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. OVERVIEW

This chapter provides an overview of your system features and capabilities. The following topics are covered:

Introduction

Packing List

Features

1.1 INTRODUCTION

The AR-B1375 and AR-B1376 are new generation half size, 386 ISA card. This card offers much greater performance

than the older cards such as support for 32MB’s of DRAM using two 72-pin SIMMs, one RS-232C/485 and one RS-232C

port and 3/1.5MB solid state disk capacity for ROM, FLASH and SRAM.

The unit also comes with a programmable watchdog timer and other typical interfaces. These 386 CPU cards are excellent

for embedded systems, MMI’s, workstations, medical applications or POS/POI systems. As well, an RS-232C/485 port

provided remote control. RS-485 has not been offered until recently on 386 cards.

Especially the AR-B1376 with on board VGA, offers the most exciting possibilities yet to the industry. The on board

VGA/LCD controller brings about a whole new dimension of industrial computing. No longer do you have to worry about

adding an extra card to your system. Negating the need of a separate VGA card saves space. The VGA/LCD unit comes

with 1MB of V-RAM on board and uses the C&T 65545 Chipset, to support a wide range of LCD Panels.

1.2 PACKING LIST

The accessories are included with the system. Before you begin installing your AR-B1375 or AR-B1376 board,

take a moment to make sure that the following items have been included inside the AR-B1375 or AR-B1376

package.

2. SYSTEM CONTROLLER

This chapter describes the major structure of the AR-B1375 and AR-B1376 CPU board. The following topics are

covered:

Microprocessor

DMA Controller

Keyboard Controller

Interrupt Controller

Real-Time Clock and Non-Volatile RAM

Timer

Serial Port

Parallel Port

2.1 MICROPROCESSOR

The AR-B1375 and AR-B1376 use the ALI M6117 CPU, it is designed to perform like Intel’s 386SX system with

deep green features.

The 386SX core is the same as M1386SX of Acer Labs. Inc. and 100% object code compatible with the Intel

386SX microprocessor. System manufacturers can provide 386 CPU based systems optimized for both cost and

size. Instruction pipelining and high bus bandwidth ensure short average instruction execution times and high

system throughput. Furthermore, it can keep the state internally from charge leakage while external clock to the

core is stopped without storing the data in registers. The power consumption here is almost zero when clock stops.

The internal structure of this core is 32-bit data and address bus with very low supply current. Real mode as well

as Protected mode are available and can run MS-DOS, MS-Windows, OS/2 and UNIX.

2.2 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the AR-B1375/AR-B1376 board. Each controller

is a four-channel 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

Channel 0: Spare

DMA Controller 2

Channel 4: Cascade for controller 1

Channel 5: Spare

Channel 1: IBM SDLC

Channel 2: Diskette adapter

Channel 3: Spare

AR-B1375/AR-B1376 User’s Guide

2.3 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.

2.4 INTERRUPT CONTROLLER

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1375/AR-B1376

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:

2.7 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.

(4) Printer Status Buffer

The system microprocessor can read the printer status by reading the address of the Printer Status Buffer. The bit

definitions are described as follows:

-ERROR

SLCT

-ACK

-BUSY

Figure 2-2 Printer Status Buffer

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 cannot

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.

(5) Printer Control Latch & Printer Control Swapper

The system microprocessor can read the contents of the printer control latch by reading the address of printer

control swapper. Bit definitions are as follows:

STROBE

AUTO FD XT

INIT

SLDC IN

IRQ ENABLE

DIR(write only)

Figure 2-3 Bit’s Definition

NOTE: X presents not used.

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-B1375 and AR-B1376 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.

5.2.2 SSD Utility

To support the AR-B1375/AR-B1376 solid-state disk’s operations, the following files have been provided on the

enclosed diskette’s directory <SSD>.

(A) PGM137x.EXE

PGM137x.EXE PGM137x.EXE is used to program the 12V FLASH EPROM after the ROM pattern files are

generated by RFG.EXE. The PGM137x.EXE can also program the correctness of the ROM

pattern files onto 5V FLASH EPROM (start from MEM1) or SRAM for testing the ROM pattern

files.

To execute PGM137x.EXE, the main menu will be displayed on your screen. There are 8 options on the main

menu.

Quit to DOS

Quits and exits to the DOS.

OS Shell

Exits from PGM137x temporarily to the DOS prompt. Type EXIT to return to PGM137x main menu.

Load ROM File

If this option is used, the PGM137x will prompt you for the ROM pattern file name. This option is useful if

you have not previously entered a ROM pattern file name or if you wish to use a different ROM pattern file.

The PGM137x will check and display the ROM file name, ROM file size, (FLASH) memory capacity and the

number of ROM pattern files that will be loaded and copied onto the (FLASH) memory chips.

Verify Memory

If ROM pattern files were loaded without error, this option instructs PGM137x to verify the contents of

(FLASH) memory chips with the current ROM pattern files.

Program Memory

If there are no mistakes in your ROM pattern file, then this menu option will erase (FLASH) memory, write

the current ROM pattern files onto (FLASH) memory and verify data that was just written to (FLASH)

memory, using the ROM pattern files.

Memory Type/Mfr.

Before you program the (FLASH) memory chips, make sure that the FLASH’s type and manufactory match

the one shown on the main menu. Otherwise, you can use this option to select the proper type and

manufacture and instruct the program to use a right programming algorithm.

Select PGM Chips

Normally the PGM137x will program all ROM pattern files onto the FLASH memories with the ROM pattern

files just loaded. But you can use this option to select which memory chips that you want to program and

which memory chips need to be skipped. The PGM137x will only program the selected chips when writing

data to the FLASH memory. This is very useful when some of the memory chip were verified and

programmed previously.

Select FLASH PLSCNTs

If the 12V FLASHs have been programmed several times, please select the <Slowest> FLASH PLSCNT

mode instead of <Standard> mode. In the <Slower> or <Slowest> mode, PGM137x.EXE will retry more

times to program data onto the 12V FLASHs correctly. The default setting is <Slowest> mode.

(B) WD137x.EXE

WD137x.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.

WP137x.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.

(D) 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-B137x 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.

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

5.4 WATCHDOG TIMER

This section describes how to use the Watchdog Timer, disabled, enabled, and trigger.

The AR-B1375/AR-B1376 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 hang-up, it will generate a reset signal to reset the system. The time-out period can be programmed to be

3 to 42 seconds.

5.4.1 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 periods.

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.

5.4.2 Watchdog Timer Enabled

To enable the watchdog timer, you have to output a byte of timer factor to the watchdog register whose address is

The section describes the various type SSDs’ installation steps as follows. This chapter describes the procedure of

the installation. The following topics are covered:

Overview

Switch Setting

Jumper Setting

ROM Disk Installation

6.1 OVERVIEW

The AR-B1375 and AR-B1376 provides three 32-pin JEDEC DIP sockets, which may be populated with up to 3MB

of EPROM or 1.5MB of FLASH or 1.5MB 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.

An on-board Lithium battery or an external battery pack that could be connected ensures data retention of SRAM

to the AR-B1375 and AR-B1376.

6.2 SWITCH SETTING

We will show the locations of the AR-B1375 and AR-B1376 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.

6.3 JUMPER SETTING

Before installing the memory into memory sockets MEM1 through MEM3 (U31, U32 and U33 respectively), you

have to configure the memory type which will be used (ROM/RAM) on the AR-B1375 and AR-B1376. Each socket

is equipped with an jumper to select the memory type.

You can configure the AR-B1375 and AR-B1376 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.

M1:is used to configure the memory type of MEM1

M2:is used to configure the memory type of MEM2

M3:is used to configure the memory type of MEM3

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.

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.

This item is used to activate the Num-Lock function upon system boot. If the setting is on, after a boot, the Num-

Lock 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.

9. USING MEMORY BANKS

This appendix provides the information about how to access the memory on the AR-B1375 and AR-B1376 without

using the AR-B1375 and AR-B1376 SSD BIOS. The AR-B1375 and AR-B1376 hardware divides every 8K bytes of

memory into a memory bank. To access the data in the memory, you have to assign the chip number and the bank

number. On every chip, the memory bank number starts from zero. The last memory bank number depends on the

size of the memory chip used on the AR-B1375 and AR-B1376. For example, if you use the 256K bytes memory

chip, the bank number on every chip would be in the range of 0 to 31. The chip numbers and the bank numbers

are determined by the bank select register on the AR-B1375 and AR-B1376.

The I/O address of these registers are determined by SW1-1. The memory address of the memory bank is located

on the range selected by SW1-2.

The I/O port address of the bank select register is base port+0, and the I/O port address of the chip select register

is base port +2. The following is the format of the bank select register and bank enable register.

Example 1:

Select the 10th bank of the MEM1 on the AR-B1375 and AR-B1376. The AR-B1375 and AR-B1376

is using 27C020 (256K*8), and the base port is &H210.

11. PROGRAMMING RS-485 & INDEX

11.1 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:

Step 2:

Step 3:

Step 4:

Enable TXC

Send out data

Waiting for data empty

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:

NOTE:

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

Control the AR-B1375/AR-B1376 CPU card’s DTR signal to the RS-485’s TXC communication.

(2) Send out one character (Transmit)

Step 1:

Step 2:

Step 3:

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

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

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:

Step 2:

Step 3:

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

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

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.
