GPI Connection

GPI (General Purpose Interface) is a method by which electronic “pulses” from one device are used to trigger functions on another device.

This section provides instructions for connecting GPI inputs for four assignable GPI inputs. When an external device such as an automation system is connected and when remote control is enabled (using the Enable GPI triggers menu item), external pulses can control specific functions of the Lightning.

See your automation system’s manual for steps on connecting its GPI lines. The following table lists GPI input specifications.
