0.7 STATIC ELECTRICITY PRECAUTIONS

Before removing the board from its anti-static bag, read this section about static electricity precautions.
Static electricity is a constant danger to computer systems. The charge that can build up in your body may be
more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic
precautions whenever you use or handle computer components. Although areas with humid climates are much
less prone to static build-up, it is always best to safeguard against accidents may result in expensive repairs. The
following measures should generally be sufficient to protect your equipment from static discharge:

• Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded
wrist strap).

• When unpacking and handling the board or other system component, place all materials on an antic static
surface.

• Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom
of every board.

1.1 INTRODUCTION

The AR-B1462 is a disk size industrial grade CPU card that has been designed to withstand continuous operation
in harsh environments. The total on-board memory for the AR-B1462 can be configured from 1MB to 128MB by
using all 72-pin type DRAM SIMM devices.

The 8 layers PCB CPU card is equipped with a IDE HDD interface, a floppy disk drive adapter, 1 parallel port, 4
serial ports and a watchdog timer. Its dimensions are as compact as 146mmX203mm. It highly condensed
features make it an ideal cost/performance solution for high-end commercial and industrial applications where CPU
speeding and mean time between failure is critical.

The AR-B1462 provides 2 bus interfaces, ISA bus and PC/104 compatible expansion bus. Based on the PC/104
expansion bus, you could easy install thousands of PC/104 module from hundreds venders around the world. You
could also directly connect the power supply to the AR-B1462 on-board power connector in standalone
applications.

A watchdog timer has a software programmable time-out interval, is also provided on this CPU card. It ensures
that the system does not hang-up if a program can not execute normally.

A super I/O chip (SMC37C669) is embedded in the AR-B1462 card. It combines functions of a floppy disk drive
adapter, a hard disk drive (IDE) adapter, four serial (with 16C550 UART) adapters and 1 parallel adapter. The I/O
port configurations can be done by set the BIOS setup program.

As an UART, the chip supports serial to parallel conversion on data characters received from a peripheral device
or a MODEM, and parallel to serial conversion on data character received from the CPU. The UART includes a
programmable baud rate generator, complete MODEM control capability and a processor interrupt system. As a
parallel port, the SMC37C669 provides the user with a fully bi-directional parallel centronics-type printer interface.

The special device is the AR-B1462 provides one audio connector, the sound system is built-in 16bit PnP sound
blaster with DOS and Windows drivers. In the same time the AR-B1462 provides network connectors that are 10M
bps NE2000 compatible. We designed the connectors for easily setup.

The super VGA controller supports CRT color monitor, STN, Dual-Scan, TFT, monochrome and colored panels. It
can be connected to create a compact video solution for the industrial environment. And provides the touch screen
header on the serial port 4 for multiple function.

Note: Just the AR-B1462A supported the audio function and supported 2MB on-board VRAM. The AR-B1462 only

supported 1MB on-board VRAM.

2. SYSTEM CONTROLLER

This chapter describes the major structure of the AR-B1462 CPU board. The following topics are covered:

l DMA Controller
l Keyboard Controller
l Interrupt Controller
l Real-Time Clock and Non-Volatile RAM
l Timer
l Serial Port
l Parallel Port

2.1 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the AR-B1462 board. Each controller is a four­channel DMA device that will generate the memory addresses and control signals necessary to transfer
information directly between a peripheral device and memory. This allows high speeding information transfer with less
CPU intervention. The two DMA controllers are internally cascaded to provide four DMA channels for transfers to
8-bit peripherals (DMA1) and three channels for transfers to 16-bit peripherals (DMA2). DMA2 channel 0 provides
the cascade interconnection between the two DMA devices, thereby maintaining IBM PC/AT compatibility.

Following is the system information of DMA channels:

DMA Controller 1 DMA Controller 2

Channel 0: Spare Channel 4: Cascade for controller 1
Channel 1: IBM SDLC Channel 5: Spare
Channel 2: Diskette adapter Channel 6: Spare
Channel 3: Spare Channel 7: Spare

Table 2-1 DMA Channel Controller

2.2 KEYBOARD CONTROLLER

The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives
serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data
in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the
system to poll its status register to determine when data is available.

Data can be written to the keyboard by writing data to the output buffer of the keyboard controller.

Each byte of data is sent to the keyboard controller in series with an odd parity bit automatically inserted. The
keyboard controller is required to acknowledge all data transmissions. Therefore, another byte of data will not be
sent to keyboard controller until acknowledgment is received for the previous byte sent. The “output buffer full”
interruption may be used for both send and receive routines.

2-1

AR-B1462 User¡¦s Guide

2.3 INTERRUPT CONTROLLER

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1462 board. They
accept requests from peripherals, resolve priorities on pending interrupts in service, issue interrupt requests to the
CPU, and provide vectors which are used as acceptance indices by the CPU to determine which interrupt service
routine to execute.

Following is the system information of interrupt levels:

2.6 SERIAL PORT

The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are used to convert parallel data to a serial
format on the transmit side and convert serial data to parallel on the receiver side. The serial format, in order of
transmission and reception, is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one,
one and half (five-bit format only) or two stop bits. The ACEs are capable of handling divisors of 1 to 65535, and
produce a 16x clock for driving the internal transmitter logic.

Provisions are also included to use this 16x clock to drive the receiver logic. Also included in the ACE a completed
MODEM control capability, and a processor interrupt system that may be software tailored to the computing time
required handle the communications link.

The following table is summary of each ACE accessible register

NOTE: X presents not used.

Bit 7: This signal may become active during data entry, when the printer is off-line during printing, or when the

print head is changing position or in an error state. When Bit 7 is active, the printer is busy and can not
accept data.

Bit 6: This bit represents the current state of the printer’ s ACK signal. A0 means the printer has received the

character and is ready to accept another. Normally, this signal will be active for approximately 5
microseconds before receiving a BUSY message stops.

Bit 5: A1 means the printer has detected the end of the paper.

Bit 4: A1 means the printer is selected.

Bit 3: A0 means the printer has encountered an error condition.

Bit 5: Direction control bit. When logic 1, the output buffers in the parallel port are disabled allowing data driven

from external sources to be read; when logic 0, they work as a printer port. This bit is write only.

Bit 4: A1 in this position allows an interrupt to occur when ACK changes from low state to high state.

Bit 3: A1 in this bit position selects the printer.

Bit 2: A0 starts the printer (50 microseconds pulse, minimum).

Bit 1: A1 causes the printer to line-feed after a line is printed.

Bit 0: A0.5 microsecond minimum highly active pulse clocks data into the printer. Valid data must be present for

a minimum of 0.5 microseconds before and after the strobe pulse.

3.2 SYSTEM SETTING

Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks.

(A jumper block is a small plastic-encased conductor [shorting plug] that slips over the pins.) To change a jumper
setting, remove the jumper from its current location with your fingers or small needle-nosed pliers. Place the
jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not
to bend the pins.

We will show the locations of the AR-B1462 jumper pins, and the factory-default setting.

CAUTION: Do not touch any electronic component unless you are safely grounded. Wear a grounded wrist strap

or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can
permanently damage electronic components.

The AR-B1462 accepts many types of microprocessors such as Intel/AMD/Cyrix 486DX/DX2/DX4. All of these
CPUs include an integer processing unit, floating-point processing unit, memory-management unit, and cache.
They can give a two to ten-fold performance improvement in speed over the 386 processor, depending on the
clock speeds used and specific application. Like the 386 processor, the 486 processor includes both segment­based and page-based memory protection schemes. The instruction of processing time is reduced by on-chip
instruction pipelining. By performing fast, on-chip memory management and caching, the 486 processor relaxes
requirements for memory response for a given level of system performance.

3.3 ETHERNET CONTROLLER

The Ethernet controller of the AR-B1462 is a highly integrated design that provides all Media Access Control
(MAC) and Encode-Decode (ENDEC) functions in accordance with the IEEE 802.3 standard. Network interfaces
include 10BASE5 or 10BASE2 Ethernet via 10BASE-T via the Twisted-pair. The Ethernet controller can interface
directly to the PC-AT ISA bus without any external device. The interface to PC-AT ISA bus is fully compatible with
NE2000 Ethernet adapter cards, so all software programs designed for NE2000 can run on the Ethernet controller
card without any modification.

Microsoft’ s Plug and Play and the jumperless software configuration function are both supported. The capability of
the PnP and Non-PnP mode autoswitch function allows users to configure network card. No jumpers or switches
are needed to set when using either the PC or PnP function. The integrated 8KX16 SRAM and 10BASE-T
transceiver make Ethernet controller more cost-effective.

Step 5 : Plug the CPU card into a free AT-bus slot or PICMG slot on the backplane and secure it in place with

a screw to the system chassis.

Step 6 : Connect all necessary cables. Make sure that the FDC, HDC, serial and parallel cables are

connected to pin 1 of the related connector.

Step 7 : Connect the hard disk/floppy disk flat cables from the CPU card to the drives. Connect a power

source to each drive.

Step 8 : Plug the keyboard into the keyboard connector.

Step 9 : Turn on the power.

Step 10: Configure your system with the BIOS Setup program then re-boot your system.

Step 11: If the CPU card does not work, turn off the power and read the hardware description carefully again.

Step 12: If the CPU card still does not perform properly, return the card to your dealer for immediate service.

5.2 UTILITY DISKETTE

AR-B1462 provides two VGA driver diskettes, support WIN31, WIN95, WINNT 4.0 & OS/2; and one audio driver
diskette. If your operating system is the other operating system, please attach Acrosser that will provide the
technical supporting for the VGA resolution.

There are two diskettes: disk#2 is for WIN31, WIN95 & WINNT4.0 VGA resolution, disk#3 is for WINNT3.5 and

(2) SSD Utility

To support the AR-B1462 solid state disk’ s operations, the following files have been provided on the enclosed
diskette #3’ s directory <SSD>.

(A) WD1462.EXE

WD1462.EXE This program demonstrates how to enable and trigger the watchdog timer. It allows you to

test the <TIMES-OUT & RESET> function when the watchdog timer is enabled.

(B) WP1462.EXE

WP1462.EXE This program demonstrates how to enable and disable software write protected function. It

also shows the current protect mode of write or read only memory.

(C) RFG.EXE

RFG.EXE This program is used to generate ROM pattern files in a binary format. Each ROM pattern file

has the same size as the FLASH or EPROM and can be easily programmed on to the FLASH
with on-board programmer or on to EPROM with any EPROM programmer. If you have
specified a DOS drive in the *.PGF file, RFG will generate bootable ROM pattern files for the
EPROM or FLASH disk. The RFG supports the following DOS, MS-DOS, PC-DOS, DR-DOS,
and X-DOS.

NOTE: If you want to use AR-B1462 with any DOS which is not supported by RFG, please send your requirement

to Acrosser Technology Co., Ltd. or contract with your local sales representative.

The RFG.EXE provided in the utility diskette is a program that converts the files you list in the PGF and convert
them into ROM pattern file. The RFG will determine how many EPROMs are needed and generate the same
number of ROM pattern files. These ROM pattern files are named with the name assigned by the ROM_NAME in
the PGF and the extension names are *.R01, *.R02….etc. To generate ROM pattern files.
The ROM File Generator main menu will be displayed on the screen. There are 7 options on the main menu. They
serve the following functions:

Quit to DOS

Quits and exits to the DOS

OS Shell

Exits from the RFG temporarily to the DOS prompt. Type <EXIT> to return to the RFG main menu.

Load PFG File

If this option is used, the RFG will prompt you for the PGF file name. This option is useful if you have not
previously entered a PGF name or you wish to use a different PGF file. The RFG will check and display the
PGF filename, ROM pattern file name, EPROM capacity, DOS version and the number of ROM pattern files
that will be generated.

Type Current PGF File

This option instructs the RFG to use the DOS type command to display the contents of the current PGF file.

Generate ROM File(s)

If there is no mistake in your *.PGF file, then this menu option will generate ROM pattern files. The number
of ROM pattern file generated by the RFG will depend on the total capacity needed by your files. For
instance, if 3 files are generated, then you will need to use 3 EPROMs (The size depends upon the number
stated in your PGF). The ROM pattern files will have the same file names, but will have different extension
names. For example:

TEST.R01, TEST.R02, TEST.R03…etc.

Display Error in PGF File

This option displays errors that were detected in your PGF.

AR-B1462 User¡¦s Guide

Help to PGF File

This option gives information on how to write a PGF file and how to generate ROM pattern files. An
example PGF is also included.
Move the reverse video bar to <Generate ROM File(s)> then press [ENTER]. The ROM pattern file is a
binary file. The file size will be the same size as the EPROM that you assigned in the PGF. For example, if
you are using 128KX8 EPROM memory chips, then the size of ROM patterns file will be 131072 bytes. For
other chips the file size will be:

64KX8 EPROM----65536 bytes
256KX8 EPROM—262144 bytes
512KX8 EPROM---524288 bytes
1MX8 EPROM -----1048576 bytes

(D) RFGDEMO.PGF

RFGDEMO.PGF This file provides a sample PROGRAM GROUP FILE which illustrates how to create ROM

pattern files correctly.

The PGF is an ASCII text file that can be created by using any text editor, word processor or DOS <COPY CON>
command. The PGF lists what files will be copied and if DOS is going to be copied. This file can have any DOS
filename, but the extension name must be *.PGF. For example, followings are valid filenames.

RFGDEMO.PGF
MYRFG.PGF
MSDOS.PGF
….

An examples of the *.PGF file is as follow.

ROM_NAME=TEST1 ; ROM pattern file name is TEST1

;The output file names will be TEST1.R01,
;TEST1.R02..etc.

DOS_DRIVE=C: ; DOS system drive unit is drive C:

;If user does not want to copy DOS
;system files onto the ROM disk
;write as DOS_DRIVE=NONE

ROM_SIZE=128 ;64 means 64KX8 (28F512) EPROM

5.3 WATCHDOG TIMER

This section describes how to use the Watchdog Timer, disabled, enabled, and trigger.
The AR-B1462 is equipped with a programmable time-out period watchdog timer. User can use the program to
enable the watchdog timer. Once you have enabled the watchdog timer, the program should trigger it every time
before it times out. If your program fails to trigger or disable this timer before it times out because of system hang­up, it will generate a reset signal to reset the system. The time-out period can be programmed to be 3 to 42
seconds.

5.3.1 Watchdog Timer Setting

The watchdog timer is a circuit that may be used from your program software to detect crashes or hang-ups.
Whenever the watchdog timer is enabled, the LED will blink to indicate that the timer is counting. The watchdog
timer is automatically disabled after reset.
Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time before it
times-out. After you trigger the watchdog timer, it will be set to zero and start to count again. If your program fails
to trigger the watchdog timer before time-out, it will generate a reset pulse to reset the system or trigger the IRQ15
signal to tell your program that the watchdog is times out.
The factor of the watchdog timer time-out constant is approximately 6 seconds. The period for the watchdog timer
time-out period is between 1 to 7 timer factors.
If you want to reset your system when watchdog times out, the following table listed the relation of timer factors
between time-out period.

Table 5-1 Time-Out Setting

If you want to generate IRQ15 signal to warn your program when watchdog times out, the following table listed the
relation of timer factors between time-out period. And if you use the IRQ15 signal to warn your program when
watchdog timer out, please enter the BIOS Setup the <Peripheral Setup> menu, the <OnBoard PCI IDE> and <IDE
Prefetch> these two items must set to Primary.

NOTE: 1. If you program the watchdog to generate IRQ15 signal when it times out, you should initial IRQ15

interrupt vector and enable the second interrupt controller (8259 PIC) in order to enable CPU to process
this interrupt. An interrupt service routine is required too.

2. Before you initial the interrupt vector of IRQ15 and enable the PIC, please enable the watchdog timer
previously, otherwise the watchdog timer will generate an interrupt at the time watchdog timer is
enabled.

5.3.2 Watchdog Timer Enabled

To enable the watchdog timer, you have to output a byte of timer factor to the watchdog register whose address is
214H or Base Port. The following is a BASICA program which demonstrates how to enable the watchdog timer and
set the time-out period at 24 seconds.

1000 REM Points to command register
1010 WD_REG% = 214H
1020 REM Timer factor = 84H (or 0C4H)
1030 TIMER_FACTOR% = %H84
1040 REM Output factor to watchdog register
1050 OUT WD_REG%, TIMER_FACTOR%

.,etc.

5.3.3 Watchdog Timer Trigger

After you enable the watchdog timer, your program must write the same factor as enabling to the watchdog register
at least once every time-out period to its previous setting. You can change the time-out period by writing another
timer factor to the watchdog register at any time, and you must trigger the watchdog before the new time-out period
in next trigger. Below is a BASICA program which demonstrates how to trigger the watchdog timer:

2000 REM Points to command register
2010 WD_REG% = 214H
2020 REM Timer factor = 84H (or 0C4H)
2030 TIMER_FACTOR% = &H84
2040 REM Output factor to watchdog register
2050 OUT WD_REG%, TIMER_FACTOR%

.,etc.

5.3.4 Watchdog Timer Disabled

To disable the watchdog timer, simply write a 00H to the watchdog register.

3000 REM Points to command register
3010 WD_REG% = BASE_PORT%
3020 REM Timer factor = 0
3030 TIMER_FACTOR% = 0
3040 REM Output factor to watchdog register
3050 OUT WD_REG%, TIMER_FACTOR%

6. SOLID STATE DISK

The section describes the various type SSDs’ installation steps as follows. This chapter describes the procedure of
the installation. The following topics are covered:

l Overview
l Switch Setting
l Jumper Setting
l ROM Disk Installation
l DiskOnChip Installation

6.1 OVERVIEW

The AR-B1462 provides three 32-pin JEDEC DIP sockets which may be populated with up to 4MB of EPROM or
2MB of FLASH or 2MB of SRAM disk. It is ideal for diskless systems, high reliability and/or high speed access
applications, controller for industrial or line test instruments, and etc.

If small page (less or equal 512 bytes per page) 5V FLASHs were used, you could format FLASH disk and copy
files onto FLASH disk just like using a normal floppy disk. You can use all of the related DOS command (such as
COPY, DEL…etc.) to update files on the 5V FLASH disk.

The write protect function allows you to prevent your data on small page 5V FLASH or SRAM disk from accidental
deletion or overwrite.

Data retention of SRAM is ensured by an on-board Lithium battery or an external battery pack that could be
connected to the AR-B1462.

6.2 SWITCH SETTING

We will show the locations of the AR-B1462 switch, and the factory-default setting.

CAUTION: The switch setting needs to adjust with the jumpers setting, make sure the jumper settings and the

switch setting are correct.

and set the receiver to the inverse state of the transmitter. Receiver is disabled.

2. The receiver is always enabled, so you will receive data that you transmitted previously. It is not
recommended to use this setting as RS-485 interface.

6.3 JUMPER SETTING

Before installing the memory into memory sockets MEM1 through MEM4, you have to configure the memory type
which will be used (ROM/RAM) on the AR-B1462. Each socket is equipped with a jumper to select the memory
type.

You can configure the AR-B1462 as a (FLASH) EPROM disk (ROM only), a SRAM disk (SRAM only) or a
combination of (FLASH) EPROM and SRAM disk.

It is not necessary to insert memory chips into all of the sockets. The number of SRAM chips required depends on
your RAM disk capacity. The number of EPROM chips required depends on the total size of files that you plan to
copy onto the ROM disk and whether or not it will be bootable.

Insert the first memory chip into MEM1 if you are going to configure it as a ROM or SRAM disk. If you use a
combination of ROM and RAM, then insert the (FLASH) EPROM chip starting with the MEM1, and insert the
SRAM chips starting from the first socket which is configured as SRAM.

l M1:is used to configure the memory type of MEM1
l M2:is used to configure the memory type of MEM2
l M3:is used to configure the memory type of MEM3
l M4:is used to configure the memory type of MEM4

CAUTION: When the power is turned off, please note the following precautions.

1. If your data has been stored in the SRAM disk, do not change the jumper position or data will be
lost.

2. Make sure jumpers are set properly. If you mistakenly set the jumpers for SRAM and you have
EPROM or FLASH installed, the EPROM or FLASH will drain the battery’ s power.

7.1 BIOS SETUP OVERVIEW

BIOS is a program used to initialize and set up the I/O system of the computer, which includes the ISA bus and
connected devices such as the video display, diskette drive, and the keyboard.
The BIOS provides a menu-based interface to the console subsystem. The console subsystem contains special
software, called firmware that interacts directly with the hardware components and facilitates interaction between
the system hardware and the operating system.
The BIOS Default Values ensure that the system will function at its normal capability. In the worst situation the
user may have corrupted the original settings set by the manufacturer.
After the computer turned on, the BIOS will perform a diagnostics of the system and display the size of the
memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu will
show on the screen.
The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight the option that you
wish to modify, and then press the [Enter] key to assure the option and configure the functions.

the month, day and year format.

Highlight the <Time> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current date. Follow

the hour, minute and second format.
The user can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information on how to
create this file, please refer to the MS-DOS manual.

Floppy Setup

The <Standard CMOS Setup> option records the types of floppy disk drives installed in the system.

To enter the configuration value for a particular drive, highlight its corresponding field and then select the drive type
using the left-or right-arrow key.

Hard Disk Setup

The BIOS supports various types for user settings, The BIOS supports <Pri Master> and <Pri Slave> so the user
can install up to two hard disks. For the master and slave jumpers, please refer to the hard disk’ s installation
descriptions and the hard disk jumper settings.
You can select <AUTO> under the <TYPE> and <MODE> fields. This will enable auto detection of your IDE drives
during bootup. This will allow you to change your hard drives (with the power off) and then power on without
having to reconfigure your hard drive type. If you use older hard disk drives which do not support this feature, then
you must configure the hard disk drive in the standard method as described above by the <USER> option.

Boot Sector Virus Protection

This option protects the boot sector and partition table of your hard disk against accidental modifications. Any

attempt to write to them will cause the system to halt and display a warning message. If this occurs, you can either
allow the operation to continue or use a bootable virus-free floppy disk to reboot and investigate your system. The
default setting is <Disabled>. This setting is recommended because it conflicts with new operating systems.
Installation of new operating system requires that you disable this to prevent write errors.

BootUp Num-Lock

This item is used to activate the Num-Lock function upon system boot. If the setting is on, after a boot, the Num­Lock light is lit, and user can use the number key.

Floppy Drive Swap

The option reverses the drive letter assignments of your floppy disk drives in the Swap A, B setting, otherwise
leave on the default setting of Disabled (No Swap). This works separately from the BIOS Features floppy disk
swap feature. It is functionally the same as physically interchanging the connectors of the floppy disk drives. When
the setting is <Enabled>, the BIOS will be swapped floppy drive assignments so that Drive A becomes Drive B,
and Drive B becomes Drive A under DOS.

Floppy Drive Seek

If the <Floppy Drive Seek> item is setting Enabled, the BIOS will seek the floppy <A> drive one time upon bootup.

Mouse Support

The setting of Enabled allows the system to detect a PS/2 mouse on bootup. If detected, IRQ12 will be used for
the PS/2 mouse. IRQ 12 will be reserved for expansion cards if a PS/2 mouse is not detected. Disabled will
reserve IRQ12 for expansion cards and therefore the PS/2 mouse will not function.

Typematic Rate

7.10 BIOS UPDATE

The BIOS program instructions are contained within computer chips called FLASH ROMs that are located on your
system board. The chips can be electronically reprogrammed, allowing you to upgrade your BIOS firmware
without removing and installing chips.

The AR-B1462 BIOS provides a menu-based interface to the console subsystem. The console subsystem
contains special software, called firmware that interacts directly with the hardware components and facilitates
interaction between the system hardware and the operating system.

The AR-B1462 provides FLASH BIOS update function for you to easily upgrade newer BIOS version. Please
follow the operating steps for updating new BIOS:

Step 1: Insert the FLASH BIOS diskette into the floppy disk drive.

Step 2: Turn on your system and press [Ctrl]+[Home[ (Hit the [Ctrl] key and [Home] key simultaneously just

powered on. Then the onboard BIOS will read new BIOS file named and AMIBOOT.ROM from
floppy drive and write to FLASH.

Step 3: If all steps is correctly, the system will reboot. But the system did not boot up, please check

everything and try again. If still not work, please contact your Acrosser distributor for technology
supports at once.

NOTE: 1. After turn on the computer and the system didn’ t detect the boot procedure, please press the

[Ctrl]+[Home] key immediately. The system will detect the BIOS file from floppy drive.

2. The BIOS Flash disk is not the standard accessory. It supports to add some functions, if it is
necessary to update in the future. User can download the suitable BIOS. The address is as

10. PROGRAMMING RS-485 & INDEX

10.1 PROGRAMMING RS-485

The majority communicative operation of the RS-485 is in the same of the RS-232. When the RS-485 proceeds
the transmission which needs control the TXC signal, and the installing steps are as follows:

Step 1: Enable TXC

Step 2: Send out data

Step 3: Waiting for data empty

Step 4: Disable TXC

NOTE: Please refer to the section of the “Serial Port” in the chapter “System Control” for the detail description of

the COM port’ s register.

(1) Initialize COM port

Step 1: Initialize COM port in the receiver interrupt mode, and /or transmitter interrupt mode. (All of the

communication protocol buses of the RS-485 are in the same.)

Step 2: Disable TXC (transmitter control), the bit 0 of the address of offset+4 just sets “0”.

NOTE: Control the AR-B1462 CPU card’ s DTR signal to the RS-485’ s TXC communication.

(2) Send out one character (Transmit)

Step 1: Enable TXC signal, and the bit 0 of the address of offset+4 just sets “1”.

Step 2: Send out the data. (Write this character to the offset+0 of the current COM port address)

Step 3: Wait for the buffer’ s data empty. Check transmitter holding register (THRE, bit 5 of the address of

offset+5), and transmitter shift register (TSRE, bit 6 of the address of offset+5) are all sets must be
“0”.

Step 4: Disabled TXC signal, and the bit 0 of the address of offset+4 sets “0”

(3) Send out one block data (Transmit – the data more than two characters)

Step 1: Enable TXC signal, and the bit 0 of the address of offset+4 just sets “1”.

Step 2: Send out the data. (Write all data to the offset+0 of the current COM port address)

Step 3: Wait for the buffer’ s data empty. Check transmitter holding register (THRE, bit 5 of the address of

offset+5), and transmitter shift register (TSRE, bit 6 of the address of offset+5) are all sets must be
“0”.

Step 4: Disabled TXC signal, and the bit 0 of the address of offset+4 sets “0”

(4) Receive data

The RS-485’ s operation of receiving data is in the same of the RS-232’ s.
