Introduction
The DIO-32.104 is a PC/104 form factor adapter that provides 16 reed relays that can switch power, data,
or other electronic signals for control applications and 16 optically isolated inputs to allow monitoring of
off board switch closures, relays or for any other general purpose monitoring needs. The inputs (rated for
3-13V) 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 DIO-32.104 is designed to be used with a variety of Operating Systems including Windows, Linux, and
DOS. The SeaI/O API (Application Programmer Interface) included in the software available for the DIO-
32.104 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.

interfacing the DIO-32.104 to real-world signals. All items can be purchased from our website
(www.sealevel.com) or by calling 864-843-4343.
40-Pin IDC to DB-37 Male 6” Ribbon Cable (Part Number CA110)
For compatibility with other Sealevel digital I/O devices, the CA110 connects to the 40-pin
header connector on the DIO-32.104 and provides a DB-37 Male connector. The CA110 is
typically used for the relay output side of the DIO-32.104.

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.

Card Setup
Address Selection
The DIO-32.104 contains several jumper straps for each port that must be set for proper operation.
The DIO-32.104 occupies 4 consecutive I/O locations. The DIP-switch (S1) 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. To maintain
compatibility with other Sealevel Systems I/O adapters, the actual port addresses are found at
BaseAddress+2 (Relays K1-K8) and BaseAddress+3 (Relays K9-K16).
Address Binary Switch Settings

3A4-3A7 11 1010 01xx Off Off Off On Off On On Off
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.

Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while leaving it ‘Off’ or ‘Open’
corresponds to a ‘1’.

Physical Installation
Extreme care should be taken when installing the DIO-32.104 to avoid causing damage to the connectors.
After the adapter is installed, connect your I/O cables to the P1 (relays) and P2 (inputs) header connectors.
Please note these headers are keyed so that pin 1 of the cable matches pin 1 of the connector. Refer to
Card Setup for information on setting the address before inserting the DIO-32.104 onto the stack.
Do not install the Adapter in the machine until the software has been fully installed.
1. Turn off power. Disconnect the power cord.
2. Remove the case cover (if applicable).
3. Gently insert the DIO-32.104 connector noting proper key orientation of the expansion connector
on a PC/104 compatible card. The DIO-32.104 adapter is keyed per the current PC/104
Specification. This will aid in preventing the adapter from being inserted incorrectly.
4. Mounting hardware (nylon stand-offs and screws) is provided to ensure a good mechanical
connection. Retain any mounting hardware not used to allow for future expansion.
5. The cables provided are keyed and can be installed before or after the adapter is inserted in the
stack.
6. Replace the cover.
7. Connect the power cord and power up the machine.
The DIO-32.104 is now ready for use.
