PIO-24.LPCI User Manual
Introduction
The PIO-24.LPCI, part number 8018, digital I/O interface provides 24 channels of
buffered drive digital I/O emulating 8255 mode zero. The PIO-24.LPCI 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-24.LPCI’s 24 digital I/O channels are accessed via two 26-pin header
connectors that are brought out to a single 50-pin IDC connector with the included
CA315 ribbon cable. The headers provide 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-24.LPCI 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-24.LPCI 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.
The RoHS compliant version of the PIO-24.LPCI, part number 8018-RoHS, meets
the RoHS (2002/95/EC) and WEEE (2002/96/EC) directives.

Before You Get Started
What’s Included
The PIO-24.LPCI is shipped with the following items. If any of these items is
missing or damaged please contact Sealevel for replacement.
PIO-24.LPCI Adapter
IDC 50 to (2) IDC 26 Pin 40" Ribbon Cable (Part Number CA315)
Sealevel SeaI/O Software CD
Optional Items
Depending upon your application, you are likely to find one or more of the
following items useful for interfacing the PIO-24.LPCI to real-world signals. All
items can be purchased from our website (http://www.sealevel.com) or by calling
(864) 843-4343.
For TTL applications:
IDC 50 to (2) IDC 26 Pin 40" Ribbon Cable (Part Number CA315)
− Connects to the two 26-pin header connectors on the 8018 and brings
them out to a single 50-pin IDC connector, which is compatible with
industry-standard relay racks.
Terminal Block - (Part Number TB07)
− The TB07 allows you to break out 24 digital signals, +5 volts, and
ground to screw terminals for easy field connection of switches,
discrete solid state relays, sensors, etc.
Simulation/debug module (Part Number TA01)
− Module allows monitoring status of output pins and controlling state
of input pins. An LED corresponding to each port bit illuminates to
indicate state. Eight position DIP-switches are used to generate input
status changes.

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.
