Chapter 1 Hardware Configuration 1

Introduction

The half-size PCA-6134P comes equipped with an 80386SX-40 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 (which controls up to 2 IDE hard drives), 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-6134P to be used in stand-alone systems or unattended environments. The PCA-6134P’s industrial-grade construction ensures continuous, reliable operation in harsh industrial environments at temperatures up to 140oF (60oC).

W e designed the PCA-6134P 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. See Appendix A for details.

Built using CMOS technology, the PCA-6134P 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 on-board memory of 1 to 16 MB.

Chapter 1 Hardware Configuration 7

Safety precautions

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

1 . T o 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. W ear 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 • Parity checking enabled

• Parallel port IRQ7, DRQ1, DACK1 • Color display attached

8 PCA-6134P 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. T o “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.

Y ou may find pair of needle-nose pliers useful for setting the jumpers. 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 (JP16)

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 JP16 to color . The next table shows the available jumper settings:

Display type selection

JP16 Setting

Open Monochrome Closed Color (default)

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 JP8 as shown in the following table:

Watchdog timer setup

JP8 Setting

1-2 System reset (default) 2-3 IRQ15

Chapter 1 Hardware Configuration 9

Parallel port IRQ, DACK and DRQ selection (JP19, JP20, JP21)

Y ou can set the IRQ (JP19), DACK (JP20) and DRQ (JP21) of the parallel port. The following tables show the available options :

Parallel port IRQ selection

JP19 IRQ no

1-2 IRQ7 (default) 2-3 IRQ5

Parallel port DACK selection

JP20 DACK no

1-2 DACK1 (default) 2-3 DACK3

Parallel port DRQ selection

JP21 DRQ no

1-2 DRQ1 (default) 2-3 DRQ3

Parity check (JP23)

You can set the parity checking to enabled/disabled. If you use memory without a parity bit, you must disable parity checking.

The next table shows the options:

CHAPTER

Installation

This chapter gives a general procedure for installing your CPU card into an PC chassis with an AT-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, tak e the job to an e xperienced 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. Fasten the card I/O bracket to the case with the screw.

After you have installed the CPU card, you will need to attach the connecting cables as described in the following chapter. When you are finished installing the CPU card, 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 on page 10.

CHAPTER

Connecting Peripherals

This chapter tells how to connect peripherals, switches and indicators to the PCA-6134P board. Y ou 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-6134P. See Chapter 1 for help locating the connectors.

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 e xperienced 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-6134P User's Manual

Floppy drive connections

You can attach up to two floppy disk drives to the PCA-6134P's onboard 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. W ire 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 you desire, 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

Y ou can attach two IDE (Integrated Device Electronics) hard disk drives to the PCA-6134P internal controller. The card comes with a 40-pin flat-cable piggyback cable. This cable has three identical 40pin 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. 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.

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-6134P 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 and a

16 PCA-6134P User's Manual

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.

T o 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, see the figure on page 5.

The pin assignments for the connector appear in Appendix D.

Keyboard connectors

The PCA-6134P 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 (JP4)

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 JP4.

Chapter 3 Connecting Peripherals 17

Power LED and keylock (JP5)

Y ou can connect an LED to indicate when the CPU card is on. Pin 1 of JP5 supplies power to the LED and Pin 3 is the ground. For help finding JP5 see the figure on 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 JP5. The pin assignments for JP5 appear in the following table:

Power LED and keylock (JP5)

Pin Function

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

Hard disk drive LED (JP3)

Y ou can connect a LED to connector JP3 to indicate when the HDD is active. Marks on the circuit board indicate LED polarity (the pin on the left is positive).

Turbo switch (JP1)

You can connect a switch across the pins of jumper JP1 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 JP1 is open. When jumper JP1 is closed, the CPU is fixed in Turbo mode. T o switch into T urbo mode from the keyboard simultaneously press the Ctrl, Alt and keypad plus (+) keys. T o switch into nonTurbo mode press the Ctrl, Alt and keypad minus (-) keys.

Serial ports

The PCA-6134P 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.

Y ou can select the address for each port (3F8H [COM1], 2F8H [COM2] or 3E8H) or disable it, using 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 and RS-485 are popular for industrial and laboratory communication because they offer high noise resistance and long range (up to 4000 ft, 1200 m). 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 JP14, 15, 17, 18, 22, 24 and JP25 according to the following table:

!RS-422 signal wiring

RS-422 is used for long-distance point-to-point connections. RS-422 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:

!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.

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 T est) 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, AL T 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.

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 Test) 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-6134P 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-6134P’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 it. 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 copy

Chapter 5 BIOS Diagnostics and Setup 29

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 following screen will then appear.

BIOS Setup Main Menu

Y ou use the following keys to control the BIOS SETUP program:

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

Flash/ROM Disk

APPENDIX

Appendix A Flash/ROM Disk 45

The PCA-6134P 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/ROM disk supports the following memory devices, or their equivalents:

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.

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. The following table shows the memory chips you will need to emulate 360 KB, 720 KB, 1.2 MB and 1.44 MB floppy drives.

Y ou will need to set jumpers JP9 ~ JP1 1 to match the type (Flash, SRAM 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 JP9 ~ JP11.

Drive configuration

Before you activate the Flash/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/ROM drive. DIP switch SW1 controls each of these settings, as described in the following sections:

Appendix A Flash/ROM Disk 47

! I/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 Disable 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 Memory address (HEX)

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

! Drive emulated (SW1)

Positions 5 and 6 of SW1 control the DOS drive emulated by the Flash/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/ROM disk depends on the floppy or hard disks installed in the system. If you are using a DOS version prior to DOS 5.0, the drive designation may also differ .

48 PCA-6134P User's Manual

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/ROM disk

If you wish to have the system boot from the Flash/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-6134P, 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!.

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.

50 PCA-6134P User's Manual

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/ROM disk (set by positions 3 and 4 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.

Programming the Watchdog Timer

The PCA-6134P 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 53

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:

1 0 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 com-

plete

1070 RETURN 2000 REM Subroutine #2, takes 2 seconds to com-

plete

Upgrading

This appendix gives instructions for increasing the capabilities of your CPU card. It covers:

• DRAM memory isnstallation (SIMMs)

• Installing PC/104 modules

Appendix C Upgrading 55

Installing DRAM (SIMMs)

Y ou can install anywhere from 1 MB to 16 MB of on-board DRAM memory using 256 KBx36, 1 MBx36 or 4 MBx36 SIMMs (Single Inline Memory Modules). Access time should be 80 ns or less.

Memory installs in one bank composed of two SIMM sockets. See the figure on page 5 for help identifying the banks. The following table shows the memory size for different SIMM capacities:

System memory size 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

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 on

page 5.

2. Install the SIMM cards. Install each SIMM so that its chips face away from the CPU and its gold pins point down into the SIMM socket.

56 PCA-6134P User's Manual

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

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.

6 . If you use SIMMs that do not make provision for a parity bit,

jumper JP23 should be closed.

7 . If your system operates at 40 MHz or more, it is advisable to

obtain 70ns (or faster) memory. At lower speeds 80 ns memory should be sufficient.

Installing PC/104 modules

The PCA-6134P's PC/104 connector let you attach PC/104 modules. These modules perform the functions of traditional plug-in expansion cards, but save space and valuable slots. Advantech modules include:

• PCM-3510 Super VGA module

• PCM-3520 Flat panel/CRT VGA module

• PCM-3110 PCMCIA module

• PCM-3660 Ethernet module

• PCM-3718 30 KHz A/D module

• PCM-3724 48-channel DIO module

PC/104 modules are produced by over a dozen manufacturers, and the PC/104 form factor is being advanced as an appendix to the ISA bus standard.

If you want to make your own PC/104 module, the figure on the following page shows module dimensions. A PC/104 breadboard module (PCM-3910) is also available. Pin assignments for the connector appear in Appendix D. For further information, contact your Advantech distributor or sales representative.
