PIO-96.PCI User Manual
Introduction
The PIO-96.PCI part number 8009 digital I/O interface provides 96 channels of
buffered drive digital I/O emulating 8255 mode zero. The PIO-96.PCI can be
utilized for a variety of control and automation applications including control and
monitoring of TTL devices (e.g. LEDs, small solenoids, small relays) and
interfacing to solid-state relay racks (SSRs) for high-power AC or DC loads.
The PIO-96.PCI’s 96 digital I/O channels are accessed via four 50-pin header
connectors with industry-standard pin out. Each header provides 24 bits of digital
I/O divided into three eight-bit groups. Each eight-bit group may be individually
configured via software command as input or output to best match your particular
application requirements.
The PIO-96.PCI is designed to be used with a variety of Operating Systems
including Windows 98/NT/ME/2000/XP, Linux and DOS. The SeaI/O API
(Application Programmer Interface) included on CD with the PIO-96.PCI provides a
variety of useful high-level function calls implemented as a Windows dynamic link
library (DLL) and as a Linux kernel module and library. In addition to the API,
SeaI/O includes sample code and utilities to simplify software development.

Software Installation
Windows 98/ME/2000/XP Installation
1. Start Windows.
2. Insert the Sealevel Systems CD in to your CD drive.
3. If ‘Auto-Start’ is enabled for this drive the software will automatically
launch. Otherwise, point your browser to the ‘Index.htm’ on the root
directory of the CD
4. Select ‘Install Software’.
5. Select the Part Number for your adapter from the listing.
6. Select ‘Windows 98/ME/2000/XP’. The setup file will automatically detect
the operating environment and install the proper components. Next
(depending on your browser) select the ‘Run this program from its current
location’ or ‘Open’ option. Follow the information presented on the screens
that follow.
7. A screen may appear with the declaration: “The publisher cannot be
determined due to the problems below: Authenticode signature not found.”
Please select the ‘Yes’ button and proceed with the installation. This
declaration simply means that the Operating System is not aware of the
driver being loaded. It will not cause any harm to your system.
8. During setup the user may specify installation directories and other
preferred configurations. This program also adds entries to the system
registry that are necessary for specifying the operating parameters for each
driver. An uninstall option is also included to remove all registry/INI file
entries from the system.
Windows NT Card Installation: After accomplishing the above steps, bring up the
Control Panel and double-click on the SeaIO Devices icon. To install a new card,
click "Add Port". Repeat this procedure for as many SeaIO cards as you wish to
install.

Digital I/O Interface
The PIO-96.PCI’s 96 digital I/O channels are accessed via four industry-standard
50-pin header connectors. Each header provides 24 bits of digital I/O divided into
three eight-bit ports. Each port may be individually configured via software
command as input or output.
50-pin Header Connectors
You will need to install the bracket assembly and cables to the PIO-96.PCI prior to
installing it in the PC. The PIO-96.PCI’s bracket features a unique cable clamp that
provides a solid strain relief to prevent inadvertent cable removal.
Each of the four 50-pin connectors has the following pin out which is compatible
with a wide variety of solid state relay racks:

PIO-96.PCI User Manual
Programming the PIO-96.PCI
Sealevel’s SeaI/O software is provided to assist in the development of reliable
applications for the Sealevel Systems family of digital I/O adapters. Included on the
SeaI/O CD are driver functions for use in accessing the I/O as well as helpful
samples and utilities.
Programming for Windows
The SeaI/O API (Application Programmer Interface) provides a variety of useful
high-level function calls implemented in a Windows dynamic link library (DLL).
The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under
“Application Programmers Interface”. This help file also includes detailed
information dealing with installation / removal of the software and information
about latency, logic states, and device configuration.
For C language programmers we recommend using the API to access the PIO-
96.PCI. If you are programming in Visual Basic, using the ActiveX control
included with SeaI/O is advised.
Samples and Utilities
A variety of sample programs and utilities (both executable and source code) are
included with SeaI/O. Further documentation on these samples can be found by
selecting “Start/Programs/SeaIO/Sample Application Description”. Information
about where the files are physically stored on your disk is also included in this same
file.
Programming for Linux
SeaI/O for Linux consists of two major parts: a kernel module and a library. The
kernel module is a simple IO pass-through device, allowing the library to handle the
more sophisticated functions provided to SeaI/O users. It is provided in a ‘tarball’
format and can easily be compiled and included in the kernel build.
Direct Hardware Control
In systems where the users program has direct access to the hardware (DOS) the
tables that follow give the mapping and functions that the PIO-96.PCI provides.
Reading the Inputs
The inputs are active true. If an input is driven high (2V to 5.25 V) it will read as a
logical one, if driven low (0V to 0.8V) it will read as a logical zero. If an input is not
driven it will read as a one due to the 10K ohm pull up resistors on each port.
Reading the Outputs
The value that is currently being used to drive the outputs will be returned.

PIO-96.PCI User Manual
Presetting an Output Port
Each port has an output register associated with it. This register may be written and
retains its value whether the port is configured as an input or an output. To preset the
value of an output port the program should write to the port when it is configured as
an input then configure it as an output.
Writing the Outputs
The outputs are active true. Writing a one (1) corresponds to 5V while writing a zero
(0) corresponds to 0V, at the output.
