REL-16.PCI User Manual
Introduction
The REL-16.PCI provides 16 reed relay outputs. The outputs offer high quality, long
life, low current (10 Watt maximum), dry contact switch closures. Reed relays are
well suited for low current applications. The relays are normally open, and will close
when energized. The board is PCI bus specification 2.1 compliant.
The REL-16.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 REL-16.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/NT/2000/XP Installation
Do not install the Adapter in the machine 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/NT/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.

Linux Installation
Note: You MUST have "root" privileges to install the software and drivers.
1. Login as "root".
2. Mount the CDROM by typing:
3. Next change to the directory where you mounted the CDROM:
4. Copy seaio .tar.gz to your home directory by typing:
5. Change to your home directory by typing:
6. Unmount the drive and then Unzip and Untar the drivers and software by typing:
mount -t iso4860 /dev/hdc /cdrom
Note Your cdrom may not be /dev/hdc it could be /dev/hda, /dev/hdb, /dev/hdd,
or if you have a SCSI drive /dev/sda, /dev/sdb, /dev/sdc, etc. You may mount the
CDROM to any location, the /cdrom is just a common example.
Ex. cd /cdrom/software/SeaIO/Other/linux
Note: The syntax is case sensitive.
cp seaio .tar.gz ~
cd
umount /cdrom
tar -xvzf seaio .tar.gz
7. Change to the SeaIO directory by typing:
cd SeaIO
8. Now compile and prepare the drivers for use:
make install
9. With the system off and unplugged, install your SeaIO PCI card.
10. Plug system back in and boot Linux.
Login as "root".
11. Load the driver by typing:
SeaIO -load
The driver has enabled the card and is ready to use, and you now have the option
to run a test utility on it. Skip to section "Using the test software" if you wish to
do so at this time.
To set up Linux to automatically load the driver; refer to a Linux manual
concerning your specific distribution for help.

REL-16.PCI User Manual
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 REL-16.PCI is now ready for use.

REL-16.PCI User Manual
Programming the REL-16.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 REL-
16.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.
Digital I/O Interface
The REL-16.PCI provides two parallel reed relay output ports. The ports are
organized as ports A, B, C, and D. In order to maintain compatibility with the
existing ISA interface adapter (Sealevel Item# 3095), ports C and D (Base address+2
and 3) are the reed relay output port addresses.
Output Ports (Reed Relay)
Reed relays provide very high quality, long life, low current (10 Watt maximum),
dry contact switch closures. Reed relays are not suited for high current applications,
and can be destroyed by inductive load switching, where a spark occurs across the
contacts internally. The relays are normally open, and close when energized.

Reading the Outputs
The relay ports return the ones complement of the value that is currently being used
to drive the relays. When using the API the actual value is returned not the
complement of the value.
Writing the Outputs:
The output ports are the only ports that can be written. The relays on a standard
REL-16.PCI are normally open. To close a relay a one must be written to the
appropriate bit.
