Introduction The DIO-104.OPTO is a PC/104 form factor adapter that provides 16 optically isolated inputs (rated for 3- 13V) to allow monitoring of off board switch closures, relays or for any other general purpose monitoring needs. The DIO-104.OPTO is designed to be used with a variety of Operating Systems including Windows and DOS.
Before You Get Started Wat’s Included The DIO-104.REL is shipped with the following items. If any of these items are missing or damaged, please contact Sealevel for replacement. • DIO-104.OPTO 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.

DIO-104.OPTO and provides a DB-37 Female connector. DB-37 Male to DB-37 Female 6’ Cable - (Part Number CA112) This cable extends the DB-37 connector on the DIO-104.OPTO 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.
Card Setup Address Selection The DIO-104.OPTO 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. Even though four I/O addresses are decoded, only the first two are actually used, the other two ports are to maintain compatibility with existing Sealevel Systems adapters.
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-104.OPTO to avoid causing damage to the connectors. After the adapter is installed, connect your I/O cable to P2. 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-104.OPTO onto the stack.
Digital I/O Interface The DIO-104.OPTO 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 decoded but not used.

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.
