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: 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 operations 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, digital I/O data can utilize
simple handshaking data transfer.

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.

8 •Installation
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.
