Resumen del manual
Contrast Adjustment The contrast of the liquid crystal display automatically compensates for temperature changes. The user can adjust the offset value (refer to Chapter 5 “Keyboard Controller”) for the automatically adjusted contrast in the following ways. . Press the 8 key after the Fn key to increase the contrast offset one step. . Press the 9 key after the Fn key to decrease the contrast offset one step. . Call the system library to increase/decrease the contrast offset. 40 2.3.2 EL Backlight Overview This terminal has the following functions to control the backlight. For more information refer to Chapter 5, “Keyboard Controller”. . Manual Backlight ON/OFF function . Auto Backlight OFF function (ABO) . Auto Backlight Control function (ABC) Manual Backlight ON/OFF Function The backlight can be turned on and off with the following methods. . Press the 7 key after the Fn key to turn on or off the backlight. . Call the system library to turn on or off the backlight. Auto Backlight OFF Function This function automatically turns off the backlight when no key or touch panel input has been occurred in the specified period of time. The time interval until the backlight is automatically turned off can be set with the System Menu or the system library. Auto Backlight Control Function This function detects the intensity of ambient light and automatically turns on or off the backlight accordingly. This function is set to off by default, however, it can be set to on using the System Menu or system library. For more information about the system library refer to Chapter 7.6.2 “ System Library”. 41 2.3.3 Touch Panel Hardware Configuration Method : Analog type touch panel Resolution : 192 x 384 dots Software Function To enable application programs to acquire touch panel coordinates, the following two pieces of software are provided: . PENMOUSE.COM With this PENMOUSE.COM application programs can acquire touch panel input through the mouse I/F. (refer to Chapter 6.5 “PenMouse Driver”.) . KEYPAD.EXE With this keypad driver application programs can perform character input through the touch panel. However, it cannot be used concurrently with PENMOUSE.COM. (refer to Chapter 6.4 “Keypad Driver / Hardware Window Manager”.) 42 2.3.4 Disk Types of Disk Type Drive name Capacity RAM disk A 0 to 1920 Kbytes Basic drive C 768 Kbytes F-ROM disk D 0, 4, 8, 12, 16 or 24 Mbytes PC card G or F SRAM card, ATA card Note: The drive name of the PC card varies for each model. For more information refer to Chapter 2.1.3 “Drive Configuration”. 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. The contents of the RAM disk are not affected by pressing the RESET switch either. Since this RAM disk permits the use of INT13h, it can be used as the built-in fixed disk. Its drive name is A. Note: Since the RAM disk shares part of the main memory installed in the main unit, a large-size RAM disk may affect the operation of application programs. Basic Drive Part of the DINOR FLASH ROM is used as the basic drive. It cannot be written to. Disk capacity : 768 KB Since the basic drive supports the INT13h (Read Only) interrupt, it can be used as the built-in fixed drive. Its drive name is C. 43 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. For information about the formatting method refer to Chapter 3 “System Menu”. In this process the System Menu will call TFORMAT.EXE from drive (C:) to format the F-ROM drive. For more information about the TFORMAT.EXE operation refer to Appendix A TFORMAT. Since this F-ROM drive supports the INT13h interrupt, it can be used as the built-in fixed drive. Its drive name is D. PC Card Drive If either an SRAM card or ATA F-ROM card is inserted in the PC card slot, it can be used as the drive G (Drive F for models without the F-ROM drive). If the ATA F-ROM card is inserted in the card slot, the system can boot up according to the CONFIG.SYS/AUTOEXEC.BAT files included on this card. This start-up method is called "card boot". For more information about card boot refer to Chapter 4.3 “Card Boot”. 44 2.3.5 Serial Communication Available Interfaces Port I/O Address Name Uses Remark COM1 3F8h-3FFh 8-pin serial I/F Connection with a barcode reader or PC COM2 2F8h-2FFh 14-pin serial I/F Connection with an expansion I/F device Can be switched via the system library.
