Programming the REL-32.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).
Jumper Setup Options The common on each port may be tied to ground, 5, or 12 volts. Either side of each relay may then be tied to the common. The 8007 is shipped with all of the jumpers necessary for all possible configurations. The jumpers are parked on the B-side and are inactive until configured by the user. An example configuration is shown below: Port 4: The common is tied to ground (GND). The A-side of port-4 relay 3 (K27) is tied to the common.
