  • Page 3: Chapter 1. Introduction

    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.

  • Page 4: Subsystems

    & 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: Serial Port 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.

    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.
  • Page 8 “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.

  • Page 9: 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.

  • Page 10: Normal Mode

    NORMAL mode 3.1.1 Keyboard of the WDT2200 is initialized to normal mode after powered on. In normal mode, the cursor is a block sign and the keyboard is mainly used to input numeric data and use F1-F4 four function-keys. The keypad layout of available keys in normal mode is shown on right picture.

  • Page 11: Wdt2200 Modes Of Operation

    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.
  • Page 12 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.
  • Page 13 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.
