    Before You Begin The GPI-8941 cards provide an interface between openGear agents, such as DashBoard, and hardware devices that communication via the General Purpose Interface (GPI). Some devices produce outputs (GPI outputs) that are intended to either control other devices or signal their own status. When these signals are connected to inputs (GPI inputs) on the rear module, the card communicates the state of the GPIs via the openGear protocol (OGP) to DashBoard.
