Sections include: • Introduction • Features • Specifications • Board layout and dimensions 1.1 Introduction The PCA-6770 all-in-one industrial grade PCI-bus CPU card uses Intel’s highly acclaimed Celeron® processor or Pentium® III processor, together with the Intel 440BX PCI chipset. The CPU provides 256 KB for Pentium III or 128 KB on-CPU L2 cache for Celeron, eliminating the need for external SRAM chips. It has one PCI EIDE interface for up to two devices and a floppy disk drive interface for up to two devices. Other features include two RS-232 serial ports (16C550 UARTs with 16-byte FIFO or compatible), one enhanced parallel port (supports SPP/EPP/ECP) and one USB (Universal Serial Bus) port. The PCI enhanced IDE controller supports Ultra DMA/33 and PIO Mode 4 operation. This provides data transfer rates of over 33 MB/sec. System Bios supports boot-up from an IDE CD-ROM, SCSI CD-ROM and LS120. A backup of CMOS data is stored in the Flash memory, which protects data even after a battery failure. Also included is a 62level Watchdog timer which resets the CPU or generates an interrupt if a program cannot be executed normally. This enables reliable operation in unattended environments. The PCA-6770 offers several impressive industrial features such as VGA AGP controller, two SODIMM slots for a total of 256 MB RAM memory and a 10/100Base-T networking controller. In addition, the PCA-6770 series supports a solid state disk (SSD) using a CompactFlash™ disk that is not as vulnerable to the hazards of an industrial computing environment. These features make it an ideal choice for applications that require both high performance and full functionality. 2 PCA-6770 User's Manual 1.2 Specifications CPU: Socket 370 for Intel® Pentium III processors up to 650 MHz or higher in the future (Rev.

It includes instructions on setting jumpers, and connecting peripherals, switches and indicators. Be sure to read all the safety precautions before you begin the installation procedure. 2.1 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. 2.2 Jumpers The PCA-6770 has a number of jumpers that allow you to configure your system to suit your application. The table below lists the function of each of the board’s 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, connect the pins with the clip. To “open” a jumper, 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. 1 Open Closed 2 3 Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 Open Closed Closed 2-3 A pair of needle-nose pliers may be helpful when working with jumpers. Setting switches is slightly different but more simple. Simply slide the desired switch to the on or off position. In the example below, the 6 element switch would be. 1:off, 2:on, 3:off, 4:off, 5:off, 6:off. On Off 1 2 3 4 5 6 If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales rep 14 PCA-6770 User's Manual 2.7 CMOS clear function (JP1) Warning: Table 2-3: To avoid damaging the computer, always turn off the power supply before setting "Clear CMOS".

(JP2) An on-board watchdog timer reduces the chance of disruptions which EMP (electro-magnetic pulse) interference can cause. This is an invaluable protective device for standalone or unmanned applications. Setup involves two jumpers and running the control software. (Refer to Appendix A.) When the watchdog timer is enabled and the CPU shuts down, the watchdog timer will automatically either reset the system or generate an interrupt on IRQ 11, depending on the setting of jumper JP2, as shown below: Table 2-4: Watc hdog timer sys tem *System Reset 1 JP2 * default setting 16 PCA-6770 User's Manual reset select (JP2) IRQ 11 interrupt 1 2.9 COM2 settings for RS-232/422/485 (JP5) Table 2-5: COM2 settings for RS-232/422/485 *RS-232 JP3 (JP3) RS-422 RS-485 1 2 1 2 1 2 3 4 3 4 3 4 5 6 5 6 5 6 * default setting 2.10 Power type select (JP3) Table 2-6: Power t ype select ATX Power 1 (JP3) *AT Power 1 JP4 * default setting Chapter 2 Installation 17 2.11 LCD Panel select (JP4) Table 2-9: P anel T ype Select Display (S W1) TYPE Setting (SW1) On 1024 x 768 Dual scan STN Off 1 2 3 4 On 1280 x 1024 TFT color Off 1 2 3 4 On 640 x 480 Dual scan STN Off 1 2 3 4 On 800 x 600 36 bits Dual scan STN Off 1 2 3 4 On 640 x 480 Sharp TFT color Off 1 2 3 4 On 640 x 480 18-bit TFT color Off 1 2 3 4 On 1024 x 768 TFT color Off 1 2 3 4 On 800 x 600 TFT color Off 1 2 3 4 18 PCA-6770 User's Manual 2.12 LCD Panel select (JP4) Table 2-9: Display 800 x 600 P anel Type Select (S W1) TYPE TFT color Setting (SW1) On Off 1 2 3 4 On 800 x 600 TFT color Off 1 2 3 4 On 800 x 600 Dual scan STN color Off 1 2 3 4 On 800 x 600 Dual scan STN color Off 1 2 3 4 On 1024 x 768 TFT color Off 1 2 3 4 On 1280 x 1024 Dual scan STN Off 1 2 3 4 On 1024 x 600 Dual scan STN Off 1 2 3 4 On 1024 x 600 TFT color Off 1 2 3 4 Chapter 2 Installation 19 2.13 Installation Caution The following sections tell how to make each connection. In most cases, you will simply need to connect a standard cable. All of the connector pin assignments are shown in Appendix C. 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 a 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. 20 PCA-6770 User's Manual 2.14 Enhanced IDE Connector (CN1) You can attach two IDE (Integrated Device Electronics) drives to the PCA-6770’s internal controller. The PCA-6770 CPU card has an EIDE connector, CN1. Wire number 1 on the cable is red or blue, and the other wires are gray. Connect one end to connector CN1 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 in 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. Chapter 2 Installation 21 2.15 Parallel Port Connector (CN2) The parallel port is normally used to connect the CPU card to a printer. The PCA-6770 includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN2. The card comes with an adapter cable which lets you use a traditional DB25 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. The parallel port is designated as LPT1, and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup. 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 CN2 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 CN2. Pin 1 is on the right side of CN2. 2.16 ATX Power Connector (CN3) When the PCA-6770 is used as a stand alone card, both the 4-pin main power connector (CN4) and the ATX feature connector (CN3) must be connected to the power supply. If the PCA-6770 is used with a passive backplane, the main power connector (CN4) should not be connected as the card will be powered from the backplane. The ATX adapter cable (provided) is used to connect the PCA6770 to the ATX power supply. The ATX adapter cable has different connectors at both ends. On one end is the ATX 20-pin (female type) which connects to the (male) ATX power supply source. The other end has a 3-pin connector (female type) which connects to the ATX feature connector (CN3) on the board itself. This end also has the 6-pin main power connector (P8) and a 6pin connector (P9) which is used when the board is mounted on a passive backplane. 22 PCA-6770 User's Manual ATX power supply To ATX feature (P8) 6-pin in backplane P8 • P9 (P9) 6-pin in backplane • • • • 20-pin female connector Figure 2-4: ATX Adaptor cable 2.17 AT Power Connector (CN4) If you prefer not to acquire power through PCA-6770’s backplane via the gold H-connectors, CN4 also provides power input connectors for +5 V and +12 V. (see Appendix C) 2.18 LCD Inverter Connector (CN5) The LCD inverter is connectoed to CN5 via a 5-pin connector to provide +12 V power to the LCD display. The pin assignments for CN5 can be found in Appendix C. Chapter 2 Installation 23 2.19 Floppy Drive Connector (CN6) You can attach up to two floppy disk drives to the PCA-6770’s onboard 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. 2.20 Reset switch (CN7) If you install a reset switch, it should be a single pole switch rated at 10 mA, 5 V. Momentarily pressing the switch will activate a reset.

Note: PCA-6770 card only supports SDRAM SODIMM modules. EDO SODIMM is not supported. 2.37.1 Installing SODIMMs Note 1:The modules can only fit into a socket one way. Their gold pins must point down into the SODIMM socket. Please refer to the diagram for dimensions. 30 PCA-6770 User's Manual The procedure for installing SODIMMs appears below. Please follow these steps carefully. 1. Ensure that all power supplies to the system are switched Off. 2. Install the SODIMM card. Install the SODIMM so that its gold pins point down into the SODIMM socket. 3. Slip the SODIMM into the socket at a 45 degree angle and carefully fit the bottom of the card against the connectors. 4. Gently push the SODIMM into a perpendicular position until the clips on the ends of the SODIMM sockets snap into place. 5. Check to ensure that the SODIMM is correctly seated and all connector contacts touch. The SODIMM should not move around in its socket. Figure 2-5: Standard SODIMM Dimensions Note 2: Only use Standard Form SODIMM memory modules (As shown in the dimensions above). Standardized dimensions ensure a proper fit. Check with your Memory supplier about the SODIMM modules you will use. Chapter 2 Installation 31 2.38 CPU installation and upgrading 1. If you are upgrading the CPU, remove the old CPU from the socket. If it is difficult to remove, you may find chip lubricant (designed for pin-grid-array devices, PGAs) and a chip puller helpful. Both are available at electronics hobby supply stores. 2. Plug 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 CPU pins with lubricant made for PGA devices. This will make the new CPU slide in much more easily, and reduce the chance of damaging it. Next, carefully align the CPU so that it is parallel to the socket and the notch on the corner of the CPU corresponds with the notch on the inside of the socket. Gently slide the CPU in. There will probably be a gap between the CPU and the connector when it is fully seated - do not push too hard! 32 PCA-6770 User's Manual CHAPTER 3 Award BIOS Setup This chapter describes how to set the card’s BIOS configuration data. 3.1 AWARD BIOS Setup Figure 3-1: Setup program initial screen Award’s BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration.
