out upload and download operations through its built-in RS232 port. The operator

can later select one of the executable applications to run in the portable terminal via the keypad or

host command sequence.

After the Warm Start, the WDT2200 enters the Ready mode and shows the Ready mode screen as

shown left. The first line indicates the model code and BIOS firmware version number. The second

line shows the size of the installed RAM. The third line shows the prompt, ">" which indicates that

the terminal passed the Power-on-test and is in the Ready mode of operation.

Ready Mode User mode menu

Press and Hold down [cmd]

Key for two second

Press [CMD] then [Alpha]

3.2.2 User Mode

The User Mode allows the operator to issue commands to the WDT2200. Pressing and holding down

the [CMD] key for two seconds while in the Ready Mode will invoke the User Mode (see figure

below). There are eight commands: 1.RUN, 2.TER, 3 COM, 4.DIR, 5. ERA, 6.TYP, 7.CPY, and

8.SET. Select the corresponding number, 1 through 8, or press [] and [] to move the cursor then

press [ENT] to select and execute the desired command to the WDT2200. Pressing [CMD] then the

[Alpha] key will return the system to the Ready Mode.

Page 12 of 41

______________________________________________________

User Mode Commands:

Command Usage

RUN Runs the selected executable program

TER Terminal emulation mode or FormCaching operation

COM Kermit server mode

DIR Display RAM disk file directory

ERA Delete a file from RAM disk

TYP Dump the content of a file to the LCD

CPY Copy data from a device/file to another device/file

SET Set real time clock, scanner type or power-on logo

3.2.2.1 RUN

After a program is downloaded to the handheld unit, the user may invoke the

RUN command and press [→

→→

→] key to display the executable files stored in

memory, then press [ENT] to run the program. Pressing [CMD] then [Alpha]

and then pressing any key will return the WDT2200 to the User Mode menu.

3.2.2.2 TER

The TER command puts the WDT2200 in either Terminal Emulation operation or FormCaching

operation.

Terminal Emulation Operation. When EXEC transfers control to this EPROM-resident

application program, the WDT2200 operates as a dumb ASCII terminal while exchanging data with

a Host computer. Data input from scanning bar code labels or key entry will be sent to the portable

terminal’s RS-232 port. In order to carry out a successful file transfer, communication parameter

settings such as baud rate, data bits, parity, stop bits and flow control, must match the setting at the

Host end. Data received from the serial port is displayed on the LCD screen.

The functionality of the WDT2200 in terminal mode depends on the format configured in the

Terminal Control Table. The WDT2200 is either configured as free format processing or forms

based processing. The WDT2200 examines the "data buffer" and determines if host data transfer is

required. If a terminating condition exists by the reception of a terminating character, the WDT2200

outputs the buffer to its RS232 port. Data transfer between the host machine and the WDT2200 is

primarily controlled by the terminating conditions specified in the Terminal Control Table.

In the terminal application, the program further distinguishes character mode communication from

block mode communication. Character mode communication dictates that the WDT2200 send every

character, one at a time, to the host. Normally, character mode communication uses None protocol,

otherwise there will be an overwhelming protocol overhead. The input characters may come from the

keypad or barcode scanner, whichever comes first. Data characters sent over from the host system

< RUN PROGRAM >

Filename:

NULL

Page 13 of 41

______________________________________________________

will always be displayed on the LCD screen. Host control commands, which have a special

command header (ESC), will not be displayed on the LCD. The host commands are interpreted by

the WDT2200 as they are received.

Block mode applications perform similar functions to character mode, except that the input

characters will not be sent to the host one character at a time. Instead the WDT2200 holds the data in

its internal buffer until a termination character is received. Specifying the linepage, lineterm, and

pageterm parameters in the terminal control table programs the termination character. The

WDT2200 allows two termination characters at most.

FormCaching Operation. When EXEC transfers control to this EPROM-resident application

program, it allows the user to create a data entry application program by simply specifying field

prompt, type, length, input method and delimiter, etc. without having to write a comprehensive

application program. FormCaching is enabled or disabled while the WDT2200 is in the Supervisor

mode of operation.

3.2.2.3 COM

The COM command activates the WDT2200 Kermit server. Pressing [CMD] then [Alpha] returns

the WDT2200 to the User Mode of operation. The following list shows the available Kermit

commands in the Host/PC:

Command Description

SEND program

Sends a file from the Host/PC to the WDT2200 and

stores it in the WDT2200's RAM disk.

GET data

Gets a collected data file from the WDT2200 to the Host/PC disk.

REMOTE DIR

Lists WDT2200 RAM disk file directory.

REMOTE DEL filename

Deletes a program or data file from the WDT2200 RAM disk.

BYE

Exit Kermit Mode

Before making use of the Kermit server, switch the WDT2200 to the Supervisor mode and set the

WDT2200 communication parameters to match the host/PC system. See Section 3.2.3.1 Device

Configuration.

3.2.2.8 SET

The SET command allows the user to set system date-time, select type of bar

code scanner, assign laser module scanning method, enable double

verification and specify whether to enable the power-on logo. Select the

corresponding number, 1 through 4, to invoke a function. Pressing the [CMD]

and then the [Alpha] key returns the portable terminal to the User Mode

menu.

3.2.2.8.1 DATE & TIME Set System Clock/Calendar

By selecting “1.DATE & TIME” in the SET menu, you can set the WDT2200 date and time. The

date and time can be used as the time stamp to be appended to an input data record by an application

program. The second line shows the current system date in the format YYYY/MM/DD

(year/month/day). For instance, 1998/01/01 indicates that date is January 1, 1996. If you want to

reset the system date to August 31, 1997, then enter [1],[9],[9],[7],[0],[8],[3],[1] or press the [ENT]

key to skip the system date setting.

The third line shows the current time. The setting method is similar to setting the date. The time is

expressed in the 24-hour format using HH:MM:SS (hours:minutes:seconds).

3.2.2.8.2 SCANNER

SCANNER The bar code input interface of the WDT2200 is compatible with all major bar

code scanners that are available in the market including wand, CCD and laser

diode scanners. Use the [] key to toggle among ENABLE and DISABLE,

then press [ENT].

LASER TRIG MODE : The user can select whether the pen is activate to read barcode label

by one trigger/one scan or by flash scan. If it is set to NORMAL, the laser beam

will be emitted to scan a barcode and will stop upon reading the barcode

successfully. The user needs to release the trigger key and then press again to

scan next label. If it is set to FLASH, the user just presses the trigger and then

releases it, then the scanner will automatically scan the barcode. When it

successfully reads a barcode, the scanner will continue to emit a laser beam to

read the next label. The user can press trigger again to stop automatic scanning.

LASER AIM When WDT2200 is equipped with SE1200LR engine, user can use this setting to

activate aim beam before starting scanning barcode. It will be helpful for user to

focus on a target barcode label. Use the [] key to toggle between ENABLE

and DISABLE, then press [ENT].

VERIFICATION Poor label quality can cause decoding errors. You can enable this function to

let the WDT2200 double verify bar code input. When it is set to ENABLE, the

WDT2200 reads barcode labels twice, comparing the data before sending it.
