Introduction
The PIO-32.PCI part number 8010 digital I/O interface provides 32 channels of buffered drive digital I/O.
The PIO-32.PCI can be utilized for a variety of control and automation applications including control and
monitoring of TTL devices (e.g. LEDs, small solenoids, and small relays) and interfacing to solid-state relay
racks (SSRs) for high-power AC or DC loads.
The PIO-32.PCI’s 32 digital I/O channels are accessed via a 50-pin header connector with industry-standard
pin out. The header provides 32 bits of digital I/O divided into four 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-32.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 in the
software 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 Installation
Do not install the adapter in the machine until the software has been fully installed.
Only users running Windows 7 or newer should utilize these instructions for accessing and installing
the appropriate driver via Sealevel’s website. If you are utilizing an operating system prior to
Windows 7, please contact Sealevel by calling 864.843.4343 or emailing [email protected] to
receive access to the legacy driver download and installation instructions.
1. Select the download for the SeaIO Classic for Windows (Software: SeaIO Classic V5 - Windows
- Sealevel.) 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.
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 available to remove SeaIO
files and registry/INI file entries from the system.
2. 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.
3. 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 software installation is complete.
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.
Linux Software: You may download the SeaIO Classic for Linux Windows for the 8010. If you need
additional information with this installation, please contact Sealevel’s Technical Support:
[email protected].

Physical Installation
The adapter can be installed in any 5V PCI expansion slot.
Do not install the adapter in the machine until the software has been fully installed.
1. Turn off PC power. Disconnect the power cord.
2. Remove the PC case cover.
3. Locate an available 5V PCI slot and remove the blank metal slot cover.
4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated
properly.
5. After the adapter has been installed, the cables should be routed thru the opening in
the bracket. This bracket also features a strain relief function that should be used to
prevent un-expected cable removal.
6. Replace the screw you removed for the blank and use it to secure the adapter into the
slot. (This is required to ensure FCC Part 15 compliance.)
7. Replace the cover.
8. Connect the power cord.
The PIO-32.PCI is now ready for use.

Digital I/O Interface
The PIO-32.PCI’s 32 digital I/O channels are accessed via an industry-standard 50-pin header connector.
The header provides 32 bits of digital I/O divided into four eight-bit ports. Each port may be individually
configured via software command as input or output.
Relay racks with less than 32 channels expect all even pins to be commons. When using relay
racks with less than 32 channels, set Port D as an input to avoid shorting the outputs to ground
through the relay rack.
50-pin Header Connector
The PIO-32.PCI’s bracket features a unique cable clamp that provides a solid strain relief to prevent
inadvertent cable removal. You will need to install the bracket assembly and cable to the PIO-32.PCI prior
to installing it in the PC. The 50-pin connector has the following pin out which is compatible with a wide
variety of solid state relay racks.

Programming the PIO-32.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 in Sealevel’s software and drivers 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-32.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 in the software
for the SeaI/O. Further documentation on these samples can be found by selecting
“Start/Programs/SeaIO/Sample Application Description.” If you have any problems locating these files,
please contact Sealevel’s Technical Support at 864-843-4343 or email [e-mail].
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-32.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.
