The present invention is related to a transmission system for sending digital data on a digital bus (1), to which are connected a number of master and slave modules. The system is characterized by the fact that a number of modules may comprise two connectors (20, 21) to said bus, and a switch (22) or switches (52, 53), allowing the interruption of said bus. This design allows an address setting procedure to take place, before starting normal operation. During this initialization, the addresses of the modules are set by consecutively closing the switches, and setting the address. Every time a switch is closed in one module, the following module can receive its address. The invention is related to several embodiments of the system allowing this procedure, and to the method of initializing such a system.
A transmission system for transmitting digital data in a time domain multiplexing mode, comprising a digital data bus, and a plurality of modules coupled to said data bus, wherein at least one of said modules of said plurality comprises two connectors, directly connected together so that data passing through said bus enters said module through one connector and leaves said module through the other connector whereby said module is able to send data to the bus and to receive data from the bus, and wherein said at least one module further comprises a first interruption device, placed in the path between said two connectors, for disconnecting the two connectors from each other so that the data transfer via said bus is interrupted.
A module coupled to a digital data bus whereon digital data is transported in a time domain multiplexing mode, said module comprising two connectors, directly connected together so that data passing through said bus enters said module through one connector and leaves said module through the other whereby said module is able to send data to the bus and to receive data from the bus, said module further comprising a first interruption device, placed in the path between said two connectors wherein the opening of said first interruption device disconnects the two connectors from each other so that the data transfer on said data bus is interrupted.
