Figure 9.2: Setting triggers using digital Input
The setting for the <Sampling interval> is needed to debounce the external push button and be
sure that only one trigger is set. The external push button can be connected to the power supply
of the car and the Digital In mentioned above.
9.2 Time stamp
The recorded messages and status messages are provided with a time stamp at the conclusion
of the reception, i.e., at the time at which a receiver could receive the message. Usually the rec-
orded messages will get a time stamp at the end of each received message. Only for the serial
interface (RS232) the time of the start of the transfer will be used.
