Introduction

The PCI-7396 is a 48/96-bit parallel digital input/output (DIO) card designed
for industrial applications. The plug and play feature of PCI-Bus architecture
make it easy for users to install their systems quickly.

The PCI-7396 emulates two/four 8255 Programmable Peripheral Interface
(PPI) chips. Each PPI offers 3 8-bit DIO ports which can be accessed
simultaneously. The total 6/12 ports can be programmed as input or output
independently.

The PCI-7396 supports external trigger to latch the digital input data. The
function of “Change of State” (COS) interrupt is provided. It means when
anyone of these digital inputs changes its state, an interrupt will be generated
for user to handle this external event.

1.1 Features

The PCI-7396 Digital I/O boards provide the following advanced features:

1.1.1 Digital I/O Ports

u 48/96 TTL compatible digital I/O lines
u SCSI-type 100-pin connector (AMP-787082-9)
u 48mA High current driving capability per channel
u Output status read-back
u Support external trigger to latch digital input data (PCI-7348 only)

Introduction • 1

1.1.2 Timer / Counter and Interrupt System

u A programmable 32-bit timer to generate timer interrupt
u A programmable 16-bit event counter to generate event interrupt
u 48/96-bit change of state (COS) interrupt
u Dual interrupt system

1.1.3 Miscellaneous

u Provide 12V and 5V power supply on SCSI-type 100-pin

connectors(only for PCI-7348)

u On board resettable fuses to protect power supply from external

damage. (only for PCI-7348)

1.2 Applications

u Programmable mixed digital input & output
u Industrial monitoring and controlling
u LED indicator driving
u Parallel data transfer
u TTL,DTL, and CMOS logic sensing

Installation • 7

2.2 Unpacking

Your PCI-7396 card contains sensitive electronic components that can be
easily damaged by static electricity.

The card should be done 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.

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, exact the system module and place it
only on a grounded anti-static surface component side up.

Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN

DAMAGED.

You are now ready to install your PCI-7396.

2.4 Hardware Installation Outline

Hardware configuration

The PCI cards (or CompactPCI cards) are equipped with plug and play PCI
controller, it can request base addresses and interrupt according to PCI
standard. The system BIOS will install the system 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 assignments are done on a board-by-board basis. It is not
suggested to assign the system resource by any other methods.

PCI slot selection

The PCI card can be inserted to any PCI slot without any configuration for
system resource.

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.
