Depending upon your application, you are likely to find one or more of the following items
useful for interfacing the DIO-16.LPCI to real-world signals.
All items can be purchased from our website (http://www.sealevel.com) or by calling +1 864-
843-4343.
DB44 Male to DB44 Female, 72” Extension Cable (Item# CA185)
The CA185 is a standard DB44M to DB44F extension
cable. Extend a DB44 cable or locate a piece of hardware
where it is needed with this six foot (72”) cable. The
connectors are pinned one-to-one so the cable is

The DIO-16.LPCI provides 8 optically isolated inputs and 8 reed relay SPST (single pole-single
throw) outputs. The inputs protect the PC and other sensitive equipment from spikes and
ground loop current that can be generated in industrial environments, while the outputs
provide 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 meets the requirements for the MD1 "Low Profile" specification as defined by the
PCISIG in the PCI 2.2 Specifications Low Profile Addendum. The DIO-16.LPCI also features
Universal Bus (3.3 and 5.0V) operation.
The DIO-16.LPCI is designed to be used with a variety of Operating Systems including Windows,
Linux and DOS. The SeaI/O API (Application Programming Interface) included on the CD shipped
with the DIO-16.LPCI provides a variety of useful high-level function calls implemented as a
Windows dynamic link library (.DLL) and as a Linux static library (.a). In addition to the API,
SeaI/O includes a device driver, sample code, and utilities to simplify software development.
Eight optically isolated inputs optimized for +5V
Eight Reed relay outputs (SPST)
Highly reliable 10VA Reed relays
MD1 Low Profile and Universal Bus (3.3V and 5V) compatible
Power (+5V and +12V) and ground provided on connector
SeaI/O Classic software supports Windows and Linux Operating Systems

Most Sealevel Linux software is distributed as source code. To use the software, it must
be compiled. Refer to the README file in each package for system prerequisites.
You must have administrative privileges to install the software. It is not necessary to
have administrative privileges to build or use the software.
All command syntax is case sensitive.
1. Insert the Sealevel media into your PC.
2. If your desktop environment does not auto-mount the media, you will need to do
so manually using the mount command. You may need administrative privileges
for the mount command to succeed.
3. Next change to the Sealevel media directory. For example, if the mount point of
your optical drive is /cdrom:
$ cd /cdrom/Software/SeaIO/Linux
4. Copy [package name].tar.gz to your home directory by typing:
$ cp SeaIO_X.Y.Z.tar.gz ~
5. Change to your home directory by typing:
$ cd
6. Extract the software from the compressed archive by using:
$ tar -zxvf SeaIO_X.Y.Z.tar.gz
7. Change to the package directory by typing:
$ cd seaio
8. Compile the software from source by typing:
$ make
9. Elevate permission level by changing to root:
$ su
Or use the ‘super user do’ command:
$ sudo –s
10. Install the drivers by typing:
$ make install

11. If the package contains drivers, refer to the documentation for your package to
find the command that will load your drivers. For example, the SeaI/O package
uses:
$ seaioload
At this point, the driver has enabled the hardware and it is ready to use. You now have the
option to run a test utility on it. Test utilities were compiled in Step 8, and they are located in
the package‟s folder named seaio/utilities/ and installed globally in Step 10 to: /usr/bin.

Programming the DIO-16.LPCI
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.
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 DIO-16.LPCI. If you
are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised.
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.
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.
In systems where the user‟s program has direct access to the hardware (DOS) the tables that
follow give the mapping and functions that the DIO-16.LPCI provides. The DIO-16.LPCI provides
two parallel input/output (I/O) ports. The ports are organized as ports A and C. Port A is an
input port interfaced to optically-isolated inputs, while port C is the reed relay output port.

The inputs are active Low. If no voltage is applied across one of the differential inputs it
returns a one on that bit. If an AC or DC voltage is applied it returns a zero on that bit.
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.
The output ports are the only ports that can be written. The relays on a standard DIO-16.LPCI
are normally open. To close a relay a one must be written to the appropriate bit.
When enabled, interrupts are generated on Port A bit D0.

Port A is an 8 bit input port connected to optically isolated input sensors. Each sensor can be
used to interface a voltage input and then sense whether the voltage is on or off. Each sensor is
isolated (with respect to a common ground) from every other sensor, and is also isolated with
respect to the host PC ground. This means that signals such as low-level AC line voltage, motor
servo voltage, and control relay signals can be „sensed‟, or read by the PC, without the risk of
damage due to ground loops or ground faults.
Each sensor input pair has a current limiting resistor that is used to limit the input current to
the opto-isolator. The opto-isolator has two „back-to-back‟ diodes internally. This allows AC or
DC signals to be sensed, regardless of polarity. When the applied voltage is high enough to
cause the LED in the opto-isolator to turn-on, the output of the opto-isolator goes low (0 volts)
and the signal is read as a low logic level (binary 0) by the PC. When the input signal is too low
to turn on the opto-isolator, the output goes high and the port bit is read by the PC as a high
logic level (binary 1).
The input impedance of each isolated input is approximately 560 ohms (factory default). The
opto-isolator requires approximately 3mA to turn on. The maximum input current is 20mA.
The input circuits are not intended for monitoring 120-volt AC circuits. In addition to
being too high a voltage for the circuits, it is dangerous to have that high a voltage on
the card.
