Product Warranty

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.

Initial inspection

Before you begin installing your card, please make sure that the following materials have been shipped:

• 1 PCA-6175 Pentium® II single board computer

• 1 Pentium II CPU and cooling fan (optional)

• 1 PCA-6175 user's manual

• 1 bus master & BIOS utility driver

• 1 FDD cable

• 2 EIDE HDD cables

• 1 printer cable

• 1 ivory cable for keyboard and mouse

• 1 ATX-to-PS/2 power cable

• 1 Pentium II CPU retention module If any of these items are missing or damaged, contact your

distributor or sales representative immediately. We have carefully inspected the PCA-6175 mechanically and

electrically before shipment. It should be free of marks and scratches and in perfect working order upon receipt.

As you unpack the PCA-6175, check it for signs of shipping damage. (For example, damaged box, scratches, dents, etc.) If it is damaged or it fails to meet the specifications, notify our service department or your local sales representative immediately. Also notify the carrier. Retain the shipping carton and packing material for inspection by the carrier. After inspection, we will make arrangements to repair or replace the unit.

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. Try to 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.

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.

1.5 Jumpers and Connectors

Connectors on the PCA-6175 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.

1.8 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:
