Introduction The DIO-16.LPCI provides 8 optically isolated inputs and 8 reed relay outputs. The inputs 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.
Before You Get Started What’s Included The DIO-16.LPCI is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. DIO-16.LPCI Adapter • Item# 8012 ships with Low Profile PCI bracket • Item# 8012S ships with a standard PCI bracket Sealevel SeaI/O Software CD Optional Items Depending upon your application, you are likely to find one or more of the following items useful for interfacing the DIO-16.LPCI to real-world signals.
Software Installation Windows 98/ME/NT/2000/XP Installation 1. Start Windows. 2. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD 4. Select ‘Install Software’. 5. Select the Part Number for your adapter from the listing. 6. Select ‘Windows 98/ME/NT/2000/XP’.
Linux Installation Note: You MUST have "root" privileges to install the software and drivers. 1. Login as "root". 2. Mount the CDROM by typing: mount -t iso4860 /dev/hdc /cdrom Note Your cdrom may not be /dev/hdc it could be /dev/hda, /dev/hdb, /dev/hdd, or if you have a SCSI drive /dev/sda, /dev/sdb, /dev/sdc, etc. You may mount the CDROM to any location, the /cdrom is just a common example. 3. Next change to the directory where you mounted the CDROM: Ex.
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.
Programming the DIO-16.LPCI Sealevel’s SeaI/O software is provided to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. Included on the SeaI/O CD are driver functions for use in accessing the I/O as well as helpful samples and utilities. Programming for Windows The SeaI/O API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL).
Input Ports Port A is an 8 bit input port connected to optically isolated input sensors. Each sensor can be used to interface a voltage input and then sense whether the voltage is on or off. Each sensor is isolated (with respect to a common ground) from every other sensor, and is also isolated with respect to the host PC ground.

Reed relays are not suited for high current applications, and can be destroyed by inductive load switching, where a spark occurs across the contacts internally. The relays are normally open, and close when energized.
