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.

2. SYSTEM CONTROLLER

This chapter describes the major structure of the AR-B1564 CPU board. The following topics are covered:

! DMA Controller
! Keyboard Controller and PS/2 Mouse
! Interrupt Controller
! Serial Port
! Parallel Port

2.1 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the AR-B1564 board. Each controller is a four­channel DMA device, which will generate the memory addresses and control signals necessary to transfer
information directly between a peripheral device and memory. This allows high-speed information tran sfer wit h le ss
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 AND PS/2 MOUSE

The 8042 processor is programmed to support the serial keyboard and PS/2 mouse 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”
interrupt may be used for both send and receive routines.

When using the PS/2 mouse interface, it will save 1 COM port. But it will also occupy IRQ12 interrupt level.

AR-B1564 User’s Guide

2.3 INTERRUPT CONTROLLER

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1564 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:

2.4 SERIAL PORT

The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are not only used to convert parallel data to a
serial format on the transmit side but also used to 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 not only included the use of 16x clock to drive the receiver logic. But also included in the ACE as 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

The parallel portion of the SMC37C669 makes the attachment of various devices that accept eight bits of parallel
data at standard TTL level.

(3) Data Swapper

The system microprocessor can read the contents of the printer’s Data Latch through the Data Swapper by reading
the Data Swapper address.

AR-B1564 User’s Guide

(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:

12345670

XXX

-ERROR
SLCT
PE

-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. 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.

(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:

XX

12345670

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 writing 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 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 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-B1564 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.

mode.

NOTE: 1. The recommended configuration for RS-485 interface is to set the transmitter to the controlled by DTR

and set 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.

The BUSCLK signal of the I/O channel is asynchronous
to the CPU clock.
This signal goes high during power-up, low line-voltage or
hardware reset
The System Address lines run from bit 0 to 19. They are
latched onto the falling edge of "BALE"
The Unlatched Address line run from bit 17 to 23

System Data bit 0 to 15

The Buffered Address Latch Enable is used to latch
SA0 – SA19 onto the falling edge. This signal is forced
high during DMA cycles
The I/O Channel Check is an active low signal which
indicates that a parity error exist on the I/O board
This signal lengthens the I/O, or memory read/write cycle,
and should be held low with a valid address
The Interrupt Request signal indicates I/O service request
attention. They are prioritized in the following sequence :
(Highest) IRQ 9, 10, 11, 12, 13, 15, 3, 4, 5, 6, 7 (Lowest)
The I/O Read signal is an active low signal which
instructs the I/O device to drive its data onto the data bus
The I/O write signal is an active low signal which instructs
the I/O device to read data from the data bus
The System Memory Read is low while any of the low
1mega bytes of memory are being used
The Memory Read signal is low while any memory
location is being read
The System Memory Write is low while any of the low
1mega bytes of memory is being written
The Memory Write signal is low while any memory
location is being written
DMA Request channels 0 to 3 are for 8-bit data transfers.
DMA Request channels 5 to 7 are for 16-bit data
transfers. DMA request should be held high until the
corresponding DMA has been completed. DMA request
priority is in the following sequence:(Highest) DRQ 0, 1,
2, 3, 5, 6, 7 (Lowest)
The DMA Acknowledges 0 to 3, 5 to 7 are the
corresponding acknowledge signals for DRQ 0 to 3 and 5
to 7
The DMA Address Enable is high when the DMA
controller is driving the address bus. It is low when the
CPU is driving the address bus
This signal is used to indicate a memory refresh cycle
and can be driven by the microprocessor on the I/O
channel
Terminal Count provides a pulse when the terminal count

3.2.7 CPU Setting

The AR-B1564 accepts many types of 586 microprocessor, such as INTEL Pentium, AMD-K5, AMD-K6, and
CYRIX 6x86. All of these CPUs include an integer processing unit, floating-point processing unit, memory­management unit, and cache. They can give a two to en-fold performance improvement in speed over the 486
processor, which is depending on the clock speeds used and specific application. Like the 486 processor, the 586
processor includes both segment-based and page-based memory protection schemes. Instruct processing time
has reduced by on-chip instruction pipelining. By performing fast, on-chip memory management and caching, the
586 processor relaxes requirements for memory response for a given level of system performance.

3.2.14 USB Connector (CN2)

USB is the abbreviation of Universal Serial Bus. The Universal Serial Bus (USB) standard is a low-to-medium
speed interface for the connection of PC peripherals.
The USB standard simplifies the connection of peripherals to PCs with a uniform hardware and software interface.
Personal computers equipped with USB allow computer peripherals to be automatically configured as soon as they
are physically attached - without the need to reboot or run setup.
USB is a leading edge technology that allows the user to quickly and easily adding wide range peripheral devices
from printers to keyboards and telephony devices to fax/modems. Universal Host Controller Interface (UHCI) and
future support for the Open Host Controller Interface (OHCI) ensure USB compatibility and usability well into the
future.
The connector on the CPU board supports two Universal Serial Bus ports. An optional external port bracket
attaches to the onboard connector via an attached cable. With the optional port bracket installed you can attach
USB devices to the external ports. If the USB ports are installed, the USB Controller line in the Integrated
Peripherals section of the CMOS Setup utility must be set to “Enabled”. USB ports may also require Operating
System support for USB devices.

The inverter board is the one that supplies the high voltage signals to drive the LCD panel by converting the 12
volt signal from the AR-B1564 into 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.

The AR-B1564 supports CRT colored monitor, STN, Dual-Scan, TFT, monochrome and color panels. It can be
connected to create a compact video solution for the industrial environment. 2MB of RAM on-boarded allows a
maximum CRT resolution of 1024X768 with 64K colors and a LCD resolution of 800X600 with 64K colors. For
different VGA display modes, your monitor must possess certain characteristics to display the mode you want.

6.3 WATCHDOG TIMER

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

The AR-B1564 is equipped with a programmable time-out period watchdog timer. Your program can enable this
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.

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 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
IRQ7/IRQ10 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.

Table 6-3 Time-Out Setting

NOTE:

1. If you program the watchdog to generate IRQ7/IRQ10 signal when it times out, you should initialize
IRQ7/IRQ10 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 IRQ7/IRQ10 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.

6-7

AR-B1564 User’s Guide

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 w atchdog 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

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 will 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.

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.

7.3 ADVANCED CMOS SETUP

The <Advanced CMOS Setup> option consists of configuration entries that allow you to improve your system
performance, or let you set up some system features according to your preference. Some entries here are
required by the CPU board’s design to remain in their default settings.

Disable TXC

the COM port’s register.

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.)

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

Control the AR-B1564 CPU card’s DTR signal to the RS-485’s TXC communication.

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 th e buffer’s dat a empty. Check tr ansmitter hol ding regist er (THRE, bit 5 of t he address of
offset+5), and transmitter shift register (TSRE, bit 6 of the address of offset+5) are all sets must be
“0”.
