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 Board layout Safety precautions Jumper settings Installing DRAM (SIMMs) Chapter 1 Hardware Configuration 1 CHAPTER Introduction The PCA-6149 is an all-in-one single board 486 computer that includes an on-board SVGA controller with PCI bus and ISA bus support. It packs all the functions of an industrial computer, including display capabilities, on a single full-size card. The PCA-6149 is fully PC/AT compatible, so your software will run without modifications. The on-board PCI bus SVGA controller uses the ET4000/W32P chipset with 1 or 2 MB video memory. This chipset, used with the local PCI bus, enables 32-bit graphic throughput at up to 33 MHz. The ET4000/W32 also offers Windows graphics acceleration. These features are excellent for display-intensive applications. Another feature of the PCA-6149 is the inclusion of a fast VL bus enhanced IDE controller. This controller supports mode 3, which enables data transfer rates in excess of 11 MB/second. Up to four IDE devices can be connected, including large hard disks (up to 8 GB), CD-ROM drives, Tape backup drives or other enhanced IDE devices. On-board features also include two high-speed RS-232 serial ports with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive controller. In addition to the 486's 8 KB of on-chip cache memory, the PCA-6149 includes an extra 256 KB or 512 KB of second level cache memory on-board. If program execution is halted by a program bug or EMI, the board's 12- level watchdog timer can automatically reset the CPU or generate an interrupt. This ensures reliability in unmanned or standalone systems. The timer interval of the watchdog timer is set in the BIOS, eliminating jumper switch setting. The PCA-6149 provides four 72-pin SIMM (Single In-line Memory Module) sockets for its on-board system DRAM. These sockets give you the flexibility to configure your system from 1 MB to 256 MB of DRAM using the most economical combination of SIMMs. The CMOS data of the PCA-6149 is backed up in EEPROM, which avoids data loss, even when the battery fails. To make using the DX4-100 easy, the PCA-6149 includes an on-board DC-to-DC converter that automatically switches to 3.3 V. 2 PCA-6149 User's Manual Specifications System CPU: 80486SX/DX/DX2/DX4-25/33/40/50/66/75/100 MHz, or P24T Pentium Overdrive Processor Cache memory size: 8 KB on-chip and 256/512 KB 2nd level Bus interface: ISA and PCI (PC/AT) bus Chipset: SIS 496/497 BIOS: AWARD Display controller: SVGA, PCI bus, ET4000/W32P chipset with 1 MB standard video memory, upgradable to 2 MB.

To avoid electric shock, always disconnect the power from your PC chassis before you work on it. Don’t touch any components on 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 antistatic packaging when it is not installed in the PC, and place it on a static dissipative mat when you are working with it. Wear a grounding wrist strap for continuous protection. Chapter 1 Hardware Configuration 7 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 3) to configure the serial port addresses, floppy/hard disk drive types and system operat- ing parameters. Connections, such as hard disk cables, appear in Chapter 2. For the locations of each jumper, see the board layout diagram depicted earlier in this chapter. 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 connect either pins 1 and 2 or 2 and 3. 3 2 1 Open Open Open Open Open Closed Closed Closed Closed Closed Closed 2-3 Closed 2-3 Closed 2-3 Closed 2-3 Closed 2-3 You 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. 8 PCA-6149 User's Manual CPU type select (JP1, 2, 5, 6, 12~20, 22~25, 27) In order for the system to function properly, the jumpers must be set to accommodate the CPU installed on the CPU card.

See the board layout diagram depicted earlier in this chapter. You can use anywhere from 1 MB to 256 MB of DRAM with your PCA-6149. The card provides four 72-pin SIMM (Single In-Line Memory Module) sockets that each accept from 1 to 64 MB DRAM. The sockets (numbered from 1 to 4) are arranged into four banks. The following table shows the bank assignments for the SIMM sockets: Bank SIMM socket(s) Size 1 SIMM1 72-pin 2 SIMM2 72-pin 3 SIMM3 72-pin 4 SIMM4 72-pin The PCA-6149's memory sockets accept any combination of SIMMs (up to 256 MB), inserted in any order. 14 PCA-6149 User's Manual 2 Connecting Peripherals This chapter tells how to connect periph- erals, switches and indicators to the PCA-6149 board. You can access most of the connectors from 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. Chapter 2 Connecting peripherals 15 CHAPTER The following table lists the connectors on the PCA-6149. See Chapter 1 for help locating the connectors. Connectors Label Component CN1 1st EIDE connector CN2 2nd EIDE connector CN3 FDD connector CN4 Parallel port connector CN5 VGA feature connector J1 CPU cooling fan power connector J7 External keyboard connector J8 VGA connector J9 Keyboard or PS/2 mouse connector JP7 Power LED and keylock JP8 External speaker JP9 Turbo LED JP10 Reset switch JP11 Turbo switch JP30 HDD LED The following sections tell how to make each connection. In most cases, you will simply need to connect a standard cable. 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. 16 PCA-6149 User's Manual Enhanced IDE connectors (CN1, CN2) You can attach four IDE (Integrated Device Electronics) drives to the PCA-6149's internal controller. The PCA-6149 CPU card has two EIDE connectors: CN1 and CN2. Each EIDE connector can support two IDE devices. CN1 is the first EIDE connector, and must be used first. CN2 is the second EIDE connector. There must be at least one device attached to CN1 before CN2 can be used. Wire number 1 on the cable is red or blue, the other wires are gray. Connect one end to connector CN1 or CN2 on the CPU card. Make sure that the red (or blue) wire corresponds to pin 1 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 by setting the 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 1 on the cable should also connect to pin 1 on the hard drive connector, which is labeled on the drive circuit board. Check the documentation that came with the drive for more information. Connect the second drive as described above on CN1 or CN2. Chapter 2 Connecting peripherals 17 Floppy drive connector (CN3) You can attach up to two floppy disk drives to the PCA-6149'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. Parallel port (CN4) The parallel port is normally used to connect the CPU card to a printer. The PCA-6149 includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN4. The 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 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 CN4 on the CPU card. Wire 1 of the cable is red or blue, and the other wires are gray. Make sure that wire 1 corresponds to pin 1 of CN4. Pin 1 is on the right side of CN4. 18 PCA-6149 User's Manual Keyboard and PS/2 mouse connectors (J7, J9) The PCA-6149 board provides two keyboard connectors. A 5-pin connector (J7) supports passive backplane applications. A second 6- pin mini-DIN connector (J9) 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 connec- tor.

Chapter 2 Connecting peripherals 19 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. Power LED and keylock (JP7) You can connect an LED to indicate when the CPU card is on. Pin 1 of JP7 supplies power to the LED and Pin 3 is the ground. 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 JP7. The pin assignments for JP7 appear in the following table: Power LED and keylock (JP7) Pin Function 1 LED Power (+5 V) 2 No Connector 3 Ground 4 Keyboard lock 5 Ground External speaker (JP8) The CPU card has its own buzzer. You can also connect to the external speaker on your computer chassis. Connect leads to connector JP8 as shown below: External speaker (JP8) Pin Function 1 +5 V 2 Speaker 3 Speaker 4 Speaker 20 PCA-6149 User's Manual Turbo LED (JP9) You can connect a LED indicator across jumper JP9 to indicate when the CPU is in Turbo mode. Marks on the circuit board indicate LED polarity. Reset switch (JP10) 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 JP10. Turbo switch (JP11) You can connect a switch across the pins of jumper JP11 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 JP11 is open. When jumper JP11 is closed, the CPU is fixed in Turbo mode. To switch into Turbo mode from the keyboard simultaneously press the , and keypad plus (+) keys. To switch into non-Turbo mode press the , and keypad minus (-) keys. Hard disk drive LED (JP30) You can connect a LED to connector JP30 to indicate when the HDD is active. Marks on the circuit board indicate LED polarity. Chapter 2 Connecting peripherals 21 Display connectors VGA connector (J8) The PCA-6149 provides a VGA controller for high resolution VGA interface. J8 is a DB-15 connector for VGA monitor input. Feature connector (CN5) The PCA-6149's VGA controller offers a feature connector, which can connect to another multimedia display card for special display func- tions. The following chart lists the feature connector's pin assign- ments: Feature connector (CN5) Pin Function Pin Function 1 PBX/C0 14 Ground 2 PGX/C1 15 Ground 3 PRX/C2 16 Ground 4 PIX/C3 17 ESYC 5 SBX/C4 18 ECLK 6 SGX/C5 19 EVID 7 SRX/C6 20 Not used 8 SIX/C7 21 Ground 9 OPCLK 22 Ground 10 BLANK 23 Ground 11 HSNC 24 Ground 12 VSNC 25 Not used 13 Ground 26 Not used 22 PCA-6149 User's Manual Cooling fan power connector (J1) The PCA-6149 provides a +5 V/+12 V 4-pin power connector for CPU cooling fan. CPU power connector (J1) Pin Function 1 +5 V 2 GND 3 GND 4 +12 V Serial ports The PCA-6149 offers two RS-232 serial ports. 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, using the BIOS Advanced Setup program, covered in Chapter 3. The card mounting bracket holds the serial port connector for the one port, and the parallel port and serial port adapter kit (supplied with the card) holds the connector for the other port. This lets you connect and disconnect cables after you install the card. The DB-9 connector on the bottom of the bracket is the first RS-232 port, COM1. The DB-9 connector on the adapter kit is the second serial port, COM2. Chapter 2 Connecting peripherals 23 RS-232 connections (COM1, COM2) 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.

Quick Power On Self Test This option speeds up the Power-On Self Test (POST) conducted as soon as the computer is turned on. When enabled, BIOS shortens or skips some of the items during the test. When disabled, normal POST procedures assumes. Boot Sequence This function determines the sequence in which the computer will search the drives for the disk operating system (i.e. DOS). The default value is "A, C". C,A System will first search the hard drive, then the floppy drive. A,C System will first search the floppy drive, then the hard drive. Boot Up Floppy Seek During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360 KB type is 40 tracks while 720 KB, 1.2 MB, and 1.44 MB are all 80 tracks. Enabled BIOS searches the floppy drive to determine if it is 40 or 80 tracks. Note that BIOS cannot differentiate 720 KB, 1.2 MB, and 1.44 MB type drives as they are all 80 tracks. Disabled BIOS will not search for the floppy drive type by track number. Note that there will not be any warning message if the drive installed is 360 KB. Boot Up NumLock Status The default is "On". On Keypad boots up to number keys. Off Keypad boots up to arrow keys. Chapter 3 Award BIOS setup 29 Boot Up System Speed Sets the speed of the system immediately after power-up to high or low. Gate A20 option Normal Keyboard Fast Chipset Typematic Rate setting The typematic rate determines the characters per second accepted by the computer.

PCI device# IDSEL # 131 230 329 428 36 PCA-6149 User's Manual Slot 1 Using INT# , Slot 2 Using INT#, Slot 3 Using INT#, Slot 4 Using INT# These allow you to assign each PCI device to INT# A, B, C, or D. Generally, choose AUTO unless you have a device that does not tell BIOS which INT# to use. Note: For multifunction PCI devices, choose only AUTO. 1st/2nd/3rd/4th Available IRQ The system BIOS will assign the specified available IRQ to the found PCI devices. PCI IRQ Activated by This tells the chipset whether the IRQ signals input is level or edge trigger. PCI IDE 2nd Channel This option enables or disables the second channel of the PCI/IDE card. It includes I/O port (170H~177H) and IRQ15 assignment. PCI IDE IRQ Map to For the specified slot, the BIOS will determine the location of the PCI IDE device and assign IRQ14 for the primary IDE INT#, and IRQ15 for the secondary IDE INT#. If ISA is chosen, BIOS will not assign any IRQ even if a PCI IDE is found. Primary IDE NT#, Secondary IDE INT# These determine which INT# the PCI IDE card is using for its inter- rupts.

This chapter describes the installation and use of the display utilities and drivers. Chapter 4 PCI VGA Setup 39 CHAPTER Before you begin To facilitate the installation of the enhanced display device drivers and utility software, you should read the instructions in this chapter carefully before you attempt installation. The enhanced display drivers for the VIEWTOP ET-Series board are located on the software installa- tion diskette. You must install the drivers and utility software by using the supplied SETUP program for DOS driver. (WINSETUP program for Windows 3.1x Driver.) Note: The files on the software installation diskette are compressed. Do not attempt to install drivers by copying the files manually. You must use the supplied SETUP (or WINSETUP) program to install the drivers (except in the case of Windows NT, which can read the compressed files on the software installation diskette directly). Before you begin, it is important to note that most display drivers need to have the relevant software application already installed in the system prior to installing the enhanced display drivers. In addition, many of the installation procedures assume that you are familiar with both the relevant software application and certain operating system commands. Please review the relevant operating system commands and the pertinent sections of your application software's user manual before performing the installation. 40 PCA-6149 User's Manual Installation To install the enhanced display drivers and utilities, follow these steps: 1. If you have not already done so, make a backup copy of the software installation diskette and store the original in a safe place. Refer to your operating system manual for details on how to duplicate a diskette. You should use the backup copy you have made for all subsequent steps. Alternatively, you can copy all the files on the software installation diskette to your hard disk and install the drivers from there. The steps below assume you are installing from a diskette. 2. Insert the backup copy of the software installation diskette into drive A: or B:. From the DOS command line, run the SETUP program by typing: A: SETUP Enter (or B: SETUP Enter as appropriate). 3. Scroll through the list of options by using a mouse or the cursor keys until you come to the option you wish to install. Click on the left mouse button or press to select the option. 4. After reading the application notes (if any), click the left mouse button or press to continue with the installation proce- dure. The SETUP program will search your environment path in attempt to locate the installed application, and you will be prompt- ed to confirm a directory to which the files should be copied (normally the application's directory). You also have the option of entering a drive and directory of your choice. If the directory you choose does not exist, it will be created for you. The relevant files will be copied there or to appropriate sub-directories. 5. Finally, if an application specific setup program or procedure is required in order to configure the software to recognize the new driver(s) and the SETUP program has been able to locate the application specific program, you will be given the option of running the relevant program to configure the application at this time. Chapter 4 PCI VGA Setup 41 6. After the installation procedure is completed, you will be returned to SETUP program. Select another option for installation as required. To exit SETUP, click on the right mouse button or press . You will be prompted for confirmation before returning to the DOS command prompt. 42 PCA-6149 User's Manual A Programming the Watchdog Timer The PCA-6149 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 A Programming the Watchdog Timer 43 APPENDIX 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 IRQ11. 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 44 PCA-6149 User's Manual B POST LEDs This appendix lists the codes generated by the POST (Power On Self Test) routines. It also discusses how to read the PCA-6149's POST LED indicators. Appendix B POST LEDs 45 APPENDIX Whenever you start up your system, the CPU card runs a series of programs to test and initialize board hardware. If the routines encoun- ter 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 to RESUME Write down the message and press the F1 key to continue the bootup sequence. The cure for most nonfatal error messages is simply to run the BIOS SETUP program, discussed in Chapter 3. 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-6157 board. Please make a note of any BIOS error codes before you contact Advantech for technical support. 46 PCA-6149 User's Manual POST LEDs Before the BIOS performs each system test, it writes a checkpoint code to I/O address 80H. If the test fails, the code will stay in memory. You can read the code and determine which test has failed. The PCA-6149’s POST LED indicators make this process extremely easy. You don’t need any special diagnostic tools, you just read the POST code from the LEDs. The table below shows how to read the LEDs, a series of eight LEDs located in the top left-hand corner of the board. SELF-TEST INDICATORS !!! ! ! ! ! !
