0.7STATIC 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:

zIntroduction

zPacking List

zFeatures

1.1INTRODUCTION

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:

zMicroprocessor

zDMA Controller

zKeyboard Controller

zInterrupt Controller

zReal-Time Clock and Non-Volatile RAM

zTimer

zSerial Port

zParallel Port

2.1MICROPROCESSOR

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:

Channel 0: Spare

Channel 4: Cascade for controller 1

Channel 1: IBM SDLC

Channel 3: Spare

Channel 7: Spare

Table 2-1 DMA Channel Controller

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.

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.

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.

Figure 3-1 AR-B1376 Jumpers & Connectors Placement

3-1

AR-B1375/AR-B1376 User’s Guide

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.
