Configuration

This chapter gives background information on the PCA-6143P. It then shows you how to configure the card to match your application and prepare it for installation into your PC.

Sections include:

• Card specifications

• Locating components

• Safety precautions

• Configuration – Jumper settings

Experienced users can skip to the Quick Start section on page 39.

Chapter 1 Hardware Configuration 1

Introduction

The half-size PCA-6143P comes equipped with either an 80486SX25, 80486SX-33, 80486DX-33, 80486DX2-50 or 80486DX2-66 CPU. Also included on-board are one serial RS-232 port, one serial RS-232/422/485 port, an enhanced bi-directional parallel port, an IDE hard disk drive interface, a floppy disk controller and a watchdog timer. The watchdog timer ensures that the CPU will be reset if it stops due to a program or EMI problem, allowing the PCA-6143P to be used in stand-alone systems or unattended environments. The PCA6143P’s industrial-grade construction ensures continuous, reliable operation in harsh industrial environments at temperatures up to 140oF (60oC).

We designed the PCA-6143P with SBC (Single Board Computer) applications in mind. It incorporates a single-voltage power supply (+5 V) and a connector for PC/104 modules (Flat-panel/CRT VGA controller or Flash/RAM/ROM disk). A built-in Flash/ROM disk emulates a floppy disk drive of up to 1.44 MB capacity. It emulates the 1st, 2nd, 3rd or 4th DOS drive, depending on the physical disks installed and the DOS version. See Appendix A for details.

Built using CMOS technology, the PCA-6143P consumes very little power. Its two SIMM (Single In-line Memory Module) DRAM sockets accept 1 MB, 4 MB or 16MB SIMM modules for total onboard memory of 1 to 32 MB.

You can also use this 8-layer CPU card to transform any system into a 32-bit 486 compatible computer, its all-in-one configuration freeingup valuable expansion slots. Its highly compact form and numerous features make it an ideal cost/performance solution for high-end commercial and industrial applications where high CPU speed and low mean-time-to-repair are critical.

SIMM memory modules

On the left end of the card (away from the mounting bracket) are the two SIMM (Single In-line Memory Module) sockets which hold the card’s DRAM memory. If you ordered DRAM SIMMs along with your card, the SIMMs may already be installed. If not, you should install them as described in Appendix C.

Flash/RAM/ROM disk

At the right of the card are three 32-pin sockets which hold the memory chips for the card's Flash/RAM/ROM disk. Instructions for installing memory chips appear in Appendix A.

Chapter 1 Hardware Configuration 7

Safety precautions

Follow these simple precautions to protect yourself from harm and your PC from damage.

1. To avoid electric shock always disconnect the power from your PC

chassis before you work on it. Don’t touch any components of the CPU card or other cards while the PC is on.

2. Disconnect power before making any configuration changes. The

sudden rush of power as you connect a jumper or install a card may damage sensitive electronic components.

3. Always ground yourself to remove any static charge before you

touch your CPU card. Be particularly careful not to touch the chip connectors. Modern integrated electronic devices, especially CPUs and memory chips, are extremely sensitive to static electric discharges and fields. Keep the card in its anti-static packaging when it is not installed in the PC and place it on a static dissipative mat when you are working on it. Wear a grounding wrist strap for continuous protection.

Jumper settings

This section tells how to set the jumpers to configure your card. It gives the card default configuration and your options for each jumper. After you set the jumpers and install the card, you will also need to run the BIOS Setup program (discussed in Chapter 5) to configure the serial port addresses, floppy/hard disk drive types and system operating parameters. Connections, such as hard-disk cables, appear in Chapter 3.

Card default setting

We set the card’s jumpers at the factory for the most popular configuration. If this configuration matches your needs, you may not need to change the jumpers at all. The default configuration is as follows:

• Watchdog invokes system reset • Color display is attached

• Parallel port IRQ7, DRQ1, DACK1 • Bypass POST (JP14)

8 PCA-6143P User's Manual

How to set jumpers

You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you would connect either pins 1 and 2 or 2 and 3.

If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representative before you make any changes.

Display type (JP15)

This jumper sets the display adapter type attached to your card. If you are using a monochrome LCD or EL screen which uses a CGA, EGA, VGA or other color display adapter, set JP15 to color.

JP15 Setting

Open Monochrome Closed (default) Color

Watchdog timer  system reset/IRQ15 (JP8)

When the watchdog timer activates (CPU processing has come to a

halt), it can reset the system or generate an interrupt on IRQ15. Set jumper JP8 as shown in the following table:

CHAPTER

Installation

This chapter gives guidelines for installing your CPU card into an PC chassis with an A T-compatible passive backplane. For specific instructions, consult the user’s manual for your chassis.

Before you begin, double check the jumper settings for the card (described in Chapter 1). This could save you a lot of troubleshooting time later. If you are not sure about the proper setting, contact your local distributor or sales representative.

Chapter 2 Installation 11

Warning! Disconnect all power from the chassis before you

install the CPU card. Unplug the power cord from the wall, don’t just turn off the power switch. If you are not sure what to do, take the job to an experienced professional.

Caution! The electronic components on this CPU card are

very sensitive to static electric charges. Use a grounding wrist strap to remove all static electricity before you touch any components. Place all components on a static-dissipative mat or in a static-shielded bag when they are not in the chassis.

Install your CPU card as follows:

1. Remove power from the chassis and disconnect all power cords. Follow all power-down procedures outlined in your chassis user’s manual.

2. Remove the chassis cover, then detach the card hold-down bracket. This bracket stretches across the top of each circuit card to hold it securely in place.

3. Locate a free slot in the chassis. You can use any 16-bit (double connector) slot. We suggest that you leave the maximum amount of space between boards to improve cooling.

4. You may need to remove a block-off cover at the end of the slot. Unscrew the cover and save the screw for use in Step 6.

5. Align the card square with the card-end guide slot and parallel to the connector. Slide the card carefully into the connector.

6. Make sure the card is completely seated in the connector. Screw the card I/O bracket to the case.

After you have installed the CPU card, you will need to attach the connecting cables as described in the following chapter. Replace the card hold-down bracket you removed in Step 2, replace the chassis cover and power-up your system.

Dimensions for SBC (Single Board Computer) installation appear in Chapter 1 (page 10).

CHAPTER

Connecting

peripherals

This chapter tells how to connect peripherals, switches and indicators to the PCA-6143P board. You can access most of the connectors from at the top of the board while it is installed in the chassis. If you have a number of cards installed, or your chassis is very tight, you may need to partially remove the card to make all the connections. When everything is done, finish installing the card as described in Chapter 2.

Chapter 3 Connecting peripherals 13

The following table lists the connectors on the PCA-6143P. See Chapter 1 (page 5) for help with locating the connectors.

Component Label Page

HDD (IDE) connector CN1 16 FDD connector CN2 15 Parallel port CN3 16 PC/104 connector CN4, CN5 61 Keyboard connectors J1, J3 17 Reset switch connector JP7 17 Power LED and keylock connector JP9 18 HDD LED connector JP1 18 Turbo switch connector JP12 18 Turbo LED connector JP13 19 External speaker connector JP10 19 SBC power connector J2 19 RS-232 serial port COM1 20 RS-232/422/485 serial port COM2 21

The following sections tell how to make each connection. In most cases you will simply need to connect a standard cable. If you need to make your own cables, you can find pin assignments for the more complicated connectors in Appendix D.

Warning! Always completely disconnect the power cord

from your chassis whenever you are working on it. Do not make connections while the power is on, sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis.

Caution! Always ground yourself to remove any static

charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis.

14 PCA-6143P User's Manual

Floppy drive connections

You can attach up to two floppy disk drives to the PCA-6143P's on-board controller. You can use any combination of 5.25" (360 KB and 1.2 MB) and/or 3.5" (720 KB and 1.44 MB) drives.

The card comes with a 34-pin daisy-chain drive connector cable. On one end of the cable is a 34-pin flat-cable connector. On the other end are two sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable connector (usually used for 3.5" drives) and a printed-circuit-board connector (usually used for

5.25" drives). You can use only one connector in each set. The set on the end (after the twist in the cable) connects to the A: floppy. The set in the middle connects to the B: floppy.

Attach the single 34-pin flat-cable connector to CN2 on the CPU card. For help finding the connector, see Chapter 1 (page 5). Wire number 1 on the cable is red or blue, the other wires are gray. Make sure that the red wire corresponds to pin one on the connector (on the right side).

Connect the A: floppy drive to the connector set on the other end of the cable. If you are connecting a 5.25" floppy drive, line up the slot in the printed-circuit-board (golden fingers) with the blockedoff part of the cable connector.

If you are connecting a 3.5" floppy drive, you may have trouble determining which pin is number one. Look for a number printed on the circuit board indicating pin number one. Also, the connector on the floppy drive connector may have a slot. When the slot is up, pin number one should be on the right. Check the documentation that came with the drive for more information.

Next, if required, connect the B: floppy drive to the connectors in the middle of the cable as described above.

If you need to make your own cable, you can find the pin assignments for the card’s connector in Appendix D.

Chapter 3 Connecting peripherals 15

IDE hard drive connections

You can attach two IDE (Integrated Device Electronics) hard disk drives to the PCA-6143P's internal controller. The card comes with a 40-pin flat-cable piggyback cable. This cable has three identical 40-pin flat-cable connectors.

Wire number 1 on the cable is red or blue, the other wires are gray. Connect one end to connector CN1 on the CPU card. Make sure that the red wire corresponds to pin one on the connector (on the right side). See Chapter 1 for help finding the connector.

Unlike floppy drives, IDE hard drives can connect in either position on the cable. If you install two drives, you will need to set one as the master and one as the slave. You do this using jumpers on the drives. If you use just one drive, you should set it as the master. See the documentation that came with your drive for more information.

Connect the first hard drive to the other end of the cable. Wire one on the cable should also connect to pin one on the hard drive connector. You may have difficulty determining the pin number. Look for a number printed on the drive circuit board. Check the documentation that came with the drive for more information.

Connect a second drive as described above. If you need to make your own cable, you can find the pin assign-

ments for the card’s connector in Appendix D.

Parallel Port

You would normally use the parallel port to connect the card to a printer. The PCA-6143P includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN3. The CPU card comes with an adapter cable which lets you use a traditional DB-25 connector. The cable has a 26-pin connector on one end

16 PCA-6143P User's Manual

and a DB-25 connector on the other, mounted on a retaining bracket. The bracket installs at the end of an empty slot in your chassis, giving you access to the connector.

To install the bracket find an empty slot in your chassis. Unscrew the plate that covers the end of the slot. Screw in the bracket in place of the plate. Next, attach the flat-cable connector to connector CN3 on the CPU card. Wire one of the cable is red or blue, the other wires are gray. Make sure that wire one connects to pin one of CN3. Pin one is on the right side of CN3. For help finding the connector, refer to Chapter 1 (page 5).

The pin assignments for the connector appear in Appendix D.

Keyboard connectors

The PCA-6143P board provides two keyboard connectors. A 5-pin connector (J1) supports passive backplane applications. A second 6-pin mini-DIN connector (J3) on the card mounting bracket supports single-board-computer applications. The card comes with an adapter to convert from the 6-pin mini-DIN connector to a standard DIN connector.

If you need to make your own adapter cable, you can find the pin assignments in Appendix D.

External switches and indicators

Next you may want to install external switches to monitor and control your CPU card. These features are completely optional — install them only if you need them.

Reset switch (JP7)

You can connect an external switch to easily reset your computer. This switch restarts your computer as if you had turned off the power then turned it back on. Install the switch so that it closes the two pins of JP7 when pressed (normally-open switch).

Chapter 3 Connecting peripherals 17

Power LED and keylock (JP9)

You can connect an LED to indicate when the CPU card is on. Pin 1 of JP9 supplies power to the LED and Pin 3 is the ground. For help finding JP9, refer to Chapter 1 (page 5).

You can use a switch (or a lock) to disable the keyboard. In this state the PC will not respond to any input. This is useful if you don’t want anyone to change or stop a running program. Simply connect the switch between Pins 4 and 5 of JP9. The pin assignments for JP9 appear in the following table:

Power LED and keylock (JP9)

Pin Function

1LED Power (+5 V) 2No Connection 3Ground 4Keyboard lock 5Ground

Hard disk drive LED (JP1)

You can connect a LED to connector JP1 to indicate when the HDD is active. The pin on the top is positive.

Turbo switch (JP12)

You can connect a switch across the pins of jumper JP12 to change the CPU between Turbo and non-Turbo mode. When you close (short) the pins, the CPU card operates at full speed. When you leave the pins open, the card operates at slow speed for compatibility with older software.

You can also switch the CPU back and forth between Turbo mode and non-Turbo mode using the keyboard, but only when jumper JP12 is open. When jumper JP12 is closed, the CPU is fixed in Turbo mode. To switch into Turbo mode from the keyboard simultaneously press the Ctrl, Alt and keypad plus (+) keys. To switch into non-Turbo mode press the Ctrl, Alt and keypad minus (-) keys.

Serial Ports

The PCA-6143P offers two serial ports: one RS-232 and one RS-232/422/485. These ports let you connect to serial devices (a mouse, printers, etc.) or a communication network.

You can select the address for each port (3F8H [COM1], 2F8H [COM2] or 3E8H) or disable it, through the BIOS Advanced Setup program, covered in Chapter 5.

The card mounting bracket holds the serial port connectors. This lets you connect and disconnect cables after you install the card. The DB-9 connector on the top of the bracket is the RS-232 port. The second DB-9 connector is the RS-232/422/485 port. The following sections tell how to make RS-232 and RS-232/422/485 connections.

RS-232 connections

Different devices implement the RS-232 standard in different ways. If you are having problems with a serial device, be sure to check the pin assignments for the connector. The following table shows the pin assignments for the card's RS-232 port:

RS-232/422/485 serial port connections

RS-422 is commonly used for two-way communication between two devices, whereas RS-485 is used for communication between a single master and a network of slave modules.

Before you use the RS-232/422/485 port, you will need to select RS-232, RS-422 (the default) or RS-485 mode. Set jumpers JP20, 22, 25, 26, 27, 28, 29 and 30 according to the following table:

å RS-422 signal wiring

RS-422 is used for long-distance point-to-point connections. RS422 originally used four wires for one-way communication (with devices such as display terminals or printers) but was later adopted by industry for simultaneous two-way communication by doubling the number of wires.

Each pin on the first device connects to a corresponding device on the second. Flow control lines manage the communication. The following table shows pin connections:

Computer A Computer B

å RS-485 signal wiring

In a typical RS-485 application the host device requests data from a slave module then listens for the response. The host transmits and receives data on the same pair of wires. Software handles the flow control; no other wires are needed.

Pin assignments appear in the following table. Pins 1 and 4 share the Data+ wire. Pins 2 and 3 share the Data- wire.

Now that you have made all the required external connections, you can close up your chassis (as described in Chapter 2). If you are installing any other cards, do it now. You can then power up your system as described in the next chapter.

Chapter 3 Connecting peripherals 23

24 PCA-6143P User's Manual

CHAPTER

Power-up

After you have set the jumpers (Chapter 1), installed SIMMs (Appendix C), installed the card (Chapter 2) and made all external connections (Chapter 3), you are ready to power-up your system.

Chapter 4 Power-up 25

Follow the startup procedure outlined in the manual for your chassis.

When you start your system, the BIOS will test the hardware and check the system configuration against the values stored in its CMOS memory.

Since this is the first time you are starting up, the BIOS will display an error message stating that the configuration does not match the stored values. You should then run the BIOS setup program as described in Chapter 5.

If the BIOS hardware diagnostic tests fail, you may see an error message on the screen describing the problem. If the BIOS found a problem early in the tests, you will need to determine the BIOS POST (Power On Self Test) results by counting beeps or using a POST card. See Appendix F for details.

The most common source of problems is incorrect jumper settings. Double check your settings (Chapter 1) and restart the system. If the system still has problems, see Appendix E, Maintenance and troubleshooting.

There are three methods you can use to restart your system after it is turned on:

1. Switch the power off, then on again

2. Reboot the system. Using the keyboard, simultaneously press the CTL, ALT and DEL keys

3. Depress the optional reset switch

Use of each of these methods will erase data from the system RAM memory. If you can, save any data stored in memory to a hard or floppy disk before you reset your system.

26 PCA-6143P User's Manual

CHAPTER

BIOS diagnostics

and SETUP

This chapter describes the card’s diagnostic tests and how to set BIOS configuration data. BIOS POST (Power On Self T est) test codes appear in Appendix F.

Chapter 5 BIOS diagnostics and setup 27

POST (Power On Self Tests)

Whenever you start up your system, the CPU card runs a series of programs stored in an on-board ROM chip. These programs are divided into two stages:

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. Non-fatal error messages usually appear on the screen along with the following instructions:

press <F1> to RESUME

Write down the message and press the F1 key to continue the bootup sequence. Non-fatal error messages appear in Appendix F.

If the routines encounter a fatal error, they will stop the tests and output a message indicating which test failed. If the fatal error comes before the screen device initializes, the card will indicate the error code through a series of beeps. Error beep codes also appear in Appendix F .

System configuration verification

These routines check the current system configuration against the values stored in the card’s CMOS memory. If they don’t match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory.

28 PCA-6143P User's Manual

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 PCA-6143P’s CMOS memory has integral lithium battery backup. The battery backup should last ten years in normal service, but when it finally runs down, you will need to replace the complete unit. Contact your sales representative or distributor for details.

Running the setup program

Normally, the only routine visible on the screen will be the memory test. The following figure shows the screen as it appears while the tests are occurring.

Power On Self Tests

A line of reference codes appears at the bottom left of the screen. These codes identify the options installed in the AMI BIOS. If you have a problem with your system, make a note of these codes before you contact your dealer for technical support.

To “freeze” the screen so that you can write down the codes, power-on the system and hold down a key on the keyboard. This will cause a “Keyboard Error” message to appear on the screen and the system will wait for you to press the <F1> key. After you

Chapter 5 BIOS diagnostics and setup 29

copy down the line, you can then press <F1> to continue the boot procedure. After the POST routines are complete, the following message appears:

Hit <DEL> if you want to run SETUP

Press the <DEL> key to access the BIOS setup program. The BIOS Setup screen will then appear.

BIOS Setup Main Menu

You use the following keys to control the BIOS SETUP program:

ESC: Exit to previous screen ARROW KEYS: Moves the cursor to highlight the desired

configuration option

PAGEUP/PAGEDOWN/CTRL-PAGEUP/CTRL-PAGE-

DOWN:

Cycles through the configuration options for the highlighted feature. If there are less than ten available options, the CtrlPageUp and Ctrl-PageDown keys function the same as the PageUp and PageDown keys.

F1: Displays a help screen for selected feature. F2/F3: Changes background and foreground colors. F5: Retrieves the values which were resident when the current

setup session was started. These values will be CMOS values if the CMOS was uncorrupted at the start of the session, or they will be the BIOS Setup default values.

F6: Loads all features in the Advanced CMOS Setup with the

BIOS Setup defaults.

F7: Loads all features in the Advanced CMOS Setup with the

Power-On defaults (the values in the CMOS when the system was started).

F10: Saves all changed made to Setup and exits program.

Flash/ROM disk

APPENDIX

Appendix A Flash/ROM disk 47

The PCA-6143P features an internal Flash/ROM disk drive. This drive emulates a floppy disk drive by using solid-state memory chips (Flash or EPROM) to store programs and data instead of the magnetic particles on the mechanical drive’s disk. The Flash/ROM disk offers much faster access times than a floppy or hard disk and greatly increased reliability in harsh environments.

The Flash/ROM disk works by modifying the BIOS INT-13 disk I/O routine on boot-up. The routine then translates read and write commands to the disk so that they will correctly access the memory chips. You don’t need any special drivers. You simply set the drive to act as a DOS drive (e. g. A:, B:, C: or D: - 1st, 2nd, 3rd or 4th floppy disks) and use standard DOS commands (COPY, DIR, etc.) to manipulate your data.

Before you use the Flash/ROM disk, you will need to enable it with the BIOS Advanced Setup Program, discussed in Chapter 5.

Memory devices

The Flash/RAM/ROM disk supports the following memory devices, or their equivalents:

• 27C010 128 KB x 8 EPROM

• 27C040 512 KB x 8 EPROM

• 28F010 128 KB x 8 +12 V Flash Memory (AMD/INTEL)

• 29C010 128 KB x 8 +5 V Flash Memory (ATMEL only)

• 29C040 512 KB x 8 +5 V Flash Memory (ATMEL only) If you use EPROM, files on the disk are read only . You will need

an external programmer to load your program and data files on the EPROMs.

If you use +5 V Flash memories (29C010 or 29C040) for the solid state disk, you can read or write data just like a floppy disk; you need not use an external programmer. If you use +12 V Flash memories (28F010) you will still need an external programmer to write data.

48 PCA-6143P User's Manual

Drive capacity

The size of the emulated drive depends on the size and number of the chips you install. For example, if you install three 512 KB chips, you will have 3 x 512 KB = 1.536 MB, equivalent to a 1.44 MB floppy.

You will need to set jumpers JP19, JP23 and JP24 to match the type (Flash, RAM or ROM) and size (128 KB or 512 KB) of the devices you use. All the devices must be the same type and size.

The following tables shows the size and number of devices you will need for each size emulated disk. It also shows the corresponding settings of jumpers JP19, JP23(Flash/RAM/ROM) and JP24 (128 KB/512 KB).

Drive configuration

Before you activate the Flash/RAM/ROM drive (using the BIOS Advanced Setup program), you will need to set the drive's I/O and memory addresses to avoid conflicts with other plug-in cards. You will also need to set the DOS drive designation to be used by the Flash/RAM/ROM drive. DIP switch SW1 controls each of these settings, as described in the following sections:

Appendix A Flash/ROM disk 49

åI/O address selection (SW1)

Positions 1 and 2 on DIP switch SW1 control the disk's I/O address.

Position 1 Position 2 I/O address (HEX)

Off Off Disabled Off On 200-201 On Off 240-241 On On 280-281

Memory address selection (SW1)

Positions 3 and 4 on SW1 control the Flash/ROM disk’s memory address. If you select "Disabled", the disk will not function.

Position 3 Position 4 Memor y address (HEX)

Off Off Disabled Off On D2000 to D3FFF On Off D6000 to D7FFF On On DA000 to DBFFF

åDrive emulated (SW1)

Positions 5 and 6 of SW1 control the DOS drive emulated by the Flash/RAM/ROM disk: 1st, 2nd, 3rd or 4th.

Position 5 Position 6 Drive

Off Off 4th Off On 3rd On Off 2nd On On 1st

The actual drive letter assigned by DOS to the Flash/RAM/ROM disk depends on the floppy or hard disks installed in the system and the DOS version.

50 PCA-6143P User's Manual

Drive Selection

DOS 5.0 (and later)

Floppy disks

The Flash/ROM disk will replace the corresponding floppy disk. For example, if you have a single floppy disk (drive A:) and assign the Flash/ROM disk to be the 1st drive (both switches 5 and 6 are on), any drive operations directed at drive A: will go to the Flash/ ROM disk. This floppy drive will then be assigned the next free drive designation. The example below illustrates this.

Hard disks

The Flash/ROM disk will not replace corresponding hard disks. Instead, DOS will assign the Flash/ROM disk to the next free drive designation. For example, if you have a single hard disk (drive C:) and assign the Flash/ROM disk to be the 3rd drive (switch 5 on, switch 6 off), the Flash/ROM drive will become drive D:. If you have two hard disks, the Flash/ROM drive will become drive E:.

Example 1

You install the Flash/ROM disk as drive A: (both switches 5 and 6 are on).

Booting from the Flash/RAM/ROM disk

If you wish to have the system boot from the Flash/RAM/ROM disk, simply set positions 5 and 6 on SW1 for the 1st FDD. Copy your application files to the disk along with the standard system files required to boot (command.com, io.sys, autoexec.bat, etc). The next time you start the system, it will boot from the solid state disk.

Inserting memory devices

After you’ve set all the jumpers and switches on the PCA-6143P, insert the appropriate memory devices into the card’s sockets. Remember that you will need to program EPROMs before you insert them.

1. Make sure that the pins of the memory chips are perpendicular to the case and both rows are parallel to each other. Many times the chips come with the pins spread out slightly. Place the chip on a table top and carefully bend each line of pins together until they point directly down.

2. Insert each chip. Align the chips so their pins are perpendicular to the connector and the semicircular notch on the end of the chip matches the notch on the end of the socket. There will probably be a gap between the chip body and the socket when it is fully seated – do not push too hard!

52 PCA-6143P User's Manual

Formatting the Solid State disk

If you use Flash memory or SRAM, it is advisable to format the Flash/SRAM disk before copying files to it. The DOS command is as follows:

FORMAT drv: /U ...

where drv = solid state disk drive A, B, C etc.

File copy utility

The utility program COOKROM.EXE, included on the card's utility disk, splits the files on a diskette into a series of binary files. You can then use an external programmer to copy the files to EPROM or +12 V Flash memory chips. It produces up to three files, depending on the size of the source files.

Using a memory manager

(EMM386.EXE)

If you are using an extended or expanded memory manager (such as EMM386 or QEMM386), you will need to configure it to avoid the addresses used by the Flash/RAM/ROM disk (set by positions 1 and 2 of SW1). Otherwise, the memory manager will attempt to use these addresses, causing unreliable operation.

For example, the line in your CONFIG.SYS file that invokes EMM386, the DOS memory manager, might be the following:

DEVICE=EMM386.SYS X=D600-D7FF

This excludes a 8 KB range for the card from D6000 to D7FFF (the default addresses).

If you are using expanded memory, you will need to make sure that the memory manager is not putting the page frame in the disk's addresses. For example,

DEVICE=EMM386.EXE X=D600-D7FF FRAME = D800

You should also make sure that the disk's memory address is not shadowed in the BIOS.

CHAPTER

Programming the

watchdog timer

The PCA-6143P is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial stand-alone and unmanned environments.

Appendix B Programming the watchdog timer 55

Programming the watchdog timer

If you decide to program the watchdog timer, you must write a program which reads I/O port address 443 (hex) at regular intervals. The first time your program reads the port, it enables the watchdog timer. After that your program must read the port at time intervals less than 2.0 seconds (as set in the BIOS), otherwise the watchdog timer will activate and reset the CPU or generate an interrupt on IRQ15. When you want to disable the watchdog timer, your program should read I/O port 043 (hex).

If CPU processing comes to a standstill because of EMI or a software bug, your program's signals to I/O port address 443 to the timer will be interrupted. The timer will then automatically reset the CPU or invoke an IRQ, and data processing will continue normally.

The following program shows how you might program the watchdog timer in BASIC:

10 REM Watchdog timer example program 15 REM Watchdog timer interval set to 2 sec in BIOS 20 X=INP(&H443) REM Enable and refresh the watchdog 30 GOSUB 1000 REM Task #2, takes 2 sec to complete 40 X=INP(&H443) REM Refresh the watchdog 50 GOSUB 2000 REM Task #2, takes 2 sec to complete 60 X=INP(&H043) REM Disable the watchdog 70 END 1000 REM Subroutine #2, takes 2 seconds to complete

1070 RETURN 2000 REM Subroutine #2, takes 2 seconds to complete

2090 RETURN

Upgrading

This appendix gives instructions for

increasing the capabilities of your CPU

card. It covers:

 DRAM memory installation (SIMMs)

 CPU installation and upgrading

 Installing PC/104 modules

Appendix C Upgrading 57

Installing DRAM (SIMMs)

You can install anywhere from 1 MB to 32 MB of on-board

DRAM memory using 256 KBx36, 1 MBx36 or 4 MBx36 SIMMs

(Single In-line Memory Modules). Access time should be 80 ns or

less.

Memory installs in two 72-pin SIMM sockets. See the figure on

page 5 for help identifying the banks. You must fill both sockets,

and both SIMMs must be of the same capacity, i. e. you cannot

mix 256 KB SIMMs with 1 MB SIMMs. The following table

shows the memory size for different SIMM capacities:

System memory configuration SIMM size Pcs

1 MB 256 KB x 36 1 2 MB 256 KB x 36 2 4 MB 1 MB x 36 1 8 MB 1 MB x 36 2 16 MB 4 MB x 36 1 32 MB 4 MB x 36 2

The procedure for installing SIMMs appears below. Please follow

these steps carefully.

Warning! Completely disconnect power from the system

before you install SIMMs. Remove the CPU card from the chassis. .

Caution! Properly ground yourself (we recommend a

grounding wrist strap) before you touch the CPU card or SIMMs. Both are very susceptible to damage from static discharge. Place the card and SIMMs on a static-dissipative surface or into a static-shielding bag when they are not installed.

1. Locate the CPU cards memory banks, shown in the figure in

Chapter 1 (page 5).

58 PCA-6143P User's Manual

2. Install the SIMM cards. Install each SIMM so that its chips

faces the CPU and its gold pins point down into the SIMM

socket.

3. Slip each SIMM into a socket at a 45 degree angle and careful-

ly fit the bottom of the card against the connectors.

4. Gently push the SIMM into a perpendicular position until the

clips on the ends of the SIMM sockets snap into place.

5. Check to ensure that each SIMM is correctly seated and all

connector contacts touch. The SIMM should not move around

in its socket.

CPU installation and upgrading

This section tells how to install or upgrade the card's CPU. You

can upgrade your PCA-6143P to a higher powered 486 CPU at any

time. Simply remove the old 486 CPU, install the new and set the

jumpers for the CPU type and speed.

Warning! Disconnect all power from the chassis before you

remove or install the CPU card. Follow the power-down procedure outlined in the manual for your chassis. Unplug the power cord from the wall, don’t just turn off the power switch. If you are not sure what to do, take the job to an experienced professional.

Caution! The electronic components on this CPU card are

very sensitive to static electric charges. Use a grounding wrist strap to remove all static electricity before you touch any components. Place all components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis.

1. Disconnect power from the chassis and remove the CPU card.

Follow the instructions in the user's manual for your chassis.

You will also need to disconnect everything you connected in

Chapter 3, Connections.

Appendix C Upgrading 59

2. If you are upgrading the CPU, remove any existing CPU from

the socket. (See Chapter 1 for help locating the socket.) The

old chip may be difficult to remove. You may find spray chip

lubricant (designed for pin-grid-array devices, PGAs) and a

chip puller helpful (available at electronics hobbyist's supply

stores).

3. Plug in the new CPU into the empty socket. Follow the

instructions that came with the CPU or math coprocessor. If

you have no instructions, do the following: Lubricate the pins

of the CPU. Use lubricant designed for use with PGA devices.

This will make the new CPU slide in MUCH easier and reduce

the chance of bending pins or other damage. Next, carefully

align the CPU so it is parallel to the socket and the notch on the

corner of the CPU matches with the notch on the inside of the

socket. Carefully slide in the CPU. There will probably be a

gap between the CPU and the connector when it is fully seated

 do not push too hard!

4. Switch jumpers JP2, JP3 and JP31 to match the new CPU

according to the following table:

JP2 JP3 JP31

SX-25 Off 1-2 Closed SX-33 Off 1-2 Closed DX-25 2- 3 2-3 Closed DX-33 2- 3 2-3 Closed DX2-50 2- 3 2-3 Closed DX2-66 2- 3 2-3 Closed DX4-100 (3.45 V) 2-3 2-3 Open

5. Reinstall the CPU card according to the instructions in

Chapter 2.

signs of dirt, dust, wear and stress.

Warning! Always remove power from the complete system

before installing the CPU card. Follow all powerdown procedures outlined in the chassis user’s manual. To avoid injury to personnel, disconnect the power cord from the power source. Only qualified, experienced electronics personnel should access the interior of the chassis.

Caution! Never allow moisture or condensation to come in

contact with the PCA-6143P components or cables and connectors. Damage to sensitive components may occur.

Inspect all cables and connectors to verify that they are securely

fastened to their connecting components. Worn or stressed cables

or connectors should be replaced.

All peripheral equipment used with the PCA-6143P should be

properly maintained. Malfunctioning equipment should be

immediately replaced to prevent damage to the CPU.

PROBLEM

Will not boot up

SOLUTION

Make sure that all cards on the passive backplane are firmly seated

in their slots. Clean the pins on the cards and slot connectors on

the passive backplane if necessary.

Check the DC output of the power supply. All required voltages

(+5 V, + 12 V, etc.) should be present. The +5 V output should be

within the range 4.75 V to 5.25 V.

Make sure that the DRAM modules are correctly inserted into their

sockets and have the correct access time (usually 80 nsec or less)

Check that the CMOS is correctly set up. Check the HDD, FDD,

wait states, error hold, etc.

Make sure the add-on cards are OK. Remove or change add-on

cards and test again.

Ensure that the math co-processor is properly inserted in its socket.

Check the connections between the video card and monitor. Check

display adjustments, especially when using LCD displays. The

system may be booting up, but not displaying on the screen.

If you are booting from a floppy disk drive, make sure the floppy

is bootable. If booting from a hard drive, make sure that it is pro-

perly formatted for your DOS version. New disks must first be

partitioned (with FDISK) and formatted with FORMAT).

Check HDD and FDD cable connections. Make sure that the

floppy drive is designated drive A: (the end connector on the FDD

cable), and that the hard disk is designated drive C: (the end

connector on the HDD cable).

Check connections for the reset, keylock and power LED wires.

Remove completely or adjust the value of the terminating resistor

on your backplane.

Appendix E Maintenance and troubleshooting 77

Check for and remove viruses. The boot sector and partition table

on your HDD may be damaged.

PROBLEM

CMOS setup loss

SOLUTION

Make sure that your application software does not write to CMOS

data addresses.

PROBLEM

System hangs after working for a short time (about 20 minutes)

SOLUTION

Make sure the power switch is set to correct input range (110 or

220 VAC). If the correct range is set, check the quality of the input

power. It should be stable and between 90 and 120/200 and

240 VAC. PC equipment should not be connected to the end of a

power trunk line. Next, check the output of the power supply. The

+5 VDC supply should be between 4.75 and 5.25 VDC.

Make sure the temperature of the case is less than 60oC (140oF). If

necessary, clean the air filter and backplane.

Check that the SIMM DRAM modules have an access time of

80 nsec or less.

PROBLEM

Serial Port Failure

SOLUTION

Check cable connections between the PC and the remote terminal

equipment. Make sure that the remote terminal equipment is

functioning properly.

Check COM port assignment.

When using standard C, Pascal or BASIC serial port commands,

make sure that either the ports DTR/DSR and RTS/CTS lines are

looped back (shorted together in the connector), or the COM port

78 PCA-6143P User's Manual

is set to loop back mode. Test using diagnostic software such as

Checklt or QAPlus.

The RS-232 interface relies on good grounding for reliable

operation. Check that all equipment has a good connection to

ground, and that the ground potential is the same at both locations.

PROBLEM

Parallel Port Failure

SOLUTION

Make sure the printer cable is connected correctly.

Make sure that the printer is on-line and self-tests OK.

Make sure that application software is set correctly.

PROBLEM

FDD works incorrectly

SOLUTION

Check the connections between the CPU card and FDD.

Clean the magnetic head of the FDD. Make sure you are using

diskettes of the proper capacity and format.

Check that the FDD type is correctly set in CMOS.

Reset the BIOS to the default setting and try again.

Make sure the super I/O configuration is setup correctly.

PROBLEM

HDD works incorrectly

SOLUTION

Check cable connections. Check that the master/slave jumpers are

properly set. The boot drive should be the master.

Make sure the HDD type is correctly set in CMOS. Reset system

setup to BIOS default settings and try again.

Check for and remove viruses. The boot sector and partition table

on your HDD may be damaged.

Appendix E Maintenance and troubleshooting 79

Make sure the super I/O configuration is setup correctly.

Check for bad sectors on the hard disk (using a program such as

Norton Disk Doctor). This is a common problem with Conner

HDDs. If bad sectors are found, reformat the HDD.

PROBLEM

Add-on cards work incorrectly

SOLUTION

Check jumper and switch settings of add on cards.

Make sure that the card is firmly seated in its slot. Clean the pins

on the card and the passive backplane connector if necessary.

Make sure the bus speed setting in CMOS setup is 8 MHz. Check

that the shadow RAM and EMS settings in CMOS do not conflict

with the add-on cards firmware and I/O addresses.

Remove (or replace) the terminating resistors on the passive

backplane and test again. These resistors are especially important

for high speed add-on cards.

PROBLEM

Real-time clock is not accurate

SOLUTION

Under standard conditions the DS-12887 is accurate to within two

minutes per month.

Make sure the application software you are using does not

interrupts the RTC and/or writes improper data to the RTC.

PROBLEM

Software

SOLUTION

Make sure that the memory, system configuration, display and

HDD space meet the minimum requirements of the software.

Make sure the software is properly installed.

Check for and remove viruses.

APPENDIX

AMI BIOS error codes

This appendix lists the codes generated by

the AMI BIOS if it encounters a hardware

error during its POST (Power On Self

Test) routines.

Appendix F AMI BIOS error codes 81

Whenever you start up your system, the CPU card runs a series of

programs to test and initialize board hardware. If the routines

encounter an error in 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. Non-fatal

error messages usually appear on the screen along with the

following instructions:

Press <F1> to RESUME

Write down the message and press the F1 key to continue the

bootup sequence. The cure for most non-fatal error messages is

simply to run the BIOS SETUP program, discussed in Chapter 5.

If the routines encounter a fatal error, they will stop the tests and

output a message indicating which test failed. If the fatal error

comes before the screen device initializes, the card will indicate

the error code through a series of beeps.

You can also determine the number of the test that failed by

reading the LED indicators on the top of the PCA-6143P board.

Please make a note of any BIOS error codes before you contact

Advantech for technical support.

Beep codes

Beep codes indicate fatal errors through a series of audible tones

output through the card's buzzer or a speaker. The number of

beeps indicates the error, as shown in the following table:

BIOS error codes  Beep codes

Beeps Meaning

1 Refresh failure – The card's memory refresh circuitry is faulty. 2 Parity error – A parity error was detected in the base memory

(the first block of 64 KB) of the system.

3 Base 64 KB memory failure – A memory failure occurred within

the first 64 KB of system memory.

4 Timer not operational – Timer #1 on the card has generated an

error.

82 PCA-6143P User's Manual

Beeps Meaning

5 Processor error – The card's CPU has generated an error. 6 8042 Gate A20 failure – The keyboard controller (8042)

contains the Gate A20 switch which allows the CPU to operate in protected mode. This error message means that the BIOS is not able to switch the CPU into protected mode.

7 Processor exception interrupt error – The CPU has generated

an exception interrupt

8 Display memory read/write error – The system video adapter is

either missing or has faulty memory.

error.

9 ROM checksum error – The ROM checksum value does not

match the value encoded in the BIOS.

10 CMOS shutdown register read/write error – The shutdown

Note: This is not a fatal

Non-fatal error messages

Following are descriptions of the BIOS's non-fatal error messages:

8042 Gate A20 error

The gate-A20 portion of the keyboard controller (8042) has failed

to operate correctly. Replace the 8042 chip or the keyboard.

Address line short

An error has occurred in the address decoding circuitry of the card.

Cache memory bad, do not enable cache!

The BIOS has found the cache memory on the board to be

defective.

CH-2 timer error

Your card has two timer chips. An error with timer no. 1 is a fatal

error, explained above.

C: drive error

The BIOS is not receiving any response from hard disk C:. Check

the type of hard disk selected in the Standard CMOS Setup of the

BIOS Setup Program to see if the correct hard You may need to

run the Hard Disk Utility to correct this problem.

Appendix F AMI BIOS error codes 83

C: drive failure

The BIOS cannot get any response from hard disk drive C:. You

may need to replace the disk.

CMOS battery state low

The battery used to stored the CMOS values appears to be low.

CMOS checksum failure

After the CMOS values are saved, a checksum value is generated

to provide for error checking. If the previous value is different

from the value currently read, this message appears. To correct this

error, you should run the BIOS Setup Program.

CMOS display type mismatch

The type of video stored in CMOS does not match the type

detected by the BIOS. Run the BIOS Setup Program to correct this

error.

CMOS memory size mismatch

If the BIOS finds the amount of memory on your motherboard to

be different from the amount indicated in the CMOS it generates

this message. Run the BIOS Setup Program to correct this error.

CMOS system options not set

The values stored in CMOS are either corrupt or nonexistent. Run

the BIOS Setup Program to correct this error.

CMOS time and date not set

Run Standard CMOS Setup in the BIOS setup program to set the

date and time in the CMOS.

D: drive error

boot-up the system with it. Use another boot diskette and follow

the instructions on the screen.

KB/Interface error

The BIOS has found an error with the board's keyboard connector

Keyboard error

The BIOS has encountered a timing problem with the keyboard.

Make sure you have an AMI Keyboard BIOS installed in your

system. You may also have set the "Keyboard" option in the

Standard CMOS Setup to "Not Installed", which will cause the

BIOS to skip the keyboard POST routines.

Appendix F AMI BIOS error codes 85

Keyboard is locked... Unlock it.

The keyboard lock on the system is engaged. The system must be

unlocked to continue the boot-up procedure.

No ROM BASIC

This error occurs when a proper bootable sector cannot be found

on either the floppy diskette drive A: or the hard disk drive C:. The

BIOS will try at this point to run ROM BASIC, and this error

message will be generated when the BIOS does not find it.

Off board parity error

The BIOS has encountered a parity error in some memory in-

stalled in an I/O expansion slot. The message will appear as

follows:

OFF BOARD PARITY ERROR ADDR (HEX) = (XXXX)

XXXX is the address (in hexadecimal) at which the error occurred.

On board parity error

The BIOS has encountered a parity error in some memory in-

stalled in the CPU card. The message will appear as follows:

ON BOARD PARITY ERROR ADDR (HEX) = (XXXX)
