PCI-469
24-Line, TTL-Level Digital I/O Board
for Desktop PCI Bus Computers
FEATURES
24 TTL/CMOS compatible digital I/O lines
Unidirectional, bidirectional, and strobed I/O
Interrupt interface circuitry (A through D)
Direct interface to wide range of accessory products
Brings out 12V and 5V power from bus with fuses
Lines and ports configurable as inputs or outputs
The PCI-469 provides 24 TTL/CMOS compatible digital input/
output lines for a wide variety of digital I/O applications. The
board also provides access to the PCI bus interrupt inputs and
also includes connections to the computer's power supplies
with the addition of a 5 VDC supply and field replaceable
fuses.
On the PCI-469, an industry standard 82C55 programmable
peripheral interface (PPI) provides 24 digital I/O lines. The
PCI-469 supports all 82C55 features including operating
modes 0, 1, and 2.
The 24 digital I/O lines of the PCI-469 form three separate 8
bit ports. These ports can be set independently under
software control as inputs or outputs. In addition to operating
as a standard 8 bit I/O data port, the third port can be
subdivided into two, four bit data ports as input or output. All
ports are configured as inputs on power-up or reset.

PRODUCT DATA
A tri-state driver with separate enable (interrupt enable -
active low) handles interrupts. This driver can be connected
to any of the interrupt levels `A' through `D' available on the
PCI bus via a 4 position DIP switch.
The PCI-469 includes a Windows 95/98 and Windows NT/2K
control panel. Also available are sample programs, source
code, and an ActiveX control for all popular programming
languages and packages.

I/O Connector
The I/O connector for the PCI-469 is a standard DB-375
37-pin female type and is accessible at the rear of the
computer chassis.

Software
Windows 95/98/NT/2K have become the platforms of choice
for many data acquisition, test, measurement, and control
applications. These feature rich, 32-bit operating systems
exploit huge amounts of memory, secure multi-threading, and
hardware plug-n-play (PnP) to provide high performing, user
friendly working environments.
PCI-469WIN
Each PCI-469 includes installation software for hardware
detection and initialization under Windows 95/98 and Windows
NT. The control panel provides an easy to use, point and click
graphical user interface (GUI) allowing access to 82C55, port
direction configuration, and reading and writing data.
PCI-469WINS
The PCI-469WINS includes all the features of the
PCI-469WIN software plus the complete source code to the GUI
application (Microsoft Visual Basic) and DLLs (Visual C++), and
allows you to communicate with the PCI-469 from the familiar
environment of your favorite high level language - C/C++, Visual
Basic, Delphi, LabVIEW
, etc. Its standard Windows
programming hierarchy facilitates custom software development
of the PCI-469 into other applications. The source code also
contains some simple example programs in Visual Basic, Visual
C++, and National Instruments' LabVIEW.
LabVIEW Support
Included with the PCI-469WINS, is a tutorial on how to convert
the PCI-469 ActiveX control to a LabView VI (Virtual
Instrument) that allows complete hardware control under
LabVIEW. This software also allows for the control of multiple
PCI-469s in one system and includes complete functional VI
sample programs.
