You may want to try radioclkd2 which decodes DCF ok and uses
the SHM refclock driver. Radioclkd2 supports signals of either
polarity on DCD, CTS, DSR or RNG, also there is debug mode that
gives time between pulse edges. From pictures of connector I
can't see any connection to RxD which is used as input by
PARSE driver, nor does there appear to be a connection to DCD.
