Bus master for a bus for connection of sensors and/or ignition means

A bus master for a bus conductor for connection of at least one of impact sensors and an ignition arrangement, comprising:

• at least two bus driver arrangements, each including a respective bus driver, the at least two bus driver arrangements connectable to at least one of the impact sensors and the ignition arrangement via the bus conductor, wherein the at least two bus driver arrangements are able to receive data simultaneously with and independently of one another over the bus conductor to increase the bandwidth;
• a first multiplexer connected downstream of the at least two bus driver arrangements configured to alternate supplying data received by the at least two bus driver arrangements via the bus to a demodulator;
• and
• a processor having an upstream second multiplexer connected downstream of the at least two bus driver arrangements for alternatingly determining an instantaneous system status of the at least two bus driver arrangements as a function of quantities measured on the bus conductor.
