Introduction The REL-16.PCI provides 16 reed relay outputs. The outputs offer 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. The board is PCI bus specification 2.1 compliant. The REL-16.PCI is designed to be used with a variety of Operating Systems including Windows 98/NT/ME/2000/XP, Linux and DOS.

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 REL-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).

Reading the Outputs The relay ports return the ones complement of the value that is currently being used to drive the relays. When using the API the actual value is returned not the complement of the value. Writing the Outputs: The output ports are the only ports that can be written. The relays on a standard REL-16.PCI are normally open. To close a relay a one must be written to the appropriate bit.
