1 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 with your computer system.

Several different digital I/O operation modes are supported:

1. Direct Program Control: the digital inputs and outputs

can be accessed and controlled by its corresponding I/O
ports directly.

2. Timer Pacer Mode: the digital input and output opera-

tions are handled by internal timer pacer clock and trans­ferred by bus mastering DMA.

3. External Clock Mode: the digital input operations are

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

4. Handshaking: through the REQ and ACK signals, digi-

tal I/O data can utilize simple handshaking data transfer.

2 Installation

This chapter describes how to install the PCI-7200. Package con­tents and unpacking information are described. Because the PCI­7200 is a Plug and Play device, there are no 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 Contents

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

X PCI-7200 Digital I/O & Counter Card

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

or

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

X 100-pin SCSI connector assembly

or

X LPCI-7200S Low profile Digital I/O & Cunter Card

X ADLINK CD

X 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 9

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. Ensure there is no
shipping and handling damage on the module before proceeding.

After opening the card module carton, remove 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 ensure 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 instructions on 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 recommended 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 Procedure

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 slots are shorter than the
ISA or EISA slots, and are usually white or ivory in
colour.

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

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 2-5 and 2.3.
