Product Warranty (2 years)

Advantech warrants to you, the original purchaser, that each of its prod-

ucts will be free from defects in materials and workmanship for two years

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 instal-

lation. 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 test-

ing, 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, CPU speed, Advantech products used, other hardware

and software used, etc.) Note anything abnormal and list any

onscreen messages you get when the problem occurs.

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

ual, product, and any helpful information readily available.

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

merchandize 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 war-

ranty service.

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

ship it prepaid to your dealer.

Chapter 1 Introduction

The PCL-722 144 bit DIO card is a generalized 144 line parallel digital I/

O board that has six channels. Each channel emulates mode 0 of a 8255

programmable peripheral interface chip, and has 24 lines of digital input

and/or output. Every channel has an individual connector with OPTO-22

compatible pin assignment. Two lines of each connector can be used to

generate a hardware interrupt. These inputs are buffered and can be con-

nected to IRQ 2, 3, 4, 5, 6 and 7. The PCL-722 is a full-size PC add-on

card and can fit any full-length expansion slot in the IBM PC XT/AT or

compatible computer running at any clock rate.

1.1 Features

• 144 TTL digital I/O lines, (6 connectors, each with 24 I/O lines)

• The 24 I/O lines of each connector are configured to port PA (8 bit), PB

(8 bit), PC Upper (4 bit) and PC Lower (4 bit). Each port can be pro-

grammed to digital input or digital output

• Emulates mode 0 of 8255 PPI

• Programmable interrupt handling

• OPTO-22 compatible 50-pin connector

• Direct interface to wide range of peripherals

1.2 Specifications

1.2.1 Digital Input

Channels: 144 (24 channels x 6 ports) shared with output

Compatibility: 5V/TTL

Input Voltage: Logic 0: 0.0 V ~ 0.80 V @ -0.2 mA

Logic 1: 2.0 V ~ 5.25 V @ 20 uA
