10 1.2.2 Supported Softw are The software used with this terminal can be div ided into two categories: the system 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 formatter Window s Driver These drivers are necessary for the Windows to run on IT-2000. Download to F -ROM driv e (D: ). File nam e Storage location Description VGA_C.DRV VGA_NC.DRV MASK ROM driv e (E: ) Display drivers PENMOUSE.
12 Development Tool Libraries All the libraries of Windows are provided either as Dy namic L ink Library (DLL ) or as Visual BASIC Custom Control (VBX). To use these libraries, download first to a directory in F -ROM drive (D: ). The files, * .LIB and * .
13 1.3 Precautions If reading the internal clock with I NT21h the significant data should include and be limited to the seconds digits. On thi s terminal the tim e is read directly from the RTC so that the correct time can be attained at any mom ent, even during extended continuous use.
14 If an L B1 event (low main battery voltage) occurs, the alarm buzzer starts sounding and sy stem operation is suspended about 10 minutes later. I f the alarm buzzer starts sounding, terminate the current operation as soon as possible and recharge the main battery .
15 The backlight is turned off by m eans of the ABO (Auto Backlight OFF ) function. However, it is turned off 1.3 seconds after the setup time. This is because the sy stem has 1.3 seconds of monitoring tim e before the internal timer is started. During the process of loading Windows after boot-up, do not press the Power switch.

18 2.1.3 Driv e Configuration The drive configuration differs for each m odel as described in the following table: RAM disk Driv e A: [Read and Write] This drive is prepared for use after the RAM disk size is specified from the System Menu. The contents of this RA M disk will not be erased through a boot process or by pressing the RESET sw itch.
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/resume process and boot process operated by m eans of the Power switch and RESET switch, as shown in the following diagram. Fi g. 2.
20 The following table summ arizes the power-on processes provided for this term inal. System Menu boot process Alway s exec utes CONF IG.SYS and AUTOEXEC.BAT loca ted in drive (C:) for starting up the MS- DOS. Application boot process Searches for CONFI G.
21 2.2.2 Pow er ON Process Overv iew The ON process is provided to make the sy stem ready for use (ON state). The actual process varies depending on the settings at that point in time and the last OF F factor (the cause of the OF F action).
22 System Menu Boot Process Press the RES ET 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 “Sys tem Menu Boot Process” 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 switch 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 This terminal has the Auto Power O N function which automatically starts the system . This A uto Power ON function can operate in one of the following three way s: Auto Pow er ON function (only aff ects the resume process) activated by alarm The system power can be turned on (resumed) at the specified tim e by means of an alarm .
25 2.2.3 Pow er OFF Process Overv iew Turns off the system power. However, the power to all the dev ices is not turned off and some 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 OFF factors refer to various causes that make the sy stem enter the OFF state (suspend state), as follows: OFF factor Description Suspend Power switch System operation can be suspended by holding down the Power switch for more than a second.
27 2.2.4 Battery Voltage Monitoring Process This terminal uses a main battery (lithium- ion battery pack) for driving the m ain unit, and a primary sub-battery (lithium battery ) and a secondary sub-battery (lithium- vanadium battery ) for backup.
28 Low Voltage Level The IT-2000 continuously monitors the voltage of the m ain battery, the prim ary sub-battery , and the SRAM card battery. This allow s an application program to determine through the sy stem library if the voltage of each battery reaches a warning level.
29 Main Battery Voltage Monitoring If the m ain battery voltage reaches L B1, the system issues a warning buzzer. I f this warning buzzer sounds, either start recharging the battery or replace it w ith a fully charged battery as soon as possible.
30 Sub-batter y Voltage Monitoring The sub - batteries are used for s y ste m backup while the m ain batter y is being replaced. The sub- batteries consists of two units: the pri m ar y sub - batter y (button - t y pe lithiu m batter y ) and secondary sub - batter y (button - t y pe lithiu m - vanadiu m batter y ).
31 2.2.5 Low Consumption Current Process This terminal has the APM BIOS installed to provide a low-power consumption capability . It works in com bination with POWER.
32 A uto Pow er OFF Function (A PO) This function automatically shifts the system to the OF F 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.
33 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).
34 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 replacement procedure m ay result in a loss of data.
35 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, even 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.

Touch the correct position. Key Operation Function 1 key Adjusts the touch panel calibration starting from the beginning.
61 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 com munication". A dedicated 9- pin DSUB-8-pin cross-ty pe cable (DT-9689AX) is required to connect both the terminals.
62 Note: When the cable comes off w hile the comm unication takes place: If the connection cable is accidentally unplugged while comm unication between the IT-2000 and PC is taking place, a communication error results and com munication is interrupted.
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). I t is not allowed to use the function. If the file transm ission between IT-2000s is needed, F LINK utility may be used (refer to Chapter 3.
64 When the "Normal End" message is displayed on the I T-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 comm unication, file reception will be interrupted.
65 3.11 FLINK Command Function Files can be transferred by infrared comm unication (IR). This can be implem ented either as PC-to- HT (AT-com patible machine to IT- 2000) communication or as HT- to-HT (between two I T-2000 terminals) com munication.
66 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.
67 Note: If the “CL R” key is pressed during file transfer, transfer will be interrupted. It will take about 10 seconds for comm unication to completely stop.

76 4. MS-DOS 4.1 Ov erview In general, if a personal com puter is booted-up with a floppy disk in the driv e, 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:).
77 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 (m aintenance program).
78 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 mentioned 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 manual or appropriate technical documents.
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 mem ory space for UMB if the EM S memor y is t o be used. Therefore, alw ays speci fy NOUMB w hen using the EMS.
80 Example of A UTOEXEC.BA T The following example shows a ty pical AUTO EXEC.BAT script. Since this example assum es that the sy stem is booted from either 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.
81 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.
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.
83 CONFI G.SYS which resides on the drive C. Howev er, CARDID.EXE cannot be registered as a device driv er at a card boot. If this CARDID.EXE is registered as a device driv er, two drives may be enabled concurrent ly if M S-DOS executes CONF IG.SYS. In addi tion, if ENDATA.
84 5. MS-Window s 5.1 Ov erview The MASK ROM driv e (E:) of this terminals has MS-Windows installed in it. However, MS-Window s cannot be booted directly from this MASK ROM drive. This is because MS-Windows will overwrite som e of the INI files at start up.
85 5.2 Installation of MS-Window s As explained on the previous page, it is necessary to move (copy ) some files onto the write-perm it drive before booting MS-Windows. This section will describe this copy operation The following is an example of m anually installing necessary files so that the user can determine the contents.
86 Note: The contents of the latest version of E: WINDOWS L OCAL may be released as SDK. I f this is the case, use the files in SDK instead of those stored in E: WINDOWS LOC AL. 5.2.2 A pplication Installation For this term inal it is recommended to initiate the application program at the same time MS-Windows is started.
87 6. Key board Controller 6.1 Ov erview This terminal is equipped with a sub- CPU dedicated to controlling the keyboard, touch panel, backlight, and various sensors.
88 6.2 Key board Control The keyboard control of I T-2000 is compatible with the I BM PC /AT. The key board controller senses if a key has been pressed and sends a MAK E or BREAK code to the m ain CPU.
89 Secondary code Basically a sy stem scan code is assigned to each key , however, for some key s, different codes will be assigned depending on the Fn key . Code Table The following diagram shows the relationship between the keyboard key s and primary codes.
90 6.3 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 6.4 Sensor Control This terminal has the following three ty pes of sensors installed to serve as dedicated devices for handy term inal. Sensor Pu rpose of Use Temperature sensor Detects the temperature inside the main unit. This result will be used to automatically compensate the LCD brightness.
92 6.5 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 types 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 1A B C disabled Backlight ON sta te 2 2 3 or 4 *1 -- - Ignore Ignore 2A B C disabled Backlight O FF st at e 1 --- 3 or 4 .
