CPCI-560
24-Line, TTL-Level Digital I/O Board
for the CompactPCI
Bus
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 CPCI-560 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 CPCI-560, an industry standard 82C55 programmable
peripheral interface (PPI) provides 24 digital I/O lines. The
CPCI-560 supports all 82C55 features including operating
modes 0, 1, and 2.
The 24 digital I/O lines of the CPCI-560 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.

PRELIMINARY 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 CPCI-560 includes a Windows 95/98 and Windows NT
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 CPCI-560 is a standard 37-pin
female type and is accessible at the front of the CPCI chassis.

Software
Windows 95/98/NT 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.
CPCI-560WIN
Each CPCI-560 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.
CPCI-560WINS
The CPCI-560WINS includes all the features of the
CPCI-560WIN software plus the complete source code to the
GUI application (Microsoft Visual Basic) and DLLs (Visual C++),
and allows you to communicate with the CPCI-560 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 CPCI-560 into other applications. The source code also
contains some simple example programs in Visual Basic, Visual
C++, Quick C, and National Instruments' LabVIEW.
LabVIEW Support
Included with the CPCI-560WINS, is a tutorial on how to
convert the CPCI-560 ActiveX control to a LabView VI (Virtual
Instrument) that allows complete hardware control under
LabVIEW. This software also allows for the control of multiple
CPCI-560s in one system and includes complete functional VI
sample programs.
