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:

lIntroduction

lPacking List

lFeatures

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:

lDMA Controller

lKeyboard Controller

lInterrupt Controller

lReal-Time Clock and Non-Volatile RAM

lTimer

lSerial Port

lParallel Port

2.1 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the AR-B1462 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 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

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.

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:

IRQ8 : Real time clock

IRQ9 : Rerouting to INT 0Ah from hardware IRQ2

IRQ10 : Reserved for LAN

IRQ11 : Serial port 4

IRQ12 : spare (PS/2 mouse)

IRQ13 : Math. coprocessor

IRQ14 : Hard disk adapter

IRQ15 : spare (Watchdog Timer)
