CHAPTER

Hardware Configuration

This chapter gives background information on the PCA-6175. 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

1.1 Introduction

The PCA-6175 industrial grade CPU card uses Intel's highly acclaimed Pentium® II processor and Intel 440LX PCI chipset. The card works with standard ISA or PCI/ISA-bus passive backplanes.

The CPU provides 512 KB on-chip L2 cache, eliminating the need for external SRAM chips. It has two PCI EIDE interfaces (for up to four devices), and an FDD 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 EPP/ECP), and support for two USB (Universal Serial Bus) ports. The PCI BUS Master IDE controller supports Ultra DMA/33 operation. This provides data transfer rates of over 33 MB/sec, and allows drive capacities up to 8.4 GB. System BIOS supports boot-up from an IDE CD-ROM.

A backup of CMOS data is stored in the Flash memory, which protects data even after a battery failure. Also included is a 63-level watchdog timer, which resets the CPU or generates an interrupt if a program cannot be executed normally. This enables reliable operation in unattended environments.

1.8 Safety Precautions

Warning! Always completely disconnect the pow er cord from

your chassis whenever y ou work with the hardware . Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. Only experienced electronics personnel should open the PC chassis.

Caution! Always ground y ourself to remove any static charge

before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. As a safety precaution, use a grounding wrist strap at all times. Place all electronic components in a static-dissipative surface or static-shielded bag when they are not in the chassis.

Chapter 1 Hardware Configuration

1.9 Jumper Settings

This section provides instructions on how to configure your card by setting jumpers. It also includes the card's default settings and your options for each jumper.

1.9.1 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 consists of a set of three pins, labeled 1, 2 and 3. In this case you connect either pins 1 and 2, or 2 and 3.

A pair of needle-nose pliers may be useful when setting jumpers.

1.9.2 CPU core frequency (J5)

You must configure your PCA-6175 CPU card to the frequency of your Intel Pentium® II processor by setting jumper J5. The PCA-6175 is equpped to use Pentium processors with speeds of 233, 266, 300 and 333 MHz. Configure your PCA-6175 as follows:

1.9.3 CMOS clear (J6)

The PCA-6175 CPU card contains a jumper that can erase CMOS data and reset the system BIOS information. Normally this jumper should be set with pins 1-2 closed. If you want to reset the CMOS data, set J6 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed. This procedure will reset the CMOS to its default setting.

Table 1-4: CMOS clear jumper settings (J6)

Function Jumper setting

Keep CMOS data 1-2 closed

Clear CMOS data 2-3 closed

1.9.4 Watchdog timer output (J8)

The PCA-6175 contains a watchdog timer that will reset the CPU or send a signal to IRQ11 in the event the CPU stops processing. This feature means the PCA-6175 will recover from a software failure or an EMI problem. The J8 jumper settings control the outcome of what the computer will do in the event the watchdog timer is tripped.

Chapter 1 Hardware Configuration

1.10 System Memory

The top-left edge of the PCA-6175 contains three sockets for 168-pin dual inline memory modules (DIMMs). All three sockets use 3.3 V unbuffered synchronous DRAMs (SDRAM). DIMMs are available in capacities of 16, 32, 64 or 128 MB. The sockets can be filled in any combination with DIMMs of any size, giving your PCA-6175 single board computer between 16 and 384 MB of memory. Use the following table to calculate the total DRAM memory within your computer:

Table 1-8: DIMM module allocation table

Socket number 168-pin DIMM memory

1 (8, 16, 32, 64 or 128 MB) x 1 2 (8, 16, 32, 64 or 128 MB) x 1 3 (8, 16, 32, 64 or 128 MB) x 1

1.10.1 Sample calculation: DIMM memory capacity

Suppose you install a 128 MB DIMM into your PCA-6175's socket 1, a 32 MB DIMM into socket 2, and you leave socket 3 empty . Your total system memory is calculated as follows, and is 160 MB:

Table 1-9: DIMM memory capacity sample calculation

Socket number 168-pin DIMM memory Total memory

1 128 MB x 1 128 MB 2 32 MB x 1 32 MB 3- x 1 0 MB

Total memory 160 MB

PCA-6175 User's Manual

1.10.2 Supplementary information about DIMMs

Your PCA-6175 can accept four kinds of memory chips: EDO (with or without parity), and SDRAM (with or without parity). Also:

• SDRAM chips are usually thinner and have higher pin density than

EDO chips.

• The BIOS displays EDO and SDRAM memory on the boot-up

screen.

• Chips with 9 chips/side support parity; chips with 8 chips/side do not

support parity .

• Single-sided modules are typically 16 or 64 MB; double-sided

modules are usually 8, 32 or 128 MB.

Note: The PCA-6175 accepts EDOs both with and without

parity , b ut this is not recommended.

Chapter 1 Hardware Configuration

1.11 Memory Installation Procedures

T o install DIMMs, first make sure the two handles of the DIMM socket are in the "open" position. i.e. The handles remain outward. Slowly slide the DIMM module along the plastic guides on both ends of the socket. Then press the DIMM module right down into the socket, until you hear a click. This is when the two handles have automatically locked the memory module into the correct position of the DIMM socket. (See Figure 1-3.) T o take away the memory module, just push both handles outward, and the memory module will be ejected by the mechanism in the socket.

PCA-6175 User's Manual

Figure 1-3: DIMM installation

1.12 Cache Memory

Since the second level cache has been embedded into the Pentium® II CPU, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the Pentium II yields much higher performance than the external cache memories. The cache size in the Pentium II CPU is either 256 KB or 512 KB. Normally, for workstation and server application, the 256 KB version is enough. However, if your system is for heavy duty applications, the 512 KB version will help a lot. Specifically for our Pentium II based SBC, the Pentium II has another version that provides much better data security if combined with the DRAM ECC. Check with your vendor for various Pentium II models.

Chapter 1 Hardware Configuration

1.13 Mounting the CPU and Cooling Modules

The Pentium® II is a module-type CPU which runs at high speeds, for exampe 233 ~ 333 MHz, so the cooling mechanism becomes critical for system reliability. There are two types of cooling methods: one with a cooling fan attached to the heat sink of the Pentium II module, the other with a huge heat sink without any cooling fan attached.

Both cooling methods for the Pentium II require a "retention module" to firmly fix the Pentium II CPU to slot 1. The following Figures 1-4 through 1-6 illustrate the steps involved in mounting the retention module and installing the CPU and cooling modules.

CHAPTER

Connecting Peripherals

This chapter tells how to connect peripherals, switches and indicators to the PCA-6175 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.

2.1 Primary (CN6) and Secondary (CN7) IDE Connectors

You can attach up to four IDE (Integrated Device Electronics) drives to the PCA-6175’s internal controller. The primary (CN6) and secondary (CN7) connectors can each accommodate two drives.

Wire number 1 on the cable is red or blue and the other wires are gray. Connect one end to connector CN6 or CN7 on the CPU card. Make sure that the red/blue wire corresponds to pin 1 on the connector (in the upper right hand corner). 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 to a single connector, 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 per connector, you should set each drive 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 hard drive to the remaining connector (CN7 or CN6), in the same way as described above.

2.2 Floppy Drive Connector (CN13)

You can attach up to two floppy disk drives to the PCA-6175'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 drive. The set in the middle connects to the B: floppy drive.

PCA-6175 User's Manual

2.3 Parallel Port Connector (CN8)

The parallel port is normally used to connect the CPU card to a printer. The PCA-6175 includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN8. 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.

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 CN8 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 CN8. Pin 1 is on the upper right side of CN8.

2.4 Keyboard & PS/2 Mouse Connector (CN12)

The PCA-6175 board provides a keyboard connector. A 6-pin mini-DIN connector (CN12) 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.

Chapter 2 Connecting Peripherals

2.5 Serial Ports (CN9: COM1; CN10: COM2)

The PCA-6175 offers two serial ports, CN1 as COM1 and CN2 as COM2. These ports can connect to serial devices (such as a mouse, printers, and so on) or to a communication network.

Table 2-1: Serial port connections (COM1, COM2)

Connector Ports Address Interrupt

CN9 COM1 3F8*, 3E8 IRQ4 CN10 COM2 2F8*, 2E8 IRQ3

* default settings The IRQ and address ranges for both ports are fixed. However, if you

want to disable the port or change these parameters later, you can do this in the system BIOS setup.

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.

2.6.5 Reset (J2)

Many computer cases offer the convenience of a reset button. Connect the wire from the reset button to J2.

Chapter 2 Connecting Peripherals

2.7 ATX Power Control Connectors (J7 and J1)

2.7.1 ATX feature connector (J7) and soft power switch connector (J1)

The PCA-6175 can support an advanced soft power switch function if an ATX power supply is used. To enable the soft power switch function:

1. Take the specially designed ATX-to-PS/2 power cable out of the

PCA-6175's accessory bag.

2. Connect the 3-pin plug of the cable to J7 (ATX feature connector).

3. Connect the power on/off button to J1. (A momentary type of

button should be used.)

Important: Be sure that the ATX pow er supply can take at least

a 10 mA load on the 5 V standby lead (5VSB). If not, you may ha v e difficulty po wering on your system.

Figure 2-1: Wiring for ATX soft power switch function

PCA-6175 User's Manual

2.7.2 Controlling the soft power switch

It is easy to control the ATX soft power switch. Pushing the button once will switch the system between the "On" and "Suspend" power modes. Pushing the button for more than 4 seconds while in the "On" mode will turn the system off. Users can also identify the current power mode through the system's power LED, as indicated below:

ATX Power Mode LED Status System On On System Suspend Flashes eight times/sec. System Off Flashes once/sec.

2.8 USB Connector (CN11)

The PCA-6175 CPU card provides two USB (Universal Serial Bus) interfaces, which give complete plug and play, hot attach/detach for up to 127 external devices.The USB interfaces comply with USB Specification Rev. 1.0, and are fuse-protected.

The USB interfaces are accessed through a 10-pin flat-cable connector, CN11. The adapter cable has a 10-pin connector on one end and a USB connector on the bracket.

The USB interfaces can be disabled in the system BIOS setup.

2.9 IR Connector (CN1)

This connector supports the optional wireless infrared transmitting and receiving module. This module mounts on the system case. You must configure the setting through the BIOS setup.

2.10 External Keyboard Connector (J10)

In addition the the PS/2 mouse/keyboard connector on the PCA6175's rear plate, there is also an extra on-board external keyboard connector. This gives system integrators greater flexibility in designing their systems.

Chapter 2 Connecting Peripherals

2.11 External Suspend Switch Lead (SMI) (J3)

This allows the user to manually place the system into a suspend mode or "Green" mode when the system is not in use. System activity is decreased to save electricity and prolong the life of certain components. The 2-pin connector connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the "turbo switch", because it does not have any other function. SMI is activated when it detects a "short to open" moment. Therefore, leaving it shorted will not cause any problems. It may require one or two pushes depending on the position of the switch. Wake-up can be controlled by settings in the BIOS, but the keyboard will always allow wake-up. (The SMI lead cannot wake up the system.) If you want to use the SMI connector, the "Suspend" switch in the Power Management Setup of the BIOS software should be on the default setting "Enable".
