If the only output is a PPS than the interface to NTP is simple.  Run
the rs-232 level converted PPS into pin-1 on a serial DB9 connector,
well OK ground for PPS signal return. ( I forgot the pin number for
the ground.)  Remember that in rs232 "logic 1" is a negative voltage,
logic 0 is positive.

You will need a second reference clock to "number the seconds" but a
pool server is good enough for that
