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.
