An
ethernet device connector built-in module for a controllable apparatus from lighting, sound, video or
special effects engineering, for incorporating the apparatus in a chain of apparatuses serially connected by
ethernet. The construction of the built-in module allows serial control of complexly switchable apparatuses. The built-in module provides a data supply and, for example, a power supply of a chain of serially interconnected apparatuses via two external plug-in locations being interconnected via an interposed
distributor component that has an
ethernet contact interface on a PCB of the built-in module for connecting within the apparatus, the built-in module to
control electronics of the apparatus. The
distributor component is configured here to distribute a data supply
signal and optionally a power supply
signal supplied by one of the two external plug-in locations to the other one of the two external plug-in locations and the ethernet contact interface on the PCB.
