The NMEA driver (127.127.20.X) will use the PPS signal if it is present on the DCD pin. http://doc.ntp.org/4.2.6/drivers/driver20.html provides set-up details. You don't need the PPS driver (127.127.22.X). -- Steve Kostecke <koste...@ntp.org> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
