Advantech warrants to you, the original purchaser, that each of its products will be free from defects in materials and workmanship for one year from the date of purchase.

This warranty does not apply to any products which have been repaired or altered by persons other than repair personnel authorized by Advantech, or which have been subject to misuse, abuse, accident or improper installation. Advantech assumes no liability under the terms of this warranty as a consequence of such events.

Because of Advantech’s high quality-control standards and rigorous testing, most of our customers never need to use our repair service. If an Advantech product is defective, it will be repaired or replaced at no charge during the warranty period. For out-of-warranty repairs, you will be billed according to the cost of replacement materials, service time and freight. Please consult your dealer for more details.

If you think you have a defective product, follow these steps:

1. Collect all the information about the problem encountered. (For

example, type of PC, CPU speed, Advantech products used, other hardware and software used, etc.) Note anything abnormal and list any on-screen messages you get when the problem occurs.

2. Call your dealer and describe the problem. Please have your

manual, product, and any helpful information readily available.

3. If your product is diagnosed as defective, obtain an RMA (return

material authorization) number from your dealer. This allows us to process your return more quickly .

4. Carefully pack the defective product, a fully-completed Repair and

Replacement Order Card and a photocopy proof of purchase date (such as your sales receipt) in a shippable container. A product returned without proof of the purchase date is not eligible for warranty service.

5. Write the RMA number visibly on the outside of the package and

ship it prepaid to your dealer.

CHAPTER

Hardware Configuration

This chapter gives background information on the PCA-6275. 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-6275 industrial grade CPU card uses two of Intel's highly acclaimed Pentium® II processors, together with the Intel 440BX 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. System BIOS supports boot-up from an IDE CD-ROM, SCSI CD-ROM and LS-120.

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.

1.5 Jumpers and Connectors

Connectors on the PCA-6275 board link it to external devices such as hard disk drives and a keyboard. In addition, the board has a number of jumpers used to configure your system for your application.

The tables below list the function of each of the board jumpers and connectors. Later sections in this chapter give instructions on setting jumpers. Chapter 2 gives instructions for connecting external devices to your card.

1.7 Safety Precautions

Warning! Always completely disconnect the power 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 remo v e 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.

PCA-6275 User's Manual

1.8 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.

1.8.1 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. T o “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

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

1.8.2 CPU core frequency (J1)

You must configure your PCA-6275 CPU card to the frequency of your Intel Pentium® II processor by setting jumper J1. The PCA-6275 is equpped to use Pentium processors with speeds of 233, 266, 300, 333, 350, 400, 450, and 500 MHz. Configure your PCA-6275 as follows:

1.8.3 Watchdog timer output (J2)

The PCA-6275 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-6275 will recover from a software failure or an EMI problem. The J2 jumper settings control the outcome of what the computer will do in the event the watchdog timer is tripped.

Table 1-4: Watchdog timer output (J2)

Function Jumper setting

IRQ11 1-2 closed

Reset 2-3 closed

1.8.4 CMOS clear (J4)

The PCA-6275 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 J4 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.

Keep CMOS data 1-2 closed

Clear CMOS data 2-3 closed

Chapter 1 Hardware Configuration

1.9 System Memory

The top-left edge of the PCA-6275 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, 128, or 256 MB. The sockets can be filled in any combination with DIMMs of any size, giving your PCA-6275 single board computer between 16 and 768 MB of memory. Use the following table to calculate the total DRAM memory within your computer:

Table 1-6: DIMM module allocation table

Socket number 168-pin DIMM memory

1 (16, 32, 64, 128 or 256 MB) x 1 2 (16, 32, 64, 128 or 256 MB) x 1 3 (16, 32, 64, 128 or 256 MB) x 1

1.9.1 Sample calculation: DIMM memory capacity

Suppose you install a 128 MB DIMM into your PCA-6275's socket 1, a 32 MB DIMM into socket 2, and you leave socket 3 empty. Your total system memory is 160 MB, calculated as follows:

Table 1-7: 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-6275 User's Manual

1.9.2 Supplementary information about DIMMs

Your PCA-6275 can accept SDRAM memory chips (with or without parity). Also note:

• If the PCA-6275 operates at 100 MHz, only use PC100-

compliant DIMMs. Most systems will not even boot if noncompliant modules are used. This is due to strict timing issues involved st this speed.

• SDRAM chips are usually thinner and have higher pin

density than EDO chips.

• Chips with 9 chips/side support ECC; chips with 8 chips/

side do not support ECC.

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

sided modules are usually 8, 32, 128, or 256 MB.

Chapter 1 Hardware Configuration

1.10 Memory Installation Procedures

To 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 1-2.) To take away the memory module, just push both handles outward, and the memory module will be ejected by the mechanism in the socket.
