Abstract: This invention relates to a method of adjusting the fixture color emitted by a first and a second lighting fixture to a target color, each lighting fixture comprising at least a first and a second light source emitting light having different source colors, and said fixture color is obtained as a combination of said source colors, and said fixture color can be varied by varying the intensity of each light source; where the adjusting of said fixture color to a target color is performed by varying the intensity of said light sources based on both a first color gamut and a second color gamut respectively described by said source colors from said first lighting fixture and said second lighting fixture. The invention further relates to a light adapter and light system for adjusting the fixture color emitted by a first and a second lighting fixture to a target color and to a computer-readable medium having stored therein instructions for causing a processing unit to execute said method.

Abstract: A system that includes a network server and a number of network clients connected to the server through a daisy chained network. These network clients include a clamper circuit parallel coupled to the daisy network, with the clamper adapted to detect a signal transmitted through the daisy network and adapted to short circuit the daisy network when the signal has been detected. A detect and blocking circuit can detect a signal on the transmission line via measuring voltage or current going trough the transmission line, and as a result of a detection block or interrupt the signal. The detect and blocking circuit can be enabled and disabled by the network client controller in that a detect and blocking instance is memorized by detect and blocking circuit enabling the network client controller to acquire the detect and blocking circuit if a detect and blocking instance has occurred.
