Introduction
SeaLINK PIO-96
The SeaLINK PIO-96, part number 8205, provides an easy method for interfacing
common digital I/O circuitry via any computer’s USB port. Typical applications
include control/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 SeaLINK PIO-96’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 SeaLINK PIO-96 is designed to be used under Windows 98/ME/2000/XP. The
SeaI/O API (Application Programmer Interface) included on CD with the SeaLINK
PIO-96 provides a variety of useful high-level function calls implemented in a
Windows dynamic link library (DLL). This API gives access to the SeaLINK PIO-
96’s I/O from Windows-based platforms such as Visual C++. In addition to the
API, SeaI/O includes an ActiveX control along with sample code and utilities to
simplify software development.

Software Installation
Windows 98/ME/2000/XP Installation
Important: Do not connect the SeaLINK PIO-96 adapter to the host USB
device until the software has been fully installed.
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 Note: Windows NT is not USB aware and thus cannot support the
SeaLINK PIO-96.

Physical Installation
Once you have completed installing the software driver simply connect the
SeaLINK PIO-96 to your USB port with the supplied cable. Next connect the DC
power input from the AC adapter. The software drivers installed during setup will
automatically recognize and configure the device. You should see one or more “New
Hardware Found” windows, indicating the actual device being created. Next, view
your system’s Device Manager. You should have a new ‘SeaIO 8205’ in the SeaI/O
Device heading indicating the installation was successful.
The SeaLINK PIO-96 is now ready for use.

Digital I/O Interface
The SeaLINK PIO-96’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 open the SeaLINK PIO-96’s enclosure to access the four header
connectors P2, P3, P4, and P5 (see Appendix B for connector locations). To open,
remove the four screws found on the bottom panel of the unit. Once cables are
connected to the headers reassemble the enclosure with the cables exiting the
opening on the back panel of the unit.
Each of the four 50-pin connectors has the following pin out which is compatible
with a wide variety of solid state relay racks:

Electrical Characteristics
The SeaLINK PIO-96 uses 74ABT245 octal bi-directional transceivers to provide
TTL input/output capabilities. Each bit is pulled to +5V through a 10K ohm pull-up
resistor to insure each bit is at a known state when not driven.
