1.1 Introduction

The AHP-2173 operator panel is an Intel® Atom™ D2550 1.86 GHz processor computer that is designed to serve as a human machine interface (HMI). It is a PC-based system with 17" color TFT LCD display, onboard Ethernet controller, multi-COM port interfaces and

an audio controller. With a built-in CFast™ socket, the AHP-2173 is as compact and user friendly as a multi-function computer. In

addition, its "fit anywhere" design makes it very flexible and able to be used in many different kinds of installations. It can be Panel/ VESA 100/ wall mounted.

For system integrators, this simple, complete, compact and highly integrated system let you easily build an operator panel into your applications. Common industrial applications include factory automation systems, precision machinery, and production process control. It is also suitable for many non-industrial applications, including vending machine, and car park automation. Our operator panel is a reliable, cost-effective solution to your application's processing requirements.

BIOS Setup

Chapter 3 AMI BIOS Setup 3-1

Touch Panel PC

AHP- 217 3

3.1 System Test and Initialization

These routines test and initialize board hardware. If the routines

encounter an error during the tests, you will either hear a few short

beeps or see an error message on the screen. There are two kinds

of errors: fatal and non-fatal. The system can usually continue the

boot up sequence with non-fatal errors.

System configuration verification

These routines check the current system configuration against the

values stored in the CMOS memory. If they do not match, the

program outputs an error message. You will then need to run the

BIOS setup program to set the configuration information in memory.

There are three situations in which you will need to change the

CMOS settings:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The CMOS memory has lost power and the configuration information has been erased.

The AHP-2173 CMOS memory has an integral lithium battery backup for data retention. However, you will need to replace the complete unit when it finally runs down.

Chapter 3 AMI BIOS Setup 3-2

3.2 AMI BIOS Setup

AMI BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed CMOS RAM so that it retains the Setup information when the power is turned off.

Entering Setup

Power on the computer and press <Del> or <F2> immediately. This will allow you to enter Setup.

A.1 Programming

AHP-2173 utilizes ITE 8783 chipset as its watchdog timer controller. Below are the procedures to complete its configuration and the AAEON initial watchdog timer program is also attached based on which you can develop customized program to fit your application.

Configuring Sequence Description

After the hardware reset or power-on reset, the ITE 8783 enters the normal mode with all logical devices disabled except

KBC. The initial state (enable bit ) of this logical device (KBC) is determined by the state of pin 121 (DTR1#) at the falling edge of the system reset during power-on reset.

Appendix A Programming the Watchdog Timer A-2

AHP- 2173

There are three steps to complete the configuration setup: (1) Enter the MB PnP Mode; (2) Modify the data of configuration registers; (3) Exit the MB PnP Mode. Undesired result may occur if the MB PnP Mode is not exited normally.

(1) Enter the MB PnP Mode

To enter the MB PnP Mode, four special I/O write operations are to be performed during Wait for Key state. To ensure the initial state of the key-check logic, it is necessary to perform four write opera-tions to the Special Address port (2EH). Two different enter keys are provided to select configuration ports (2Eh/2Fh) of the next step.

(2) Modify the Data of the Registers

All configuration registers can be accessed after entering the MB PnP Mode. Before accessing a selected register, the content of Index 07h must be changed to the LDN to which the register belongs, except some Global registers.

(3) Exit the MB PnP Mode

Set bit 1 of the configure control register (Index=02h) to 1 to exit the MB PnP Mode.

WatchDog Timer Configuration Registers

Configure Control (Index=02h)

This register is write only. Its values are not sticky; that is to say, a hardware reset will automatically clear the bits, and does not require the software to clear them.
