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 that may result in
expensive repairs. The following measures should generally be sufficient to protect your equipment from
static discharge:
1) Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a
grounded wrist strap).
2) When unpacking and handling the board or other system components, place all materials on an
antic static surface.
3) Be careful not to touch the components on the board, especially the “golden finger”connectors
on the bottom of every board.

covered:
lIntroduction
lPacking List
lFeatures
1.1 INTRODUCTION
The AR-B1380/AR-B1380A is a new generation half size, 386 ISA interface card. This card offers much greater
performance than the older cards such as support for 20MB DRAM using one 72-pin SIMM bank, 42 pin two SOJ
one RS-232C/485 connector and one RS-232C port and 3MB/1.5MB/1.5MB solid state disk capacity for EPROM,
FLASH and SRAM.
The 6 layer PCB CPU board is equipped with an IDE HDD interface, a floppy disk interface, 1 parallel port, and 2
serial ports and a watchdog timer. It provides 2 bus interfaces, ISA bus and a PC/104 compatible expansion bus.
Based on the PC/104 expansion bus, you could easily install numerous PC/104 modules. This 386 CPU card is
excellent for embedded systems, MMI’s, work stations, medical applications or POS/POI systems. As well, an RS-
232C/485 port is provided for remote control capabilities. RS-485 has not been offered until recently on 386 cards.
A watchdog timer, which 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.
For diskless application, the AR-B1380/AR-B1380A provides up to 3 MB of bootable EPROM, FLASH, or SRAM
disk by using 64Kx8 to 1Mx8 memory chips.
The AR-B1380A has VGA and LAN onboard, and offers the most exciting possibilities yet to the industry. The
onboard 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. Space is saved by eliminating the need for a separate VGA
card. 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.

2. SYSTEM CONTROLLER
This chapter describes the major structure of the AR-B1380/AR-B1380A CPU board. The following topics
are covered:
lMicroprocessor
lDMA Controller
lKeyboard Controller
lInterrupt Controller
lReal-Time Clock and Non-Volatile RAM
lTimer
lSerial Port
lParallel Port
lSolid State Disks
lEthernet Controller
lVGA Controller
2.1 MICROPROCESSOR
The AR-B1380/AR-B1380A uses 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 the 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 minimize charge leakage while the
external clock is stopped, without storing the data in registers. The power consumption here is almost zero
when the clock stops. The internal structure of this core is 32-bit and it’s address bus with a 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-B1380/AR-B1380A CPU 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 speed
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.
The following is the system DMA channel.
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 2-1DMA Channel Controller

AR-B1380/AR-1380A User’s Guide

2.3 KEYBOARD CONTROLLER
The 8042 processor is programmed to support a 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 the keyboard controller until an acknowledgment is received for the previous byte. 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-B1380/AR-
B1380A board. They accept requests from the peripherals, resolve priorities on pending interrupts in
service, issue interrupt requests to the CPU, and provide vectors which are used as acceptance indexed by
the CPU to determine which interrupt service routine should be executed.
The following is the system interrupt levels:
IRQ8 : Real time clock
IRQ9 : Rerouting to INT 0Ah from hardware IRQ2
IRQ10 : LAN
IRQ11 : Reserved for watchdog
IRQ12 : Spare
IRQ13 : Math. coprocessor

2.6 TIMER
The AR-B1380/AR-B1380A provides three programmable timers, each with a timing frequency of 1.19 MHz.
Timer 0 The output of this timer is tied to interrupt request 0. (IRQ 0)
Timer 1 This timer is used to trigger memory refresh cycles.
Timer 2 This timer provides the speaker tone.
Application programs can load different counts into this timer to generate various sound
frequencies.
2.7 SERIAL PORTS
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, 1.5 (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
complete MODEM control capability, and a processor interrupt system that may be software tailored to the
computing time required to handle the communications link.
The following table is a summary of each ACE accessible register

-BUSY
Figure 2-2 Printer Status Buffer
NOTE: X represents 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.
(5) Printer Control Latch & Printer Control Swapper
The system microprocessor can read the contents of the printer control latch by reading the address of

NOTE: X represents 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.
2.9 SOLID STATE DISKS
The AR-B1380/1380A provides three JEDEC DIP sockets and supports three kinds of solid state disks,
EPROM, FLASH, and SRAM. With EPROM, the total memory is up to 3MB, and FLASH or `SRAM is up to
1.5MB. The three sockets can be configured as three sockets for SSD or two sockets for SSD plus 1
socket for DiskOnChip. The DiskOnChip socket supports memory from 2MB to 144MB. The
DiskOnModule is connected to the onboard IDE connector. All the flash disks are ideal for diskless
systems, and are also highly reliable for high-speed access applications, as controllers for industrial use, or
line test instruments, etc.
2.10 ETHERNET CONTROLLER
The Ethernet controller of the AR-B1380A 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. The
Ethernet controller can interface directly with 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 the NE2000 standard 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 auto switch function allows the users to configure network cards.
No jumpers or switches are needed to set additionally when using either the PC or PnP function. The
integrated 8Kx16 SRAM and 10BASE-T transceiver make the Ethernet controller more cost-effective.
Caution: AR-B1380A doesn’t support the application of LAN Boot.
2.11 VGA CONTROLLER
AR-B1380A provides a super VGA controller for CRT and LCD displays. It supports CRT color monitors,
STN, Dual-Scan, TFT (see note below), monochrome and color panels. It can be connected to create a
compact video solution for the industrial environment. 1MB of VRAM on-boarded allows a maximum CRT
resolution of 1280X1024 and a LCD resolution of 640X480 with 64K colors. TFT resolution can be set at
640X480 or at 800X600. It fulfills the needs for higher graphics performance.

3.3 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.
