Introduction

The PCI-7200, cPCI-7200, and LPCI-7200S are PCI/CompactPCI/Low profile
PCI form factor high-speed digital I/O cards, consisting of 32 digital input
channels, and 32 digital output channels. High performance design and
state-of-the-art technology make this card suitable for high-speed digital input
and output applications.

The PCI-7200 performs high-speed data transfers using bus-mastering DMA
via the 32-bit PCI bus architecture. The maximum data transfer rates can be
up to 12MB per second—very suitable for interfacing high-speed peripherals
and your computer system.

Several different digital I/O operation modes are supported:

1. Direct Program Control:

and controlled by its corresponding I/O ports directly.

2. Timer Pacer Mode:

internal timer pacer clock and transferred by bus mastering DMA.

3. External Clock Mode:

external input strobe signal (I_REQ) and transferred by bus mastering DMA.

4. Handshaking:

simple handshaking data transfer.

through the REQ and ACK signals, digital I/O data can utilize

Installation

This chapter describes how to install the PCI-7200. Package contents and
unpacking information are described. Because the PCI-7200 is a Plug and
Play device, there are no more jumper or DIP switch settings for configuration.
The interrupt number and I/O port address are assigned by the system BIOS
during system boot up.

2.1 What Included

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

 PCI-7200 Digital I/O & Counter Card

 ACL-10437: 40-pin to 37-pin D-Sub cable

or

 cPCI-7200 Digital I/O & Counter Module for 3U CompactPCI

 100-pin SCSI connector assembly

or

 LPCI-7200S Low profile Digital I/O & Counter Card

 Two 68-pin SCSI connectors assembly

 ADLINK CD

 Software Installation Guide

If any of these items is missing or damaged, contact the ADLINK dealer. Save
the shipping materials and carton to ship or store the product in the future.

Installation • 7

2.2 Unpacking

The PCI-7200 card contains sensitive electronic components that can be
easily damaged by static electricity.

The work area should have 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 the module. Be sure there is no shipping and handling
damage on the module before proceeding.

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-7200.

2.3 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 installing NuDAQ/NuIPC cards in this system, Windows will require device

information source. Please refer to the “Software Installation Guide” for the

steps of installing the device.

2.5 Hardware Installation Outline

Hardware configuration

These PCI cards (or CompactPCI, Low Profile PCI cards) are equipped with a
Plug and Play PCI controller that requests base addresses and interrupts
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 and Low-Profile PCI cards can be inserted to any PCI slot without any
configuration for system resource. CompactPCI peripheral slots are marked
with a circle on the backplane. Please note that the PCI, CompactPCI, and
Low-Profile PCI system board must provide bus-mastering capability to
operate this board well.

Installation Procedures

1. Turn off the computer

2. Turn off all accessories (printer, modem, monitor, etc.) connected to the
computer

3. Remove the cover from your computer

4. Select a 32-bit PCI slot. PCI slot are short than ISA or EISA slots, and are
usually white or ivory

5. Before handling the PCI cards, discharge any static buildup on your body by
touching the metal case of the computer. Hold the edge of the card and do
not touch the components

6. Position the board into the PCI selected slot.

7. Secure the card in place at the rear panel of the system

2.6 Connector Pin Assignments

2.6.1 PCI-7200 Pin Assignments

The PCI-7200 comes equipped with one 37-pin D-Sub connector (CN2)
located on the rear mounting plate and one 40-pin female flat cable header
connector (CN1). The CN2 is located on the rear mounting plate; the CN1 is on
front of the board. Refer section 2.4 PCI-7200‘s layout.

CN2 is used for digital inputs (DI 0 to DI 15) and digital outputs (DO 0 to DO 15)
The reminding digital I/O channels DI 16 to DI 31 and DO 16 to DO 31 are on
CN1. The pin assignment of CN1 and CN2 is illustrated in the Figures 2.2 and
