Introduction
The SeaLINK PIO-48, part number 8203, 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-48’s 48 digital I/O channels are accessed via two 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-48 is designed to be used under Windows 98/ME/2000/XP. The SeaI/O API (Application
Programmer Interface) available on Sealevel’s website 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-48’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 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]om to receive access to the legacy driver download and installation
instructions.
1. Begin by locating, selecting, and installing the correct software from the Sealevel software
driver database.
2. Select the Part Number (#8203) for your adapter from the listing.
3. Select ‘Download Now for SeaIO Classic for Windows’. The setup file will automatically
detect the operating environment and install the proper components. Next (depending on

Digital I/O Interface
The SeaLINK PIO-48’s 48 digital I/O channels are accessed via two 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 Connector
You will need to open the SeaLINK PIO-48’s enclosure to access the two header connectors P2 and P3 (see
Appendix C 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 two 50-pin connectors has the following pin out which is compatible with a wide variety of solid
state relay racks:

Programming the SeaLINK PIO-48
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 the SeaI/O software 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 SeaLINK PIO-48. 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.

Appendix A –Troubleshooting
The adapter should provide years of trouble-free service. However, in the event that device appears to not
be functioning incorrectly, the following tips can eliminate most common problems without the need to call
Technical Support.
1. Read this manual thoroughly before attempting to install the adapter in your system.
2. Use Device Manager under Windows to verify proper installation.
3. Use the SeaI/O control panel applet for card identification and configuration.
4. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports,
controller cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if
any) should be identified.
5. Configure your Sealevel Systems adapter so that there is no conflict with currently installed
adapters. No two adapters can occupy the same I/O address.
6. Make sure the Sealevel Systems adapter is using a unique IRQ The IRQ is typically selected via an
on-board header block. Refer to the section on Card Setup for help in choosing an I/O address and
IRQ.
7. Make sure the Sealevel Systems adapter is securely installed in a motherboard slot.
8. If you are utilizing an operating system prior to Windows 7, please contact Sealevel‘s Technical
support as directed below to receive more information regarding the utility software which will
determine if your product is functioning properly.
9. Only users running Windows 7 or newer should utilize the diagnostic tool ‘WinSSD’ installed in the
SeaCOM folder on the Start Menu during the setup process. First find the ports using the Device
Manager, then use ‘WinSSD’ to verify that the ports are functional.
10. Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will
help eliminate any software issues and identify any hardware conflicts.
