Abstract
A network having a series architecture and comprising an electronic master device (M) and a plurality of electronic slave devices (E.sub.1, E.sub.2, . . . ). Each electronic slave device is provided with an associated connection device (30) which enables the electronic slave device to be connected to a common communication channel (2) which interconnects the electronic slave devices and the master device. The common communication channel passes through the connection devices in order to preclude the occurrence of conflicting voltages when one of the electronic slave devices attempts to carry out a transmission to the electronic master device. For this purpose each connection device is equipped with a dedicated-line receiver and a dedicated-line transmitter in cascade, and an open-collector driver connecting the transmission part of the corresponding slave device to the input of the transmitter.
