Introduction

The DIO-16 provides 8 optically isolated inputs and 8 reed relay outputs. The inputs (rated for 10-30V)

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 is PCI bus specification 2.1 compliant.

The DIO-16 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 in the

software available for the DIO-16 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.

Advisory Conventions

Warning

The highest level of importance used to stress a condition where damage could result to the

product, or the user could suffer serious injury.

Important

The middle level of importance used to highlight information that might not seem obvious or a

situation that could cause the product to fail.

Note

The lowest level of importance used to provide background information, additional tips, or other

non-critical facts that will not affect the use of the product.

Optional Items

Depending upon your application, you are likely to find one or more of the following items useful for

interfacing the DIO-16 to real-world signals. All items can be purchased from our website

(www.sealevel.com) or by calling (864) 843-4343.

DB-37 Male to DB-37 Female 6’ Cable - (Part Number CA112)

This cable extends the DB-37 connector on the REL-16.PCI to six feet and is pinned one-to-one.

DB-37 Male/Female Terminal Block (Part Number TB02-KT)

Break out serial and digital connectors to 37 screw terminals for easy field connection. The TB02

terminal block is designed with both DB-37 male and female connectors, therefore; it can be

used with any DB-37 board regardless of the board's port gender.

Cable and Terminal Block Kit (Part Number KT101)

For convenient and easier ordering, the KT101 includes the TB02-KT terminal block and CA112

cable in a single kit.

Card Setup

The DIO-16 contains several jumper straps for each port that must be set for proper operation.

Address Selection

The DIO-16 occupies 4 consecutive I/O locations. The DIP-switch (SW1) is used to set the base address for

these locations. Be careful when selecting the base address as some selections conflict with existing PC

ports. The following table shows several examples that usually do not cause a conflict.

Address Selection Table

The following illustration shows the correlation between the DIP-switch setting and the address bits used

to determine the base address. In the example below, address 300 is selected as the base address. Address

300 in binary is XX 11 0000 00XX where X = a non-selectable address bit and address bit A9 is always a 1.

DIP-Switch Illustration

Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while leaving it ‘Off’ or ‘Open’

corresponds to a ‘1’.

IRQ Header E2

Interrupts can be generated by Port A, bit 0 going low if enabled at jumper location (E2). Interrupt request

signals 2/9 through 7 (IRQ 2/9 - 7) can be selected by placing the jumper in the appropriate position. Other

inputs can be ‘wire OR ed.’ to also generate interrupts if desired. Please consult the factory for more

information.

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. Begin by locating, selecting, and installing the correct software (SeaIO Classic for Windows) from

the Sealevel software driver database.

2. Select the Part Number (3096H) for your adapter from the listing.

3. Select ‘Download Now” for the SeaIO Classic for Windows. 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.

4. 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.

5. 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

You MUST have “root” privileges to install the software and drivers.

1. Begin by locating, selecting, and installing the correct software (SeaIO Classic for Linux) from the

Sealevel software driver database.

2. Select the Part Number (3096H) for your adapter from the listing.

3. Select “Download Now” for the SeaIO Classic for Linux.’ 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.

4. Now compile and prepare the drivers for use: make install

5. With the system off and unplugged, install your SeaIO PCI card.

6. Plug system back in and boot Linux. Login as "root".

7. Load the driver by typing: SeaIO -load

8. The driver has enabled the card and is ready to use.

To set up Linux to automatically load the driver; refer to a Linux manual concerning your specific

distribution for help.

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 DIO-16 is now ready for use.
