Introduction

cPCI/PCI-8554/R is a general-purpose counter / timer and digital I/O card.
The card is designed with four 8254, a programmable interval
timer/counter chip, totally, providing twelve 16-bit down counter or
frequency dividers. Three different types of interface are available: PCI
(PCI-8554), CompactPCI (cPCI-8554), and CompactPCI with rear I/O
connection (cPCI-8554R) for various platforms and applications.

The card has multi-configurations. Its counters can be set in an
independent or cascaded configuration. The gate controls for the counter
can come from either the internal default enable signal or from external
sources. The clock source of the counters can be set from an internal or
external clock source, when an external clock source is used, users can
configure the jumper as to disable or enable the debounce function.

The card also provides digital input and output ports. There are 8 digital
output and 8 digital input channels, which can be used to control or
monitor external devices.

The cPCI/PCI-8554/R provides an interrupt signal, which is generated by
the counter output. External interrupt signals can also be used. The
interrupt can be used for watchdog timers or others applications. The
maximum interrupt time interval can be 536 seconds.

The I/O signals are provided via the 100-pin SCSI-II connector. Figure 1
shows the functional block diagram of the cPCI/PCI-8554/R. The
cPCI/PCI-8554/R uses ASIC PCI controller to interface the board to the
PCI bus. The ASIC fully implements the PCI local bus specification Rev

2.1. The BIOS software automatically controls all bus relative
configurations, such as base memory and interrupt assignment. This
removes the burden of searching for a conflict, which can be very time
consuming and difficult with some bus standards.

Getting Started

This chapter discusses how to setup the cPCI/PCI-8554R and configure
the card to meet the requirements of your application. The contents of the
package and unpacking information that you should be aware off are
outlined first.

2.1 What You Have

In addition to this User's Manual, the package should includes the
following items:

cPCI/PCI-8554/R Enhanced Multi-function Counter / Timer

•

Card

ADLINK CD

•

Software Installation Guide

•

If any of these items are 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 cPCI/PCI-8554/R card contains electro-static sensitive components
that can be easily be damaged by static electricity.

Therefore, the card should be handled 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.

Getting Started •7

Inspect the card module carton for obvious damages. Shipping and
handling may cause damage to your module. Be sure there are no
shipping and handling damages on the modules carton before continuing.

After opening the card module carton, extract the system module and
place it only on a grounded anti-static surface with component side up.

Again, inspect the module for damages. Press down on all the socketed
IC's to make sure that they are properly seated. Do this only with the
module placed 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 cPCI/PCI-8554/R.

2.4 Default Jumper Setting

To operate the cPCI/PCI-8554/R correctly, users need to understand the
structure of cPCI/PCI-8554/R and details of the possible configurations.
The functional block diagram of the cPCI/PCI-8554/R is shown in figure 1
of chapter 1. The following section lists the default jumper setting on the
cPCI/PCI-8554/R.

Items Default Configuration Set by

ECLK1 No Debounce function JP1

ECLK2 No Debounce function JP2

ECLK3 No Debounce function JP3

ECLK4 No Debounce function JP4

ECLK5 No Debounce function JP5

Table 2. Extra Default Jumper Setting on cPCI-8554/R

There are 13 jumpers available on the PCI-8554, and 15 jumpers on the
cPCI-8554/R, the first 11 jumpers are used to select the debounce function.
JP12 and JP13 are used for selecting the clock source for Counter No. 11
and 12. The default setting for counter No. 11 and 12 are cascaded for
frequency division. Refer to section 2.9 for more details. JP14 and JP15
are used for selecting the gate voltages of counter No. 11 and 12 (only for
cPCI-8554/R). Users can change the cPCI/PCI-8554/R's default
configuration by setting jumpers on the card to suit the application. 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
theory are not discussed in this chapter. Refer to section 2.12 for details
of the operation theory and than refer to chapter 4 for application notes.

2.5 cPCI/PCI-8554/R Installation

2.5.1 Hardware configuration

The PCI cards (or CompactPCI cards) is equipped with the plug and play
PCI controller, it has the ability to request base addresses and interrupts
according to the PCI standard. The systems BIOS will install the system
resources based on the PCI cards’ configuration registers and system
parameters (which are set by system BIOS). Interrupt assignments and
memory usage (I/O port locations) of the PCI cards are also assigned by
system BIOS. This system resource assignment is done on a board-by­board basis. It is not suggested to assign system resources by any other
methods.

The PCI card can be inserted into any PCI slot without the need for any
system resource configuration.

2.5.1.1 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 shorter than ISA or
EISA slots, and are usually white or ivory in color.

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.
