Abstract
A method for monitoring a serial transmission of digital data signals on two parallel data lines between mutually communicating signal processing devices in which the data signals are transmitted on the two data lines with mutually inverse signal levels. In order to ensure the operability of the input components of the signal processing devices, the signal levels of the signals which are received from the two data lines are compared individually or combined with at least one reference level limit which defines a limit of the permissible common-mode signal range for the operability of the signal processing devices.
