Optional Items
Depending upon your application, you are likely to find one or more of the following items useful for
interfacing the DIO-16.LPCIe to real-world signals. All items can be purchased from our website
(www.sealevel.com) or by calling [phone].
Cables
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
compatible with any device or cable with DB44
connectors. The cable is fully shielded against
interference and the connectors are molded to provide
strain relief. Dual metal thumbscrews secure the cable
connections and prevent accidental disconnection.
DB44 Male to BD37 Male, 72” Cable (Item# CA206)
DB44 Male to DB37 Male Cable, 72 in Length - for 8012.
The CA206 is useful for interfacing the DB44 connector
on the 8012e to the DB37 connector on the TB02 terminal
block.

Terminal Blocks
Terminal Block – DB37 Male and DB37 Female to 27 Screw Terminals (Item# TB02)
(Cable & Terminal Block Kit)
The TB02 terminal block can be used to break out serial
and digital DB37 connectors to screw terminals for easy
field wiring. The terminal block was designed with both
DB37 male and female connectors, therefore; it can be
used with any DB37 board regardless of the board's port
gender.
Terminal Block Kit – DB37 Male and DB37 Female to 27 Screw Terminals (Item# TB02-KT)
The TB02-KT terminal block can be used to break out
serial and digital DB37 connectors to screw terminals for
easy field wiring. The terminal block was designed with
both DB37 male and female connectors, therefore; it can
be used with any DB37 board regardless of the board's
port gender. The TB02-KT ships with a RoHS compliant
TB02 terminal block, a 6” piece of slotted Snap Track, and
two DIN-rail mounting clips.
Terminal Block Kit – TB02 + CA206 Cable (Item# KT111)
Terminal Block KT111 simplifies field wiring
requirements by creating a direct connection between a
TB02 terminal block and the 8012 board. The KT111
includes the TB02 terminal block, CA206 cable, ST101
Snap Track and STDIN mounting clips.
Reference Book
The Digital I/O Handbook – A Practical Guide to Industrial Input and Output Applications
(Item# REF101)
Renowned technical author Jon Titus and president and
CEO of Sealevel Systems, Tom O'Hanlan, clearly explain
real-world digital input/output implementation from both
a hardware and software perspective. Whether you are a
practicing engineer or a student, The Digital I/O
Handbook will provide helpful insight you will use again
and again.

Introduction
The DIO-16.LPCIe 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 a low profile PCI Express add-in card as defined by the PCI-SIG in the
PCI Express Card Electromechanical Specification Revision 1.1.
The DIO-16.LPCIe is designed to be used with Windows Operating Systems. The SeaI/O API (Application
Programming Interface) included in Sealevel’s software provides a variety of useful high-level function calls
implemented as a Windows dynamic link library (.DLL). In addition to the API, SeaI/O includes a device
driver, sample code, and utilities to simplify software development.
Features
•PCI Express x1 compliant
•Eight optically isolated inputs
•Eight Reed relay outputs (SPST)
•Low Profile compliant
•Power (+5V and +12V) and ground provided on connector

Software Installation
Windows Installation
Do not connect the hardware 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] to receive access to the proper driver download and installation
instructions.
1. Begin by locating, selecting, and installing the correct software from the Sealevel software
driver database.
2. Type in or select the part number (#8012e) for the adapter from the listing.
3. Select “Download Now” for SeaI/O for Windows.
4. The setup files will automatically detect the operating environment and install the proper
components. Follow the information presented on the screens that follow.
5. A screen may appear with text similar to: “The publisher cannot be determined due to the
problems below: Authenticode signature not found.” Please click 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.
6. 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.
7. The software is now installed, and you can proceed with the hardware installation.
To install Sealevel software, you must log in as an administrator or have administrator privileges in
Windows. All Sealevel Systems software drivers have been fully tested by Sealevel. Clicking “OK”
button to continue.

Physical Installation
Do not install the PCI express board until the software has been successfully installed.
The Sealevel DIO-16-LPCIe can be installed in any PCIe expansion slot (x1/x4/x16).
PCI Express x1
Do not install the adapter in the machine until the product software has been fully installed.
To prevent damage from improper handling, please reference Appendix B – ESD Handling
Instructions.
1. Turn off PC power. Disconnect the power cord.
2. Remove the PC case cover.
3. Locate an available PCIe slot and remove the blank metal slot cover.
4. Gently insert the PCIe adapter into the slot. Make sure that the adapter is seated properly.
5. Replace the screw you removed for the blank and use it to secure the adapter bracket into the
slot. This is required to ensure FCC Part 15 compliance.
6. Replace the cover.
7. Connect the power cord.

Programming the DIO-16.LPCIe
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 DIO-16.LPCIe. 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.
Register Layout
Reference the following sections for more information about the meaning and use of the registers available.
Address Mode Mode D7 D6 D5 D4 D3 D2 D1 D0
Base+0 Input Port A RD PAD7 PAD6 PAD5 PAD4 PAD3 PAD2 PAD1 PAD0
Base+2 Output Port C RD/WR PCD7 PCD6 PCD5 PCD4 PCD3 PCD2 PCD1 PCD0
Reading the Inputs
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.
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.
