Introduction
Overview
The DIO-32.PCIe digital I/O interface provides 16 optically isolated inputs and 16 reed relay 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 close when energized.
The SeaI/O Classic software drivers and utilities can be obtained from the Sealevel web site. They make
installation and operation easy using Windows 7, Vista, and XP operating systems. The SeaI/O API
(Application Programmer Interface) 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. SeaI/O also includes sample
code and utilities to simplify software development.
The inputs on the 8004e are rated for 3-13V. The inputs on the 8004He are rated for 10-30V.
Features
•PCI Express X1 compliant
•16 optically isolated inputs
•Socketed dip resistor allows user configurable input range up to +30V
•16 Reed relay outputs (SPST)
•Highly reliable 10VA Reed relays
•Power (+5V and +12V) and ground provided on DB78 board connector
•Includes 72” cable with DB78 Male connector to DB37 Male and DB37 Female connectors (Item#
CA165)
•SeaI/O Classic software supports Windows 7, Vista, and XP operating systems
•Software support for Linux available

Cables
DB37 Male to DB37 Female Extension Cable (Item# CA112)
This cable provides a 6’ extension to the CA165. It has one
DB37 Male connector and one DB37 Female connector.
DB78 Male to DB78 Female Extension Cable (Item# CA233)
This cable provides a 6’ extension to the DB78 board
connector on the 8004e. It has one DB78 Male connector and
one DB78 Female connector.
DB78M to DB37 Female and DB37 Male, for 3093 (Item# CA378)
The CA378 is designed specifically for customers using the
3093 ISA digital I/O board that need to upgrade to the 8004e
PCIe board while preserving existing infrastructure wiring. The
CA378 connects to the 8004e and provides an identical pin out
to the 3093.
Terminal Blocks
DB37 Terminal Block (Item# TB02)
Break out serial and digital connectors to screw terminals for
easy field connection. The TB02 terminal block is designed
with both DB37 male and female connectors for interfacing
the inputs or outputs.

Hardware Installation
Do not install the PCI Express board until the software has been fully installed.
The DIO-32.PCIe does not need to be configured prior to installation.
Once you have installed the SeaI/O Classic software, install the board into an available PCI Express slot
and boot the computer. The Found New Hardware wizard will appear. The drivers that were installed
during the software installation process will automatically be used to configure the adapter.
The following instructions are applicable to the Windows XP operating system and may vary depending
on your version of Windows.
1. After the software installation is complete, install the ISO-16.PCIe into an available PCI Express
slot and boot the computer.
2. A ‘Found New Hardware’ alert will appear above the system tray.
3. When the ‘Found New Hardware’ alert informs you that your hardware is installed and ready to use,
you can proceed with verifying the installation to check functionality if necessary.

Verifying Installation
To confirm that the digital I/O card has been successfully installed and recognized by your operating
system, look in the Windows Device Manager.
To access Device Manager, follow the steps below:
1. Right click on ‘My Computer’ icon on your desktop or in the Start menu.
2. Click ‘Manage’ in the fly out menu to launch the ‘Computer Management’ console window.
3. In the left pane under ‘System Tools’, click ‘Device Manager’.
4. In right pane near the bottom, expand the ‘SeaI/O Device’ section by clicking the ‘+’ symbol. This
shows the parent device is installed correctly.
5. You should see the card assignment listed as ‘SeaI/O 8004e’ with the card number in parentheses.
The card number will increment for each additional SeaI/O device installed.
The DIO-32.PCIe is now ready for use.
