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 ACE-9140 is including the AR-B9140, AR-B9438, AR-B9437 and AR-B9432, and the AR-B9140, AR-B9432
and AR-B9437 are mounted on one bracket. The main part of the ACE-9140 is AR-B9140, so the major of the
manual describes the AR-B9140’s functions. The ACE-9140’s combination describes in the Chapter “Installation”.

The AR-B9140 is a half size industrial grade CPU card that has been designed to withstand continuous operation
in harsh environments. The AR-B9140 supports on-board memory 8MB, and extends to 40MB DRAM for using
one 72-pin SIMM.

The 6 layers PCB CPU card is equipped with a IDE HDD interface, a floppy disk drive adapter, 1 parallel port, 2
serial ports and a watchdog timer. Its dimensions are as compact as 121.9mmX184.9mm. 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.

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.

The AR-B9140 is implemented with M1487 and M1489 chipset incorporate a memory controller, parity generation
and checking, two 8237 DMA controllers, two 8259 interrupt controllers, one 8254 timer/counter, an address buffer
and a data buffer.

A super I/O chip (SMC37C669) is embedded in the AR-B9140 card. It combines functions of a floppy disk drive
adapter, a hard disk drive (IDE) adapter, two 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.

2. SYSTEM CONTROLLER

This chapter describes the major structure of the AR-B9140 CPU board. The following topics are covered:

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

2.1 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the AR-B9140 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 t ransfer 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

ACE-9140 User’s Guide

2.3 INTERRUPT CONTROLLER

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B9140 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:

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

-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 can not
accept data.

Bit 6: This bit represents the current state of the printer’s ACK signal. A 0 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: A 1 means the printer has detected the end of the paper.

Bit 4: A 1 means the printer is selected.

Bit 3: A 0 means the printer has encountered an error condition.

XX

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: A 1 in this position allows an interrupt to occur when ACK changes from low state to high state.

Bit 3: A 1 in this bit position selects the printer.

Bit 2: A 0 starts the printer (50 microseconds pulse, minimum).

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

Bit 0: A 0.5 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.

3.2.11 CPU Setting

The AR-B9140 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.

The block diagram shows that the AR-B9140 still needs components to use with a LCD panel. The inverter board
provides the control for the brightness and the contrast of the LCD panel. The inverter is also the components that
supply the high voltage to drive the LCD panel. Each item will be explained further in the section.

NOTE: Be careful with the pin orientation when installing connectors and the cables. A wrong connection can easily

destroy your LCD panel. Pin 1 of the cable connector is indicated with a sticker and pin1 of the ribbon
cable is usually has a different color.

4.2.1 Inverter Board Description

The inverter board supplies high voltage signals to drive the LCD panel by converting the 12 volt signal from the
AR-B9140 into a high voltage AC signal for LCD panel. It can be installed freely on the space provided over the
VR board. If the VR board is installed on the bracket, you have to provide a place to install the inverter board into
your system.

6.3 WATCHDOG TIMER

This section describes how to use the Watchdog Timer, disabled, enabled, and trigger.
The AR-B9140 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.

6.3.1 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 wa tchdog 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.

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.

ACE-9140 User’s Guide

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.

6.3.2 Watchdog Timer Enabled

To enable the watchdog timer, you have to output a byte of timer factor to the watchdog register whose address is
76H. The following is a BASICA program which demonstrates how to enable the watchdog timer and set the time­out period at 24 seconds.

1000 REM Points to command register
1010 WD_REG% = 76H
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.

6.3.3 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% = 76H
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.

6.3.4 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% = 76H
3020 REM Timer factor = 0
3030 TIMER_FACTOR% = 0
3040 REM Output factor to watchdog register
3050 OUT WD_REG%, TIMER_FACTOR%

7.1BIOS 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.

These options determine where the system looks first for an operating system.

Quick Boot

This category speeds up Power On Self Test (POST) after you power on the computer. If it is set to Enabled,
BIOS will shorten or skip some check items during POST.

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 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
<Enabled>, the BIOS 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.

PS/2 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

This item specifies the speed at which a keyboard keystroke is repeated.

System Keyboard

This function specifies that a keyboard is attached to the computer.

Primary Display

The option is used to set the type of video display card installed in the system.
