1. INTRODUCTION

Welcome to the AR-B1631 Single Board Computer. The AR-B1631 board Low power GX3 series Processors with
the advanced chipset CS5536(CS5535). This product is designed for the system manufacturers, integrators, or
VARs that want to provide all the performance, reliability, and quality at a reasonable price.

In addition, the AR-B1631 provides on chip VGA. The VGA, which provides up to True Color (32 bit) 1024x768, or
High Color (16 bit) 1280x1024 resolution. The VGA memory is share main memory (2M, 4M, or 8M). AR-B1631
also has 18-bit LVDS function in the system.

The AR-B1631 is loaded with special on-board features that rival full-size systems. It has one network controller on
board, uses Realtek RTL8100BL LAN controller, a fully integrated 10/100BASE-TX solution with high performance
networking functions. Supports Compact Flash™ Type II interface. Plus optional support for AC97 sound with
CD-input. The AR-B1631 also includes one 200-pin SO-DIMM DDR sockets for up to 512 MB total on-board
memory. The AR-B1631 has four on-board serial ports; COM1 with RS232C,COM2, COM3 and COM4 with
RS232C, 4 USB ports, and tough industrial grade construction. All these features make the AR-B1631 a very
"system integrator friendly" solution, perfect for handling applications in the harshest unmann ed environments.

2.2 SYSTEM SETTINGS

Jumper pins allow you to set specific system parameters. Set them by changing the pin location of the 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 needl e-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-B1631 jumper pins, and the factory-default settings.

CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a
grounded wrist strap or touch an exposed metal pa rt of the system unit chassi s. The static discharges
from your fingers can permanently damage electronic components.

NOTE 1：

For using both of Hard Disk And Compact Flash, y ou have to use the ATA33 IDE
cable.
IF you want to use ATA66/100 mode with Hard Disk, you must put jumper on
JP6 and use the special IDE cable.

The cable is like below：

IDE HOST

In usual ATA66/100 cable the
Pin 34 at host side is defined
as CABLE ID and connected
to ground.

In special cable, the Pin 34 is
defined as PDIAG. And cannot
connect to ground

NOTE 2：

USB connectors (USB1 & USB2) and USB Pin headers cannot use together. And
if you want to use USB connectors, you must take the USB cable on Pin Header.

AR-B1631 User’s Guide

In usual ATA66/100 cable, the Pin 34 between host and
device side are disconnected.

The special cable must connect this PDIAG signal from host
side to device side.

4. BIOS CONSOLE

This chapter describes the AR-B1631 BIOS menu displays and explains how to perform common tasks needed to
get up and running, and presents detailed explanations of the eleme nts found in each of the BIOS menus. The
following topics are covered:

 BIOS Setup Overview
 Advanced CMOS Setup
 Perip heral Setup
 Boot
 BIOS Exit

4.1 BIOS SETUP OVERVIEW

The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the
ISA bus and con nected 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 is turned on, the BIOS will perform diagnosti cs on 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 select the option and configure the
functions.

Setup Main Menu

The <Main> option allows you to record some basic system hardware configuration and set the system clock
and error handling. If the CPU board is already installed in a working system, you will not need to select this
option anymore.

Date & Time Setup

Highlight the <Date> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current

12

AR-B1631 User’s Guide

date. Follow the month, day and year format.
Highlight the <Time> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current
date. Follow the hour, minute and second format.

Hard Disk Setup

The BIOS supports 2 types for user settings, The BIOS supports <Pri Master> and <Pri Slave>, <Sec
Master> and <Sec Slave> so the user can install up to two hard disks.
