Locating components J1 This section identifies the location of the card's major components. It also includes a list of the function of each of the card jumpers. The following figure gives an overall view of the card.
Jumpers and connectors Connectors on the board link it to external devices such as hard disk drives, a keyboard or PC/104 modules. In addition, the board has a number of jumpers which you use to configure it for your application. The table below lists the function of each of the board jumpers and connectors. Later sections in this chapter give instructions on setting jumpers and detailed information on each jumper setting. Chapter 3 gives instructions for connecting external devices to your card.

If you ordered DRAM SIMMs along with your card, the SIMMs may already be installed.
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.
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.

CHAPTER Installation 2 This chapter gives guidelines 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.
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.
CHAPTER Connecting peripherals 3 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.
The following table lists the connectors on the PCA-6143P. See Chapter 1 (page 5) for help with locating the connectors.
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.
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.
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.
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.
Turbo LED (JP13) You can connect a LED indicator across jumper JP13 to indicate when the CPU is in Turbo mode. Marks on the circuit board indicate LED polarity (the lower pin is positive). External speaker (JP10) The CPU card has its own buzzer. You can also connect to the external speaker on your computer chassis. Connect leads to connector JP10 as shown below: External speaker (JP10) Pin no.
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.
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.
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.

CHAPTER Power-up 4 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.
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.
CHAPTER BIOS diagnostics and SETUP 5 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.
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.
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.
copy down the line, you can then press to continue the boot procedure. After the POST routines are complete, the following message appears: Hit if you want to run SETUP Press the key to access the BIOS setup program. The BIOS Setup screen will then appear.
Standard CMOS Setup Standard CMOS setup configures options that most users will need to change. Highlight Standard CMOS Setup in the main screen and press . A warning message appears (shown below) whenever you select either Standard CMOS Setup or Advanced CMOS Setup from the main screen. Simply press any key to continue or ESC to abort.

APPENDIX Flash/ROM disk A 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.
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.
å I/O address selection (SW1) Positions 1 and 2 on DIP switch SW1 control the disk's I/O address. Position 1 Off Off On On Position 2 Off On Off On I/O address (HEX) Disabled 200-201 240-241 280-281 å 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.
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.
Example 2 You (try to) install the Flash/ROM disk as drive C: Before installing Flash/ROM disk DOS 5.0+ A FDD B FDD C HDD After installing Flash/ROM disk DOS 5.0+ A FDD B FDD C HDD D Flash/ROM 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).
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.

CHAPTER B 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.
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.
APPENDIX C Upgrading This appendix gives instructions for increasing the capabilities of your CPU card.
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.
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 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.
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.
Installing PC/104 modules The PCA-6143P's PC/104 connectors let you attach PC/104 expansion modules. These modules perform the functions of traditional plug-in expansion cards, but save space and valuable slots.

APPENDIX E Maintenance and troubleshooting This appendix describes the general maintenance that your CPU card requires to ensure reliable operation. It then gives some solutions to common card troubleshooting problems.
General maintenance As with any electronic equipment, an adequate maintenance program will ensure reliable performance. In general terms, maintenance includes periodic inspection of the card and peripherals to ensure that they are clean and free from 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.
Industrial PC system troubleshooting guide 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.
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.
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.
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.
APPENDIX F 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.
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.
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.
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.
Diskette boot failure The diskette used to boot-up in floppy drive A: is corrupt, which means you cannot use it to boot-up the system. Use another boot diskette and follow the instructions on the screen. Display switch not proper Jumper JP15 is set incorrectly. (Remember to shut down the system first). DMA #1 error An error has occurred with the board's first DMA channel. DMA #2 error An error has occurred with the board's second DMA channel.
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.
