RUT955 and EGNSS/PPS signal

Hi

I am using a RUT955 and want to sync the GPS with a lidar which takes GPRMC/GPGGA messages and the PPS (pulse per second on each full second of sattelite time/matching GPRMC message) of an EGNSS as input. I managed to get the GPRMC/GPGGA messages but cannot find anything about the PPS signal in the manual. I also cant find that signal by measuring the I/Os. can someone help?
