3.18 Digital I/O

One characteristic of digital circuit is its fast response to high or low signal. This kind of response is highly needed for harsh and critical industrial operating environment. That’s why we design 4-bit digital inputs and 4-bit digital outputs on NOVA-7820.

Digital Input and Output, generally, are control signals. You can use these signals to control external devices that needs On/Off circuit or TTL devices. We provide "BIOS Call" for DIO reading.

4. AMI BIOS Setup

4.1 Introduction

This chapter discusses the Setup program built into the BIOS. which allows users to configure the system. This configuration is then st ored in battery-backed CMOS RAM so that Setup information is retained whilst the power is off.

4.2 Starting Setup

The BIOS is immediately active when you turn on the computer. While the BIOS is activated, the Setup program can be entered in one of two ways: By pressing <Del> immediately after switching the system on, or by pressing the <Del> key when the following message appears briefly at the bottom of the screen during the POST (Power On Self-Test).

Press DEL to run SETUP.

Primary/Secondary Master/Slave LBA Mode

LBA (Logical Block Addressing) is a new IDE HDD access method to develop to overcome the 528-megabyte capacity bottleneck. If your IDE hard disk capacity is greater than 528MB, AMIBIOS can enable this LBA mode feature. The option is only for Primary Master IDE LBA mode.

If your hard disk drive supports IDE block transfer mode, enable this option for a faster IDE hard disk drive transfer rate. The option is only for Primary Master Block mode.

Primary/Secondary Master/Slave PIO Mode

This option enables Primary Master IDE PIO mode on the IDE, w hich can set proper cycle timings. The cycle timing between the IDE PIO mode value and IDE cycle timing is shown below : Mode 0 -> Timing ( 600ns ) Mode 1 -> Timing ( 383ns ) Mode 2 -> Timing ( 240ns ) Mode 3 -> Timing ( 180ns ) Mode 4 -> Timing ( 120ns ) Mode 5 -> Timing ( 60ns )

Appendix A Watchdog Timer

Watchdog Timer is a device to ensure that standalone systems can always recover from catastrophic conditions that cause CPU crash which may be caused by external EMI or a software bug. When the CPU stops working normally, hardware on the board will issue a time-out signal.

A BIOS function call (INT 15H) is used to control Watchdog Timer:

INT 15H:

AH – 6FH

Sub-function:

AL – 2 : Set the Watchdog Timer’s period BL: Time-out value(the time unit--second, is

dependent on the item “Watchdog Timer unit (selected in BIOS setup).

You have to call sub-function 2 to set the time-out period of Watchdog Timer first. If the time-out value is not zero, Watchdog Timer will start counting down. When the timer value reaches zero, the system will reset. To ensure reset condition does not occur, Watchdog Timer must be periodically refreshed by calling subfunction 2. However the Watchdog timer will be disabled if you set the time-out value to be z ero.

A tolerance of at least 10% must be maintained to avoid unknown routines within the operating system (DOS), such as disk I/O that can be very time-consuming.

Note: When exiting a program, it is necessary to disable Watchdog Timer, otherwise the system will reset.

Example program:

; INITIAL TIMER PERIOD COUNTER ;

W_LOOP: MOV AX, 6F02H ;setting the time-out value

MOV BL, 30 ;time-out value is 48 seconds

INT 15H ; ; ADD YOUR APPLICATION PROGRAM HERE ; CMP EXIT_AP, 1 ;is your application over? JNE W_LOOP ;No, restart your application

MOV AX, 6F02H ;disable Watchdog Timer MOV BL, 0 ; INT 15H ; ; EXIT

Appendix B Digital I/O

One characteristic of digital circuit is its fast response to high or low signal. This kind of response is highly needed for harsh and critical industrial operating environment. That’s why we design 4-bit digital inputs and 4-bit digital outputs on the NOVA-7820. Digital Input and Output, generally, are control signals. You can use these signals to control external devices that needs On/Off circuit or TTL devices. You can read or write data to the selected address to enable the function of digital IO.

A BIOS function call (INT 15H) is used to control Watchdog Timer: INT 15H:

AH – 6FH

Sub-function:

AL – 8: Set the Digital port is INPUT AL : Digital I/O input value

Example program:

MOV AX, 6F08H ;setting the Digital port is input INT 15H ;

AL low byte = value

AH – 6FH

Sub-function:

AL – 9: Set the Digital port is OUTPUT BL : Digital I/O output value

Example program:

MOV AX, 6F09H ;setting the Digital port is output MOV BL, 09H ;Digital value is 09H INT 15H ;

Digital Output is 1001b

Appendix D How to Use Wake-up Function

NOVA-7820 provides two kind of Wake up Function. This page describes how to use Modem Wake-Up and LAN Wake-Up function. Wake-Up function is working while you use ATX power supply.

Wake-Up By Ring: You must set the option Power On By Ring of CMOS SETUP to be enabled. The ATX power supply will be switched on when there is a ring signal detected on pin “RI” of serial port.

Wake-Up On LAN: When your computer is in power-down status, you can see LAN Link/ Active LED is flashing. This status indicates that the LAN chip has entered standby mode and waits for Wake-Up signal. You can use other computers to wake up your computer by sending ID to it.

ID: ID is the address of your system LAN. Every LAN chip has a factory, set ID, which you can find it from network information in WINDOWS.

The format of ID is xxxxxxxxxxxx Example ID: 009027388320

Appendix E How to Use Video-in Function

NOVA-7820 provides users to capture live video from video source such as the CCTV camera. NOVA-7820 has four video input channels for surveillance systems.

Driver Installation: Taking the advantage of IEI driver installation program makes the driver installation an easy job.

Steps:

1. Insert the IEI Driver CD (4).

2. The window will display the menu of IEI Driver CD. Click “IVC Series”.

3. Click “IVC-100/100G/200/200G”.
