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-6151 is a cost-effective, all-in-one single board Pentium CPU card which can release Pentium’s full potential and provide unprecedented performance compared to current 64-bit processor board. The PCA-6151 offers all the functions of an industrial computer on a single board, half-size CPU card. This card uses a Pentium, AMD K5 CPU or Cyrix M1 and can have up to 64 MB nd DRAM. It also supports PB-SRAM 2 level cache size from 256KB to 512KB through an on board COAST module. The PCA-6151 utilizes a two-chip solution, allowing on board DRAM to be shared with the built-in VGA controller. In this configuration the chipset always acts as the arbiter between memory bus masters. This system insures efficient memory allocation while substantially reducing the overall system cost. On-board features include one RS-232 port, one RS-232/422/485 port, one multi-mode parallel (ECP/EPP/SPP) port, a floppy drive control- ler and a keyboard & PS/2 mouse interface. The built-in high speed PCI IDE controller supports both PIO and bus master modes. Up to two IDE devices can be connected, including large hard disks, CD-ROM drives, tape backup drives and other IDE devices. The PCA-6151 also features power management to minimize power consumption. It complies with the ”Green Function” standard and supports three types of power saving features: Doze mode, Standby mode and Suspend mode. A watchdog timer can automatically reset the system or generate an interrupt should the system stop due to a program bug or EMI. 2 PCA-6151 User's Manual Specifications System • CPU: Intel Pentium 75/90/100/120/133/150/166/200 MHz AMD K5, Cyrix M1 • BIOS: AWARD 128 KB memory; supports plug and play • Chipset: SiS 5596/5513 • L2 cache: Direct map write-back or write-through cache module - 256 KB/512 KB Synchronous (Pipeline Burst) SRAM • Green function: Features power management option via BIOS, activated by keyboard or mouse activity.

Keyboard connector CN11 Main Power Input CN12 VGA connector CN13 COM1 connector CN14 Keyboard & P/S2 Mouse connector Chapter 1 Hardware Configuration 5 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 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. 6 PCA-6151 User's Manual 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 operating 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 Closed Closed Closed Closed 2-3 Closed 2-3 Closed 2-3 Open Open Closed Closed 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. Chapter 1 Hardware Configuration 7 CPU type select (J3, J4, J6, J7, J8) 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 64 MB of DRAM with your PCA-6151. The card provides two 72-pin SIMM sockets that accept from 1 to 32 MB each. The sockets (numbered from 1 to 2) are arranged into two banks. Chapter 1 Hardware Configuration 11 12 PCA-6151 User's Manual 2 Connecting Peripherals This chapter tells how to connect peripherals, switches and indicators to the PCA-6151 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 13 CHAPTER The following table lists the connectors on the PCA-6151. Connectors Number Function CN1 KB Lock CN2 PC/104 Con. A CN3 PC/104 Con.

Keyboard Connector CN11 Main Power Input CN12 VGA Connector CN13 COM1 Connector CN14 Keyboard and PS/2 Mouse Connector 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. 14 PCA-6151 User's Manual Enhanced IDE connectors (CN4) You can attach two IDE (Integrated Device Electronics) drives to the PCA-6151’s internal controller. The PCA-6151 CPU card has an EIDE connector, CN4. Wire number 1 on the cable is red or blue, the other wires are gray. Connect one end to connector CN4 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 CN4. VGA display connector (CN12) The PCA-6151 provides a VGA controller for high resolution VGA interface. CN12 is a DB-15 connector for VGA monitor input. Chapter 2 Connecting Peripherals 15 Floppy drive connector (CN8) You can attach up to two floppy disk drives to the PCA-6151’s on-board controller. You can use any combination of 5.25" (360 KB/1.2 MB) and/or 3.5" (720 KB/1.44/2.88 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 connector (CN5) The parallel port is normally used to connect the CPU card to a printer. The PCA-6151 includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN5. 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 CN5 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 CN5. Pin 1 is on the right side of CN5. 16 PCA-6151 User's Manual Keyboard & PS/2 mouse connectors (CN14) The PCA-6151 board provides a keyboard connector. A 6-pin mini-DIN connector (CN14) 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 and to a PS/2 mouse connector. Reset switch (J14) 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 J14. Hard disk drive LED (CN6) You can connect a LED to connector CN6 to indicate when the HDD is active. Marks on the circuit board indicate LED polarity. Serial Ports The PCA-6151 offers two serial ports: COM1 in RS-232, COM2 in 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 ( For example,3F8H [COM1], 2F8H [COM2]) 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 17 Serial port connections (COM1, COM2) Connector Function COM1 RS-232 COM2 RS-232/422/485 RS-232 connection (COM1) Different devices implement the RS-232 standard in different ways.

You must first select the Security Option in the BIOS FEATURES SETUP to be either “Setup” or “System.” IDE HDD auto detection “IDE HDD AUTO DETECTION” automatically self-detect for the correct hard disk type. Save & Exit setup If you select this and press the [Enter] key, the values entered in the setup utilities will be recorded in the CMOS memory of the chipset. The microprocessor will check this every time you turn your system on and compare this to what it finds as it checks the system. This record is required for the system to operate. Exit without saving Selecting this option and pressing the [Enter] key lets you exit the Setup program without recording any new values or changing old ones. 32 PCA-6155 User's Manual A Programming the Watchdog Timer The PCA-6151 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 standalone and unmanned environments. Appendix A Programming the Watchdog Timer 33 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). The output data is a value timer. You can write from 01 (hex) to 3E (hex), and the related timer is 1 sec. to 63 sec. After data entry, your program must refresh the watchdog timer by rewriting the I/O port 443 (hex) while simultaneously setting it. When you want to disable the watchdog timer, your program should read I/O port 043 (hex). The following is an example of a program for the watchdog timer: Step 1 Out 443h data REM Start and reset the watchdog timer Step 2 Your application task #1 Step 3 Out 443h, data REM Reset the timer Step 4 Your application task #2 Step 5 Out 443h, data REM Reset the timer Step 6 in 043h, REM Disable the watchdog timer Data Values 01 1 sec. 02 2 sec. 03 3 sec. 04 4 sec. . . . 3E 63 sec. 34 PCA-6151 User's Manual B Upgrading This appendix gives instructions for increasing the capabilities of your CPU card.
