How to Use This Guide
This manual is designed to help you use the PCI-8554. The manual
describes how to modify various settings on the PCI-8554 card to
meet your requirements. It is divided into 5 chapters:
•Chapter 1, "Introduction," gives an overview of the product features,
applications, and specifications.
•Chapter 2, "Installation & Configurations" describes the operation
method and multi-functions of the PCI-8554. Users should read
through this chapter to understand the configurations of the PCI-
8554. The chapter will also teach user how to install the PCI-8554.
•Chapter 3, "Register Format," describes the details of register
format of the PCI-8554, this information is very useful for the
programmers who want to control the hardware by low level
programming.
•Chapter 4, "Signal Connection & Applications,” describes the
connectors' pin assignment and how to connect the outside signal
and devices to / from the PCI-8554. Some applications also are
introduced.
•Chapter 5, "High-level Programming," introduces the C-language
library for operating the PCI-8554. Some examples are shown too.

Introduction
PCI-8554 is a general-purpose counter / timer and digital I/O card.
This card have four 8254 chips on board, so it provides twelve 16
bits down counter or frequency dividers.
This card has multi-configurations. The counters can be set as
independent counter or cascaded counter. The gate control of
counter come from either external source or internal default enable
signal. The clock source of the counters can be set as internal or
external clock source, when external clock is used, user can set the
jumper to decide whether the debounce function is used or not used.
An 8 MHz crystal is used as internal clock source. It is possible to
use this card on variety of powerful counter / timer functions to match
your industry and laboratory applications. Users can set the
configuration to fit the variety of applications.
The card also provides digital output and input port. There are 8 bits
digital output and 8 bits digital input channels which can be used to
control or monitor the external devices.
PCI-8554 provides one interrupt signalwhich comes from internal or
external interrupt sources, the internal interrupt sources come from
the counter output. The interrupt can be used for watchdog timer or
others applications. The maximum interrupt time interval can be 536
sec.
The I/O signals are via a 100 pin SCSI-II connector that project
through the computer case at the rear of the board. The figure 1.1
shows the block diagram of the PCI-8554.

2•Introduction
PCI-8554 uses ASIC PCI controller to interface the board to the PCI
bus. The ASIC fully implementthe PCI local bus specification Rev 2.0.
All bus relative configurations, such as base memory and interrupt
assignment, are automatically controlled by BIOS software. It does
not need any user interaction and pre-study for the configurations.
This removes the burden of searching for a conflict-free configuration,
which can be very time consuming and difficult with some other bus
standards.

1.1 Features
The PCI-8554 Counter / Timer and digital I/O Card provides the
following advanced features:
•Four 8254 chips provide twelve 16 bits down counters
•Multi-configurations of counters / timers:
•Flexible setting for each independent counter, the clock source
could be external, internal or cascaded. The gate signal is
external controlled or internal enabled.
•Provide debounce function with flexible setting to prevent from
bounce phenomenon when using external clock.
•8 digital output channels
•8 digital input channels
•Dual interrupt sources
The first interrupt source comes from output of counter#12
