Abstract: In a method for the serial, asynchronous and character-by-character data transmission of a data stream having multiple data words Z to Z, an additional parity data word D is generated and transmitted. The parity data word D is generated such that in a data block formed from the data words Z to Z and the additional parity word D a pre-determined parity is produced, wherein for calculating the parity different bit positions, and thus varying priorities are selected each in the data words adjacent to each other in the data stream. Further, the vertical parity is generated and transmitted for the parity data word, and for each data word Z to Z. The method substantially increases the probability that transmission errors of various origins are detected in a receiver.

Abstract: Such an electrical device (6) comprises an electrical module (8) for the purpose of communicating between the electrical module (8) and another electrical device. An identification transmitter (14) is provided which has a first position, in which the electrical module (8) is in a non-operative state, and a second position, in which the electrical module (8) is in an operative state. In addition, an identification pick-up (20) is provided which interacts with the identification transmitter (14) in the second position in order to evaluate information defined by the identification transmitter (14). The electrical device (6) makes possible, inter alia, an alternative addressing concept in which the location of a fixedly installed base (12) or the wiring to the base (12) is addressed, since the information transmitter (14) is located on the base (12).
