How to Use This Guide •iii
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.

Installation
This chapter describes the configurations and multi-functions of the
PCI-8554 and teach user to install PCI-8554. At first, the contents in
the package and unpacking information that you should care about
are described, then versatile configurations of PCI-8554 are
introduced so that you can configure it according to your applications.
The default jumper setting of PCI-8554 is shown in this chapter also.
2.1 What You Have
In addition to this User's Manual, the package includes the following
items:
•PCI-8554 Enhanced Multi-function Counter / Timer Card
•ADLINK CD
•Software Installation Guide
If any of these items is missing or damaged, contact the dealer from
whom you purchased the product. Save the shipping materials and
carton in case you want to ship or store the product in the future.
2.2 Unpacking
Your PCI-8554 card contains sensitive electronic components that
can be easily damaged by static electricity. The card should be
unpacked on a grounded anti-static mat. The operator should be
wearing an anti-static wristband, grounded at the same point as the
anti-static mat.

Installation •9
Inspect the card module carton for obvious damage. Shipping and
handling may cause damage to your module. Be sure there are no
shipping and handing damages on the module before processing.
After opening the card module carton, extract the system module and
place it only on a grounded anti-static surface component side up.
Again inspect the module for damage. Press down on all the
socketed IC's to make sure that they are properly seated. Do this
only with the module place on a firm flat surface.
Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your PCI-8554.

2.4 Default Jumper Setting
To operate the PCI-8554 correctly, users should understand the
structure of PCI-8554 and details of the possible configurations. The
block diagram of the PCI-8554 is shown in chapter 1. It contains the
clock system, counters confederation, interrupt system and PCI
controller. The following sections teach you the jumper setting and the
default setting listed in Table 2.1.
Items Default Configuration Setting by:
ECLK1 Debounce function JP1
ECLK2 Debounce function JP2
ECLK3 Debounce function JP3
ECLK4 Debounce function JP4
ECLK5 Debounce function JP5
ECLK6 Debounce function JP6
ECLK7 Debounce function JP7
ECLK8 Debounce function JP8
ECLK9 Debounce function JP9
ECLK10 Debounce function JP10
E_INT Debounce function JP11
Table 2.1 Default Configuration of PCI-8554
There are eleven jumpers on PCI-8554, these jumpers are used to
select debounce function. You can change PCI-8554's default
configuration by setting jumpers on the card for your own
applications. The card's jumpers are preset at the factory.
Before changing the default configuration, users must fully
understand the operation of the debounce function. The setting and
the basic operation theorem are not discussed in this chapter. It is
recommended to refer chapter 2.12 for details of the operation
theorem and to refer chapter 4 for application notes.

resource based on the PCI cards’ configuration registers and system
parameters (which are set by system BIOS). Interrupt assignment and
memory usage (I/O port locations) of the PCI cards can be assigned by
system BIOS only. These system resource assignment is done on a
board-by-board basis. It is not suggested to assign the system
resource by any other methods.
1. PCI slot selection
The PCI card can be inserted to any PCI slot without any configuration
for system resource.
2. Installation Procedures
1. Turn off your computer
2. Turn off all accessories (printer, modem, monitor, etc.)
connected to your computer.
3. Remove the cover from your computer.
4. Setup jumpers on the PCI or CompactPCI card.
5. Select a 32-bit PCI slot. PCI slot are short than ISA or EISA slots,
and are usually white or ivory.
6. Before handling the PCI cards, discharge any static buildup on
your body by touching the metal case of the computer. Hold the
edge and do not touch the components.
7. Position the board into the PCI slot you selected.
8. Secure the card in place at the rear panel of the system.
2.6 Device Installation for Windows Systems
Once Windows 95/98/2000 has started, the Plug and Play function of
Windows system will find the new NuDAQ/NuIPC cards. If this is the
first time to install NuDAQ/NuIPC cards in your Windows system, you
will be informed to input the device information source. Please refer to
the “Software Installation Guide” for the steps of installing the device.
