Abstract (en)
The invention relates to a device and a method for monitoring the operability of a signal connection between a control unit (5) and a balise (4), wherein the signal connection is provided at least partially by at least one connecting cable (7), wherein the device (9) comprises a monitoring signal generator (10), at least one means for determining a connecting cable current (I) and at least one evaluating unit (13), wherein a monitoring signal with a monitoring frequency is injectable into the connecting cable (7), wherein the connecting cable current (I) is determinable, wherein a current portion with the monitoring frequency is determinable, wherein an incorrect operability of the signal connection is detectable if a current value of the current portion is smaller than a predetermined threshold value.
