Abstract
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.
