Introduction The ISO-16.PCI 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 ISO-16.PCI is PCI 2.1 bus compliant. The ISO-16.PCI is designed to be used with a variety of Operating Systems including Windows 98/NT/ME/2000/XP, Linux and DOS. The SeaI/O API (Application Programmer Interface) included on CD with the ISO-16.
Before You Get Started What’s Included The ISO-16.PCI is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. ISO-16.PCI Adapter 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 ISO-16.PCI to real-world signals. All items can be purchased from our website (http://www.sealevel.com) or by calling (864) 843-4343.
Software Installation Windows 98/ME/NT/2000/XP Installation Do not install the Adapter in the machine until the software has been fully installed. 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.
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. Replace the screw you removed for the blank and use it to secure the adapter into the slot.
Programming the ISO-16.PCI 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 Ports A and B are 8 bit input ports 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 also isolated with respect to the host PC ground.

Reading the Inputs The inputs are active Low. If no voltage is applied across one of the differential inputs it returns a one on that bit. If an AC or DC voltage (of sufficient magnitude, covered above) is applied it returns a zero on that bit.
