Page 3: Introduction
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. -
Page 4: Before You Get Started
Before You Get Started What’s Included The DIO-16 is shipped with the following items. If any of these items are missing or damaged, please contact Sealevel for replacement. • DIO-16 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. - Page 5 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.

Page 6: 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. - Page 7 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. IRQ Header E2 © Sealevel Systems, Inc. 3096H Manual | SL9026H 7/2021...

Page 8: Software 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. © Sealevel Systems, Inc. 3096H Manual | SL9026H 7/2021... - Page 9 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. © Sealevel Systems, Inc. 3096H Manual | SL9026H 7/2021...

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.) Replace the cover. Connect the power cord The DIO-16 is now ready for use. © Sealevel Systems, Inc. 3096H Manual | SL9026H 7/2021... -
Page 11: Programming The Dio-16
/ removal of the software and information about latency, logic states, and device configuration. For C language programmers we recommend using the API to access the DIO-16. If you are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised. - Page 12 Digital I/O Interface The DIO-16 provides two parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Port A is an input port interfaced to optically isolated inputs, while port C is the reed relay output port. Ports B and C are unused.
- Page 13 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 relays on a standard DIO-16 are normally open. To close a relay a one must be written to the appropriate bit.
