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...
Before You Get Started What’s Included The DIO-32.104 is shipped with the following items. If any of these items are missing or damaged, please contact Sealevel for replacement. DIO-32.104 Adapter • 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.

40-Pin IDC to DB-37 Female 8” Ribbon Cable (Part Number CA211) The CA211 connects to the 40-pin header connector on the DIO-32.104 and provides a DB- 37 Female connector. The CA211 is typically used for the isolated input side of the DIO- 32.104.
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.
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 support@sealevel.com...

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.
Digital I/O Interface The DIO-32.104 provides four parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Ports A and B are input ports interfaced to optically-isolated inputs, while ports C and D are reed relay output ports.

Increasing the input resistor accordingly can increase the maximum input voltage. Because socketed DIP resistors are utilized, they can easily be replaced with a different value. Sealevel, if necessary can do this. 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.

The relay ports return the ones complement of the value that is currently being used to drive the relays. Writing the Outputs The output ports are the only ports that can be written. The relays on a standard DIO-32.104 are normally open. To close a relay a one must be written to the appropriate bit.
If these steps do not solve your problem, please call Sealevel Systems’ Technical Support, (864) 843-4343. Our technical support is free and available from 8:00 A.M.- 5:00 P.M. Eastern Time Monday through Friday.
If possible, please have the adapter installed in a computer ready to run diagnostics. 3. Sealevel Systems provides an FAQ section on its web site. Please refer to this to answer many common questions. This section can be found at http://www.sealevel.com/faq.htm...
