Abstract
The invention relates to a circuit layout for a serial transmission and reception interface, in particular for a vehicle occupant protection system, as well as a procedure for controlling the same. Existing central units, in particular vehicle occupant protection systems, featured in most cases separate serial transmission and reception interfaces for the various modules to be connected, causing costs to increase whenever an additional diagnosis module is to be connected. By means of a switchable circuit layout for the interface, this will be connected either to a communication module or to the diagnosis module. The circuit layout is particularly simple and space-saving, being set up by means of diode switches, and preferably features a potential tapping point for automatic switchover into diagnosis mode.
