Page 13: Precautions
1.3 Precautions If reading the internal clock with INT21h the significant data should include and be limited to the seconds digits. On this terminal the time is read directly from the RTC so that the correct time can be attained at any moment, even during extended continuous use. As a result the 1/100 of a second digit is ignored.
Page 14 If an LB1 event (low main battery voltage) occurs, the alarm buzzer starts sounding and system operation is suspended about 10 minutes later. If the alarm buzzer starts sounding, terminate the current operation as soon as possible and recharge the main battery. This system will not execute an alarm indication to be displayed on the LCD screen for an LB2 event (low sub-battery voltage) or LB3 event (low SRAM card battery voltage).
Page 15 The backlight is turned off by means of the ABO (Auto Backlight OFF) function. However, it is turned off 1.3 seconds after the setup time. This is because the system has 1.3 seconds of monitoring time before the internal timer is started. During the process of loading Windows after boot-up, do not press the Power switch.

Page 18: Drive Configuration
2.1.3 Drive Configuration The drive configuration differs for each model as described in the following table: Drive A: RAM disk [Read and Write] This drive is prepared for use after the RAM disk size is specified from the System Menu. The contents of this RAM disk will not be erased through a boot process or by pressing the RESET switch.
Page 19: Basic System Operation
2.2 Basic System Operation 2.2.1 Overview Basic operation of this system on the terminal consists of the suspend/resume process and boot process operated by means of the Power switch and RESET switch, as shown in the following diagram. OFF STATE OFF EVENT OFF Process System Menu...
Page 20 The following table summarizes the power-on processes provided for this terminal. System Menu boot Always executes CONFIG.SYS and AUTOEXEC.BAT located process in drive (C:) for starting up the MS-DOS. Application boot process Searches for CONFIG.SYS and AUTOEXEC.BAT prepared by the user and starts up MS-DOS from the drive where they are located.
Page 21: Power On Process
2.2.2 Power ON Process Overview The ON process is provided to make the system ready for use (ON state). The actual process varies depending on the settings at that point in time and the last OFF factor (the cause of the OFF action). ON factors: Pressing the Power switch Pressing the RESET switch...
Page 22 System Menu Boot Process Press the RESET switch to set the drive C as the current drive, and load MS-DOS from that drive. As a result, the System Menu that includes the maintenance program will be initiated (refer to “System Menu Boot Process” on this page). Resume Process This process restores the conditions that existed before the power was most recently turned off.
Page 23 Note: The RESET switch can be used not only for initiating the System Menu but also as the forced restart switch when the user application program under development hangs. However, note that if the RESET switch is pressed while the disk is being written to, the data may be corrupted. Therefore, the RESET switch should be pressed only while the power is off.
Page 24 This terminal has the Auto Power ON function which automatically starts the system. This Auto Power ON function can operate in one of the following three ways: Auto Power ON function (only affects the resume process) activated by alarm The system power can be turned on (resumed) at the specified time by means of an alarm. However, this will not function if the next start-up method is set to the boot process in the system library.
Page 25: Power Off Process
2.2.3 Power OFF Process Overview Turns off the system power. However, the power to all the devices is not turned off and some can be used for storing the information required for the next resume operation. This process is called the suspend process and the state of the system while off is called the suspend state.
Page 26 OFF Factors The OFF factors refer to various causes that make the system enter the OFF state (suspend state), as follows: OFF factor Power switch System operation can be suspended by holding down the Power switch for more than a second. (see note) Auto Power OFF System operation automatically shifts to the suspend state (APO)
Page 27: Battery Voltage Monitoring Process
2.2.4 Battery Voltage Monitoring Process This terminal uses a main battery (lithium-ion battery pack) for driving the main unit, and a primary sub-battery (lithium battery) and a secondary sub-battery (lithium-vanadium battery) for backup. Application programs can acquire the status of these batteries through the APM BIOS or system library.
Page 28 Low Voltage Level The IT-2000 continuously monitors the voltage of the main battery, the primary sub-battery, and the SRAM card battery. This allows an application program to determine through the system library if the voltage of each battery reaches a warning level. The following table summarizes the low battery voltage warning levels, which application programs can acquire through the system library.
Page 29 Main Battery Voltage Monitoring If the main battery voltage reaches LB1, the system issues a warning buzzer. If this warning buzzer sounds, either start recharging the battery or replace it with a fully charged battery as soon as possible. If one of these measures is not taken within ten minutes, the system will forcibly turn off the power for safety.
Page 30 Sub-battery Voltage Monitoring The sub-batteries are used for system backup while the main battery is being replaced. The sub- batteries consists of two units: the primary sub-battery (button-type lithium battery) and secondary sub-battery (button-type lithium-vanadium battery). The secondary sub-battery is recharged by the voltage of the main battery.
Page 31: Low Consumption Current Process
2.2.5 Low Consumption Current Process This terminal has the APM BIOS installed to provide a low-power consumption capability. It works in combination with POWER.EXE from Microsoft Corporation. The low-power consumption capability is further enhanced by the use of unique power management functions, including Auto Power OFF (APO) function, Auto Backlight OFF (ABO) function, and DOZE/RUN transit function.
Page 32 Auto Power OFF Function (APO) This function automatically shifts the system to the OFF state (suspend state) if no event has taken place for a specified period of time from the touch panel, the keyboard, COM1, or a file. This time interval has been set to one minute by default. It can be modified using the System Menu or system library.
Page 33 DOZE/RUN Transit Function On this terminal the system will reduce the clock speed of the built-in CPU if no activity (access to the touch panel, keys, COM1, or file) has occurred for a specified period of time (four seconds). The state in which the CPU clock speed has been reduced is called the "DOZE state" and the state in which the CPU is operating at full speed is called the "RUN state".
Page 34: How To Replace Or Recharge Batteries
2.2.6 How to Replace or Recharge Batteries Replacement of Batteries The method used to replace the main battery, sub-battery, and SRAM card battery are explained here Failure to observe the correct battery replacement procedure may result in a loss of data. Always observe the following steps in battery replacement.
Page 35 In this case, however, the data on the SRAM card will be lost when the card is removed from the main unit slot. Since the Casio SRAM card is provided with two batteries, the data will not be lost a short while even if one of them is removed. However, it is recommended that the SRAM card battery be replaced only after making a backup of the data to avoid accidental loss.

RAM Disk Part of the main RAM can be assigned on the RAM disk using System Menu. The contents of the RAM disk will not be erased if the power switch is turned on and off, since they are backed-up by the main battery and the sub-batteries.
Page 41 F-ROM Drive The F-ROM drive is supported as a disk for which both read and write operations are possible (only for models with the F-ROM drive). Various disk capacities are supported for each model: Disk capacity: 0 (models without F-ROM), 4M, 8M, 12M, 16M or 24 MB. To format the F-ROM drive use the System Menu.
Page 42: Serial Communication
2.3.5 Serial Communication Available Interfaces Port I/O Address COM1 3F8h-3FFh COM2 2F8h-2FFh COM3 3E8h-3EFh COM4 2E8h-2EFh COM1 This is a COM port for RS-232C communication. This port can be used after turning on the power to the 8-pin serial I/F via the system library. The 8-pin serial I/F is located on the side panel of the main unit.
Page 43 COM2 Either the 14-pin serial I/F or IrDA 1.0 can be assigned to this COM2 port depending on the system library setup. Both the 14-pin serial I/F and IrDA 1.0 can be used as a normal RS-232C interface. By default, the COM2 channel is not assigned to either device. Therefore, always use the system library to designate either the 14-pin serial I/F or IrDA, then turn on the power.

2.3.6 PC Card Hardware Overview Standard Register compatibility Slot Power supply Card lock switch Recommended PC Cards Type SRAM card ATA Flash ROM card How to Format SRAM Card and ATA F-ROM Card To format, call FORMAT.COM in the basic drive (C:). Then, in the DOS prompt screen that appears, execute the following command to format the SRAM card or ATA F-ROM card.
Page 45 Card Lock Switch The IT-2000 has a card lock switch to prevent accidental removal of the card. Any card can be made usable only after it has been inserted in the slot and the switch has been locked properly. However, since some types of cards do not allow this card lock switch to be closed, a library routine to disable this switch is supported.
Page 46: Clock Timer
2.3.7 Clock Timer Clock BIOS 00h to 07h of the INT1Ah function is compatible with the IBM PC/AT. Since INT1Ah can be called in the C language, an alarm operation using the clock can be set with the system library. Alarm If an alarm operation is set using the INT1Ah or system library, it is possible to cause an INT4Ah interrupt at the specified time to issue the alarm.
Page 47: Buzzer
2.3.8 Buzzer This terminal is provided with a buzzer function that is compatible, via an appropriate interface, with the IBM PC. The application side can sound this buzzer by controlling the I/O port assigned to 61h. It is also possible to modify the sound frequency by controlling channel 2 of the timer. For information about the method used to modify the frequency refer to the hardware manual of the PC/AT compatible machine.

3.9 Touch Panel Calibration Function Adjusts the calibration of touch panel. If an inconsistency is noted between the target position and the position actually touched on the touch panel, correct it by performing this calibration adjustment. Operation Adjustment of the calibration : First make sure that the arrow points to the center of this When the buzzer sounds, release the stylus from the touch panel.
Page 60 Note: If an mark does not disappear and the arrow does not move to the next position even if the mark has been touched by the stylus, an incorrect position was likely touched. Touch the correct position. Key Operation 1 key Adjusts the touch panel calibration starting from the beginning.
Page 61: Ymodem Utility
3.10 YMODEM Utility Function Used to achieve a file transfer via the COM cable. Communication can be established either between an AT-compatible machine (PC) and an IT-2000 (main unit), referred to as "PC-to-HT communication". A dedicated 9-pin DSUB-8-pin cross-type cable (DT-9689AX) is required to connect both the terminals. This utility does not have functions to allow communication between HT and HT.
Page 62 Note: When the cable comes off while the communication takes place: If the connection cable is accidentally unplugged while communication between the IT-2000 and PC is taking place, a communication error results and communication is interrupted. In this case the communication software on the PC will display an error message and interrupt transmission/reception, however, some data may remain in the transmission buffer.
Page 63 Operations (1) SEND FILE TO HT (one file transmission from IT-2000 to IT-2000) This function may be available in future (as of now, not available). It is not allowed to use the function. If the file transmission between IT-2000s is needed, FLINK utility may be used (refer to Chapter 3.11 “FLINK Command”.).
Page 64 When the "Normal End" message is displayed on the IT-2000 side, file reception has been completed. For information about the copy destination directory refer to the following table. If the “CLR” key is pressed during communication, file reception will be interrupted. It will take about 10 seconds for communication to completely stop.
Page 65: Flink Command
3.11 FLINK Command Function Files can be transferred by infrared communication (IR). This can be implemented either as PC-to- HT (AT-compatible machine to IT-2000) communication or as HT-to-HT (between two IT-2000 terminals) communication. To perform PC-to-HT communication an I/O Box for IT-2000 and a PC-side communication utility "LMWIN.EXE"...
Page 66 Note: If the identical file name exists on the reception side, this command overwrites the existing file. At this time, the system does not unconditionally overwrite the existing file but creates a temporary file on the reception-side disk and attempts the overwrite after file transmission has been competed. This protects file data even if transmission of the file fails.
Page 67 Note: If the “CLR” key is pressed during file transfer, transfer will be interrupted. It will take about 10 seconds for communication to completely stop. REMOTE SERVER (remote server mode ) The remote server mode is used by the system which assigns the right of issuing a transmission request to the partner side and enters the wait state for a request from the partner.
Page 68: System Date/Time Setup
3.12 System Date/Time Setup Function This is used to set (modify) the date and time of the built-in timer in the IT-2000 unit. Operation Enter in the following order: year -> month -> day -> hour -> minute. Press a numeric key and the corresponding number will appear in the cursor position.
Page 69: Command Prompt
3.13 Command Prompt Function This is the MS DOS command prompt screen. An appropriate DOS command can be inputted through the keypad. This DOS command prompt is the result of calling COMMAND.COM as a child process from the system menu. Consequently, if the EXIT command is entered, operation returns to the system menu. Fig.

3.17 Password Entry Function When "FILE TRANSFER" or "MAINTENANCE" is selected for the first time after the system menu is initiated, the operator is requested to enter a password. Operation With the keypad enter "system" (lowercase letter), then press the “RET” key. If the “CLR” key is pressed without entering a character, the password entry operation will be canceled.
Page 76: Chapter 4 Ms-Dos
4. MS-DOS 4.1 Overview In general, if a personal computer is booted-up with a floppy disk in the drive, first an attempt will be made to read MS-DOS from the floppy disk, and if a copy of MS-DOS does not reside on the floppy it is loaded from the hard disk (C:).
Page 77 As described above, if the system power is turned on without an application installed (i.e. the conditions just after purchase), the CONFIG.SYS and AUTOEXEC.BAT files locating on the basic drive will be executed automatically. This inevitably initiates the System Menu (maintenance program).
Page 78: How To Write Config.sys And Autoexec.bat
4.2 How to Write CONFIG.SYS and AUTOEXEC.BAT This section explains how to write the CONFIG.SYS and AUTOEXEC.BAT files mentioned in the previous section. A basic explanation of the CONFIG.SYS and AUTOEXEC.BAT is not given here. For further information about these files refer to the MS-DOS manual or appropriate technical documents.
Page 79 (1) DOS=HIGH,NOUMB This specifies that the main part of DOS is to be loaded in the HMA and, consequently, the UMB (Upper Memory Block) is not used. This terminal does not support a memory space for UMB if the EMS memory is to be used. Therefore, always specify NOUMB when using the EMS.
Page 80 Example of AUTOEXEC.BAT The following example shows a typical AUTOEXEC.BAT script. Since this example assumes that the system is booted from either the RAM disk or the NAND F-ROM drive, it is necessary to partially modify it if booting up from the ATA card. For information about booting from the ATA card refer to Chapter 4.3 "Card Boot".
Page 81: Card Boot
4.3 Card Boot Basically the "card boot" operation boots MS-DOS from the ATA card, just like it is booted from a floppy disk. For this terminal the boot operation looks the same as this case. However, this terminal uses a boot process greatly different from a general card boot so that the MS-DOS in the drive C is always loaded, in such a way that MS-DOS not residing in the card is booted.
Page 82 the drive G, which is currently enabled, will be disabled. This problem arises from the fact that the hardware conditions established by initialization with CARDID.EXE are lost since access to the drive F was executed by means of specific codes included in the BIOS.
Page 83 CONFIG.SYS which resides on the drive C. However, CARDID.EXE cannot be registered as a device driver at a card boot. If this CARDID.EXE is registered as a device driver, two drives may be enabled concurrently if MS-DOS executes CONFIG.SYS. In addition, if ENDATA.COM is called with the INSTALL command, the drive G is enabled exclusively.
Page 84: Chapter 5 Ms-Windows
5. MS-Windows 5.1 Overview The MASK ROM drive (E:) of this terminals has MS-Windows installed in it. However, MS-Windows cannot be booted directly from this MASK ROM drive. This is because MS-Windows will overwrite some of the INI files at start up. However, since all files including the INI files are initially located in the MASK ROM drive, they cannot be overwritten, therefore an error will result.
Page 85: Installation Of Ms-Windows
5.2 Installation of MS-Windows As explained on the previous page, it is necessary to move (copy) some files onto the write-permit drive before booting MS-Windows. This section will describe this copy operation The following is an example of manually installing necessary files so that the user can determine the contents. A utility program (WINST.EXE) can be used to reduce the work load.
Page 86: Application Installation
Note: The contents of the latest version of E: the case, use the files in SDK instead of those stored in E: 5.2.2 Application Installation For this terminal it is recommended to initiate the application program at the same time MS-Windows is started.

6. Keyboard Controller 6.1 Overview This terminal is equipped with a sub-CPU dedicated to controlling the keyboard, touch panel, backlight, and various sensors. This chapter describes major tasks assigned to this sub-CPU. Main CPU LCD Brightness El Backlight Command Sub-CPU Data Buzzer Volume...
Page 88: Keyboard Control
6.2 Keyboard Control The keyboard control of IT-2000 is compatible with the IBM PC/AT. The keyboard controller senses if a key has been pressed and sends a MAKE or BREAK code to the main CPU. Application Program Function Process BIOS Hardware Interrupt Process Sub-CPU Keyboard...
Page 89 Secondary code Basically a system scan code is assigned to each key, however, for some keys, different codes will be assigned depending on the Fn key. Code Table The following diagram shows the relationship between the keyboard keys and primary codes. Fn key The Fn key is used to generate a system scanning code for the function key if it is pressed together with a numeric key.
Page 90: Touch Panel Control Function
6.3 Touch Panel Control Function The keyboard controller has incorporated a program for acquiring the touch coordinates of the touch panel. This program compensates these acquired coordinates with the values obtained through calibration so that correct coordinate values can be calculated. The calculated coordinates will be passed to a ROM-resident program called PEN BIOS when mouse interrupt occurs.
Page 91: Sensor Control
6.4 Sensor Control This terminal has the following three types of sensors installed to serve as dedicated devices for handy terminal. Sensor Temperature sensor Illumination sensor Remaining battery voltage sensor Purpose of Use Detects the temperature inside the main unit. This result will be used to automatically compensate the LCD brightness.
Page 92: Backlight Control
6.5 Backlight Control This terminal has incorporated two types of automatic backlight control functions: ABO (Auto Backlight OFF) and ABC (Auto Backlight Control). The ABO function is used to turn off the backlight if no key or touch panel input has been made for a given period of time, and the ABC function is used to automatically turn on and off the backlight depending on the intensity of the ambient light.
Page 93 Transition of Backlight Control Methods The concept of ABC lies in automating user operations. However, automatic control depends on the illumination sensor. It cannot be perfect because various types of light, sunlight or room light for example, may be incident to the sensor. Consequently, this requires manual ON/OFF control even if under ABC control.

Page 196: Keypad Library
8.6.3 Keypad Library Overview The keypad library (Padctrl.vbx) is used to perform key input with the keyboard that is graphically displayed in the screen. This library can be made available when it is registered as a control on the application program. This control can be set up according to the specific properties including the modification of keypad, acquiring and modifying the key acceptance mode, etc.
Page 197 Input acceptance mode There are two acceptance modes for key input. Down acceptance mode When the pen is down on the keypad, the touched area changes to reverse video, and the corresponding keycode is generated. The reverse video area will return to normal when the pen is up.

When "PADCTRL.VBX"is displayed in the "Installled"column, click on the "OK" button. Fig. 8.12 Fig. 8.13...
Page 199 (3) A new button is added in the lower section of the toolbox. However, if other controls have been registered already, the left hand-side figure will include more buttons. Fig. 8.14 With the above procedure registration of the keypad to AppStadio is completed. Explained next is the method of registering the keypad in the dialog.
Page 200 (2) As the following dialog is displayed, select "Dialog" and click on the "OK" button. With the above operation the dialog is added as a resource. (3) Next, click on the keypad button (as shown in the lower right of the left hand-side figure) of the tool box to the pressed-in position and click inside the dialog.
Page 201 (4) Modify the keypad size so that all keys can appear within the screen. (5) Subsequently, layout the necessary controls such as the edit box, etc. on the dialog. As the screen size of this system is 384 x 192 (pixels), layout the controls so they can be accommodated in this range.
Page 202 Note: The keypad library will transmit characters to the control which is focused at. Accordingly, if the focus is placed in other control than the edit box, click on the edit box or move the focus over the edit box with the program that is using SetFocus(), etc. How to use with VB application In order to develop an application program that utilizes the keypad library with the VB, it is necessary to register the keypad library to Visual BASIC.

Page 284: Windows Installation Utility
9.10 Windows Installation Utility Overview MS-Windows has been installed on the MASK ROM drive (E:). However, MS-Windows cannot be booted directly from the MASK ROM drive. This is because MS-Windows will overwrite some of the INI files at start up. However, since all the files including the INI files are initially located in the MASK ROM drive, they cannot be overwritten, therefore an error will result.
Page 285 Operation at Menu Startup WINST.EXE can run either on the IT-2000 or on a personal computer. However, since the IT-2000 is not provided with an arrow key to move the bar-type cursor, use the following key operations. Move cursor up Move cursor down Accept Cancel...

If, for example, the application program uses the OBR library, make the following settings for WINST.INF: UpdateDrivers=yes and UseOBR=yes. Then place OBRLIB.DLL in the same directory as WINST.EXE/WINST.INF.
Page 289 MD G: WINDOWS COPY E: WINDOWS LOCAL G: If the IrDA interface is used to load COMM.DRV with the following procedure. COPY E: WINDOWS COMM.DRV G: COMM.DRV must be stored in the same directory as WINST.EXE. Therefore, in the above example it is loaded onto the root directory.
Page 290 Example of execution on the IT-2000 Directly set up the environment by executing WINST.EXE on the IT-2000. If WINST.EXE and the other essential files are stored in the PC card, the card can be used for installation. Prepare the objective installation files, including WINST.EXE and WINST.INF, in the ATA card.

Page 295: Acquisition Of Suspend/Resume Event And Power Status
APPENDIX C: Acquisition of Suspend/Resume Event and Power Status Overview Suspend/Resume event is notified by multiplex interrupt (INT2Fh). If any event such as power ON/OFF occurs, consequently the interrupt (INT2Fh) will occur. An application can acquire the event by catching the interrupt. Since the interrupt INT2Fh is multiplex interrupt, application must reset values in all the registers to the previous values after catching the interrupt and then return the control to the old-vector.
Page 296 Acquisition of Power Status Application can acquire current power status by calling APM BIOS through the interrupt INT15h. The following power statuses can be acquired by using the method. AC line status Battery status Battery flag Remaining battery life - percentage of charge Remaining battery life - time unites The functions detailed below will acquire the power statuses stated above.
Page 297 DX = Remaining battery life - time unit bit 15 = 0 : Time unit is in second. 1 : Time unit is in minute bits 14 to 0 = value for second or minutes 0 to 7FFFh : Valid value for second or minute : Unknown If function unsuccessful: Carry = 1...
