5 Preface The IT- 2000 Technical Reference Manual (hereinafter referred to as this document) is provided to assist the user in developing programs to run on the Casio I T-2000 (hereinafter referred to as this terminal or I T-2000 or HT in this m anual).
6 1. Ov erv iew 1.1 Features of Sy stem 1.1.1 Dev elopment Concept The IT-2000 is a data collection term inal for business use. After y ears of refinement Casio Computer Co., L td. has developed its hand- held type term inals so that they yield high speed and a high functionality in com parison to general personal computers.
7 PC card slot conforms to PCMCIA Release 2.1 supporting various PC cards. Im plements I rDA 1.1 protocol for high-speed infrared com munication. System menu m akes it easy to m aintain the IT- 2000 and install user application programs.
8 1.1.5 Model Name The following IT-2000s of MS- DOS version will be available. For price of each m odel, please consult with y our local Casio representative.
9 1.2 Sy stem Configuration 1.2.1 Hardw are Block Diagram CPU i486GX 1 Power switch A/D converter Buffer DRAM F LASH ROM (DI NOR) MASK ROM Lithium -ion battery Secondary sub- battery Primary sub- battery IrD A Driver/Receiver RS-232C driver PC card slot IrD A 1.
10 1.2.2 Supported Softw are The software used with this terminal can be div ided into two categories: the sy stem software that includes the BIOS, OS, and dev ice drivers and the user software such as the developm ent tools.
11 TFORMAT.E XE Basic drive (C:) F-ROM drive form atter Utilities For inform ation about the utilities refer to Chapter 8 "Utility". File nam e Storage location Description CAL.EXE SDK Calendar utility CALC.EXE SDK Calculator utility CLOCK.EXE SDK Clock utility CHKBATT .
12 1.3 Precautions I f reading the internal clock with I NT21h the significant data should include and be li m ited to the seconds digits. On thi s ter m inal the ti m e is read di rectl y fro m the RTC so that the correct ti m e can be attained at an y m o m ent, even during extended continuous use.
13 This system will not execute an alarm indication for an L B2 event (low sub-battery voltage) or LB3 ev ent (low SRAM card battery v oltage). Therefore, the application program side m ust acquire the alarm status v ia the system library and display an appropriate alarm message.
14 Do not input “^P” from the DOS prompt. I f it is input, “^P” requests DOS to redirect console output to printer. However, the IT-2000 does not hav e the printer being installed, it will enter into wait mode. For m ore information about the sy stem library refer to Chapter 7.
15 2. Basic Softw are 2.1 Ov erv iew 2.1.1 Softw are Configuration The following diagram shows the software configuration of the IT- 2000. F i g . 2 . 1 Note: The P enMouse driver and K eypad driv er cannot co-exist on the sy stem.
16 2.1.2 Memory Map The mem ory m ap of the IT- 2000 is as follows. F i g . 2 . 2 Extended Memory ROM BI OS NAND DISK BI OS/VGA BIOS Memory Mapped Disk I/F 100000h 0F0000h 0E0000h 0DC000h 0D8000h 0C80.
17 2.1.3 Dri v e Configuration The drive configuration differs for each m odel as described in the following: If F-ROM drive is supported RAM disk Dri v e A: [Read and Write] This drive is prepared for use after the RAM disk size is specified from the S y ste m Menu.
18 If F-ROM drive is not supported RAM disk Dri v e A: [Read and Write] This drive is readied for use after the RAM disk size is specified from the S y ste m Menu. The contents of this RAM disk will not be erased through a boot process or b y pressing the RESET switch.
19 2.2 Basic Sy stem Operation 2.2.1 Ov erv iew Basic operation of this system on the terminal consists of the suspend/resum e process and boot process operated by m eans of the Power switch and RESET switch, as shown in the following diagram. F i g .
20 The following table summ arizes the power-on processes prov ided for this terminal. System Menu boot process Alway s executes CONF IG.SYS and AUTOEXEC.BAT locat ed in drive (C:) for starting up the MS- DOS. Application boot process Searches for CONFI G.
21 2.2.2 Po w e r O N Process O v er v iew The ON process is provided to m ake the s y ste m read y for use (ON state). The actual process varies depending on the settings at that point in ti m e and the last O FF factor (the cause of the O FF action).
22 Syste m Menu Boot Process P ressing the RESET switch sets the drive C: as the current driv e, and MS - DOS is loaded from that drive. As a result, the S y ste m Menu that includes the m aintenance progra m will be initiated (refer to “S y ste m Menu Boot P rocess” on this page).
23 Note: The RESE T switch can be used not onl y for initiating the S y ste m Menu but also as the forced restart witch when the user application progra m under develop m ent hangs. Howev er, note that if the RESET switch is pressed while the disk is being written to, the data m a y be corrupted.
24 Auto Po w er ON f unction (only affects the resu m e process) activated by alarm The s y ste m power can be turned on (resu m ed) at the specified ti m e b y m eans of an alar m . However, this will not function if the next start - up m ethod is set to the boot process in the s y stem librar y .
25 2.2.3 Pow er OFF Process Overv iew Turns off the system power. Howev er, the power to all the devices is not turned off and som e can be used for storing the information required for the next resum e operation. This process is called the suspend process and the state of the system while off is called the suspend state.
26 OFF Factors The O FF factors refer to various causes that m ake the s y ste m enter the O FF state (suspend state), as follows: O FF factor Description Suspend P ower switch S y ste m operation can be suspended b y holding down the P ower switch for m ore than a second.
27 Note: Hold down the Po wer switch for more than one second until the power is off. This is done to prevent the power from accidentally being turned off by the user. In addition, key input will not be enabled for approximately one second after the Power switch has been pressed.
28 2.2.4 Battery Voltage Monitoring Process This terminal uses a main battery (lithium-ion battery pack) for driving the main unit, and a prim ary 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 sy stem library.
29 Low Voltage Level The IT-2000 continuously m onitors the voltage of the main battery , the primary sub-battery , and the SRAM card battery. This allow s an application program to determ ine through the system library if the voltage of each battery reaches a warning level.
30 Main Battery Voltage Monitoring If the m ain battery v oltage reaches LB1, the sy stem issues a warning buzzer. If this warning buzzer sounds, either start recharging the battery or replace it w ith a fully charged battery as soon as possible.
31 For inform ation about the method used to replace the m ain battery refer to Chapter 2.2.6 “ How to Replace or Recharge Batteries”. Sub-battery Voltage Monitoring The sub-batteries are used for sy stem backup w hile the main battery is being replaced.
32 A cquiring Po w er Status through Batter y Status A cquisition Utility With the batter y status acquisition utilit y the user can be advised of the current re m aining voltage of the m ain batter y , sub - batter y status, or connector status in real ti m e.
33 2.2.5 Low Consumption Current Process This terminal has (1) the APM BIOS installed to provide a low-power consumption capability . It works in com bination with POWER.
34 A uto Powe r 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 interv al has been set to one minute by default.
35 DOZE/RUN Transit Function On this terminal the sy stem 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).
36 Note: If the power m anagement function is disabled by the system library , the Auto Power OFF function (APO ) is also disabled. This is because both the power managem ent function and Auto P ower OFF function use the same activity processing routine.
37 2.2.6 How to Replace or Recharge Batteries Replacement of Batt eries The method used to replace the m ain battery, sub- battery , and SRAM card battery are explained here. Failure to observ e the correct battery replacem ent procedure may result in a loss of data.
38 Note: The SRAM card is supplied power by the main battery when it is installed in the main unit. This means that the SRAM card can be used norm ally as long as it is in the slot, ev en if the voltage of the card battery is zero. In this case, however, the data on the SRAM card will be lost when the card is remov ed from the main unit slot.

61 3.8 A uto Pow er OFF Setup Function Sets the time- out period of the auto power off function (APO) (refer to Chapter 2.2.3 “P ower OF F Process"). This time-out period is the interv al between when no key entry or no entry on the touch panel is made and when the power of sy stem is shut off automatically .
62 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 perform ing this calibration adjustment. Fi g.
63 Note: If an mark does not disappear and the arrow does not m ove 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 Function 1 key Adjusts the touch panel calibration starting from the beginning.
64 3.10 YMODEM Utility Function Used to achieve a file transfer via the COM cable. Comm unication can be established either between an AT-com patible machine (PC) and an IT- 2000 (main unit), referred to as "PC-to- HT comm unication". A dedicated 9-pin DSUB- 8-pin cross-ty pe cable (DT-9689AX) is required to connect both the terminals.
65 Note: When the cable comes off wh ile the comm unication takes place: If the connection cable is accidentally unplugged while com munication between the I T-2000 and PC is taking place, a comm unication error results and comm unication is interrupted.
66 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 av ailable). It is not allowed to use the function. If the file transm ission between IT-2000s is needed, F L INK utility may be used (refer to Chapter 3.
67 When the "Normal End" message is display ed on the IT- 2000 side, file reception has been completed. F or information about the copy destination directory refer to the following table. If the “CL R” key is pressed during com munication, file reception will be interrupted.
68 3.11 FLINK Command Function Files can be transferred by infrared communication (IR). This can be im plemented either as PC-t o- HT (AT-com patible machine to I T-2000) comm unication or as HT-t o-HT (between two I T-2000 terminals) com munication. To perform PC-to-HT comm unication an I/O Box and a PC-side comm unication utility "L MDOS.
69 Note: I f the identical file na m e exists on the reception side, this co mm and overwrites the existing file. At this ti m e, the s y ste m does not unconditionall y overwrite the existing file but creates a te m porary file on the reception - side disk and atte m pts the overwrite after file trans m ission has been co m peted.
70 Note: If the “CL R” key is pressed during file transfer, transfer will be interrupted. I t will take about 10 seconds for comm unication to completely stop.
71 3.12 Sy stem Date/Time Setup Function This is used to set (modify ) the date and time of the built- in timer in the IT- 2000 unit. Fi g. 3.15 Operation Enter in the following order: y ear -> m onth -> day - > hour -> m inute. Press a numeric key and the corresponding number will appear in the cursor position.
72 3.13 Command Prompt Function This is the MS DOS comm and prompt screen. An appropriate DOS com mand can be inputted through the keypad. This DOS com mand prom pt is the result of calling COM MAND.COM as a child process from the system menu. Consequently , if the EXIT command is entered, operation returns to the sy stem menu.
73 3.14 RA M Disk Size Change Function This screen is used to set the RAM D ISK size (capacity). The setting will becom e valid after the system has rebooted. Fi g. 3.17 Operation Setting up the RAM disk Adjust the RAM disk size with the “8” and “2” keys.

76 Key Operation Function 2 or 8 key Selects the objective item (drive selection screen). 0 key Does not perform formatting (form atting start screen). 1 key Starts formatting (form atting start screen). . (decimal) key Toggles YES and NO options of formatting.
77 3.16 Sy stem Initialization Function Sets all the system setups to their defaults. Fi g. 3.21 Operation The following table shows the available key operations. Key Operation F unction 0 key Does not initialize the system . 1 key Initializes the sy stem.
78 3.17 Passw ord Entry Function When "F IL E TRANSFER" or " MAINTENANCE" is selected for the first time after the system menu is initiated, the operator is requested to enter a password. Fig. 3.22 Operation With the key pad enter " syst em" (lowercase lett er), then press the “RET” key .
79 4. MS-DOS 4.1 Ov erv iew If a personal com puter is booted-up with a floppy disk in the drive, first an attempt will be m ade 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:).
80 As described above, if the sy stem power is turned on without an application installed (i.e. the conditions just after purchase), the CONFI G.SYS and AUTOEXEC.BAT files locating on the basic drive will be executed autom atically. This inevitably initiates the System Menu (maintenance program).
81 4.2 How to Write CONFIG.SYS and A UTOEXEC.BA T This section explains how to write the CONF IG.SYS and AUTOEXEC.BAT files m entioned in the previous section. A basic explanation of the CONF IG.SYS and AUTOEXEC.BAT is not given here. For further inform ation about these files refer to the MS-DOS m anual or appropriate technical documents.
82 Note: 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 m emory space for UMB if the EMS me mory is to be used. Therefore, al way s specify NOUMB when using the EMS.
83 Example of A UTOEXEC.BAT The following example shows a ty pical AUTOEX EC.BAT script. Since this example assum es that the sy stem is booted from eit her the RAM disk or the NAND F -ROM driv e, it is necessary to partially m odify it if booting up from the ATA card.
84 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. F or this terminal the boot operation looks the sam e as this case.
85 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.
86 CONFI G.SYS which resides on the drive C. Howe ver, CARDID.EXE cannot be registered as a device driv er at a card boot. If this CARDID.EXE is registered as a dev ice driver, two drives m ay be enabled concurrent ly i f MS-DOS execut es CONF IG.SYS.
87 5. Key board Controller 5.1 Ov erv iew This terminal is equipped with a sub- CPU dedicated to controlling the keyboard, touch panel, backlight, and various sensors.
88 5.2 Key board Control The keyboard control of this term inal is compatible with the I BM PC/AT. The keyboard controller senses if a key has been pressed and s ends a MAKE or BREAK code to the m ain CPU.
89 Secondary code Basically a sy stem scan code is assigned to each key, howev er, for some key s, different codes will be assigned depending on the Fn key . Code Table The following diagram shows the relationship between the key board keys and prim ary codes.
90 5.3 Touch Panel Control Function The keyboard controller has incorporated a program for acquiring the touch coordinates of the touch panel. This program com pensates these acquired coordinates with the values obtained through calibration so that correct coordinate values can be calculated.
91 5.4 Sensor Control This terminal has the following three ty pes of sensors installed to serve as dedicated devices for handy term inal. Sensor type Purpose of Use Temperature sensor Detects the temperature inside the main unit. This result will be used to automatically compensate the L CD brightness.
92 5.5 Backlight Control This terminal has incorporated two ty pes of automatic backlight control functions: ABO (Auto Backlight OFF ) and ABC (Auto Backlight Control).
93 Transition of Backlight Control Methods The concept of ABC lies in automating user operations. Howev er, automatic control depends on the illumination sensor. I t cannot be perfect because various ty pes of light, sunlight or room light for example, m ay be incident to the sensor.
94 Press F7 key ABO time- up ABC Enable ABC Disable Becomes dark Becomes light 1 ABC disabled Backlight ON state 2 2 3 or 4 *1 -- - Ignore I gnore 2 ABC disabled Backlight OFF state 1 --- 3 or 4 *1 --.
95 6. Driv ers 6.1 Ov erv iew The following drivers are supplied for this term inal. Install them as required for operation. Name File nam e Purpose System driver SYSDRV.SYS Driver required to operate the sy stem. This driver m ust be installed. Clock control driver TIME.
96 6.2 Sy stem Driv er 6.2.1 Function The system driver (SYSDRV. SYS) must be installed because it executes critical processes in this terminal. The sy stem driver m ainly performs the following processes. LB1 monitoring and warning Monitors the main battery conditions and sounds a warning buzzer if an L B1 event is detected.
97 6.3 Clock Control Driv er 6.3.1 Function This driver adjusts the system time on this term inal. This driver must be installed. On a general PC a timer interrupt occurs every 55 msec to update the clock tick counter, which is one of the BIOS sy stem v ariables, and the clock overflow counter.
98 6.3.2 Startup Method This driver is loaded by defining the DEVICE statem ent in the CONFI G.SYS file. TIME.SYS is stored in the basic drive (C:). Format DEVICE=C: TIME.SYS Start option None Note: TIME.SYS must be loaded im mediately after P OWER.EXE.
99 6.4 Key pad Driv er/Hardw are Window Manager 6.4.1 Function The keypad driv er ( KEYPAD.EXE ) is used to add the key pad function to the system . Application programs can use the key pad by calling the key p ad driver functions v ia the keypad library (refer to Chapter 7.
100 6.4.2 Startup Method Format HWWMAN [Option] KEYPAD [Option] Start option /R Cancels the residence. To make each driver resident in the m ain mem ory, m ake the following specification at the DOS prompt. Alway s install the hardware window m anager first.
101 6.5 PenMouse Driver 6.5.1 Overv iew The PenMouse driver (PENMOUSE.DRV) simulates the operation of the mouse driv er (INT33h) specific to the personal computer using inputs receiv ed from the touch panel.
102 6.5.2 Startup Method The PenMouse driver is supplied as an SDK. Before use, copy it to the F- ROM drive (D:) or RAM disk (A:). To load the PenMouse driver, make the following specification at the DOS prom pt. Format: PENMOUSE [Option] Start option: /R Cancels the residence.

153 7.6.3 Key pad Library Overv iew This library is used to m ake an entry through the keypad or acquire the coordinates on the screen being touched. Note about the Libraries The key input library is supplied on one of the four m odels suitable for the application program developed by the user.
154 Key pad Driver As internal process, this library calls the key pad driver (KEYPAD.EXE). The relation among this library, the key pad driver and BIOS is as follow. Fig. 7.13 Transition of Key pad State The following shows the transition of key pad when it is operated.
155 Fi g. 7.15 Key code ASCII keycodes can be acquired with the input function of this library . Scanning codes cannot be acquired. A cceptance timing of key code A key input is perform ed by touching the appropriate area on the keypad.
156 A cquisition of coordinates The coordinates of a position touched can be acquired. However, while the key pad is being displayed, it is only possible to acquire a set of coordinates if an area outside the key pad is touched. In this case the coordinates will be recorded together with the following coordinate status.
157 Input acceptance mode There are two modes for accepting key inputs, as follows: DOWN acceptance mode In this m ode the area touched in the pen-down action will change to reverse v ideo and the acquired keycode will be stored in the buffer. This reverse- video area is restored to norm al when the pen is lifted.
158 Clearing the buffer If the key buffer clear comm and is issued while the key pad is being touched, processing for the current operation will also be canceled. For exam ple, a reverse-v ideo display will be restored to normal, and no new key inputs will be permitted until the pen (or user' s finger) is remov ed from the panel.
159 About the buff er clear Consider the appropriate timing to clear the buffer. I f the buffer clear comm and is issued after the down coordinates are acquired, acquisition of the up coordinates is hampered.
160 List of Input Functions P age F unction Description 160 K EY_CheckE xist Checks if the ke y pad driver is installed 161 K EY_Read Acquires a ke y code or coordinates 162 K EY_Scan Checks if a ke y code or coordinates are in the buffer. 163 K EY_Clear Clears the ke y code and coordinate buffers.
161 Readout from Key Buffer Acquires a key code or coordinates w hich have been acquired from the key buffer. I f the buffer contains neither a key code nor coordinates, NO_DATA will be returned. However, coordinate values can be returned only if the coordinates input mode is set to “enable”.
162 Checking Key Buffer Cont ent Checks if a key code or coordinates are in the buffer. I f either is present, the key code or coordinates will be returned. The buffer remains uncleared. Use the KEY_Read function to load the data. However, the coordinates will not be returned if the coordinates input mode is set to “disable”.
163 Key Buffer Clear Clears both the system buffer and key BIOS buffer. I f coordinate input by pen touch is continued, coordinate values selected until the pen is lifted will be ignored. F urthermore, any operation in progress on the pad will be canceled at that point.
164 A cquisition of Number of Key pad Being Display ed Acquires the number of the currently display ed keypad. SYNTAX int KEY_GetPadState(void); INP U T None OUTPUT KDC_PAD OFF (0) Non-display KDC_PADENG (1) Being display ed EXAMPL E #include "padlib.
